Abstract

The invention discloses a needle beam type inverted arch lining sliding framework and a construction method thereof. The needle beam type inverted arch lining sliding framework is characterized in that needle beam support leg assemblies (2) are arranged at two ends of a needle beam assembly (1); a needle beam frame (3) is arranged in the middle of a needle beam (1); the lower part of the needle beam frame (3) is connected to an inverted arch template (4); a travelling device (5) is also arranged on the needle beam frame (3); a pulley (1-1), a winch installation position (1-1) and a track (1-3) are arranged on the needle beam (1); and a support wheel (3-1) and an electric hoist support base (3-2) are arranged on the needle beam frame (3). The method comprises the following steps of: (1) taking the needle beam assembly (1) in place; (2) taking the needle beam frame (3) in place; (3) taking the inverted arch template (4) in place, namely shuttering; (4) demoulding; (5) turning to the steps two and three; (6) travelling the needle beam assembly (1); (7) turning to the step four; and completing one working cycle.

Description

technical field [0001] The invention relates to a needle-beam type inverted arch lining sliding formwork for construction of an inverted arch concrete lining in a passenger dedicated line tunnel and a construction method thereof. Background technique [0002] At present, my country has entered the era of large-scale construction of high-speed railways and highways. Due to the tight construction period, especially the high requirements for post-construction settlement of passenger dedicated line tunnels and strong structural integrity, during the construction process, the inverted arch concrete lining needs to be poured at one time. According to Practical experience in the construction process shows that using small pieces of steel formwork for inverted arch lining formwork construction not only leads to installation in place and slow demoulding speed due to complex construction procedures, but also low construction efficiency, high labor costs, and many factors affecting const...
