Description

Technical Field

[0001] The present application relates to the field of foundation pit retaining structures, and in particular to a retaining structure surrounding a foundation pit. Background Art

[0002] The foundation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. The soil around the excavated foundation pit is relatively soft, and people approaching it are prone to landslides. During the construction of the foundation pit, for safety reasons, people need to set up enclosures around the foundation pit to prevent people from accidentally falling into the foundation pit and causing safety accidents.

[0003] Guardrails must be installed around foundation pits with a depth of more than 2 meters, and the horizontal distance between the guardrails and the edge of the foundation pit should not be less than 0.5 meters. The foundation pit enclosure structure generally includes columns, crossbars and dense mesh. The columns and crossbars are the main supporting structures of the foundation pit guardrail net, which are made of steel pipes or square pipes. The columns are generally inserted into the top surface of the foundation pit to achieve the stability of the columns to provide support and stability for the guardrail. The dense mesh is installed between the columns to safely isolate the foundation pit area from the surrounding environment and ensure that pedestrians and vehicles cannot directly enter the foundation pit area. The purpose is to increase the safety of the guardrail to prevent people or objects from accidentally passing through the railings into the foundation pit.

[0004] Regarding the above-mentioned related technologies, when fixing the dense mesh to the column, workers generally use iron wire to pass through the dense mesh and the column to tie them up. The iron wire will pierce the dense mesh and thus destroy the structure of the dense mesh, causing the dense mesh structure to become loose, deformed or broken. When the protective structure encounters strong winds, the dense mesh is prone to tearing at the punctured position, resulting in a larger damaged area, reducing the strength of the dense mesh, and thus reducing the safety performance and stability of the enclosure structure. Utility Model Content

[0005] In order to ensure the stability of the enclosure structure while installing the close-mesh net without destroying the close-mesh net structure, the present application provides a surrounding enclosure structure for a foundation pit.

[0006] The present application provides a foundation pit surrounding structure adopting the following technical solution:

[0007] A surrounding protective structure for a foundation pit, comprising a plurality of columns, wherein the plurality of columns are sequentially arranged around the foundation pit, and one end of the columns are inserted into the top surface of the foundation pit; a first cross bar is provided between two adjacent columns, and the first cross bar is connected to the top of the column; a dense mesh is provided on one side of the column, and the dense mesh covers all the columns and the first cross bar, and one end of the dense mesh is close to the top surface of the foundation pit and is connected to the top surface of the foundation pit; the first cross bar is provided with a magnet, and the first cross bar and the dense mesh are fixed by the magnet; the column is provided with a plurality of fixing parts, and the fixing parts are C-shaped, and the fixing parts can be clamped on the surface of the column along the axis direction of the column to connect the dense mesh with the column.

[0008] By adopting the above technical solution, the column and the first crossbar support the dense mesh to form an enclosure structure, and the dense mesh is fixed to the first crossbar by a magnet, which not only ensures the firm connection of the dense mesh, but also facilitates the workers to carry out the unfolding and installation operations, thereby improving the construction efficiency. The dense mesh is fixed to the column by a fixing piece, which ensures the integrity of the dense mesh, reduces the possibility of the dense mesh being damaged, and improves the stability of the maintenance structure.

[0009] Optionally, both the upright post and the first crossbar are coated with red and white logos.

[0010] By adopting the above technical solution, the red and white paint colors are very visually impactful and attract people's attention. This eye-catching sign can remind pedestrians and vehicles of the danger ahead and reduce the occurrence of accidents.

[0011] Optionally, a dense mesh is arranged on a side of the column close to the foundation pit.

[0012] By adopting the above technical solution, the dense mesh is placed on the side of the column close to the foundation pit, which prevents the dense mesh from covering the markings on the column and the first crossbar. Since the grids of the dense mesh are denser, if the dense mesh is placed on the side of the column away from the foundation pit, the marking will be blocked, which will reduce the effect of the marking.

