Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, and in particular to a seepage-proof retaining wall for foundation pit construction. Background Technology

[0002] During foundation pit construction, groundwater control and seepage prevention are crucial for ensuring project safety. Traditional foundation pit seepage prevention retaining walls often employ structural forms such as concrete gravity retaining walls, steel sheet piles, and diaphragm walls. While these methods can achieve support and waterproofing functions to a certain extent, they still face the following technical bottlenecks:

[0003] Most current seepage-proof retaining walls use sealing barriers, which means that although seepage at the edge of the foundation pit is blocked, the water is stored outside the retaining wall, leading to increased pressure and loosening of the layer at the edge of the foundation pit, thus affecting safety. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a seepage-proof retaining wall for foundation pit construction, which effectively solves the deficiencies of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: a seepage-proof retaining wall for foundation pit construction, including a water receiving trough, a fixed base plate fixedly connected to the bottom surface of the water receiving trough, a retaining wall fixedly connected to one edge of the fixed base plate, a plurality of insertion holes opened on the surface of the retaining wall, a connecting cylinder inserted into the inner wall of each of the insertion holes, a conical drilling cylinder fixedly connected to one end of the connecting cylinder, a plurality of water-permeable holes opened on the surface of the conical drilling cylinder, a spiral drilling blade fixedly connected to the outer wall of the conical drilling cylinder, a rotating head fixedly connected to the end of the connecting cylinder away from the conical drilling cylinder, sealing gaskets fixedly connected to the outer side and two sides of the retaining wall and the two sides of the water receiving trough, the rotating head having a hollow structure, the diameter of the inner wall of the rotating head matching the diameter of the inner wall of the connecting cylinder, and the diameter of the rotating head being larger than the diameter of the connecting cylinder.

[0006] Preferably, in any of the above schemes, a plurality of reinforcing support plates are fixedly connected to one side of the retaining wall near the water receiving trough, the bottom surfaces of the plurality of reinforcing support plates are fixedly connected to the bottom surface of the inner wall of the water receiving trough, and the bottom of the plurality of reinforcing support plates are provided with a connecting opening, and a connecting hole is provided in the middle of both sides of the water receiving trough, the connecting hole extending through the outside of the sealing gasket.

[0007] The technical effect achieved by adopting the above solution is that the connecting hole facilitates the left and right connection of adjacent water receiving tanks, and at the same time facilitates the connection of the drain pipe to release water flow.

[0008] Preferably, in any of the above embodiments, the bottom surface of the fixed base plate is fixedly connected with a plurality of anti-slip teeth, the length of the plurality of anti-slip teeth is adapted to the length of the fixed base plate, and the distribution width of the plurality of anti-slip teeth is adapted to the width of the water receiving trough.

[0009] The technical effects achieved by adopting the above solution are: the anti-slip teeth can be embedded in the ground to improve the anti-slip effect, and the anti-slip teeth can also create a wrinkle effect to improve the water resistance effect.

[0010] Preferably, in any of the above schemes, the side of the fixed base plate away from the retaining wall protrudes from the outside of the water receiving trough, and several anchor rods penetrate the side of the fixed base plate protruding from the outer wall of the water receiving trough.

[0011] The technical effect achieved by adopting the above solution is that the stability of the fixed base plate and the ground can be improved after the fixed base plate is fixed to the ground by several anchor rods.

[0012] Preferably, in any of the above schemes, the plurality of reinforcing support plates are located at the center between the plurality of insertion ports, and the height of the plurality of reinforcing support plates is adapted to the height of the retaining wall.

[0013] The technical effect achieved by adopting the above solution is to make the supporting force of the reinforcing support plate evenly distributed among several insertion ports, thereby improving the uniformity of the supporting force distribution.

[0014] This utility model has the following advantages:

[0015] 1. The seepage-proof retaining wall used in the construction of this foundation pit blocks and supports the side wall of the foundation pit. After being tightened, the sealing gasket can improve the sealing and water-proofing effect. The connecting cylinder is inserted through the insertion port, so that the conical drilling cylinder is inserted into the soil. This allows water in the soil layer to seep into the inside of the connecting cylinder through several permeable holes and be guided into the inside of the water collection tank. This releases the seeping water, prevents the soil moisture from becoming too high, improves the safety of the support and lifting, and the discharged water can be collected and discharged through the water collection tank to prevent it from entering the foundation pit.

