Description
Technical field
The utility model relates to the reinforced earth retaining wall, particularly multi-stag reinforced earth retaining wall that uses in road (railway, highway) the roadbed embankment engineering (embankment).
Background technology
Reinforced earth retaining wall is ripe roadbed retaining engineering technology, in reclamation works such as railway, highway, harbour application is often arranged all, has obtained development faster since coming out the sixties in last century, and has become better and approaching perfection day by day.After nineteen ninety, relevant industrial department such as railway, highway, all successively issued corresponding design specifications (as " highway reinforced earth design specifications " and " railway bed retaining structure design specifications "), but what these standards defined all is the single-stage reinforced earth retaining wall, and the major defect of single-stage wall is to build De Taigao.Relevant studies show that, single-stage reinforced earth retaining wall body of wall is too high, and the lacing wire pulling force design formulas in the reinforced earth also must further be inquired into; In addition, construction precision was difficult to hold after the wall height was still arranged, the too high many unfavorable factors such as engineering monolithic stability that influence of center of gravity, so, in " the railway bed retaining structure design specifications " issued as the Ministry of Railways, regulation " height of reinforced earth retaining wall should not be greater than 10m on I level main line, should make particular design when wall is tall and big during in 10m " just.
Japan nineteen ninety and 1993 the disclosed in succession patent No. be that its invention achievement all is the single-stage reinforced earth retaining wall in the patent gazette of flat 2-261122 peace 5-48819, inventor island Tian Junjie, be the at present domestic retaining structure that generally uses.
In road construction, tunnel and high cutting (excavation) engineering often appear, cause a large amount of wastes, difficult problem during the processing waste designs often not only increases investment, and also there is very adverse influence in environment, if this tunnel, highway section, deep-cut with the gully and link to each other, the influence that brings is bigger.Because the embankment filled height is restricted, high embankment is the key area of subgrade defect often, how to avoid using in engineering; A retaining of general retaining engineering is controlled by Stability Analysis of Structures and economic indicator highly, with the railway shoulder retaining wall is example, generally speaking, and when highly reaching 16m, unit price will be above bridge (promptly not as construct a bridge at this place economy), and the waste that the curb retaining wall receives is very limited; Under this condition, often pass through, cause difficulty for the processing of waste, and increase investment with the bridge scheme.
The utility model content
Technical problem to be solved in the utility model provides a kind of multi-stag reinforced earth retaining wall that utilizes the single-stage reinforced earth retaining wall to build to build, and breaks through the restriction that reinforced earth retaining wall is subjected to the single-stage wall to prop up the retaining height, the more wide purposes of developing reinforced earth retaining wall.
The technical problem that the utility model proposed is to solve like this: a kind of multi-stag reinforced earth retaining wall, comprise single-stage reinforced earth retaining wall, outer side panel, lacing wire, connect overlapping building by at least two above single-stage reinforced earth retaining walls, the end of two adjacent single-stage reinforced earth retaining walls is provided with faulting of slab ends, and integral body is pagoda or stepped.
The building the mode of building and to adopt the mode of one-sided multi-stag, bilateral symmetrical expression and bilateral asymmetric reinforced earth retaining wall to build to build of multi-stag reinforced earth retaining wall.
Advantage of the present utility model is: opened up the effective way that increases the embankment filled height, because reinforced earth retaining wall is a flexible structure, non-deformability is strong, not high to the ground requirement for bearing capacity yet, after building up the reinforced earth retaining wall of multistage form, not only can break through the retaining structure height that limits in the design specifications, under certain condition, can replace setting up the viaduct scheme and reduce investment outlay,, receive worker's point of a large amount of wastes at needs according to measuring and calculating, adopt multistage reinforced earth retaining wall New Scheme, can reduce investment outlay 8%～50% than the bridge scheme, the utility model retaining structure has the function of receiving a large amount of wastes, and is very favourable to environmental protection and construction organization.

The specific embodiment
Below in conjunction with accompanying drawing multi-stag reinforced earth retaining wall provided by the utility model is elaborated.
Shown in Fig. 1～4.A kind of multi-stag reinforced earth retaining wall, comprise single-stage reinforced earth retaining wall, outer side panel, lacing wire, connect overlapping building by at least two above single-stage reinforced earth retaining walls 1, the end of two adjacent single-stage reinforced earth retaining walls 1 is provided with faulting of slab ends 2, and integral body is pagoda or stepped.
Shown in Fig. 2～4, the building the mode of building and can adopt the mode of bilateral symmetrical expression, bilateral asymmetric, one-sided multi-stag reinforced earth retaining wall to build to build of multi-stag reinforced earth retaining wall.
Have at the ground basal plane under the condition of certain cross fall (ubiquity), according to total filled height this structure is divided into some levels, each grade highly is controlled in the reinforced earth retaining wall height of design specifications restriction, build by the single-stage reinforced earth retaining wall step by step, leave faulting of slab ends between every grade, the faulting of slab ends width is calculated according to inspection and is determined, generally at 2～4m; The lacing wire configuration of each grade is determined according to dynamic and static load that bears on the road surface and the suffered static load inspection calculation of this grade, and is carried out the stability inspection step by step and calculate; Every grade of reinforced earth panel and lower floor reinforced earth contact position are provided with footing beam, with anti-deformation.If the next stage reinforced earth retaining wall is stable, can be considered artificial platform, build II level reinforced earth retaining wall thereon; If II level reinforced earth retaining wall is stable, still can be considered artificial platform, can build III level reinforced earth retaining wall thereon, by that analogy, can be as required up one until N level reinforced earth retaining wall, as long as this place's bearing capacity of foundation soil meets the demands, can solve the technical problem that high embankment is difficult to overcome.
