Water conservancy and hydropower engineering gate slot second-stage concrete dismantling construction structure

The utility model discloses a second-stage concrete dismantling construction structure for a gate slot in water conservancy and hydropower engineering. The second-stage concrete dismantling construction structure comprises a plurality of rows of horizontal drill holes, vertical drill holes, a rope sawing machine and a carrier. The device is simple in structure and reasonable in design, the to-be-dismantled concrete area is divided into a plurality of to-be-dismantled concrete sections by arranging a plurality of rows of horizontal drill holes in the to-be-dismantled concrete area, and each to-be-dismantled concrete section is divided into a plurality of to-be-dismantled concrete blocks by arranging a plurality of vertical drill holes. The multiple to-be-dismantled concrete blocks are dismantled one by one through the rope sawing machine, the dismantled to-be-dismantled concrete blocks are carried to the ground through the crane when each to-be-dismantled concrete block is dismantled, actual construction is ea
