[0002] Construction projects refer to engineering entities formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. "Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, living, learning, and public activities. In some construction projects, foundation pits need to be opened in advance. In order to ensure the safety of personnel and prevent foundation pit collapse, support devices need to be arranged after the foundation pit is completed to prevent the foundation pit from collapsing.

[0003] Steel supports are set up to support the surrounding soil to prevent soil instability and collapse. Steel supports are usually composed of steel sheet piles, steel beams and steel pipes, and have the characteristics of high strength and rigidity.

[0004] At present, there is still a lack of a foundation pit anti-collapse support device that uses a connection assembly to connect the H plates on both sides, replacing the traditional welding method, and facilitating installation and disassembly. When a collapse occurs, the connecting pipe and related components in the main pipe are squeezed and collided to offset the force of the collapsed soil, making the support effect more effective.

[0005] Therefore, in view of the above problems, a foundation pit anti-collapse support device is proposed to solve the above problems. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention develops a foundation pit anti-collapse support device. The invention uses a connection assembly to connect the H plates on both sides, replacing the traditional welding method, which is convenient for installation and disassembly. When a collapse occurs, the connecting pipe and the related components in the main pipe are squeezed and collided to offset the force of the collapsed soil, making the support effect more effective.

[0007] The technical solution to the technical problem of the present invention is as follows: the present invention provides a foundation pit anti-collapse support device, comprising: an edge protection assembly and several groups of connection assemblies; the edge protection assembly comprises two H plates, one side of each H plate is respectively provided with a group of positive U plates and negative U plates, each positive U plate and each negative U plate are respectively connected to the corresponding H plate, the adjacent positive U plates and negative U plates are respectively staggered and connected, and each H plate is respectively connected to a group of connection columns; the connection assembly comprises a main pipe and a symmetrical connection pipe, the main pipe is connected to a square table, the square table bearing is connected to a T axis, the T axis passes through the main pipe, the T axis is rotated to connect to a symmetrical L axis, the symmetrical L axis is respectively rotated to connect to a mounting seat, and the symmetrical mounting seats are respectively connected to the corresponding connection pipes; the symmetrical connection pipes are respectively matched with the corresponding connection columns, and the symmetrical connection pipes are respectively connected to the contact circular plates. By adopting the connection assembly, the edge protection assemblies on both sides are formed into a whole. The connection pipe can move along the main pipe, which is convenient for realizing the connection of the connection pipe and the connection column into one, changing the previous welding method, improving work efficiency, and convenient for dismantling after the project is completed, which is convenient for use.

By adopting the connecting rod rotation connection method, the longitudinal hole plate and the longitudinal pin plate are moved closer to the support plate while the two are moved closer to each other, so that the longitudinal pin shaft is inserted into the longitudinal hole on the longitudinal hole plate. When soil collapse occurs, the longitudinal hole plate shears the longitudinal pin shaft, and the longitudinal hole plate and the longitudinal pin plate squeeze the support plate, thereby changing the previous way in which the main pipe is subjected to squeezing.

When the block swings into place, the brake block moves out of the L baffle area. Under the action of gravity, the brake block moves downward and close to the block. When collapse occurs, due to the contact of the block, the connecting pipe has a tendency to move inward, and the block is blocked by the brake block and cannot rotate, that is, the connecting pipe is prevented from moving inward, so that the block and the brake block are destroyed first.

[0012] As an optimization, the guide vertical pipe corresponds to the installation vertical rod threaded connection top screw. The main pipe is pre-drilled to facilitate the staff to pull the brake block upward to make it higher than the stop block when removing the connection assembly, and tighten the top screw to prevent the stop block from being blocked by the brake block when swinging.

The above technical solution has the following advantages or beneficial effects: 1. This device uses a connecting component to realize that the edge protection components on both sides form a whole, which changes the previous welding connection method and improves work efficiency. The connecting pipe can move along the main pipe, which is convenient for connecting the connecting pipe and the connecting column to become one, and is easy to install; the horizontal plug rod is inserted into the jack to facilitate the close connection of the connecting pipe and the connecting column.

[0016] 2. This device uses a brake block. In the initial state, the brake block contacts the L baffle plate and moves along the L baffle plate first. When the block swings into place, the brake block moves out of the L baffle plate area. Under the action of gravity, the brake block moves downward and close to the block block. When the longitudinal hole plate and the longitudinal pin plate approach the support plate, the two approach each other, so that the longitudinal pin shaft is inserted into the longitudinal hole on the longitudinal hole plate. The longitudinal hole plate and the longitudinal pin plate contact the support plate.

The brake block 324 drives the installation vertical rod 323 to move along the guide vertical tube 321. The installation vertical rod 323 drives the stop block 320 to move downward and contact the guide vertical tube 321.

[0042] The workflow of this embodiment is: When the regular polygonal plate 24 is rotated, the contact circular plate 26 drives the horizontal insertion rod 27 to be inserted into the insertion hole 15 until the contact circular plate 26 contacts the connecting column 14 and the horizontal insertion rod 27 is completely inserted into the insertion hole 15 .

[0043] The device adopts a connecting component 2 to realize that the edge protection components 1 on both sides are formed into a whole, which changes the previous welding connection method and improves work efficiency. The connecting pipe 21 can move along the main pipe 22, which is convenient for connecting the connecting pipe 21 and the connecting column 14 to become one, and the installation is convenient; the horizontal insertion rod 27 is inserted into the socket 15, which is convenient for the connecting pipe 21 to be tightly connected with the connecting column 14.

[0044] The device adopts a brake block 324. In the initial state, the brake block 324 contacts the L baffle plate 316, and the brake block 324 first moves along the L baffle plate 316. When the block 317 swings into place, the brake block 324 moves out of the L baffle plate 316 area. Under the action of gravity, the brake block 324 moves downward and close to the block 317; while the longitudinal hole plate 310 and the longitudinal pin plate 37 approach the support plate 215, the two approach each other, so that the longitudinal pin shaft 38 is inserted into the longitudinal hole on the longitudinal hole plate 310, and the longitudinal hole plate 310 and the longitudinal pin plate 37 contact the support plate 215. When collapse occurs, since the block 317 contacts the brake block 324, the connecting pipe 21 has a tendency to move inward, and the block 317 is blocked by the brake block 324 and cannot rotate, that is, the connecting pipe 21 is prevented from moving inward, so that the block 317 and the brake block 324 are destroyed first. The longitudinal hole plate 310 shears the longitudinal pin shaft 38, and the longitudinal hole plate 310 and the longitudinal pin plate 37 squeeze the support plate 215, thereby changing the conventional way in which the main pipe 22 is subjected to squeezing.
