Description

Technical Field

[0001] This utility model relates to the field of trench support technology, and in particular to a detachable trench anti-collapse device. Background Technology

[0002] Pipeline trench anti-collapse devices are engineering equipment or structures used to protect the safety of underground pipeline construction and prevent trench collapse. When laying aviation fuel pipelines, trenches need to be excavated, and the stability of the trenches directly affects the safety of construction workers and the smooth progress of the project.

[0003] In existing technologies, trench anti-collapse devices are usually hoisted and placed in partially excavated trenches using hoisting equipment. The trench anti-collapse devices need to be stably supported inside the trench. However, existing trench anti-collapse devices are usually a single integrated structure. The installation process using hoisting is too cumbersome and inconvenient to disassemble. Furthermore, they cannot be adjusted according to the width of the trench, resulting in low practicality.
