尖山水库塑性混凝土防渗墙采用“钻抓法”成槽,泥浆护壁,“接头管法”连接,“泥浆下直升导管法”浇筑混凝土,从施工后的蓄水情况来看,坝体已无渗漏现象,防渗指标满足设计要求,对增加稳定、减少水资源流失起到重要的作用,为尖山水库更好地发挥作用提供了可靠的保证。尖山水库塑性混凝土防渗墙施工采用“钻抓法”成槽,泥浆护壁,“接头管法”连接,“泥浆下直升导管法”的成墙施工,作为尖山水库大坝渗漏除险加固的施工方案,并取得预期效果。
Jianshan Reservoir plastic concrete cutoff wall using “drilling method ” into the groove, mud guard, “connector pipe ” connection, “under the mud pipe ” pouring concrete, from the construction of the water storage From the point of view, the dam body has no leakage phenomenon, and the seepage prevention index meets the design requirements, plays an important role in increasing stability and reducing water loss, and provides a reliable guarantee for Jianshan Reservoir to play a better role. Construction of plastic concrete cutoff wall of Jianshan Reservoir adopts the construction method of “drilling method” into a wall, mud retaining wall, “joint pipe method” connection, and “mud under the riser pipe method”. As the construction of Jianshan Reservoir Dam leakage reinforcement construction program, and achieved the desired results.
