Reinforced soil retaining wall is to utilize level, lacing wire and the frictional force between the filler alternate, that be arranged in the filler to stratification to stablize the soil body.The effect of panel is to extrude from the side in order preventing to banket between lacing wire and to make structure have definite shape, beautifies the appearance and modeling of structure.Panel itself is a rigidity, but the metope system is flexible.Though reinforced earth retaining wall can be accomplished the 10m height,, be easy to generate moderate finite deformation because its flexibility is excessive, because its plate thickness is thinner, and generally presses constructional reinforcement, when the retaining wall height is higher, easily produce distortion and cause appearance uneven, apparent aesthetic property is poor.In addition, shingle nail is that the lacing wire node need be set, and wears muscle hole etc. as pre-buried steel draw ring, steel plate anchor head or reservation, complex structure, and lacing wire is fixedlyed connected with panel, is unfavorable for improving efficiency of construction.
The utility model content
Technical problem to be solved in the utility model provides a kind of Cantilevered type retaining wall reinforcement composite structure, and this structure can be increased to 10～12m with the raising of cantilever retaining wall, and is convenient to the operation of mechanization compacting filler.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Cantilevered type retaining wall reinforcement composite structure of the present utility model, comprise cantilever retaining wall and at the filler of the inboard placement in layers of its upright arm plate, it is characterized in that: level in the described filler, alternate, be furnished with lacing wire to stratification, each lacing wire forms the inflection section near the end turnup of upright arm plate, is enclosed with the inclusion enclave that is made of the compacting filler in the inflection section.
The beneficial effects of the utility model are, inclusion enclave is by the lacing wire of horizontal inflection, the lateral earth pressure stress that provides enough horizontal drags to produce with balance filler and load, or reduce to act on horizontal earth pressure value on the cantilever retaining wall body of wall, make the raising of cantilever retaining wall can reach 10～12m, and be convenient to the operation of mechanization compacting filler, the purpose that reaches structure self balance and save construction investment.Upright arm chest slope ratio of slope has good receipts slope effect to the embankment high slope in 1: 0～1: 0.05 scope; Base plate is flat, and width is bigger, and it requires relatively lowly to bearing capacity of foundation soil, so the ground scope of application is more extensive; The existence of lacing wire has been equivalent to improve the mechanics index of physics of filler, compares with existing cantilever retaining wall, and the compliance of its filler is wider, filler is lacked and needs receive the hillside fields section, and its advantage can not be substituted; Wall by the design of ultimate limit state method, meets the international trend that the engineering structures standard is revised by Reliability Theory comprehensively as reinforced concrete structure, is the more wide retaining structure form of a kind of application prospect.
Description of drawings
This manual comprises as next width of cloth accompanying drawing:
Fig. 1 is the sectional schematic diagram of a kind of Cantilevered type retaining wall reinforcement composite structure of the utility model.
Parts shown in the figure, toponym and pairing mark: cantilever retaining wall 10, upright arm plate 11, lacing wire 20, inflection section 20a, filler 30, inclusion enclave 30a.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, a kind of Cantilevered type retaining wall reinforcement composite structure of the present utility model comprises cantilever retaining wall 10 and at the filler 30 of its upright arm plate 11 inboard placements in layers.Levels in the described filler 30, alternate, be furnished with lacing wire 20 to stratification, each lacing wire 20 is enclosed with the inclusion enclave 30a that is formed by the compacting filler near end turnups formation inflection section 20a of upright arm plates 11 in the inflection section 20a.Inclusion enclave 30a is by the inflection section 20a lacing wire of horizontal inflection, the lateral earth pressure stress that provides enough horizontal drags to produce with balance filler 30 and load, or reduce to act on horizontal earth pressure value on cantilever retaining wall 10 bodies of wall, make the raising of cantilever retaining wall 10 can reach 10～12m, and be convenient to the operation of mechanization compacting filler, the purpose that reaches structure self balance and save construction investment.
In the subgrade construction design, tend to run into because of the demand that other engineering or building are arranged and to receive the situation on slope to side slope of embankment, the upright arm chest slope ratio of slope of cantilever retaining wall reinforcement of the present utility model structure is in 1: 0～1: 0.05 scope, and is obvious to the receipts slope effect of embankment high slope.Compare with existing reinforced soil retaining wall, the retaining wall base plate is flat, and width is bigger, its to bearing capacity of foundation soil require relatively low, therefore comparatively extensive to the ground scope of application.Wall by the design of ultimate limit state method, meets the international trend that the engineering structures standard is revised by Reliability Theory comprehensively as reinforced concrete structure, is the more wide retaining structure form of a kind of application prospect.The existing cantilever retaining wall of requirement of wall back of the body filler index is low, and the existence of lacing wire has been equivalent to improve the mechanics index of physics of filler, and is therefore wider to the compliance of filler, filler is lacked and needs receive the hillside fields section, and its advantage can not be substituted.
Described lacing wire 20 can be adopted thin steel band, geosynthetics (polypropylene geotechnique band, steel are moulded composite earthwork band, geo-grid).Because the compressive strength of high-quality geo-grid is near the intensity of mild steel, its eyelet is to the locking action of filler 30 in addition, the passive hindrance function of 30 pairs of fence of filler, make geo-grid in filler 30 the resistance to plucking ability or grid to the consolidation effect of filler 30 also apparently higher than the strip-type lacing wire, the therefore described lacing wire 20 suitable preferred geo-grid that adopt.The horizontal inflection parcel section 20a length of described lacing wire 20 can be determined by calculating, relevant with the lateral earth pressure stress that cohesion, angle of friction and filler 30 and the load of 30 of lacing wire 20 leveling course spacings, lacing wire 20 and fillers produce, if inflection section 20a length is oversize, can increase construction investment greatly, cause certain waste, and inflection section 20a length is too short, then can not provides effective enough drags again with the equilibrium level soil pressure, therefore, generally speaking should not be less than 2m.
