目前,在我国建筑、冶金、电力、水利、交通、市政等部门的土建工程施工中,经常采用垂直设置的轻型井点、喷射井点、大口井、深井泵等来降低地下水位。如果采用水平设置的井点这个新工艺来代替垂直井点,不仅能有效地解决在繁华街道和建筑密集的楼群下修建地铁、隧道及厂房深基坑等工程降水的难题,而且还会大量节约井管材料,降低降水工程费用。 At present, in the construction of civil engineering projects in China’s construction, metallurgy, electric power, water conservancy, transportation, and municipal departments, vertical wells, jet wells, large wells, and deep well pumps are often used to reduce groundwater levels. If a horizontal well-setting new process is used instead of the vertical well point, it will not only effectively solve the problem of precipitation, such as the construction of subways, tunnels, and deep foundation pits under busy buildings and buildings, but also a great deal of precipitation. Save well pipe materials and reduce the cost of precipitation projects.