[0013] Optionally, a warning light is provided on a side of the first cross bar away from the top surface of the foundation pit.

[0014] By adopting the above technical solutions, the warning lights can emit bright light at night or in low light conditions, increasing the visibility of the foundation pit retaining structure. This is very important for pedestrians and vehicles to avoid mistakenly entering dangerous areas or accidents.

[0015] Optionally, a water retaining platform is provided on the top surface of the foundation pit, and the water retaining platform is located on a side of the column close to the foundation pit.

[0016] By adopting the above technical solution, the water retaining platform is located between the foundation pit and the columns. Its main function is to prevent rainwater from flowing into the foundation pit, effectively reduce the accumulation of water in the foundation pit, and provide a relatively stable construction environment.

[0017] Optionally, a drainage ditch is provided on the top surface of the foundation pit, and the drainage ditch is located on the side of the column away from the foundation pit.

[0018] By adopting the above technical solution, the drainage ditch is set on the side of the column away from the foundation pit, which can guide the surrounding rainwater and groundwater to a place away from the foundation pit, avoiding water flow into the foundation pit and affecting the construction progress and quality of the foundation pit.

[0019] Optionally, a warning line is provided on the top surface of the foundation pit, and the warning line is located on a side of the drainage ditch away from the column.

[0020] By adopting the above technical solution, the setting of the warning line can make the drainage ditch attract the attention of pedestrians, reminding them to leave the dangerous area and avoid accidents. When pedestrians pass by, they can recognize the existence of the warning line at a glance and stay alert.

[0021] Optionally, a plurality of protrusions are provided on the inner wall of the fixing member.

[0022] By adopting the above technical solution, the convex points on the inner wall of the fixing member can increase the friction between the fixing member and the column, so that the fixing member is more firmly connected to the column, which helps to prevent the fixing member from loosening or sliding and improves the firmness of the structure.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Use magnets to fix the dense mesh to the first crossbar, which not only ensures the firm connection of the dense mesh, but also facilitates the workers to carry out the unfolding and installation operations, thus improving the construction efficiency. Use the fixings to fix the dense mesh to the column, which ensures the integrity of the dense mesh, reduces the possibility of the dense mesh being damaged, and improves the stability of the maintenance structure;

[0025] 2. The upright column and the first crossbar are painted in red and white. With the setting of warning lights, they can attract the attention of pedestrians and vehicles from a distance, serve as a warning, and remind them to pay attention to safety;

[0026] 3. The water retaining platform and drainage ditch can prevent rainwater from flowing into the foundation pit as much as possible, reduce water accumulation in the foundation pit, and provide a relatively stable environment for construction; the warning line can remind pedestrians of the location of the drainage ditch and reduce the possibility of accidents.

[0033] The present application embodiment discloses a surrounding structure for a foundation pit. Figure 1 and Figure 2A surrounding structure for a foundation pit includes a plurality of vertically arranged columns 2, which are arranged in an array around the foundation pit 1 in sequence, and one end of each column 2 is inserted into the top surface of the foundation pit 1; a horizontal first crossbar 21 and a second crossbar 22 are arranged between each two adjacent columns 2, the first crossbar 21 is connected to the top of the column 2, and the second crossbar 22 is located below the first crossbar 21, and the first crossbar 21 and the second crossbar 22 are both bolted to the column 2, and the first crossbar 21 and the second crossbar 22 are used to support the column 2, thereby forming a stable supporting structure. The column 2 is covered with a dense mesh 3 on one side close to the foundation pit 1, and the dense mesh 3 is connected to all the columns 2 and the first crossbar 21, and the dense mesh 3 completely covers the space between the first crossbar 21 and the top surface of the foundation pit 1. The first crossbar 21 is provided with a plurality of magnets 32, and the magnets 32 are preferably neodymium iron boron magnets, and the magnets 32 fix the first crossbar 21 and the dense mesh 3 by adsorbing on the surface of the first crossbar 21.
