Study On The Key Technologies Of Construction Techniques For Embankment Of Double-Tracking Railway In Soft Soil Region

With the China's ailway project launched one after another at the same time, double-track construction is also progressing steadily. In this paper, a double-track railway in soft soil subgrade construction research of key technologies for the direction of the project in the common soft ground treatment, alternative materials selection, water damage prevention and roadbed construction programs carried out some useful exploration, combined with engineering to determine the actual situation work out a specific implementation plans. Made in soft ground treatment of soft base under the cushion thickness choice for filling method, riprap agent overwhelmed France and playing Vibro CFG pile method of construction. The roadbed construction scheme selection, in accordance with the principles of choice of roadbed construction plan, combined with the characteristics of this project, choose a more feasible subgrade construction programs. During the construction process in time and space management, combined with the existing lane to the number and the actual situation in the project, through comparative analysis, choose a rectangular skylight in the night, set up the construction methods. In the analysis of domestic and international packing and problems of classification, based on the proposed changes to the program classification embankment filling, combined with practical engineering and experimental analysis of data, choose to use the mechanism to replace river sand mountain sand. With engineering in the embankment, cutting the construction of water damage problem, a common embankment, cutting the construction of water damage prevention and control measures.
