Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a support system for large deep foundation pits. Background Technology

[0002] With the rapid advancement of urbanization, the development and utilization of underground space is attracting increasing attention. Deep foundation pit engineering mainly includes the design and construction of the deep foundation pit support system and earthwork excavation, and is a highly comprehensive system engineering project. A deep foundation pit is an earthen pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. The most crucial aspect of deep foundation pit engineering is the design and construction of the support system. Without a reliable support system, deep foundation pit excavation will inevitably affect adjacent buildings or structures, and in severe cases, may even cause accidents such as ground subsidence and structural collapse.

[0003] Utility model patent CN214783978U discloses a large-scale deep foundation pit support structure, including a top plate and a bottom plate connected to the lower surface of the top plate. The bottom plate is provided with a fixing mechanism for fixing the bottom plate, and the top plate is provided with a support mechanism for abutting against the side wall of the wall. The support mechanism includes a support block provided on the upper surface of the top plate. A telescopic member that can rotate in the vertical direction is hinged to the support block. A protective plate for supporting the wall is detachably connected to the end of the telescopic member. A plug rod that can be inserted into the ground is fixed on the lower surface of the protective plate.

[0004] The aforementioned large-scale deep foundation pit support structure is relatively complex and not quick or convenient to use, which reduces its applicability. Utility Model Content

[0005] To address the aforementioned issues, this application provides a support system for large-scale deep foundation pits.

[0006] The technical solution for a large-scale deep foundation pit support system provided in this application is as follows:

[0007] A large deep foundation pit support system includes a fixed plate. The upper surface of the fixed plate is provided with a support assembly for supporting the foundation pit and a fixing assembly for fixing the fixed plate. The support assembly includes two fixing blocks fixedly connected to both sides of one end of the upper surface of the fixed plate. A fixing rod is fixedly connected between the fixing blocks. A protective plate is sleeved on the fixing rod. Two telescopic support rods are hinged to the side wall of the protective plate near the fixed plate. Each telescopic support rod has a through hole on the side wall away from the protective plate. The upper surface of the fixed plate has two receiving grooves adapted to the telescopic support rods. A pin is provided on one side of the fixed plate, and the pin passes through the fixed plate and through the through hole.

[0008] By adopting the above technical solution, when using it, the fixing plate is placed on one side of the wall that needs to be supported, and then the guard plate is swung to make it stand up and fit against the side wall. Then, one end of the telescopic support rod is moved to the end of the receiving groove away from the guard plate. By passing the pin through the fixing plate and the through hole, the telescopic support rod is fixed in the receiving groove to support the guard plate. This avoids the problem of the structure being too complicated and not quick and convenient to use, which would reduce its applicability.

[0009] Preferably, the fixing component includes a plurality of mounting holes formed on the upper surface of the fixing plate, each mounting hole being provided with a conical fixing post, and a limiting plate being fixedly connected to the top of the conical fixing post.

[0010] By adopting the above technical solution, after placing the fixing plate on one side of the wall and erecting the guard plate, the tapered fixing stake is inserted into the installation hole and driven into the ground with the help of the limiting plate, so that the limiting plate fits against the upper surface of the fixing plate, making it easy to fix the fixing plate to the ground.

[0011] Preferably, the lower surface of the limiting plate has multiple slots for pulling out the conical fixing pile.

[0012] By adopting the above technical solution, the limiting plate can be easily pried or pulled up through the slot, preventing the limiting plate from sticking to the fixing plate and making it difficult to pull the conical fixing pile out of the ground, which increases the difficulty of disassembly.

[0013] Preferably, the upper surface of the fixing plate is provided with a placement groove for storing the conical fixing pile between the two receiving grooves.

[0014] By adopting the above technical solution, after the conical fixing pile is disassembled, it can be conveniently stored in the placement slot, avoiding the loss of the conical fixing pile and the fixing plate due to separate storage.

