Description
Technical field
The present invention relates to urban water supply and sewerage technical field, is a kind of for alleviating urban flood defence pressure, and collects rainwater and make it store to support water storage type greenery patches structure in half of underground.
Background technology
Along with the quickening of urbanization process, increasing ground by concrete and pitch cover, the large-area sclerosis in earth's surface very easily produces flood when making to meet precipitation on the way, thus produce that peak flood flow increases, peak now in advance, a series of urban waterlogging problem such as conflux networks increase, add the threat of city flood, while bringing inconvenience to the trip of people and life, also fail city flood resource effectively to utilize.
For problems, corresponding measure is taked in some cities, build a collection of underground flood storage project, alleviate the pressure of flood in city to a certain extent, but effect is remarkable not, mainly there is following several respects problem: 1, descend flood storage pond difficulty of construction large routinely, cost is high, and retaining is measured one's own ability limited, function singleness; 2, because earth's surface, underground pollution thing enter water-accumulating body with current, the water quality of retaining can not get effective guarantee; 3, support engineering must be built in common water-accumulating body top, and not only engineering quantity is large, and the maintenance being not easy to the water-accumulating body later stage improves.
Therefore, be necessary to research and develop the water storage type green space system that can make up these aspect deficiencies, effectively to improve urban flood defence ability, solve rain-flood resources Utilizing question, ensure the security of the lives and property of townsfolk.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of can cut down city flood peak value, store half of city flood resource urban flood defence and utilization of flood resources and support water storage type greenery patches structure.
Technical scheme: for solving the problems of the technologies described above, half support water storage type greenery patches structure of a kind of urban flood defence provided by the invention and utilization of flood resources, comprise Rainfall Infiltration structure, underground storage body water delivery water purification structure and water intaking water-using structure, described Rainfall Infiltration structure comprises let, greenery patches backfill and the first Water penetrative flexible pipe, is connected under described first Water penetrative flexible pipe is laterally located at greenery patches backfill with let; Described underground storage body water delivery water purification structure comprises the rigid protection of geotextile, general permeable material, the second Water penetrative flexible pipe and both sides, described geotextile is layed in below the first Water penetrative flexible pipe, the below of geotextile is located at by described general permeable material, and described second Water penetrative flexible pipe is laterally located at below general permeable material; Described water intaking water-using structure comprises the intake, manhole and the 3rd Water penetrative flexible pipe that set gradually straight down from earth's surface, and described 3rd Water penetrative flexible pipe is connected with the second Water penetrative flexible pipe.
Preferably, described Rainfall Infiltration structure is positioned at the superiors, described underground storage body water delivery water purification structure is positioned at below Rainfall Infiltration structure, described water intaking water-using structure is arranged in underground storage body water delivery water purification structure and Rainfall Infiltration structure, also water-using structure of namely fetching water is connected with underground storage body water delivery water purification structure and Rainfall Infiltration close structure, utilizes the 3rd Water penetrative flexible pipe fully can absorb the moisture of underground storage body water delivery water purification structure and Rainfall Infiltration structure.
Preferably, described greenery patches structure is located at recess under earth's surface, and adjoins with urban pavement.
Preferably, described rigid protection adopts steel concrete or cemented rock structure, and consistent with the trend of let.And only vertical setting, supporting is not done in water-accumulating body top, does not change original Landscape.The structure of diaphragm wall can be adopted
Preferably, described geotextile is drainage type geotextile, allows water to pass through, and stop fine grained soils to outflow with water, rainwater is seeped into water-accumulating body by under geotextile, is also directly communicated to gutter.
Preferably, described general permeable material level, in geotextile lower floor, can utilize building waste, and rainwater can be accumulated in its own space, and plays certain supporting role.
Preferably, underground storage body water delivery water purification structural top does not do supporting, does not change original earth's surface green landscape; Underground storage body water delivery water purification structural base adopts open design, utilizes original soil to seepage in underground, utilizes the filtration of soil to adsorb and clean water source is added to underground water.
Beneficial effect: the present invention contrasts prior art and has the following advantages:
1. effective flood peak clipping, increases Flood Control Dispatch ability.
In urbanization the large area sclerosis on earth's surface make that peak flood flow increases, peak now in advance, conflux networks increase etc., people is the threat adding city flood.After large area greenery patches changes water-accumulating body into, the magnitude that lower milliosmolarity reduces the output of surface flow, water-accumulating body decreases flood peak, plays the effect of flood control and disaster reduction.
When prediction has heavy showers to occur, to be drawn water discharge by manhole, what add water-accumulating body can water retention capacity, improves the resist ability to flood, for urban flood defence with the addition of the function of Flood Control Dispatch.
Water-accumulating body long-term stability to groundwater recharge, alleviate the order of severity of Urban Underground hyponome, to a certain extent the water resource of high flow year be accumulated in underground water, improve the anti-disaster ability of drought.
2. realize the accumulation of city flood, purification, use integration.
Geotextile is provided with in water-accumulating body, the structures such as general permeable material, can play a role in filtering when rainwater infiltration thus improve the water quality in water-accumulating body, when water-accumulating body hypervolia, oppositely can go out stream by Water penetrative flexible pipe to gutter, play the effect of clean geotextile and Water penetrative flexible pipe.As long as water-accumulating body has water, just can pumping irrigation greenery patches, spray road surface, save a large amount of tap water, compared with similar underground flood storage pond, difficulty of construction is little, cost is low, and purposes is more extensive.
Except technical problem, the technical characteristic forming technical scheme and the advantage brought by the technical characteristic of these technical schemes that the present invention recited above solves, half of a kind of urban flood defence of the present invention and utilization of flood resources supports the advantage that the other technologies feature that comprises in other technologies problem that water storage type greenery patches structure can solve, technical scheme and these technical characteristics bring, and will be described in more detail by reference to the accompanying drawings.
