简述高地下水位降水技术

Brief Description of the Technology of Water Level Precipitation in the Highlands

人工降低地下水,常用的方法有轻型井点、喷射井点、电渗井点、管井井点等。电渗井点主要在淤泥和淤泥黏土中使用;喷射井点降水深度大,但造价高昂;轻型井点设备简单,安装快捷,是目前降水施工中常用的方法,但降水半径小;管井井点降水深度大,影响半径大,造价较低,常与其他方法综合利用。

The common methods of artificial groundwater reduction are light wellp oint,jet well point,,and tube well point,etc.The electric well point is mainly used in silt and silt clay; The jet well point precipitation depth is large, but it is expensive; Light well point equipment is simple and quick to install, which is a common method in precipitation construction, but the precipitation radius is small;The well point precipitation depth is large, the influence radius is large, it costs little and it is often used synthetically with other methods.
