Tunnel trolley walking tool and construction method

Abstract

The invention provides a tunnel trolley walking tool and a construction method. The tunnel trolley walking tool comprises a main machine, wherein the main machine is connected with a trolley, the trolley is connected with a connection bridge, a rear hoisting system is arranged on the connection bridge, the trolley walks on a moving track skeleton, a walking duct piece conveying device is arrangedon the moving track skeleton, and a front hoisting system is arranged on the main machine. The construction method includes the following steps that a, the rear hoisting system hoists the last sectionof the moving track skeleton to the duct piece conveying device; b, the duct piece conveying device conveys the last section of the moving track skeleton to the lower portion of the front hoisting system; c, the front hoisting system hoists the last section, located on the duct piece conveying device, of the moving track skeleton, to the place ahead the most front section of the moving track skeleton; d, the trolley moves forwards on the moving track skeleton. The tunnel trolley walking tool has the advantages of solving defects of unbalance loading, severe trolley deformation and the like which exist in heavy loading swerve conditions of the trolley, improving construction safety and efficiency, and simultaneously using the trolley walking track (the moving trac skeleton) simple in structure, convenient to operate and construct, recyclable, and capable of saving construction cost.

Description

technical field [0001] The invention relates to tunnel excavation, in particular to a traveling tool for a tunnel trolley and a construction method. Background technique [0002] With the development of the city, the construction of large-diameter railway and highway tunnels in the urban underground space has become a trend. Tunnels such as "single-hole, double-track" and "double-deck, multi-lane" have put forward new requirements for the construction equipment of super-large-diameter tunnels. Therefore, super-large-diameter Earth pressure and mud-water shields play an increasingly important role in urban underground space construction. Compared with conventional shield tunneling machines, the design and construction methods of ultra-large diameter shield tunneling machines urgently need continuous innovation and optimization. [0003] At present, the No. 1 trolley of the supporting system behind the ultra-large-diameter shield machine (excavation diameter ≮12m) has a lot o...
