Abstract

The invention provides a special trolley for fast transferring in a tunnel widening section and a construction method, and relates to the field of civil engineering construction equipment. The trolley solves the problems that the spatial size of the inner contour of an existing emergency parking strip differs greatly from the size of a whole section of a tunnel, overall pouring of the position of the parking strip cannot be conducted by a secondary lining trolley by using a traditional craft. A supporting mechanism is hinged to the inner surface of a housing through a plurality of screw rods, and the bottom end of the supporting mechanism is provided with a driving mechanism; one end of a top part template is hinged to one end of a first side part template, and the other end of the top part template is hinged to one end of a second side part template; and the two ends of a cross beam of the supporting mechanism are correspondingly provided with longitudinal supporting arms, the bottom ends of the longitudinal supporting arms are connected with one end of a heightening box, the other end of the heightening box is connected with the driving mechanism, widening frames are arranged at the centers of the outer sides the longitudinal supporting arms, the upper surface of the cross beam is evenly provided with two oil cylinders, and the output ends of the two oil cylinders are fixedly connected with the top template. The special trolley is suitable for construction of the tunnel.

Description

technical field [0001] The invention relates to the field of civil engineering construction equipment, in particular to a trolley specially used for rapid transition of a tunnel widening section and a construction method. Background technique [0002] The section tunnel in China is provided with a total of 12 sections on the left and right sides of the emergency parking belt (widening section), each section is 50 meters long. Set up an emergency parking belt every 750 meters on the right side of the tunnel driving direction, with a width of 4 meters and a length of 50 meters (including the 2.5×5M transition section). [0003] From the perspective of safety, emergency parking belts are set up in the extra-long tunnels of expressways in our country. Due to the large difference between the space size of the inner contour of the emergency parking zone and the size of the overall section of the tunnel, the secondary lining trolley cannot directly pour the position of the parking...
