Description
Technical field
The utility model belongs to field of civil engineering, specifically a kind of anchor cable framed bent Antiskid pile combination retaining structure.
Background technology
The area of China's mountain and hill accounts for 2/3 of territory total area, geological disaster takes place frequently, and wherein one of maximum geological disaster is endangered on landslide, and the direct economic loss that landslide is caused is very serious, especially in the southwest of China, the many and A wide selection of colours and designs of geological disaster quantity.Wherein accumulation body is one of factor causing the shallow-layer geological disasters such as avalanche, landslide, mud-rock flow.Accumulation body is in critical condition usually, and one meets excavation, rainfall, explosion or earthquake, very easily ftractures, disintegrates or comes down, bring harm to personal security and engineering construction.Along with the development of China's economic society, increasing engineering must relate to the Geological Hazard come down as main, reliable in order to ensure engineering safety, and supporting construction must be adopted to carry out Reinforcement.Common supporting construction type is more, as gravity retaining wall, balance weight retaining wall, off-load plate type retaining wall, cantilever retaining wall, counterfort retaining wall, reinforced earth retaining wall, soil nail wall, antislide pile, stake plate type retaining wall, platy structure, prestress anchorage cable etc., for antislide pile, anchor cable, existing retaining structure harnessing landslide mode will be analyzed below.
Antislide pile be a kind of by its anchoring section side direction subgrade reaction to resist cantilever segment soil pressure or landslide sliding force laterally bearing pile.The stabilization of antislide pile to sliding mass is the thrust that the drag (anchored force) utilizing antislide pile to go deep into the following good ground generation of slide plane balances sliding mass, increases its stability.Be subject to the drag of antislide pile when sliding mass glides, make gliding mass reach stable state.For shallow-layer and medium-bedded landslide, antislide pile has significant superiority, and normally reliable to the treatment effect on landslide.But for thick-layer and giant heavy laver land slide, because sliding mass thickness is large, antislide pile freedom length is longer, and the moment that Thrust of Landslide produces is excessive.For the effect of opposing Thrust of Landslide, require that the cross-sectional area of antislide pile is comparatively large, improve the difficulty of construction of antislide pile, add the cost of engineering, and also not necessarily reliable to the impedance effect on landslide.
Prestress anchorage cable makes accumulation body reach stable state by applying stretching force to anchor cable to reinforce Rock And Soil or improve the retaining structure of internal stress situation.Anchor cable is a kind of component mainly bearing pulling force, is fixed in the good ground of deep by boring and injecting cement paste by steel strand, on the surface being reinforced body, steel strand is carried out to the stress of stretch-draw generation, thus reaches and make to be reinforced body and stablize the object with restrained deformation.Its main feature to utilize Rock And Soil self-strength and self-bearing ability, greatly alleviates dead load, and saving engineering material, is efficient, economic reinforcing technique.
In sum, when harnessing landslide, antislide pile has significant superiority when processing shallow-layer and medium-bedded landslide.Anchor cable can be reinforced Rock And Soil and change its internal stress state, and regulation effect is reliable, remarkable in economical benefits.
