Description

Technical Field

[0001] The utility model relates to the field of embankments, in particular to a green and environmentally friendly urban road high-fill embankment protection structure. Background Art

[0002] Urban road greening is an important component of urban roads and accounts for a large proportion of urban greening coverage. With the increase in urban motor vehicles, traffic pollution has become increasingly serious. Using road greening to improve the road environment has become an urgent task. Urban road greening is also an important manifestation of urban landscape style. Therefore, the requirements for greening on urban roads are getting higher and higher. The high embankments of urban roads are affected by the ecological red line and do not have the space to slow down the slope, which is very prone to sliding damage. Therefore, retaining walls and pile-sheet walls are often used to limit the lateral deformation and instability of the embankment and ensure the long-term stability of the embankment. However, the amount of masonry reinforcement of retaining walls and pile-sheet walls is large and does not meet the environmental protection requirements of urban roads. It is also difficult to green, the environment is unsightly, and the visual effect of traffic is poor. Some slopes have poor drainage and retaining wall cracking, collapse and other disasters may still occur. Utility Model Content

[0003] In order to solve the problems raised in the above background technology, the utility model provides a green and environmentally friendly urban road high-fill embankment protection structure.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A green and environmentally friendly urban road high-fill embankment protection structure includes an embankment base layer, a gabion layer and a roadbed layer. The gabion layer is a multi-layer stacked gabion layer placed on both sides of the embankment base layer. The gabions are filled with stone blocks. The embankment base layer between the gabions on both sides is backfilled in layers to form a roadbed layer.

[0006] Further technology of this utility model:

[0007] Preferably, the gabion is divided into compartments.

[0008] Preferably, the exposed area of ​​each layer of gabion is wrapped with anti-filter geotextile.

[0009] Preferably, geocells are laid in the roadbed, and the geocells are tightly connected to the gabions along both sides of the road.

[0010] Preferably, a greening layer is provided on the outside of the gabion.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] (1) The gabion process is simple. It only requires steel bars to tie the gabions and fill them with stone or pebbles. The material source is wide and the masonry work is small.

[0013] (2) The two sides of the geocell are tied and connected with the steel cage, which can give full play to the reinforcement properties of the geocell and further improve the stability of the high fill embankment;

[0014] (3) A greening layer is set outside the gabion to achieve a good greening effect;

[0015] (4) The gabion has good water permeability. When encountering heavy rain and other seasons, it can timely drain the water from the slope, and the slope stability is good;

[0016] (5) Low cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further explained below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figure 1 , Figure 2 As shown, a green and environmentally friendly urban road high-fill embankment protection structure includes an embankment base layer 1, a gabion layer and a roadbed layer 3. The gabion layer is a multi-layer gabion 2 that is tied and stacked and placed on both sides of the embankment base layer. The gabions are filled with stone blocks, and the embankment base layer between the gabions on both sides is backfilled in layers to form a roadbed layer.

[0024] The gabion is divided into compartments, which makes it easier to fill the stone and avoids the reduction of stability due to the gabion being too large.

[0025] The exposed area of ​​each gabion is wrapped with anti-filter geotextile 4 to prevent the loss of fine soil on the slope.

[0026] The geocell 5 is laid in the roadbed and is tightly connected to the gabions along both sides of the road.

[0027] A greening layer 6 is provided outside the gabion. In order to facilitate adsorption, gaps and concave surfaces exist on the outside of the gabion, which can make the sprayed substrate more adsorbable and not easy to fall off. Suitable seeds of grass, flowers, shrubs, etc. can also be selected according to the needs of urban road greening.

[0028] In summary, the protective structures of urban road embankments must primarily address three key aspects: environmental friendliness, slope stability, and smooth drainage. Protective structures using gabions, geocell reinforcement, and sprayed greening can effectively address these issues and are an excellent solution for protecting urban road embankments.

[0029] The gabion itself has good water permeability, which can allow the water in the slope to be discharged out of the slope in time, avoiding the stability of the embankment from being submerged in water for a long time.

[0030] During the layered filling process, the use of geocells for reinforcement can further ensure the stability of the embankment.

[0031] The tight connection between the two sides of the geocell and the gabion steel bars can effectively prevent damage such as extrusion and deformation during the layered rolling process, and give full play to the reinforcement effect of the geocell.

[0032] Combined with the gabion embankment facade, the comprehensive slope can be made very small, achieving a good slope reduction effect and meeting the ecological red line requirements of urban roads.

[0033] Greening can be achieved by spraying the outside of the gabion. You can choose the ideal grass seeds according to the needs of urban roads. Because there are many gaps and concave surfaces between the slabs and pebbles on the facade of the gabion, the sprayed substrate has good stability and is not easy to fall off, which will achieve a good greening effect in the later stage.
