Description

Ecological slope protection facilitating drainage

Technical Field

The utility model belongs to the technical field of the bank protection engineering, in particular to do benefit to ecological bank protection of drainage.

Background

The ecological slope protection for river channel is to support slope or side slope with the basic knowledge of comprehensive engineering mechanics, soil science, ecology, botany and other subjects. River course bank protection is mainly in order to prevent soil erosion and water loss, prevents the destruction of rainwash or water impact to the river bank.

The slope protection structure commonly used at present is paved by adopting building blocks, for example, CN110725278A provides a novel river channel ecological slope protection structure, which comprises ecological building blocks and anchoring nails, wherein two ecological building blocks which are adjacent up and down or adjacent left and right are fixedly connected through the anchoring nails; the anchor nail has improved joint strength and stability between two adjacent ecological building blocks about or about from top to bottom greatly, and then improves whole ecological slope protection structure's stability, improves slope protection structure's protecting effect, prevents to cause the water and soil loss of river channel slope protection face.

Through analysis discovery, building block and vegetation can protect the bank protection, reduce soil erosion and water loss, but the security of bank protection itself is not high, and especially when the abundant season of rainfall, the drainage ability of bank protection is limited, structural stability is not high, and the rainwater can erode the earth of planting the plant, leads to the bank protection to subside.

At present, concrete is generally adopted for fixing among the state building blocks, but because the corrosion resistance of the concrete is poor, the effect of fixing is difficult to play under long-time erosion, and particularly, in seasons with a lot of rainwater, the ecological building blocks are likely to be directly washed away by river water, so that water and soil loss of a river channel is caused, and dike can be caused seriously.

Drawings

The invention will be further explained with reference to the following figures and examples:

FIG. 1 is a cross-sectional view of the present invention;

FIG. 2 is a distribution diagram of the drainage channel of the present invention;

in the figure: slope body 1, retaining wall 2, canopy 3, horizontal water drainage tank 4, vertical water drainage tank 5, grass planting brick 6, connecting pipe 7, drain pipe 8, water catch bowl 9, grid net 10, anchor rod 11, geotechnological cloth 12.

Detailed Description

As shown in fig. 1~2, an do benefit to ecological bank protection of drainage, including slope body 1, 1 bottom and the top of slope body are equipped with retaining wall 2 and canopy 3 respectively, and canopy 3 is for pouring concrete block, and retaining wall 2 is the interior rubble of packing of gabion net, and is specific, retaining wall 2 can be for being the gabion that the ladder piles up the setting, through piling up and crisscross improvement stability. The slope body 1 is gone up along domatic horizontal water drainage tank 4 and the vertical water drainage tank 5 that is equipped with mutual intercommunication, horizontal water drainage tank 4 and vertical water drainage tank 5 divide the slope body 1 into a plurality of unit areas, the grass planting brick 6 is laid on the unit area surface, grass planting brick 6 is laid and is protected domaticly, form the planting groove simultaneously, conveniently plant the vegetation, horizontal water drainage tank 4 bottom is equipped with a plurality of wash ports, the wash port passes through connecting pipe 7 and the pre-buried drain pipe 8 intercommunication in the slope body 1, 8 tip of drain pipe wear out retaining wall 2.
