Description
Technical field
The invention belongs to the fields such as urban transportation and hydraulic engineering, and in particular to a kind of new road for slowing down urban waterlogging
Structural shape and its method of construction.
Background technique
With the fast development of China's economic society and the continuous acceleration of urbanization process, the coverage rate of urban road is also got over
Come higher, the main cities path area of current developed country accounts for about the 20% of the city gross area, Chinese such as Beijing, Shanghai one
The urban road area accounting in line city also has been approached 10%, and still with the development of faster speed.Due to using hard surface
Urban road is developed at a too fast speed, and the central drainage facility in designing of city road is designed by 1~2 year chance standard substantially, works as incident
Urban road is difficult to the rainwash in time forming rainfall emptying when meeting the rainfall of super design standard, frequent so as to cause city
Waterlogging occurs, has seriously affected the normal life of city dweller and the development of urban economy.Portion 2010 is firmly built to 32, China
Display is investigated in the waterlogging situation in 351 cities in province, from 2008, has 213 cities to occur different degrees of
Ponding waterlogging accounts for the 62% of investigation city, and the frequency of urban waterlogging is in rising trend；The effectiveness factors 1 year city more than 3 times
The western and northern city such as just there are 137, or even are expanded to the Xi'an of drought, Shenyang.Firmly build the statistics also table in portion
Bright: Chinese city effectiveness factors maximum depth of accumulated water is more than that the city of 50mm accounts for 74.6%, and depth of accumulated water is more than that 15mm is more than
90%.；The ponding time is more than that the city of half an hour accounts for 78.9%, wherein the maximum ponding time for having 57 cities is more than 12 hours；
According to another the ground such as Beijing in recent years, Guangzhou, Chengdu, Wuhan it is successive caused by from the point of view of rainwater waterlogging event, urban waterlogging disaster is shown
Strong ascendant trend.
Expert thinks the " increasing of city Permeable stratum area after studying the reason of serious urban waterlogging in Wuhan in 2016 by analysis
It is more " it is one of them extremely important reason.Natural soils have the function of absorption and water moisture self restraint, by penetrating into rainwater
Underground, and mutually converted between the soil water and underground water, it revert to rainwater in nature, and then maintain city water cycle system
The balance of system.With the increase of urban construction path area, so that natural soils are gradually by concrete road surface and bituminous pavement etc.
Intimate impermeable stratum is covered, and the lower infiltration approach of rainwater has directly been cut off, and greatly reduces the infiltration capacity of soil, and rainwash
Amount and runoff coefficient are gradually increased, so that the water resource for being seeped into underground under this originally is changed into rainwash and can not infiltrate, thus
An important source as effectiveness factors.It is recorded according to Hubei Province's yearbook, since road is mated formation mostly with fluid-tight drip in Wuhan urban district
Based on green, cement pavement, therefore this construction considerably increases the Permeable stratum area in city.Furthermore the increase meeting of Permeable stratum area
Cause the Manning coefficient of original ground substantially to reduce, so as to shorten the rainwater conflux time, and then increases pipe network rainwater flow and pipe
Net burden, greatly improves the risk of urban rainstorm waterlogging.
The sponge urban construction technology of planning and test spread solution China is got worse China energetically
The urban construction new technology of urban waterlogging problem, and carried out some earlier test pilot works thus, investigation shows to be included in
In 30 cities of pilot, still there are this year 19 cities that waterlogging occurs, accounting 63% just includes Beijing, Tianjin, Chongqing among these
Equal municipalities directly under the Central Government, further include multiple provincial capitals such as Foochow, Wuhan, Jinan, Nanning.Some sponge cities for carrying out Pilot project construction do not have
There is the function of really making good use of natural soils absorption and water moisture self restraint in city, sponge urban construction is also not short time one or two years
It can complete.
Sponge urban construction is a system engineering, and the new city road construction for accounting for 10% or more the city gross area is sponge
One important component of urban construction, the new city highway layout of waterlogging is slowed down in current sponge city and construction is still in
Starting stage serves city road planning design system, road structure and evaluation method of sponge urban construction etc. also
Mature not to the utmost, reported the relevant technologies are also only limitted to using road surface seepy material technology, the technology non-motorized lane,
The urban roads such as pavement simply use permeable pavement, such as porous pavement, permeable ceramic pavement brick and pervious concrete, technology
It has the drawback that and does not pay attention to integrally using road surface, roadbed bed course, road lower part ground as a system, do not coordinate to examine
The water permeability for considering roadbed bed course, the rate of water absorption and storage capacity of ground under road, it is undesirable to eventually lead to implementation result, practical
Poor, the economy wretched insufficiency of property, it is difficult to effectively be promoted.
China's big and medium-sized cities waterlogging problem is got worse at present, and urban road area accounting is increasing, concentrate pipe network and
River has been unable to meet the requirement of municipal drainage, propose it is a kind of rainwater quickly can be discharged into underlying soil and give full play to soil storage
The new road structure of outlet capacity has very important significance, and is that one of the sponge urban construction that China widelys popularize is important
