Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a foundation pit anti-collapse support structure for geotechnical engineering. Background Technology

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, a large number of high-rise buildings, underground transportation hubs, underground commercial facilities and other engineering projects are emerging. These projects often require large-scale foundation pit excavation, and the requirements for the depth, size and stability of the foundation pits are becoming increasingly stringent.

[0003] In existing technologies, protective plates are mostly installed on the pit walls for protection and support. However, when the terrain around the pit has a steep slope and a large elevation difference, the rocks and soil have greater potential energy under the action of gravity, resulting in poor stability and a tendency to slide and collapse, forming falling rocks that may damage the equipment. Existing technologies also install baffles on top of the protective plates for protection. When falling rocks hit the baffles, they will generate impact force on the device. Without buffer components, the support structure may be damaged over time. Therefore, we propose a geotechnical engineering foundation pit anti-collapse support structure. Utility Model Content

[0004] The purpose of this utility model is to provide a support structure for preventing the collapse of foundation pits in geotechnical engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a geotechnical engineering foundation pit anti-collapse support structure, comprising a first protective plate and a second protective plate;

[0006] A buffer assembly is placed on a first protective plate. The buffer assembly includes a support rod disposed on the first protective plate. An extension plate is disposed at the bottom of the first protective plate. A first sliding groove is opened at the top of the extension plate. A slider is slidably connected in the first sliding groove. The side of the support rod away from the first protective plate is fixedly connected to the slider. A spring is fixedly connected between the slider and the first sliding groove. The spring is provided with damping.

[0007] A protective component is placed on a first protective plate. The protective component includes a baffle that is rotatably connected to the first protective plate. Two baffles are provided. A support plate is provided on both the first and second protective plates. A spring is provided on the top of the support plate. The side of the spring away from the support plate is fixedly connected to the bottom of the baffle.

[0008] Furthermore, a fixed plate is rotatably connected to the first protective plate, and both baffles are slidably connected within the fixed plate. A second rotating shaft is rotatably connected between the first protective plate and the second protective plate.

[0009] The above technical solution allows for the fine adjustment of the two protective plates according to the different shapes of the pit walls by setting a second rotating shaft. The setting of the fixed plate allows the baffles on both sides to change position by following the protective plates.

[0010] Furthermore, both the first and second protective plates are provided with limiting components. The limiting components include a first rotating shaft with a torsion spring on it. The first and second protective plates are provided with slots on the side near the first rotating shaft. The bottom of the torsion spring is rotatably connected to the limiting plate, and the extension plate is located at the top of the limiting plate.

[0011] By adopting the above technical solution, by setting a limiting component, the side of the extension plate closest to the protective plate can be limited and fixed to connect with the protective plate.

[0012] Furthermore, a connecting assembly is provided on the side of the first protective plate near the support rod. The connecting assembly includes a connecting plate, the support rod is fixedly connected to the connecting plate, and a bolt is threadedly connected between the connecting plate and the first protective plate.

[0013] The above technical solution involves setting up a connecting component to connect the buffer component to the protective plate, which facilitates disassembly and installation.

[0014] Furthermore, the first protective plate is provided with a splicing assembly, which includes a plug rod that is slidably connected to the first protective plate, and the second protective plate has a socket on the side away from the first protective plate.

[0015] The above technical solution allows for the easy splicing of multiple support structures by setting up splicing components, and also facilitates disassembly.

[0016] Furthermore, a second groove is provided on the side of the first protective plate near the insertion rod, and a handle is slidably connected in the second groove, the handle being fixedly connected to the insertion rod.

[0017] The above technical solution allows for the retraction and removal of the insertion rod by pulling the handle, through the setting of a handle and the opening of a second sliding groove.

[0018] Furthermore, both the first and second protective plates are provided with second rivets, and the bottom of the extension plate is provided with a first rivet.

