Abstract

An assembled trolley for tunnel shield segment support and a method of using the same, comprising a movable chassis, a supporting arch, a hydraulic support system, a slide rail and a traction frame; the arches supporting the arch are arranged across the left and right On the two main beams, the hydraulic jacks of the hydraulic support system are arranged vertically on the outer surface of the arched frame, the bottom of which is fixedly connected to the arched frame through the mounting seat, and the top is provided with rubber gaskets in contact with the shield segment; At the bottom of the dome; a transport hook is arranged in the downwardly opening rail of the sliding rail; the traction frame is a horizontal frame beam fixed on one end of the movable chassis, and is connected with the traction equipment to drive the trolley to move. The invention is simple in structure and convenient in construction. The radially arranged jacks provide necessary support for the shield segment, the jacks can be freely replaced according to different pressures, and the support strength meets the design requirements; the traction device and the chassis are connected by cross pieces to avoid The main force-bearing components are locally deformed, and the components can be replaced at any time, with strong adaptability.

Description

technical field [0001] The invention belongs to the technical field of tunnel engineering construction, and in particular relates to an assembled trolley for supporting tunnel shield segments and a method of using the same. Background technique [0002] With the expansion of urban scale and the rapid development of urban construction in China, the status of urban underground transportation is prominent, and more and more cities are participating in the construction of urban underground transportation. In the construction of tunnel engineering, the shield method is generally used for construction, which is a fully mechanized construction method in the construction of the underground excavation method. To prevent the collapse into the tunnel, at the same time, use a cutting device to excavate the soil in front of the excavation front, transport it out of the hole through the excavation machine, pressurize it at the back with a jack, and assemble the precast concrete segments t...
