A multi-ring segment tunnel test unit synchronous transport system and method

Abstract

The invention discloses a synchronous transport system and method for a multi-loop segment tunnel test unit. The synchronous transport system for the multi-loop segment tunnel test unit is characterized by comprising a multi-loop segment horizontal synchronous transport device and a multi-loop segment synchronous lifting device, the multi-loop segment horizontal synchronous transport device comprises a synchronous transport platform base, the synchronous transport platform base is provided with two horizontal support beams which are parallel to each other, guide grooves are arranged in the horizontal support beams, transport beams and V-shaped roller pairs are arranged in the guide grooves, the transport beams are inclined, the V-shaped bottoms of the transport beams are bonded and supported on rollers, and first hydraulic servo cylinders are arranged at the tail ends of the transport beams; the multi-loop segment synchronous lifting device comprises a lifting frame and a plurality ofsecond hydraulic servo cylinders, the lifting frame is positioned directly in front of the horizontal support beams and the upper surface of the lifting frame can be folded with the bottom of the multi-loop segment test unit, and the second hydraulic servo cylinders are distributed around the bottom periphery of the lifting frame. The synchronous transport system for the multi-loop segment tunneltest unit has the advantage of effectively avoiding accidental deformation and damage of the multi-loop segment tunnel test unit during horizontal and vertical transport process.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a multi-ring segment tunnel test unit synchronous transport system and method. Background technique [0002] The multi-ring segment test unit is a multi-ring structure formed by splicing segments to simulate the real tunnel segment structure state. It needs to be transported non-destructively and smoothly into the multi-ring segment soil in the comprehensive test platform of the shield tunneling method. The soil pressure loading position is simulated in the pressure simulation system, and the multi-ring segment test unit is a large fragile thin-walled member with the characteristics of uncontrollable deformation, safety, and destructibility. Therefore, the level and During vertical transportation, its damage cannot be ignored, and the displacement cannot be precisely controlled.
