Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses novel ecological bank protection of water conservancy.

Referring to fig. 1, a novel ecological bank protection of water conservancy, including the soil matrix 1 of river bank both sides side slope to and set up at soil matrix 1 and be close to the slope protection main part 2 on the river is domatic, slope protection main part 2 is including banket 21, banket 21 sets up in the bottom of soil matrix 1, banket 21 can choose for use and throw the stone, heavy pillow, heavy row etc. select in this embodiment and use the concrete block, banket 21 of concrete block is difficult to be removed by rivers erode, can prevent that rivers from elutriating soil matrix 1, it is more firm to make the bank protection.

The slope protection main body 2 further comprises a drainage channel 22 made of reinforced concrete, the drainage channel 22 comprises a plurality of longitudinal drainage channels 221 and a plurality of transverse drainage channels 222 which are arranged on the soil foundation 1, the longitudinal drainage channels 221 are arranged along the slope surface direction of the slope protection main body 2 at equal intervals, the transverse drainage channels 222 are arranged at equal intervals and communicated with the adjacent longitudinal drainage channels 221, the soil foundation 1 is tamped by the longitudinal drainage channels 221 and the transverse drainage channels 222, and a net-shaped protection structure is formed on the soil foundation 1.

Meanwhile, the plant groove 23 is provided on the soil base 1 between the longitudinal drainage channel 221 and the transverse drainage channel 222, and the plant 231 with developed roots, such as poa annua, festuca arundinacea, etc., is planted in the plant groove 23, and can play a role of anchoring soil of the soil base 1, so that the plant 231 can be stably rooted in the plant groove 23 at the initial stage of planting, referring to fig. 2 and 3, the plant groove 23 is laid with the mud blocking net 232, the mud blocking net 232 can wrap the root of the plant 231 in the plant groove 23, and the plant 231 is fixed in the plant groove 23 in a sheet manner, so that the adhesion stability of soil in the plant groove 23 is improved, and the slope protection main body 2 formed by the drainage channel 22 and the plant groove 23 at intervals can reduce soil erosion and water loss of the soil base 1 caused by rain water and river water erosion.

Because the waves generated by the water level change of the river can impact the revetment, in order to reduce the influence of the impact on the plants 231 planted on the plant grooves 23, the revetment main body 2 is further provided with a soil protection member 24, the soil protection member 24 is fixed at the bottom of each plant groove 23, one end of the soil protection member 24 horizontally extends into the soil foundation 1, the other end of the soil protection member extends out towards the plant groove 23 and vertically extends upwards to a position half of the height of the plant groove 23, when the river water rushes to the revetment main body 2, the soil protection member 24 can buffer the force of the river water impacting on the plant groove 23, the river water on the periphery of the plants 231 is relatively smooth, the condition that the plants 231 are loosened and separated due to the fact that the river water directly scours the roots of the plants 231 is reduced, the plants 231 are more firmly rooted on the plant groove 23, and the water and soil loss of the revetment is effectively reduced.

In addition, as shown in fig. 3, the top end of the soil protection member 24 is provided with a buffer surface 242, and the buffer surface 242 is inclined toward the river surface, so that water splash caused when the river water strikes and beats the soil protection member 24 is reduced, and the influence of the river water on the plants 231 is further reduced.
