Description
Technical field
The present invention relates to landslide control engineering, in particular to the anti-skid system of a kind of big ability and construction method.
Background technique
Landslide structure is generally made of the slip band of top gliding mass and lower part slider bed and centre, between landslide and slider bed
Interface is known as sliding surface, and the crushed zone near sliding surface is known as slip band.In landslide engineering, mainly since slip band is by rainwater
Lower infiltration or influence on groundwater, the Thrust for the gliding mass that never can resist after mechanical index reduction, cause the phenomenon that comes down.Traditional landslide
Control measures are to arrange that 3~5 row's large size friction piles resist Thrust of Landslide on slip mass, since friction pile needs manually digging hole ten
Several meters of even tens of meters of depths, in some high altitudes and cold areas such as Sichuan-Tibet construction of railways, manual work is difficult and security risk compared with
Height, execution conditions are very poor, and traditional engineering measure urgently improves.
Current pertinent literature shows that domestic and international project personnel have conducted extensive research antiskid structure, but generally all also
It is angularly to be changed from structure stress, rigidity, cost and change functionally are little.
For example, a kind of friction pile arching combination is disclosed in the patent of invention specification of patent No. ZL201110318602.8
Structure and construction method, the composite structure include the friction pile that the tunnel two sides Jian Shen are arranged in a manner of flush type, and friction pile
Stable basement rock is protruded into, arching is connect with two sides friction pile, and the earthwork of tunnel arch is provided with the work space with two sides antiskid stake body
The connected shield arch of steel, protects on arch backfill rock layers after having stake.Suitable under ditch heart shape, earthing is thin on tunnel, two sides
The pre- supporting and retaining system reinforcing construction of tunnel portal when slope stability is poor or poor integrally combines friction pile and arching, shield arch
Mode, substantially increases the stress performance of friction pile, and ditch heart tunnel portal two sides side slope and upper overburden layer is made to form whole add
Gu reducing excavation and the reinforcing of ditch heart two sides side slope, it ensure that the stabilization and ecology of original slopes, saved two sides side slope
Reinforcement cost.
Prestressing force rubble uranium anchor and its landslide are disclosed in patent No. ZL201510038431.1 patent of invention specification
Administer construction method, rubble anchorage pile is column structure, including anchor head disk, rubble integrate draining section, chassis, blotter, porous
Floral tube and several prestressed anchors.Porous floral tube, which runs through, to be arranged between anchor head disk and rubble integrate draining section, and anchor is stretched out at top
Plane in cephalic disc, prestressed anchor passes through rubble integrate draining section and both ends are individually fixed on anchor head disk and chassis, sets on chassis
There is tapping pipe, rubble integrate draining section is connected by tapping pipe with blotter.The structure can effectively reduce ground water water in slip mass
Position reduces slip mass interior moisture content, the shear behavior of sliding surface is also added, to improve the stability on landslide.
In patent No. ZL201611028972.7 patent of invention specification, a kind of townhouse hollow section composite structure is disclosed
Antiskid pile group and its construction method, antiskid pile group are combined by multiple isolated friction piles and a series of binding-beams, friction pile
Centre be equipped with hollow structure, binding-beam includes a crossbeam, and there is a vertical beam at the both ends of crossbeam, and crossbeam and vertical beam are integrally formed, connection
The vertical beam of knot beam one end can closely form structure compatible with hollow structure, friction pile with the vertical beam of the neighboring bracing beams other end
It is inserted into hollow structure jointly by the vertical beam of binding-beam one end and the vertical beam of the neighboring bracing beams other end, by isolated friction pile
Form antiskid pile group.The structure is simple, safety, construction technology strong operability, can effectively reduce landslide control engineering investment.
Foregoing invention patent adjusts structure application process by improving in construction in pilework or integrating by composite structure
In force modes, improve structure entirety anti-slide performance.But friction pile still uses the branch gear pattern fully against sliding force, needs
More than ten meters of manually digging hole even tens of meters of depths, concrete amount is big.The high and cold high altitude localities such as line in Sichuan-Tibet, high gradient slope construction
Condition is excessively poor, by geology and weather conditionality, such as uses above-mentioned antiskid structure, then can be tired in face of cast-in-place concrete maintenance
It is difficult, manual operation amount is big, project cost is high and manually across hole workload is big and unsafe problem.
