扬巴污水提升泵站压密注浆施工组织设计方案

扬巴污水提升泵站压密注浆施工组织设计方案污水提升泵站压密注浆施工方案污水提升泵站压密注浆施工方案一、一、前言前言Preface污水提升泵站压密注浆主要针对其基坑底板下部的约1.8m厚的粉土，因其底板呈阶梯部，部份土体滑动，造成部份底板与其下部粉土的分离，而形成空洞，目前通过现场勘察，因破坏处为16×3×1.8m。因而要求采用注浆方式进行土体加固。Thisplanismainlyaimedatabout1.8mTHKpowdersoilinthebottomslaboffoundationpit.Asthebottomslabisinastepandpartofthesoilisslided,someslabsareseparatedfromthepowdersoil.Sothehollowsturnup.Afterthesiteinvestigation,asthebrokenareais16*3*1.8m,methodofgroutingshouldbeadoptedforthesoilstrengthening.二、二、压密注浆方法压密注浆方法MethodologyforCompactionandGrouting该工程基坑底板现已浇注成功，依据现场的破坏程度及以往的施工经验，先通过人工方式在底板开孔，然后依据水灰比0.5~0.6的方案进行搅拌水泥浆，再将搅拌均匀的水泥浆用机械方式输入孔洞中，已达到加固地基土为目的。Thebottomslabinfoundationpithasbeensuccessfullyplaced.Accordingtothedamagedegreeandourconstructionexperience,firstlywewillmakeholebymanpower,secondlymixcementmortarinawatercementratioof0.5~0.6.Thencementmortarwillbeconveyedintoholesbymachinetomeettherequirement.三、三、施工淮备施工淮备ConstructionPreparation1、设置制浆站、加浆站尽量减少移动次数。Establishthemortarprocessstationandaddingstationtominimizethetim
