Base substance replacement type ecological filter dam

Abstract

The invention relates to a base substance replacement type ecological filter dam. The dam comprises an upstream filter dam body and a downstream filter dam body. A material padding space is formed between the upstream filter dam body and the downstream filter dam body. A mental material padding frame is arranged in the material padding space. A stereo elastic multi-hole material padding ball is arranged in the mental material padding frame. The material padding ball is filled with a base substance padding material. The upstream filter dam body and the downstream filter dam body is composed of a surface layer and an inner layer, wherein the surface layer is formed by the stone, and the inner layer, located under the surface layer, is made from gravel, zeolite and a compound mixed with iron slag and like. A first filter dam base pile and a second filter dam base pile are arranged at two sides of the bottoms of the upstream filter dam body and the downstream filter dam body. A connected bedding, paved from reinforced concrete, is formed between the first filter dam base pile and the second filter dam base pile. The upstream filter dam body and the downstream filter dam body are constructed on the bedding. The base substance replacement type ecological filter dam is novel and unique in structure, easy to constructing, low in cost, good in using effect, non-blocking phenomenon, and long in service life, so that ecological and environmental protection of the rivers is conducted effectively, and social and economical benefits are great.

Description

technical field [0001] The invention relates to river environmental protection equipment, in particular to a matrix replacement ecological filter dam. Background technique [0002] With the rapid development of my country's economy, the consumption of water resources has increased, and the water environment has also been seriously polluted. In the north of my country, the river water environment is seriously polluted, the self-purification ability of the river water body is lost, and the river water ecosystem is destroyed. River management and restoration (restoration) of the water ecosystem are urgent needs for current social development and the construction of water ecological civilization. [0003] Ecological filter dam, also known as permeable dam, filter dam, etc., is a kind of river ecological purification and restoration technology developed by combining the principle of constructed wetland and rapid infiltration. It uses gravel, pebbles, The dam built in the river c...
