Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically a trench quick-release anti-collapse support device. Background Technology

[0002] In pipeline construction and maintenance, workers often need to operate in narrow and geologically complex trenches. These trenches are highly susceptible to collapse due to variable geological conditions, tight schedules, and external environmental factors, seriously threatening the safety of workers. Existing support methods mostly employ traditional support structures such as wooden planks, steel plates, or reinforced concrete supports. These methods are not only time-consuming and labor-intensive to install and dismantle, but also difficult to adapt to rapidly changing geological conditions, causing significant inconvenience and safety hazards during construction. Therefore, designing a quick-release trench collapse-prevention support device that can be quickly disassembled and installed, effectively supports both sides of the trench, and ensures construction safety through force transfer is an urgent practical need and has significant application value.
