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。 4.2 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，

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。 灌浆结束后，立即拆除管道，并用丙酮把管道、设备清洗

4 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
