| 摘 要： | 根据实际情况将导流建筑物分二期布置，采用全封闭围堰型式。通过对围堰不同防渗体形式的比较，选用了高喷灌浆防渗墙的方案。但由于是大粒径砂砾石围堰，高喷灌浆防渗墙施工时存在成孔困难，易蹋孔，高压喷射灌浆时易串孔，压力不易控制等困难，通过采取有效措施，高喷灌浆防渗墙施工在大粒径砂砾石围堰中取得良好效果。

| Abstract: | Considering the hydrogeologic factors in Beiyishui invert siphon project, the flow diversion structure is laid out in 2 phases and the fully enclosed cofferdam is adopted. The anti-seepage wall of high-pressure jet grouting is selected after comparing to different anti-seepage modes. There some difficulties in the construction in sand and gravel cofferdam construction of big grain-size, including hole digging, jet grouting, and pressure control. Some measurements are adopted to ensure the success of construction. |
