地基基础分部工程验收技术分析

地基基础分部工程验收技术分析摘要文中研究了地基基础分部工程验收技术等问题。对于工程实体的检查主要还是要看设计图纸对地基与基础的设计形式了，若地基处理采用的是换填法（砂垫层），那么重点应检查换填范围、分层施工的垫层密实度等。若为成孔灌注桩，则需要重点检查：成孔和清孔的方法和质量：钢筋笼制安质量、安装深度：水下混凝土浇灌方法、充盈系数：开挖后桩位偏差、孔深、桩体质量、砼强度、桩身承载力、垂直度等。对于回填土则需要重点检查回填土土质、表面平整度、分层厚度及含水量、夯实系数、回填标高控制等。关键词：地基：重点检查：质量Technical analysis of engineering acceptance offoundation divisionAbstractIn this paper,the acceptance technology of foundation division engineering and other issuesare studied.The inspection of the engineering entity mainly depends on the design form of thefoundation and foundation in the design drawings,if the foundation treatment adopts thereplacement method (sand cushion),then the focus should be on checking the scope ofreplacement,the compactness of the cushion of layered construction,etc.If it is a hole-formingpile,it is necessary to focus on checking:the method and quality of hole forming and holecleaning;Rebar cage safety quality,installation depth;underwater concrete pouring method,filling coefficient;After excavation,pile position deviation,hole depth,pile body mass,concretestrength,pile bearing capacity,verticality,etc.For backfill soil,it is necessary to focus onchecking the backfill soil quality,surface flatness,layered thickness and water content,compaction coefficient,backfill elevation control,etc.Keywords:Foundation;Focus on checks;quality目录商要.044000Abstract..............第一章地基与基础分部工程施工验收标准1.1喷锚支护验收标准。1.1.1喷锚支护设计.。1.1.2设计说明1.1.3特殊情况处理1.2人工挖孔扩底桩施工验收标准.21.2.1施工要点.21.2.2质量要求.21.3钢筋工程验收标准.31.3.1钢筋的进场与验收.31.3.2钢筋的加工和堆放31.3.3钢筋的连接与锚固.41.3.4钢筋绑扎1.4模板工程验收标准。.51.4.1模板选型设计.51.4.2梁、墙、平台模板.51.4.3电梯井模板.…..61.4.4剪刀墙支模.…。.61.4.5梁柱结合部模板...61.4.6楼梯间模板.61.4.7模板拼缝处理….71.4.8模板的拆除与维修…7第二章地基基础工程质量检查要点..82.1检查内容.…..82.1.1现场质保体系检查.….82.1.2设计文件、施工方案检查…8
