Construction method for changing monolithic track bed to floating slab track bed in subway operation line tunnel
The invention discloses a construction method for changing a monolithic track bed to a floating slab track bed in a subway operation line tunnel. The construction method comprises the following steps that 1, first-stage concrete breaking and removing is conducted; 2, second-stage concrete breaking and removing is conducted, a temporary steel sleeper transition line is installed, and passage is recovered; 3, third-stage concrete breaking and removing is conducted; 4, foundation concrete construction is conducted; 5, steel bars are tied, and new foundation rapid hardening concrete is poured; 6, floating slabs are laid. A laid track bed is cut through low-noise rope saws and wall saws, cut laid slabs are lifted and conveyed through researched cantilever cranes in a subway tunnel, the new floating slabs are laid, and then the laid monolithic track bed is changed. By the adoption of the construction method, noise is low, the operation line does not stop during construction, safety and reliability are achieved, and the requirements for urban civil construction, operation line transportation, operation line safety and construction efficiency are met.
