Dismantling process and auxiliary dismantling equipment for metro connecting channel
The invention relates to the technical field of metro construction, in particular to a metro connecting channel dismantling process and auxiliary dismantling equipment, and provides a metro connecting channel dismantling process which comprises the steps that earthwork is excavated to a base in a segmented mode, and profile steel is erected between fender posts and a bottom plate of a connecting channel; the third support is dismantled, and pouring continues to be conducted below the side wall top plate; i-shaped steel is adopted to support the fender posts at a top plate beam, and a fender post chiseling-away space is reserved; after the two fender posts are broken, the two fender posts are broken at the interval of one pile, the upper portion and the lower portion of the broken pile are cut off, and the whole cut-off pile is lifted out; and the position of a pipeline in the access portal is determined and changed, the access portal is divided into blocks to be cut, and cut fragments are removed. On the basis of the mode, the fender posts are firstly dismantled, then the access tunnel portal is dismantled, the subway connecting channel can be effectively and orderly dismantled, and the efficiency is high.
本申请涉及地铁施工技术领域，涉及地铁连接通道的拆除工艺以及辅助拆除设备，本申请提供地铁连接通道的拆除工艺，所述拆除工艺包括:分段挖掘土方至基底，在所述围护桩与所述连接通道底板间架设型钢；拆除第三道支撑，继续向侧墙顶板下浇筑；在顶板梁处采用工字刚支撑所述围护桩，预留围护桩凿除空间；破除两个所述围护桩的桩后间隔一个桩再进行破除，对破除的桩的上下进行截断，将截断后的桩整根吊出；确定所述接入口洞门中管线位置并且改移，对所述接入口洞门分块进行切割，将切割的碎块清除。基于上述方式，先拆除围护桩，再拆除接入洞门，可以有效，有序地对地铁连接通道进行拆除，效率高。
