In order to eliminate the potential safety hazard of too high retaining wall, normal adopt the mode of banketing before wall to reduce retaining wall to prop up the gear height, if the high 13m of wall for example, the 5m that bankets before wall, after banketing like this, a gear of retaining wall highly has been reduced to 8 meters, and retaining wall is just safely like this.The effect of banketing before wall is exactly: when having served as high barricade and be not moved, banketing produces the existing too high retaining wall of earth pressue at rest opposing and produces overturning or slip resistance analysis moment and horizontal thrust, stops too high retaining wall to produce and topples and sliding rupture; When having served as high barricade and be moved, banketing produces the existing too high retaining wall of passive earth pressure opposing and produces overturning or slip resistance analysis moment and horizontal thrust, stops too high retaining wall to produce and topples and sliding rupture.
In engineering, 6 the modes of banketing before wall that adopt reduce too high retaining wall retaining structure height more, as shown in Figure 1.The major defect of banketing before wall is exactly the soil that need to take one fixed width, and this to be urban development be difficult to accepts.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of existing too high retaining wall retaining structure height and little anchoring retaining structure for reducing existing too high retaining wall supporting height of land occupation area of reducing.
In order to solve the problems of the technologies described above, anchoring retaining structure for reducing existing too high retaining wall supporting height provided by the invention, the root of too high gravity retaining wall be provided with one be close to it hold up arm-type wall, the end that described too high gravity retaining wall is closed in the described bottom of holding up arm-type wall is connected with to described holds up arm-type wall to apply to the prestressed anchor of described too high gravity retaining wall one skew back downward pressure, the described bottom of holding up arm-type wall adopts to be hinged away from an end of described too high gravity retaining wall and is connected to the reinforced concrete pile of holding up arm-type wall to apply support force upwards to described.
Described hinge is the longitudinal bar that 3 intersections are inserted described reinforced concrete pile afterwards.
Adopt the anchoring retaining structure for reducing existing too high retaining wall supporting height of technique scheme, the overturning or slip resistance analysis moment equivalence of the generation of banketing before the moment M that holds up downward component and the reinforced concrete pile of the pressure N of arm-type wall to form two power of support force P of holding up arm-type wall due to the prestressed anchor pole pair and wall; Reinforced concrete pile and hold up hinge between arm-type foundation of wall can guarantee to hold up arm-type wall can produce the minor rotation needed, guarantee that moment M can effectively be applied on existing too high gravity retaining wall.The prestressed anchor pole pair holds up the horizontal component of the pressure N of arm-type wall to add the horizontal thrust of the reinforced concrete pile that hinge is transmitted, can with the horizontal force equivalence of banketing before wall and producing.
Above measure can guarantee that retaining structure of the present invention can be equivalent with the effect of banketing before wall, plays and reduces the effect that existing too high gravity retaining wall props up the gear height.
The present invention be exactly by adopt the arm-type wall system of prestressed anchor+reinforced concrete pile+cut with scissors+hold up produce with wall before the equivalent mechanics effect that bankets, play and reduce existing too high retaining wall retaining structure height and the little purpose of land occupation area, make its gear highly meet " building slope engineering rules " GB 50330-2002 requirement, eliminate safe hidden trouble.
