Description
Technical field
The invention belongs to salt-soda soil recycling of water resource to utilize field, more particularly, to a kind of saline and alkaline region water containing water discharging valve
Resource Collection utilization system.
Background technique
Rainwater is a kind of freshwater resources being of great rarity, and especially for beach saline land, this serious water shortage region is received
For collection with using rainwater, that is even more precious.Because of water shortage, the salt concentration in soil has exceeded the receiving of plant in salt-soda soil
Ability forms salt damage.Salt comes with water, and salt is gone with water, so must assure that sufficient freshwater resources supply, saline and alkaline soil money
Source can just accomplish sustainable use.
China's coastal saline-alkali soil gross area is up to 500 × 104hm2,.It is saline and alkaline in these years with economy and industrial expansion
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 control
The method in reason 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 will be saline and alkaline
The soil improvement on ground is good or after replacing with planting soil, aggregate chips is laid below planting soil, saline-alkali soil is isolated, prevent hair with high salt
Thin water enters good soil, then weeper drain is arranged under aggregate chips layer, and capillary haline water that infiltration comes up and good soil are arranged
Water is discharged in city planting ductwork in time.It is more than simultaneously drenching layer to prevent groundwater level, causes drenching layer to fail, greenery patches elevation is used
The earthwork is padded, generally padded to be at least higher than 1.5 meters of level of ground water peak or more, realizes further away from underground haline water,
The influence of capillary water with high salt is reduced, to guarantee to change good soil no longer by salination, can normally be afforested, plant is each
Kind plant.But the method defect that existing " aggregate chips drenching layer " adds " hidden pipe salt discharge " to administer salt-soda soil is: the rain after rainfall
After water penetration enters soil, lost through aggregate chips layer into saline and alkaline laminar flow, or be directly discharged into municipal drainage pipe network, rainwater cannot be effective
Utilization, while apply fertilizer during, the nutriments such as a large amount of N P and K have also been discharged into municipal rain system therewith, also cause
The eutrophication of downstream water；Have little time the rainwash rainwater of lower infiltration when rainfall, flow into the low gesture regions such as peripheral path, increases
Add road drainage pressure and waterlogging risk, while greenery patches soil washes away road surface with runoff, stays the runoffs such as mud after causing road rain
Pollution problem；It is big to afforest earth volume, it is uneconomical.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of saline and alkaline region water resource Collection utilization system containing water discharging valve
System；The system penetrates into the rainwater in planting soil layer after can effectively collecting rainfall, and not will lead to the saline-alkali soil layer accumulation of salt in the surface soil to kind
Plant soil layer；It is also possible to make the reduction of saline land greening absolute altitude, earth volume is reduced, while reducing to peripheries such as roads
The runoff pollution of facility.
In order to solve the first technical problem mentioned above, invention adopts the following technical scheme that:
A kind of saline and alkaline region water resource Collection utilization system containing water discharging valve, including soil ontology and venthole；The soil
Ontology includes the planting soil layer set gradually from top to bottom, permeable film layer, aquifer, waterproof layer and saline and alkaline soil layer；The plantation
It is separated between soil layer and aquifer by permeable film layer；It is separated between the aquifer and saline and alkaline soil layer by waterproof layer；It is described
Aquifer lower surface is equipped with the groove for charging into saline and alkaline soil layer, and hidden pipe is equipped in the groove, and municipal drainage system is led in hidden pipe outlet；
The junction of the soil outer body and neighboring buildings or structures uses lateral waterproof layer anti-package；The venthole is from soil
The planting soil layer of ontology extends downwardly into permeable film layer.
Preferably, the planting soil layer is with a thickness of 60-140cm.
Preferably, the permeable film layer is permeable non-woven fabrics.
Preferably, the aquifer is the aggregate chips or the macropores gap material such as rubble or pp module of 18-60cm thickness.

When very big preferably for greenery area, for convenient for managing and controlling, the saline and alkaline region containing water discharging valve
Water resource Collection utilization system can be divided into multiple water catchment areas, and different charge for remittance sections can be divided with waterproof geotextiles anti-package
Every；The turn up height generally more than 50cm above drenching layer.
Any range documented by the present invention includes any numerical value between end value and end value and end value or end value
Between any subrange for being constituted of any number.
Unless otherwise specified, each raw material in the present invention can be obtained by commercially available purchase, equipment used in the present invention
The conventional equipment in fields can be used or carried out referring to the prior art of fields.
Compared with prior art, the invention has the following beneficial effects:
A kind of saline and alkaline region water resource Collection utilization system containing water discharging valve of the present invention penetrates into kind after can effectively collecting rainfall
The rainwater in soil layer is planted, and not will lead to the saline-alkali soil layer accumulation of salt in the surface soil to planting soil layer；It is also possible to keep salt-soda soil green
Changing absolute altitude reduces, and reduces earth volume, while reducing the runoff pollution to peripheral facilities such as roads.
