Description

Technical Field

[0001] This utility model belongs to the field of building foundation pit technology, and in particular relates to a water-stopping and retaining structure for building foundation pits. Background Technology

[0002] In current construction foundation pit excavation projects, a continuous wall is generally constructed around the edge of the foundation pit using interlocking cement mixing piles or high-pressure jet grouting piles to act as a water-stopping curtain. The cement mixing piles or high-pressure jet grouting piles start from the ground and penetrate downwards into the low-permeability clay layer at the bottom of the foundation pit, creating an impermeable space inside the foundation pit.

[0003] Patent No. CN221855574U discloses a water-stopping enclosure structure for building foundation pits, including a water-stopping isolation cylinder. A base is fixedly fitted onto the water-stopping isolation cylinder, and a lifting groove is formed on the lower surface of the base. An installation plate is slidably connected to the inner wall of the lifting groove. The installation plate is fitted onto the water-stopping isolation cylinder and slidably connected. Multiple reinforcing ground nails are provided on the lower surface of the installation plate. A lifting assembly for lifting the installation plate is installed on the base. The lifting assembly includes a first threaded rod, a rotating block, and a guide rod. When the water-stopping isolation cylinder needs to be installed, the worker puts the lower end of the water-stopping isolation cylinder into the foundation pit, places the base on the ground, and then rotates the first threaded rod through the rotating block. Since the first threaded rod is threadedly connected to the base and the lower end of the first threaded rod is rotatably connected to the installation plate, the first threaded rod drives the installation plate to move downward, causing the reinforcing ground nails to insert into the ground, reducing the probability of the water-stopping isolation cylinder tilting and enhancing the stability of the base and the water-stopping isolation cylinder.

[0004] In the existing technology, by setting the first threaded rod and the base thread, the overall stability of the device is improved when the ground is uneven. However, the following problems still exist in the overall use: First, in the existing technology, when installing the water-stopping maintenance structure, in order to prevent the surrounding groundwater from seeping out, a water pipe is inserted into the ground to carry out water diversion and drainage work. However, the existing structure cannot utilize the water after diverting it, resulting in a waste of resources. Second, the water-stopping maintenance structure spliced ​​in the existing technology is not stable enough. After long-term use, it is easy to loosen and tilt, causing a risk of collapse.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1:

[0027] refer to Figure 1 and Figure 2 A foundation pit water-stopping and retaining structure includes water-stopping blocks 10. Connecting blocks 11 are provided at both ends of multiple water-stopping blocks 10. The connecting blocks 11 are generally L-shaped and used to connect the corners of the water-stopping blocks 10. One end of both the water-stopping blocks 10 and the connecting blocks 11 is provided with a protrusion 12, and the other end of both the water-stopping blocks 10 and the connecting blocks 11 is provided with a groove 13. The protrusion 12 and the groove 13 are slidably connected. The multiple water-stopping blocks 10 are divided into four groups, each group arranged in an array. The multiple groups of water-stopping blocks 10 are spliced ​​together by the protrusions 12 and grooves 13 at both ends, forming a square arrangement. Each of the 0 units is equipped with a water storage chamber 14, which is used to store the introduced groundwater for recycling. The groundwater inside the water storage chamber 14 will increase the weight, thereby improving the stability of the device. A water inlet pipe 17 is slidably installed inside one of the water stop blocks 10. A water outlet 27 is provided on the outer surface of the water inlet pipe 17. The water inlet pipe 17 is connected to the inside of the water storage chamber 14 through the water outlet 27. One end of the water inlet pipe 17 is closed, and the extended end of the water inlet pipe 17 is open to guide the groundwater and discharge the groundwater into the inside of the water storage chamber 14 through the water outlet 27.

[0028] Further reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Each of the multiple protrusions 12 and grooves 13 has a through hole 15 for water injection on its exterior. The through hole 15 is connected to the interior of the water storage cavity 14. By setting the through hole 15, the groundwater inside the water storage cavity 14 can be diverted to the interior of the adjacent water storage cavity 14, thereby increasing the weight of the adjacent water-stopping block 10 and improving the overall stability of the device. Each of the multiple protrusions 12 has a sealing strip 16 on its exterior. The sealing strip 16 has a connection hole corresponding to the through hole 15 inside. The sealing strip 16 is used to seal the connection between the protrusion 12 and the groove 13 to prevent groundwater from overflowing and seeping into the interior through the through hole 15, thereby improving the overall sealing performance of the device.

[0029] Further reference Figure 3 and Figure 4Multiple water-stop blocks 10 have slidably mounted insertion blocks 28 at their bottoms. These insertion blocks 28 extend outward through the water-stop blocks 10. Each insertion block 28 has multiple bolt holes 34 at one end, through which bolts can pass to fix the insertion block 28. The protruding end of the insertion block 28 is arc-shaped, making it easy to insert the protruding end of the insertion block 28 into the soil. The end face of the protruding end of the insertion block 28 has multiple sinking grooves 29, which increase the roughness of the insertion block 28 and improve the contact area between the insertion block 28 and the soil, thereby further improving the stability of the insertion block 28.

