Description
Technical field
The present invention relates to Geotechnical Engineering field, in particular to a kind of wall-mounted drainage anchor rod barrier wall structure.
Background technique
River channel below dams are because reservoir level periodicity fluctuation makes reservoir periphery be submerged soil periodicity exposure in the water surface
Special area.The falling zone range of large reservoir is often very big, for example the Three Gorges Reservoir engineering built up for 2009 disappears
Height of settling in an area reaches 30m, and the falling zone height of Jinsha jiang River white crane beach reservoir engineering built up in 2022 is bigger, reaches 60m.Position
Periodical action of soaking, the groundwater seepage effect etc. of library water and underground water, wind are subject in the Rock And Soil of river channel below dams
Change effect is stronger, so that riverside rebuilding phenomenon happens occasionally.When library, bank has buildings or structures, riverside rebuilding may be threatened
The safety of buildings or structures.
In order to develop reservoir area economy, it is built, build large-scale buildings or structures (as high speed is public building or reservoir periphery will be built
Road) often it is necessary, riverside rebuilding is usually unavoidable to the influence problem of buildings or structures safety.For example, Jinsha
The beach Jiang Baihe reservoir engineering will be built up in 2022, in order to develop reservoir area and local economy, have a plurality of high-grade highway
Or it will be built in reservoir area and the reservoir zone of influence.Due to white crane beach Reservoir region special topography and geomorphology and geological conditions, reservoir area
The bridge accounting of high-grade highway is often higher, and bridge foundation mostly uses pile foundation, and is arranged in the cheuch of river channel below dams more
In side slope.Although most ditch valleyside slopes rock side slope steep for landform, rock crushing, and it is located at river channel below dams, white
After crane beach reservoir builds up operation, a possibility that side slope generation local buckling, is larger on the outside of ditch valleyside slope especially bridge foundation, makes
Bored Pile of Bridge is easy exposed, impaired, need to take reasonable measure and Bored Pile of Bridge protected.
The case where reinforcing slopes on the outside of ditch valleyside slope bridge pile foundation, theoretically, adoptable side are only needed for such
Slope reinforcement technique is more, can generally be divided into three classes, first is that anchorage technology (such as shotcrete, anchor pole, anchor cable are reinforced), second is that branch
Gear technology (such as barricade, friction pile, pile plate wall), third is that presser feet technology (such as slope angle backfills the cubic metre of earth and stone).
The principle of anchorage technology is Rock And Soil with anchor pole, anchor cable etc. that the anchoring in rock and soil of possible unstability is stable in slope
On.With here the shortcomings that be that anchor pole (rope) construction may damage Bored Pile of Bridge, anchoring effect of anchor pole (rope) is with library water week
The effect of phase property may gradually be lost, and not can effectively prevent the local buckling of reinforcing side slope.
The principle of supporting and retaining system technology is to be limited using the self stability of retaining structure by the deformation of supporting and retaining system Rock And Soil.Barricade is used
It is since ditch valleyside slope is steep in the shortcomings that place, barricade area of base is limited, and foundation bearing capacity is smaller, so that barricade homeostasis
Property it is insufficient;The shortcomings that friction pile or pile plate wall are used in place is that difficulty of construction is big, and economy is poor.
The principle of presser feet technology is to be limited using the self stability of backfill Rock And Soil by the deformation of protection Rock And Soil.It can
For mainly being controlled by landform herein, if orographic condition does not allow, it is not available.
In addition, bank slope Changes in underground water variation caused by reservoir level is gone up and down is also a matter of concern, underground
Water lever fluctuating acts on the strength deterioration for not only making bank slope Rock And Soil, but also osmosis of the underground water to outside slope is likely to straight
Connecing leads to slopes unstability.
In consideration of it, being easy that part occurs because of Reservoir Water Level for slopes on the outside of reservoir drawdown band ditch valleyside slope bridge pile foundation
Unstability and the situation for influencing Bored Pile of Bridge safety, it would be highly desirable to research and develop and a kind of be suitable for large reservoir falling zone bank cheuch area Bridge Pile
The engineering technology of basis protection.
Summary of the invention
