Our Guilin PM section, the existing tunnels are gravel roadbed. In order to reduce the maintenance and repair of operating tunnels, improve working conditions, meet the needs of the national economic construction and the increasing development of railway transportation in our country, according to the “4 th Five-Year Plan” of our bureau, the requirements of converting the global tunnel into an integral ballast bed, Part of the manpower, select Xianggui line Porezhao No. 2 tunnel as a pilot, the method does not block lines, the construction of the tunnel as a whole bed, intended to gain experience, lay the foundation for future promotion. Bozhai 2 tunnel is 60 meters in length, all straight, flat slope, geological strength f = 3, the formation is weathered marl, the original line for the wood pillow, gravel road bed, 43 kilograms per meter rail, driving
