Abstract

Punching pile is a commonly used construction technology for pile foundation of river-crossing bridges, which has the advantages of small impact on the sur-rounding environment, strong adaptability of pile length and pile diameter, the pile end can enter the holding layer or be embedded in the rock layer, and large bearing capacity of a single pile, etc. However, the process and operation requirements are more strict and prone to quality accidents. However, the hole formation process and operation requirements are more stringent, and quality accidents are prone to occur. Based on the pile foundation project of Shenzhen Changchun North Road Bridge, this paper analyzes the quality control requirements of large diameter bored piles in land and water construction, proposes the pile foundation application process under adverse geological conditions, and at the same time, also proposes the measures to prevent and deal with quality problems. Through these measures, the 36 bored piles (24 piles of 1.5m diameter and 12 piles of 1.6m diameter) of this bridge are all class I piles after testing, with good quality control effect, which can provide relevant engineering experience for the subsequent municipal bridges across the river with similar structures.
