Abstract
The invention discloses a high-steep side slope subgrade structure for a mountain area, which is used for effectively lowering the construction cost of a subgrade in a high-steep mountain area and avoiding the huge potential safety hazard existing in the excavation of a high-steep side slope. The structure comprises reinforced concrete long column piles (1), reinforced concrete short piles (2), reinforced concrete trimmer beams (3) and a reinforced concrete road surface (4), wherein the reinforced concrete long column piles (1) are arranged at the outer side of a high-steep subgrade side slope and are longitudinally arranged at intervals along the subgrade; anchor ropes (5) anchored with bedrock are vertically arranged at intervals on the reinforced concrete long column piles (1); the reinforced concrete short piles (2) are arranged at the inner side of a high-steep subgrade excavation side slope and are correspondingly arranged at intervals in parallel to the outer side reinforced concrete long column piles (1) along the longitudinal direction of the subgrade; the reinforced concrete trimmer beams (3) are fixedly connected with the tops of every group of corresponding reinforced concrete long column piles (1) and reinforced concrete short piles (2); and the reinforced concrete road surfaces (4) extend along the longitudinal direction of the subgrade and are poured on each reinforced concrete trimmer beam (3).
Description
Technical field
The present invention relates to railway bed, high gradient slope roadbed structure in particularly a kind of mountain area is to avoid occurring the existing huge potential safety hazard of excavation high gradient slope.
Background technology
Mountain road turns one of key condition that solves the mountain area economy development into, because mountain area geological environment fragility, landform are steep, builds a large amount of tunnels, bridge engineering, and then construction costs is huge.How under this geology, orographic condition, to build subgrade construction, become the problem that urgent need is studied, press for a kind of novel roadbed structure of invention and can guarantee to build roadbed safety, can reducing the construction costs again and compliance with environmental protection requirements.
Summary of the invention
Technical problem to be solved by this invention provides a kind of mountain area high gradient slope roadbed structure, can effectively reduce the construction cost that high steep mountain area roadbed is built, and avoids occurring the existing huge potential safety hazard of excavation high gradient slope.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Mountain area of the present invention high gradient slope roadbed structure is characterized in that it comprises: the stake of steel concrete long column, place the high steep roadbed side slope outside, and be provided with along roadbed longitudinal separation, vertically be arranged at intervals with anchor cable in the stake of steel concrete long column with the basement rock anchoring; The steel concrete stub places high steep roadway excavation side slope inboard, along roadbed vertically with the corresponding parallel interval setting of outside steel concrete stanchion; The steel concrete joist, fixed with it at the top of the corresponding steel concrete long column stake of each group, steel concrete stub; Along reinforced concrete pavement, build on each steel concrete joist along the roadbed longitudinal extension.
Described steel concrete long column stake bottom is imbedded in the stable side slope rock-soil layer.
The domatic soil nailing that is provided with of high gradient slope that described reinforced concrete pavement is following.
The invention has the beneficial effects as follows, can solve high steep mountain area builds the width of subgrade deficiency and causes the problem of deep-cutting cutting and can not guarantee subgrade stability, the pier of avoiding constructing a bridge deep-cuts high steep cutting or high pier is striden greatly, construction technology is simple, can effectively save construction investment, and compliance with environmental protection requirements, have wide popularizing application prospect.
Description of drawings
This manual comprises as next width of cloth accompanying drawing:
Fig. 1 is the cross-sectional configuration schematic diagram of mountain area of the present invention high gradient slope roadbed structure.
Position shown in the figure, member and pairing mark: steel concrete long column stake 1, steel concrete stub 2, steel concrete joist 3, reinforced concrete pavement 4, anchor cable 5, soil nailing 6.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
With reference to Fig. 1, high gradient slope roadbed structure in mountain area of the present invention comprises: steel concrete long column stake 1, place the high steep roadbed side slope outside, and be provided with along roadbed longitudinal separation, vertically be arranged at intervals with anchor cable 5 in the steel concrete long column stake 1 with the basement rock anchoring; Steel concrete stub 2 places high steep roadway excavation side slope inboard, along roadbed vertically with the 1 corresponding parallel interval setting of outside steel concrete stanchion; Steel concrete joist 3, fixed with it at the top of the corresponding steel concrete long column stake 1 of each group, steel concrete stub 2; Along the reinforced concrete pavement 4 of roadbed longitudinal extension, build on each steel concrete joist 3.The vertical applied force that the present invention makes full use of steel concrete long column stake 1 and steel concrete stub 2 overcomes high gradient slope the long very long shortcoming of the big and required stake of roadbed bottom retaining structure horizontal distortion is set, and places with reinforced concrete pavement 4 and satisfies width of the subgrade surface and assurance subgrade stability on the steel concrete joist 3.
Steel concrete long column stake 1 bottom need be imbedded in the stable side slope rock-soil layer, to bear the vertical applied force of road bed.Anchor cable 5 bundle numbers and hole count are determined according to steel concrete stanchion 1 Calculation on stability.Vertical spacing distance is imbedded side slope rock stratum situation and stressed definite according to steel concrete long column stake 1, is generally positioned at the middle and upper part of steel concrete long column stake 1 exposure outside the rock stratum.
With reference to Fig. 1, the domatic soil nailing 6 that is provided with of the high gradient slope of described reinforced concrete pavement below 4 is to guarantee the slope stability of high gradient slope.Thereby guarantee that steel concrete long column stake 1 and the stressed of reinforced concrete pile 2 meet the demands.
Described reinforced concrete pavement 4 is provided with one place, shrinkage joint along the vertical every interval 15～20m of roadbed in steel concrete joist 3 centers.The filling of pitch plank is adopted at the shrinkage joint, and according to width of the subgrade surface, steel concrete road bed 4 can be along the horizontal framing setting of road bed, and the framing width should be advisable with 4～10m, and the filling of pitch plank is adopted at the shrinkage joint between the width of cloth and the width of cloth.
The present invention has solved high steep mountain area effectively and has built the width of subgrade deficiency and cause the problem of deep-cutting cutting and can not guarantee subgrade stability, the pier of avoiding constructing a bridge deep-cuts high steep cutting or high pier is striden greatly, construction technology is simple, can effectively save construction investment, and compliance with environmental protection requirements, have wide popularizing application prospect.
Some principles of the above this mountain area high gradient slope roadbed structure that just explains through diagrams, be not be the present invention to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
