Abstract

The invention provides a shield tunnel prefabricated box culvert piece fine adjustment and assembly device which solves the problem that time and labor are wasted during butt joint of prefabricated box culvert pieces, guarantees the assembly quality of the prefabricated box culvert pieces and comprises a vehicle body, a stepping device, a telescopic device and a fine adjustment assembly. The vehicle body is of a long structure distributed in a front-back extending mode and can move front and back in a culvert of the prefabricated box culvert piece. The fine adjustment assembly is installed at the front end of the vehicle body and comprises a box culvert piece supporting plate, and the box culvert piece supporting plate is used for lifting the culvert top of a prefabricated box culvert piece and finely adjusting the position of the prefabricated box culvert piece; the stepping device is installed on the vehicle body in a matched mode and can move back and forth in the front-back direction, the stepping device comprises a left stepping supporting shoe and a right stepping supporting shoe which are symmetrically distributed, and the two stepping supporting shoes are used for fixedly supporting the left side wall and the right side wall of a culvert of the prefabricated box culvert piece. One end of the telescopic device is connected to the front end of the vehicle body, and the other end of the telescopic device is connected to the stepping device.

Description

technical field [0001] The invention relates to the technical field of splicing prefabricated box culverts of shield tunnels, in particular to a finely adjusted and assembled device for prefabricated box culverts of shield tunnels. Background technique [0002] During the construction of large-diameter shield tunnels, it is usually necessary to lay box culverts at the bottom of the tunnel as drainage channels or emergency escape channels for personnel. The construction steps of box culverts are relatively cumbersome. slow. In order to improve construction efficiency, the method of simultaneous construction using prefabricated components (segments, box culverts and partition walls) has become the mainstream. [0003] There is a culvert in the middle of the prefabricated box culvert, the top is a plane, and the bottom is an arc-shaped surface. The assembly method of the prefabricated box culvert is hoisting and splicing. Generally, the tunnel boring machine and Bottom arch a...
