AI Technical Summary
In existing technologies, basement concrete walls still suffer from water leakage under low water pressure conditions, especially after prolonged contact and immersion, water can still seep into the basement.
The system employs a combination structure consisting of a seepage tank, a lower waterproof pad, a top permeable filter cloth, an upper waterproof pad, and internal supporting gravel to form a seepage channel away from the concrete wall. Through the cooperation of a pumping channel and a bottom-opening cleaning pipe, the system achieves the external discharge of water and the flushing of the internal supporting gravel.
This effectively prevents water from coming into contact with the basement concrete walls, preventing leakage and ensuring that water is discharged through the leakage channels. It also prevents the internal support gravel from being blocked by mud and sand, thus improving the anti-leakage effect.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of basement anti-seepage technology, specifically relating to a treatment device for anti-seepage during basement concrete construction. Background Technology
[0002] The concrete walls on the outside of the basement are in direct contact with the external soil. Due to the small pores inside the concrete, when water seeps into the external soil, some water will seep through the concrete into the basement under the influence of external water pressure and the pore characteristics of the concrete itself. Currently, drainage pipes are installed at the bottom of the concrete walls to reduce the water pressure outside the concrete walls and prevent leakage. However, in actual use, when water seeps into the soil, the basement walls are always in contact with the water in the soil. After prolonged contact and soaking, the basement concrete walls will still be saturated under low water pressure, and water will still seep into the basement. Utility Model Content

[0017] Please see Figures 1-3 The present invention provides the following technical solution: a treatment device for preventing seepage in basement concrete construction, comprising a seepage pool 1, a lower waterproof pad 2 laid on top of the seepage pool 1, a top permeable filter cloth 21 fixedly connected to the inner wall of the lower waterproof pad 2, an upper waterproof pad 22 provided on one side of the lower waterproof pad 2 and the top permeable filter cloth 21, the seepage pool 1, the lower waterproof pad 2, the top permeable filter cloth 21 and the upper waterproof pad 22 being filled with inner supporting gravel 3, a pumping channel 4 fixedly connected to one side of the seepage pool 1, a bottom-opening cleaning pipe 5 filled in the inner supporting gravel 3 located above, and a water injection pipe 51 fixedly connected to the top of the bottom-opening cleaning pipe 5.
[0018] In this implementation plan: During construction, a trench is excavated at the construction location of the basement concrete wall. The seepage pool 1 is installed in the trench. Then, a lower waterproofing pad 2 is laid on the inclined inner wall of the foundation pit, with one end of the lower waterproofing pad 2 extending into the interior of the seepage pool 1. Next, a top permeable filter cloth 21 is fixedly connected to the inner wall of the lower waterproofing pad 2, and the top permeable filter cloth 21 is bent away from the basement concrete wall. Finally, some of the internal supporting gravel 3 is laid inside the seepage pool 1 and on top of the lower waterproofing pad 2. Then, the upper waterproof mat 22 is laid on top of the inner supporting gravel 3, and the bottom permeable filter cloth 23 is laid on top of the seepage pool 1. Next, soil is filled into the foundation pit inside the upper waterproof mat 22. Then, the top of the upper waterproof mat 22 is laid on top of the soil, and the remaining inner supporting gravel 3 is laid on top of the upper waterproof mat 22. The bottom-opening cleaning pipe 5 is buried in the inner supporting gravel 3. Then, the top permeable filter cloth 21 is covered on top of the inner supporting gravel 3, and the water injection pipe 51 extends upward through the top permeable filter cloth 21. Subsequently, earth was laid on top of the permeable filter cloth 21 to fill and level the foundation pit. After construction, the lower waterproof pad 2, the top permeable filter cloth 21, the upper waterproof pad 22, and the inner supporting gravel 3 together form a water seepage channel away from the basement concrete wall. Water seeps down through the top permeable filter cloth 21 into the inner supporting gravel 3, and is guided downward by the lower waterproof pad 2 and the upper waterproof pad 22. During the seepage process, it will not come into contact with the basement concrete wall. After the water enters the seepage pool 1, it is pumped out. Water is pumped out through channel 4 to effectively prevent water seepage into the concrete walls of the basement. When it is necessary to flush the internal supporting gravel 3, water is injected into the bottom opening cleaning pipe 5 through the water injection pipe 51. The clean water enters the internal supporting gravel 3 through the hole at the bottom of the bottom opening cleaning pipe 5, flushing the mud and sand into the seepage pool 1 and then discharged through the pumping channel 4. The water inlet speed is controlled during flushing. The water pump 41 can be used in conjunction with an external water level sensor and control system to automatically pump water by detecting the water level in the pumping channel 4.
