Description

Technical Field

[0001] This utility model belongs to the field of foundation pit support technology, specifically relating to a combined inclined support for foundation pit support. Background Technology

[0002] During engineering construction, foundation pits are excavated. To ensure the stability of the foundation walls and guarantee construction safety, support measures are required for the foundation pits. Current foundation pit support systems include horizontal or diagonal supports. However, existing support structures are inconvenient to install and dismantle, cannot be reused, resulting in high construction costs. Furthermore, the support structures are relatively simple, with limited load-bearing capacity, leading to some degree of displacement of the support structure, deformation of the foundation pit, and insufficient support strength to meet construction requirements. Therefore, overcoming these technical problems and defects is a key issue that needs to be addressed. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a combined inclined support for foundation pit support.

[0004] The purpose of this utility model is achieved as follows: A combined inclined support for foundation pit support includes a water-stop steel plate and a support steel plate. Inclined rods are uniformly fixed to the left side of the water-stop steel plate, and each inclined rod has a pointed end. The right side of the water-stop steel plate abuts against the support steel plate. A pressure plate is fixed to the upper surfaces of the water-stop steel plate and the support steel plate. A supporting steel plate abuts against the lower part of the right side of the support steel plate. A first inclined support mechanism is detachably connected between the upper part of the right side of the support steel plate and the upper right side of the support steel plate. A second inclined support mechanism is detachably connected between the middle part of the right side of the support steel plate and the middle part of the upper surface of the support steel plate. A first anchor rod is vertically anchored between the first inclined support mechanism and the support steel plate, and a second anchor rod is vertically anchored between the first inclined support mechanism, the second inclined support mechanism, and the support steel plate.

[0005] Furthermore, the first inclined support mechanism includes a first inclined support rod, the two ends of which abut against the right side of the support steel plate and the upper surface of the support steel plate, respectively. A first support rod is detachably connected to the upper part of the left side of the first inclined support rod, and the other end of the first support rod is fixed to the middle of the right side of the support steel plate. The first support rod and the first inclined support rod are distributed perpendicularly. The first inclined support rod provides oblique support to the upper part of the support steel plate, and the first support rod supports the first inclined support rod, thereby improving the support effect of the first inclined support rod on the support steel plate and thus improving the support effect of the support steel plate on the foundation pit.

[0006] Furthermore, a first wedge block is fixedly connected to the free end of the first support rod, and a first wedge groove matching the first wedge block is provided on the upper left side of the first inclined support rod, which facilitates the installation and disassembly of the first inclined support rod, allowing the first inclined support rod to be reused, thereby reducing construction costs.

[0007] Furthermore, the second inclined support mechanism includes a second inclined support rod, the two ends of which abut against the right side of the support steel plate and the upper surface of the support steel plate, respectively. A second support rod is detachably connected to the lower part of the left side of the second inclined support rod, and the other end of the second support rod is fixed to the lower part of the right side of the support steel plate. The second support rod and the second inclined support rod are distributed perpendicularly. The second inclined support rod provides oblique support to the middle part of the support steel plate, and the second support rod supports the second inclined support rod, thereby improving the support effect of the second inclined support rod on the support steel plate, and thus improving the support effect of the support steel plate on the foundation pit.

[0008] Furthermore, a second wedge block is fixedly connected to the free end of the second support rod, and a second wedge groove matching the second wedge block is provided on the lower left side of the second inclined support rod, which facilitates the installation and disassembly of the second inclined support rod, allowing the second inclined support rod to be reused, thereby reducing construction costs.

[0009] Furthermore, the first anchor rod is vertically anchored between the first inclined support rod and the support steel plate. The first anchor rod fixes the first inclined support rod and the support steel plate, preventing the first inclined support rod from shifting and improving the support strength of the first inclined support rod for the support steel plate.

[0010] Furthermore, the second anchor rod is vertically anchored between the first inclined support rod, the second inclined support rod, and the support steel plate. The second anchor rod further fixes the first inclined support rod, the second inclined support rod, and the support steel plate, preventing displacement of the first and second inclined support rods and improving the support strength of the first and second inclined support rods for the support steel plate.

[0011] Furthermore, anchoring holes are provided in the first inclined support rod, the second inclined support rod, and the support steel plate.

[0012] Furthermore, the lower ends of the first and second anchor rods are both triangular pyramidal structures. The first and second anchor rods extend into the bottom of the foundation pit. The triangular pyramidal structure can provide an anchoring effect, thereby improving the support strength of the first and second inclined support rods.

[0013] Furthermore, the insert tip is a triangular pyramid structure, which is inserted into the side wall of the foundation pit to fix the water-stop steel plate. The triangular structure of the insert tip can improve the fixing effect of the water-stop steel plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model relates to a combined oblique support for foundation pit support. It utilizes a water-stop steel plate to protect the sidewalls of the foundation pit from water. Oblique rods are evenly fixed to the left side of the water-stop steel plate, improving its fixation. Support steel plates are used to support the sidewalls of the foundation pit. Pressure plates connect the water-stop steel plate and the support steel plate. A first oblique support rod provides oblique support to the upper part of the support steel plate, a second oblique support rod provides oblique support to the middle part of the support steel plate, and a support steel plate provides lateral support to the bottom of the support steel plate. This effectively increases the supporting force on the support steel plate, thereby enhancing its support strength and preventing deformation of the foundation pit.

[0016] 2. The combined inclined support for foundation pit support of this utility model supports the first inclined support rod through the first support rod, supports the second inclined support rod through the second support rod, fixes the first inclined support rod and the support steel plate through the first anchor rod, and further fixes the first inclined support rod, the second inclined support rod and the support steel plate through the second anchor rod. This can effectively prevent the displacement of the first and second inclined support rods, improve the inclined support strength of the first and second inclined support rods, and thus improve the stability of the support steel plate.

[0017] 3. The combined inclined support for foundation pit support of this utility model installs the first inclined support rod through the first wedge groove and the first wedge block, and installs the second inclined support rod through the second wedge groove and the second wedge block. This facilitates the installation and disassembly of the first and second inclined support rods, allowing the first and second inclined support rods to be reused, thereby reducing construction costs.
