Construction method for punching cast-in-place pile
The invention provides a construction method for a punching cast-in-place pile. The construction method comprises the following steps of a measuring step, specifically, leveling a to-be-constructed site, measuring and setting out, and determining the position of a pile hole; a drilling step, specifically, burying a steel casing at the position of the pile hole, and drilling; a treatment step, specifically, after drilling to penetrate through the top of a karst cave, treating the karst cave according to the parameters of the karst cave, drilling to penetrate through the treated karst cave, and continuously drilling to the pile bottom position of the pile hole; a hoisting step, specifically, cleaning the pile hole, and hoisting a reinforcement cage into the pile hole; and a pouring step, specifically, cleaning the pile hole again, and pouring underwater concrete into the pile hole. According to the construction method, when the karst caves are encountered in the construction process of the punching and filling pile, the karst caves are treated according to the parameters of the karst caves, drilling is conducted after the karst caves are treated, the reinforcement cage is hung in the pile hole, and underwater concrete is poured, so that the pile forming quality can be guaranteed, the over-filling amount of the concrete can be reduced, the throwing and filling project amount is reduced, the project cost is saved, and the method is wide in applicability and high in pertinence.
本发明提供了一种冲孔灌注桩施工方法，该方法包括如下步骤：测量步骤，平整待施工场地，测量放线并确定桩孔的位置；钻孔步骤，在桩孔的位置处埋设钢护筒，并进行钻孔；处理步骤，钻孔穿设溶洞的洞顶后，根据溶洞的参数对溶洞进行处理，并钻孔穿设处理后的溶洞，继续钻进直至桩孔的桩底位置；吊放步骤，对桩孔进行清理，并向桩孔内吊放钢筋笼；灌注步骤，对桩孔再次清理，并向桩孔内灌注水下混凝土。本发明中，冲孔灌注桩施工中遇到溶洞时，根据溶洞的参数对溶洞进行分别处理，在处理溶洞后再钻孔，在桩孔内吊放钢筋笼并灌注水下混凝土，不仅能保证成桩质量，还能减少混凝土的超灌量，减少抛填工程量，节约工程造价，该方法适用性广、针对性强。
