Description
Technical field
Preventing land slide technical field is the utility model is related to, more particularly to a kind of Combined Anti-sliding supporting.
Background technology
It is harm of the preventing and treating landslide on building and influence, it is necessary to necessary engineering measure be set in landslide front portion, with resistance
Only it is slided.In China, the development of Anti-slide engineering mainly experienced following several stages：
(1) before the 1960s, retaining engineering uses antiskid retaining wall and minor diameter more in preventing land slide both at home and abroad
Friction pile.There is significant limitation in this technical measures, particularly big to Thrust of Landslide, sliding surface is deeper in actual applications
Major landslip, long and short anchor arm and small bore friction pile are then helpless, and excavate retaining wall foundation suitable danger be present
Property, quantity of masonry is big, and construction costs is high.
(2) after the 1960s, applicant with other Railway Design departments Chengdu-Kunming railway construction in, joint research
Heavy in section borehole reinforced concrete pile, and it is successful on the husky northern 1# landslides of Chengdu-Kunming railway and Ganluo station 2# landslides first Application.But
Similarly there is the problem of foregoing in this heavy in section stake holes of being excavated before slip mass, produce stake deformation in practice and excessively topple over mistake
The example of effect is quite a few.
(3) the aforementioned structure popularization and application in railway subgrade works quickly after the seventies, and constantly improve is innovated, and is successively gone out
" ∏ " the shaped steel frame row of piles set by the iron forth academy in branch willow line sieve according to small stream landslide and Chengdu Railway Bureau are showed in nineteen eighty-three in river
" h " type framed bent friction pile used at the line K180 embankment slides of Guizhou Province.
Friction pile has been developed as a kind of ripe landslide control engineering measure at present, and its main antiskid principle is：
The soil arching effect formed by means of the frictional resistance of antiskid section below pile body sliding surface and the stake back of the body soil body and stake both sides is slided with stable
Body, its mechanism of action are to be passed to down the Thrust of Landslide of lack of equilibrium in gliding mass by friction pile using the stake being embedded in slider bed
In the stable Rock And Soil in portion, so as to stabilization and slopes are balanced, reach the purpose of harnessing landslide.Common friction pile has quantity of masonry
Small, construction safety is reliable, flexible arrangement facility, the advantages that strong adaptability.
But with the increase of Thrust of Landslide, need effectively to disperse away these internal force to reduce Internal forces.
Utility model content
The purpose of this utility model is to provide a kind of Combined Anti-sliding supporting, and it can effectively disperse the thrust on landslide, enhancing
The structural strength of antiskid supporting.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of Combined Anti-sliding supporting, including soil nailing, coupling beam and the steel-pipe pile for being inserted in landslide layer and stabilized zone, the soil
Nail one end is inserted in the other end in stabilized zone and is connected with the steel-pipe pile upper end, and the coupling beam is connected on horizontally adjacent steel-pipe pile
End.
By using above-mentioned technical proposal, the setting of soil nailing is drawn to the upper end of steel-pipe pile, can share steel-pipe pile by
The part Thrust of Landslide arrived.And coupling beam connects horizontally adjacent steel-pipe pile, then the part power that steel-pipe pile is subject to is passed to adjacent
Steel-pipe pile, so as to when local steel-pipe pile stress is excessive the adjacent less steel-pipe pile of stress can share certain power.
Further, the angle of the soil nailing and the steel-pipe pile is in 45-60 °.
By using above-mentioned technical proposal, 45-60 ° of angle can increase horizontal component of the soil nailing to steel-pipe pile pulling force.
Further, two soil nailings are connected with the steel-pipe pile, the angle between the soil nailing is in 10-20 °.
By using above-mentioned technical proposal, the setting of two soil nailings can share what half was subject to relative to a soil nailing respectively
Power, improve the resistance to plucking of soil nailing.Two soil nailings can provide bigger pulling force in the case where not damaging for steel-pipe pile.
Further, the steel-pipe pile is in hollow structure, and cement block is filled with the steel-pipe pile.
By using above-mentioned technical proposal, cost can be reduced in the case where ensureing structural strength.
Further, the soil nailing includes Ribbed Bar and the cement layer being wrapped in outside soil nailing.
By using above-mentioned technical proposal, cement layer is after Ribbed Bar inserts stabilized zone, is formed along Ribbed Bar
Hole pour, cement layer mixes with soil, stabilized zone, can increase the withdrawal resistance of soil nailing.
Further, the coupling beam is C60 concrete blocks.
By using above-mentioned technical proposal, the coupling beam made of C60 concrete, for the concrete block of high intensity, can improve
The resistance to plucking of coupling beam.
In summary, the utility model has the advantages that：The setting of soil nailing is drawn to the upper end of steel-pipe pile,
The part Thrust of Landslide that steel-pipe pile is subject to can be shared, and coupling beam connects horizontally adjacent steel-pipe pile, the then portion being subject to steel-pipe pile
Component passes to adjacent steel-pipe pile, so as to which when local steel-pipe pile stress is excessive, the adjacent less steel-pipe pile of stress can share one
Fixed power.
