Abstract

The invention discloses an assembly type trolley used for tunnel shield segment support and a using method thereof. The assembly type trolley comprises a movable chassis, a supporting arch frame, a hydraulic support system, a slide rail and a pull frame, wherein an arched frame of the support arch frame is spanned on left and right main beams; a hydraulic lifting jack of the hydraulic supporting system is perpendicular to the outer surface of the arched frame; the bottom of the hydraulic support system is fixedly connected to the arched frame through a mounting base; the top of the hydraulic support system is provided with a rubber gasket which is in contact with a shield segment; the slide rail horizontally penetrates through the bottom of the arch top in a longitudinal direction; a transporting hanger is arranged in a rail with a downward opening of the slide rail; the pull frame is a horizontal framework beam which is fixed to the end part of one side of the movable chassis; and thehorizontal framework beam is connected to pull equipment to drive the trolley to move. The assembly type trolley can freely replace the lifting jack according to different pressure, and enables supporting strength to meet design requirements; and a pull device is connected to the chassis through a cross part, so that a main stress component is prevented from local deformation, and the component can be freely replaced, and therefore, the assembly type trolley is strong in adaptability.

Description

Technical field [0001] The invention belongs to the technical field of tunnel engineering construction, and specifically relates to an assembled trolley used for tunnel shield segment support and a use method thereof. Background technique [0002] With the expansion of the scale of Chinese cities and the rapid development of urban construction, 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, shield construction is generally adopted, which is a fully mechanized construction method in undercut construction. It pushes the shield machinery in the ground and supports the surrounding rocks through the shield shell and segments. To prevent collapse into the tunnel, at the same time, excavate the soil with a cutting device in front of the excavation, transport it out of the tunnel by the excavation machinery, press the jack at the bac...
