What is the first project of tunnel constructionNow to do some of the tunnel program, you need to be the first to list out, a total of what? I know that the first branch, two lining, inverted arch, tunnel, pavement these
The YK24 + 300 ~ YK24 + is located in the silty clay, the whole weathered rock, the strong weathered rock distribution area, the soil is soft, the rock is broken, the pore is big, the stability is bad easy to collapse. Groundwater is mainly pore water and rock fissure water, rain water is large, easy deformation collapse
YK24 + 300 ~ YK24 + + 288 as the first project of the tunnel engineering. There are many factors that affect the quality of the two lining construction, each link in the construction process must be strictly in accordance with the construction specifications
Summary of construction of the first two tunnel lining
The first project of concrete lining of this section as I bid the tunnel project, on the next two plays a role model leading lining construction, so the various factors must be considered in detail, before the construction plan, reasonable arrangement, strict control of construction process, construction timely summary, finally reached the first the United States, the project entity information is true and complete, the project finished good target
