[0002] Foundation pit support is a measure of support, reinforcement and protection adopted for the side walls and surrounding environment to ensure the safety of underground structure construction and the surrounding environment of the foundation pit. Generally, support piles and mudguards are set up to enclose and form a safe working space.

[0003] In the existing technology, in order to ensure the support capacity and construction cost of the supporting piles, a certain distance is left between two adjacent supporting piles. For areas where the soil contains more water, the soil is less stable and is very likely to slide through the distance between the two supporting piles, causing certain risks. Therefore, a connecting rod and a mudguard are installed between two adjacent supporting piles. The mudguard fits the soil layer of the foundation pit, the two ends of the connecting rod are connected to the two adjacent supporting piles, and the middle part is connected to the mudguard. However, in actual use, the soil squeezes the mudguard, causing the middle part of the connecting rod to be easily squeezed and deformed, thereby causing the soil around the foundation pit to leak into the foundation pit at the joint of the mudguard, affecting the support effect. Therefore, it is urgent to solve this problem.

[0022] Example

[0023] See also Figure 1-3 As shown:

[0024] The utility model provides a foundation pit supporting and stabilizing device, comprising a fender A, a connecting rod B, an L-shaped supporting rod and a reinforcement component.

[0025] In actual implementation, grooves for securing connecting rod B are pre-reserved on the support piles, allowing the ends of connecting rod B to connect to two adjacent support piles in the foundation pit. Mudguard A is then positioned between the two adjacent support piles in the foundation pit and connected to one side of connecting rod B, forming a protective structure for the soil surrounding the foundation pit. An L-shaped support rod is installed on the other side of connecting rod B, with its bottom fixed in the foundation pit. A reinforcement assembly is placed on the L-shaped support rod and connected to connecting rod B. Together, the reinforcement assembly and the L-shaped support rod form a triangular support structure.

[0026] By setting a triangular support on one side of the fender A and the connecting rod B, the protection ability of the fender A and the connecting rod B to the foundation pit soil on the other side is increased, avoiding the deformation of the fender A and the connecting rod B caused by soil squeezing.

[0027] The L-shaped support rod is mainly composed of a vertical rod 11 and a horizontal rod 12. The vertical rod 11 is vertically placed on one side of the connecting rod B, and the horizontal rod 12 is horizontally placed on the ground of the foundation pit, and the bottom end of the vertical rod 11 is fixedly connected to one end of the horizontal rod 12.

[0028] The reinforcement assembly includes a clamping portion and a fixing portion; the clamping portion is slidably connected to the vertical rod 11 and is clamped to the connecting rod B; the fixing portion is used to fix the horizontal rod 12 and abuts against the clamping portion.

[0029] The clamping portion mainly consists of a fastening bolt 20 , a first slider 21 , an abutment plate 22 , a diagonal support rod 13 , a second fastening bolt 30 , a second slider 31 and a second abutment plate 32 .

[0030] A vertical slide groove 111 is provided on one side of the vertical rod 11 along the vertical direction; a long hole 112 is provided in the vertical slide groove 111 .

[0031] Both sides of the first slider 21 are clamped with the vertical slide groove 111, and the first slider 21 can slide in the vertical direction of the vertical slide groove 111; the abutment plate 22 is arranged on the other side of the vertical rod 11; the fastening bolt 20 passes through the through hole on the first slider 21 and forms a threaded connection with the abutment plate 22, and the end of the fastening bolt 20 passes through the abutment plate 22 and forms an abutment with the lower end surface of the middle part of the connecting rod B; one end of the diagonal support rod 13 is hinged to the first slider 21, and the other end abuts against the fixed part.

[0032] The second slider 31 forms a sliding connection with the vertical slide groove 111; the second abutment plate 32 is arranged on the other side of the vertical rod 11; the second fastening bolt 30 passes through the through hole on the second slider 31 and forms a threaded connection with the second abutment plate 32, and the end of the second fastening bolt 30 passes through the second abutment plate 32 and forms an abutment with the lower end surface of the middle part of the other connecting rod B.

[0033] This arrangement allows both connecting rods B to abut against the clamping portion, eliminating the need to drill holes in the connecting rods B. Support can be provided to one side of the connecting rods B, and when the other side of the connecting rods B is subjected to squeezing force, the force can be transmitted to the vertical rod 11. This provides stable support while reducing the difficulty of installation during actual construction and improving the efficiency of foundation pit support.

[0034] The fixing portion is mainly composed of a first fixing pin 41, a second adjusting pin 42 and a second fixing pin 43. The horizontal rod 12 is provided with a fixing groove 121 along the length direction. The fixing groove 121 is provided with a first fixing hole 122 and a position adjustment elongated hole 123 at one end close to the vertical rod 11. One end of the first fixing pin 41 is fixed to the ground in the foundation pit after passing through the first fixing hole 122. The second adjusting pin 42 is fixed to the ground in the foundation pit after passing through the position adjustment elongated hole 123. By providing the second adjusting pin 42, it can cooperate with the clamping portion to form abutment against the connecting rod B, which can adapt to the connecting rod B in different positions, thereby improving the flexibility of use.

[0035] The second fixing hole 124 is arranged in the fixing groove 121; the diagonal support rod 13 forms abutment with the second adjusting pin 42, which enables the lateral extrusion force exerted on the vertical rod 11 to be transmitted to the horizontal rod 12 and the second adjusting pin 42, thereby improving the supporting ability of the vertical rod 11 to the connecting rod B.

[0036] A second fixing hole 124 is provided at one end of the horizontal rod 12 away from the vertical rod 11; the second fixing pin 43 passes through the second fixing hole 124 and is fixed to the ground in the foundation pit, increasing the friction between the horizontal rod 12 and the ground, and further improving the supporting capacity of the vertical rod 11 for the connecting rod B.

[0037] It also includes an anti-sliding block; there are at least three anti-sliding blocks, and all of them are slidably connected to the fixing groove 121, and the anti-sliding block is provided with a through hole through which the first fixing pin 41, the second adjusting pin 42 and the second fixing pin 43 pass. The anti-sliding block can be set as a wooden block to increase friction and enhance the fixing effect of the first fixing pin 41, the second adjusting pin 42 and the second fixing pin 43 on the horizontal rod 12.
