Referring to fig. 1-2, the embodiment of the present invention provides an ecological reinforcing structure for river bank protection, which includes a reinforcing wall 9, a protection leg 6 and a planting structure. The utility model discloses in, be the outside for one side that is close to the river course, correspondingly, one side that is close to the river bank then is the inboard. The reinforcing wall body 9 is fixed on the outer side of the original bank wall 10, so that the structural stability of the original bank wall 10 is enhanced, and the original bank wall 10 is beautified. In some embodiments, the outer side of the original quay wall 10 is provided with a quay wall step, and the reinforcing wall 9 is fixed on the shoulder surface of the quay wall step of the original quay wall 10. Furthermore, the inner side of the reinforcing wall body 9 is provided with a step part, and the shoulder surface of the step part is used for being connected with the top surface of the original shore wall, so that the reinforcing wall body 9 and the original shore wall 10 can be connected in a mutual clinging manner, and the integrity between the reinforcing wall body 9 and the original shore wall 10 is enhanced. Optionally, the reinforced wall 9 is an outer lining reinforced concrete surface layer, and the structure is stable and reliable.

The inboard of planting structure meets with reinforcing wall body 9, and reinforcing wall body 9 plays the supporting role to the planting structure. Planting structure includes dry masonry layer 7 and anti-filter body, and dry masonry layer 7 sets up on the top surface of banket 6, and anti-filter body sets up on the top surface of dry masonry layer 7. The dry masonry layer 7 is used for supporting the inverse filter body and filtering river water preliminarily, the river water upwards permeates into the inverse filter body through the dry masonry layer 7, the inverse filter body filters the river water to a certain degree, and the filtered river water can ensure the good growth of the aquatic plants 12 due to the fact that the aquatic plants 12 which are cultivated in a soilless mode can be planted in the inverse filter body. Furthermore, a planting soil layer 1 is paved on the top surface of the inverted filter body to plant aquatic plants 12 needing soil cultivation.
In some embodiments, the planting structure further comprises a barrier 8, the barrier 8 being disposed on the top surface of the dry masonry layer 7, the anti-filter being located between the barrier 8 and the reinforced wall 9. Optionally, the reverse filter is located partially or completely between the barrier 8 and the reinforcing wall 9. When the river is higher than the daily low water level 13, the blocking body 8 plays a role in blocking the reverse filter body and the planting soil layer 1 and avoiding the loss of the reverse filter body and the planting soil layer 1, so that the height of the blocking body 8 is higher than or equal to the daily high water level 14 of the river. As an alternative embodiment, the blocking body 8 is a long concrete block, and the length direction of the concrete block extends along the flow direction of the river channel, so as to completely isolate the river water from flowing into the reverse filter and the planting soil layer 1 beyond the blocking body 8, ensure that the reverse filter and the planting soil layer 1 cannot run off from the side, and keep the humidity of the reverse filter and the planting soil layer 1 low. As another alternative, the barriers 8 comprise gabions, which likewise extend in the direction of flow of the river, and which both act to isolate the drainage of the inverted filter and the planting soil 1 and also to allow the river water to flow through them laterally into the inverted filter volume planting soil 1, keeping the inverted filter and the planting soil 1 in a high humidity environment.
In some embodiments, the reverse filter body comprises a medium-coarse sand layer 2, a geotextile 3, a melon and rice stone layer 4 and a gravel layer 5 which are sequentially stacked from top to bottom. Optionally, the crushed stones in the crushed stone layer 5 have a particle size of about 20 mm. Further, when keeping off body 8 and including the gabion, because the footpath of melon and rice stone layer 4 and metalling 5 is all less, cross the gabion easily along with river water and run off the river course, for avoiding the loss of anti-filter body composition, be equipped with the recess on the top surface on dry masonry layer 7, form the accommodation space between recess and the lateral surface of consolidating wall body 9, melon and rice stone layer 4 and metalling 5 are located the accommodation space. Gravel layer 5 and melon and rice stone layer 4 are laid in proper order in the accommodation space, and the top surface on melon and rice stone layer 4 flushes with the top surface on dry masonry layer 7, then is paved with geotechnological cloth 3, prevents that rubble and melon and rice stone from getting into under the drive of river that coarse sand layer 2 is lost through the gabion. Because the rubble layer 5 and the melon and rice stone layer 4 are both located in the accommodation space, the anti-filter part is located in the accommodation space, and the rest part is located between the reinforcing wall 9 and the baffle 8.
In some embodiments, a hydrophilic platform 11 is further disposed on the top surface of the reinforced wall 9, and the hydrophilic platform 11 extends in an inward direction. As the outer side of the reinforced wall body 9 is provided with the planting structure for planting the aquatic plants 12, the planting structure can also be used as a platform for lifesaving when falling into water, and the hydrophilic platform 11 is beneficial to people to approach the river bank and simultaneously ensures the safety.
Referring to fig. 1, the following reconstruction project for raising the original quay wall 10 is taken as an example, and the construction steps are as follows:
s10, constructing a protection leg 6 on the outer side of the original quay wall 10, wherein the top surface of the protection leg 6 is slightly higher than or equal to the daily low water level 13;
