Description
Technical field
The present invention relates to a kind of prefabricated pile apparatus and method of the fast permeable speed of self-pressurization, belong to applying in field of civil engineering
Work technology class, mainly applies city sponge urban construction, accelerates rainwater to the infiltration in the soil body.
Background technology
In conventional urban construction, the control of rainwater is with " quick to exclude " and " end concentration " as basic concept.And it is this
Exactly there is the major reason of urban waterlogging in way.A large amount of rainwater are drained, and typically using coarse pipe duct system, realize rainwater
Collect and concentrate nearby discharge.If running into heavy rain, a large amount of rainfall runofves and its pollutant of carrying are defeated in the shorter time
Pipe duct end is delivered to, causes downstream area waterlogging increased risk.
In fact, if leaving rather than draining most of rainwater, can to greatest extent realize rainwater in urban area
Accumulation, infiltration and purify, promote rainwater resource utilization and ecological environmental protection.Stay few row more rainwater, be just " sponge city
The basic concept in city ".
Sponge city is exactly to liken city as sponge, runs into and " can absorb, deposit on the spot or nearby when having rainfall
Storage, infiltration, purification " runoff rainwater, recharge of groundwater, regulation water circulation, the water that will be stored of having ready conditions in drought and water shortage " is released
Put " out and it is used, so as to allow migratory movement of the water in city more " nature ".That is, " sponge city " has
Hoping will be digested before the water extraction for draining into pipe duct end in a large number originally by the link such as absorbing, saving, permeating, and be become to crack and " be met rain
Must flood " effective way.
After sponge city is built up, the rainwater drained and the rainwater for staying will realize " projecting ".Such as, with previous seat city
70% water is all discharged into soon drains into pipeline, and sponge city will then allow 70% water to stay.
Sponge city refers to that city can have as sponge the aspect such as environmental change and reply natural disaster is adapted to
Good " elasticity ", water suction, water-retention, infiltration, water purification, the water for storing when needing discharged and be used when raining.Sponge city
City's construction should follow the principles such as Ecology Precedence, by natural way in combination with artificial measures, guarantee municipal drainage prevention waterlogging safety
On the premise of, accumulation, infiltration and purification of the rainwater in urban area is realized to greatest extent, promote the utilization and life of rainwater resource
State environmental conservation.In sponge Process of Urban Development, the systematicness of natural precipitation, surface water and groundwater should be planned as a whole, coordinate to
The each link of the water circulation uses such as water, draining, and consider its complexity and chronicity.A kind of prefabricated pile dress of the fast permeable speed of self-pressurization
Put and method, mainly apply city sponge urban construction, accelerate rainwater to the infiltration in the soil body, final purpose is that rainwater to the greatest extent may be used
More than energy stay in " spongy body " more.
