Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and in particular to a foundation pit anti-seepage reinforcement device. Background Technology

[0002] To meet the demands of intensive urban development, new buildings and transportation facilities, such as commercial complexes, transfer hubs, or underground parking lots, must be located adjacent to existing subway stations to improve land utilization. All of these projects require excavation of foundation pits near existing subway stations. During construction, the normal operation of the subway can cause minor disturbances or even deformation to the foundation pits, necessitating reinforcement and support.

[0003] A related technology discloses a stabilizing structure for inclined support of an excavation pit, including a support plate and at least one support mechanism. The support plate is vertically arranged and used to abut against the sidewall of the excavation pit. The support mechanism includes a first base, a second base, and an inclined support rod. The first base is fixed to the bottom of the excavation pit, the second base is located on the upper part of the support plate, and the two ends of the inclined support rod are respectively connected to the first base and the second base to support the vertical arrangement of the support plate.

[0004] However, the support mechanism of the aforementioned stabilizing structure is fixed relative to the support plate, and the support point of the mechanism cannot be changed according to the different reinforcement requirements of the pit sidewall. This leads to a mismatch between the pressure on the pit sidewall and the supporting force it provides to the pit sidewall in some application scenarios, ultimately causing deformation of the pit and affecting the quality and safety of the pit construction.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1-3As shown, this utility model provides a foundation pit anti-seepage reinforcement device, including a supporting base plate 1, supporting side plates 2, and supporting components 3. The supporting base plate 1 is horizontally arranged, and a first mounting member 11 is provided on the upper surface of the supporting base plate 1. The position of the first mounting member 11 is adjustable along a first direction (X direction in the figure). The supporting side plates 2 and the supporting base plate 1 are arranged at right angles, that is, the supporting side plates 2 and the supporting base plate 1 are "L" shaped. A second mounting member 21 is provided on the side of the supporting side plate 2 that is closer to the supporting base plate 1 in the horizontal direction. The position of the second mounting member 21 is adjustable in the vertical direction. A waterproof layer 22 is provided on the side of the supporting side plate 2 that is away from the supporting base plate 1 in the horizontal direction. The supporting components 3 include a first connecting member 31, a second connecting member 32, and a supporting member 33. The first connecting member 31 is connected to the first mounting member 11, and the second connecting member 32 is connected to the second mounting member 21. One end of the supporting member 33 is hinged to the first connecting member 31, and the other end is hinged to the second connecting member 32.

[0035] The supporting base plate 1 of the foundation pit anti-seepage reinforcement device is set in the soil layer at the bottom of the foundation pit, the supporting side plate 2 abuts against the side wall of the foundation pit, and the supporting component 3 is connected between the supporting base plate 1 and the supporting side plate 2, providing oblique support force for the supporting side plate 2, thereby forming support for the side wall of the foundation pit. The first mounting component 11 is adjustable in position along the first direction, the second mounting component 21 is adjustable in position along the vertical direction, and one end of the supporting component 33 is hinged to the first connecting component 31, and the other end is hinged to the second connecting component 32. The foundation pit anti-seepage reinforcement device can adjust the position of the first mounting component 11 and the second mounting component 21 according to different reinforcement requirements of the foundation pit side wall, thereby adjusting the angle of the supporting component 3 and changing the support direction of the supporting component 3 on the supporting side plate 2. The waterproof layer 22 can effectively prevent leakage from the side wall of the foundation pit. This foundation pit anti-seepage reinforcement device can improve the support effect on the foundation pit sidewall by changing the support direction of the support component 3 on the support side plate 2, effectively control the deformation of the foundation pit sidewall, reduce foundation pit leakage, avoid settlement of existing stations due to foundation pit deformation, improve the quality of engineering construction, and the foundation pit anti-seepage reinforcement device is easy to operate and has good versatility.

[0036] Optionally, such as Figure 2 As shown, the support base plate 1 has multiple sets of first mounting holes 12 spaced apart along a first direction. A first mounting member 11 can be detachably connected to the support base plate 1 through one of the first mounting hole sets 12. Specifically, the first mounting member 11 is provided with bolts or pins. The first mounting member 11 is inserted into one of the first mounting hole sets 12 by bolts or pins, thereby detachably connecting the first mounting member 11 to the support base plate 1. The first mounting member 11 can be detachably connected to the support base plate 1 through different sets of first mounting holes 12, thereby achieving position adjustment of the first mounting member 11 along the first direction.

[0037] Furthermore, such as Figure 2As shown, the first mounting hole group 12 includes a first mounting hole 121 and a second mounting hole 122, the second mounting hole 122 being an elongated hole. The first mounting hole 121 and the second mounting hole 122 are spaced apart along a second direction (Y direction in the figure), the second direction being a direction perpendicular to the first direction in the horizontal plane. By setting the first mounting hole 121 and the second mounting hole 122, the first mounting component 11 is mounted on the support base plate 1 through the two mounting holes, further improving the installation stability of the first mounting component 11, and thus improving the installation stability of the support assembly 3. Setting the second mounting hole 122 as an elongated hole can effectively prevent the first mounting component 11 from being unable to be smoothly installed on the support base plate 1 due to deformation.

