Problems solved by technology

If U-shaped steel sheet piles with larger specifications are used, it is not only uneconomical, but also inconvenient for construction due to a large increase in weight and volume, and higher requirements for lifting and surrounding construction environments.

Embodiment Construction

[0027] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. What needs to be declared here is that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features and technical means involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0028] Such as figure 1 As shown, the hot-rolled U-shaped steel sheet piles of the present invention include several pile bodies 1 of hot-rolled U-shaped steel sheet piles with curling 2 on both sides. Fasten with curl 2. The present invention still adopts traditional smaller-sized hot-rolled U-shaped steel sheet piles such as PU400X170 hot-rolled U-shaped steel sheet piles. A number of two adjacent hot-rolled U-shaped steel sheet piles h...

Abstract

The invention discloses a hot-rolled U-shaped steel sheet pile. The hot-rolled U-shaped steel sheet pile comprises a plurality of pile bodies of the hot-rolled U-shaped steel sheet pile, wherein the pile bodies are provided with turned edges on both sides; grooves in the two adjacent pile bodies face the opposite directions, and the turned edges of the two adjacent pile bodies are buckled; a pre-stressed steel strand is mounted in the groove of each pile body of which the groove faces the excavation side; an anchoring device provided with a first vertical hole is arranged at the bottom end of the pile body in the groove; a tensioning and anchoring device provided with a second vertical hole is arranged at the top end of the pile body; at least one supporting device is arranged at the middle of the pile body in the groove along the vertical direction; a guiding sleeve provided with a sliding hole is arranged on each supporting device; through the guiding sleeve, the pre-stressed steel strand can slide along the vertical direction; and the vertical distance between the center of the sliding hole and the inner wall of the groove is greater than that between the centers of the vertical holes in the bottom-end and top-end anchoring devices and the inner wall of the groove. Not only can the hot-rolled U-shaped steel sheet pile disclosed by the invention be conveniently and rapidly constructed when being embedded in soft soil, but also the relatively great flexural capacity can be achieved.

Description

technical field [0001] The invention relates to the technical field of civil engineering construction, in particular to a hot-rolled U-shaped steel sheet pile. Background technique [0002] In the support structure of building foundation pits, in addition to the commonly used reinforced concrete piles, there are also hot-rolled steel piles such as hot-rolled I-shaped piles, or rotary jet cement mixing piles with water-stopping effects embedded in shaped steel such as I-shaped steel or grooves. The steel support and water-stop integrated pile is the SMW construction method pile. [0003] For soft soil foundations, when the excavation depth of the foundation pit is relatively shallow, such as 10-15 meters, hot-rolled U-shaped steel sheet piles are also used. Since both sides of the U-shaped section of the hot-rolled U-shaped steel sheet pile have curling edges, two hot-rolled U-shaped steel sheet piles can be buckled together, which not only plays a connecting role, but also ...
