Research On The Urban Planning Countermeasures Of Urban Waterlogging In Harbin

Our cities are increasingly serious waterlogging problems, not only wide spread range, the number of frequent occurrence, and the resulting losses, caused great impact on urban safety. In countries proposed to develop urban infrastructure construction, improve the urban drainage waterlogging system, construction of the city's comprehensive pipe gallery, and focus on building background sponge under the city, this paper takes Harbin specific object of study of urban waterlogging disaster prevention planning strategy research.Firstly, the basic theory literature review will study in depth the basis for the issue; secondly by domestic and foreign urban waterlogging prevention, rainwater recycling and other related cases to collect and summarize, sum up the city from real cases waterlogging disaster prevention and management research experience, based topics provide realistic basis and practical support; followed by field research in Harbin, urban waterlogging collect relevant information, the imp act of position on Harbin waterlogging occurs, the time to produce, triggering secondary Health hazards typical water logging points and detailed investigation of the case, in-depth understanding of the basic overview of waterlogging and urban construction and urban planning in the existing problems.This article summarizes the Harbin waterlogging disaster presented on time, feature space, the relationship between rainfall, typical waterlogging point, and in accordance with the urban water cycle "precipitat ion-catchment-drain" process, the actual situation at Harbin Discussion the formation mechanism of waterlogging disasters, analysis results in waterlogging disaster planning by water shortage, improper catchment, drainage caused by unfavorable comprehensiv e, summed up the city rainfall, the city water system, city underlying surface topography in urban areas, urban road system the main factors, urban facilities and urban stormwater drainage facilities to waterlogging disasters.According to the above factors, reference the urban water cycle "precipitationcatchment-drain" process, from the city's water catchment, drainage planning countermeasures proposed three angles waterlogging disasters. Strengthened through urban green spaces, squares and other public spaces in the design of urban water, through the combination of the layout of urban land use planning and urban road traffic planning and reasonable catchment, integrated control waterlogging from many angles.
