摘要 关键词：桩施工管理 ABSTRACT In the bored pile construction, due to lax control, improper operation, geological condition difference to wait for a variety of reasons, is easy to cause construction quality defects.On the basis of perfusion pile construction experience, detailed description of the cast-in-place pile construction technology and quality control points, is proposed and analyzed in pouring pile construction quality problems and reasons, according to the concrete problems in study and formulate the corresponding measures, on the current stage of filling pile of common quality problems in construction and prevention treatment is of practical significance.Pile foundation is a kind of relatively mature foundation treatment methods in civil engineering has a wide range of applications. This paper refers to himself in South Asia of 1 site practice during the access to information, the project site is located in the Wuchang District of Wuhan City Road to the East, Wenxiu street to the north, geomorphic unit belonging to the two Yangtze River terraces, site of relatively flat terrain.Through the practice during the period of observation and study, from which I found some problems, and to think.This paper mainly in the bored pile construction scheme for clues, describes the process and method of construction, elaborated the pouring pile common problem types, causes and treatment measures, including the drilling process of construction quality problems and treatment measures, concrete pouring process of construction quality problems and treatment measures, perfusion into after the pile quality defects found and treatment. Key words: pile Construction technology Quality problems Construction management Treatment measures 目录 摘 要 1 ABSTRACT 2 目录 3 第一章 前言 1 第二章 桩基础概述 2 第一节 常见桩的类型 2 第二节 灌注桩的特征和适用条件 2 第三节 预制桩的特征和适用条件 3 第三章 工程概况及工程地质条件 5 第一节 工程概况 5 第二节 地质条件 5 第四章 钻孔灌注桩施工方案 6 第一节 工艺流程 6 第二节 施工方法 7 第五章 灌注桩常见问题的类型、成因及处理措施 11 第一