[0019] The above technical solution is adopted: a first rivet is used to fix the extension plate to the foundation, and a second rivet is used to fix the protective plate to the pit wall.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting up protective components, damage to the device from falling rocks during excavation can be prevented. The buffer components can absorb the impact force of falling rocks hitting the top of the baffle on the device, thereby extending the service life of the device. This solves the problem that in the prior art, most protective plates are set up on the pit wall for protection and support. However, when the terrain around the pit has a steep slope and a large height difference, the rocks and soil have greater potential energy under gravity and poor stability, making them prone to sliding and collapse, which may damage the equipment. The prior art sets up a baffle on top of the protective plate for protection, but when falling rocks hit the baffle, they will generate impact force on the device. Without buffer components, the support structure may be damaged in the long run. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-3 As shown, this utility model provides a technical solution: a geotechnical engineering foundation pit anti-collapse support structure, comprising:

[0036] First protective plate 1, second protective plate 2;

[0037] A buffer assembly 3 is placed on a first protective plate 1. The buffer assembly 3 includes a support rod 31 set on the first protective plate 1. An extension plate 32 is set at the bottom of the first protective plate 1. A first groove 33 is opened at the top of the extension plate 32. A slider 34 is slidably connected in the first groove 33. The side of the support rod 31 away from the first protective plate 1 is fixedly connected to the slider 34. A spring 35 is fixedly connected between the slider 34 and the first groove 33. A damping 36 is set in the spring 35. A second rivet 9 is set on both the first protective plate 1 and the second protective plate 2. A first rivet 8 is set at the bottom of the extension plate 32.

[0038] The protective component 6 is placed on the first protective plate 1. The protective component 6 includes a baffle 61 rotatably connected to the first protective plate 1. There are two baffles 61. Support plates 64 are provided on both the first protective plate 1 and the second protective plate 2. A spring piece 63 is provided on the top of the support plate 64. The side of the spring piece 63 away from the support plate 64 is fixedly connected to the bottom of the baffle 61.

[0039] Specifically, the extension plate 32 is first inserted into the foundation using the first rivet 8. Then, the first protective plate 1 and the second protective plate 2 are fixed to the pit wall using the second rivet 9. When a rock falls, it will come into contact with the baffle 61, and the resulting impact will cause the spring 63 to be squeezed. Then, the baffle 61 will be reset and the rock will be bounced off. When the impact force on the baffle 61 is transmitted to the device, the support rod 31 will drive the slider 34 to slide in the first groove 33. Then, it will squeeze the spring 35 and the internal damper 36, thereby offsetting the potential energy generated by the impact force and extending the service life of the device.

[0040] Furthermore, such as Figure 2As shown: A fixed plate 62 is rotatably connected to the first protective plate 1, and two baffles 61 are slidably connected within the fixed plate 62. A second rotating shaft is rotatably connected between the first protective plate 1 and the second protective plate 2. By setting the second rotating shaft, the two protective plates can be finely adjusted according to the different shapes of the pit walls. The setting of the fixed plate 62 allows the baffles 61 on both sides to slide and change position within the fixed plate 62 following the position of the protective plates.

[0041] The above solutions also have the problem that multiple support structures cannot be spliced ​​together, such as... Figure 2 and Figure 3 As shown: A splicing assembly 5 is provided on the first protective plate 1. The splicing assembly 5 includes a plug rod 51, which is slidably connected to the first protective plate 1. A plug hole 54 is provided on the side of the second protective plate 2 away from the first protective plate 1. A second sliding groove 53 is provided on the side of the first protective plate 1 near the plug rod 51. A handle 52 is slidably connected in the second sliding groove 53. The handle 52 is fixedly connected to the plug rod 51. When splicing is required, the handle 52 is pulled through the second sliding groove 53 to pull out the plug rod 51 inside the first protective plate 1 and splice it into the plug hole 54 on the second protective plate 2 to complete the splicing. It is also convenient for disassembly.

[0042] The above solution also has the problem that the extension plate 32 cannot be connected to the protective plate, such as... Figure 4 As shown: Both the first protective plate 1 and the second protective plate 2 are provided with a limiting component 7. The limiting component 7 includes a first rotating shaft 71, on which a torsion spring 72 is provided. Both the first protective plate 1 and the second protective plate 2 are provided with a slot 73 on the side near the first rotating shaft 71. The bottom of the torsion spring 72 is rotatably connected to a limiting plate 74. An extension plate 32 is located on top of the limiting plate 74. The limiting plate 74 can be locked at the bottom of the extension plate 32 for limiting by the torsion spring 72, and it is easy to disassemble.

[0043] Furthermore, such as Figure 2 As shown: A connecting component 4 is provided on the side of the first protective plate 1 near the support rod 31. The connecting component 4 includes a connecting plate 41. The support rod 31 is fixedly connected to the connecting plate 41. A bolt 42 is threadedly connected between the connecting plate 41 and the first protective plate 1. By setting the connecting component 4, the buffer component 3 is connected to the protective plate, and it is convenient to disassemble and install.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
