Description
Technical Field
The utility model belongs to the technical field of the construction in sports ground, especially, relate to a crack type sports ground is split to permeate water.
Background
In the field, the impervious ground surface represented by a road and a hard pavement and the permeable interface represented by a green land are main components of the field, and the proportioning relationship of the impervious ground surface and the green land is obviously negative and plays a role in an ecosystem in a contrary way.
From the perspective of water balance, the impervious ground surface cuts off a natural infiltration channel of rainwater, so that the surface runoff is greatly increased, the ecological environment of a field is damaged, and a large amount of runoff pollution is generated; and the ground surfaces with better water permeability such as green lands and the like, even the permeable pavement with poorer base layer water permeability (such as clay) can reduce the surface runoff by more than 90 percent compared with the impermeable ground surfaces such as asphalt pavements and the like, and simultaneously the concentration of pollutants in the runoff is also reduced to different degrees.
In the aspect of urban heat island effect, as an important factor influencing the surface temperature, in areas with high water-impermeable surface coverage, most of heat is sensible heat exchange to cause surface temperature rise, and the exponential function relationship between the two means that the higher the proportion of the water-impermeable surface is, the faster the surface temperature rise is; in areas with high vegetation and water coverage, the surface temperature is reduced because most of heat is latent heat exchange due to transpiration.
In addition, the impervious ground surface can also influence groundwater replenishment to cause ground surface subsidence, increase flood disaster occurrence probability, increase urban rainwater municipal system burden and the like. In the process of urbanization, the proportion of the impermeable ground surface in the field tends to be larger and larger. While the hazard of a watertight surface in a single site is not obvious, the cumulative impact of multiple such sites on the environment is not negligible. Therefore, on the premise of meeting the use function of the field, the ecological water-proof land has positive ecological significance.
In order to implement national strategy of fitness of the whole people, popularize fitness sports of the whole people and promote the construction of healthy China, cities, towns and schools increase the investment of sports facilities, more and more sports fields (such as basketball courts, tennis courts, badminton courts, runways, leisure squares and the like) are constructed, and the foundation layers of the fields are constructed basically according to the design construction scheme of light-load impervious roads. The common cement concrete foundation layer or the dense-graded asphalt concrete foundation layer is generally adopted, and the surface layer is mostly made of plastic, and belongs to a waterproof field.
Taking the construction scheme of a tennis court as an example, a construction unit provides two schemes for the owner to select: 1) the soil base +30cm thickness 3:7 gray soil +50cm inorganic material layer +5cm coarse grain type asphalt concrete +3cm fine grain type asphalt concrete + hard acrylic acid 1.3mm from bottom to top. 2) The cement structure base layer and the elastic acrylic acid are 3-5 mm. The two fields are impermeable fields, the compression strength of the ash soil and inorganic material base layer plastic is high, but the tensile strength is obviously insufficient, uneven settlement or cracking can occur when the construction quality is poor, cracks or depressions appear on the plastic surface of the field, and the normal use of the field is affected.
The surface of the traditional sports ground foundation layer is compact, and rainwater needs to flow to the peripheral drainage ditch through the ground surface and is discharged. In case of heavy rain, rainwater can not be drained in time frequently, so that surface water of the sports ground is accumulated, and the sports ground can be put into use after being dragged to dry after raining.
In high-temperature weather, the heat of the common cement concrete foundation layer or the dense-graded asphalt foundation layer is not easy to dissipate, so that the temperature of the plastic surface layer is increased, and the aging of the surface layer is accelerated. Harmful substances in the high-temperature medium plastic sports ground are easily decomposed and volatilized into the air, so that the harm is caused to the surrounding environment and the health of sports personnel. For a common plastic field, renovation is carried out basically every 5 to 8 years, the maintenance cost is high, and the renovation cost of only surface layer plastic reaches about hundred yuan per square meter.
