Technical field

The present invention relates to hydraulic engineering gate technical field, specially a kind of pointer type opens and closes hollow steel lock with disc spins Door.

Background technique

Water is the soul in city, has waterside town city just to have " raw breath ", river water environment is occupied important in people mind Status.Urban river becomes water head site, power source, communications and transportation channel, has resource, environment, ecology, landscape, culture etc. more The major function of aspect.But with the progress of society and economic development, river ecosystem is damaged in function and structure, The reduction of River Ecosystem Functions also results in urban water shortage and image is destroyed and constrains the development in city to a certain extent.City City's hydraulic engineering combination urban environment, landscape, ecological construction, have become the trend of water development.In recent years, domestic and international city River improvement thinking was focused on merely flood control, water supply function by the past, gradually under the premise of guaranteeing flood control, water supply security, was weighed Depending on river ecosystem restoration, waterfront landscape construction, the transformation of Urban Water-culture constructive direction.

The research foreign countries of City River Harnessing have quite long history, Japan and the United States, moral, Switzerland since the 1980s The City River Harnessing of equal developed countries starts to turn to urban river comprehensive treatment and ecological construction, has entered " ecological engineering The advanced stage of improvement " and " near-nature forest river improvement ".The important feature of urban river comprehensive treatment and ecological construction is to abandon Rapid economic development period is formed by the river improvement idea of " only efficiency doctrine ", respects the natural law of river system, note The recovery and protection of weight river natural ecology and natural environment, give full play to the comprehensive service function in river.The 1990s Urban river comprehensive treatment and ecological construction tend to prosperity state.With Tokyo, the construction of Yokohama water front and U.S. Ba Er Rub the water front development that inner harbor construction is representative, fundamentally changes the image of Water Space, has restored its vigor again. The hydrophilic construction of park of the planning of Washington Potomac greenbelt and Japanese various regions, reappearing urban river, river water is clear, greenery Lined good natural character.South Korea started to repair the work in clean brook river in 2004, and engineering terminates within 2005.Commencement of works Before, by widely publicizing, so that citizen understood project profile, understood inconvenience caused by engineering construction lives to it, to make work Journey construction obtains the extensive masses and participates in and support.The engineering is built by waters landscape and aqueous culture, greatly improves Soul International image, obtain good Social benefit and economic benefit.

China's City River Harnessing is started late, and administering method mainly has physics improvement and ecological management.Zhu Jiwei, Liu Jian Woods etc. thinks that river and urban economy development, cultural continuity, social harmony are closely bound up.The comprehensive treatment of urban river is one System engineering should be administered by ecology synthesis, biometric safeguard diversity, pass on River Hydrology, establish hydrophilic theory, build people With the water environment of natural harmony.Wang Shuyan, Wang Jun, Han Zi advise the element to " river ecologicalization regulation " to be analyzed, it is believed that River ecologicalization regulation is based on ecology, urban ecology, environmental science, urban ecological planning scheduling theory, to river The transformation for facilitate economic, the social structure mutually coordinated with natural ecological environment, facility, function, landscape etc., is repaired The ecological functions in river combine Urban House, traffic, infrastructure and process of consumption and natural ecosystems together, are city City resident provides suitable living environment, promotes River valley economy development, and reduces environment negative effect to greatest extent, promotes river Ecosystem Service, promote Environment-friendly city and Ecological Civilization Construction to focus on river during ecology is renovated latent In the exploitation of hydrophile function and service function, good person and water, people and the relationship in river are handled.Dong Zheren, Sun Dongya, Peng Jing are proposed River ecosystem restoration overall model has systematically discussed hydraulic engineering to river ecosystem stress and its mechanism, to traditional sense On Water Conservancy Works theory and method carried out the self-examination of system, summarize river ecosystem restoration planning principles and comment Estimate method and river corridor ecological reestablishment.And propose that the task of River ecological recovery there are three sports: first is that water quality item The improvement of part, hydrologic condition；Second is that the improvement of river morphology character；Third is that the recovery of biological species, catalogue is to improve river The structure and function of the ecosystem, outstanding feature are the multifarious raisings of biocoene.He Yongheng, Fang Yanqin think River Landscape Following measures can also be used in planning: (1) general plotting of greenery patches Wa- ter environment should expand greenery patches along the river, shape as far as possible along the river At more continuity greenbelt, the profile in ancient city is delineated with green, is continued city context, is embodied the new shape of modern city As；(2) Ba Zha is combined, and extends the water surface along the river.Planning river can build colorful rubber dam, and pump house appearance can be by scenic spot house mark Quasi- design, the major function of rubber dam are to increase impounded area, to form the water surface, form man-made lake beautiful scenery；(3) ecological bank protection can The ecological engineerings bank protections such as nature soil bank slope, natural gentle slope, tree planting, grass planting are taken in planning, not only prevent erosion, but also are aquatic The growth of plant, the breeding of aquatic animal, the procreation activity of inhabiting of amphibian create conditions；(4) green tree species and flowers and plants edge River green tree species, using shrub and flowers and plants as main vegetation, form multiple types, multi-level ecological community using arbor as Key species.

