Abstract
The utility model discloses a retaining structure of delta-shaped double-row antiskid piles. The retaining structure comprises a front row of antiskid piles and a rear row of antiskid piles, wherein the pile-distributing plane of double rows of piles is of a delta shape; and a herringbone truss reinforced concrete truss connecting beam is arranged on the top parts of the piles. The retaining structure has the advantages that the double rows of antiskid piles are fixedly embedded in a stable rock-soil body, and are distributed in the delta-shaped manner; and the herringbone truss connecting beam is arranged at ends of a cantilever to bear a horizontal thrust, so that the action of the bending moment is reduced, further the horizontal displacement is better controlled, the capability for bearing the landslide thrust force can be greater improved, and more economic and reasonable effects are achieved. The retaining structure has the advantages that the stressing and deformation states of cantilever piles are improved, the problem that the single row of piles can not resist the excessive landslide thrust force is effectively solved, and the problem of an included angle between the direction of the landslide thrust force and the slope surfaces of suspended side slopes also can be effectively solved. The retaining structure is especially applicable to large-scale landslide treatment works and high-slope shoring engineering.
Description
Technical field
The utility model relates to a kind of anti-sliding support structure, specifically is used for the larger landslide control engineering and the anti-sliding support structure of high slope support engineering.
Background technology
High slope supporting and landslide control are the great difficult problems of engineering circle always; Often dig up mine, repair the roads, bridge construction and the mountain area building side's of cutting leveling, all possibly run into complicated stratum, and produce a large amount of height according to the needs of engineering and cut slope and artificial earth fill's side slope; Make original topography and geomorphology that very about-face take place; Broken own balance originally, the slip that will produce certain scale causes very big threat for the people's life and property.Therefore, it is necessary to carry out reliable anti-sliding support.
For larger landslide control engineering and high slope support engineering, we often adopt antislide pile, anchor cable, antislide pile+anchor, antislide pile+measures such as support.Single antislide pile and many row's antislide piles can be administered fairly large landslide, arrange the gradable opposing Thrust of Landslide of antislide pile more, stressed indeterminate, the shortcoming that cost is higher of stake before and after having.The measure of antislide pile+support is comparatively economical, and its shortcoming is that support should be positioned at stable stratum, and when (potential) slide plane was dark, support often was difficult to construction.Anchor cable is a kind of scheme of economy, but its difficulty of construction is very big, is difficult for pore-forming at bad ground, and construction quality is difficult to control, and because the stress relaxation effect often makes that its long-term consolidation effect is difficult to guarantee.The anchoring stratum of anchor cable receives more restriction in addition.
Summary of the invention
The utility model provides a kind of anti-sliding support structure, can solve the problem that above-mentioned prior art exists effectively.
The utility model is Chinese character pin-shaped double antislide pile retaining structure, comprises front-seat antislide pile and back row's antislide pile, and the double-row pile layout that lays out pile is Chinese character pin-shaped, and the stake top is provided with chevron shaped truss reinforced concrete truss and connects beam,
The two ends that described chevron shaped truss reinforced concrete truss connects beam are arranged on the stake top of front and rear row friction pile; Perhaps an end pushes up in stake, and the other end is in the stake bottom.
Chinese character pin-shaped double antislide pile retaining structure is achieved in that
⑴ earlier the front-seat antislide pile of construction and back row's antislide pile, the Chinese character pin-shaped layout in stake position;
⑵ front-seat antislide pile embeds stable rock-soil layer with back row's antislide pile, promptly in the good ground below (potential) slide plane;
⑶ cut the stake top laitance of front-seat antislide pile and back row's antislide pile, high until design stake top mark;
⑷ front-seat antislide pile all is provided with steel reinforced concrete fore shaft beam with row's antislide pile stake top, back, and the front and back campshed is provided with chevron shaped reinforced concrete coupling beams between the top, forms chevron shaped truss and connects beam;
⑸ chevron shaped truss connects beam can imbed below ground.
The beneficial effect of the utility model has following: double antislide pile all is mounted in the stable geotechnical body; Make full use of the Chinese character pin-shaped layout in stake position; At cantilever end chevron shaped truss is set and connects the joist support horizontal sliding power of carrying water, reduce the moment of flexure effect, its objective is controlling level displacement better; The ability of bearing Thrust of Landslide obtains bigger raising, and more economical rationality.This retaining structure has improved the stressed and deformation state of cantilever pile, has solved single stake effectively and can't resist the excessive problem of Thrust of Landslide, can also effectively solve Thrust of Landslide direction and the angle problem of facing the sky side slope surface.Technology is simple, and space multistory reasonable structural arrangement and stable acting charitably are specially adapted to larger landslide control engineering and high slope support engineering.
