Construction method of super-high-rise core tube wall concrete structure
The invention relates to a construction method of a super-high-rise core tube wall concrete structure. The construction method comprises the following steps: carrying out layered construction on a core tube wall from bottom to top; scattering stone in formworks of a lower-layer structure of the core tube wall when the lower-layer structure of the core tube wall is constructed and concrete is poured to a position which is distant from a set elevation by a set distance; vibrating the outsides of the formworks of the lower-layer structure of the core barrel wall so as to enable the stones to sink; forming an irregular connecting surface on a concrete pouring surface by the stones after final set of the poured concrete and constructing an upper-layer structure of the core barrel wall on the connecting surface; and repeating in such a way until construction of the core barrel wall structure is finished. The stones are scattered on the pouring surface of the lower-layer structure of the core barrel wall, the outsides of the formworks are vibrated to enable the stones to sink properly, the problem that manual laitance chiseling is difficult to control is solved effectively, and construction time is short.
