Abstract
The utility model relates to a prestressing force variable cross section friction pile. The friction pile is most to be the uniform section pile body, and the bending resistance ability of shearing can't be exert comprehensively in upper and lower both ends, and the material is extravagant just huge. The utility model discloses a friction pile is vertical to be constructed in the side of keeping off of gliding mass, and top -down includes cantilever section and anchor section two parts, anchor section embedded in gliding mass below stablize the stratum, the cantilever section is kept off and to be inclined stablizing gliding mass more than the stratum, cantilever section and anchor section are variable cross -section structure, and the cantilever section top -down cross sectional area scale up, and the anchor section top -down cross sectional area steadily decrease, the inboard fender face coplane of cantilever section and anchor section. The utility model discloses utilize friction pile little flexural characteristics broad in the middle, upper and lower to reduce the section size of pile body from top to bottom, effectively solved the friction pile extravagant problem of engineering of uniform section friction pile from top to bottom, the characteristics great according to the pile bolck displacement make the compression of tension side pile body at pile body stress tension side prestress application, effectively solve the great problem of pile bolck displacement.
Description
Technical field
The utility model belongs to civil works technical field, is specifically related to a kind of prestressing force variable cross-section antislide pile.
Background technology
Antislide pile is one of most important engineering measure in (side slope) harnessing project of landslide, along with railway, highway, water conservancy are towards safety, economy, environmental protection future development, the requirement of administering landslide (side slope) is also more and more higher, antislide pile is as a kind of New Retaining Structure, effect utilizes antislide pile to insert slide plane (potential water use) good ground below to carry out to the drag of stake the thrust that (anchored force) balances slide mass, increases its stability.Can be subject to the impedance of antislide pile when (side slope) body that comes down glides, after making stake, gliding mass (slope body) reaches stable state.Antislide pile bears bending and shearing under Thrust of Landslide (soil pressure) effect, and the distribution of bending and shearing on antislide pile all presents broad in the middle, little up and down loading characteristic, and displacement at pile top is larger when cantilever is longer.The antislide pile of current employing is substantially all prismatic pile body, the upper and lower two ends of antislide pile cannot play bending resistance shear resistance comprehensively, and waste of material is just huge, thus add construction investment waste, further, be difficult to when pile body cantilever segment is longer the requirement meeting specification and engineering.
Summary of the invention
The purpose of this utility model is to provide a kind of prestressing force variable cross-section antislide pile, overcomes many defects of existing uniform section pile body.
The technical scheme that the utility model adopts is:
A kind of prestressing force variable cross-section antislide pile, is characterized in that:
Described antislide pile vertically constructs the gear side in gliding mass, and comprise cantilever segment and anchoring section two parts from top to bottom, anchoring section is embedded in the good ground below gliding mass, and the gliding mass of cantilever segment more than good ground props up gear side;
Cantilever segment and anchoring section are variable section structure, and cantilever segment from top to bottom cross sectional area increases progressively, and anchoring section from top to bottom cross sectional area successively decreases, and the block face inside cantilever segment and anchoring section is coplanar.
Cantilever segment and anchoring section are integrated the single-casting of casting, and in cantilever segment and anchoring section, up/down perforation is prefabricated with prestressed reinforcement.
The variable cross-section form of cantilever segment is from top to bottom in trapezoidal, stairstepping or combination that is trapezoidal and rectangle;
The variable cross-section form of anchoring section is from bottom to top in trapezoidal, stairstepping or combination that is trapezoidal and rectangle.
The outer surface of cantilever segment offers the hole for planting Afforestation Landscape.
The utility model has the following advantages:
The utility model utilizes the sectional dimension reducing upper and lower pile body by curved feature that antislide pile is broad in the middle, little up and down, utilize the sectional dimension reducing upper and lower pile body by the feature of cutting that antislide pile is broad in the middle, little up and down, efficiently solve the engineering waste problem of the upper and lower uniform section antislide pile of antislide pile; The feature larger according to displacement at pile top, makes tension side pile compression at Stress in pile shaft tension side Shi Hanzhang, effectively solves the larger problem of displacement at pile top; At cantilever segment, structure and Afforestation Landscape being set by building side, place, effectively solving the ecological, environmental protective problem of engineering construction.The utility model avoids waste of material, expand the range of application of antislide pile, and environmental protection is attractive in appearance, has wide popularizing application prospect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1-cantilever segment, 2-anchoring section, 3-gliding mass, 4-good ground, 5-prestressed reinforcement, 6-afforests, and 7-builds place.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
A kind of prestressing force variable cross-section antislide pile that the utility model relates to, vertically construct in gliding mass 3(unstable slope body) gear side, comprise cantilever segment 1 and anchoring section 2 two parts from top to bottom, anchoring section 2 is embedded in the sliding bed of good ground 4(below gliding mass 3) in, cantilever segment 1 is in gliding mass 3 the gear side of good ground more than 4, the anchored force provided by anchoring section 2 resists the slide downward of gliding mass 3 by cantilever segment 1, at Stress in pile shaft tension side Shi Hanzhang.Pile body opposite side is for building place 7.
Cantilever segment 1 and anchoring section 2 are variable section structure, decrease excavated volume and material usage, cantilever segment 1 from top to bottom cross sectional area increases progressively, anchoring section 2 from top to bottom cross sectional area successively decreases, a block face inside cantilever segment 1 and anchoring section 2 is coplanar, form the variable section structure form thick in the middle of whole pile body, two ends are thin, can effectively play by curved, subtracted ability.The variable cross-section form of cantilever segment 1 is from top to bottom in trapezoidal, stairstepping or combination that is trapezoidal and rectangle; The variable cross-section form of anchoring section 2 is from bottom to top in trapezoidal, stairstepping or combination that is trapezoidal and rectangle.
Cantilever segment 1 and anchoring section 2 are integrated the single-casting of casting, and in cantilever segment 1 and anchoring section 2, up/down perforation is prefabricated with prestressed reinforcement 5(steel strand).Cantilever segment 1 and anchoring section 2 stress tension side adopt prestressed reinforcement 5 Shi Hanzhang to make tension side pile compression, can effectively reduce the lateral displacement at cantilever segment 1 top, meet engineering demand.
The outer surface of cantilever segment 1 offers the hole for planting Afforestation Landscape, not only attractive in appearance but also can save material, also can play the effect of draining.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model manual to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
