Concrete crack control construction method combining jump warehouse method with expansion reinforcing band

Abstract

The invention discloses a concrete crack control construction method with a jump warehouse method combined with an expansion reinforcing band. A post-cast strip of an ultra-large area basement is constructed, the jump warehouse method is adopted for achieving spaced construction, and the expansion concrete reinforcing band (9) with the concrete strength level improved by one level compared with the common concrete (11) is arranged between two adjacent bins; an expansion agent is doped into the expansion concrete reinforcing band (9). The construction method combining the jump warehouse methodwith the expansion reinforcing band avoids post-cast strip work, a large amount of working procedures of concrete post-cast strip shale chiseling, garbage cleaning, post-cast strip supporting and thelike can be reduced, the hidden danger of waterproof construction of the ultra-large area basement for control leakage can be reduced, meanwhile, basement waterproof and earthwork backfilling construction can be carried out in advance, and the structural temperature difference crack resistance is facilitated.

Description

technical field [0001] The invention relates to the field of ultra-large-area basement structure construction, in particular to a new construction method for controlling concrete cracks that combines the warehouse jumping method and the expansion reinforcement belt in the basement post-casting belt construction. technical background [0002] In recent years, with the development of society's economy and the progress of society, the basement area of ​​civil buildings has become larger and larger, and the accompanying super large basement concrete crack control technology has become more and more critical. At present, there are two measures to control concrete structure cracks: "resistance" and "release". At present, the mainstream design of the design institute is to control concrete cracks by setting post-casting strips, that is, "release". Although the shrinkage and deformation of the concrete and the settlement deformation of the building can be fully released through the ...

AI Technical Summary

Problems solved by technology

Although the shrinkage and deformation of the concrete and the settlement deformation of the building can be fully released through the "release" method, the post-casting belt is difficult to clean, which affects the quality of the post-casting belt; the chisel is not in place, and there is a risk of leakage; the overall one-time construction is difficult and costly ; The reserved time is long, affecting the overall construction progress

At present, in the construction of super-large-area basement in the prior art, the method of leaving post-cast belts is generally used to control concrete cracks. This method can fully release the shrinkage deformation of concrete and the settlement deformation of buildings, but the post-processing of post-cast belts is more difficult and costly. Leakage quality hidden dangers and other issues
