| Abstract: | 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. |
