AI Technical Summary

Technical Problem

In existing technologies, during the jacking construction of box culverts, the replacement of test materials requires the use of multiple tools for disassembly and assembly, which increases the replacement time and reduces the efficiency of testing.

Method used

A test bench for simulating the resistance of the side wall of a box culvert jacking was designed. It adopts an electric push rod and a positioning structure to realize the rapid installation and disassembly of the test plate. The electric push rod drives the cross block and positioning column to slide, and combined with rollers and spring clips, it ensures that the test plate is tightly attached to the push plate to prevent displacement and falling off, and enables the rapid replacement of different materials for resistance testing.

Benefits of technology

It improves the efficiency of changing test materials and the speed of disassembly and assembly, ensures test accuracy, enhances the diversity and precision of tests, and reduces test errors.

Abstract

The utility model relates to the technical field of box culvert jacking, and discloses a box culvert jacking side wall resistance simulation test bench, which comprises a test bench body, the upper surface of the test bench body is fixedly connected with two groups of baffles, the inner walls of the baffles are in sliding connection with guide columns, the outer walls of the right sides of the guide columns are fixedly connected with a test plate, and the test plate is fixedly connected with the test bench body. First electric push rods are fixedly connected to the outer walls of the baffles, sliding columns are fixedly connected to the inner walls of the rotating rods, the left ends and the right ends of the sliding columns are slidably connected to the inner walls of the push plates, rolling wheels are rotatably connected to the outer walls of the sliding columns, and the outer walls of the rolling wheels are slidably connected to the inner walls of the push plates. According to the resistance test device, the test plates made of different materials are mounted on the outer wall of the push plate, so that the first electric push rod and the push plate synchronously push the push plate to slide, the arranged test plates can quickly replace different types of materials for resistance test, and the effect of improving the disassembly and assembly and test efficiency is achieved.
