大体积混凝土池体裂缝处理

Mass Concrete Pool Body Fracture Treatment

通过对裂缝成因、危害进行分析,提出合理的治理方案即:裂缝处理首先采用环氧树脂压力灌注,对裂缝的结构进行补强;采用聚氨酯压力灌注,对裂缝的渗漏修补。通过在安哥拉污水厂1,2号奥贝尔氧化沟裂缝处理中的实际应用取得了良好效果,为以后类似池体裂纹的处理总结了经验,同时对于在非洲炎热地区施工大型池体、大体积混凝土裂纹防止也提供了借鉴经验。

In this paper, the causes of cracks, hazards analysis, proposed a reasonable treatment program that： the first crack treatment using epoxy resin pressure perfusion, the structure of the crack reinforcement; use of polyurethane pressure perfusion, the leakage repair cracks. Through the practical application of the oxidation of Auerbel oxidation ditch No. 1 and No. 2 in Angolan Sewage Treatment Plant, good results have been obtained, and the experience lbr the similar treatment of pool cracks is summed up. At the same time, lbr the construction of large-scale pool body in the hot area of Africa, The volume concrete crack prevention also provides a reference experience.
