Description

A simple slope protection structure for steel sheet piles Technical Field

[0001] This utility model relates to the field of slope protection technology, specifically a simple slope protection structure for steel sheet piles. Background Technology

[0002] In fields such as building construction, foundation pit support, and water conservancy projects, steel sheet piles are often used as temporary or permanent support structures. For slopes requiring excavation, a retaining plate is usually installed on one side of the steel sheet piles to prevent soil slippage. In existing technologies, the connection between steel sheet piles and slope retaining plates is mostly achieved through on-site welding or simple bolt fixing. This is not only cumbersome and inefficient to install, but also difficult to adjust flexibly according to the actual slope gradient and height. In addition, traditional connection structures have poor stability and are prone to loosening or deformation under soil pressure, affecting the support effect and construction safety.

[0003] In view of this, and in response to the above problems, this case provides a simple slope protection structure for steel sheet piles that solves the problems of cumbersome installation, low efficiency, and difficulty in adjusting according to the actual slope gradient and height. Summary of the Invention

A threaded sleeve is installed at the bottom end of the connecting plate, and a compression screw is movably embedded in the threaded sleeve. One end of the compression screw is in contact with the front wall of the sheet pile assembly. An adjustable connector is installed at the top of the mounting frame.

The connecting screw movably passes through one of the fixing holes. A fixing rod is installed on the other side of the connecting frame, and five positioning holes are evenly distributed on the upper end of the fixing rod.

[0011] This utility model provides a simplified slope protection structure for steel sheet piles, which has the following advantages: the combination of hangers, crossbars and slope protection plate fixers enables rapid assembly of steel sheet piles and slope protection plates without on-site welding, greatly improving construction efficiency. The slope protection plate fixer uses an adjustable connector, and its fixing plate has multiple fixing holes.