Although China starts late in terms of river improvement, some trials had also been made in recent years and all achieved certain Effect.Sichuan Chengdu Fu Nan River park is the ecological environment protection park being the theme with the regulation of water, the water being contaminated from Fu Nan River extraction comes up, and carries out natural ecology purified treatment by the artificial wet land system in park, eventually becomes the work of " up to standard " Water returns river.The intention in the park is proposed by American scholar Mrs Bei Dameng, obtains the support of Chengdu municipal government, rear group In knitting, beauty, the water conservancy of Han Sanguo, urban construction, environmental protection, gardens and artist's Joint Designing form, 21 generation that in October, 2000 holds Discipline urban construction and the world conference of environment Chengdu, give abundant affirmation to the improvement of Chengdu Fu Nan River, which obtains People from world occupies prize etc. three international Grand Prixs.The success of Fu Nan River harnessing project, contain urban sustainable development, urban construction with Environment, house and various intensions such as live in peace, are the successful examples of City River Harnessing.Pekinese turns river, cold water river and passes through Ecoscape construction, reproduces the Wa- ter environment that water is clear, bank is green.The moat in Hefei passes through the transformation and construction of many years, nowadays shape At the annular scenic spot that mountain villa etc. forms is clapped by carefree saliva, Baohe Park, milky way park, the fish fry pool, glass, become down town The daily Open style park having a rest of area citizen, also makes Hefei City obtain the good reputation of garden-like cities.In taking the lead in entering as China Deng flourishing horizontal Shanghai City, also put forth effort the spirit for embodying " people-oriented ", building security of furnishing a huge amount of money for, comfortable, graceful city Landscape Water System.Guangzhou oneself proposed Guangzhou Section of Pearl River build as French Seine Paris section it is beautiful Control target specifically includes the flood control standard for improving dyke, improves traffic, the greening environment of two sides, especially beautification river two Bank allows tourist and citizen to have the good place to go an of sightseeing, amusement；It is horizontal to maintain three vertical three in urban development construction for Suzhou City Add the river network of a ring and the waterside town characteristic of small bridge over the flowing stream, maintains the parallel basic configuration in road river and landscape, urban renewal Achieve good effect.Once " why Suzhou became the key in Suzhou to famous foreign citizen of Chinese origin architect Leon Ming Pei in evaluation Suzhou in this way Be water, building or next ".Also city has been carried out in succession in other big and medium-sized cities such as Shenyang, Harbin, Taiyuan, Tianjin etc. City's river corridor restoration and Landscape rebuilding work etc..

For City River Harnessing both domestic and external still in the exploratory stage, many work, which are still conceived to, repairs river in a certain respect Function, such as foreign countries are while taking into account landscape, and the work of more stress restoration of the ecosystem and rebuild etc. is domestic then more consider Landscape construction, there are also to be strengthened for restoration of the ecosystem work.But river construction and socio-economic development, area, warp are not comprehensively considered The relationship of Ji, water resource, tourism, citizen requirement, culture etc., City River Harnessing lack the theoretical direction of system.
