Problems solved by technology

The dragging method in the prior art has the problems of complex devices, poor structural stability and easy failure. The inventors found that when the shield machine host is dragged in the primary branch tunnel of the mine, it faces difficult problems such as limited dragging space, heavy host weight and turning of the host machine. Therefore, once the towing device fails during the construction process, it will lead to the failure of the shield main machine to pull, increase the construction risk, and delay the construction progress.

Abstract

The invention discloses a drag device and a drag method of a tunnel internal shield main engine. The problem that the dragging of the shield main engine in the prior art is easy to fail work is solved; and the drag device of the tunnel internal shield main engine has the beneficial effects that the shield main engine is effectively dragged and can be repeatedly used. The specific scheme is that the drag device of the tunnel internal shield main engine comprises at least one pair of drag parts; the drag parts are symmetrically placed on the two sides of a guide platform in a tunnel; each drag part comprises a steel strand, a reaction frame, a reserved plate and a drag piece, wherein one end of the steel strand can be detachably connected with the shield main engine; a hole for the steel strand to penetrate through is formed in the reaction frame; multiple reserved plates are arranged in the length direction of the guide platform in the tunnel; the reserved plates and the reaction framecan be detachably connected with each other; the end part of the drag piece can abut against the reaction frame and can be supported by the guide platform; and the drag piece drags the steel strand penetrating through the hole so as to drag the shield main engine.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a pulling device and a pulling method for a shield main machine in a tunnel. Background technique [0002] With the acceleration of urbanization in our country, cities are facing problems such as the shortage of available space on the ground and the increase in demand for underground transportation. Shield method construction has the characteristics of high excavation efficiency, less disturbance to the surrounding environment, and advanced and reliable machinery. At this stage It is widely used in underground tunnel construction. In the subway tunnel project, after the initial support construction of the tunnel, sometimes in order to complete the docking and penetration of different construction sections, the main engine (cutter head, front shield, middle shield and tail shield) of the shield machine and the supporting trailer are detached. Basically, the main engine part nee...
