Description
Technical field
The present invention relates to soil-slope, landslide control technology, and in particular to a kind of deep fill slope pile foundation stabilized control system.
Background technology
At present, for the land-based area structure formed by deep fill slopes, the large deformation of slopes is backfilled, unstability is land-based area knot
Structure can not normal use even one of major control factors of unstability, deformation for bank slope of the presence and feature of backfill,
Failure mode and its scale have conclusive control action.When the angle of former slope surface is in a certain scope, or deep fill slopes
It is especially true during formation critical slip surface, absolute control action is played to the stability of slopes；Since backfill soil property is more loose
Soft, the side slope for backfilling formation is more easy to large deformation and unstability be in the presence of, thus it is such to be slid along deep fill slope sliding surface
The most important Damage Types of slopes and controlling object.
It is more typical slopes unstability type in engineering to be slided along slopes caused by the sliding of deep fill slope sliding surface.It is but existing
Having control method and technology to be disturbed there is construction side slope Rock And Soil, big, quantities is big, time-consuming, of high cost, and can
The problems such as skid resistance of offer is limited, consolidation effect is not ideal enough.Wherein, anchoring is commonly used in slope and land slide prevention and cure project
, one of main technical measures, it is tightly locked together on stratum by embedded anchor pole in the earth formation；But tradition
Anchoring process its be to provide anchor force at all, the cunning of side slope is prevented by the anchor force rather than skid resistance of anchor pole indirectly
It is dynamic, and the anchor force that can be provided is limited, thus the consolidation effect that land-based area structure side slope is formed to backfill is not ideal enough.Together
When, rock and soil slope landslide control engineering is also subject to the factors such as formation lithology, Rock-soil Mass Structure, geological structure, hydrogeology
Influence, and violent earthquake may be subject to act on, constitute a threat to engineering safety.
The content of the invention
Present invention aim to address the deficiency of traditional anchoring process, there is provided what a kind of anchoring structure was combined with friction pile
Pile foundation stabilized control system.
To realize that the technical solution that the object of the invention uses is a kind of such, deep fill slope pile foundation stabilized control system,
Including anchorage pier, anchor pole, friction pile and tension device.The friction pile is a reinforced concrete pile arranged vertically.It is described anti-
Sliding pile is arranged on the middle and lower part of landslide areas, and wherein slip mass is slided along sliding surface, and the lower floor of sliding surface is to stablize the soil body or rock
Stone.The lower end of the friction pile is deeply to stablizing in the soil body or rock.
The anchorage pier is embedded in the stable soil body or rock.The anchor pole is arranged perpendicular to friction pile.The one of the anchor pole
Friction pile top is fixed at end, and the other end is horizontal to be run through the landslide soil body and be fixed in anchorage pier.The tension device is installed on anchor
On bar, and in slip mass.Hinge is additionally provided with the anchor pole.The hinge is close to friction pile.
Further, the upper end of the friction pile also has the pile cover for being higher by slip mass surface.
Further, the anchorage pier is placed at least 1m below the stable soil body or rock.
Further, the anchorage pier is square or cuboid.The friction pile is cylinder or rectangular column.
Further, the friction pile is deeply to stablizing at least 2m in the soil body or rock.
The solution have the advantages that unquestionable, cooperated by anchor pole and friction pile, and make anchor pole and antiskid
Stake is mutually perpendicular to.Wherein certain depth within the soil body is stablized in friction pile insertion, and then ensures the stability of pile foundation；Set among anchor pole
Put hinge and tension device, it is ensured that the stabilization of pile foundation, reduces pile foundation level displacement.The configuration of the present invention is simple, easy for construction, cost is low
It is honest and clean, project progress can be made substantially to accelerate.
