Background technology
At present, using more ripe in (side slope) harnessing project of landslide is exactly common excavation type friction pile, the tension higher compared with high pressure resistance energy and armored concrete of concrete in bending deformation and shear behavior is it makes use of as heavy in section excavation type friction pile, skid resistance can be well provided when it arranges harnessing landslide with a determining deviation, limit development and the downslide on landslide.The advantage of common excavation type friction pile: (1) is applied widely；(2) anti-sliding support ability is strong；(3) construction is simple.Shortcoming has: (1) mechanized construction degree is poor；(2) hand excavation's danger is high；(3) market prospect of hand excavation is poor；(4) big to rock side slope undisturbed soil disturbance.
Also having a kind of retaining structure conventional in landslide antiskid is speedily carried out rescue work is the miniature pile group of type, utilizes mini pile to provide shear resistance to provide certain skid resistance, stops landslide to glide deformation.The advantage of miniature pile group: (1) speed of application is fast；(2) mechanization degree is high, it is to avoid excavated by manual work stake.Shortcoming: (1) is poor for applicability in incompact-deposit bodies landslide (side slope)；(2) the transmission poor performance of stake soil compatible deformation and power；(3) anti-bending strength is poor；(4) during rainfall, inter-pile soil is easy to run off, perishable muscle material, causes potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of churning friction pile, to solve stake soil compatible deformation and the transmission poor performance of power that existing miniature pile group exists；Anti-bending strength is poor；During rainfall, inter-pile soil is easy to run off, perishable muscle material, the problem causing potential safety hazard.
This utility model be the technical scheme is that a kind of churning friction pile, it is made up of rotary churning pile, muscle material, top cap, rotary churning pile is many, the center of every rotary churning pile is inserted with muscle material, the stake top of every rotary churning pile is connected into an entirety by top cap, rotary churning pile at parallel main sliding direction partly overlaps layout, leaves space between the adjacent rotary churning pile of vertical main sliding direction.
Preferably, rotary churning pile passes through gliding mass, sliding surface and stretches in slider bed.
Preferably, rotary churning pile stretch into that the length of slider bed is long not less than rotary churning pile stake 1/2.
Preferably, at the overlapped a length of 0.3m-0.4m of rotary churning pile of parallel main sliding direction.
Preferably, the spaced width of rotary churning pile at vertical main sliding direction is 0.3m-0.5m.
Preferably, a diameter of 0.6m-1.0m of rotary churning pile.
Preferably, top cap is reinforced concrete structure, and top cap is arranged at above-ground route top.
Preferably, the rotary churning pile outermost spacing that the length of top cap is arranged not less than parallel main sliding direction, the rotary churning pile outermost spacing that the width of top cap is arranged not less than vertical main sliding direction, the height of top cap is not less than 1m.
Preferably, muscle material stretches into the length of top cap not less than 0.3m.
This utility model is according to matrix arrangement by some rotary churning piles, and rotary churning pile leaves space between main sliding direction close arrangement, vertical main sliding direction stake, and muscle material is inserted at every rotary churning pile center, and stake top uses top cap to connect into an entirety, can preferably power be handed on.Hole between vertical main sliding direction stake can effectively draining, be beneficial to stablizing of slope body, stake top forms top cap with big thickness concrete again and is rigidly connected each mini pile, ultimately form fix with top cap, the stake soil miniature pile group of type integrally.The existence of big thickness concrete top cap makes each micro-pile combined effect, after inter-pile soil churning simultaneously, the raising of intensity makes mini pile and soil between pile deformation hight coordinate, the transmission of power is smooth and easy, there is while ensureing its energy shearing resistance the performance of stretch bending component, bending resistance increases, and is effectively improved its anti-slide performance.This utility model is that middle-size and small-size landslide (side slope) provides a kind of flexible simple, short construction period of constructing, is applicable to the Miniature anti-slide pile group structure of the bigger soil property of plasticity.
The beneficial effects of the utility model are: rotary spray technique is introduced in landslide (side slope) harnessing project by (1)；(2) speed of application is fast；(3) it is prone to structural defence；(4) flexible arrangement is various.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
As it is shown in figure 1, Y-direction is main sliding direction in figure.
A kind of churning friction pile, it is made up of rotary churning pile 2, muscle material 8, top cap 1, and rotary churning pile 2 is many, shows 12 in Fig. 1.The center of every rotary churning pile 2 is inserted with muscle material 8, and the stake top of every rotary churning pile 2 is connected into an entirety by top cap 1, and the rotary churning pile 2 at parallel main sliding direction partly overlaps layout, leaves space between the adjacent rotary churning pile 2 of vertical main sliding direction.
