The drainage pipe is blocked, and the third floor is flooded.
There could be many reasons for the blockage of the drainage pipe and the water on the third floor could be reversed, and different solutions could be taken. ** I. Cause Analysis ** 1. ** Congestion ** - Hair, kitchen waste (rice, vegetable leaves, noodles, etc.), grease (such as lard), and other sundries may have accumulated in the pipeline, causing poor drainage and water flow to fail smoothly, resulting in water reversal on the third floor. - It could be that the pipes at the lower levels were blocked, such as the pipes below the second floor, causing the water above the third floor to be unable to drain normally and turn against the water. 2. ** In terms of installation ** - If the drainage pipes on the third floor were not installed reasonably, such as the installation position of the drainage hose being too low, it would make it easy for water to accumulate and not be discharged in time, causing water to reverse. ** 2. Solution ** 1. ** Temporary measures ** - A sealing ring could be placed at the drain outlet of the reverse water. This would fix the sewer pipe and block the gap between the hose and the sewer pipe. To a certain extent, it would reduce the reverse water situation. Even if the water flow was fast, it was not easy for the water to return from the drain. 2. ** Clear the blockage ** - ** Chemistry ** - He could use the vinegar and soda method to first drain the water in the sewer, then mix the white vinegar and soda powder, and then add hot water into the sewer to use a chemical reaction to dissolve the blockage. - The salt and soda method was also feasible. Mix 1/2 cup of salt and 1/2 cup of soda water and pour them into the sewer. This mixture would help remove the dirt on the inner wall of the pipe, expand the diameter of the pipe, and dredge the pipe. - You can also use a pipe dredge agent. According to the instructions, you usually add an appropriate amount of dredge agent and warm water (no more than 60 degrees) to make it react in the pipe and dissolve the blockage, such as hair, meat, vegetable leaves, etc. - ** Physical method ** - Using the hot water method, boiling hot water was poured into a kettle or pot, and a towel was used to block the sewer to maintain the temperature and pressure of the hot water. The flushing and softening effect of the hot water was used to dredge the pipe. - The pump method could also be tried. First, the mouth of the sewer was blocked, and fresh water was poured in. Then, the pump was continuously pumped, and through the up and down circulation, pressure was formed. The external water pressure was used to dredge the sewer, but this method was more cumbersome. - The mop method. If the blockage was urgent, the mop could be used to directly block the drain, creating pressure back and forth. Repeat 5 - 10 times to discharge the blockage. - The mineral water bottle method was to cut off the bottom of the mineral water bottle, put on gloves, and insert the mineral water bottle vertically into the sewer. Repeatedly lift and press down, and discharge the foreign matter in the sewer through the huge pressure formed in the bottle. If the toilet was blocked and the bottle was not high enough, the insulation tape could be used to stick the 502 to the disposable chopsticks and the bottle cap firmly before continuing the operation. After dredging, he had to use half a bowl of white vinegar, five pump of dishwashing liquid, and three spoonfuls of baking soda mixed with boiling water to pour it into the sewer for deep cleaning to prevent secondary blockage. 3. ** Protective measures ** - When installing the pipe, whether it was the sewer pipe of the vegetable basin or the pipe under the bathroom cabinet, it must be higher than the ground. At the same time, the water hose should be plugged in to help prevent water from flowing back. Read more exciting novels for free
The floor drain pipe is blocked and water is flowing out
If the floor drain pipe is blocked and the water is reversed, the following treatment methods can be taken: 1. ** Draining and dredging method **: First, flush the floor drain continuously, then choose the U-shaped iron wire to extend into the floor drain and rotate it continuously to rotate the blocked foreign matter down. Finally, flush it away with clean water. 2. ** Air pumping method **: Prepare a pump, put the rubber tube of the pump into the drain pipe of the floor drain, seal the surroundings of the floor drain, and then put enough water into it. Use this space to pump air into the floor drain to quickly clear the drain. 3. ** Vinegar and baking soda method **: First pour baking soda into a bowl, then add vinegar and a small amount of water. After mixing it, he poured it into the drain. After a while, the drain would clear itself. 4. Soda plus vinegar dredging method: pour half a cup of cooked soda into the blocked floor drain, then pour half a cup of vinegar. The soda and vinegar will react to remove the grease adhered to the pipe, thus clearing the pipe. 5. [Alkaline dredging method: Throw the kerosene into the sewer pipe and pour some hot water into the pipe. When the kerosene meets the hot water, it will undergo a chemical change, causing the temperature in the pipe to rise rapidly. The grease in the pipe will melt and be discharged with the water.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Spiral drainage pipe
Spiral drainage pipe was a kind of pipe used in building drainage system, which had some characteristics and advantages. Spiral drainage pipe has the following characteristics: 1. Reduce noise: The design of the spiral drainage pipe can effectively reduce the noise pollution caused by drainage. The measured results showed that compared with the traditional cast iron drainage pipe, the noise of the spiral drainage pipe was about 2 to 4 decibels lower, and it had a silencing effect. 2. To prevent the damage of the floor drain seal: The spiral structure inside the spiral drainage pipe can reduce the pressure fluctuation in the pipe, avoid the damage of the water seal caused by the negative pressure of the upper user and the positive pressure of the bottom user, and improve the stability of the drainage system. 3. Increase drainage efficiency: The internal spiral structure of the spiral drainage pipe increases the friction resistance of the water flow, preventing the water flow from blocking the pipe due to inertia, improving drainage efficiency and reducing the occurrence of blockage accidents. 4. [Double silencing effect: Hollow wall spiral drainage pipe is a special structure of spiral drainage pipe. It has a double-layer structure and honeycomb-shaped holes, which can further isolate noise and have a better silencing effect.] In general, the spiral drainage pipe had the advantages of reducing noise, preventing the damage of the floor drain seal, and improving drainage efficiency. They are commonly used in the drainage system of buildings, especially for the drainage of single standpipes in high-rise buildings.
