[0002] The foundation pit support structure is a structural measure taken during the excavation process to prevent earthwork collapse. It supports, reinforces and protects the side walls of the deep foundation pit and the surrounding environment.

[0003] After searching, the applicant found that a Chinese patent disclosed "a support structure for foundation pits", and its publication (announcement) number is "CN213204151U". This patent mainly realizes the installation and disassembly of the entire support structure by cooperating the reinforcing rod with the U-shaped block and the positioning tube and connecting the first fixed seat, and the first diagonal rod and the second diagonal rod with the second connecting seat, the second fixed seat and the third fixed seat. The installation speed is fast and the construction efficiency is high. At the same time, it is easy to disassemble quickly, so that it is convenient for reuse. However, in the original document description of the application, the overall support effect of the device is not good when supporting the foundation pit, and it is easy to fall off during work. For this reason, we propose a support structure for foundation pits. Utility Model Content

Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0022] Example 1, please refer to the attached Figure 1 -Attached Figure 5 The utility model provides a technical solution: a supporting structure for a foundation pit, including a supporting structure body 1, a moving component 2 and a limiting component 3 are installed inside and on the top of the supporting structure body 1, a fixing component 4 is installed on the side of the moving component 2, the fixing component 4 includes a connecting rod 41, a telescopic cylinder 42 and a fixing rod 43, the output end of the telescopic cylinder 42 is fixedly installed with a clamping block 421, the side of the connecting rod 41 close to the clamping block 421 is fixedly connected to the side of the telescopic cylinder 42, one end of the fixing rod 43 is clamped to the outer surface of the clamping block 421, and the outer surfaces of the fixing rod 43 and the connecting rod 41 are both provided with a circular hole A.

[0023] In this embodiment, the setting of the A fixing plate 11 and the B fixing plate 12 prevents the side walls of the foundation pit and the surrounding environment from being supported, and the setting of the cone nails 111 facilitates the better fixing of the A fixing plate 11 and the B fixing plate 12 on the outer surface of the foundation pit.

[0024] The supporting structure body 1 includes an A fixing plate 11 and a B fixing plate 12, which are hingedly connected to each other. Multiple sets of cone nails 111 are fixedly installed on the side of the A fixing plate 11, and multiple sets of threaded holes are opened on the top of the A fixing plate 11.

[0025] In this embodiment, the setting of the movable plate 21 can increase the contact area between the A fixed plate 11 and the foundation pit, making the device more stable. The setting of the movable block 22 can fix the movable plate 21 after movement.

[0026] The moving assembly 2 includes a moving plate 21, a moving block 22 and a limit block 23. The bottom of the moving block 22 is fixedly connected to the top of the moving plate 21. A circular hole B is opened on the top of the moving block 22. A fixing bolt 221 is installed inside the circular hole B, and the fixing bolt 221 is threadedly connected to the inside of the threaded hole.

[0027] The side of the movable plate 21 close to the connecting rod 41 is fixedly connected to the side surface of the limiting block 23 , and the bottom of the connecting rod 41 is in contact with the outer surface of the limiting block 23 .

[0028] Specifically, the connecting rod 41 and the fixing rod 43 are swung so that the two are at the same horizontal height, and then the telescopic cylinder 42 is started, and the output end of the telescopic cylinder 42 is used to push the block 421 into the interior of the fixing rod 43, driving the fixing rod 43 to move toward the position of the B fixing plate 12. Due to the principle of mutual force, the A fixing plate 11 and the B fixing plate 12 are pushed against each other, thereby effectively preventing the loosening of the cone nail 111 and causing the entire device to fall.

[0029] Example 2, please refer to the attached Figure 1 -Attached Figure 5 The utility model provides a technical solution: a supporting structure for a foundation pit, including a supporting structure body 1, a moving component 2 and a limiting component 3 are installed inside and on the top of the supporting structure body 1, a fixing component 4 is installed on the side of the moving component 2, the fixing component 4 includes a connecting rod 41, a telescopic cylinder 42 and a fixing rod 43, the output end of the telescopic cylinder 42 is fixedly installed with a clamping block 421, the side of the connecting rod 41 close to the clamping block 421 is fixedly connected to the side of the telescopic cylinder 42, one end of the fixing rod 43 is clamped to the outer surface of the clamping block 421, and the outer surfaces of the fixing rod 43 and the connecting rod 41 are both provided with a circular hole A.

[0030] In this embodiment, the fixed block 211 is provided to provide a rotation effect for the A rotating rod 212 and to adjust the positions of the connecting rod 41 and the telescopic cylinder 42.

[0031] A fixed block 211 is fixedly installed on the side of the movable plate 21 , and an A rotating rod 212 is installed on the inner wall of the fixed block 211 , and the two are rotationally connected. The outer surface of the A rotating rod 212 is fixedly connected to the inside of the connecting rod 41 .

[0032] In this embodiment, by setting the flip plate 31, the position of the moving block 22 and the moving plate 21 can be restricted to prevent the moving plate 21 from falling out from the inside of the A fixed plate 11. By setting the B rotating rod 321, the flipping effect of the flip plate 31 can be achieved.

[0033] The limiting assembly 3 includes a flip plate 31 and a template 32. The flip plate 31 is clamped to the inner wall of the template 32. A B rotating rod 321 is installed on the side of the template 32. One end of the B rotating rod 321 passes through the interior of the flip plate 31, and the two are fixedly connected.

[0034] The bottom of the template 32 is fixedly connected to the edge of the top of the A fixed plate 11 , and the flip plate 31 is fixed to the edge of the top of the A fixed plate 11 through a threaded bolt 311 .

[0035] Specifically, flip the flip plate 31 so that the bottom of the flip plate 31 contacts the top of the A fixed plate 11, and then use the threaded bolt 311 to fix the position of the flip plate 31, so that the moving distance of the movable plate 21 can be limited to prevent the movable plate 21 from falling off. On the contrary, loosen the threaded bolt 311 and open the flip plate 31, so that the movable plate 21 can be taken out from the inside of the A fixed plate 11, thereby facilitating the staff to quickly replace and repair the movable plate 21.

[0036] Working principle:

[0037] Step 1: First, the staff aligns the A device with the angle of the foundation pit, then swings the A fixing plate 11 and the B fixing plate 12 toward the edge of the foundation pit, so that the cone nails 111 enter the interior of the foundation pit and fix the positions of the A fixing plate 11 and the B fixing plate 12. Then, the movable plate 21 is pulled out from the interior of the A fixing plate 11. When it reaches the appropriate length, the position of the movable plate 21 is fixed with the fixing bolts 221.

[0038] The second step, finally, uses the A rotating rod 212 to adjust the position of the telescopic cylinder 42 and the fixed rod 43, so that the axis of the fixed rod 43 and the telescopic cylinder 42 are at the same horizontal height, and starts the telescopic cylinder 42, uses the output end of the telescopic cylinder 42 to drive the block 421 into the interior of the fixed rod 43, and drives the fixed rod 43 to push the B fixed plate 12. Through the mutual principle of force, the A fixed plate 11 and the B fixed plate 12 are always in a mutual pushing effect. At this point, the entire workflow ends.
