毕业设计[论文]题目：桥梁钻孔灌注桩施工工艺及质量控制学院：交通运输工程学院专业：**************姓名：***学号：*******指导老师：王连军完成时间：2014年5月18日河南城建学院本科毕业设计（论文）摘要I摘要灌注桩是指在工程现场通过机械钻孔、钢管挤土或人力挖掘等手段在地基土中形成桩孔，并在其内放置钢筋笼、灌注混凝土而做成的桩，依照成孔方法的不同，灌注桩可分为沉管灌注桩、钻孔灌注桩和挖孔灌注桩等几类。而钻孔灌注桩是按成桩方法分类而定义的一种桩型。随着我国交通事业的全面发展，桥梁钻孔灌注桩工艺及应用也发生了日新月异的变化。本文以江特特大桥为例，浅谈了钻孔灌注桩施工工艺及质量控制，系统的阐述了钻孔桩具有施工方便、操作简便、设备投入小的特点,介绍了钻孔灌注桩的施工工艺及其注意要点,指出在施工前应做好各项准备工作,以保证工程质量及其进度。关键词：灌注桩，施工工艺，质量控制河南城建学院本科毕业设计（论文）AbstractIIAbstractFillingpileinengineeringfiledbymeansofmechanicaldrilling，steeltubesoilcompactionorhumanminingmethodsformedinfoundationsoilpilehole，andplacedinsidereforcingcage，perfusionpile，madeofconcreteandinaccordancewithdifferentmethodsandpilesintoholesandcanbedividedintodrivencast-in-placepiles，boredpilesanddig-holepilesetccategories.Accordingtothecast-in-placepileintopilesofclassificationanddefineakindofpiletype.Withtheall-rounddevelopmentofourcountry'stransportbusiness,bridgeboredpilestechnologyandapplicationalsohaschangedwitheachpassingday.Injianglubridgeasanexample,thispaperdiscusstheboredpilesconstructiontechnologyandqualitycontrol,systemelaboratedthedrilledpilehastheconstructionisconvenient,easytooperate,thecharacteristicsoftheinvestmentofequipment,thispaperintroducestheconstructiontechnologyofboredpilesanditsattentionpoints,pointsoutthatshoulddowellinthepreparationworkbeforeconstruction,toensuretheengineeringqualityandprogress.Keywords:boredpiles，Theconstructiontechnology，Controlthequality河南城建学院本科毕业设计（论文）目录目录1、引言...................................................................................................................12、工程概况............................................................................................................22.1桥址概况.............................................................................................................22.2工程地质条件.....................................................................................................22.3水文地质特征.....................................................................................................32.4桥址地震动参数.................................................................................................32.5桥址气象条件.....................................................................................................32.6桩基设计情况.....................................................................................................32.7混凝土拌合系统.................................................................................................52.8施工用水、电布置.............................................................................................52.8.1施工用水...................................................................................................52.8.2施工用电...................................................................................................52.9施工道路布置.....................................................................................................62.10施工场地布置...................................................................................................63、施工总体方案....................................................................................................73.1总体方案.............................................................................................................73.2施工进度计划.....................................................................................................73.3资源配置.............................................................................................................73.3.1机械配置....................................................................................................73.3.2施工人员配置............................................................................................84、钻孔桩施工工艺流程.........................................................................................95、施工方法..........................................................................................................105.1施工准备............................................................................................................105.1.1场地平整.................................................................................................105.1.2桩位测量放样.........................................................................................105.1.3埋设护筒.................................................................................................115.1.4钻机就位.................................................................................................115.1.5泥浆池布置及泥浆制备.........................................................................115.2钻孔...................................................................................................................125.2.1开孔及成孔方法.....................................................................................125.2.2成孔检查.................................................................................................125.3第一次清孔.......................................................................................................135.4钢筋笼加工及吊放.........................
