港口高填土区钻孔灌注桩施工简介

Brief Introduction to Drilling Concrete Pile at High--filling District of Port

钻孔灌注桩是直接在设计桩位上钻孔、灌注混凝土而成的桩,它具有承载力高、抗震性能好、适应大多数地质条件等优点。大连大窑湾港区雷达导航和信号台工程,就是在回填土层上钻孔灌注桩作基础,以克服回填土地基承载力小、沉降不均匀的弱点,本文对灌注桩的施工过程作了概述。

Drilling concrete pile is formed by drilling hole at design position andthen filling concrete into the hole, possessing the advantages of high bearingcapacity, good anti-seismic property and being adaptable to most geologic con-ditions, etc. In Dayaowan Radar Navigation Aid Project and Signal Stationproject, drilling concrete pile on back filling soil were used as the foun-dation so that the shortcomings such as low bearing capacity of back fillingfoundation and ununiform settlement were conquered. Construction of drillingconcrete pile is briefly introduced.
