Description
Technical field
It the utility model is related to a kind of megalith mixture landslide micro combination pile group rib body barricade.
Background technology
Megalith mixture refers to the accumulation body being made up of larger-size block of stone.Due to megalith mixture by megalith accumulate and
Into, space between megalith be present, cause conventional preventing land slide method construction when larger difficulty be present, such as manually digging hole antiskid
Stake is when being applied to megalith mixture landslide control, and it is big excavation supporting difficulty to be present, and the shortcomings that big is disturbed to landslide.Therefore, need to visit
A kind of Prevention Technique for being relatively applied to megalith mixture landslide of rope.When megalith mixture landslide failure slides, the cunning at leading edge position
Body deformation is larger：Cause the block stone at its rear portion to have the space of amoeboid movement after the deformation of block stone, the motion of rear block stone can be induced
Deformation；Block stone is inlayed, is engaged again in deformation process so that megalith mixture has certain " self-stability ".Therefore, right
When this kind of landslide is prevented and treated, preferably using the prevention and controls of non-excavating construction, and emphasis adds to landslide leading edge (cutting mouth)
Gu.
At present in preventing land slide, friction pile is the most frequently used Anti-sliding stopping structure.During anti-slide pile design, using friction pile as
Bending resistance component is calculated, and determines its cross sectional dimensions, arrangement of reinforcement etc., and carry out anti-shear check.Generally use during construction
The mode of manually digging hole-making steel reinforcement cage-concrete perfusion is carried out.However, prior art has the following disadvantages：(1) excavated by manual work
Hole pore-forming difficulty is big, long in time limit；(2) there is larger potential safety hazard in underground construction in workmen；(3) during pore-forming according to
Blast working, gliding mass is disturbed larger；(4) pore-forming size is larger, easily reduces Landslide Stability during pore-forming, promotes landslide to slide.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of megalith mixture landslide micro combination pile group rib body gear
Wall, multiple rows of mini pile is squeezed into megalith mixture, using the construction method of slip casting by the hole between block stone in megalith mixture
Filled, a range of injecting cement paste and megalith mixture is formed rib body, play a part of reinforcing landslide.It is simultaneously miniature
Pile group also provides bending resistance and shear resistance, strengthens the globality and skid resistance of rib body structure, effectively improves the mechanics parameter of slide strips,
Be advantageous to the stabilization on landslide.
To solve the above problems, the utility model adopts the following technical scheme that：
A kind of megalith mixture landslide micro combination pile group rib body barricade, squeezes into multiple rows of mini pile in megalith mixture,
Mini pile be using drilling, strong arrangement of reinforcement, grouting process construct small-bore bored concrete pile, due to construct when using slip casting construction party
Method, the hole between block stone in megalith mixture can be filled so that block stone loses the space to deform, makes certain model
Injecting cement paste and megalith mixture in enclosing form rib body, play a part of reinforcing landslide.Simultaneously miniature pile group also provide bending resistance and
Shear resistance, strengthen the globality and skid resistance of rib body structure, effectively improve the mechanics parameter of slide strips, be advantageous to the steady of landslide
It is fixed.
The design principle that the utility model rib body is reinforced：
Thrust of Landslide is resisted jointly by the shearing resistance of the shearing resistance and mini pile of rib body and bedrock surface.
Utilize τ=τsAsCalculate the shearing resistance of miniature pile group；Wherein, τ is the shearing resistance per the miniature pile group of linear meter(lin.m.)；τsTo be micro-
The shearing strength of longitudinal reinforcement in type stake；AsFor the cross-sectional area of all longitudinal reinforcements in every linear meter(lin.m.) mini pile.
UtilizeCalculate the shearing resistance between rib body and bedrock surface；Wherein, τ '
For the shearing resistance between every linear meter(lin.m.) rib body and bedrock surface；γlFor the severe of rib body；AlFor every linear meter(lin.m.) rib body and the contact surface of bedrock surface
Product；α is the average angle of sliding surface at rib body；For the angle of friction between rib body and bedrock surface.
KT≤τ+τ ' need to be met
In formula, K is design safety factor (DSF)；T is per linear meter(lin.m.) Thrust of Landslide.
The beneficial effects of the utility model are：(1) megalith mixture landslide is reinforced using miniature pile group rib body, filled
The antiskid performance of megalith mixture itself is waved in distribution, reduces construction costs；(2) rig pore-forming is used when constructing, gliding mass is disturbed
Small, easy for construction, degree of safety is high；(3) speed of application is fast, can quick on-slip.
