Abstract
The invention provides a permeable overflow dam combining functions of water level control and water purification, which comprises a solid dam body, a permeable dam body and water purifying media arranged in the permeable dam body, wherein the solid dam body is in a water-proof solid structure formed by casting concrete or reinforced concrete, and the height of the dam top of the solid dam body is the height of a higher water level in the lowest water level required by a river channel ecological system or the lowest water level required by river channel landscape environment; the permeable dam body is a lattice fence formed by casting concrete or reinforced concrete, a plurality of reinforced concrete partition walls are cast in the permeable dam body along a river width direction, a plurality of no-fines concrete walls are cast in the permeable dam body along a water flow direction, and the height of the dam top of the permeable dam body is higher than the designed normal water level of the overflow dam and is lower than that of the designed flood level of a river channel; and the water purifying media are pebbles, vermiculites, zeolites or spherical water purifying fillers. The invention not only can meet the requirement of raising the water level without influencing the flood discharge capacity but also can effectively purify water and improve river water environment quality.
Description
Technical field
The present invention relates to a kind of water level control and the compound permeable overfall dam facility of water quality purification function, particularly pollutant in the river water body is had the permeable overfall dam of holding back clean-up effect.
Background technology
Before the present invention, existing overfall dam is mainly the retaining that (reinforcing bar) concrete or stone masonry building forms or the entity dam of heading up, main effect is by interception upland water and savings or heading up, satisfy the requirement of aspects such as irrigation, water supply, landscape environment, when flood arrives, the overflow and draining downstream from the dam of a large amount of floods is a kind of typical hydraulic engineering.The type overfall dam is very remarkable to adjusting of the river water yield and heading up effect, but absorption of the pollutant in the water body and crown_interception are not almost had, and its ability that purifies the river water pollutant is also very limited.
And also do not have at present a kind of overfall dam both to possess the water conservancy functional requirement of water level control, can have purifying water again, improve the ecological functions requirement of water environment.The design of the permeable overfall dam that this novel water level control and water quality purification function are compound and structural system and application example all do not have discovery in the document at home and abroad.
Summary of the invention
Purpose of the present invention is exactly the transformation that is by to the overfall dam dam structure, make improved dam body not only can have the hydraulic engineering function that the water yield is regulated and water level is controlled of current overfall dam, also possess the ecological engineering function of holding back with the purifying water body pollutant simultaneously, become a kind of novel water level control and the compound permeable overfall dam of water quality purification function.
Technical scheme of the present invention is: the compound permeable overfall dam of water level control and water quality purification function comprises solid dam body, permeable dam body and is arranged at the interior water purification medium of permeable dam body; Solid dam body is that concrete or steel concrete are built the waterproof solid construction that forms, and the dam crest height of solid dam body is the height of the higher level among both of the lowest water level of river channel ecology system requirements or the lowest water level that requires for the river course landscape environment; Described permeable dam body is the sash enclosure wall that concrete or steel bar concrete casting become, in the permeable dam body along the river cross direction pour into a mould the steel concrete partition wall that several spaces are 4m, and pour into a mould the non-fine concrete wall that several spaces are 2m along water (flow) direction, the dam crest height of permeable dam body surpasses overfall dam design ordinary water level height, but is lower than river course design flood level height; Described water purification medium is that particle diameter is cobble, vermiculite, zeolite or the spherical Filler for water purification of 10～20cm; Has the biological biomembrane that forms of microorganism and rotifers on the described water purification medium.The upstream face place of described permeable dam body and back side place are equipped with interception iron wire filter screen, and its mesh aperture is 1～5cm.
The invention has the advantages that: overfall dam bottom solid dam body portion can guarantee that dry season, upper river was kept certain water level, satisfies the lowest water level of overfall dam upstream ecosystem safety or the lowest water level that landscape function requires.The permeable dike body portion on solid dam body top can be held back effectively, filters and purify by water body, by the biomembrane that the purification medium surface is adhered to, the water quality of infiltration is improved.When the river course comes the water yield big, water body can be from the overflow of overfall dam top, can not influence the flood passage function in river course, the sluicing effect of flood simultaneously can also be removed the silting of permeable dam body inside, and upgrades Filler for water purification surface biological film and activate its clean dirty function.Therefore, advantage of the present invention is the requirement of both having satisfied heading up and not influenced the flood passage function, can purify water effectively again, improves the river water environmental quality.

The specific embodiment
Embodiment
After moulding of the present invention, solid dam body 1 part in overfall dam bottom can guarantee that dry season, upper river was kept certain water level, satisfies the lowest water level of overfall dam upstream ecosystem safety or the lowest water level that landscape function requires.Permeable dam body 4 parts on solid dam body 1 top can be held back effectively, filter and purify by water body, by the biomembrane that purification medium 5 surfaces are adhered to, the water quality of infiltration are improved.When the river course comes the water yield big, water body can be from the overflow of overfall dam top, can not influence the flood passage function in river course, the sluicing effect of flood simultaneously can also be removed the silting of permeable dam body 4 inside, and upgrades Filler for water purification surface biological film and activate its clean dirty function.After flood period, water purification medium 5 surfaces are enriched biological and form biomembrane again, upgrades and has activated water purification medium 5 surface biological films and clean dirty function thereof, has recovered the purification of water quality ability of this permeable overfall dam again.
In addition,, can set up a plurality of overfall dams to guarantee under the situation of river channel ecology water level, use water level control and the compound permeable overfall dam of water quality purification function for mountain stream type river course, then better to the clean-up effect of river water.
