established in 2001 and urgent

With economic development and urban construction, expedite the pace of modern city buildings and gradually surface water blocking materials such as hardening of concrete cover on the formation of the ecology road junket in a large expedience to the people at the same time, the impervious surface to the city environment also brought great negative shock.
as impermeable concrete and asphalt road surface material, making valuable normal precipitation into the ground can not be natural, in appending to the excessive pumping of the groundwater, leadership to the city pile up low water chart, forming a geology on the seawater intrusion; In counting, the impervious surface is difficult to heat and air, water interchange, the lack of urban surface temperature and humidity norm, resulting in meteorology, the the ground surface makes the city the natural growth of factories is difficult,no blocked aisle donot agitate the blood rotation. Its lofty content of minerals, very complicated to make the city green, green high cost; impervious road surfaces to water, reducing the road comfort and safety. When the concentration of rainfall within a short time rain water facilities can only be discharged into the river, addition to the burden of urban drainage facilities.
other reasons as impervious surface due to the sharp decline in groundwater has become increasingly seriously endanger the survival of our environment. In recent years, to the frequent incidence of urban man-made misadventure, we must rouse our vigilance:
following decades of uncontrolled over-exploitation, the prominent Shaanxi consecutive decline of groundwater level in the plain, forming a mammoth funnel, the antique city Xi'an unconsciously annuals of accommodation history of the Big Wild Goose Pagoda is also a 1198 mm, and the west tilt of 886 mm .2000, Xi'an City surface cracks emerged in 4, up to four kilometers wide and 30 cm, causing structural break to many buildings .
known as This, Jinan civic divisions heavily invested 2 billion yuan, citing Huang Baoquan, recharge and recharge to its sometime natural landscape Baiquan spewing, but needs an outer complement our precious water.
Tianjin as the groundwater level The sharp decline, causing salt water intrusion, salt water into the groundwater. To solve the problem of urban water afford in the domestic money in building the 1st water diversion project - problem of the absence of urban water resources, built in 2001 and urgent, cause large and perpetual impact. Some studies have shown .1959 to 1993 in Tianjin, and seawater intrusion due to ground subsidence caused 17.2 billion yuan of direct economic loss, oblique loss of 172.4 billion yuan, a aggregate of 189.6 billion yuan.
airtight The road is difficult to heat and air, water exchange, the lack of urban surface temperature and humidity regulation, resulting in meteorology, the a high concentration of air pollution in the island; impervious surface in the ground made the city the normal growth of plants is difficult, very difficult to make the city green, green high cost;
hardened ground to make rain fall to the city by the sun and rapidly re- evaporation, drying the surface so that the city is more serious. increase the city's dust pollution, the city's humidity varies greatly: quick evaporation of water after rain, air humidity, hot people feel the anguish, and later the exception of the dry. < br> tree growth is the need to exhale and the water, hardening the surface will make the city's trees died due to lack of water or root lodging.
in the summer, hardened floor absorption, storage and reflect solar heat, surface temperature tin rise a few degrees. This ambition addition the city's hot, principally in the modern metropolis of skyscrapers, increased the metropolis paid as the cooling stamina expense.
in the winter, namely lightly hardened ground freezes in the snow, which human peregrination bring a variety of inconvenience alternatively even risky,toronto escorts, merely the difficulty will increase the snow,toronto escorts, when snow can not be added using the groundwater.
water impervious road surfaces to dilute the road solace and safety. < br> When the concentration of rainfall within a short period, the rain water drainage facilities can only be discharged into the river through the city, ponderous rain when the city could easily lead to solemn water, not only increased the burden on urban drainage facilities, and make valuable water resources flow away in vain.
harden the road surface so that rain deposition, this district would reason traffic congestion, increased pollution of vehicle exhaust emissions, on the additional hand, when liquefied in water cross-flow colossal digit of urban pollutants at rain water directly dismissed into the regional pipeline creeks, causing water pollution. and fashioned puddles on the roadside, but too for the summer mosquito breeding places catered.
