Description
Technical field
The utility model is a kind of sports ground dmp filter stacking device, to filter accumulation unit for core, collecting by filtration is carried out to the rainwater on sports ground, not only solve the drainage problem of sports ground, and rainwater purification can be collected as afforestation etc. water resource is provided, belong to water resource and recycle field.
Background technology
Along with urban population increases severely and rapid economic development, but water resource is not enough, water pollution and ecological degeneration have become the key factor restricting China's industrial and agricultural production and urban development.Current China has entered serious water shortage period, due to natural rain have hardness low, pollute the advantages such as few, therefore, by the planning and designing of suiting measures to local conditions in conjunction with rainwater-collecting, utilize equipment to implement, reduce tap water consumption, can saving water resource, greatly alleviate the water shortage problem of China.
In prior art; existing by setting up subterranean tunnel water storage system, set up roof retaining and infiltrate the earth's surface recharge system of pond, well, meadow, pervious surface composition; allow rainwater is roundabout to be stranded in once by the soil of levee protection; both make use of the ecological environment ability of flood, alleviate the pressure of flood in other areas simultaneously.
Current rainwater utilization system comprises accumulation and utilizes storm-water system, and building area or the accumulation of cell set Chinese style rainwater utilize system, distributing rainwater penetration system, centralized rainwater penetration system, and roof greening rainwater utilizes system, ecodistrict rainwater comprehensive utilization system etc.Specifically, the utilization of rainwater mainly comprises the following aspects: the accumulation of (1) rainwater utilizes, and in order to alleviate current city water resource situation in short supply, is a kind of effective way of increasing income and decreasing expenditure; (2) indirect utilization of rainwater, recharges rainwater infiltration to underground, supplements recharging groundwater resource, improves the ecological environment and alleviates surface settlement and seawater invasion, reduces waterlogging etc.; (3) rainwater comprehensive utilization, utilize urban rivers and lakes and various artificial and natural water, marsh, wetland is regulated and stored, and purifies and utilize urban runoff rainwater, reduces waterlogging, improves Water Environment System and urban ecological environment.In addition, if rainwater utilization technology is full-fledged, not only can alleviate the situation of domestic short water supply, the country of other serious water shortages can also be exported to, up to the present, the expense of seawater desalination system is far away higher than the expense of import water, and therefore the Collection utilization of rainwater can play important impetus to the development of domestic economy construction.
Chinese patent CN98102003.8 sports ground forces rapid drainage method and drainage system thereof, lay drainage pipeline networks in the bottom on athletic ground, at the outside of pipe network parcel filter layer of cloth, rough sand layer or sand mixed layer is laid around pipe network, pipeline is all certain gradient to delivery port direction, certain drainage by suction is formed at total delivery port of pipe network, drainage pipeline networks is arranged in the plane of sports ground in both sides to dividing with axis according to certain spacing, and the end of sports ground is pooled to along the both sides of sports ground, form negative pressure by vacuum pump at water outlet; Ooze under oozing the pressure become under condition of negative pressure under making rainfall lean on natural gravity, comparatively conventional drainage system shortens time 4-5 doubly.The weak point of this patent is: the outside parcel filter layer of cloth of pipe network, makes draining not rapid: around pipe network, to lay rough sand layer or sand mixed layer, very easily being stopped draining by tracking tramping; And for the cement floor of plastic sports ground, can not ensure the stability on athletic ground in this structure of underground mining, have potential safety hazard, therefore this structure is not suitable for applying in modern sport place.
