Long spiral drilling pile construction method
The invention discloses a long spiral drilling pile construction method which comprises the following steps that a plurality of reserved holes with the diameter being the same as that of a reinforcement cage are drilled in the outer side of the pile foundation range, and the reinforcement cage is placed in the reserved holes; putting a vibration device into the reinforcement cage and connecting the vibration device with the reinforcement cage; hoisting a vibration device and a reinforcement cage and driving the vibration device and the reinforcement cage into concrete in the pile foundation; the reinforcement cage is vertically placed in the preformed hole, then the vibration device is lowered into the reinforcement cage, then the reinforcement cage and the vibration hammer are lifted together through a crane, and the problems that in the previous construction process, due to the fact that the reinforcement cage is horizontally placed on the ground, the damage risk of positioning ribs of the reinforcement cage exists, and in the lifting process, the vibration hammer is damaged are solved. The phenomenon that the reinforcement cage is broken due to the fact that welding spots of the reinforcement cage are prone to falling off and reinforcing hoops are prone to being damaged when the reinforcement cage is straightened only by means of a vibratory hammer is avoided.
本发明公开了一种长螺旋钻孔桩施工方法，包括以下步骤：在桩基范围外侧打设若干直径与钢筋笼直径相同的预留孔，并将钢筋笼放置在所述预留孔内；将振动装置下方至钢筋笼内并与所述钢筋笼连接；吊装振动装置和钢筋笼并打设入桩基中的混凝土内；本发明采用将钢筋笼竖直放置在预留孔内，然后将振动装置下放至钢筋笼内，完成后再使用起重机将钢筋笼与振动锤一起起吊，避免以往的施工过程中，钢筋笼水平放置于地上，存在钢筋笼定位筋损坏风险，且在起吊过程中，仅仅凭借振动锤对钢筋笼进行调直，钢筋笼焊点极易发生脱落，加强箍易发生损坏，导致钢筋笼发生折断的现象。
