Construction method for breaking and removing monolithic track bed in subway operation line tunnel
The invention discloses a construction method for breaking and removing a monolithic 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, temporary steel sleeper transition line is installed, passage is recovered; 3, third-stage concrete breaking and removing is conducted. According to the construction method, 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, 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.
