钻孔灌注桩的施工质量控制.rar

钻孔灌注桩在城市建筑和桥梁工程中得到普遍应用。但由于其施工工艺的特殊性和复杂性，施工的全过程质量控制就显得十分重要。笔者针对钻孔灌注桩施工过程中常见的问题，阐述正循环钻孔灌注桩施工过程中质量控制要点。
一、施工准备
1、钻孔灌注桩施工方案的审核
①根据设计图纸、地质报告、现行规范标准以及现场勘查结果，审查施工方案的编制依据、施工工艺流程、技术指标、安全措施等内容是否符合要求。针对混凝土初灌量的计算可参照JTJ041-2000(公路工程标准)的规定进行复算。同时还应审查施工方案中处置突发事件的应急预案是否符合要求。对于施工方案的审核应具有前瞻性，要善于提出问题、发现问
Bored in the city and bridge construction projects are universally applied. However, the construction process due to its particularity and complexity of the whole process of construction quality control is very important. I bored the construction process for common problems, described being bored during the construction cycle of Quality Control.
First, construction preparation
1, bored pile construction plan review
① According to design drawings, geological reports, the current specification standards, and site inspection results, review the basis for the preparation of construction programs, construction process, technical specifications, safety, etc are to meet the requirements. The amount of concrete filling for the beginning of the calculation can refer JTJ041-2000 (road engineering standards) the provisions of recalculation. Should also review the construction program to emergencies contingency plan is to meet the requirements. Construction program for the audit should be forward-looking, should be good to ask questions, find Q
