Abstract: At present the hand-dug piles and micro piles of existing features and defects, we propose a fast, safe, environmentally friendly sliding retaining structures-trenchless pile, can play similar to the hand-dug piles role. Compared with tthe hand-dug piles can be fully mechanized construction, its biggest advantage is a fast, environmental protection, conservation, safety, with significant economic and social benefits. Suitable for rock and sandstone and mudstone landslide landslide, particularly suitable for rail, road or need to quickly get through life passage disaster emergency rescue work, the application prospect.