Open ditch drainage and underground pipe drainage
Open ditch drainage and underground pipe drainage were two common methods of farmland drainage. Open ditch drainage was a method of digging drainage ditches to form a drainage ditch network. Water would flow from the field ditch network into the water transmission ditch network and finally into the drainage area (river, lake, sea). Underground drainage was a method of burying pipes underground to drain water by removing excess water from the farmland soil and lowering the water level. The underground pipe drainage could be used to filter and seep water by using sand and stone bedding, laying thick plastic pipes and crushed sand. Open ditch drainage was suitable for soil layers with better geological conditions, while underground pipe drainage could effectively control the underground water level, save land, and have a better drainage effect.
The horizontal drainage pipe is connected with the horizontal pipe
The horizontal drainage pipes shall be connected with the horizontal drainage pipes by oblique three-way, oblique four-way or three-way and four-way along the water. To be specific, the connection between the horizontal sewage pipes should not be made with a straight three-way or a straight four-way, but with an inclined three-way or an inclined four-way or a straight three-way or a straight four-way. These connections could ensure the normal operation and drainage effect of the drainage pipeline.
Horizontal branch pipe and horizontal main pipe of drainage
Horizontal branch pipes and horizontal main pipes were two types of pipes in the drainage system of buildings. The horizontal branch pipe was a horizontal pipe section connecting the sewage collection device drain pipe and the vertical drainage pipe, and was used to send sewage from the sewage collection devices to the vertical drainage pipe. The horizontal branch pipe should have a certain slope to facilitate smooth drainage. The horizontal main pipe was a pipe section that connected several drainage vertical pipes to the discharge pipe, mainly to receive the drainage of the horizontal branch pipe. The connection point of the horizontal branch pipe and the horizontal main pipe has a certain distance from the bottom of the vertical drainage pipe to ensure the normal operation of the drainage system. The specific connection requirements could refer to the relevant specifications and design standards.
The difference between upvee spiral pipe and drainage pipe
The difference between the UpPVP spiral pipe and the drainage pipe was that the UpPVP spiral pipe was a special type of drainage pipe with a noise reduction function. The inner wall was smooth, and the noise during drainage was low. The drainage pipe was an ordinary pipe with no noise reduction function. Therefore, the upvee spiral pipe could reduce noise during the drainage process, but the drainage pipe did not have this function.
The drainage horizontal branch pipe is connected with the vertical pipe.
When the horizontal drainage branch pipe is connected to the vertical pipe, different connection methods can be used. According to the Design Standard for Building Water and Waste Water, when the sanitary ware drainage pipe is vertically connected to the horizontal drainage pipe, a 90° inclined tee should be used. When the horizontal branch pipe is connected with the vertical pipe, it can adopt a three-way or four-way downstream pipe and a 45° inclined three-way or 45° inclined four-way pipe. In a special single-standpipe system, the horizontal branch pipe and the standpipe can be connected by special accessories. In addition, according to some provisions of the Building Water and Waste Design Code, when the drainage stand pipe is only equipped with a top vent pipe, the vertical distance between the lowest drainage horizontal branch pipe and the stand pipe bottom shall not be less than the specified distance. According to the Connection Design and Material Selection of Building Drainpipe Branch and Horizontal Main, when the drainage branch pipe on the upper layer of the horizontal main drainage pipe is connected to the horizontal main drainage pipe, it is recommended to use a 45° inclined tee to connect it from the top of the horizontal main drainage pipe. To sum up, when the horizontal drainage branch pipe is connected to the vertical pipe, different connection methods such as 90° inclined three-way, downstream three-way or downstream four-way, 45° inclined three-way or 45° inclined four-way can be used.
same floor drainage
Same-floor drainage was a drainage method for sanitary appliances. Its characteristic was that the drainage pipe did not need to pass through the floor, but was laid in the same floor and connected to the drainage standpipe. There were two main forms of same-floor drainage: wall-row zero-drop same-floor drainage and slightly-drop same-floor drainage. The wall row zero-drop drainage on the same floor meant that the drainage pipe went along the wall and did not occupy the vertical floor height. The bathroom could maintain the same floor height as other rooms, and the design freedom was higher, and it was beautiful and practical. The same floor drainage with micro-descending plates was a common form in China. It required the installation of dry area floor drain, which could almost achieve zero floor height difference without occupying vertical floor height. The difference between the same floor drainage and the different floor drainage was the layout of the bathroom appliances, the aesthetics of the house, and the drainage noise. The advantages of same-floor drainage were high degree of freedom in layout, beautiful houses, and low drainage noise, but there were also shortcomings such as high construction cost and difficult maintenance. In general, same-floor drainage was a healthier, more convenient, and more beautiful drainage method.
