A mobile trolley for drilling based on tbm method for tunnel construction

Abstract

A mobile drilling trolley for tunnel construction based on the TBM method. The trolley runs along the tunnel track. The top surface of the trolley is fixed with a plurality of horizontally arranged I-shaped steel door frames, and the adjacent I-shaped steel doors The brackets are adjustable and connected with supporting shafts arranged vertically; the supporting shafts are adjustable in angle and connected with drilling execution units; the drilling execution units include guide grooves, outrigger cylinders and pneumatic drills, wherein the guide grooves are set horizontally, and the guide grooves The bottom is connected with the support shaft, the top of the guide groove is open, and the outrigger cylinder is fixed axially in the guide groove; the end of the piston rod of the outrigger cylinder is fixedly connected with the inner wall of the guide groove, and the middle part of the cylinder barrel of the outrigger cylinder penetrates the guide groove The side wall, and the end of the cylinder barrel of the outrigger cylinder is axially fixed to the pneumatic drill. The mobile trolley effectively solves many problems in tunnel construction, effectively reduces scaffold erection and relocation procedures, saves labor and speed of drilling during the drilling process, reduces construction costs, and improves construction safety.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a mobile drilling trolley for tunnel construction based on the TBM method. Background technique [0002] During the construction of TBM tunnels, surrounding rock reinforcement and water blocking shall be carried out in accordance with the design requirements for tunnel sections with unfavorable geological conditions and water leakage tunnel sections after tunnel lining. Among them, in the construction of consolidation grouting and curtain grouting, hole wall drilling accounts for a large proportion of work , Drilling work efficiency directly affects project cost and project progress. [0003] In the TBM construction tunnel, the top arch of the tunnel occupies the air duct, the side arch occupies the cables and pipes, there is also a belt fuselage in the tunnel where the belt conveyor discharges slag, and the bottom arch is equipped with locomotive tracks for...
