Abstract

The invention relates to a lining method for tunnel emergency turnout strips and a tunnel-lining trolley. The lining method divides the tunnel-lining trolley into a left tunnel-lining trolley and a right tunnel-lining trolley which have independent travelling mechanisms, the left tunnel-lining trolley and the right tunnel-lining trolley are respectively driven into a main tunnel, auxiliary tunnel traveling tracks are transversely laid, the trolleys are jacked by jacks, the travelling mechanisms of the jacked trolleys are rotated by 90 degrees and mounted, the left and the right trolleys travel to the lining positions of auxiliary tunnels of the emergency turnout strips, and are connected, the lining method can quickly assemble lining formworks in the smaller tunnel space, consequently, the lining speed is increased, and the lining quality is guaranteed. The tunnel-lining trolley for carrying out the method can be divided into the left and the right trolleys with the independent travelling mechanisms, and two top formworks (5, 4) and two side formworks (9, 10) are arranged between the left and the right trolleys; gantries (1) and brackets (2) of the left and the right trolleys are detachably connected, and the travelling mechanisms (16) of the left and the right trolleys can be rotated by 90 degrees and assembled.

Description

technical field

[0001] The invention relates to a lining method for a tunnel emergency avoidance zone and a tunnel lining trolley for realizing the method. Background technique

[0002] Along with the large-scale construction of high-speed railways and expressways in my country, construction units have higher and higher requirements for construction equipment. In order to avoid accidents in tunnels and hinder the entire traffic, known expressway tunnels are provided with emergency avoidance belts. The road surface of the highway emergency avoidance zone is several meters wider than that of the main tunnel, so the radius of the emergency vehicle avoidance belt lining trolley is larger than that of the main tunnel lining trolley.

[0003] Chinese utility model patent CN201031705Y discloses a special lining trolley for railway tunnels, which includes an arched mold formed by two-sided molds, a door frame, several jacks supporting the two-sided molds, and a running mechanism, bu...
