Ecological water retaining dam

Abstract

The invention discloses an ecological water retaining dam. The whole dam body comprises three parts, i.e. an earth-rock dam body, a timber pile reinforcing structure and an isolating bamboo raft, wherein the earth-rock dam body is in a dual-layer structure; the inner layer is filled with bagged clay; the outer layer is filled with bagged gravel; the timber pile reinforcing structure is used for ensuring the safety and the stability of the dam body; and the isolating bamboo raft is used for reinforcing and isolating turbulence. Due to the adoption of natural material, the ecological water retaining dam disclosed by the invention has the advantages of stable structure, convenience in dismantlement and construction, and having the function of intercepting a water body, water conservation function for controlling the water level, and certain functions of purifying the water quality and repairing ecology as well as a landscape effect; and the ecological water retaining dam is suitable for construction of temporary water dams, short-term use of water dams or water retaining dams for middle and small creeks in river network regions and belongs to the fields of river pollution treatment and environment protection.

Description

(1) Technical field: [0001] The invention relates to a technology for river environment treatment, more specifically an ecological dam. (two) background technology: [0002] In the environmental management of rivers, temporary interception or blockage measures are often used for environmental protection dredging or river embankment construction. The interception method used is mainly to build temporary dams, which is also a method often used in construction. However, temporary dams are mostly piled with bagged soil or clay or construction waste materials. Their structural safety has not attracted everyone's attention, and their appearance is very unsightly. It not only affects the surrounding environment of the construction area, but also has no purification ability for water bodies. Not to mention the restoration of ecological functions. Especially in the river network area, there will be such a situation where temporary dams also take into account pedestrian passages. Som...

Problems solved by technology

[0003] At present, Tian Meng and others from the Nanjing Institute of Environmental Science of the Ministry of Environmental Protection have disclosed "an ecological permeable dam". Purification effect; Tu Yanli from the Institute of Plateau Biology of the Tibet Autonomous Region has disclosed "a kind of dam" for wetland protection and restoration. The dam has a water biological culvert channel, which establishes the biological connection between the upstream and downstream of the dam, avoiding the ecological problems of the water area. The fragmentation of the environment, these are the work carried out in the direction of the organic combination of the water conservancy function of the dam, pollution purification, ecological protection, etc., and the ecological barrier with interception of water body, stable structure, water purification, beautification of the environment and certain ecological functions There is no precedent for the report and application of dams in my country
