Long spiral drilling pressure grouting pile construction pile casing and construction process
The invention discloses a long spiral drilling pressure grouting pile construction pile casing and a construction process. The long spiral drilling pressure grouting pile construction pile casing comprises a wing ring and a pile body which are integrally arranged, wherein a plurality of hanging ring holes are uniformly distributed in the wing ring, and the outer diameter of the pile body is matched with a pile hole; the wing ring and the pile body are both made of rubber materials, and a plurality of models are arranged according to the different outer diameters of the pile body; and the innerparts of the wing ring and the pile body are both of hollow structures, and a plurality of rubber supporting ribs are uniformly distributed in the wing ring and the pile body correspondingly. According to the long spiral drilling pressure grouting pile construction pile casing and the construction process, the buffering effect of the pile casing is utilized, the vibration amplitude of an upper steel reinforcement cage can be reduced in the vibration lowering process of the steel reinforcement cage, and then the phenomenon of segregation of concrete due to excessive vibration is reduced; and the pile casing is used for fixing the upper position of the steel reinforcement cage in the lowering process of the steel reinforcement cage, so that the perpendicularity of the steel reinforcement cage is guaranteed.
本发明公开了一种长螺旋钻孔压灌桩施工护筒及施工工艺，包括：一体设置的翼环和筒身，翼环上均布于若干个吊环孔，筒身的外径与桩孔相匹配。翼环和筒身均为橡胶材质，且根据筒身的外径不同设置有若干个型号。翼环和筒身的内部均为中空结构，翼环和筒身的内部分别均布有若干个橡胶的支撑筋。本发明利用护筒的缓冲作用，在钢筋笼振动下放过程中，可以减缓上部钢筋笼的振动幅度，进而减轻混凝土因过震而发生离析的现象；利用护筒在钢筋笼下放过程中固定钢筋笼上部位置，保证钢筋笼垂直度。
