Return packet mode reinforced soil retaining wall (greening) and refer to the reinforced soil retaining wall that adopts geo-grid to return the domatic filler formation of bag, the reinforced soil retaining wall of this form links together levels geo-grid by pitman, make whole reinforced soil retaining wall form an integral body, there is good globality.But the panel rigidity of this form retaining wall is approximately zero, its design scope of application is subject to gradient restriction (gradient generally should not be greater than 70 °), and when this class barricade is built near water in addition, erosion resistibility is poor.
Modular reinforced soil retaining wall refers to that body of wall adopts Fill Reinforced With Geogrids, and metope adopts precast concrete module, and reinforced soil retaining wall body of wall reinforced grating being joined together to form by pitman.The rigidity of this form retaining wall individual module is very large, but with regard to the high scope of whole wall, the integral rigidity of module metope is little, and globality is poor, metope horizontal distortion large (when especially wall height is higher).
How to design a kind of concrete slab reinforced soil retaining wall, can gather the advantage of returning packet mode reinforced soil retaining wall and two kinds of forms of modular reinforced soil retaining wall, and can overcome the shortcoming of its existence, this is the art technical problem urgently to be resolved hurrily.
Summary of the invention
The problems referred to above and the deficiency that in order to solve prior art, exist, the utility model provides a kind of concrete slab reinforced soil retaining wall, the advantage of packet mode reinforced soil retaining wall and two kinds of forms of modular reinforced soil retaining wall is returned in set, large, the unsuitable occurred level distortion of integral rigidity, high applicable to retaining wall height, the gradient is steep, domatic situation near water.
The purpose of this utility model is achieved by the following technical solution: a kind of concrete slab reinforced soil retaining wall, comprise surface layer and Fill Reinforced With Geogrids body of wall, it is characterized in that: described surface layer is integral cast-in-situ concrete slab, described cast-in-situ concrete panel bottom is provided with concrete continuous footing, described Fill Reinforced With Geogrids body of wall is for returning packet mode Fill Reinforced With Geogrids body of wall, described in return between packet mode Fill Reinforced With Geogrids body of wall and described integral cast-in-situ concrete slab and link together by steel mesh reinforcement and pre-buried anchor bar.
Improvement to technique scheme: described in return packet mode Fill Reinforced With Geogrids body of wall and adopt geogrids layer and packing layer to replace pressing to form.
Further improvement to technique scheme: described geogrids layer adopts unidirectional geo-grid, connects by pitman between the levels of described unidirectional geo-grid, and described packing layer is gravelly soil, gravelly soil and fine grained soils water permeability filler.
Further improvement to above-mentioned upper technical scheme: the material of described unidirectional geo-grid and pitman is high density polyethylene (HDPE).
Further improvement to technique scheme: described in to return the side that packet mode Fill Reinforced With Geogrids body of wall is connected with described integral cast-in-situ concrete slab be formed by non-woven geotextile and earth bag metope domatic, described integral cast-in-situ concrete slab is connected domatic that non-woven geotextile and earth bag metope form with pre-buried anchor bar by steel mesh reinforcement.
Further improvement to technique scheme: described in return packet mode Fill Reinforced With Geogrids body of wall and be provided with from the bottom to top rectangular plastic weeper drain and PVC gutter.
The utility model compared with prior art has the following advantages and good effect:
The utility model adopts the flexible form that packet mode Fill Reinforced With Geogrids body of wall combines with integral rigidity cast-in-situ concrete panel of returning, the panel of the utility model retaining wall is the mixed native panel of integral cast-in-situ, the body of wall of retaining wall adopts geogrids layer and packing layer to replace pressing and forms, geogrids layer adopts unidirectional geo-grid, between levels geo-grid, by pitman, connects.Large, the unsuitable occurred level distortion of integral rigidity, high applicable to retaining wall height, the gradient is steep, domatic situation near water.Thereby solved flexibility, to return packet mode reinforced soil retaining wall erosion resistibility poor, the problem such as the problem that the gradient can not be excessively steep has solved rigid matrix formula reinforced soil retaining wall integral rigidity little simultaneously, and horizontal distortion is large.The utlity model has the features such as stability is good, and speed of application is fast, and anti-seismic performance is superior, and integral rigidity is large, and horizontal distortion is little, widely applicable.
