Rail type adjustable and comprehensive trolley for tunnel section

Abstract

The invention discloses a rail type adjustable and comprehensive trolley for a tunnel section. The trolley is simple in structure and facilitates construction. The trolley comprises a rack mechanism, a section contour rechecking mechanism, a walking mechanism and an operation platform mechanism. The section contour rechecking mechanism is installed on the periphery of the rack mechanism. The walking mechanism is installed at the bottom of the rack mechanism. The operation platform mechanism is installed on the rack mechanism, so that tunnel second-lining construction section rechecking, reinforcing steel bar positioning and sample frame functions, waterproof material laying and positioning, and primary support second-lining concrete grouting platform and second-lining defect processing platform functions are achieved. The excavation contour of the tunnel section can be rechecked so as to ensure the standardability of the excavation contour of the tunnel section, the bending radian of top arch contour ribs and side wall contour ribs can also be changed, and the rail type adjustable and comprehensive trolley is applicable to section rechecking and waterproof construction of tunnels of different sections, and particularly suitable for different support sections which are adopted for the same tunnels due to different surrounding rock grades.

[0002] There are two typical representatives of domestic tunnel trolleys, one is a separate steel bar trolley, a typical representative is "Construction Method for Installing Tunnel Arch Reinforcement Bars with Adjustable Positioning Device Reinforcement Trolleys" compiled by Wu Shenghong, the third company of China Railway 23rd Bureau Group ([ 1] Wu Shenghong. Construction method for installing steel bar in tunnel arch with adjustable positioning device steel trolley [J]. Science and Technology Information Development and Economics, 2008, 16); the other is the front trolley connected with the second lining car, its typical Representatives such as the reinforced steel formwork trolley used by China Water Conservancy and Hydropower Seventh Engineering Bureau Co., Ltd. at the end of Xiluodu 2# flood discharge tunnel. Their structures are relatively bulky, their functions are too single, and their design is not humanized enough.
