Description

Technical Field

[0001] This utility model is a foundation pit repair mechanism, belonging to the field of construction. Background Technology

[0002] During foundation pit construction, various problems such as slope instability and settlement may be encountered. If these problems are not addressed promptly, they will not only affect the project progress but may also pose a serious threat to the surrounding environment and buildings. Therefore, taking effective repair measures is crucial. When the foundation pit wall collapses, it needs to be backfilled and reinforced. Before backfilling, the foundation pit wall needs to be supported by protective plates. This involves connecting two parallel protective plates with multiple connecting pipes, making the protective plates fit snugly against the foundation pit wall. Under the protection of the protective plates, backfilling and compaction can be carried out in the collapsed area, thus repairing the foundation pit. Pipe joints need to be installed on the protective plates to connect the protective plates and connecting pipes with bolts. Currently, the pipe joints are fixed in the middle of one side of the protective plate, and the relative position of the protective plate and connecting pipes cannot be adjusted according to site requirements. This can easily lead to deformation of the upper part of the protective plate due to pressure from the backfill soil. Therefore, it is necessary to design a foundation pit repair mechanism that allows for adjustment of the relative position of the protective plates and connecting pipes as needed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foundation pit repair mechanism to solve the problems mentioned in the background technology. This utility model realizes the adjustment of the relative position of the guard plate and the connecting pipe as needed.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit repair mechanism, comprising two symmetrically arranged protective plates, with multiple horizontally arranged connecting pipes between the two protective plates. Adjacent connecting pipes are connected to each other by multiple sets of bolts. Each of the two protective plates has a pipe joint that mates with the connecting pipe on its opposite surface. One end of each connecting pipe is connected to the pipe joint by multiple sets of bolts. The outer surface of the pipe joint has vertically arranged through holes, into which studs are inserted. Both ends of the studs are fitted with lugs, and one end of each lug is connected to and fixed with a horizontal rib plate. The horizontal rib plate is connected and fixed to the protective plate. The upper and lower sides of the pipe joint are each provided with a first nut that is threadedly connected to the stud.

[0005] Furthermore, one end of the stud has a threaded blind hole, and the end of the stud away from the threaded blind hole is connected and fixed with a threaded head. The threaded head on one stud is threadedly connected to the threaded blind hole on another stud.

[0006] Furthermore, a circular hole is provided on the upper surface of the lug, the end of the stud passes through the circular hole, a second nut is provided on one side of the circular hole and is threadedly connected to the stud, and two transverse ribs on one of the guard plates are arranged between the two second nuts.

[0007] Furthermore, a support plate for limiting the position of the second nut is provided between the second nut and the lug. The end of the stud passes through the support plate. Two support plates on one of the guard plates are arranged between the two second nuts. Three support rods are installed on the side of the support plate facing the horizontal rib plate. The side of the horizontal rib plate facing the support plate and the side of the lug facing the support plate are both machined with positioning holes that cooperate with the corresponding support rods. The end of the support rod away from the support plate is inserted into the positioning hole.

[0008] Furthermore, multiple vertical stiffeners are provided between the two horizontal stiffeners, and the vertical stiffeners are welded and fixed to the guard plate.

[0009] Furthermore, multiple short stiffeners are installed on the opposite sides of both of the transverse stiffeners, and the short stiffeners are welded and fixed to the guard plate.

[0010] Furthermore, a protruding ring is provided on the side of the perforation facing the first nut. The protruding ring is arranged concentrically with the perforation and is connected and fixed to the pipe joint.

[0011] The beneficial effects of this utility model are:

[0012] 1. The threaded head of one stud is screwed into the threaded blind hole of another stud, and so on, to assemble multiple studs. When a stud is damaged, only the damaged stud needs to be replaced, which helps to reduce the cost of replacing parts.

[0013] 2. After the end of the stud passes through the round hole, screw on the second nut. The two second nuts cooperate with the two horizontal stiffeners to complete the assembly of the stud and the guard plate, which facilitates the assembly and disassembly of the stud and the guard plate.

[0014] 3. After the end of the stud passes through the support plate, tighten the second nut. With the support of the support plate and the support rod, there is a gap between the second nut and the horizontal stiffener. Therefore, when the second nut and the stud cannot be separated normally, the stud can be cut off using the gap between the support plate and the horizontal stiffener. After the cut-off stud is separated from another stud, the other studs can be reused.

