土钉墙与锚拉桩(Soil-nailed wall and anchor pile) Answer yesterday the earth old hat 20 asks!! What is the concept of composital only as a load of soil as a combination of body: The supporting work is in synchronous with the excavation of the foundation pit, which is constructed from top to bottom, and the overall progress is fast and the construction period is not occupied. It occupies a small space, but it can be applied to complex environment geology conditions. It is easy, simple, reliable and reliable, but not high cost. Compared with traditional support structure, it is only 50 ~ 70. Therefore, it has wide application prospect. For more than a decade, China has experimented with many projects, and the effective soil nailing system is composed of soil nails, reinforced soil and surface structures. The mechanism of soil nailing wall stress in soil nailing wall system, the stress of the soil nail is an important component, the function of soil nail can be divided into the water and soil pressure acting on the surface or cement-soil pile, through soil nail and soil friction is passed to the stability of the strata, similar to the soil anchor. The deformation of the soil under the wall is restrained by the dense and short soil studs, forming a composite soil composed of soil, grouting and soil nails, and the composite soil is similar to the force of gravity dam. The effect is simil
