and a clamping groove 4 is formed between the adjacent buckles 2, and the width of the clamping groove 4 is matched with the thickness of the wing plate 3.
When the continuous-row buckling-section reinforced steel sheet pile supporting structure is used for supporting, the wing plates 3 and the buckles 2 of the two adjacent supporting structures 5 are oppositely arranged, so that the wing plate 3 of one supporting structure 5 can be buckled in the buckling groove 4 of the other supporting structure 5. Further, each supporting structure 5 comprises a plurality of buckles 2, so that a plurality of clamping grooves 4 can be formed, the positions of the wing plates 3 can be adjusted according to the requirements of the size of a construction site and the supporting rigidity during use, the strength of supporting systems formed by buckling at different positions is different, and the structural flexibility is high. According to the form, a plurality of supporting structures 5 are used, so that a continuous supporting system with adjustable rigidity can be formed, the combined stress is achieved, and the load effect of soil outside the pit after the foundation pit is excavated is jointly born.
As shown in fig. 2, the two supporting structures 5 in the forward direction (upward direction) in fig. 2 may be close to each other, so that the wing plates 3 are inserted into the clamping grooves 4 in the middle of the supporting structures 5 in the reverse direction (downward direction), and the density between the supporting structures 5 is greater, so that the strength is greater, whereas the strength is relatively smaller when the supporting structures 5 are sparse, and when in use, the supporting structures 5 can be adjusted in corresponding positions according to geological conditions of the stratum engineering, so that the method can be suitable for foundation pits in different geological conditions. In addition, the cross-sectional area of the supporting structures 5 after being buckled with each other is smaller (the cross-sectional area is reduced by nearly one time compared with the traditional structure), the occupied space is smaller, the use ratio of the engineering site is effectively improved, and the use scene is expanded.
The continuous-row buckle-section reinforced steel sheet pile supporting structure is simple in structure, easy to form standard components for mass production, and high in structural flexibility, and the positions of the wing plates 3 can be adjusted according to the requirements of the construction site and the supporting rigidity.
For easy disassembly and assembly, the height of the wing plate 3 is larger than that of the buckle 2, namely the vertical distance between the top end of the wing plate 3 and the steel pile 1 is larger than that between the top end of the buckle 2 and the steel pile 1. This kind of form for have the space between the pterygoid lamina 3 of two adjacent supporting construction 5, be convenient for dismouting, and pterygoid lamina 3 and shaped steel pile 1 contact each other, increased the holding power between each other, further strengthened the rigidity of supporting system.
