PHC tubular pile planting construction method

Abstract

The invention relates to a PHC tubular pile planting construction method. The PHC tubular pile planting construction method comprises the following steps that a pile casing is provided, and the pile casing is screwed into a soil body according to the preset position and the preset elevation of a PHC tubular pile; the soil body in the pile casing is dug out; a protective material is poured into the pile casing to enable the height of the poured protective material to be lower than that of the pile casing; the PHC tubular pile is provided, and the PHC tubular pile is hoisted into the pile casing to enable the PHC tubular pile to reach a preset elevation of the PHC tubular pile; and concrete is poured into the PHC tubular pile to the top of the PHC tubular pile, and therefore pile planting of the PHC tubular pile is completed. As the PHC tubular pile is continuously immersed into the protective material, the holding and wrapping effect of the protective material on the PHC tubular pile is also continuously enhanced, the PHC tubular pile can be prevented from deviating in the horizontal direction under the holding and wrapping effect of the protective material, the PHC tubular pile can only gradually sink in the protective material in the vertical direction under the self-weight effect of the PHC tubular pile, and therefore the pile planting effect of the PHC tubular pile can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction method for planting PHC pipe piles. Background technique [0002] With the rapid development of my country's national power and economy, PHC pipe pile foundation has been widely used in such areas for its characteristics of "standardized production of component factories, high degree of integration of on-site resources, low cost per unit bearing capacity, and suitable for construction on sandy or clay soils". widely used. [0003] At present, there are two main construction methods for PHC pipe piles in China: static pressure and hammering. In the static pressure method and hammering method, in the process of soil subsidence, PHC pipe piles are prone to deflection or broken piles under the resistance of the soil or the force of hammering, which affects the pipe piles. pile quality. Contents of the invention [0004] The purpose of the present invention is ...
