Construction device and method for channel between existing underground space and shield tunnel

Abstract

The invention relates to a construction device for a channel between an existing underground space and a shield tunnel. The construction device comprises two rows of parallel stand columns corresponding to the set positions of the channel and erected on a bottom plate of the underground space, and height adjusting assemblies installed on the stand columns and capable of moving up and down along the stand columns, wherein each height adjusting assembly is provided with a first clamp, the top end of a pipe joint is clamped through each first clamp to enable the pipe joint to be fixedly connectedto the corresponding height adjusting assembly, downward pressure is applied to the pipe joint through downward movement of each height adjusting assembly to press the pipe joint into a soil body, the height adjusting assemblies can drive the pipe joint to descend synchronously, so that the sinking depth of the pipe joint is controlled conveniently, and the problems that the position of the pipejoint deviates and the stress performance of the pipe joint is poor due to sudden sinking of the pipe joint are solved.

Description

technical field [0001] The invention relates to the field of building technology, in particular to a construction device and a construction method for a channel between an existing underground space and a shield tunnel aimed at a narrow existing underground space. Background technique [0002] The construction of urban roads and rail transit in the urban core area usually adopts shield tunneling method. Shield tunnels are generally separated by a certain distance and need to establish a spatial connection with the ground to meet the requirements of ventilation, wiring, and maintenance. Since the construction of urban roads and rail transit in the urban core area is generally later than the construction of ground buildings, shield tunnels generally need to pass through ground buildings, resulting in no space on the ground for construction of enclosure structures to build vertical connection passages between shield tunnels and the ground . At present, small pipe joints are u...
