王庆坨水库工程库区水井封堵效果试验研究

Experimental study on reservoir water well sealing effect in Wangqingtuo Reservoir Project

王庆坨水库是天津市南水北调中线配套工程的重要组成部分,为做好库区水井封堵工作,保证王庆坨水库库区安全,防止库区内水外渗,避免库区低水位时地下水内浸,保护水质。封井部位处理后达到库底防渗要求,本文制定了试验方案、进行了水井封堵质量标准和工艺试验标准检验,通过实地采集、分析试验数据,结果表明封井质量效果良好。

Wangqingtuo Reservoir is an important part of the supporting works in Tianjin South-to-North Water DiversionProject. The construction unit should do well in reservoir water well sealing work, guarantee reservoir safety of WangqingtuoReservoir, prevent inside and outside seepage in the reservoir, avoid underground water penetration during reservoir lowwater level, and protect water quality. Reservoir bottom anti-seepage requirements are satisfied after sealing well parttreatment. In the paper, a test plan is formulated, water well sealing quality standard and process test standard inspectionare carried out. Test data are collected and analyzed in the field. The results show that the water selling effect and qualityare sound.
