The structure on landslide.
Background technology
Landslide is a kind of common multiple natural calamity, it can cause dike, highway and railway roadbed and
Industry, civil buildings are wrecked, and heavy losses are brought to national economy.The conventional method for administering soil body landslide is to build gear
Cob wall or embedded friction pile, anchored pile.Both because it is respective the defects of and be limited in a particular application.
Friction pile is the main branch blocking means currently used for administering the larger landslide of thrust, multiple rows of anti-by being set in gliding mass
Sliding pile, classification resistance Thrust of Landslide, to reach the purpose of harnessing landslide, but the measure is used for landslide control and there is stress to fail to understand
Really, the defects of big is invested；Anchored pile can provide the retaining structure of larger drag, and its principle is the common work by anchor cable and stake
With joint resistance Thrust of Landslide, in engineer applied, anchored pile has that difficulty of construction is big, and construction quality is unmanageable to be lacked
Point, and due to the stress relaxation effect of anchor cable, often it is difficult to ensure that its long-term consolidation effect.In addition, anchored pile is general not

Plate type retaining wall, but this retaining structure has larger defect, Zhi Nengzhi no matter from theoretical, construction method and economic benefit
The very small-scale landslide of reason.
Subsequent someone develops framed revetment.But purpose of searching to the bottom, it is intended merely to resist soil pressure.And soil pressure
Power also has the horizontal active earth pressure promoted in addition to top-down gravity pressure, and this active force comes to advancing slip
The top soil body of shifting trend, and the deep soil for being then only embedded in front lower place of the provided resistance on the other side of energy,
This species resistance includes producing to be depended in the subgrade reaction of soil-baffling structure substrate and the passive earth pressure of front side, its overall strength
The bearing area two indices of natural compressive strength and the innovation soil structure of foundation soil.And retaining wall has been force transferring structure in itself
Effect, no matter its structure change and intensity size itself, key simply requires that it can transfer more subgrade reactions and passive
Soil pressure.And the framed revetment of framed revetment, especially pile foundation load-bearing, itself is thin fine, and bearing area has
Limit, only relies on pile top or cushion cap bottom surface provides the meagre passive earth pressure in meagre subgrade reaction and pile body forward position, it is clear that be not
Sufficiently achieve current demand.And broken pile, floating stake, askew stake phenomenon inevitably occur during pile foundation construction, more can be big
Amplitude cuts down only meagre resistance.Therefore, its reliability can not be with the gravity type Huo templates of Daoing Xia on subsoil
Formula retaining wall phase is right, greater risk be present, and probably triggers landslide landslide accident in complicated work progress,
Great threat is caused to workmen's personal safety.
In addition, and in the case of many landslides, surface rain washes away, soaks and causes soil moisture content too high, native
Qualitative change, cracking loss are to cause one of principal element of problem all the time, the above either anchor cable formula retaining wall or gravity type
Retaining wall, all can not fundamentally solve the technical problem.
The content of the invention
It is an object of the present invention in view of the shortcomings of the prior art, there is provided a kind of net for preventing landslide of well stake formula

Condition carries out earth-retaining reinforcing, so as to fundamentally solve the problems, such as landslide.
To achieve these goals, it is provided by the invention prevent landslide structure be：It is domatic along contour in massif
Compacting type earth-retaining grade beam is arranged in direction, thus according to landform can with a plurality of earth-retaining grade beam of distributed arrangement, earth-retaining grade beam it
Between along contour arrange continuous overboard well, and arrange that intercepting ditch connects the opening of the overboard well of same contour；Institute
The compacting type earth-retaining grade beam stated gos deep into basement rock with prestressed ground anchors and establishes anchor point, and pouring grade beam with armored concrete will be the same as first-class
The prestressed ground anchors of high line is concatenated.
The foregoing structure for preventing landslide, compacting type earth-retaining grade beam can be arranged according to domatic physical features, be particularly
Big domatic of the gradient continuously intensive can arrange some compacting type earth-retaining grade beams to reinforce soil layer；Foregoing overboard well also may be used
With according to domatic physical features arrangement, the gradient is small and region that area is larger can continuously arrange the overboard well of some rows so that ground
The current of table can fully be inducted into underground.
Foregoing prestressed ground anchors and the distribution density of overboard well can have more orographic condition and calculate decision.
The foregoing structure for preventing landslide, described overboard well, its structure includes well stake and prefabricated mozzle, described
Well stake be filter well stake, well stake depth is at least up to water-bearing layer, and described prefabricated mozzle is infiltration mozzle, wherein oozing
Water water conservancy diversion tube wall, which is provided with micropore, allows the water outside pipe to penetrate into pipe.
The foregoing structure for preventing landslide stated, it is characterised in that described intercepting ditch, its section are infundibulate so that
The current of earth's surface can be collected by intercepting ditch enters underground by overboard well stream, its flowing on domatic surface is reduced, so as to reduce
Current wash away to slope structure.
