Abstract
Mushuang hydrologic water base under the surface of 5. 5 m, foundation pit depth of 5. 84 m, foundation construction flow sand and water problems, forcing backfill has excavation of foundation pit construction units, modify the construction schemes, finally used the method of large diameter well construction, namely, large diameter artificial dig-hole pile construction method. Open well method construction process and the matters needing attention are introduced, compared with the original design of the construction scheme, construction method of large diameter well with safe and reliable, low cost, cover an area of an area small, etc. When water station construction design, the foundation construction possible landslides, flow sand, water, suggest design construction scheme of using the method of large diameter well construction.关键词