[0015] Preferably, one end of the fixing plate is fixedly connected to two connecting blocks, and one end of the guard plate is fixedly connected to two L-shaped connecting plates. The L-shaped connecting plates are located on one side of the connecting blocks, and each of the L-shaped connecting plates and one side wall of the connecting blocks has a connecting hole adapted to the pin.

[0016] By adopting the above technical solution, after the fixed plate is detached from the ground, the pin is pulled out, and then the guard plate is swung to make the guard plate fit with the fixed plate. The telescopic support rod is moved into the receiving groove, and then the pin is inserted into the L-shaped connecting plate and the connecting block through the connecting hole to connect the connecting block and the L-shaped connecting plate. This prevents the guard plate from swinging on the fixed plate during transportation, and at the same time, the pin makes it easy to lift the guard plate and the fixed plate for transportation.

[0017] Preferably, the upper surface of the fixing plate is provided with two locking rods, the bottom ends of which penetrate the fixing plate and are respectively inserted into the two end side walls of the pin.

[0018] By adopting the above technical solution, after inserting the pin into the fixing plate to fix the telescopic support rod, inserting the locking rod into the fixing plate so that one end of the locking rod is connected to the pin can prevent the pin from moving during use and causing the pin to detach from the fixing plate.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. This application utilizes the cooperative arrangement of structures such as a protective plate, a telescopic support rod, and a pin. In use, the fixed plate is placed on one side of the wall that needs support, and then the protective plate is swung to stand it upright and fit against the side wall. Then, one end of the telescopic support rod is moved into the receiving groove at the end away from the protective plate. By passing the pin through the fixed plate and the through hole, the telescopic support rod is fixed in the receiving groove to support the protective plate. This avoids the problem of a complex structure that is not quick and convenient to use, which would reduce its applicability.

[0021] 2. After detaching the fixed plate from the ground, pull out the pin, then swing the guard plate to make it fit against the fixed plate. Move the telescopic support rod into the receiving groove, and then insert the pin through the connecting hole into the L-shaped connecting plate and the connecting block to connect the connecting block and the L-shaped connecting plate. This prevents the guard plate from swinging on the fixed plate during transportation, and at the same time, the pin makes it easy to lift the guard plate and the fixed plate for transportation.

[0027] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0028] This application discloses a support system for large deep foundation pits.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A large deep foundation pit support system includes a fixed plate 1. The upper surface of the fixed plate 1 is provided with a support component for supporting the foundation pit and a fixing component for fixing the fixed plate 1. The support component includes a fixed block 2, a fixed rod 3, a protective plate 4, a telescopic support rod 5, a through hole 6, a receiving groove 7, and a pin 8.

[0030] Two fixing blocks 2 are provided, which are respectively fixedly connected to one side of the upper surface of the fixing plate 1. The fixing rod 3 is fixedly connected between the two fixing blocks 2. One end of the guard plate 4 is sleeved on the fixing rod 3. Two telescopic support rods 5 are provided, which are both hinged to the side wall of the guard plate 4 near the fixing plate 1. Two through holes 6 are provided, which are respectively opened on the side wall of the telescopic support rod 5 away from the guard plate 4. Two receiving grooves 7 are provided, which are both opened on the upper surface of the fixing plate 1 and are adapted to the telescopic support rod 5 respectively, for accommodating the telescopic support rod 5. The pin 8 is provided on one side of the fixing plate 1. The pin 8 passes through the fixing plate 1 and through the through hole 6, for fixing the telescopic support rod 5 in the receiving groove 7.

[0031] Reference Figure 1 and Figure 2 The fixing component includes multiple mounting holes 9 formed on the upper surface of the fixing plate 1. Each mounting hole 9 is provided with a conical fixing post 10. The top of the conical fixing post 10 is fixedly connected to a limiting plate 11. After the fixing plate 1 is placed on one side of the wall and the guard plate 4 is erected, the conical fixing post 10 is inserted into the mounting hole 9 and driven into the ground with the limiting plate 11, so that the limiting plate 11 fits against the upper surface of the fixing plate 1, making it easy to fix the fixing plate 1 on the ground.

