[0039] The embodiment of this application discloses a green, environmentally friendly and fast deep foundation pit bracing removal and noise reduction structure. Referring to Figure 1 and Figure 2 , the green, environmentally friendly and fast deep foundation pit bracing removal and noise reduction structure includes a first support frame 1 and a second support frame 2.

[0040] As Figure 2 and Figure 3 shown, the first support frame 1 is arranged in the deep foundation pit and abuts against the side wall of the deep foundation pit. A protective net 13 is arranged on one side of the first support frame 1 close to the wall of the deep foundation pit. The protective net 13 is detachably connected to the first support frame 1 by means of hooks, etc.; when the side wall of the deep foundation pit is a vertical side wall, the first support frame 1 can limit the position of the side wall of the deep foundation pit, reduce the risk of collapse of the side wall of the deep foundation pit, and prevent people, objects from falling or flying gravel from hurting people through the protective net 13, avoiding accidental injuries during the construction process and ensuring the safety of construction workers; when the side wall of the deep foundation pit is set with a slope, the first support frame 1 can prevent people, objects from falling or flying gravel from hurting people through the protective net 13, avoiding accidental injuries during the construction process and ensuring the safety of construction workers.

[0041] The first support frame 1 includes vertical poles 11 and horizontal bars 12. A number of vertical poles 11 are vertically arranged in the deep foundation pit. A number of horizontal bars 12 are detachably connected to the number of vertical poles 11. The number of horizontal bars 12 and the number of vertical poles 11 are connected to form a contact part that abuts against the wall of the deep foundation pit and an extension part that extends into the deep foundation pit. The vertical poles 11 provide the main vertical support for the first support frame 1, directly bear the pressure of the side wall of the deep foundation pit and transmit it to the bottom of the deep foundation pit. The horizontal bars 12 are connected to the vertical poles 11 to form the overall structure of the support frame, disperse and resist the pressure of the side wall of the deep foundation pit, and improve the lateral stability and overall stiffness of the support frame; the connection between the vertical poles 11 and the horizontal bars 12 adopts a detachable design, making the removal of the support frame fast and convenient, reducing the noise and dust during the removal process, and helping to protect the environment around the construction site; in addition, the detachable connection also allows the support frame to be reused in deep foundation pits of different sizes, improving the utilization rate and economy of materials.

[0042] In the embodiment of this application, diagonal braces 14 are also provided. The horizontal bars 12, vertical poles 11 and diagonal braces 14 are all metal pipes. The horizontal bars 12 and vertical poles 11 are detachably connected by fasteners. A number of diagonal braces 14 are respectively detachably connected to the corresponding vertical poles 11 and / or horizontal bars 12 by fasteners; the diagonal braces 14 improve the structural stability of the first support frame 1, thereby reducing the construction risk and improving the safety of the construction site.

[0043] There are four first support frames 1, and the four first support frames 1 are respectively abutted against the wall parts on the four sides of the deep foundation pit. Each first support frame 1 is detachably connected to the adjacent two first support frames 1 by fasteners. The first support frames 1 are respectively arranged on the four side walls of the deep foundation pit, which can provide comprehensive lateral support for the deep foundation pit, ensure the stability of the deep foundation pit during use, reduce the local stress concentration on the side walls of the deep foundation pit, and thus reduce the risk of collapse or deformation.

[0044] As Figure 4 and Figure 5 shown, the second support frame 2 includes support piles 21, a first connecting beam 22, a second connecting beam 23 and diagonal bracing rods 24. The support piles 21 are vertically arranged in the deep foundation pit.

[0045] In the embodiment of the present application, the support piles 21 are reinforced concrete piles. The support piles 21 are detachably connected to the first connecting beam 22, the second connecting beam 23 and the diagonal bracing rods 24. There are several support piles 21, and the several support piles 21 are equidistantly distributed in the deep foundation pit. There are several cross beams made of concrete pouring between the several support piles 21. The several support piles 21 are connected by the several cross beams to form a frame structure. The support piles 21 and the cross beams are connected to form a firm and stable frame structure, which improves the stability and safety of the deep foundation pit.