[0015] 4. Pass the stud through the hole on the pipe joint, adjust the position of the pipe joint along the stud, and when the distance between the connecting pipe and the protective plate meets the requirements, use the two first nuts to restrict the relative position of the stud and the pipe joint, so as to adjust the relative position of the protective plate and the connecting pipe as needed.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a foundation pit repair mechanism, comprising two symmetrically arranged protective plates 1, with multiple horizontally arranged connecting pipes 8 between the two protective plates 1. Adjacent connecting pipes 8 are connected to each other by multiple sets of bolts. Each of the two protective plates 1 has a pipe joint 3 on its opposite side that mates with the connecting pipe 8. One end of the connecting pipe 8 is connected to the pipe joint 3 by multiple sets of bolts. The outer surface of the pipe joint 3 has vertically arranged through holes, into which studs 7 are inserted. The upper and lower sides of the pipe joint 3 are threaded to the studs 7. The first nut 12 allows the stud 7 to pass through the through hole on the pipe joint 3. The position of the pipe joint 3 is adjusted along the stud 7. When the distance between the connecting pipe 8 and the protective plate 1 meets the requirements, the two first nuts 12 are used to limit the relative position of the stud 7 and the pipe joint 3. The relative position of the protective plate 1 and the connecting pipe 8 can be adjusted as needed. A convex ring 11 is provided on the side of the through hole facing the first nut 12, which is concentrically arranged with the through hole. The convex ring 11 is connected and fixed to the pipe joint 3. The design of the convex ring 11 facilitates increasing the contact range between the first nut 12 and the connecting pipe 8.

[0024] See Figures 1-3 Both ends of the stud 7 are equipped with lugs 10. One end of the lug 10 is connected and fixed to a horizontal stiffener 6. The horizontal stiffener 6 is connected and fixed to the guard plate 1. Between the two horizontal stiffeners 6, there are multiple vertical stiffeners 2 that are welded and fixed to the guard plate 1. On the opposite sides of the two horizontal stiffeners 6, there are multiple short stiffeners 4 that are welded and fixed to the guard plate 1. The short stiffeners 4, vertical stiffeners 2 and horizontal stiffeners 6 together improve the deformation resistance of the guard plate 1.

[0025] See Figures 1-3 A circular hole 15 is provided on the upper surface of the lug 10. The end of the stud 7 passes through the circular hole 15. A second nut 13 is provided on one side of the circular hole 15 and is threadedly connected to the stud 7. A support plate 5 is provided between the second nut 13 and the lug 10 to limit the position of the second nut 13. The end of the stud 7 passes through the support plate 5. Two support plates 5 on a guard plate 1 are arranged between two second nuts 13. Three support rods 9 are installed on the side of the support plate 5 facing the horizontal rib plate 6. The side of the horizontal rib plate 6 facing the support plate 5 and the side of the lug 10 facing the support plate 5 are both machined with positioning holes 14 that mate with the corresponding support rods 9. The end of the support rod 9 away from the support plate 5 is inserted into Inside the positioning hole 14, the end of the stud 7 passes through the round hole 15 and the second nut 13 is screwed on. The two second nuts 13 cooperate with the two horizontal stiffeners 6 to complete the assembly of the stud 7 and the guard plate 1, which facilitates the assembly and disassembly of the stud 7 and the guard plate 1. The end of the stud 7 passes through the support plate 5 and the second nut 13 is screwed on. Then, under the support of the support plate 5 and the support rod 9, there is a gap between the second nut 13 and the horizontal stiffener 6. Therefore, when the second nut 13 and the stud 7 cannot be separated normally, the stud 7 can be cut off by using the gap between the support plate 5 and the horizontal stiffener 6. Then, the cut-off stud 7 can be separated from the other stud 7 and the other stud 7 can be reused.

[0026] See Figure 1 and Figure 4 One end of the stud 7 has a threaded blind hole 17, and the end of the stud 7 away from the threaded blind hole 17 is connected and fixed with a threaded head 16, so that the threaded head 16 on one stud 7 is screwed into the threaded blind hole 17 on another stud 7, and so on, to realize the assembly of multiple studs 7. When a stud 7 is damaged, the damaged stud 7 can be replaced individually, which helps to reduce the cost of replacing parts.
