工缝漏水,采取斜缝或骑缝衬砌化学注浆(水溶性聚氨酯) 处理。施工工艺流程为:裂缝清洗钻孔清孔埋管表 面封缝通风检查浆液配置注浆封孔处理待凝检查 表面处理。 4.24.2 施工要点施工要点 4.2.1 拱部、边墙裂缝、施工缝、变形缝、环向模板拼 接缝漏水,进行裂缝堵漏和裂缝修复按如下工序进行。 (1)凿槽 凹槽长度应比裂缝每端长出 5cm 为宜。 凹槽全部采取人工手工凿得,严禁采用电动或风动工具, 以免产生震动,影响衬砌结构的稳定。在开凿前,先用墨线 弹出凿除线(以裂缝为中线,每侧各分 35cm 为开凿线) , 再用钢钎及小榔头打凿。由于工作面小,每人负责一条裂缝 的凿除,当裂缝较密时,相邻的施工人员应隔开一定距离 (不小于 1.5m)作业,以免抡锤时伤及对方。 施工时及注意以下几点: a.严格按设计图中要求的截面尺寸进行凿槽,外大内小, ndoverallleadershipresponsibilityforsafety.AdministrativeDeputyiswithinthescopeoftheirrespectiveresponsibilitiesatvariouslevelsofsecurityresponsibility,inchargeofsecurityworkinthecontextofleadership,responsibletotheChief.Fifthopenpitproductionsafetyaccidentinvestigationsystem,performedonaproductionsafetyaccidentfournoprinciple.Imposedonproductionsafetyaccidentreportstepbystepreportingthreechannels,namely,UnitChief,administrationandsafetysupervisionsystemcounterparttosuperiorleadership,reportsinatimelymanner.Sixthpitmustimplementthewhoisinchargeofwhosinchargeandhosemustbesafeprinciplesinplanning,layout,checkproductionwork,summarizedandevaluatedatthesametime,plans,features,review,summary,ratingsafetywork.Firmlyestablishingsafetyistheeffectiveness,safetyisthecredibility,safetyisthecompetitivenessawareness,tomakesafetywork.Seventhminingtradeunionorganizationaccordingtolawtheworkerstoparticipateintheworksafetyofdemocraticma

3 成八字形。 b.凹槽的深度不得小于设计深度 5cm。槽底及侧壁要平 整、规则,并用水冲洗干净。 (2)裂缝填缝料制作 衬砌表面的轻微裂缝在凿成 V 型槽后,采用环氧树脂砂 浆进行填堵。 环氧树脂砂浆是一种高快凝固,高粘度的混有砂浆的灌 浆材料。环氧砂浆配制工艺过程:环氧树脂加热至 60, 按比例加入二丁脂搅拌均匀,冷却后加入乙二胺拌匀,然后 再倒入已经混合均匀的水泥砂子中,再充分搅拌后使用。 环氧砂浆要随伴随用,其施作时间为 3040 分钟。 环氧树脂砂浆的配合比如下: 环氧树脂:丙酮:乙二胺:水泥:砂=100:15:10:150:300 水泥为 P.0425 的水泥,砂采用的是中砂。 (3)灌浆 灌浆前对灌浆机具、器具及注浆管进行检查,运行正常 后开始灌浆。将配置好的环氧树脂浆液用标尺标记,做好灌 浆记录;开始时,保持在 0.2Mpa 以上的压力,并且逐渐升 高。注意观察灌浆嘴的排气情况,待有纯浆排出,即可堵住 灌浆嘴。待最后一个灌浆嘴流出浆液时,堵住灌浆嘴,在继 续压注 5 分钟左右,关上进浆嘴上的转芯阀门,即结束灌浆。

4 灌浆结束后,立即拆除管道,并用丙酮把管道、设备清 洗干净。 施工注意事项: a.作业人员在拌制环氧水泥砂浆时应手戴胶套,防止材 料在使用时烧伤或腐蚀皮肤。 b.材料用量应严格按配合比操作,使拌制料达到最佳效 果。 c.环氧水泥砂浆的每次拌制量不宜过多,成品应尽快用 完。若在使用前已凝固,则不得使用,作废料处理。 d.为保证防水堵漏效果,膨胀型快凝水泥砂浆填塞应从 上向下做起。 e.浆液制好后,即可使用,不宜存放。 f.在填塞浆液前,将凹槽用毛刷刷干净,再刷环氧树脂 基液,而后由上而下地塞入环氧砂浆,随塞随抹,压实赶平。 每一条裂缝应一次性填塞完毕,不得中途停止而形成断节 (4) 封孔:灌浆后 2-4 天,待浆液凝结后,在用水泥浆 抹平灌浆嘴封孔。 (5)养护:在封堵完成后一周之内进行洒水养护。 4.2.34.2.3拱部、边墙点漏、群漏及拱墙交接处水平纵向施 工缝漏水有两种施工方案:斜缝钻孔注浆和骑缝钻孔注浆。 骑缝钻孔注浆施工工艺与斜缝钻孔注浆基本相同,只是注浆 孔直接接布置在缝上,而不是两侧。
