高压喷射注浆止水帷幕技术在某工程基础施工中的应用

Application of Water-stopping Curtain by High Pressure Spraying in Foundation Construction

在已有建筑群中的新建建筑物,如地下水丰富,基础施工时为保证已有建筑的安全,是不能进行大量抽水的。这种情况下,只能在基础四周采用止水帷幕措施,一是用来保证基础正常施工;二是用来防止周围地下水不发生大量流失,从而保证周围已有建筑物的安全。文章介绍高压喷射注浆止水帷幕在基础施工中的应用。

When a new building is built among a building group where the underground water is rich, heavy pumping is forbidden in the foundation construction in order to protect the exiting buildings. Under such condition, water-stopping curtain should he used on all sides of the foundation pit to make sure of the normal construction of the foundation and to prevent heavy loss of the surrounding underground water to protect the exiting buildings. This paper introduces the application of water-stopping curtain by high pressure spraying in foundation constnwtion.
