Description
Technical field
The present invention relates to a kind of anti-slide pile structures, in particular to a kind of to be suitable for emergency rapid rescue and long-term reinforced slide
Slope, the tubular pole breast wall type packaged combination anti-slide pile structure that anti-slide performance is strong, durability is good.
Background technique
Landslide control is one, and investment is huge, technology is complicated, there are the disaster prevention and mitigation engineerings of risk for construction.China is one
The quite serious country of landslide disaster, landslide are distributed quite extensive on the ground such as the Yangtze river basin and Yunnan-Guizhou river.Public affairs are often resulted in when landslide
Road, railway, hydraulic engineering etc. destroy, and seriously threaten people's life, the safety of property.Landslide can occur in soil-slope,
It can also occur in rock side slope.For many years, it is the safety for ensuring people's lives and properties, ensures going on smoothly for economic construction,
Country consumes a large amount of human and material resources and financial resources in preventing land slide work.
Anti-slide pile controlling is begun to use to come down from the later period seventies, friction pile is made jointly by stake and surrounding ground
With Thrust of Landslide being transmitted to a kind of antiskid structure of good ground.This method be pile foundation is embedded in slider bed or gliding mass it
Under, prevent gliding mass from sliding using the tension and shearing strength and fixed section stratum drag of pile body, wherein strength of the mixing pile is by outside
The influence of factor is smaller, and is easy to be met in structure design aspect.Friction pile applies in general to shallow-layer and medium bed is sliding
Slope improvement, use flexible with position, dispersible, bricklaying is small in size, excavation face is small, destruction gliding mass is less, AsA -GSH cycle effect
It the advantages that good, is widely used in engineering practice.
With the increase of landslide control engineering scale, antiskid dowel section area and length are also increasing, material consumption quantitative change
It is very huge, the construction period is longer.Friction pile is long cantilever beam type primary structure member, mainly by suffered by sliding surface pile body below
Subgrade reaction balance Thrust of Landslide.In the case where high thrust landslide, mechanical behavior defect is more obvious, project cost
It is expensive.
In order to improve the unreasonable situation of this mechanical behavior of friction pile, reduces stake section, shorten jib-length, increase is supported
Resisting moment shortens the bore forming period, comprehensive to improve anti-slippery effect, is badly in need of the novel Anti-sliding stopping structure of research and development.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind, to squeeze into the superpower concrete tubular pile breast wall type of prestressing force small-sized
Combination anti-slid pile structure effectively adapts to quick harnessing landslide engineering, landslide emergency is robbed to increase substantially friction pile speed of application
The needs nearly administered.
The technical solution adopted by the present invention to solve the technical problems is as follows:
Of the invention squeezes into the superpower concrete tubular pile breast wall type packaged combination anti-slide pile structure of prestressing force, including interval setting
In the intracorporal monomer friction pile of cunning, pile body lower part passes through sliding surface and enters supporting course, it is characterized in that: the monomer friction pile by answering in advance
Power prestressed high-strength concrete pile, the compound composition of armored concrete inner core；The lower part of the prestressed high-strength concrete pile
Radial contraction forms pile top, and pile body is squeezed into stratum；The armored concrete inner core is poured in prestressed high strength concrete tubular
In the inner hole of stake, and consolidation is integrated therewith；The top of each monomer friction pile is with armored concrete connecting elements consolidation
One forms antiskid unit or whole framed bent formula antiskid structure.
The beneficial effects are mainly reflected as follows following aspects:
One, after tubular pole is squeezed into can first interim stabilization slopes, and provide stake holes, reinforcing bar for the armored concrete inner core in inner hole
Concrete inner core is ordinary reinforced concrete structure, effectively prevents the conventional construction method in soil property and class texture stratum and is formed
Difficulty of construction is big when stake holes, duration longer problem；
Two, ordinary reinforced concrete structure is applied in stake holes, and reinforcement is carried out to existing tube pile structure, can make monomer
Anti-slide pile structure has stronger AsA -GSH cycle, and anti-slide performance is bigger than mini pile, is suitable for the biggish landslide control of Thrust of Landslide, and
It can keep the long-term consolidation effect of slopes；
Three, driving into type tubular pole pore-forming, quick construction, the construction period is short, can be used for quick harnessing landslide, is suitable for quickly emergency
The landslide control engineering speedily carried out rescue work；
Four, it is relatively easy to squeeze into the stratum of construction, predominantly soil property or class texture stratum suitable for tubular pole, comprising: the soil body, pole
Soft rock, soft rock and highly weathered rock mass stratum.Meanwhile the landslide suitable for thickness of sliding body within 10m.
Five, during the tubular pole of with stake point squeezes into stratum with lesser stake spacing, have the function of the soil body between compaction pile, have
Conducive to raising soil strength.
