Description

Technical Field

[0001] This utility model relates to the field of green building construction technology, specifically an environmentally friendly support structure for foundation pits. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage work should be done. For shallow excavations, slope protection can be used to stabilize the soil slope. The slope should be determined according to relevant construction regulations. Excavation pit support refers to the measures taken to support, reinforce and protect the sidewalls and surrounding environment of deep excavations to ensure the safety of underground structure construction and the surrounding environment.

[0003] An existing deep foundation pit support structure (application number: CN202110096446.9) uses a device where, when the angle between the inner wall and the bottom wall of the foundation pit is obtuse, the support base is first fixed to the bottom wall of the foundation pit using fasteners. Then, the hydraulic cylinder is activated, and the output shaft of the hydraulic cylinder pushes the sliding block to slide in the adjustment groove. The support rod pushes the support plate to press tightly against the inner wall of the foundation pit, thus completing the support. This method is time-saving and labor-saving. At the same time, when the fixing column is inserted into the bottom wall of the foundation pit through the fixing hole, the limiting block passes through the first limiting groove on the fixing plate and the second limiting groove on the limiting block in sequence until the limiting plate is in close contact with the lower end face of the limiting block. Then, the limiting plate is rotated 90 degrees, thereby preventing the fixing plate from detaching from the fixing groove, thus increasing the connection strength between the fixing column and the bottom wall of the foundation pit. However, the existing foundation pit support structure still has the following problems during use:

[0004] The aforementioned foundation pit support structure uses a hydraulic cylinder as the power mechanism. The output shaft of the hydraulic cylinder pushes the sliding block to slide in the adjustment groove. Since the support of deep foundations is for long-term protection, the use of hydraulic cylinders will increase the cost of use. At the same time, the support plate cannot be adjusted and needs to be customized according to the site environment of the slope. The support plate will be limited in use in other projects. Moreover, there is no protection between the surface of the construction site and the landslide, which is prone to landslide accidents. Therefore, it is necessary to develop an environmentally friendly foundation pit support structure for use in the existing green building construction technology field. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, such as poor protection effect, high cost, and limited application in other projects, this utility model proposes an environmentally friendly foundation pit support structure.

[0010] Preferably, an operating plate is fixedly mounted on the deflection block, and an adjusting rod is movably mounted on the operating plate, with the other end of the adjusting rod corresponding to the mounting plate.

[0011] Preferably, the mounting block is fixedly equipped with two sets of bearing blocks, each set having two bearing blocks.

[0015] 1. This utility model utilizes the slope of the foundation pit. By rotating and adjusting the bolts on the assembly block, a rotating disc on the rotating rod rotates in the rotating cavity. The traction block moves on two connecting rods. Under the action of the adjusting rod, the deflection block rotates on the assembly rod via the rotating block.

The distance between sections is fixed, and fastening bolts are installed in the mounting holes on the mounting block and the mounting holes on the fixing block. At this time, the mounting block is fixed to the construction site, and the fixing block is fixed to the bottom of the foundation pit. The sliding block moves on the guide rod, and the extension block drives the vertical rod to move until the threaded rod moves into the insertion hole of the operating block. The first limit nut and the second limit nut are rotated on the threaded rod respectively, so that the first limit nut and the second limit nut clamp the operating block. Through all-round protection, landslides are avoided, and its use in other projects is not limited.

[0016] 2. Traditional foundation pit support technologies use a large amount of reinforced concrete, which not only increases construction difficulty but also generates a large amount of construction waste and carbon emissions. In contrast, the new support technology uses integrated adjustable steel components instead of traditional reinforced concrete supports, significantly reducing the amount of reinforced concrete used, thereby reducing carbon emissions. It is also recyclable, reducing resource waste and further improving environmental friendliness. Attached Figure Description

Both the mounting block 21 and the fixed block 13 have multiple mounting holes 51. Fastening bolts 22 are threaded into the mounting holes 51 and the construction site 10, respectively.

The first limiting nut 72 is located above the second limiting nut 73, and the first and second limiting nuts 72 are located on either side of the operating block 92. Rotating the adjusting bolt 95 on the assembly block 80 causes the rotating disk 97 on the rotating rod 96 to rotate in the rotating cavity 94. The traction block 91 moves on the two connecting rods 90. Under the action of the adjusting rod 83, the deflection block 20 rotates on the assembly rod 33 via the rotating block 40, facilitating adjustment of the deflection block 20 according to the slope of the foundation pit. The mounting block 21 is attached to the surface of the pit sidewall 12, and the fixing block 13 is attached to the bottom surface 11 of the pit.

At this time, the fixing block 13 fits against the bottom surface 11 of the foundation pit, and the mounting block 21 fits against the construction site 10. Then, the positioning bolt 31 is used to install the threaded hole 30 on the connecting block 23 with the slider 99. The adjustment between the deflection block 20 and the movable block 41 is then completed. The distance is fixed, and fastening bolts 22 are installed in the mounting holes 51 on the mounting block 21 and the mounting holes 51 on the fixing block 13. At this time, the mounting block 21 is fixed to the construction site 10, and the fixing block 13 is fixed to the bottom surface 11 of the foundation pit.
