Embodiment Construction

[0019] Below in conjunction with embodiment the present invention will be further described.

[0020] A method for ecological restoration of river bank slopes, comprising the following steps,

[0021] (1) River bank slope adjustment;

[0022] Cut the slope and reduce the load on the bank slope of the river, keep the slope between 30° and 60°, and clean and level the slope; Arrange several anchor rods evenly and fixedly downwards, and the metal mesh is connected and fixed with the anchor rods through thin iron wires; the distance between adjacent anchor rods is 0.5m; the metal mesh is as close as possible to the slope, if there is a gap between the metal mesh and the slope , fill it with soil.

[0023] (2) plant mat preparation;

[0024] The selected plant seeds are sandwiched between two layers of wood pulp paper, and then attached to the inner side of the ecological bag. The wood pulp paper and the inner side of the ecological bag are fixed by sewing or gluing; the ecologi...

Abstract

The invention discloses an ecological restoration method for a river bank slope. The method comprises the following steps that (1) slope cutting and load reducing are performed on the river bank slope, wherein the gradient of a slope surface is kept in the range of 30-60 degrees; the slope surface of the bank slope is provided with a metal net, a plurality of anchor rods are uniformly fixed on thetop edge of the slope and along the slope from top to bottom, and the metal net is fixedly connected with the anchor rods through iron wires; (2) selected plant seeds are clamped between two layers of wood pulp paper and then attached to the inner side of an ecological bag, the wood pulp paper is fixed to the inner side of the ecological bag through sewing or gluing; the ecological bag is filledwith a loam-like matrix mixture, and then the pocket mouth is sealed; (3) plant mats are neatly laid on the metal net and fixed on the slope surface through ground anchors, and the joints of every twoadjacent plant mats overlap with 5-10cm; (4) regular maintenance is performed, wherein watering and fertilizing are performed. The ecological restoration method for the river bank slop has the advantages that the stability of the slope bodies and conservation of water and soil at the two sides of a riverway can be achieved, the environment is effectively improved, and greening and appearance of urban landscape are improved.

Description

technical field [0001] The invention relates to a method for ecological restoration of river bank slopes, and belongs to the technical field of river regulation. Background technique [0002] At present, in order to prevent the water flow from scouring and eroding the bank, the damage of the ship wave to the bank, and the rain to the bank, and to maintain the stability of the bank, most of the traditional revetment structures such as mortar masonry or dry stone revetment are used, and alloy steel wire cages are filled with gravel. Or pebble layer and other structures. Not only the investment is large, the construction is difficult, but also the way of ecological cycle is isolated, it is not an ecological river revetment, and it has a large contrast with the surrounding landscape, which is not conducive to the establishment and restoration of the river ecosystem. Contents of the invention [0003] Objective: In order to overcome the deficiencies in the prior art, the prese...
