摘要
S313线兰嘎段LJ-11标位于内蒙古南部毛乌素沙漠腹地,地层为粉细砂。为完成涵洞基坑开挖任务,经方案比选采取轻型井点降水措施。主要介绍轻型井点降水的施工设计、井点管安设、降水、施工注意事项等内容,并分析了影响降水的各种因素,提出了改进降水效果的有效途径和措施,对类似工程有借鉴意义。
The LJ Contracted Section of the Langa Section of the S313 Line is located in the hinterland of the Maowusu Desert in the southern part of Inner Mongolia,the stratum of which is fine sand.For the foundation pit of the culvert to be successfully excavated,the light-well point precipitation measures are taken through the comparison and choice of the various schemes.The construction design of the light-well point precipitation,the laying of the well-point pipes,precipitation and points for attention in the construction are introduced,with various precipitation-affecting factors and measures for improving the effects of precipitation analyzed.The project may serve as a useful reference for other similar ones.