[0046] The first connecting beam 22 is a steel beam. There are several first connecting beams 22. One end of each first connecting beam 22 is detachably connected to the corresponding support pile 21. The end of each first connecting beam 22 away from the support pile 21 passes through the protective net 13 and is detachably connected to the side of the corresponding extension part away from the wall part of the deep foundation pit. The detachable connection between the first connecting beam 22 and the extension part can play a role in transmitting and dispersing the load, and the detachable connection design makes the removal of the first connecting beam 22 fast and simple.

The top of each second connecting beam 23 abuts against the bottom of the corresponding extension part; the second connecting beam 23 plays a role in transferring the earth pressure on the side wall of the deep foundation pit to the support pile 21, effectively bearing and dispersing the water and soil pressure on the side wall of the deep foundation pit, enhancing the overall stability of the deep foundation pit. The abutment of the top of the second connecting beam 23 and the bottom of the extension part enhances the overall stiffness and stability of the structure, enabling the entire support system to better bear the water and soil pressure on the side wall of the deep foundation pit.

[0048] As Figure 5 shown, there are several diagonal tension rods 24. One end of each diagonal tension rod 24 is detachably connected to the support pile 21, and the other end of each diagonal tension rod 24 away from the support pile 21 is detachably connected to the corresponding first connecting beam 22 or second connecting beam 23; the diagonal tension rods 24 enhance the structural stability of the second support frame 2, reduce the construction risk, and improve the safety of the construction site.

[0049] Specifically, the first support frame 1 can limit the position of the side wall of the deep foundation pit, reduce the risk of collapse of the side wall of the deep foundation pit, or protect construction workers and falling stones, ensuring the construction safety of construction workers; the second support frame 2 connects the side wall of the deep foundation pit and the first support frame 1, providing lateral support for the side wall of the deep foundation pit and the first support frame 1, improving the stability of the deep foundation pit and the first support frame 1; at the same time, the detachable connection setting can reduce the possible manual knocking and mechanical cutting operations when demolishing the deep foundation pit support structure, improve the problem of large noise during the demolition of the existing deep foundation pit support structure, and achieve the goal of green, environmental-friendly and rapid construction.

[0050] When it is necessary to disassemble the green, environmental-friendly, rapid deep foundation pit support and noise reduction structure, it is necessary to follow the principle of "first replace the support, then disassemble the support; first the connecting beam, then the load-bearing beam; first the small support, then the large support", and the following method can be used to disassemble the green, environmental-friendly, rapid deep foundation pit support and noise reduction structure: Separate the diagonal tension rods 24. After the diagonal tension rods 24 are separated, inject an expanding agent into the bolt holes on the first connecting beam 22 and the second connecting beam 23 to conduct static blasting on the first connecting beam 22 and the second connecting beam 23; after the static blasting of the first connecting beam 22 and the second connecting beam 23 is completed, remove the first connecting beam 22 and the second connecting beam 23, then drill holes in the support pile 21 and inject an expanding agent. After the support pile 21 is statically blasted, cut off the steel bars protruding from the bottom of the pit with a hydraulic shear, and remove the crushed slag in the foundation pit to complete the disassembly of the second support frame 2; finally, disassemble and transport the first support frame 1 to complete the disassembly of the green, environmental-friendly, rapid deep foundation pit support and noise reduction structure.

[0051] Through the above green and environmentally friendly and fast deep foundation pit bracing removal and noise reduction structure and the matching disassembly method, it is possible to reduce the noise during disassembly while ensuring the safety and effectiveness of the deep foundation pit support, and improve the problem of relatively large noise during the removal of the existing deep foundation pit support structure; moreover, each part of the green and environmentally friendly and fast deep foundation pit bracing removal and noise reduction structure can be detachably connected, enabling the recycling of materials and responding to the development of green, environmentally friendly and sustainable construction.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
