Description

Technical Field

[0001] This utility model relates to the field of foundation pit construction technology, and in particular to a reusable foundation pit slope support mechanism. Background Technology

[0002] Foundation pit slope protection mechanisms are temporary structural facilities used in earthwork excavation processes such as building construction and municipal engineering to support and stabilize the soil on the side walls of foundation pits, preventing them from collapsing or sliding, thereby ensuring construction safety within the foundation pit and protecting the surrounding environment and buildings. They balance the lateral pressure of the soil itself by applying a counterforce and are an indispensable key technical means for underground space development.

[0003] Currently, traditional support components such as wooden formwork are commonly used in foundation pit support engineering. However, after completing their service mission, wooden formwork is either permanently buried underground or needs to be dismantled by breaking it up. This not only causes a large waste of wood but also generates a huge amount of construction waste, which is inconsistent with the environmental protection concept of green and sustainable development. Furthermore, its single-use nature makes it impossible to spread the project cost through reuse, resulting in low economic benefits. In view of this, this application proposes a reusable foundation pit slope support mechanism based on the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a reusable foundation pit slope support mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reusable foundation pit slope support mechanism includes two first baffles. A fixing cylinder is fixedly installed on the inner side of the first baffle, and a connecting cylinder is sleeved between the fixing cylinders. A connecting shaft is welded to both sides of the first baffle. A reinforcing screw is threaded into the connecting shaft. A connecting block is rotatably installed on the outside of the connecting shaft. A second baffle is fixedly installed between the connecting blocks. The connecting block is located between the reinforcing screw and the second baffle. A fixing rod is fixedly installed on the upper surface of the second baffle. A connecting ring is fixedly installed on the inner side of the first baffle. An iron chain is sleeved on the fixing rod. A hook is welded to one end of the iron chain. The hook is detachably engaged with the connecting ring. A ball is provided between the second baffle and the first baffle.

[0007] Furthermore, a fixing block is fixedly installed on the upper surface of the first baffle, and a lifting ring is fixedly installed on the fixing block.

[0008] Furthermore, the fixed cylinder is provided with a number of connecting holes arranged in a straight line, and a plug is inserted into the connecting cylinder, with one end of the plug passing through the connecting hole and extending to the bottom of the fixed cylinder.

[0009] Furthermore, the insertion rod has an oblique hole near its bottom, and a limiting rod is inserted into the oblique hole.

[0010] Furthermore, the bottom of the first baffle is configured as a right-angled trapezoid and the side away from the pit slope is a slope.

[0011] Furthermore, the number of fixed cylinders is set to four and distributed at the four corners of the first baffle.

[0012] Furthermore, pads are fixedly installed on both the outer side of the first baffle and the inner side of the second baffle, and the sphere is located between the pads.

[0013] Furthermore, the connecting block is provided with a shaft hole that fits with the connecting shaft with a clearance, and the end of the reinforcing screw is pressed against the inner wall of the connecting shaft to achieve locking.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model features a first baffle and a second baffle. The second baffle is rotatably mounted on both sides of the first baffle via connecting shafts. When facing a vertical slope, the second baffle remains coplanar with the first baffle. When supporting a sloping slope, the hook is removed from the connecting ring, and the second baffle is gently pushed. Under its own weight, the second baffle flips to the required angle and fits against the sloping slope. At this time, a sphere is placed between the first and second baffles, effectively preventing the second baffle from rotating. The overall device is simple and easy to operate, and can easily switch support modes for slopes of different angles.

[0016] 2. This utility model, by setting a fixed cylinder and a connecting cylinder, forms a telescopic sleeve structure with the fixed cylinder and connecting cylinder distributed inside the first baffle to adapt to foundation pits of different widths. By inserting the insertion rod into the different connecting holes arranged in a straight line on the fixed cylinder, the distance between the first baffles can be changed.

[0017] 3. By setting up pads, the ball is placed between the pads, which helps to increase friction and prevents rolling or displacement under vibration load. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4 A reusable foundation pit slope support mechanism includes two first baffles 1. A fixing cylinder 2 is fixedly installed on the inner side of the first baffle 1. A connecting cylinder 3 is sleeved between the fixing cylinders 2. A connecting shaft 4 is welded to both the left and right sides of the first baffle 1. A reinforcing screw 5 is internally threaded onto the connecting shaft 4. A connecting block 6 is rotatably installed on the outside of the connecting shaft 4. A second baffle 7 is fixedly installed between the connecting blocks 6. The connecting block 6 is located between the reinforcing screw 5 and the second baffle 7. A fixing rod 20 is fixedly installed on the upper surface of the second baffle 7. A connecting ring 8 is fixedly installed on the inner side of the first baffle 1. An iron chain 9 is sleeved on the fixing rod 20. A hook 10 is welded to one end of the iron chain 9. The hook 10 is detachably snapped onto the connecting ring 8. A ball 11 is provided between the second baffle 7 and the first baffle 1.

