Sand and stone inverted filter well construction method detailed drawing
First of all, they used soil bags to build a well around the water hole to ensure that the bottom of the well was in close contact with the ground. Then, according to the requirements of the three-layer inverted filter, the materials were laid in layers in the well, the order was fine at the bottom and coarse at the top, that is, first, the coarse sand was laid, then the stone chips were laid, and finally the gravel was laid, and the top layer was pressed with stone blocks or soil bags. The height of the well should be based on the principle of preventing sand and mud from being carried in the process of water gushing. Generally, it should not exceed 1500mm to avoid new piping danger areas near the well. When filling the well, the sundries in the well must be cleaned up first. Woven bags or sacks can also be used to fill the well with soil and sand. If the piping outlet is not large and the water gushing is small, the inverted filter material shall be laid one by one from the fine inverted filter material to the coarse inverted filter material. The fine inverted filter material shall be filled first, then the transition inverted filter material shall be filled, and finally the coarse inverted filter material shall be filled. The thickness of each layer of inverted filter material shall be 200 - 300mm. The particle composition of the inverted filter material shall be selected and prepared in advance according to the particle grading of the protected soil. If the diameter and water flow of the piping outlet have a large change, it is possible to pile up stones or gravel with larger grain sizes to reduce the water potential.

Construction Method of Taiping Courtyard
The construction method of Taiping Courtyard included two aspects: site selection and construction. First of all, the location of Taiping Courtyard was very particular. It was built on a small island in Liujing River, and the surrounding banks were relatively low, making the courtyard surrounded by water on three sides, which had a very good defensive effect. There was only a small path to the entrance, and other places could only be entered by water or from the sky. It was almost easy to defend and difficult to attack. In addition, there were high walls around the courtyard, which had the ability to resist heavy sniper rifles. Secondly, the architectural style of Taiping Courtyard was very unique, as it blended in with the terrain, direction, and surrounding environment. The wall was sturdy and cleverly designed, blocking the prying eyes of the outside world. In addition, there were some mechanisms and secrets inside the courtyard. The specific details needed to be further watched by watching the " Joy of Life " TV series or reading the original work to understand.

The structure of the moving sand dune was map A. According to the description in document 2, crescent-shaped dunes were shaped like a crescent moon, with gentle windward slopes and steep leeward slopes. And document 3 also mentioned that the moving sand dune was a single-layer curved structure. Therefore, it could be confirmed that Diagram A was the structural diagram of a moving sand dune.
Can the sand at the construction site grow flowers?
He could plant flowers. The sand on the construction site could be used to grow flowers, but there were some things to pay attention to when using it. Sand itself had no nutrients, so it could not be used alone. It needed to be mixed with garden soil, peaty soil, and rotten leaf soil to ensure the breathability of the soil and the nutrition of the plants. It was best to disinfect the sand before using it to ensure the cleanliness of the sand. If the sand contained lime, it was not suitable for growing flowers. Using an appropriate amount of sand could improve the soil's breathability, which was helpful for plant growth. However, using too much sand would lead to insufficient fertility in the soil. Therefore, when planting flowers, it was best to mix sand with other soil to achieve the best planting effect.
How to create a construction cartoon drawing?

The Method of Preparing the Construction Project's Bids
The preparation method of the construction project bidding documents is as follows: 1. ** Information capture and document purchase **: Once the bidder tracks the project, it is necessary to capture relevant information and purchase the bidding documents when the information is confirmed. 2. ** Interpretation of the bidding documents **: After purchasing the bidding documents, read and understand their contents carefully to find out the requirements and intentions of the bidder. Focus on the bidding instructions, special terms, design drawings, project scope, bill of quantities, etc., especially to clarify whether there are any special requirements. 3. ** In-depth analysis of the bidding documents in combination with the site conditions **: further analysis in combination with the site survey and the results of the bid preparation meeting. If it involves the bill of quantities, it must be checked carefully. If there is any major discrepancy in the bill of quantities, especially missing items, it can be checked by the bidder and asked for written confirmation. This work is especially important for a fixed price contract. 4. ** Prepare the construction plan or construction organization design **: Prepare it based on the design drawings, technical specifications, the amount of work after review, the date of commencement and completion required by the bidding documents, and the survey results of market materials, mechanical equipment, and labor prices. The contents included construction procedures, plans, construction methods, construction progress plans, construction machinery, materials, equipment selection, temporary production and living facilities arrangements, labor plans, construction site layout and space layout, etc. They had to reduce costs and increase profits as much as possible under the premise of ensuring the construction period and project quality. 5. ** Project valuation, profit policy and offer **: According to the price structure of the project, the reasonable valuation of the project, determine the feasible profit policy, correctly calculate and determine the bidding price, and the price must not be lower than the cost. 6. ** Form and prepare the bidding documents **: The bidding documents shall be prepared in full accordance with the requirements of the bidding documents and respond to their substantial requirements and conditions. No additional conditions shall be attached. Generally, it should include the tender, the annex of the tender, the tender guarantee, the qualification certificate of the legal representative, the power of attorney, the list of quantities and the price list, the construction planning or construction organization design, the construction organization table, the candidates and resumes of the main project management personnel, the situation of the project to be subcontracted and the sub-contractor (if any), and other necessary attachments and information. 7. ** Submit bidding documents **: Send the sealed bidding documents to the bidding location before the deadline required by the bidding documents. After the submission and before the deadline for bidding, the bid documents can be supplemented, modified or withdrawn, but they must be prepared, sealed and marked according to the regulations, and notified in writing to the tenderers. The supplemented and modified contents are part of the bid documents. In addition, the correct quota should be used in the preparation of the project budget price.(If the Owner does not specify, the latest national quota of the same industry will be used). Considering the price fluctuation during the construction period, the list of quantities given by the Owner shall prevail.(Without written approval, it is not allowed to adjust the obviously wrong quantities). The cost of other projects shall be listed according to the requirements and reviewed by others after the preparation is completed. At the same time, the project budget and the construction organization design shall be unified. The construction plan will affect the budget price and the success or failure of the bidding. According to the site inspection, several sets of plans shall be determined to calculate and compare to determine a reasonable and economical plan. It is best to arrange the construction period 10 days ahead of the time specified by the Owner. If it is not a secret bid, you can consider matching it with BIM renderings. Pay attention to the layout and do not mess up the template. To improve the targeting and landing of the tender, it should be customized around the project.

