Research About Construction Technique Of Anti-Slipping Frusta In Long Tang Mountain

The coast disease site lies in a great stack of rock in Nei-Kun railway; geologic condition is very complicated. There geologic configuration is complex and condition is bad, the underground water is abundance, with stress water. There are many single stones with stiff foundation in coast body; therefore, construction is very difficult. In text, the construction technique and measure of skidproof frusta foundation frusta in piles of body are expatiated mostly, which is a part of scientific research item on Nei-Kun Line of the Railway Department General Engineering Co.The item is a construction technique research of skidproof frusta foundation frusta in LongTang mountain that is the coast disease site. In construction of skidproof frusta foundation frusta, according to different depth and geology, excavating project is modified in time, changing with geologic condition, it is successful to go through two layer of slipping surface in -11 to -25 meter, by analyzing the modificatory design project and supplement geologic reconnaissance data by Designation Department and geology circumstance and slipping distortion. It is ensured that are security and quality and the time limit for a project. The overall process of construction and putting up beam and transportation are supervised by observation station set up in coast body, the dosage of loading powder up is controlled, the speed of exploding and concussing is detected and the influence in building all round is surprised, at the same time, the breast wall of upright well is surprised in convergence security, the temperature of great body concrete of skidproof frusta foundation frusta is measured. It is validated by much data that the construction technique is scientific and reasonable and safe and dependable in skidproof frusta foundation frusta deep foundation of 3# bridge in LongTang Mountain, and that the disposal effect is all right in DK286 coast disease site.