[0030] Further reference Figure 3 , Figure 4 and Figure 5 Each set of water-stopping blocks 10 has an external mounting block 19. Inside the mounting block 19, a drive gear 22 is rotatably mounted. A rack 18 is slidably mounted on the bottom of the drive gear 22. The drive gear 22 and the rack 18 are meshed and connected for transmission. The rack 18 is fixedly connected to the water pipe 17. A drive motor 21 is mounted on the outside of the mounting block 19 and the outside of the water-stopping block 10. The output end of the drive motor 21 is fixedly connected to the drive gear 22. By setting the drive gear 22, it can drive the rack 18 to extend outward when rotating, thereby driving the water pipe 17 to penetrate the soil, reducing manpower consumption and improving the installation efficiency of the water pipe 17.

[0031] Further reference Figure 3 , Figure 4 and Figure 5 The mounting block 19 has a rotatable locking block 20 inside. One end of the locking block 20 abuts against the outer surface of the drive gear 22. By setting the locking block 20, the rotation of the drive gear 22 can be restricted, preventing the water pipe 17 from being pushed by the mud and causing the drive gear 22 to damage the output shaft of the drive motor 21, thereby improving the service life of the device. A limit spring 201 is set on one side of the locking block 20. One end of the limit spring 201 is fixedly connected to the inner wall of the mounting block 19. By setting the limit spring 201, when the water pipe 17 pushes the drive gear 22 to rotate, the locking block 20 can be pushed to reset, so that the locking block 20 abuts against the surface of the drive gear 22.

[0032] Further reference Figure 3 , Figure 4 and Figure 5The mounting block 19 has a fixing block 23 inside, which is fixedly connected to the inner wall of the mounting block 19. The bottom of the fixing block 23 has a sleeve 24, which is hollow inside. The sleeve 24 has a return spring 25 inside, one end of which is fixedly connected to the inner wall of the sleeve 24. The other end of the return spring 25 has a cleaning block 26, which is slidably connected to the sleeve 24. One end of the cleaning block 26 abuts against the outer surface of the rack 18. One end of the cleaning block 26 has a pointed tip. By setting the pointed tip, the tooth grooves of the rack 18 can be cleaned to prevent dirt from clogging the surface of the rack 18 and affecting the meshing of the rack 18 with the drive gear 22, thereby improving the service life of the device.

[0033] Preferred, Reference Figure 1 Multiple support frames 30 are provided inside the multiple water-stop blocks 10. The support frames 30 are generally L-shaped and are used to abut against the connection between the water-stop blocks 10 and the connecting blocks 11. Multiple support seats 33 are provided at the bottom of the multiple support frames 30. The support seats 33 can support the support frames 30 and improve the stability of the device. One end of the multiple support frames 30 is provided with a compensation cylinder 31, and the other end of the multiple support frames 30 is provided with an abutment block 32. The output end of the compensation cylinder 31 abuts against the surface of the abutment block 32. By setting the compensation cylinder 31, the length of the support frame 30 can be compensated. After the support frame 30 is installed, by activating the compensation cylinder 31, the output end of the compensation cylinder 31 pushes the abutment block 32, so that the abutment block 32 drives the support frame 30 to fit tightly against the surface of the water-stop blocks 10, thereby improving the stability of the device.

[0034] In use, multiple water-stop blocks 10 are arranged in a square shape inside the foundation pit. During the arrangement, the protrusions 12 and grooves 13 are installed correspondingly, and a square space is formed by connecting blocks 11. Then, the support frame 30 is installed inside the water-stop block 10. The compensation cylinder 31 is activated, so that the output end of the multiple compensation cylinders 31 pushes the abutment block 32, so that the abutment block 32 drives the support frame 30 to abut against the outer surface, which provides support for the interior of the water-stop block 10. At the same time, the insertion block 28 is inserted into the bottom and extends outward, so that the protruding end of the insertion block 28 pierces into the surrounding soil, so that the soil pressure is on the end face of the protruding end of the insertion block 28, preventing the water-stop block 10 from tilting and further improving the stability of the device.

[0035] Then, the drive motor 21 is started, causing the output shaft of the drive motor 21 to drive the drive gear 22 to rotate. The drive gear 22 drives the rack 18 that meshes with it to move. The rack 18 drives the bottom water pipe 17 to move, causing the water pipe 17 to extend outward and penetrate the soil. During the movement of the water pipe 17, the bottom water outlet 27 faces the inside of the water storage chamber 14. The groundwater guided by the water pipe 17 flows into the inside of the water storage chamber 14 through the water outlet 27. Subsequently, the groundwater flows into the adjacent interior through the through hole 15 inside the water storage chamber 14, increasing its own weight and further improving the stability of the device. At the same time, it enables the recovery of groundwater.
