The top of the sump 116 is connected to the bottom of the sump 111. The pump 131 is arranged in the sump 116. By arranging the pump 131 and the drain pipe 132, the water in the sump 111 can be quickly discharged. The other end of the drain pipe 132 in this embodiment is used to connect to the municipal drainage system. By setting up the sump 116, the water collected in the sump 111 can be fully discharged. The connection between the sump 116 and the bottom of the sump 111 can ensure that the accumulated water in the entire basement can be fully collected and discharged, which can prevent the water flow from being retained and diffused in the basement, and effectively reduce the area and depth of the accumulated water in the basement.

The steel mesh 121 is arranged in the concrete layer 12, and is laid on the hydrophobic layer 14, and is tied to the base layer 11 by a second bolt, which strengthens the tensile strength and bearing capacity of the concrete layer 12, and improves the strength and stability of the overall structure of the basement. And the steel mesh 121 in the concrete layer 12 can effectively control the crack expansion of the concrete, enhance the shear resistance and impact resistance of the concrete, which helps to improve the durability of the concrete layer 12 and extend the service life of the basement. In addition, the steel mesh 121 is tied to the base layer 11 by a second bolt, firmly connecting the hydrophobic layer 14 and the base layer 11, and preventing the hydrophobic layer 14 from loosening or displacement during use.

Filling the elastic glue 114 in the slit 113 can increase the durability of the concrete structure. The elastic glue 114 has certain flexibility and elasticity, and can absorb and disperse the movement and vibration of the structure, reducing the stress concentration of the structure. At the same time, the elastic glue 114 can also prevent moisture, dust and other debris from entering the slit 113, protecting the concrete structure from corrosion and damage.

[0062] The working principle of this utility model:

[0063] 1. Cleaning up the base 11

[0064] Clean the floor with clean water and absorb all the excess water before pouring concrete, which is beneficial to improving the bonding strength between the base layer 11 and the hydrophobic layer 14. During the concrete construction, ensure that there is no excess water on the surface to ensure the cleanliness of the floor.

[0065] 2. Laying of hydrophobic layer 14

[0067] Before laying the first drain board 141, a vertical line must be drawn on the wall. Then, using the dividing ink line, the laying order is from top to bottom, starting from the corner. When laying, it is necessary to ensure that the top drain board 141 is flattened first, and then pushed down, and the drain board 141 is fixed with the first bolt after it is close to the base layer 11; then, the adjacent drain boards 141 are laid in the vertical direction; the overlapping drain boards 141 at the horizontal and vertical corners of the basement must be fixed with 2-3 bolts; the interfaces of the overlapping drain boards 141 are sealed with asphalt oil.

[0068] The support platform 1412 between adjacent drain plates 141 is engaged with the filling groove to increase the connection stability between the drain plates 141 .

[0069] 3. Isolation seam

[0070] 10mm pre-plasticized panels are provided along the wall 15, the column 16 and the edge of the equipment foundation to prevent the concrete from cracking at the connection with the newly poured concrete.

[0071] 4. Steel mesh 121 binding

[0072] The steel mesh 121 is laid on the hydrophobic layer 14, and the steel mesh 121 is tied to the base layer 11 by a second bolt, and the second bolt penetrates the hydrophobic layer 14. The concrete reinforcement C8@150 is arranged in a single layer and in two directions, that is, 8mm diameter steel bars are arranged in a tic-tac-toe pattern with a spacing of 150mm throughout the entire plate.

[0073] In addition, in this embodiment, the connection between the second bolt and the hydrophobic layer is also sealed by asphalt oil.

[0074] 5. Concrete pouring and leveling

[0075] 6. Cutting 113 and maintenance

[0076] Induce concrete to form regular shrinkage sawing cracks in specified areas, eliminate irregular shrinkage cracks, and improve the overall regularity and aesthetics of the concrete floor.

[0077] (1) Cutting depth: Determined by the floor thickness. Generally, the cutting depth should not be less than 1 / 3 of the concrete thickness. Cutting width: 4-5mm.

[0078] (2) Cut along the column axis at intervals of 3 to 6 meters according to the spacing required by the construction deepening drawing. The middle column 16 can be cut using a diamond-shaped cut 113, which can release the shallow internal stress in the leveling layer concrete at the corners of the column.

[0079] (3) Use a water suction machine to clean and remove the mud produced by cutting while cutting.

[0080] (4) The cut seams are filled with elastic glue 114. The elastic glue 114 in this embodiment is an elastic isolation glue.

[0081] After the construction of the drainage structure is completed and maintained, it can be put into use. In addition, a protective net 117 can be set above the sump 111 in this embodiment to protect the entrance of the sump 111 and improve the safety of the structure.

[0082] This completes the working process of the basement drainage structure of the preferred embodiment.

[0083] Water penetrates the base layer 11 and enters the bottom side of the drainage board body 1411 through the base layer 11. Since the support of the support platform 1412 provides sufficient flow space for water, the water flows to the outer periphery of the support platform 1412 and is directed to the water collection tank 116, which greatly reduces the phenomenon of moisture in the basement caused by water penetration. In addition, the drainage board construction in this embodiment replaces the traditional pebble hydrophobic layer, which has the advantages of saving construction time, labor and energy, reducing costs and reducing the load of the building.

[0084] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