The second floor was flooded.
The main reasons for the second floor's overflow were as follows: 1. ** Design and construction of the pipeline ** - The pipe diameter is too thin, there is a problem with the vent pipe, the buried pipeline is damaged, there are obstacles in the pipe, the bottom horizontal pipe is too long, the bend angle is too sharp, the slope is not enough, or even the slope is reversed, the distance between the lowest horizontal branch pipe and the bottom of the vertical pipe or the bottom horizontal pipe is not up to the standard, and the elbow radius is too small when the vertical pipe turns horizontally (the standard is two 45-degree elbows or four times the diameter of the large elbow or variable diameter elbow), etc., will lead to insufficient drainage capacity. Even if the design and construction of the pipeline reached the standard, there was still a small probability of water reversal. However, some of the second-floor pipes were completely in line with the specifications. The distance between the horizontal pipe and the sewage well was short, and the flushing ability was sufficient. The risk of water reversal was very small. - The drainage overflow function of the three-way pipe connected to the bottom of the sewage pipe and the ventilation pipe was relatively strong, which could prevent water from flowing back to a certain extent. 2. ** Construction waste blockage ** - During the construction and renovation stage, some workers had bad habits. They poured cement, glue, and other construction waste into the sewer, which could easily block the pipeline and cause water to flow back. Or they would stick to the inner wall of the pipeline and make the actual diameter smaller, resulting in a decrease in sewage discharge capacity and a hidden danger of water return. However, the normal pipeline flushing ability was strong, and some of the construction debris might be washed away. Such problems rarely occurred in the hardcover room. 3. ** Inappropriate or careless use by the residents upstairs and maintenance issues ** - Upstairs residents would drop large sundries such as sanitary napkins, plastic, towels, hair, bottles, etc. into the sewer through the toilet bowl, which would cause blockage. In places where toilets were commonly used, due to the small internal diameter of the toilet, large sundries were easy to get stuck in the toilet, so the blockage of the toilet after the renovation period was relatively rare. - The whole bucket of water upstairs was poured into the toilet, and the water flow in the vertical pipe was too large or there was a strong pressure, causing the reverse flow and bubbling. When the food residue in the vegetable washing basin was poured into the kitchen pipe, the oil stain was easy to condense and solidify to form a stain or blockage. If the property was negligent or incomplete, it was easy to cause the reverse flow. There were the following solutions to the problem of water overflow on the second floor: 1. ** Rectification, maintenance, and dredging of pipes ** - For new houses and houses under the guarantee period, they would first find the developer or property management to be responsible for them. If it was a problem with the design and construction of the pipeline, it had to be repaired or rebuilt. At least, it had to meet the specifications of the Jianshui Standard and pass the ball test. During the renovation, the developer may be required to substantially increase the slope of the horizontal pipe. If there is a sealing ring or accumulation protruding from the inner wall of the pipe at the pipe joint, it will affect the passage of sewage and dirt, especially if the horizontal pipe has been blocked. It is necessary to remove the bulge at the joint and greatly increase the slope. When the bottom horizontal pipe is a cast iron pipe, it can be disassembled and cleaned before being installed again. The property can use the vehicle high-pressure water flushing dredge machine (strong dredging ability and does not damage the pipeline) and other equipment to dredge. For the pipeline that is easy to reverse, the inspection and dredging should be strengthened. - In the event of a water spill, the property owner must immediately rush to the building and inform the upstairs to suspend water use or close the unit water supply valve to stop the water spill, dredge the pipeline and clean up the hygiene. If the property owner suffers losses due to the property, the property owner shall compensate according to law. 2. ** Regarding preventive and other measures ** - The addition of a check valve during renovation could prevent the kitchen pipeline and the drainage pipeline of the bathroom from being filled with sewage. - The second floor had an independent diving system, which could solve the problem of water returning once and for all. - A water alarm was installed to send out a remote alarm when water returned to the ground to avoid greater losses. - It can be installed with a pipe sealing plug, and its multi-layer silica gel sealing ring can seal the sewer pipe. The gravity check valve at the bottom can only be opened when draining water, and it is usually closed. It can effectively prevent insects, odor, and overflow. It is suitable for washing machines, washbasins, sink pipes, and other sewer pipes. At the same time, all owners and tenants should be reminded to use the drainage pipe in a civilized manner. The property management can post a notice board in a prominent position, or remind the residents to use the pipe reasonably according to the law through mass text messages and owner groups. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What's a horizontal drainage pipe?
The horizontal main drainage pipe was a horizontal pipe section connecting the drainage pipe of the sewage collection device and the vertical drainage pipe. It could send the sewage flowing out of the sewage collection device to the vertical drainage pipe. It should have a certain slope, and the end connected to the drainage stand pipe should be lower to facilitate drainage.
