Foundation treatment pile and pile splicing method thereof

Abstract

The invention discloses a foundation treatment pile and a pile splicing method thereof. The foundation treatment pile comprises a pile body formed by sequentially connecting precast single piles, a connecting head is arranged at one end of each precast single pile, each connecting head comprises a rod body axially arranged and an expansion head at the external end of the rod body, and the diameter of the expansion head is larger than that of the rod body; an end plate is fixed at the other end of each precast single pile, connecting holes matched with the connecting heads are formed in the end plates, the connecting holes comprise communicated rib inserting holes and rib sliding holes adopting long-strip-shaped structures, the diameters of the rib inserting holes are larger than the diameters of the expansion heads, and the widths of the rib sliding holes are larger than the diameters of the rod bodies and smaller than the diameters of the expansion heads; by adopting the mechanical connection way that the connecting heads are matched with the connecting holes, on-site quick pile splicing is achieved, and the foundation treatment pile provided by the invention has the advantages that the structure is simple, the construction efficiency is high, the cost is low, and the load bearing capability of the pile is strong.

Description

technical field [0001] The invention relates to the technical field of foundation treatment, in particular to a foundation treatment pile and a pile connection method thereof. Background technique [0002] Ground treatment is an artificial ground treatment method adopted in weak ground and special ground in order to increase the bearing capacity of the ground and improve its deformation or permeability properties. [0003] At present, the commonly used artificial foundation treatment methods include soil replacement cushion method, heavy hammer surface compaction, dynamic compaction, vibrating, sand pile compaction, deep mixing, surcharge preloading, chemical reinforcement and other methods. The disadvantage of these methods is that all the processes are carried out on the construction site, the construction efficiency is low, and it is greatly affected by environmental factors; Difficult to guarantee, affecting the safety of the superstructure. [0004] The use of factory...

AI Technical Summary

Problems solved by technology

At present, during foundation treatment, prefabricated piles are mainly connected by welding, which is greatly affected by the weather, and the welding quality is difficult to guarantee; the welding cooling time is long, which affects the efficiency of pile connection; at the same time, the arc light generated by electric welding poses occupational hazards to operators
