Description
Technical Field
The invention relates to a road rainwater collection system which is beneficial to improving the heat island effect of a residential area and is suitable for collecting rainwater on the ground and the road surface of a living community, an entertainment and leisure activity place and other similar occasions.
background
The heat island effect is a phenomenon that the temperature of a region is higher than that of the surrounding region, because a large amount of artificial heat is generated in a city, and meanwhile, because high heat accumulators such as buildings and roads and the like and the greenbelt are reduced, the temperature of the city is high, so that the temperature of the local region of the city is obviously higher than that of the peripheral region, usually, on a temperature map near the ground, the temperature change of the suburb is small, and the city is a high-temperature region, namely an island protruding out of the sea. For example, a large number of artificial structures such as concrete, asphalt pavement, various building wall surfaces and the like in cities change the thermal property of the underlying surface, and the artificial structures absorb heat quickly and have small heat capacity, and under the same solar radiation condition, the artificial structures are heated more quickly than the natural underlying surface (greenbelt, water surface and the like), so that the surface temperature of the artificial structures is obviously higher than that of the natural underlying surface; as another example, urban surfaces have less water content and more heat enters the air in the form of sensible heat, causing the air to heat up. Meanwhile, the absorption rate of the urban ground surface to sunlight is higher than that of the natural ground surface, more solar radiation can be absorbed, more heat can be obtained by air, and the temperature is increased. In summer, when the lawn temperature is 32 ℃ and the tree crown temperature is 30 ℃, the temperature of the cement ground can reach 57 ℃, the temperature of the asphalt road is higher than 63 ℃, and the high-temperature objects form a huge heat source to bake the surrounding atmosphere. Therefore, changing the heat island effect requires many-sided work, in which the living environment of residents in a residential area is improved, and under the condition that the greenery use land is limited, a road rainwater collection system capable of effectively relieving the phenomenon is designed, and the heat island effect of the residential area is relieved by rainwater.
In order to meet the requirements of sponge cities, rainwater resources are effectively utilized, urban waterlogging is avoided, the water seepage pavement (ground) technology is developed, and the existing water seepage pavement is mainly paved by adopting various ground plates with certain water seepage/water permeability, so that the ground accumulated water seeps into a soil layer below the plates through the ground plates. The present infiltration/board that permeates water (the brick that permeates water) has multiform, one kind is the brick that permeates water (or called lawn brick) that sets up vertical through-hole, the through-hole on this kind of brick that permeates water is the macroscopic view through-hole, utilize the model shaping, downthehole filling is planted soil and is planted herbaceous plant, planting soil in the through-hole links to each other with the soil of ground under the brick, consequently, to some places that are adapted to vegetation, the application of this kind of brick that permeates water can gain better effect, can set up on parking area or road bank protection usually, the rainwater permeates downwards in the soil layer through these through-holes after raining. Because the through holes of the permeable brick are large, the formed road surface is uneven and is not suitable for roads or places where people walk or move.
The other type of water permeable brick depends on the porosity of the material, and mainly comprises sand-based water permeable bricks mainly made of sand and a binder and stone-based water permeable bricks mainly made of broken stones and cement (concrete), wherein the stone-based water permeable bricks are low in cost, rough in surface, poor in aesthetic effect and easy to block by soil carried in water, the sand-based water permeable bricks are relatively high in cost, better in appearance than the stone-based water permeable bricks, limited in water permeability, and also capable of being blocked, and the sand-based water permeable bricks are limited in strength and incapable of bearing larger pressure. In addition, the ecological water permeable bricks belong to sand-based water permeable bricks, and the water permeable performance and the pollutant adsorption performance are improved by using a certain treatment material and a preparation process, so that the water permeable capacity of the product is improved, the product is not easy to block, and the ecological water permeable bricks can be popularized and utilized in occasions with higher requirements.
However, in many cases, for example, the foundation of the pavement of a residential area (including the ground of an outdoor activity place) is mostly a hardened foundation or is doped with a large amount of building residue and soil, and the water permeability is poor, so that water permeating the lower part of the brick is difficult to continuously permeate downwards when the water permeable brick is laid on the foundation, the aim of leading rainwater to enter the ground cannot be fulfilled, the water storage capacity of the ground surface is poor, the evaporation and heat dissipation capacity is obviously reduced, and the heat island effect is strengthened.

Preferably, there are a plurality of vertical through-holes 14 on the stone base permeable bed, because the main function of stone base permeable bed in this kind of panel is to support sand base permeable bed, reduce or avoid sand base permeable bed to receive the shearing force because of top load and/or below stereoplasm frame support, make the size of controlling these vertical through-holes, just can be in the enough little scope because of the shear force control that sets up vertical through-hole and produce, can not lead to the damage of sand base permeable bed, and simultaneously, the weight of stone base permeable bed has been reduced, and, hydroenergy can pass stone base permeable bed smoothly through these vertical through-holes, consequently, allow lower floor (stone base permeable bed and stereoplasm frame) to have bigger thickness, and then have bigger load-carrying capacity.
preferably, the hard frame is provided with vertical protrusions 18 and vertical grooves 19 corresponding to each other on opposite outer sides, and generally, the center of the cross section is a straight line perpendicular to one outer side, and the other outer side through which the straight line passes is opposite to the outer side. When the plate is paved, the adjacent outer side surfaces (corresponding to the opposite outer side surfaces on the same plate) of the adjacent plates are mutually butted, and the vertical protrusions on the corresponding outer side surfaces are inserted into the corresponding vertical grooves, so that the corresponding connecting parts are positioned.
Can be through the vertical protrusion and the vertical recess of pegging graft each other, support out a little clearance 15 (see fig. 6) between the adjacent lateral surface of adjacent panel, for example, the 5 millimeter wide clearance, the corresponding adjacent lateral surface of adjacent panel can not laminate completely after inserting the position, only there is certain laminating region between the vertical protrusion of pegging graft each other and the vertical recess, so that permeate water through this clearance, form stronger water permeability, can suitably control the width in this clearance, avoid bringing inconvenience for people because of the clearance is too big.
In the above case, when a surface water-permeable mat is provided, the area of the surface water-permeable mat may be slightly larger than the area of the main part of the plate material, the edges of the surface water-permeable mat extend from the respective side edges of the respective sand-based perspective layer, and the extension of the surface perspective layer on the adjacent plate material in the direction of the respective outer side face should be just enough to cover the respective gap between the adjacent plate materials, thereby leaving no gap on the surface.
Preferably, the cross sections of the vertical protrusions and the vertical grooves are curved surfaces, for example, the cross sections are approximately semicircular, so that collision and damage during carrying and storage are reduced or avoided.
The technical means disclosed by the invention can be combined arbitrarily to form a plurality of different technical schemes except for special description and the further limitation that one technical means is another technical means.
