It is applicable to different tunnel excavation methods. According to the construction needs, the village can build the inverted arch lining with different lengths such as 6 meters, 9 meters and 12 meters to ensure the inverted arch and filling construction quality and construction speed.
The trestle bridge adopts step-by-step walking mode, which can move forward or backward step-by-step in the longitudinal direction of the line, and the whole can move horizontally and be aligned horizontally. The inverted arch is constructed under the main approach bridge, and the trestle bridge can completely retreat to the rear filling area.
