AI Technical Summary

Technical Problem

In existing technologies, splicing between PVC panels can easily lead to fatigue damage, and traditional shallow water road construction is time-consuming and labor-intensive.

Method used

A combined retaining structure using T-shaped sheet pile units and foamed lightweight soil is adopted. The structure is assembled by concave grooves and convex buckles, and foamed lightweight soil is filled inside the plastic steel sheet to form a cofferdam to block water flow. The combined construction of foamed lightweight soil and plastic steel sheet forms a vertical roadbed.

Benefits of technology

It improves the smoothness of the assembly of plastic steel panels and the strength of highway support, is easy to operate, and enhances construction efficiency and the strength of retaining panels.

Abstract

This utility model relates to the field of plastic steel sheet technology and discloses a T-shaped waterproof plastic steel retaining wall for shallow water highways, including a T-shaped sheet pile unit. A first reinforcing plate assembly seat is installed on the left side of the T-shaped sheet pile unit. A concave groove is installed on the left side of the T-shaped sheet pile unit, and a convex buckle is connected to the right side of the T-shaped sheet pile unit. Limiting grooves are formed on both the front and rear sides of the splicing slot, corresponding to the surface of the splicing insert plate. A first limiting plate is inserted into the limiting groove. A second transverse through groove is formed on the inner side of the first reinforcing plate assembly seat. This waterproof plastic steel retaining wall for shallow water highways allows for partial drainage and silt solidification by driving the plastic steel sheet below the silt in the pool and using the snap-fit ​​design of the plastic steel sheet to block water flow. To ensure the strength of the retaining wall, foamed lightweight soil is added to the other side of the plastic steel sheet. The combined construction of the foamed lightweight soil T-shaped sheet pile and the plastic steel sheet pile can improve the required support strength for the highway.
