Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, in particular to a green construction equipment applied to rail transit. BACKGROUND

[0002] Tunneling accidents such as collapse may occur during construction. Collapse is an uncontrollable disaster that causes tunnel surrounding rock and support surface to collapse during tunnel construction. Drilling and blasting is a common method of tunnel construction, and the probability of construction collapse is high. The high frequency and high risk of construction collapse seriously threaten the safety of engineering equipment and personnel. Currently, measures such as excavating collapse bodies or preventing steel pipes are taken to rescue trapped personnel, but this method is not suitable for large-area collapse rescue. Due to the unsatisfactory tunnel collapse rescue measures, the cost is high, the construction is complex, and the excavation and construction of the tunnel are greatly disturbed. A solution is needed to solve the above technical problems.

[0003] As disclosed in patent document CN213478357U, the device uses a support vertical plate as a lateral support structure of the device structure, and the embedded connection between the bottom and the support bottom plate effectively enhances the compressive resistance and stability of the device structure. The reinforcing plate is inclined to form a triangular angle with the support vertical plate, and the support vertical plate is reinforced from the inside. The "Z" shape effectively disperses external forces.

[0004] However, the above-mentioned support structure needs to be punched before use. When punching the support structure in the tunnel, the top of the inner wall of the tunnel is prone to falling debris or dripping sewage, affecting the punching efficiency of the support structure. At the same time, due to the poor air circulation inside, the dust generated during construction in the tunnel will affect the environment inside the tunnel and have adverse effects on the health of the construction workers inside.
