Description

Modularized ecological revetment

Technical Field

The utility model relates to an ecological revetment, in particular to ecological revetment of modularization.

Background

With the economic development and urbanization progress, the consumption of water resources is increasing day by day, thereby causing the shortage of water resources and the serious problem of water pollution. In addition, due to the advance of the urbanization process, the reconstruction of rivers and lakes is more and more, and the reconstruction of rivers and lakes brings huge use functions and economic benefits, and meanwhile, the ecological system is seriously damaged, so that the planning of sustainable development is not facilitated.

At present, measures such as enlarging or compressing the river width, cutting a curve to straighten, dredging and digging a riverbed, building a bank protection project and the like are generally adopted for treating riverways and lakes, so that flood control and other effects are improved. However, the implementation of the above engineering can also cause changes of original river terrain sections, vegetation structures, biological environments, water level conditions and the like, thereby causing the ecological environment of the river to be affected.

In order to eliminate or reduce the influence on the ecological environment and reduce the pollution caused by the combined discharge of rain and sewage into rivers and lakes, the construction of enlarging river revetments is a common way, but the traditional river revetments mostly adopt concrete, stones and cement as main materials to be directly paved, so that nitrogen and phosphorus in urban rain and sewage are easily caused to enter rivers and lakes to cause eutrophication and reduce self-purification capacity. Therefore, the ecological revetment construction which can meet the flood control requirement, can also take ecological treatment and water filtration into consideration and achieve good landscape effect becomes the first choice of the urban river revetment construction.
