Description
Technical field
The present invention relates to sports ground, the particularly artificial sports field including artificial turf.The invention further relates to this
The building method and its water management of sports ground and cooling.
Background technology
Known various artificial and half artificial sports field's system.Half artificial court is usually directed to is incorporated into soil by artificial blade of grass
In base, conventional turf grass growth is allowed in the soil base.Other soil base and its draining are set can be with conventional natural grass
The similar appropriate growth to ensure natural grass in court.
Complete people pelletizing is from the Astroturf of the first generationTMFourth-generation system till now, it attempts will be natural
The functional and characteristic of turf is all bound in single product.In artificial court is laid, a primary demand is thereon
It is capable of the appropriate base of laying technology layer.The a big chunk for the overall cost newly installed can be to prepare base.This should be carried
The stabilization and draining level of guarantee are provided with, despite the fact that being that following earth's surface can have very big with the difference in touchdown point or area
It is different.
Another feature of artificial sports field is to be difficult to handle high temperature (such as in the presence of bright sunlight).The table of sports ground
Face temperature can be substantially increased during daytime, so as to change the characteristic of technology layer, even send niff.At these
Ratio grand sports meet under part is affected.Other sports grounds may require that irrigation before match can start.In all situations, water pipe
Reason be designer must design sports ground when the key problem to be taken into account.
Term " water management " refers to four main aspects, and these aspects are：Draining, is irrigated, storage and decay
(attenuation)。
Draining may be defined as draining into water into the EXIT POINT constructed away from sports ground from court region.Excessive water or surface
Waterflooding will have detrimental effect to games results, and can cause the movement of filler material.
Irrigation may be defined as that water is sent on turf surface by the system of pump, Pop-up water sprinkler and water cannon.Will
The purpose that water adds to surface can be a part for the match characteristic as surface, or to cool down turf surface.In sweltering heat
Sunlight conditions in, artificial grass turf system can be warming up to surface become it is uncomfortable and consumption sportsman energy degree.
Storage, which may be defined as providing, accommodates equipment, and the receiving equipment allows to discharge with used in such as court from court
Water in irrigation enters.It can be in the cistern of underground or the reservoir of ground.Storage is also connected with water fade.
Decay may be defined as interim in the reservoir of surface water in the appropriate cistern less than ground level or on the ground
Storage.The cistern or reservoir need with enough sizes to be contained in the runoff being computed of rainfall peak period.Then storage
The water deposited can gradually be released into the drainage system or water channel of combination in a controlled manner, so as to effectively reduce waterflooding
Risk.
Drainage system
The conventional drainage methodology of artificial grass turf system is based on two main methods.First is vertical process, another
It is then horizontal process.
Vertical process：There are many modifications and system under the title of vertical drainage, but general principle keeps constant, that is, is located at
The matrix or pattern of the antipriming pipe of the interconnection of porous ground mass construction bottom.Porous base tectonic sieving is into removing from superincumbent
The water that artificial grass turf system is permeated by the upper strata of porous stone base.Water is taken away playing area and made it into by these pipes
Annular main land drainage or similar drainage control system.
These courts can have the profile for helping water movement；This is referred to as slope or descending.The slope on ionized motion surface
There are various designs with descending, for example：Plus top formula, enclosed, and tilting etc..Angle downwards are intended to 0.4%
And between 1%.Porous ground mass it is a key issue that because the rock compaction amount that can be realized is limited, it is therefore desirable to porous ground mass
With minimum construction depth.The target of any base configuration is to reach to ensure that structure has appropriate structural intergrity and carrying
The a certain test value of ability.For example, a kind of industry standard methods for measuring these values are referred to as Californian Bearing
(CBR is always according to BS 1377-2 by Ratio:1990 define), it represents with percent value.For sports ground, after mounting
Standard target CBR values minimum 30%.In order to realize the value, bigger depth is must take into consideration for porous base construction.This be because
Include interstitial space for porous stone construction, so that water passes through structure.As a result, compared with equal non-porous base construction,
The bulk strength of the structure is not high, and rock has bigger mobility.
Presence of the water in porous stone construction also promotes the further stability of destruction stratum (formation) and causes ground
Layer is easily by frost heave.In order to solve these problems, according to local geology and weather conditions, porous ground mass generally has 300mm's
Minimum-depth.
Another problem is that needing the expensive rock type particularly matched somebody with somebody through level to produce porous basic unit.The rock comes freely
The raw material of truck transport.For 7500m2Standard multi-well court construction and 300mm minimum rock depth, it would be desirable to
2475m3Or 4200 tonnes of rock.20 tonnes can be delivered in view of the truck of standard, this will require about 200 truck loads.
In addition, in addition it is also necessary to the number of truck of extra 200 truck load come remove the subsoil both deposited so that its reset or landfill waste.
Not only cost is high but also effect on environment is also very big for the demand of this use of raw material and 400 times truck strokes.
