《河南水利与南水北调》2022年第12期百家谭嵩湖堤除险加固工程射水造墙孔壁稳定问题探讨黄鑫(江西省水利水电开发有限公司,江西南昌330029)摘要:抚州市临川区嵩湖乡辖区嵩湖堤除险加固工程射水造墙施工过程中主要面临造孔孔壁稳定的技术难题。在简述工程概况的基础上,从造孔过程控制、射流口紊流控制、泥浆固壁及地下水位影响等方面对孔壁稳定控制问题进行了分析探讨。结果表明,射水造墙主要由造孔技术和水下混凝土浇筑技术两部分组成,其中孔壁稳定是成孔的关键。通过加强造孔施工参数控制,提升不同施工阶段泥浆性能,根据地下水位控制泥浆密度等措施的应用,以取得较为理想的射水造墙加固施工效果。关键词:除险加固;射水造墙;孔壁;稳定中图分类号:TV543文献标识码:A文章编号:1673-8853(2022)12-0106-03DiscussionontheStabilityofWaterJettingHoleWallinSonghuDikeReinforcementProjectHuangXin(JiangxiWaterResourcesandHydropowerDevelopmentCO.LTD.,Nanchang330029,China)Abstract:IntheconstructionprocessofwaterjettingwallinSonghuDikeReinforcementProjectinSonghuTownship,LinchuanDistrict,FuzhouCity,themaintechnicalproblemsofholewallstabilityareencountered.Onthebasisofsummarizingthegeneralsituationoftheproject,theproblemsofholewallstabilitycontrolareanalyzedanddiscussedfromtheaspectsofholemakingprocesscontrol,jetinletturbulencecontrol,mudwallconsolidationandtheinfluenceofgroundwaterlevel.Theresultsshowthatthewaterjettingwallismainlycomposedoftwopartsoftheholemakingtechnologyandtheunderwaterconcretepouringtechnology,inwhichthestabilityoftheholewallstabilityisthekeytotheholeforming.Bystrengtheningthecontrolofconstructionparameters,improvingthemudperformanceindifferentconstructionstages,andcontrollingthemuddensityaccordingtotheundergroundwaterlevel,theidealconstructioneffectofwaterjettingwallreinforcementcanbeachieved.Keywords:dangereliminationandreinforcement;waterjettingwallbuilding;holewall;stability1工程概况嵩湖堤除险加固工程坐落于抚州市临川区嵩湖乡辖区,位于抚河中游左岸及梦港河下游右岸,整个防护圈长度13.53km,圩堤总长12.23km。其中0+000~5+800堤段位于抚河中游左岸,7+100~13+530堤段位于梦港河下游右岸,两段堤中间5+800...
