Description

Technical Field

[0001] The present invention belongs to the technical field of water supply and drainage systems, and in particular relates to a modular combined water supply and drainage system and an installation method thereof. Background Art

[0002] In the process of construction engineering development, the research on the physical technology of construction engineering is relatively extensive and in-depth, and various technologies have made rapid progress. In recent years, various prefabricated structures have been particularly prominent. In the process of engineering construction, temporary construction engineering technology used for auxiliary construction is also developing rapidly, such as prefabricated roads, prefabricated container houses, prefabricated walls, etc. For the temporary water supply and drainage system at the construction site, China is still in the process of exploration and development. At present, there are two mainstream construction methods: one is to use a concrete cushion as the foundation, and use brickwork for maintenance on both sides or other surfaces, and then paint. This method is adopted by most construction sites, temporary office areas, and temporary living areas for employees. The characteristics of this method are that it requires more types of materials, takes a long time to construct, involves more types of construction work, is greatly affected by the weather during implementation, and has a low reuse value after use. It is easy to cause material waste and generate construction waste. When the drainage ditch surface needs to be installed with a cover plate, the process requirements for the side of the ditch are also high. In the design process of construction engineering, especially for basement structure projects, generally for the surrounding area of ​​the foundation pit retaining structure, considering the need for enclosure safety, drainage ditches are designed on the edge of the foundation pit for rainwater and foundation pit drainage needs. After the implementation of drainage ditches, water collection wells and sedimentation tanks, they cannot play a good drainage role due to various reasons. During use, they will sink, crack, collapse, and leak. In severe cases, they will cause danger to the safety of the foundation pit. In order to ensure the normal use of the drainage system, repeated maintenance is required. The second is to use corrugated pipes, PVC pipes combined with concrete and brick masonry structures, that is, corrugated pipes are used as drainage ditches, brick masonry is used as piers, water collection wells, sedimentation tanks, etc. There are two ways to bury pipes to make drainage ditches: cut and non-cut. This method has greatly improved the drainage ditch process compared to the first one, but there are also many problems. For example, if the cross-section is adopted, the ditch surface cover is not easy to set, and the drainage volume of the ditch is also limited. If the whole pipe is buried, it is difficult to remove surface water. The water collection well and sedimentation tank also have the same problems as the first method. For small construction sites and soft soil environments, it will be more difficult to construct a water supply and drainage system, and the effect after completion is not ideal. In addition, in the project, cement products are also used as water supply and drainage systems, which are expensive and difficult to install. To this end, it is necessary to develop a set of products that are easy to process in factories, easy to purchase raw materials, easy to ensure the quality of finished products, light in weight, easy to transport and install, and can form modular assembly. After installation, the appearance is good and the water supply and drainage can be guaranteed, and the product can prevent water leakage and has a low cost. After use, the product can be reused and recycled, so that the modular combination can form a temporary water supply and drainage system during the construction process. Summary of the invention

It includes the following steps:

[0040] S1. Survey and map the plane layout drawing of the water supply and drainage system at the construction site: Survey the places where water supply and drainage ditches, catch basins, and sedimentation tanks need to be set, mark the installation positions, quantities, capacities, and drainage slopes, and form drawings;

[0041] S2. Design the water supply and drainage system drawings: According to the data requirements in the surveying and mapping drawings, design the water supply and drainage drawings according to the component modules of the water supply and drainage system;

[0042] S3. According to the water supply and drainage drawings, design parameters such as the length, width, depth, wall thickness, and angle of a single-section water supply and drainage ditch module. Add corner water supply and drainage ditch modules and vehicle-crossing water supply and drainage ditch modules according to the needs of the construction site. Select the sizes of the catch basin module and the three-stage sedimentation tank module according to the drainage volume required at the construction site. It specifically includes the following parts:

[0043] 1) Select the materials for making modular products

[0044] The drainage and water supply ditch module 1, the catch basin module 3, and the three-stage sedimentation tank module 2 are made into products by plastic processing.

[0045] 2) Design the length of a single-section drainage and water supply ditch module 10

[0046] According to the operation requirements at the construction site and the loading requirements, to prevent deformation during product storage and transportation, the length of a single-section drainage and water supply ditch should not exceed 4m, as Figure 1 shown.

[0047] 3) Design the width and depth of a single-section drainage and water supply ditch module 10

[0048] The design of the width and depth of the drainage ditch is set according to the drainage volume requirements. The drainage ditch is generally long. According to the drainage slope direction, it is appropriate to set the bottom slope of the ditch to 0.5%. Generally, there is a cover plate 13 on the drainage and water supply ditch surface, as Figure 12 shown. Combining the domestic cover plate product types and models, the width of the drainage ditch at the construction site is set between 200mm and 300mm, and 250mm is the most suitable, which can be adjusted according to actual needs; the ditch depth is preferably 300mm. Due to the need of the drainage slope direction of the ditch, the ditch depth is gradually adjusted according to the slope requirements, so as to determine the dimensions of the length, width, head and tail depth of a single-section drainage and water supply ditch module.

[0049] 4) Set the wall thickness and angle of a single-section drainage and water supply ditch module 10

[0050] The thickness of the side wall and the bottom surface of the module is the same, and the value is between 1mm and 2mm; the two side walls of the module and the bottom of the ditch form an angle of 90° to 105°, as Figure 1 shown;

[0051] 5) Add rib plates to a single-section drainage and water supply ditch module 10

[0052] To prevent the lateral pressure of the soil on the side of the ditch from acting on the module, longitudinal and transverse rib plates 103 are provided on the bottom plate and the outer plates on both sides of a single-section drainage and water supply ditch module 10. The material of the rib plates 103 is the same as that of the module. The rib plate method is like the longitudinal and transverse rib plates in Figure 1 The spacing between the longitudinal and transverse ribs should not be greater than 150mm.

The connection between the head and tail ends of the modules is as Figure 2As shown, the width and depth of the female groove 102 should match the thickness and length of the male card 101. Among them, the depth of the female groove 102 and the length of the male card 101 are preferably between 5 mm and 15 mm. When connecting each section of the module, insert the male card 101 at the end of the upper section of the water supply and drainage ditch module into the female groove 102 of this section. Before inserting the male card 101, apply an appropriate amount of waterproof putty 104 into the female groove 102, such as Figure 3 As shown, it is appropriate that an appropriate amount of putty overflows after the male card 101 is inserted. Bonding and curing putty shall not be used.
