Construction method for preventing pier wall concrete temperature cracks

The invention discloses a construction method for preventing pier wall concrete temperature cracks, which belongs to the technical field of building construction, according to the invention, the ductile super-retarding fine aggregate concrete with the initial setting time of 48-72 hours is used for pouring concrete at the root part of a pier wall; constraint conditions between a bottom plate and the pier wall can be improved, constraint of the bottom plate on temperature deformation of the pier wall is reduced, temperature stress of the pier wall is reduced, risks of cracks of the pier wall can be reduced, and the common construction defects that a joint surface of the pier wall and the bottom plate is prone to root rotting and the like in conventional construction can be overcome. 一种防止墩墙混凝土温度裂缝的施工方法，属于建筑施工技术领域，本发明将初凝时间为48h～72h延性超缓凝细石混凝土用于墩墙根部混凝土浇筑，本发明可改善底板与墩墙之间的约束条件，减轻底板对墩墙温度变形的约束，降低墩墙温度应力，可以减少墩墙裂缝产生风险，还能解决墩墙与底板结合面常规施工易产生烂根等施工缺陷通病。
