Pneumatic down-the-hole hammer vibration jet grouting pile inserted steel pipe composite foundation and pile foundation construction method
The invention discloses a pneumatic down-the-hole hammer vibration jet grouting pile inserted steel pipe composite foundation and a pile foundation construction method. The construction method comprises the steps that drilling is conducted; after drilling to the designed depth, a water pump of the drilling machine is switched into a high-pressure pump to pump cement paste, the high-pressure paste is subjected to high-pressure air jet grouting, vibrated and lifted, and the jet grouting pile is formed; a steel pipe is inserted into the center of the pile to form a stiffened core cement soil steel pipe pile; and the steps are repeated, a plurality of stiffening core cement soil steel pipe piles are constructed at intervals according to the design, and a composite foundation or a steel pipe pile foundation is formed. The method has the advantages that the application range is wide, the construction speed is high, the bearing capacity and settlement deformation requirements can be met, and the comprehensive cost is low.
一种风动潜孔锤振动旋喷桩插钢管复合地基或钢管桩基的施工方法，包括步骤：钻孔；形成旋喷桩：钻孔到设计深度后，将钻机的水泵切换为高压泵泵送水泥浆，高压浆高压风旋喷振动上提，形成旋喷桩；在桩中心位置插入钢管，形成劲芯水泥土钢管桩；重复上述步骤，按照设计间隔施工出多根所述的劲芯水泥土钢管桩，形成复合地基或钢管桩基。本发明的优点是：适用范围广，施工速度快，能保证承载力及沉降变形要求，综合成本低。
