The anti-seepage component 41 is arranged on the sump base 2 to improve the anti-seepage and anti-cracking effects of the sump base 2 and to form a stable frame structure inside the sump base 2. The drainage component 42 is arranged on the sump base 2 to discharge the water flow inside the sump base 2 and reduce the urban drainage pressure.

The anti-seepage layer 413 is fixed to the inner bottom wall of the sump base 2. The anti-seepage layer 413 can prevent the water stored in the sump from seeping into the ground. Due to the vibration of the surface and the ground, the inner side of the sump base 2 and the anti-seepage layer 413 are easily cracked, resulting in The stored water flows into the ground, the first support plate 411 is fixed to the upper surface of the impermeable layer 413, and a plurality of first support steel bars 412 are evenly fixed to the upper surface of the first support plate 411. The first support plate 411 supports the interior of the sump base 2 to improve the water storage performance of the sump base 2. The second support plate 414 is fixed to the left side of the groove 43, and a plurality of second support steel bars 415 are equidistantly fixed to the side of the second support plate 414 away from the groove 43. The third support plate 416 is fixed to the right side of the groove 43, and a plurality of third support steel bars 417 are equidistantly fixed to the The third support plate 416 is away from the side of the groove 43, the fourth support plate 418 is fixed to the lower surface of the groove 43, and multiple fourth support steel bars 419 are evenly fixed to the lower surface of the fourth support plate 418. The second support plate 414, the third support plate 416, and the fourth support plate 418 can support the top of the sump base 2, thereby preventing the sump base 2 from collapsing. The second support steel bar 415 is laid on the second support plate 414, the third support steel bar 417 is laid on the third support plate 416, and the fourth support steel bar 419 is laid on the fourth support plate 4 18, a stable frame structure is formed inside the sump base 2.

The drainage component 42 includes a drainage pipe 421. An installation hole 422 is provided on the inner bottom wall of the sump base 2. The drainage pipe 421 is fixed to the inner side of the installation hole 422. When the water level inside the sump base 2 reaches a certain height, the water level will reach the height of the drainage pipe 421. The drainage pipe 421 can discharge excess water from the sump base 2 to reduce the drainage pressure in the city.

[0030] It should be noted that a groove 43 is provided on the upper surface of the finished ground 1 of the building, and a plurality of water holes 44 are provided on the inner bottom wall of the groove 43 and are evenly distributed on the inner bottom wall of the groove 43. The water holes 44 and the fourth support plate 418 are staggered, and external precipitation flows into the groove 43, and the water flows through the water holes 44 into the sump base 2 for storage, thereby reducing the external water flow pressure and avoiding flooding.

[0031] The working principle of the above embodiment is:

[0032] (1) The main function of the sump base 2 is to guide rainwater or surface water from the surrounding area into the pit through a surface drainage system or other means. This helps to slow down the speed of rainwater runoff, prevent floods, and provide water sources when needed. After the internal space of the sump base 2 is dug, a ground beam 3 is installed inside. Through the cooperation of the ground beam 3, the internal space of the sump base 2 can be supported, thereby improving the stability of the interior of the sump base 2 and avoiding excessive pressure above the ground 1 after the building is completed, which causes the interior of the sump base 2 to collapse and affect the water collection effect inside the sump base 2. After the construction of the sump base 2 is completed, a first support plate 411 is installed on the inner wall of the sump base 2. The first support plate 411 supports the interior of the sump base 2 and improves the water storage performance of the sump base 2. The sump base 2 is usually designed to be able to store a certain amount of water. This water can be used during droughts or other times when water is needed, thereby helping to solve the problem of water resource management. The impermeable layer 413 can prevent the water stored in the sump base 2 from seeping into the ground, preventing the water stored in the sump base 2 from flowing into the ground.

[0033] (2) External precipitation flows into the groove 43, and the water flows into the sump base 2 through the water holes 44 and is stored, thereby reducing the external water flow pressure and avoiding flooding. Due to the vibration of the surface and underground, the inner side of the sump base 2 and the anti-seepage layer 413 are easily cracked, causing the stored water to seep into the underground. Therefore, installing the first support steel bar 412 on the first support plate 411 can improve the stability and protection of the first support plate 411. The second support plate 414, the third support plate 416, and the fourth support plate 418 can support the top of the sump base 2, thereby avoiding the sump base The sump base 2 collapses, the second supporting steel bars 415 are laid on the second supporting plate 414, the third supporting steel bars 417 are laid on the third supporting plate 416, and the fourth supporting steel bars 419 are laid on the fourth supporting plate 418, so that a stable frame structure is formed inside the sump base 2. When subjected to vibration, the sump base 2 is not prone to cracking and water seepage, thereby improving the anti-seepage and anti-cracking effects of the sump base 2. When the water level inside the sump base 2 reaches a certain height, the water level will reach the height of the drain pipe 421, and the drain pipe 421 can discharge excess water inside the sump, thereby reducing the drainage pressure in the city.