[0016] 2. The seepage-proof retaining wall used in the construction of this foundation pit is drilled into the soil by rotating the auger drill bit. This allows the conical drill bit to easily drill into the soil, and after drilling, the auger drill bit can engage and fix the soil. At the same time, the rotating head blocks the retaining wall, allowing the conical drill bit to tighten and fix the retaining wall to the side wall of the foundation pit, thereby improving the stability of the connection and support.

Sealing gaskets 4 are fixedly connected to the outer side and both sides of the retaining wall 2 and the two sides of the water receiving trough 1. The rotating head 9 has a hollow structure. The diameter of the inner wall of the rotating head 9 is matched with the diameter of the inner wall of the connecting cylinder 15. The diameter of the rotating head 9 is larger than the diameter of the connecting cylinder 15.

[0023] As an optional technical solution of this utility model: a number of reinforcing support plates 12 are fixedly connected to one side of the retaining wall 2 near the water receiving trough 1. The bottom surface of the number of reinforcing support plates 12 is fixedly connected to the bottom surface of the inner wall of the water receiving trough 1. A connecting opening 13 is opened at the bottom of the number of reinforcing support plates 12. A connecting hole 5 is opened in the middle of both sides of the water receiving trough 1. The connecting hole 5 passes through the outside of the sealing gasket 4. The connecting hole 5 facilitates the left and right connection of adjacent water receiving troughs 1, and at the same time facilitates the connection of drainage pipe to release water flow.

[0024] As an optional technical solution of this utility model: a plurality of anti-slip teeth 3 are fixedly connected to the bottom surface of the fixed base plate 10. The length of the plurality of anti-slip teeth 3 is adapted to the length of the fixed base plate 10, and the distribution width of the plurality of anti-slip teeth 3 is adapted to the width of the water receiving groove 1. The plurality of anti-slip teeth 3 can be embedded in the ground to improve the anti-slip effect.

[0025] As an optional technical solution of this utility model: the fixed base plate 10 protrudes from the outside of the water receiving trough 1 on the side away from the retaining wall 2, and a number of anchor rods 11 are passed through the side of the fixed base plate 10 protruding from the outer wall of the water receiving trough 1.

[0026] As an optional technical solution of this utility model: several reinforcing support plates 12 are respectively located at the center between several insertion ports 14, and the height of the several reinforcing support plates 12 is adapted to the height of the retaining wall 2, so that the supporting force of the reinforcing support plates 12 is evenly distributed between several insertion ports 14, thereby improving the uniformity of the supporting force distribution.

[0027] The working process of this utility model is as follows: When the user uses it...

[0028] 1) The retaining wall 2 blocks and holds the side wall of the foundation pit, while the fixed base plate 10 is in contact with the bottom surface of the foundation pit. The fixed base plate 10 is pressed and fixed to the ground by the anchor rod 11.

[0029] 2) Then, the sealing gasket 4 can improve the sealing and waterproofing effect;

[0030] 3) Insert the connecting cylinder 15 through the insertion port 14, so that the conical drilling cylinder 6 is inserted into the soil, so that the water in the soil layer can penetrate into the interior of the connecting cylinder 15 through several water-permeable holes 8 and be guided into the interior of the water receiving tank 1, thereby releasing the permeated water. The discharged water can be collected and discharged through the water receiving tank 1 to prevent it from entering the foundation pit.

[0031] In summary, this utility model uses a retaining wall 2 to block and hold the foundation pit sidewall. After tightening, the sealing gasket 4 improves the sealing and water-proofing effect. The connecting cylinder 15 is inserted through the insertion port 14, allowing the conical drilling cylinder 6 to penetrate the soil. This allows water in the soil to seep into the connecting cylinder 15 through several permeable holes 8 and be guided into the water collection trough 1, releasing the seeped water and preventing excessive soil moisture, thus improving the safety of the support. The discharged water can be collected and discharged through the water collection trough 1, preventing it from entering the foundation pit. The spiral drilling blade 7 allows for easy drilling into the soil, facilitating the conical drilling cylinder 6. After drilling, the spiral drilling blade 7 engages and fixes with the soil. Simultaneously, the rotating head 9 blocks the retaining wall 2, allowing the conical drilling cylinder 6 to tighten and fix the retaining wall 2 to the foundation pit sidewall, improving the stability of the connection support.