The most detailed method of choosing the day
The method of choosing the day of the star, the full name of which was the method of choosing the day of the star of the seven policies and four arcs, originated from Yang Yunsong, the national teacher of the Tang Dynasty. Its core idea was to calculate the positions and movement patterns of the sun, moon, and stars (the seven policies of the sun, moon, metal, water, wood, fire, and earth), and choose favorable space-time points to carry out various activities in order to achieve the goal of seeking good fortune and avoiding evil and changing fate. However, the detailed calculation method was very complicated and difficult. In the feudal dynasty, the method of choosing the date of the star was only used in the palace, and it was not easy for the people to know. For example, in the early years of the Ming Dynasty, the decree of "those who study the calendar will be sent to Xu, and those who make the calendar will be executed" was issued, strictly prohibiting the common people from learning. In the Guangxu period of the Qing Dynasty,"The Origin of the Imperial Astronomical Phenomenon", 1 - 4 was the practice of the Imperial Astronomical Supervisor, but the content was difficult, and even a well-learned person could not get started. Although there was a folk book called Tian Bu Zhen Yuan, which involved calculating the positions of the stars in the sky and the planets, it was necessary to check the ephemeris of the position of the planets and the log table. At that time, China did not have the concept of spherical astronomy, which also led to people who wanted to learn to have no way to learn. Although there were inheritances in the folk school, most of them did not understand the true principles. They only knew the calculation steps and made many mistakes. In general, the theoretical basis of the Heavenly Star Method was a combination of ancient astronomy and the Book of Changes. It required a deep knowledge of astronomy and the Book of Changes. It also required observing the astronomical phenomena and analyzing the laws of the stars to calculate good or bad luck and the trend of fate. However, the specific and detailed operation method was difficult to explain in a simple way. The novel,"The Story of the Shepherd God", is equally exciting. Everyone is welcome to click and read it!
A detailed description of the teaching reflection method
The teaching reflection method mainly includes the following aspects: 1. [Why do you think? The law of settling down?] It was necessary to clarify that the purpose of teaching reflection was to settle down the law of education. From the preparation of the lesson to the analysis after class, he thought about what he thought was the bright spot or the bad spot. When the teaching result was consistent with the presupposition, the positive analysis was carried out. Otherwise, the negative analysis was carried out. 2. [What to think about? Give up the surface and take the point.] Writing teaching reflection should focus on one point to settle the law, not to pursue comprehensiveness. To be specific, they could use the method of blooming in the center, merging similar species, or grasping the main and leaving the secondary. 3. [Where to Think-A detailed analysis]: Reflection based on teaching notes. First, present the situation related to the reflection points in the classroom, let the facts speak; second, analyze the teaching records in detail, verify their own feelings layer by layer; finally, sum up the simple teaching rules. 4. ** How to Think-Layer Breakthrough **: First, divide the teaching summary into several levels around the main theme. Then, analyze each level in detail, including the students 'learning, the teacher's teaching, the classroom situation, the teacher-student interaction, and so on. Finally, look at the main theme again, connect the analysis of each level, and choose the content reasonably to achieve clear levels and detailed content. 5. ** In terms of frequency **: It is more appropriate to use the method of "thinking in every class and learning once a week". In other words, he could simply record the reflection content for each lesson and carefully write one piece a week. This would ensure the quality of teaching reflection. At the same time, the method of supervising once a week could be implemented to cultivate the habit of teachers writing teaching reflections. According to the law of habit formation, most teachers could form the habit of writing once a week after one semester, and they could get used to this writing frequency after three semesters. 6. ** In terms of interaction and comments **, they should prioritize " ingenuity ", seamlessly connect with each other's hearts, timely confirm the advantages of reflection, tactfully point out existing problems, and give suggestions. There were five principles for " ingenuity " in focusing, namely, pointing out the direction, timely feedback, equal expectations, appreciation and nitpicking, and asking for details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
