Cast-in-place pile over-filling concrete construction method
The invention provides a cast-in-place pile over-filling concrete construction method. The method includes the steps that reinforcing steel bars of a cast-in-place pile reinforcement cage over-fillingconcrete part are pretreated; reinforcement cages are hoisted in sequence, and concrete are poured to an over-pouring part to finish the pouring of the over-pouring concrete; after the concrete pouring of the over-pouring concrete part is completed, each steel bar of the over-pouring concrete part is sleeved with an isolation sleeve; after the concrete is initially set, air is introduced into theisolation sleeve; and the concrete of the over-filling concrete part is chiseled off. According to the cast-in-place pile over-filling concrete construction method, the reinforcing steel bars of theover-filling concrete part of the cast-in-place pile reinforcement cage are pretreated, after the concrete is initially set, the reinforcing steel bars of the part are sleeved with the isolation sleeve, after the concrete is initially set, air is introduced into the isolation sleeve, and finally the concrete of the over-filling concrete part is chiseled away. Therefore, the reinforcing steel barscan be effectively protected from being damaged, and meanwhile, the labor intensity of constructors is also reduced.
本发明提供了一种灌注桩超灌混凝土施工方法,包括：对灌注桩钢筋笼超灌混凝土部分的钢筋进行预处理；依次吊放钢筋笼、浇筑混凝土至超灌部位完成超灌混凝土的浇筑；待所述超灌混凝土部位的混凝土浇筑完成后，向所述超灌混凝土部分的各根钢筋上分别套设隔离套管；待混凝土初凝后向所述隔离套管内通气；凿除超灌混凝土部分的混凝土。本发明提供的灌注桩超灌混凝土施工方法，通过对灌注桩钢筋笼超灌混凝土部分的钢筋进行预处理，并在混凝土初凝后，向该部分的钢筋上套设隔离套管，待混凝土初凝后向所述隔离套管内通气，最后凿除超灌混凝土部分的混凝土，能有效保护钢筋不被损坏，同时也降低了施工人员的劳动强度。
