Artificial floating island suitable for bottom surface of hard riverway and preparation method thereof

Abstract

The invention provides an artificial floating island suitable for the bottom surface of a hard riverway and a preparation method of the artificial floating island. The artificial floating island comprises a central bracket, a floating core, a sediment chamber and a hollow mesh enclosure from inside to outside, the floating core, the sediment chamber and the hollow mesh enclosure form a floating island main body; the central bracket comprises a planting pool, a rod body and an anchoring disc from top to bottom; the floating core comprises an outer box and a floating material filled in the outer box, and the filling material is composed of biochar, activated carbon, floating foam and floating ceramsite according to a certain proportion; the sediment chamber is provided with a plurality of chamber units; and the area of a grid unit of the hollow mesh enclosure is smaller than that of the sediment chamber units. The method comprises the following steps: establishing an artificial floating island, and creating an aquatic environment; forming an autonomously circulating small ecological system gradually by achieving the process goals of sediment retention, animal habitat building, different water layer plant growth and the like, wherein the system is suitable for the river channel environment with the hardened bottom face.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to an artificial floating island suitable for the bottom surface of a hard channel and a preparation method thereof. Background technique [0002] In the urban standardization construction, the hardening of the river has been an important part of it for a long time. The hardening of the river channel is mostly aimed at the revetment of the river channel, but in some areas, the revetment and the bottom surface of the river channel are all hardened in all directions. However, for the ecological environment, the all-round hardening of river channels brings many problems, such as blocking groundwater recharge, loss of self-purification capacity of river water, loss of revetment water storage capacity, cutting off biological exchanges at the junction of water and land, reduction of river biodiversity, and disappearance of natural river landscapes. Wait. There...

Problems solved by technology

As far as its use environment is concerned, it mostly floats on the surface of the water body, and it is difficult to go deep underwater for all-round ecological restoration.

In terms of its functions, it mostly focuses on the presentation of individual plant landscapes, simple water purification, aquaculture, etc., unilaterally relies on the construction of floating island devices, and seldom designs and thinks from the entire river ecosystem, and its use has increased over time And the problem is frequent