Horizontal process：Described above, vertical drainage method is dependent on porous base construction is created, and the porous base, which is constructed, to be caused
Water is lower to following sports ground drainage with oozing by porous stone step.Horizontal process uses the limited or non-porous rock of porosity
Stone base is constructed, and does not have sports ground drainage below.General principle is the surface that water flows through artificial turf, flows through filler, and
Flow into some cases in damping mat substrate, the damping mat substrate causes water flatly to be flowed on rock base construction
It is dynamic.In being had a system and method which, court is designed to slope or descending (described above) ensure appropriate water
Stream.The water on outflow sports ground surface is then collected by the rhone or drainpipe installed around turf device periphery.These pipes
There is slope or descending water is moved into main land drainage or similar drainage control system for itself.
Such system is that possible reduce base configuration depth relative to the benefit that porous base is constructed, because these stratum are not
Need interstitial space and thus, it is possible to be compacted.The rock type can have wider particle size, so as to reduce extraction
Rock cost.It is also possible to regeneration aggregate is used in this base configuration form, such as regeneration brick, concrete, pitch
The aggregate of production.Because these surfaces are non-porous or porosity is limited, water is to the structure of basic unit almost without shadow
Ring and therefore limit frost heave and unstable effect.In some cases, it may be desirable to which impermeable lining is installed at the top of rock layers
Pad.Discharged in order that obtaining water from surface, will require that court has descending or slope.The slope can be in a direction or multiple
Constructed in a variety of ways on direction.The construction on this slope needs the technology of court builder, and influences the turf of completion
The ball operation conditions on surface.Further it is necessary to which mounting layer is to make water freely under the shifting of slope between turf and base configuration
To the drainage on periphery.The layer can be by certain form of beam and/or geotextile (geo-technical fabric)
To provide.
A kind of horizontal drainage method for sports ground proposes that it is using in impermeable table in WO2012138216
Porous ground (sub-grade) layer laid on face builds the edge that water is delivered to court by (course), the edge energy in court
It is enough to drain water by conventional drainage.Also propose use ground layer build as receiving area (containment), for example to
Competition Surface is recirculated to, as described below.
Irrigate
The irrigation system of standard depends on the water supplied from total pipeline, and it is pumped on court or around court
Water cannon or Pop-up water sprinkler.In some cases, the water collected from court drainage system is piped into storage to set
In standby and it is recycled back to by water cannon or Pop-up water sprinkler on court.Filter plant is also needed in this case.Water
Use as a part for turf system performance or be used as cooling during hot weather.For full-scale hockey
, 12000 to 18000 liters are may require that before match to soak the court.
All these methods depend on identical general principle, wherein water is applied to the top of turf system and water gradually
Discharged from turf structure.Water can not during indwelling is any on the spot or the long-term time limit, therefore its in terms of performance or cooling to grass
The influence of dermal system has limited short run effect.Because most of artificial turf fibres and filler are not inhaled nearly or completely
Performance is received, so water flows away simply by turf system.The method that water is applied by water cannon or water sprinkler be it is very poorly efficient,
Because the water applied much all just loses as steam before reaching the surface, and the accuracy that water cloth is put also is difficult to control
System.The cost of such system is also high, and is also had an impact to finance and environment using the water supplied directly from total pipeline.
Water is stored
If the requirement or legal obligation to engineering be reuse from court drainage system collect water, or if this
Water cannot directly enter the drainage system of locality, then the storage cistern or reservoir of ground or underground can be constructed near court.As above
Described, some designs will make it that the water collected is filled on the Competition Surface for field of returning serve.The cost for installing storage cistern or reservoir is high, and
And be must be arranged at around the region in court beside such construction.In many situations, solution is to dig huge hole and cover
Hide storage cistern.Additionally have problems that the water of preservation by microorganism and algae pollution.This can be eliminated to the water process
The invasion of sample, it is noted that monitoring and handling the water of the preservation.
Extreme at another, in the region of sinking rainfall, sustainable water storage or rainwater-collecting are the known habits of one kind
Used way.These methods include ground and roof collection, underground dykes and dams and the recharge of ground water.
Decay
Separate flow system system (SUDS) or low influence drainage system (LID) are a development concepts, and it is relevant
The decision-making of draining includes long-term environment and social factor.It considers the quality and quantity and surface water of runoff in city
Comfortable value in environment.Many existing sewerage systems, which can cause, to flood, pollutes or the problem of welding, not
It is proved to be sustainable.
Region more than building needs draining to remove surface water.Generally this is completed with underground piping system, described
Underground piping system is designed based on quantity, i.e., local flood is prevented by being as soon as possible transported away water.But, flow naturally
The change of pattern can result in the problem of catchmenting elsewhere.In addition, such as water in terms of also largely ignoring amenities
The facility of source, community's equipment, beautification of landscape possibility and various wild animals and plants habitats.
SUDS systems are designed to during torrential rain event and played afterwards aggregation, storage and the work for gradually discharging rainwater
With.Existing various types of city systems；From percolation well, multiple basements to open storage reservoir etc., all of which is set
Counting into ensures that the rainwater from non-porous surface such as road, roof and the aggregation of parking of automobile place is directed, stored, and then slow
Slowly discharged with controlled manageable flow velocity into drainage system.
The major defect of these systems is the fact that they need the city position for building shortage in.Due to sand, glue
The permeability formation at leisure such as native and thin dirt, so dependent on to preserve water and then make water slowly by ground seepage flow
System of the percolation well or level of dissipation with petrographic province is also easy to silt up.