[0038] Optionally, such as Figure 2 As shown, the first mounting member 11 has a plurality of first connecting holes 111 spaced apart along the second direction. The first connecting member 31 can be detachably connected to the first mounting member 11 through one of the first connecting holes 111. Specifically, the first connecting member 31 is provided with a bolt or pin, which can be inserted into one of the first connecting holes 111 to detachably connect the first connecting member 31 and the first mounting member 11. By connecting the first connecting member 31 to different first connecting holes 111, the position of the first connecting member 31 in the second direction can be adjusted, thereby changing the support direction of the support assembly 3.

[0039] Similarly, such as Figure 3 As shown, the support side plate 2 has multiple sets of second mounting holes 23 spaced apart along the vertical direction. A second mounting member 21 can be detachably connected to the support side plate 2 through one of the sets of second mounting holes 23. Specifically, the second mounting member 21 is provided with bolts or pins. The second mounting member 21 is inserted into one of the sets of second mounting holes 23 by bolts or pins, thereby detachably connecting the second mounting member 21 to the support side plate 2. The second mounting member 21 can be detachably connected to the support side plate 2 through different sets of second mounting holes 23, thereby achieving vertical position adjustment of the second mounting member 21.

[0040] Furthermore, such as Figure 3 As shown, the second mounting hole group 23 includes a third mounting hole 231 and a fourth mounting hole 232, with the fourth mounting hole 232 being an elongated hole. The third mounting hole 231 and the fourth mounting hole 232 are spaced apart along a third direction (Z-direction in the figure), which is parallel to the second direction. By providing the third mounting hole 231 and the fourth mounting hole 232, the second mounting component 21 is mounted on the support side plate 2 through the two mounting holes, further improving the installation stability of the second mounting component 21, and consequently improving the installation stability of the support assembly 3. Setting the fourth mounting hole 232 as an elongated hole effectively prevents the second mounting component 21 from being unable to be smoothly installed on the support side plate 2 due to deformation.

[0041] Optionally, such as Figure 3 As shown, the second mounting member 21 has multiple second connecting holes 211 spaced apart along a third direction. The second connecting member 32 can be detachably connected to the second mounting member 21 through one of the second connecting holes 211. Specifically, the second connecting member 32 is provided with bolts or pins, which can be inserted into one of the second connecting holes 211 to detachably connect the second connecting member 32 and the second mounting member 21. By connecting the second connecting member 32 to different second connecting holes 211, the position of the second connecting member 32 in the third direction can be adjusted, thereby changing the support direction of the support assembly 3.

[0042] For example, such as Figure 2 and Figure 3 As shown, the first mounting member 11 has an upward-opening first limiting groove 112, and multiple first connecting holes 111 are spaced apart at the bottom of the first limiting groove 112. The second mounting member 21 has a second limiting groove 212 with its opening facing the side of the horizontal direction close to the support base plate 1, and multiple second connecting holes 211 are spaced apart at the bottom of the second limiting groove 212. The first connecting member 31 can be inserted into the first limiting groove 112, thereby further enhancing the limiting effect on the first connecting member 31 and improving the installation stability of the support assembly 3. The second connecting member 32 can be inserted into the second limiting groove 212, thereby further enhancing the limiting effect on the second connecting member 32 and improving the installation stability of the support assembly 3.

[0043] Optionally, such as Figure 4 and Figure 5 As shown, a first insertion structure 13 is provided on one side of the supporting base plate 1, and a second insertion structure 24 is provided on the bottom of the supporting side plate 2. The supporting base plate 1 and the supporting side plate 2 are fixed together by the first insertion structure 13 and the second insertion structure 24. After the foundation pit seepage prevention reinforcement device is used, the supporting base plate 1 and the supporting side plate 2 can be disassembled, which facilitates the transportation and storage of the foundation pit seepage prevention reinforcement device. Moreover, the first insertion structure 13 and the second insertion structure 24 ensure the connection stability of the supporting base plate 1 and the supporting side plate 2. In this embodiment, the first insertion structure 13 and the second insertion structure 24 are mutually cooperating concave-convex insertion structures. In other embodiments, the first insertion structure 13 and the second insertion structure 24 can also be a slot-and-plate mating structure, which is not specifically limited here.

[0044] Optionally, such as Figure 1 or Figure 3As shown, a fixing cone 14 is also provided on the lower surface of the supporting base plate 1, and multiple fixing cones 14 can be provided. The fixing cone 14 is a sharp conical structure and can be connected to the supporting base plate 1 by welding, bolting, or integral molding. The fixing cone 14 can be inserted into the soil layer at the bottom of the foundation pit, and prevents the supporting base plate 1 from sliding horizontally or overturning through mechanical interlocking, which significantly improves the displacement resistance of the foundation pit anti-seepage reinforcement device, especially in soft soil or vibrating environments. It is suitable for sloping or uneven foundation pit bottoms. The insertion depth of the fixing cone 14 can be adjusted to adapt to the terrain, ensuring that the supporting base plate 1 is in close contact with the soil layer at the bottom of the foundation pit.