[0019] Both the top permeable filter cloth 21 and the upper water-proof pad 22 are distributed in a "V" shape; the "V" shape distribution can divert excess water to a position away from the concrete wall.
[0020] A bottom permeable filter cloth 23 is fixedly connected to one side of the upper water-proof pad 22. The bottom permeable filter cloth 23 is laid above the seepage pool 1. By setting the bottom permeable filter cloth 23, a large amount of mud and sand can be prevented from entering the seepage pool 1, and the seepage effect can be maintained.
[0021] The bottom of the upper waterproof pad 22 is fixedly connected to a positioning rod 24; by setting the positioning rod 24, the upper waterproof pad 22 can be positioned to prevent the upper waterproof pad 22 from moving away from the concrete wall.
[0022] A water pump 41 is installed at the top of the water pumping channel 4, and an underground protective pool 42 is installed on the outside of the water pump 41. By setting up the water pump 41, it can cooperate with the water pumping channel 4 to pump water from the seepage pool 1. The drain pipe of the water pump 41 extends into the municipal drainage ditch. The underground protective pool 42 plays a protective role and provides installation space for the water pump 41.
[0023] An elastic limiting strip 6 is fixedly connected to the top of the upper waterproof pad 22, and there is a distance between the elastic limiting strip 6 and the edge of the upper waterproof pad 22. The elastic limiting strip 6 can play a shielding role. During construction, sealant is filled between the elastic limiting strip 6 and the concrete wall to seal the gap between the upper waterproof pad 22 and the concrete wall.
[0024] An air chamber 61 is provided inside the elastic limiting strip 6, and an air inflator 62 is fixedly connected to the top of the elastic limiting strip 6. After the filled sealant has solidified, air is inflated into the air chamber 61 through the air inflator 62 to compress the sealant and counteract the shrinkage of the concrete wall and the sealant in low temperature weather.
[0025] The working principle and usage process of this utility model are as follows: During construction, a trench is excavated at the construction location of the basement concrete wall. The seepage pool 1 is installed in the trench. Then, the lower waterproofing pad 2 is laid on the inclined inner wall of the foundation pit, with one end of the lower waterproofing pad 2 extending into the interior of the seepage pool 1. Then, the top permeable filter cloth 21 is fixedly connected to the inner wall of the lower waterproofing pad 2, and the top permeable filter cloth 21 is bent away from the basement concrete wall. Then, part of the inner supporting gravel 3 is laid inside the seepage pool 1 and on top of the lower waterproofing pad 2. Then, the upper waterproofing pad 22 is laid on top of the inner supporting gravel 3, and the bottom permeable filter cloth 23 is laid on top of the seepage pool 1. Then, soil is filled into the foundation pit inside the upper waterproofing pad 22. Then, the top of the upper waterproofing pad 22 is laid on top of the soil, and the remaining... The inner supporting crushed stone 3 is laid on top of the upper waterproof pad 22. The bottom opening cleaning pipe 5 is buried in the inner supporting crushed stone 3. Then, the top permeable filter cloth 21 is covered on top of the inner supporting crushed stone 3. The water injection pipe 51 extends upward through the top permeable filter cloth 21. Then, soil is laid on top of the top permeable filter cloth 21 to fill and level the foundation pit. After the construction is completed, the lower waterproof pad 2, the top permeable filter cloth 21, the upper waterproof pad 22 and the inner supporting crushed stone 3 work together to form a water seepage channel away from the basement concrete wall. The water seeps into the inner supporting crushed stone 3 through the top permeable filter cloth 21 and is guided downward by the lower waterproof pad 2 and the upper waterproof pad 22. During the seepage process, it will not come into contact with the basement concrete wall. After the water enters the seepage pool 1, it is pumped out and discharged by the pumping channel 4.
