[0004] Traditional wood support: a simple support structure is built with wood, which has low cost. However, the strength of wood is limited, and it is prone to deformation and breakage under high soil pressure, which cannot effectively prevent collapse, and wood is prone to rot due to moisture, with short service life.

[0005] Steel support: steel has high strength, but professional equipment is required for installation, which is complex to operate and costly. At the same time, improper handling of the connection nodes of steel can lead to a decrease in overall stability, and it is difficult to respond quickly and provide reliable support in the face of sudden soil displacement, with limitations in anti-collapse ability.

[0006] Soil nailing wall support: soil nails are implanted into the soil and concrete is sprayed to form a support structure. This method has a long construction period and has certain requirements for soil properties, and it is not effective in high-moisture or loose soil, and it is difficult to remove later, and the repair cost is high if collapse occurs.

[0007] Therefore, it is of great practical significance to develop an assembly type support device that is easy to install, cost-effective and can effectively prevent trench collapse. INVENTION CONTENTS
