Abstract

The embodiment of the invention provides a shield starting base. The shield starting base comprises a supporting structure, shield machine guiding structures and shield machine moving structures, a shield machine accommodating groove is formed in the supporting structure in the axis direction of a tunnel, and a reaction frame accommodating groove is formed in the direction perpendicular to the tunnel axis; the shield machine accommodating groove is vertically arranged with the reaction frame accommodating groove to divide the supporting structure into two front supporting bodies and two rear supporting bodies, and the sides, close to the shield machine accommodating groove, of the two front supporting bodies and the two rear supporting bodies are in chamfered shapes; the shield machine guiding structures are symmetrically arranged on the chamfered surfaces of the two front supporting bodies and the two rear supporting bodies in the tunnel axis direction; and the shield machine moving structures are symmetrically arranged on the upper surfaces of the two front supporting bodies and the two rear supporting bodies in the tunnel axis direction. The shield starting base can reduce the construction cost and work quantity, the construction period can be shortened, and the supporting force to a shield machine can be improved.

Description

technical field [0001] The invention relates to the field of municipal engineering construction, in particular to a shield starting base and a shield starting method. Background technique [0002] With the rapid development of my country's urban rail transit construction and the gradual increase in the utilization rate of underground space, major cities have joined the ranks of subway construction. Features and advantages, more and more extensive promotion and application. [0003] In the prior art, when the shield machine is starting, it is necessary to erect a steel structure starting bracket between the launching shaft and the end wall, erect the shield machine on the starting bracket, and then install the shield machine behind the shield machine. Install the reaction frame at the bottom and start the shield machine; after the shield excavation is completed, remove the starting bracket. If there is a problem in the assembly of the starting bracket, it will affect the sup...
