Description
Technical field
The invention belongs to salt-soda soil water resource process fields, more particularly, to a kind of saline and alkaline region water containing seepage well and seepage pipe
Resource, which is regulated and stored, utilizes system.
Background technique
China's per capita water resource occupancy is only the 30% of world standard, most area water shortage or serious water shortage, in recent years
Come, increasing to the demand of water resource with the further in-depth of Development of China's Urbanization, how Efficient Development utilizes water resource
The challenge for needing to face jointly as the whole society.
In order to explore the sponge urban construction path under different natural environments, urban morphology, country has carried out two batches totally 30
A sponge city Pilot project construction, sponge urban construction at present is like a raging fire to be carried out in the whole nation, for various different underlays
It is emerged one after another using different rainwater-collecting purifications and the technology and product that utilize in face.Rainwater is a kind of fresh water being of great rarity
Resource, especially for beach saline land, this serious water shortage region collects and utilizes rainwater, that is even more precious.It is saline and alkaline
Ground is because of water shortage, and salt concentration has exceeded the ability to bear of plant in soil, forms salt damage.Salt comes with water, and salt is gone with water,
So must assure that sufficient freshwater resources supply, saline and alkaline land resource can just accomplish sustainable use.
China's coastal saline-alkali soil gross area is up to 500 × 104hm2,.In these years with economy and industrial expansion, salt-soda soil
Area has become the fresh position of economic development, and in order to meet the needs of Development control area, " aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer
The method in salt-soda soil is widely used.The method that " the aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer salt-soda soil is by salt-soda soil
Soil improvement is good or after replacing with planting soil, aggregate chips is laid below planting soil, saline-alkali soil is isolated, prevent capillary water with high salt
Into good soil, then under aggregate chips layer, weeper drain is set, water that the capillary haline water that comes up of infiltration and good soil are arranged and
When be discharged in city planting ductwork.It is more than simultaneously drenching layer to prevent groundwater level, causes drenching layer to fail, greenery patches elevation is padded with the earthwork
Height, it is generally padded to be at least higher than 1.5 meters of level of ground water peak or more, it realizes further away from underground haline water, reduces high
The influence of salt capillary water can be afforested normally to guarantee to change good soil no longer by salination, transplant various plants.
But the method defect that existing " aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer salt-soda soil is: the rain penetration after rainfall enters
After soil, lost through aggregate chips layer into saline and alkaline laminar flow, or be directly discharged into municipal drainage pipe network, rainwater cannot be utilized effectively, together
When fertilising during, the nutriments such as a large amount of N P and K have also been discharged into municipal rain system therewith, also cause downstream water
Eutrophication；Have little time the rainwash rainwater of lower infiltration when rainfall, flows into the low gesture regions such as peripheral path, increase road drainage
Pressure and waterlogging risk, while greenery patches soil washes away road surface with runoff, stays the runoffs pollution problem such as mud after causing road rain；Greening
Earth volume is big, uneconomical.
Summary of the invention
It regulates and stores utilization the technical problem to be solved in the present invention is to provide a kind of saline and alkaline region water resource containing seepage well and seepage pipe
System；The system is pooled to the rainwater on planting soil layer surface after can effectively collecting rainfall rapidly, and not will lead to saline-alkali soil layer
The accumulation of salt in the surface soil is to planting soil layer；It is also possible to make the reduction of saline land greening absolute altitude, earth volume is reduced, while reducing to road
The runoff pollution of the peripheral facilities such as road.
