失陷性黄土地区雨水箱涵沉降加固

Settlement reinforcement of rainwater box culvert in collapsed loess area

近年来各地新区发展对雨水排放系统的要求提高,建设了许多雨水箱涵。但是在失陷性黄土地区,由于土质的特殊性,雨水箱涵基底遇水后会发生不均匀沉降,从而造成雨水箱涵的破坏或不能正常使用,需要对箱涵进行加固处理及修复。

In recent years, with the development of new areas in various regions, the requirement of rainwater drainage system has been raised, and many rainwater box culverts have been built. However, due to the particularity of soil in the collapsed loess area, the foundation of rainwater box culverts will undergo uneven settlement when it meets water, which will cause the destruction of rainwater box culverts or their normal use. The box culvert need to be strengthened and repaired.
