| 摘 要： | 窄口水库主坝为黏土心墙堆石坝,坝体采用0.8m厚刚性及塑性混凝土组合式防渗墙进行截渗加固,成墙最大深度为82.75 m.防渗墙造孔施工将成槽方法由二序法调整为三序法后,未再次出现连环漏浆情况,提高了防渗墙成槽期间槽孔的稳定性.超深混凝土防渗墙施工,应严格控制造孔、清孔质量,根据实际情况采取灵活的施工方法,尽可能缩短成槽周期.下设预埋灌浆管桁架或钢筋笼施工中,应避免出现桁架或钢筋笼下设不到位、导管埋深过大及浇筑过程中混凝土面上升速度不均衡问题.

| Abstract: | The main dam of Zhaikou Reservoir is a rock-fill dam with clay core.The dam strengthening adopts compound impervious wall of rigid concrete and plastic concrete of 0.8 m thickness.The maximum depth of the wall is 82.75 m.With grooving of the impervious wall made in 3 lines instead of 2 lines,interlinked leakage was controlled and slot stability in grooving was improved.In construction of impervious wall with super depth,the quality of slot cutting and clearing should be strictly controlled,and flexible meas... |
