Abstract

The invention provides an assembled shield / TBM complete machine empty-pushing counter-force device and an application method thereof. The device comprises an abutting plate, a device base, a supporting plate, an inserting rod capable of being inserted into a preformed hole, a profile steel support and a profile steel. The application method comprises the following steps: 1, assembling the device; 2, forming reserved holes; 3, hoisting the abutting plate, the device base and the profile steel support to a plane guide table, and the step 4 and other steps The device and the application method thereof are convenient to disassemble and assemble, easy to operate and stable in structure, and the problems that an original split air-pushing station-crossing operation is high in risk and low in efficiency, and an overall air-pushing reaction frame is insufficient in strength, unstable in structure, heavy and the like are solved.

Description

technical field [0001] The invention relates to the technical field of shield machine auxiliary tools and its application, in particular to an assembled shield / TBM complete machine idle thrust counter force device and its application method. Background technique [0002] At present, in the tunnel construction process of shield tunneling machine / TBM (hereinafter referred to as TBM), most of the existing TBM air push passing technologies are split empty push passing, that is, the main machine and the supporting trolley pass through separately, and the passing through separately There are slow passing speeds, high construction risks, and heavy manual loads, which restrict the overall construction progress and increase construction costs. However, the overall passing of the station requires a greater demand for empty push reaction force. The strength and stability of the reaction force device must be guaranteed, otherwise it cannot be provided. Sufficient reaction force makes it...
