Abstract
A sports field without dust fly is composed of surface layer, water-filtering layer made of sand, cobble, or earthwork cloth, water-bearing layer made up of cobble, broken rock, cinder, or high-porosity water-permeable material, impervious layer made of earthwork film, clay, asphalt concrete, or plastic film, and water supply and drainage ditches at one side or periphery of said sports field.
Description
The present invention relates to native playground earth construction, particularly can prevent the playground surface layer structure of ground dust storm airborne dust.
At present, ground, known native playground surface layer is to adopt clay, slag and the composite tabia making of quicklime, simplification also can directly adopt sandy loam or clay making.The bottom of surface layer is a macadam, plays the effect of drainage and anti-freeze expansion.That simplifies also can not establish macadam.Therefore, the earth construction on conventional native playground is made up of macadam and tabia.This native playground is laid easy, and required expense is less, but a very important shortcoming is serious at dry and rainless dust from land surface in season, and ground stirs up a cloud of dust when wind is big, and the student moves on the playground and also can raise a huge cloud of dust in the time of even without wind.Particularly in the season in spring and autumn of northern China, the dust from land surface personnel that make in playground are difficult to admission, influence the use on playground.When rainy season, because of rainwater is too big, native playground is muddy to can't bear, and can not use.Adopt the playground of plastic coat or artificial grass surface layer can solve the dust from land surface problem, but expense is very high, is difficult at present popularize; Adopt natural sod ground also can solve the airborne dust problem, because can not full-time opening,, move maintenance costs simultaneously again also than higher so be not suitable for student movement.Adopt the method for surface watering, when the watering amount more after a little while, it is very short that the moistening time is kept on ground, can not really solve the airborne dust problem; When the watering amount more for a long time because the soil layer seepage velocity is very slow, tend to cause water loss at ground surface.Excessive trickle can make ground, playground mire, makes the personnel can not the admission activity.On the other hand, part moisture can be lost in the air in the watering process, and surface evaporation speed can cause the waste of water resource also than comparatively fast.Test shows that also the top layer watering can cause soil layer loose, easier airborne dust after drying.In the surface layer of playground, lay equipment of sprinkler irrigation, can realize control watering automatically, but have the problems referred to above equally.
The purpose of this invention is to provide a kind of problem that can effectively solve the playground dust from land surface, water-saving, operation maintenance are easy, the sports field without dust fly that ground is not muddy.
The object of the present invention is achieved like this, and ground, playground is made of surface layer, drainage layer, water storage layer and impervious barrier and water supply and draining ditch.Be surface layer topmost, surface layer according to the earth material situation of locality can be with tabia, be stained with, making on loam or the sandy loam; Be the drainage layer below the surface layer, the drainage layer can adopt sandy gravel to lay by artificial loaded filter requirement in the hydraulic engineering, also can directly adopt geotextiles, and its effect is that the soil body of surface layer and water storage layer are isolated, and prevents that the water storage layer is silted up; The water storage layer can adopt cobble, evenly rubble, slag or other macroporosity seepy material of grating are laid, and the rubble diameter is 10～30mm, and its effect is water and can makes water be easy to flow to replenish the water source; Be impervious barrier below the water storage layer, its effect is that to prevent that water in the water storage layer is penetrated into underground, and impervious barrier can adopt geomembrane or composite geo-membrane, clay, bituminous concrete or plastic film material to lay.For the permeability that keeps soil layer below the impervious barrier with prevent that geomembrane etc. is punctured, and also can lay certain thickness layer of sand or flyash under impervious barrier.
Advantage of the present invention is: owing to be based on the soil suction characteristic, make moisture rise to the surface layer soil body from the water storage layer, so moisture distribution is very even, under the condition of the porosity of controlling the thickness of the layer and the soil body prevailingly, water supply water surface elevation and output, can guarantee neither muddy, the also airborne dust not of layer of ground soil.Because from the bottom suction, can not destroy the surface soil structure, during local area water of while (as rainfall), the water in the surface layer can also enter the water storage layer by the drainage layer and also can be got rid of by irrigation canals and ditches that supply water or water pipe.Preliminary test shows: in the spring of China the Northeast, a water storage can be kept two weeks or longer time airborne dust not.Simultaneously because the deck that increases newly has drainage and drain function, so can also cancel macadam.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a playground of the present invention earth construction sectional drawing.
Fig. 2 is the I-I sectional view of Fig. 1.
Fig. 3 is the local enlarged diagram that indicates the position among Fig. 1.
The sports field without dust fly earth construction as shown in Figure 1, Figure 2, Figure 3 and Figure 4. Playground periphery or certain Side is established the gutter, establishes in the gutter 6 for ditch 9, adopts for ditch and ground, playground water storage layer 3 sides adjacent With permeable barricade 8, will separate for ditch and water storage layer, guarantee that simultaneously water can be easy to see through barricade and annotate Enter the water storage layer. Base plate and 4 airtight connections of ground, playground impervious barrier for the ditch. Connect water supply for the ditch System, water supply can be adopted rainwater or the treated urban water of underground water, collection. For the ditch Opposite side be waterproof barricade 10, waterproof wall height can be in order to control at the water storage layer more than 3 Feed water level regulation processed makes on the highest height that remains on waterproof barricade of level of ground water in the water storage layer. When To in the ditch during water-filling, water can very fast inflow water storage layer, surpasses the height of waterproof barricade when water level When spending, will automatic overflow enter the gutter 6 in the outside for the water in the ditch, discharge pipe line is passed through in the gutter Insert sewerage system 7. Therefore drainage layer 2 and water storage layer also have drainage during rainfall, thereby Can very fast admission after the assurance rainfall. On the ditch, be provided with permeable cover plate 11.
The design content of playground of the present invention earth construction comprises: (1) is by testing the physical force of conventional soil Learn the test of attribute testing and soil moisture characteristic, reasonably determine thickness, the earth material of surface layer grating, Compacted density and porosity; (2) design drainage layer, water storage layer and impervious barrier are according to the actual feelings at scene Condition is determined each layer material therefor. When selecting geomembrane as impervious barrier, optionally can select a cloth The compound upper worker's film of one film or two cloth, one film is wanted the tension of verification geomembrane and resists to puncture intensity during construction, When the drainage layer uses upper worker's cloth, can select the lower geotextiles of mass area ratio with joint as far as possible The investment-saving, but verification tensile strength and the anti-intensity that punctures also wanted when constructing; (3) design playground periphery supplies Drainage system.
When making by the water supply ditch in the water storage layer behind the water-filling, the water under capillarity in the water storage layer can see through the ground motion of drainage course, makes the playground surface layer moistening.The water content of surface layer reduces from bottom to top gradually, to the ground surface minimum.The thickness of control surface layer, the water surface elevation of feedwater and confluent be the moistening degree of water content of face soil controllably.Impervious barrier has guaranteed that water can be to following infiltration.Test shows, moistening can the keeping the long period of once feeding water.
