Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and relates to a foundation pit support structure which is convenient to install. Background Art

[0002] During the construction of underground buildings such as basements, it is necessary to excavate a foundation pit, and it is necessary to set up a support structure to protect the edge of the foundation pit, so as to avoid the problems of collapse or water leakage at the edge of the foundation pit during the construction of the basement.

[0003] In order to improve the strength of the support structure, the alternate arrangement of steel sheet piles and steel pipe piles is currently adopted. However, during the installation process, since the two are generally fixedly connected by welding or bolt connection, the angle and position between adjacent two steel sheet piles cannot be freely adjusted. On the one hand, it cannot meet the use of foundation pits with different shapes. On the other hand, the matching accuracy is relatively high, resulting in low installation efficiency. At the same time, when the cooperation between the two is not in place, it is also easy to affect the structural strength of the connection between the steel sheet pile and the steel pipe pile. In addition, the sealing performance is poor due to the splicing and matching problems, and the water stop function cannot be realized. Summary of the Utility Model

[0004] Aiming at the technical problems in the prior art, the utility model provides a foundation pit support structure which is convenient to install, including a plurality of steel pipe piles and steel sheet piles installed between adjacent two steel pipe piles. The side surface of the steel sheet pile is connected with the steel pipe pile through a plurality of connecting components. The plurality of connecting components are arranged at intervals along the length direction of the steel pipe pile. The connecting component includes a fixed ring and a movable ring. The fixed ring is fixedly installed on the surface of the steel pipe pile. The movable ring is slidably installed on the surface of the fixed ring and is locked by a bolt. A connecting block is rotatably installed on the side surface of the steel sheet pile. A T-shaped card slot is arranged on the movable ring. One end of the connecting block away from the steel sheet pile is provided with a T-shaped card block. The T-shaped card block is matched with the T-shaped card slots on the plurality of connecting components.

[0005] Further, a plurality of installation grooves are arranged on the surface of the steel pipe pile. The installation grooves correspond to the fixed rings one by one. The fixed ring is embedded in the installation groove. The bottom surface of the T-shaped card slot is flush with the surface of the steel pipe pile.

[0006] Further, angle scale lines are arranged on the surface of the fixed ring.

[0007] Further, a foundation pit support structure facilitating installation further includes a sealing assembly. The sealing assembly is installed between the T-shaped block and the T-shaped slot. The sealing assembly includes a plurality of telescopic rods and a telescopic sealing strip. The sealing strip is located in the T-shaped slot. Two ends of the sealing strip are respectively fixedly connected to two ends of the plurality of telescopic rods. The sealing strip unfolds or folds under the telescopic action of the plurality of telescopic rods. One end of the telescopic rod is fixedly connected to the surface of the steel pipe pile and is distributed out of alignment with the fixed ring. The other end of the telescopic rod abuts against the T-shaped block.

[0008] Further, the sealing assembly further includes a plurality of springs. The plurality of springs correspond to the plurality of telescopic rods one by one. Blocks are fixedly connected to positions of the telescopic rods close to both ends. The springs are sleeved outside the telescopic rods, and two ends of each spring are respectively fixedly connected to the two blocks.

[0009] Further, the sealing assembly further includes an elastic rubber strip.

[0010] Beneficial effects:

[0011] 1. In the present utility model, through the arrangement of a plurality of connection assemblies including a fixed ring and a movable ring and connection blocks, it is possible to conveniently connect and fix the steel sheet piles and the steel pipe piles, and ensure the structural strength of the connection. Combining the setting that the movable ring is slidably installed on the surface of the fixed ring and the connection block is rotatably connected to the steel sheet pile, it is possible to adjust the angles and deflection positions of adjacent two steel sheet piles, meet the support requirements of foundation pits with different shapes, and at the same time reduce the installation accuracy and improve the installation efficiency. During specific use, first, according to the installation position of the steel pipe pile, select different numbers of connection assemblies to ensure that there are at least two connection assemblies between each steel sheet pile and the steel pipe pile, and at least two connection assemblies are respectively arranged on the upper and lower parts of the steel sheet pile to ensure the connection strength. Then, according to the matching angle between adjacent two steel sheet piles, adjust the positions of the movable rings on the plurality of connection assemblies relative to the fixed rings and fix them with bolts. During this process, if only two steel sheet piles are connected to this steel pipe pile, the four or more movable rings on the steel pipe pile are divided into two groups, the two groups of movable rings are alternately distributed, and the plurality of T-shaped slots on each group of movable rings are on the same vertical line. Finally, the T-shaped blocks on the two steel sheet piles are respectively matched with the T-shaped slots on the two groups of movable rings; during the above process, by rotating the movable ring, the position of the T-shaped slot can be adjusted, so that the included angle between adjacent two steel sheet piles can be adjusted. By rotating the connection block, the distance between adjacent two steel sheet piles can be changed, so that the deflection displacement of the steel sheet pile in the same direction can be adjusted; combining the setting of the T-shaped slot and the T-shaped block can prevent the two from separating and further improve the structural strength of the connection.
