Problems solved by technology
Hammering type and static pressure type refer to the construction methods that use physical methods to drive or press prefabricated piles into the ground. During the pressing process, it is easy to damage the prefabricated piles, resulting in a decline in their performance; Concrete piles are poured in the ground, but the quality of cast-in-place concrete piles is not easy to control, and the pile quality is unstable

The invention discloses a foundation pile construction method. The foundation pile construction method comprises the following steps: step I, preparing a precast pile for standby application, whereinthe precast pile comprises a tubular pile body and a connecting block provided with a plurality of through holes, and connecting holes are formed in the side wall of the top of the pile body. step II,cleaning the ground to be constructed and performing tamping; step III, determining and marking the position of a foundation pile needing to be constructed on the tamped ground; step IV, digging a pile hole in the marked position of the construction foundation pile p, leveling the bottom of the pile hole, and breaking up foundation materials taken out during pile hole digging for standby application; step V, placing the pile body in the pile hole, besides, adding a curing agent and a binding agent into the foundation materials taken out during pile hole digging, performing uniform mixing to obtain mixed foundation materials, rapidly adding the mixed foundation materials into gaps of the pile hole and the hollow position in the pile body, and tamping the newly-added mixed foundation materials in the pile hole; and step VI, inserting connecting blocks into the pile body, and inserting reinforcing steel bars into the matched connecting holes and penetrating holes in a penetrating manner.The method is high in practicability, and the pile forming structure is stable.
Description
technical field [0001] The invention relates to the technical field of building construction. More specifically, the present invention relates to a foundation pile construction method. Background technique [0002] The foundation pile construction method refers to the single pile construction method in the pile foundation construction process. At present, there are three main foundation pile construction methods: hammering type, static pressure type and embedded type. Hammering type and static pressure type refer to the construction methods that use physical methods to drive or press prefabricated piles into the ground. During the pressing process, it is easy to damage the prefabricated piles, resulting in a decline in their performance; Concrete piles are poured in the ground, but the quality of the cast-in-place concrete piles is not easy to control, and the quality of the piles is unstable. Contents of the invention [0003] It is an object of the present invention to...
