Abstract
The invention discloses a stiff composite pile construction process. The stiff composite pile construction process comprises the following steps that S1, carrier pile construction is conducted, specifically, a, a cement-soil mixing pile with the diameter of phi 500-900 mm is adopted for a carrier pile, full pile casing follow-up impact hole forming is conducted, cement mortar or fine aggregate concrete is poured into a hole, the cement doping amount in an empty drilling area is 9%-11%, and the cement doping amount in an effective pile length area is 17%-21%; and b, carrier construction is completed; S2, a pile casing is pulled out by a carrier pile machine; and S3, a precast pile body is put down, and the pile is conveyed to the designed elevation in a static pressure or hammering mode, a, the precast pile body adopts a prestressed concrete pipe pile, the effective pile length is 42 m, and the precast pile body is constructed within 6 h after carrier construction is completed. According to the stiff composite pile construction process, construction is convenient, the secondary compaction and reinforcement effect on filling soil around a pile body is achieved, the physical and mechanical properties of a soil body around the pile are effectively improved, the stiff composite pile construction process can adapt to complex geological conditions such as deep filling soil, the construction process is different from a conventional soil compaction process, and the influence on the surrounding environment is greatly reduced.
