Description

Shunting slope roadbed structure

Technical Field

The utility model relates to a highway engineering technical field especially relates to a shunting slope roadbed structure.

Background

The 2/3 of the land area in China is a mountain land, so many highways need to be built on a hillside, however, due to the difference of foundations, compared with a flat land roadbed, the hillside roadbed needs to be filled and dug greatly during construction, and the problems of large digging amount, large supporting structure, high cost, large damage to the natural environment and the like exist. The mountain road has the condition of large-scale vehicle and small-size vehicle mixed flow, and the speed of a motor vehicle is different to cause more overtaking, causes current efficiency slow, also should take place danger. Particularly, when small vehicles exceed large vehicles, the road traffic safety is threatened all the time due to the problems of large sight line shielding, long overtaking mileage, large blind areas of large vehicles and the like.

The utility model aims to solve the technical problem that prior art's defect is overcome, a shunting slope roadbed structure is provided.

The utility model discloses the technical problem that will solve adopts following technical scheme to realize.

The utility model provides a shunting side slope roadbed structure, includes as for the enlarged basis in the side slope, vertical roof beam arranges in on the enlarged basis, support upper portion roadbed structure on the vertical roof beam, upper portion roadbed structure transversely sets up, and sets up the multilayer, the last stock anchor that is equipped with of upper portion roadbed structure goes into the side slope.

The utility model discloses a further technique:

preferably, the upper layer of the upper roadbed structure is paved with a pavement, a drainage ditch along the highway direction is arranged on the outer side of the pavement, a drainage hole is reserved in the outer wall, the drainage ditch along the highway direction is arranged on the inner side of the pavement, and a drainage channel is pre-buried in the roadbed structure.

Preferably, the inner side of the upper roadbed structure is provided with a concrete bent-up end, and the concrete bent-up end is arranged close to the slope surface.

Preferably, the support beams are arranged on the inner side of the upper roadbed structure of the lower layer and supported below the upper roadbed structure of the upper layer.

The utility model discloses beneficial effect:

the utility model provides a side slope roadbed structure, the upper portion roadbed structure of multilayer form shunts oversize vehicle and small-size vehicle, has accelerated current efficiency, has avoided dangerous overtaking or sight shielding problem that big car and small car mixed flow caused simultaneously; meanwhile, large excavation and large filling are avoided, the high retaining wall is adopted, the construction is simple, the cost is low, the influence of the structure on the mountain is small, and the environment is protected.

wherein: 1. an anchor rod; 2. bending up the concrete; 3. side slope; 4. an upper subgrade structure; 5. a vertical beam; 6. expanding the foundation; 7. a drain hole; 8. a drainage ditch; 9. and supporting the beam.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

The utility model provides a shunting side slope roadbed structure, including as for the enlarged basis 6 in the side slope 3, vertical roof beam 5 arranges in on the enlarged basis, support upper portion roadbed structure 4 on the vertical roof beam, upper portion roadbed structure transversely sets up, and sets up the multilayer, the last anchor that is equipped with of upper portion roadbed structure goes into the side slope.

And a concrete bent-up end 2 is arranged on the inner side of the upper roadbed structure, and the concrete bent-up end is arranged close to the slope surface.

The road surface is laid on upper portion roadbed structure upper strata, sets up the slope that accords with the standard in the road surface structural layer, and the road surface outside sets up along highway direction's escape canal 8 to wash port 7 is reserved at the outer wall, the inboard escape canal 8 that sets up along highway direction in the road surface, pre-buried drainage channel in roadbed structure. And meanwhile, the connecting part of the bottom of the drainage ditch and the connecting pipeline is provided with anti-filtration geotextile to prevent sludge from being blocked.

In the first embodiment, as shown in fig. 1, the investigation on the demand and traffic volume in the early stage is performed, and the shunting type roadbed structure mainly aims at mountain roads mainly including freight transportation and large vehicle traffic. The larger space of the upper roadbed is beneficial to the passage of large vehicles.

In order to prevent overlong bending moment of the upper roadbed and large load of a cart, a supporting beam 9 is arranged on the lower roadbed close to the mountain side.
