Shield tunneling machine counter-force system and construction method thereof

Abstract

The invention relates to a shield tunneling machine counter-force system and a construction method thereof. The shield tunneling machine counter-force system comprises arc-shaped abutting blocks, a pair of bases, stand column assemblies, telescopic pieces and cross beams, wherein the arc-shaped abutting blocks are assembled between a main body structure and a shield tunneling machine, and when the shield tunneling machine is close to a side wall corresponding to the main body structure, an assembling gap is formed between the shield tunneling machine and the arc-shaped abutting blocks; the pair of bases is spliced at the assembling gap; the stand column assemblies are rotatably connected to the bases; the telescopic pieces are obliquely supported between the stand column assemblies and the bases; and the cross beams are detachably connected between the stand column assemblies, and the cross beams are located at the assembling gap and abut against the corresponding arc-shaped abutting blocks. According to the shield tunneling machine counter-force system, when the stand column assemblies are in a vertical state, the corresponding part of the main body structure is supported by adjusting lifting pieces, the main body structure is supported by the cross beams and the arc-shaped abutting blocks, so that counter-force is provided for the shield tunneling machine, and the problem that a hoisting device cannot be used for hoisting a counter-force frame when a structural plate above the shield tunneling machine is constructed is solved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling, in particular to a counterforce system of a shield tunneling machine and a construction method thereof. Background technique [0002] In the practice of shield tunneling, it often happens that the shield tunnel starts again after passing through a section of open-cut structure. Especially in urban rail transit and municipal engineering, shield tunneling often passes through several open-cut air shafts arranged in the interval. Or the construction situation where shield tunneling starts again after empty push through the underground station, working well and other structures constructed by other construction methods between adjacent sections. [0003] In the face of the above situation, the existing method of shield tunneling usually sets a reaction frame behind the shield machine, and assembles negative ring segments between the reaction frame and the shield machine as the reaction suppo...
