That is to say, the main body of the steel sheet pile is composed of the main board and the side panels on both sides, and the overall cross-section between the main board and the side panels is trapezoidal, and ribbed plates are installed on the outside of the side panels, on the one hand, to increase the contact area of the steel sheet pile when inserted into the soil layer of the foundation pit slope, and on the other hand, the ribbed plates between the adjacent steel sheet piles are welded together to form a cone, which can improve the stability of the steel sheet pile inserted into the soil layer of the foundation pit slope.
[0023] Furthermore, if Figure 1 As shown, a structural plate 14 is welded on the ribbed plate 13, and an inclined notch 15 is provided at the end of the ribbed plate 13, so as to neatly weld the side plates of two adjacent steel sheet piles 1. That is, in order to improve the structural strength of the ribbed plate, a structural plate of a steel plate is welded on the ribbed plate; at the same time, a smooth and inclined notch is provided at the end of the ribbed plate, so that when welding two adjacent steel sheet piles, the smooth notch is used for smooth butt jointing, which is beneficial to the subsequent welding operation and the connection stability between the two steel sheet piles after welding.
[0024] Furthermore, if Figure 1 As shown, the angle between the main board 11 and the side board 12 is 120°-160°, and the angle between the side board 12 and the ribbed board 13 is 30°-75°. That is to say, in this embodiment, the side board is inclined in a direction away from the main board, and the angle formed between the side board and the main board is 120°. At the same time, one end of the ribbed board is fixedly connected to the end of the side board, and the ribbed board is located outside the side board and inclined in a direction away from the side board. At this time, the angle formed between the ribbed board and the side board is 45°.
[0025] It should be noted that, in this embodiment, the main board 11, the side board 12 and the ribbed board 13 are an integrally formed structure.
