Large sash protection unit for water side slope and side slope protection structure

Technical Field

The utility model relates to a side slope protection unit and the side slope protective structure on water that adopts this unit, especially a big sash protective unit and side slope protective structure for side slope on water.

Background

With the deepening of the ecological civilized construction concept in China, the inland waterway slope protection project gradually changes from the traditional hard protection to the ecological structure. In recent years, in slope protection above the normal water level, a porous precast concrete ecological brick structure is generally adopted. The structure can achieve the effect of protecting the stability of the bank slope through the counterweight of the concrete structure, and can be used for planting plants due to the vertical holes, so that the green landscape effect of the engineering area is increased, and the influence of the engineering implementation on the local ecological environment is reduced.

Therefore, the ecological property of the porous ecological brick is mainly reflected by the growth effect of the green plants with the holes. One of the main ways to increase the ecological performance of the structure is to increase the single-pore size of the ecological brick to provide more sufficient growth space for plants. Therefore, the ecological brick with large volume and large porosity can provide a better growing environment for plant roots because more planting soil can be contained, and becomes a development trend in the practice of bank slope protection engineering.

However, since the overall prefabricated massive monolithic structure is heavy in weight, it is easy to construct it on flat ground where mechanized construction can be used. When the method is applied to a slope with a slope, a construction grid ridge with limited width and a region with lower mechanized construction level, the construction becomes more difficult. Under the circumstances, in order to comprehensively consider the ecological effect and the construction convenience of the side slope protection structure, an assembly for protecting the water side slope and an assembled large-volume ecological side slope protection structure adopting the assembly need to be provided.

The utility model discloses a solve another technical scheme that technical problem that exists among the known art adopted is: an assembled large-volume ecological water side slope protection structure adopting the large sash protection units is provided with at least one stage of protection structure, each stage of protection structure is arranged on a slope surface of a corresponding stage, the top and the bottom of each stage of slope surface are respectively provided with a sash ridge, each stage of protection structure is arranged between two sash ridges, a plurality of large sash protection units are arranged, and the large sash protection units are formed by splicing the corner connecting blocks and the prefabricated rod pieces; and a ploughing and planting soil body is filled in the large sash protection unit, and green plants are planted on the ploughing and planting soil body.

And a shielding layer is arranged on the surface of the plowing and planting soil body.

The shielding layer is a straw rope layer or a stone layer or a geogrid.

The utility model has the advantages and positive effects that: compared with the integral prefabricated large sash protection structure with the same size, under the same condition, the soil containing amount, the water and soil conservation condition and the plant growth condition are consistent. Because big sash protection unit adopts components of a whole that can function independently tenon fourth of twelve earthly branches grafting structure, single component light in weight is convenient for remove in the work progress and is put and lay, and then is convenient for construct, under the condition that can't realize mechanized construction, the effect is especially showing. The local damage is easy to maintain. To sum up, the utility model discloses the bulky advantage of current whole prefabricated formula bulky ecological protection structure has been remain to overcome the big shortcoming of whole prefabricated formula bulky ecological protection structure weight, the engineering of inconvenient mechanized construction among the specially adapted inland river channel construction.
