Detailed Description
Example (b):
the structure diagram of the utility model is shown in fig. 1, the bank protection structure of the utility model comprises a stepped ecological retaining wall 1, a backfill stone 2 and a concrete bottom plate 3, wherein the stepped ecological retaining wall 1 is arranged on the slope of the bank, the concrete bottom plate 3 is fixed on the plane of the slope bottom of the bank, and the backfill stone 2 is arranged between the slope of the bank and the stepped ecological retaining wall 1.
In this embodiment, the outer sides of the bottom of the stepped ecological retaining wall 1 and the concrete bottom plate 3 are provided with protection feet 4.
In this embodiment, the stepped ecological retaining wall 1 includes a plurality of hollow frames 11, a layer of hollow frames 11 horizontally arranged together is built on the bottom plane of the bank slope along the length direction of the river, a second layer of hollow frames is built on the first layer of hollow frames along the bank slope until the top of the bank slope, a stepped bank slope is formed, each hollow frame 11 on the upper layer is pressed between two hollow frames 11 on the lower layer, finally, soil is filled in each hollow frame 11, and plants are planted in the hollow frames on each layer.
In this embodiment, the gaps between the hollow frames 11 are connected by concrete.
In this embodiment, the contact area of the upper hollow frame 11 against the lower hollow frame 11 is one third of the area occupied by the entire hollow frame 11.
In this embodiment, soil is filled in each hollow frame 11, and plants are planted in the hollow frames of each layer.
In order to facilitate installation, the stepped ecological retaining wall 1 is further provided with a hoisting hole 5. In this embodiment, cascaded ecological barricade 1 is equipped with 3 hole for hoist 5, and the centre of a circle of 3 hole for hoist 5 is connected for triangle-shaped.
Furthermore, the method is simple. The two ends of the stepped ecological retaining wall 1 are also provided with bolt connecting holes 6 for connecting the adjacent stepped ecological retaining walls 1.
In this embodiment, the backfill stones 2 are crushed stones. The backfill thickness of the backfill stone 2 is 20 mm.
In this embodiment, the concrete floor 3 is a C25 concrete floor. The thickness of the concrete bottom plate 3 is 200 mm; the above-mentioned foot protector 4 is a riprap foot protector, and the thickness of the foot protector 4 is 500 mm.
In river regulation engineering, slope protection treatment is required for side slopes in order to ensure the safety of the side slopes and the environment of the side slopes in the traditional slope protection. The slope protection types commonly used at present comprise ecological frame retaining wall slope protection, concrete retaining wall slope protection, stone masonry retaining wall slope protection and other slope protection types. The comparison is as follows:
the ecological frame retaining wall revetment has great advantages in terms of cost and ecological property, is most widely used in concrete retaining wall revetment, has better reliable structural stability than other two schemes, has good anti-scouring performance, has better structural stability, has good greening effect of the step ecological frame retaining wall, can realize that a series of slope protection plants such as submerged plants, floating leaf plants, emergent aquatic plants, hygrophytes (arbors, shrubs, grasses) and the like are planted in sequence from the toe to the top of a slope, forms multi-level ecological protection, and forms a perfect ecological revetment system. Not only can satisfy the service function of retaining wall, still consider the coordination with the surrounding environment.
The ecological frame retaining wall revetment has the following difference with traditional stone masonry or concrete retaining wall:
the original traditional stone masonry construction difficulty is slightly high, auxiliary structures such as drain holes and settlement joints need to be arranged, and certain difficulty is caused to the stone masonry construction. And the masonry construction must have special machinery to assist the construction. For the construction time, the masonry retaining wall also has certain limitation, and can not be constructed in winter or rainy season, and the green lattice retaining wall has no limitation, and can be constructed at any time.
The most important point is that the ecological frame retaining wall revetment can be ecological, the concrete surface layer can not realize greening, and the ecological frame retaining wall revetment can realize greening. Soil is covered in the ecological frame box body and grass is planted, so that the greening effect can be realized quickly.
The third point is that the ecological frame retaining wall revetment has higher requirement on the foundation by the masonry stone and more complex design in the aspect of foundation treatment, and the net cage retaining wall has lower requirement on the foundation and basically does not need foundation treatment, so a great amount of foundation treatment cost can be saved.
The fourth ecological frame retaining wall revetment is maintained and the security for the masonry retaining wall in later stage on, and concrete retaining wall need check whether the wash port takes place to block up, whether take place inhomogeneous settlement, and does not need to maintain after ecological frame retaining wall revetment completion basically.
Therefore, the ecological frame retaining wall and bank protection is very suitable for building ecological landscape in river channel treatment engineering.
The specific manufacturing process of the utility model is as follows:
(1) material
The ecological frame is a precast concrete product. The production standard is basically 200 × 100 × 50 cm, and the production standard can also be customized by contacting a manufacturer after an order is submitted, and a general mold factory produces the mold according to a drawing provided by a customer so as to ensure that the mold meets the requirements of engineering. The hollow frame body is prefabricated by concrete, the interior of the hollow frame body is hollow, the height of the hollow frame body is 30 cm-40 cm, and the area of the hollow frame body is 0.25 square meter. Precast concrete is labeled C30.
(2) Construction of
The construction sequence is as follows: construction preparation → C30 concrete frame member making → cast-in-place rear greening concrete pouring → middle nutrient material preparation and installation → cast-in-place front greening concrete → filling alkali-removing agent, i.e. saline-alkali improved material → foreign soil and grass seeds are backfilled or directly paved with lawn.
The utility model is particularly suitable for being applied to a bank protection retaining wall form for building ecological landscape in river channel treatment engineering, and belongs to the innovative application of combining water safety and ecological landscape in river channel treatment engineering.
