Description

Butt joint structure for pile heads of concrete pipe piles Technical Field The invention relates to the technical field of building construction, in particular to a butt joint structure of a pile head of a concrete pipe pile. Background Concrete piles are piles made of concrete (including ordinary reinforced concrete and prestressed concrete). The composite material has the advantages of wood and steel saving, durability, low cost and the like, and is widely used for foundation engineering of hydraulic construction, industrial construction, civil construction and bridges, and is also commonly used for anti-skid or water insulation of side slopes and foundation pit supports. In the prior art, the concrete pipe piles are embedded in the pile pits, and because the pile pits are large in depth and limited in length, the phenomenon that two or more concrete pipe piles are required to be stacked in the same pile pit exists, and then the stacked concrete pipe piles are penetrated by the steel bars welded together, so that the deviation correction limit of the stacked concrete pipe piles is realized. However, when the steel bars are adopted to penetrate through the stacked concrete pipe piles, the consumption of the steel bars is large, and the construction workload of hoisting the steel bars into the reserved holes of the concrete pipe piles is large, so that the on-site construction efficiency is not improved.
