Background technique
In recent years, while rapid development with infrastructure construction, also there is a large amount of landslide disaster problem, with regard to cloud
South inside the province for, annual big and small landslide accident just reaches up to a hundred, and small-sized landslide accounting is larger, thus caused by indirectly
Economic loss is inestimable.
Mini pile is less than 300mm as a kind of diameter, pile body generallys use steel pipe, reinforcing bar or fashioned iron, is filled in a manner of mud jacking
The elongated pile body of pea gravel concreten or cement mortar is filled out, can not only be constructed under complicated landform, it is especially narrow in discrepancy difficulty, place
There is advantage more outstanding under narrow equal execution conditions.It is small that strengthening stratum disturbance is treated in miniature pile construction, the reachable ground of reinforcing scope
Lower water level is hereinafter, work progress mainly can guarantee construction personnel in landslide or potential landslide location in ground progress well
Safety.Pile body speed of application is fast, in emergency work, can fast and effeciently play the role of reinforcing dangerous soil layer.For this purpose,
For handling small-sized landslide, mini pile at engineers first choice.
Traditional miniature steel pipe pile is as a kind of elongated pile body, and bending resistance is often inferior to shear resistance, for slip mass
Compared with thick one, the gliding mass thrust arm of force is larger, and torque is also larger, is often easier to reach the Ultimate Bearing Capacity of mini pile.Together
When, mini pile diameter of steel tube is smaller, and rigidity is also smaller, and slight curves deformation may cause stake top and generate biggish position at sliding surface
It moves.
Summary of the invention
The purpose of the utility model is to provide a kind of composite structure mini piles for administering small-sized landslide.The mini pile is not
The rigidity of mini pile only can be improved, the tensile property of steel and the compressive property of concrete can also be given full play to, greatly mentioned
The anti-bending bearing capacity and ductility of high mini pile.
The technical solution of the utility model includes: a kind of composite structure mini pile for administering small-sized landslide, includes tee bar, T
The web end of shape fashioned iron is connected with seamless steel pipe, has poured pea gravel concreten in seamless steel pipe, and the mini pile is put into when use
In drilling and its top extend out to earth surface of side slope face, and the stake top that mini pile stretches out earth surface of side slope face is partly embedded into earth's surface linking beam
In.
The composite structure mini pile above-mentioned for administering small-sized landslide, mini pile are put between pile body and hole wall in drilling and infuse
Enter pea gravel concreten or cement slurry forms stake week reinforcing body.
The composite structure mini pile above-mentioned for administering small-sized landslide, the foot of hole are located at the following basement rock in slope sliding face
Or in anchoring body.
The composite structure mini pile above-mentioned for administering small-sized landslide, the earth's surface linking beam by earth's surface linking beam indulge muscle and
Earth's surface, which links beam stirrup and is banded after-pouring concrete, to be formed.
The utility model has the beneficial effects that compared with prior art, T shape in the mini pile of the composite structure of the utility model
The flange plate of fashioned iron mainly provides tensile stress, this is exactly the advantage of steel, while being filled in seamless steel pipe pipe by pea gravel concreten,
Pea gravel concreten provides compression, and under the constraint of steel pipe, pea gravel concreten is in three dimension stress state, just plays thin
The advantage of stone concrete, and in the top of mini pile embedment earth's surface linking beam, can be improved globality between mini pile with cooperate with
Property, make to form an entirety between composite structure mini pile, anti-slippery effect enhancing.The mini pile of the structure not only can be improved miniature
The rigidity of stake, can also give full play to the tensile property of steel and the compressive property of concrete, greatly improve the anti-of mini pile
Curved bearing capacity and ductile performance.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model
The foundation of limitation.
The embodiments of the present invention: a kind of composite structure mini pile for administering small-sized landslide, as shown in attached drawing 1-4, packet
Tee bar is included, 2 end face of web of tee bar is connect by the way of butt welding with 4 outside tube wall of seamless steel pipe, and seamless steel pipe 4 is managed
Inherent factory pours into pea gravel concreten 3 by grouting pipe, is transported to construction site after pea gravel concreten 3 reaches design strength, will
Its embedment has been applied in the drilling 10 being drilled, and the miniature stake top of composite structure stretches out 9 certain length of earth surface of side slope face, is connected with earth's surface
Binder 5 connects, to improve the globality and concertedness between mini pile.Composite structure mini pile be factory complete at
Product, so that the better quality of composite structure mini pile, site operation speed is faster.Composite structure mini pile is resisting side slope
When 8 or more rock mass of sliding surface glides, the flange plate 1 of tee bar mainly provides tensile stress, this is exactly the advantage of steel, while nothing
Seam steel pipe 4 is filled in managing by pea gravel concreten 3, and pea gravel concreten 3 provides compression, and under the constraint of steel pipe, microlith coagulation
Soil 3 is in three dimension stress state, just plays the advantage of pea gravel concreten 3.
The miniature stake top of composite structure is stretched out ground table segment and is connect with the steel reinforcement cage in earth's surface linking beam 5, and steel reinforcement cage is by earth's surface
Linking beam indulges muscle 6 and earth's surface links the binding of beam stirrup 7 and formed, and casting concrete forms earth's surface linking beam after steel reinforcement cage places
5, it can make to form an entirety between composite structure mini pile, anti-slippery effect enhancing.
Pea gravel concreten 3 is injected between the pile body and hole wall that composite structure mini pile is put into drilling 10 or cement slurry is formed
The all reinforcing bodies of stake, improve the integral strength of composite structure mini pile.
10 bottoms of the drilling are located in 8 or less basement rock of slope sliding face or anchoring body.When there is small-sized landslide, side slope
The soil and sandstone of 8 or more sliding surface can slide, and the basement rock of its bottom or anchoring body will not slide, composite structure
Basement rock or anchoring body are stretched at the top of mini pile to be slided together with topsoil or sandstone, to play very well
Antiskid performance.
It when the composite structure miniature pile construction, carries out by the following method: first in factory by seamless steel pipe 4 and tee bar
Web 2 weld combination, pour into pea gravel concreten 3 inside seamless steel pipe 4, conserve, the prefabricated composite structure conserved is micro-
Type stake is transported to construction site；Secondly easily landslide slopes carry out drilling 10 operations, drilling 10 it is essential apply get into slope sliding face 8 with
Certain distance in lower basement rock or anchoring body checks drilling after the completion of drilling 10, lifts mini pile smoothly after qualified
It is put into drilling 10, borehole wall is not touched during being put into, miniature stake top, which should control, is being higher by earth surface of side slope face 9 centainly
Distance, while pea gravel concreten 3 or cement grout formation stake week reinforcing body are poured into conduit in mini pile stake week hole；To same
After arranging miniature pile construction, by by earth's surface linking beam indulge muscle 6 and earth's surface link the steel reinforcement cage that beam stirrup 7 is formed be placed on it is miniature
At stake top, pouring for earth's surface linking beam 5 is then carried out, so that in miniature stake top certain length embedment earth's surface linking beam 5, shape
At an integer support system.