[0032] Reference Figure 2 and Figure 4 The lower surface of the limiting plate 11 has multiple slots 12 for pulling out the conical fixing stake 10. The limiting plate 11 can be easily pried or pulled up through the slots 12 to prevent the limiting plate 11 from sticking to the fixing plate 1, making it difficult to pull the conical fixing stake 10 out of the ground, thus increasing the difficulty of disassembly.

[0033] Reference Figure 2The upper surface of the fixing plate 1 is provided with a placement groove 13 between the two receiving grooves 7 for storing the conical fixing pile 10. After the conical fixing pile 10 is disassembled, it can be conveniently stored through the placement groove 13 to avoid the conical fixing pile 10 being stored separately from the fixing plate 1 and thus being lost.

[0034] Reference Figure 1 and Figure 2 Two connecting blocks 14 are fixedly connected to one end of the fixed plate 1, and two L-shaped connecting plates 15 are fixedly connected to one end of the guard plate 4. The L-shaped connecting plates 15 are located on one side of the connecting blocks 14. The side walls of the L-shaped connecting plates 15 and the connecting blocks 14 are provided with connecting holes 16 that are compatible with the pins 8. After the fixed plate 1 is detached from the ground, the pins 8 are pulled out, and then the guard plate 4 is swung to make the guard plate 4 fit with the fixed plate 1. The telescopic support rod 5 is moved into the receiving groove 7, and then the pins 8 are inserted into the L-shaped connecting plates 15 and the connecting blocks 14 through the connecting holes 16 to connect the connecting blocks 14 and the L-shaped connecting plates 15. This prevents the guard plate 4 from swinging on the fixed plate 1 during transportation. At the same time, the pins 8 facilitate the lifting of the guard plate 4 and the fixed plate 1 for transportation.

[0035] Reference Figure 2 The upper surface of the fixing plate 1 is provided with two locking rods 17. The bottom ends of the locking rods 17 penetrate the fixing plate 1 and are respectively inserted into the side walls of the two ends of the pin 8. After the pin 8 is inserted into the fixing plate 1 to fix the telescopic support rod 5, the locking rods 17 are inserted into the fixing plate 1 so that one end of the locking rods 17 is inserted into the pin 8. This can prevent the pin 8 from moving during use and causing the pin 8 to detach from the fixing plate 1.

[0036] The implementation principle of a large-scale deep foundation pit support system according to an embodiment of this application is as follows: In use, the fixing plate 1 is placed on one side of the wall to be supported, and then the guard plate 4 is swung to make the guard plate 4 stand upright and fit against the side wall of the wall. After the guard plate 4 is erected, the conical fixing pile 10 is inserted into the installation hole 9, and the conical fixing pile 10 is driven into the ground with the limiting plate 11, so that the limiting plate 11 fits against the upper surface of the fixing plate 1, and the fixing plate 1 is fixed on the ground. Then, one end of the telescopic support rod 5 is moved to the end of the receiving groove 7 away from the guard plate 4, and the telescopic support rod 5 is fixed in the receiving groove by passing the pin 8 through the fixing plate 1 and the through hole 6. Inside 7, the protective plate 4 is supported, and after the fixed plate 1 is detached from the ground, the pin 8 is pulled out, and then the protective plate 4 is swung to make the protective plate 4 fit with the fixed plate 1. The telescopic support rod 5 is moved into the receiving groove 7, and then the pin 8 is inserted into the L-shaped connecting plate 15 and the connecting block 14 through the connecting hole 16 to connect the connecting block 14 and the L-shaped connecting plate 15. This prevents the protective plate 4 from swinging on the fixed plate 1 during transportation. At the same time, the pin 8 makes it easy to lift the protective plate 4 and the fixed plate 1 for transportation. This avoids the problem that the structure is too complicated and not quick and convenient to use, which would reduce the applicability.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
