Abstract
A road high and steep slope anti-foreign-material structure prevents a road from being influenced by foreign material intrusion and avoids the problem that cantilevers of high and steep slope excavation strong retaining and lower retaining structures are long caused by the reason that an abrupt slope road is built. The road high and steep slope anti-foreign-material structure comprises reinforcing piles (1), joists (2), tunnel open caves(3), backfilling plain concrete (4), and backfilling soil (5), wherein the reinforcing piles are arranged lengthwise along a line at intervals, the lower portions of the reinforcing piles extend into a slope stable rock and soil layer, the joists are arranged on the top portions of the reinforcing piles (1) and are connected with the reinforcing piles in a rigid mode, hanging part, of the tunnel open cave, outside the slope are arranged on the joists, the backfilling plain concrete is poured on the top portions of the joists (2) and outside the tunnel open caves (3), and the backfilling solid (5) is filled among the top portions of the tunnel open caves (3) and slope faces of the slope.
Description
Technical field
The utility model relates to railway, highway engineering, particularly the anti-foreign matter structure of a kind of road high gradient slope.
Background technology
High-grade railway, highway begin to build in a large number in the Southwestern China mountain area, because the special geology landform of Southwest Mountainous Areas and the high request of circuit line style, highway construction unavoidably appears through the high gradient slope section, advanced road is high-speed railway particularly, foreign matter is invaded very harmful to road operating safety, taking is possible foreign bodies removal very difficult or even impossible fully, urgently needs the anti-foreign matter structure of a kind of high gradient slope to solve problems for this reason.
The utility model content
Technical problem to be solved in the utility model provides the anti-foreign matter structure of a kind of road high gradient slope, is not subjected to the foreign matter intrusion effect with road, and avoids propping up by force gear and bottom retaining structure cantilever and the difficulty such as growing because building Excavation of High And Steep Slopes that steep slope subgrade causes.
The technical scheme that its technical problem that solves the utility model adopts is:
The anti-foreign matter structure of road high gradient slope of the present utility model is characterized in that it comprises: reinforcing pile, arrange along circuit longitudinal separation, and its underpart extends into the stability of slope rock-soil layer; Joist is arranged at the reinforcing pile top and also is rigidly connected with it; The tunnel open cut tunnel, the outside, abrupt slope overhanging portion places on the joist; The backfill plain concrete is built in joist top and the tunnel open cut tunnel outside; Backfill is filled between open cut tunnel top, tunnel and side slope surface.
The beneficial effects of the utility model are; can effectively protect road not to be subjected to the foreign matter intrusion effect; can avoid simultaneously propping up by force gear and bottom retaining structure cantilever and the difficulty such as growing because building Excavation of High And Steep Slopes that steep slope subgrade causes; have wide popularizing application prospect, particularly build the anti-foreign matter intrusion of high-speed railway for the Southwestern China area and have good practical value.
Description of drawings
This manual comprises such as next width of cloth accompanying drawing:
Fig. 1 is the cross-sectional drawing of the anti-foreign matter structure of the utility model road high gradient slope.
The title of member shown in the figure and corresponding mark: reinforcing pile 1, joist 2, tunnel open cut tunnel 3, backfill plain concrete 4, backfill 5.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, the anti-foreign matter structure of road high gradient slope comprises: reinforcing pile 1, arrange along circuit longitudinal separation, and its underpart extends into the stability of slope rock-soil layer; Joist 2 is arranged at reinforcing pile 1 top and also is rigidly connected with it; Tunnel open cut tunnel 3, the outside, abrupt slope overhanging portion places on the joist 2; Backfill plain concrete 4 is built in joist 2 tops and tunnel open cut tunnel 3 outsides; Backfill 5 is filled between tunnel open cut tunnel 3 tops and side slope surface.
The utility model is born 3 outside overhanging portion deadweights of tunnel open cut tunnel and is reinforced gradient slope by reinforcing pile 1, guarantees the stable of gradient slope.Utilize joist 2 to support tunnel open cut tunnel 3 outside overhanging portions, backfill plain concrete 4 increases tunnel open cut tunnel 3 horizontal restraint power.Utilize cushioning effect and the great slope of backfill 5, greatly alleviate the foreign matter intrusion to the percussion of tunnel open cut tunnel 3 and allow rapidly foreign matter roll and leave.Can effectively protect road not to be subjected to the foreign matter intrusion effect; can avoid simultaneously propping up by force gear and bottom retaining structure cantilever and the difficulty such as growing because building Excavation of High And Steep Slopes that steep slope subgrade causes; have wide popularizing application prospect, particularly build the anti-foreign matter intrusion of high-speed railway for the Southwestern China area and have good practical value.
The spacing of described reinforcing pile 1 is generally 5～7m, and stake is long to be needed to guarantee the settlement request of tunnel, top open cut tunnel 3 and guarantee the stable of gradient slope.The inverted arch section of described tunnel open cut tunnel 3 must together be built with backfill plain concrete 4 and is integrated, and open cut tunnel 3 crown section thickness in tunnel are suitably strengthened, and makes it to have certain impact resistance.The width that fills of described backfill 5 surpasses tunnel open cut tunnel 3 the highest arch crown parts, the palpus grinding compacting, and the outward-dipping formation in its top layer is not less than 10% the gradient, and the surface is removed grass-seed and is afforested anti-rain drop erosion.
Some principles of the anti-foreign matter structure of the above the utility model road high gradient slope that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the utility model is applied for.
