Abstract

The invention provides a static crushing structure for removing concrete and a construction method thereof. The static crushing structure comprises a concrete structure and a steel bar structure poured into the concrete structure. The static crushing structure further comprises an embedded pipe set embedded in the concrete structure, wherein the embedded pipe set is composed of a plurality of embedded pipes, and the pipe orifices of the embedded pipes are exposed out of the concrete structure. Since the embedded pipes are embedded in the concrete structure, when the concrete structure is removed, a worker just needs to pour an expanding agent into the embedded pipes and then add water into the embedded pipes, and then the interiors of the embedded pipes can be made to expand rapidly. Under the effect of the expanding static force, the concrete structure can be stripped from the steel bar structure slowly, and thus the problems that in the prior art, the number of static crushing procedures is large, and the cost is high are solved.
