High-pressure-jetting cemented soil screw extrusion expansion and variable diameter concrete pile combined pile and manufacturing method thereof
The invention discloses a high-pressure-jetting cemented soil screw extrusion expansion and variable diameter concrete pile combined pile and a manufacturing method of the pile. The combined pile comprises a pile body, and the pile body is composed of a pile main body and a cement pile; a high-pressure-jetting cavity is formed between the cement pile and the pile main body, and a diameter expansion concrete body is formed by the high-pressure-jetting cavity and the pile main body through concrete pressure irrigation and arranged in the pile main body; and the combined pile is arranged in the pile body and is formed by compositing a cast-in-place concrete pile and the cement pile. The manufacturing method comprises the following steps of firstly, construction preparation, secondly, hole forming, thirdly, high-pressure-jetting grouting, fourthly, concrete pressure irrigation, and fifthly, shifting of a multifunctional drill machine, and next-step pile foundation construction. According to the high-pressure-jetting cemented soil screw extrusion expansion and variable diameter concrete pile combined pile and the manufacturing method of the pile, one-time pile forming is achieved, the construction technology is simple, operability is high, quality control is facilitated, and the pile is economical, environment-friendly, low in cost and obvious in comprehensive benefit.
