响洪甸水库老泄洪洞出口工作门门槽在2010年加固处理后,由于多种原因,出现沿一、二期混凝土结合面以及埋件与二混凝土接触面间渗水现象,集中后呈瀑布状从门楣上方平台溢出,影响运行环境和水库达标建设,且高压水流的渗透也可能危及门槽的结构安全。采用分批逐步加密的原则,中深孔排水降压,浅孔水泥结合化学灌浆封堵等措施,取得良好效果。
Xiang Hongdian old spillway exit gate door slot after reinforcement in 2010, due to a variety of reasons, there along the first and second phases of concrete joints and embedded parts and two concrete contact surface seepage phenomenon, concentrated after the waterfall The overflow of the platform from the top of the lintel will affect the operation environment and the construction of reservoirs, and the infiltration of high pressure water flow may also endanger the structural safety of the gate slot. Adopting the principle of step-by-step encryption, deep-hole drainage and pressure reduction, shallow hole cement combined with chemical grouting, and other measures, and achieved good results.