[0028] To achieve adaptive support for slopes with different gradients, second baffles 7 are rotatably installed on both sides of the first baffle 1 via connecting shafts 4. When facing a vertical slope, the second baffle 7 remains coplanar with the first baffle 1. When it is necessary to support a sloping slope, the hook 10 is removed from the connecting ring 8, and the second baffle 7 is gently pushed. Under its own weight, the second baffle 7 flips to the required angle and fits against the sloping slope. At this time, the sphere 11 is placed between the first baffle 1 and the second baffle 7, effectively preventing the second baffle 7 from rotating. The overall device is simple and easy to operate, and can easily switch the support mode for slopes with different angles.

[0029] Reference Figure 2-3 Specifically: a fixing block 12 is fixedly installed on the upper surface of the first baffle 1, and a lifting ring 13 is fixedly installed on the fixing block 12. The lifting ring 13 provides a force point for the overall hoisting.

[0030] Reference Figure 3 , Figure 5 Specifically: the fixed cylinder 2 is provided with a number of connecting holes 14 arranged in a straight line, and the connecting cylinder 3 is provided with a rod 15, one end of the rod 15 passing through the connecting hole 14 and extending to the bottom of the fixed cylinder 2;

[0031] To accommodate pits of different widths, the fixed cylinder 2 and the connecting cylinder 3 distributed inside the first baffle 1 form a telescopic sleeve structure. By inserting the insert rod 15 into the different connecting holes 14 arranged in a straight line on the fixed cylinder 2, the distance between the first baffles 1 can be changed.

[0032] Reference Figure 5-7 Specifically: the insertion rod 15 is provided with an oblique hole 16 near the bottom, and a limiting rod 17 is inserted into the oblique hole 16;

[0033] By inserting the limiting rod 17 into the oblique hole 16 of the insert rod 15 for anti-loosening fixation, the distance between the two first baffles 1 can be quickly and reliably adjusted and locked.

[0034] Reference Figure 1 Specifically: the bottom of the first baffle 1 is set in the shape of a right-angled trapezoid and the side away from the slope of the foundation pit is a slope;

[0035] The first baffle 1 has a right-angled trapezoidal design at the bottom and a sloping side away from the slope, which facilitates demolding and recycling after construction and makes it easier to provide installation space for cement pipes and other components in the foundation pit.

[0036] Reference Figure 5 Specifically, the number of fixed cylinders 2 is set to four and distributed at the four corners of the first baffle 1.

[0037] Reference Figure 4 , Figure 6Specifically: pads 18 are fixedly installed on the outer side of the first baffle 1 and the inner side of the second baffle 7, and the sphere 11 is located between the pads 18;

[0038] The ball 11 is placed between the pads 18 to improve friction and prevent rolling or displacement under vibration load.

[0039] Reference Figure 5-6 Specifically: the connecting block 6 is provided with a shaft hole 19 that fits with the connecting shaft 4 with a clearance, and the end of the reinforcing screw 5 is pressed against the inner wall of the connecting shaft 4 to achieve locking.

[0040] Working principle: To achieve adaptive support for slopes with different gradients, second baffles 7 are rotatably installed on both sides of the first baffle 1 via connecting shafts 4. When facing a vertical slope, the second baffle 7 remains coplanar with the first baffle 1. When it is necessary to support a sloping slope, the hook 10 is removed from the connecting ring 8, and the second baffle 7 is gently pushed. The second baffle 7 flips to the required angle under its own weight and fits against the sloping slope. At this time, the sphere 11 is placed between the first baffle 1 and the second baffle 7, effectively preventing the second baffle 7 from rotating. The whole device is simple and easy to operate, and can easily switch the support mode for slopes with different angles.

[0041] To accommodate pits of different widths, the fixed cylinder 2 and the connecting cylinder 3 distributed inside the first baffle 1 form a telescopic sleeve structure. By inserting the rod 15 into the different connecting holes 14 arranged in a straight line on the fixed cylinder 2, the distance between the first baffles 1 can be changed.

[0042] By inserting the limiting rod 17 into the oblique hole 16 of the insert rod 15 for anti-loosening fixation, the distance between the two first baffles 1 can be quickly and reliably adjusted and locked.

[0043] The first baffle 1 has a right-angled trapezoidal design at the bottom and a sloping side away from the slope, which facilitates demolding and recycling after construction and makes it easier to provide installation space for cement pipes and other components in the foundation pit.

[0044] The lifting ring 13 provides a force-bearing point for the overall hoisting, and the ball 11 is placed between the pads 18 to improve friction and prevent rolling or displacement under vibration load.
