摘要：
PROBLEM TO BE SOLVED: To provide a cut off structure using check valves for a back-fill filling hole of a soil resistant hydraulic structure such as a sealed segment, having improved working safety and workability during refilling of a back-fill material while improving the cut off performance of the check valve, allowing easy mounting/demounting thereof and improving the safety thereof, and to provide a back-fill material refilling method.
SOLUTION: On the inside back-fill material filling side (the natural ground side) of a filling pipe 2, the simple check valve 20 is provided which is normally closed and opened with the filling pressure of the back-fill material. On the back-fill material filling side (the tunnel inside), the high-water cut off check valve 10 using a compression spring 13 is easily and detachably mounted via a snap ring 14, which is normally closed and opened with the filling pressure of the back-fill material. Such double cut off improves cut off performance and safety, resulting in improved working safety and workability during refilling the back-fill material.

要解决的问题：提供一种截止结构，其使用止回阀用于诸如密封段的防污水平结构的填充填充孔，在填充填充材料时具有改善的工作安全性和可加工性 同时提高止回阀的切断性能，容易安装/拆卸，提高其安全性，并提供回填材料补充方法。 解决方案：在填充管2的内部补充填充材料填充侧（自然地面）中，设置简单的止回阀20，其通常被填充材料的填充压力封闭并打开。 在后填充材料填充侧（隧道内部）中，使用压缩弹簧13的高水分截止止回阀10经由卡环14容易且可拆卸地安装，该卡环14通常以闭合和打开的方式填充压力 背面填充材料。 这种双切割提高了切断性能和安全性，从而在再填充填充材料期间提高了工作安全性和可操作性。 版权所有（C）2009，JPO＆INPIT
