Pipe jacking starting frame supporting system and method for constructing tunnel connection channel

Abstract

The invention provides a pipe jacking starting frame supporting system and method for constructing a tunnel connection channel. The pipe jacking starting frame supporting system comprises a pipeline, the top surface of the outer periphery of the pipeline is fixedly connected with the bottom surface of a supporting box, the top surface of the inner periphery of the pipeline is fixedly connected with the top surface of an induction box, the bottom surface of the periphery of the pipeline is fixedly connected with the top surface of a base box, a first electric cylinder bottom plate is fixed to the lower side surface of the interior of the supporting box, a first electric cylinder is fixed to the upper side surface of the first electric cylinder bottom plate, a first action rod is arranged at the power output end of the top of the first electric cylinder, the top end of the first action rod extends into a main cylinder body, a main piston is fixed to the top end of the first action rod, and pressure liquid is stored in the main cylinder body. According to the technical scheme, the technical problems that in the prior art, intelligent frame plate supporting is not achieved, automatic fire extinguishing cannot be achieved, and flexible movement cannot be achieved are effectively solved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of pipe jacking construction, in particular to a supporting system and method for a starting frame for pipe jacking used in the construction of tunnel communication passages. Background technique [0002] At present, most of the connecting passages of subway tunnels and municipal highway tunnels adopt the method of underground excavation. In areas where groundwater is relatively abundant, civil engineering subterranean excavation methods are basically limited to frozen mine subsurface excavation. However, the freezing method has unfavorable factors such as long construction period, great environmental impact, and high risk. Related accidents are common and the consequences are serious. With adverse consequences such as frost heaving and thawing caused by deep underground freezing, it is increasingly difficult to adapt to urban core areas with complex geological conditions and high environmental protection r...
