(3) the lawn ecological water circulating system (seeing accompanying drawing 1)
The ecological water circulating system is after the precipitation with the sports ground sky is collected, to make irrigation, draining and retaining become the circulating system of a closure.Reduce tap water, chemical fertilizer and agricultural chemicals use amount to reach, promptly reduce the purpose that the lawn maintenance cost is protected environment again.
The ecological water circulating system comprises three subsystems.
Sewerage pipeline network is irritated on the lawn
Water pump and vacuum pump are irritated the drainage power system
Drainage pipe trench (pond) system
The ecological water circulating system is rainwater (ecological water) to be collected in through transformation have concurrently in drain function, water storage function, the gutter, the Trinitarian football field of irrigation function.During for lawn irrigation, with a submersible pump rainwater being taken out filling to the filling sewerage pipeline network that is distributed under the lawn at needs, is that the lawn root system supplies water through infiltrating irrigation.
When the needs draining, the water-supply valve that switches off the pump is opened the pipe network draining valve, and place seepage flow rainwater pipe network system under the lawn enters in the water draining and accumulating pipe trench.
When place behind the rain needs quick draining, can open vacuum pump, make and irritate sewerage pipeline network and produce negative pressure, thereby force to accelerate the seepage velocity of place rainwater, meet or exceed the standard of getting rid of rainwater behind International Football Union's rain in 30 minutes.

3, drainage pipe trench system
Around the football field gutter is set all, to compile the rainwater of surface runoff and subsurface seepage flow.For realizing the purpose of lawn ecological water closed circulation, the gutter is transformed, make it have the Trinitarian effect of draining, retaining and irrigation concurrently.
Stoplog lock (seeing accompanying drawing 2) at first is set in the termination, gutter, flows into the gutter rainwater with accumulation.
The stoplog lock is a kind of gate with crown_interception.Stoplog gate is by the independent flashboard of polylith, and block-by-block is laterally put into plane water-retaining structure of the folded full one-tenth of gate slot.After the stoplog lock was installed, the gutter had promptly had water storage function.When rainwater entered, the gutter became the retaining ditch; When rainwater is bigger, in the time of can causing place ponding, mention one or a few blocks stoplog lock flashboard, reach and promptly get rid of rainwater, unlikely again effect of retaining being arranged light.
Another technological transformation is the transformation to the draining furrow bank: will be embedded in many pvc pipes near the furrow bank in one side gutter, lawn, it is communicated with the gutter with the basis, place, and become permeable furrow bank (see figure 3).Its function is to make place part seepage water flow into the gutter, and the water of accumulation in ditch is penetrated in the basis, lawn by the capillarity of soil.Reach the effect of natural drainage and irrigation.
In the drainage ditch, lay submersible pump and link to each other, to realize that infiltrating irrigation is carried out on the lawn with the filling sewerage pipeline network.
The gutter has promptly had the Trinitarian effect of draining, retaining and irrigation like this.
Native system has following clear superiority:
1, substantially without running water, compare with spray irrigation system have obvious water saving economize can benefit;
2, fertilizer soluble in water, especially chemical fertilizer is recovered utilization, no longer enters environment with water, thereby has effectively prevented fertilizer, especially the pollution of chemical nitrogen fertilizer.
3, the agricultural chemicals (mainly containing pesticide, bactericide and herbicide) used of lawn is water-soluble, and the agricultural chemicals of tool residual hazard obtains recycling equally, eliminates or has alleviated the environmental pollution that agricultural chemicals causes.
4, the dissolved fertilizer that outflows with water, agricultural chemicals make the lawn reduce the use of chemical fertilizer and agricultural chemicals, namely after obtaining recycling. reduced the lawn maintenance cost
5, owing to exempting sprinkling irrigation, wet soil is wet careless during irrigation, and the wound when having protected the lawn to be pruned has effectively prevented Diseases of Turfgrass, the popular and generation of insect pest and crop smothering.
Do not affect ground on the scene motion when 6, the lawn being irrigated, increased place service time;
7, owing to exempted spray irrigation system, no longer bury the lifting shower nozzle in the sports ground underground, eliminated the Equestrian-Jumping thing, increased the security of place motion;
8, the water quality of utilizing the lawn to purify reaches the level that can breed fish, thus protection with improved the water environment of sports ground and surrounding area thereof.