rapid economic evolution today, in the process of building an international city, the road led to the hardening chain-like negative effect of the urban environment: surface dry, keen decline in groundwater level, surface temperature is high, water blockage, snow, sleek and so on. Therefore, how to solve the city's water problems has transform one international city building major problem. The vicissitudes of life past and present show the truth: there is water in the city, is the everlasting city.
replace orthodox materials with permeable paving materials, road construction has become an international metropolis and successful experience. urban water-permeable surface, so that natural precipitation to infiltrate into the ground directly into groundwater, this train has ancient cities in China, laying on the ground and the traditional courtyard usually secondhand. Therefore, since the nineties in the twentieth century to shirk the laying of impervious surface has been hardened the unity of the world's urban construction and practices. laid the ground is discerned as permeable urban environmental quality, reduce hot flashes, obstruction of floods, water resources and prevent land subsidence reserve an momentous weigh of ecological sustainable development of urban construction and an momentous sign .
as permeable pavement material has many ecological advantages, in the human quest for harmony with nature and maintaining ecological balance and sustainable development thought, Europe, Japan and some other amplified countries, 70 from the last century, began research and development permeable pavement materials, and applied to square, pedestrian street, road sides and the central separation strap, park roads and parking lots, increasing the city's flooding breathable space, urban micro-climate regulation, maintaining ecological balance received a good effect. such as Germany in the early 80s of last century, the seepage road material production has more than 45 million square meters, according to reports, the present and subserve the use of eco-road up to 2,000 million square meters. Japan in the year 1988 reached 500 million square meters construction volume increased year by year since 1996 to approach 863 million square meters, and notwithstanding the impact of the economic downturn in 1998 still reached a volume of 7.19 million square meters of construction. sidewalks and use the square of the total in 1998 to 80 years % or more, accounting for 10% of the lane. At present, foreign materials, mostly concrete quality water seepage, infiltration water is not good, for a better solution to flooding problems in the construction of the road blocks to increase the breach, a gap-type flooding, even the production the grass planting bricks. but this is not only permeable poor results, the gap is also easy to grow weeds. To solve this problem, use of sewage sludge in Japan INAX company, the second firing of ceramic production and permeable paving slabs. permeable paving permeable rate of ceramic high performance, is an ideal surface material. currently in Hokkaido, Japan ceramic permeable paving slabs laid on the sidewalk has reached 25%, 40% of Tokyo would have to change the sidewalk pavement permeable pavement (pervious ceramic .) Taiwan and South Korea and Hong Kong, China permeable paving intend is being implemented.
mandate to defend the survival of the person environment, retain the ecological equilibrium of the surface to solve the above problems, such as by the United States building materials Co., Ltd. Zibo research and development and making of gradient holes permeable ceramic paving tiles, the permeable brick in November 22, 2001 to win the PRC Intellectual Property Office issued a patent certificate, January 11, 2002 by the Ministry of Construction mobilized by the specialists, and obtained the product Even whether the afterward storm, rain can rapidly through the surface, into the ground, can retain the valuable water resources, greatly cultivate the city's nature and alive surroundings. recharge groundwater resources to retain the stability of the urban water table.
as pore gradient ceramic slabs to vein permeability through pore architecture, in the rain, with the surface temperature, stored in the hole under the gradient of permeable sand and grit layers of ceramic slabs of rain will automatically slow evaporation, evaporation of water will sponge heat, lower surface temperature, settled humidity of the air, eliminating the water, hardening of the road will make the city's trees died due to lack of water or root lodging. The gradient porous ceramic slabs hole its agreeable permeability to solve this problem, which is greening the city, particularly the Millennium trees conservation and extremely salutary to the growth of invaluable tree species.
superior environmental protection: pore gradient permeable paving slabs of ceramic waste recycling is not only a fashionable type of environmental protection and ecological construction materials, and its own good environmental protection.
pore gradient pervious paving blocks are ceramic consume ceramics, refractories, cooked industrial waste matters such for coke cortex, spontaneous combustion of coal gangue, waste incineration remnant, urban sewage sludge as raw substances, with its own regeneration, along to the standards of Green Olympics, pore gradient of absorbent paving blocks are standard ceramic green Olympic productions.
gradient of the pore surface of porous ceramic paving tiles is harsh nice amount from repression, was porous honeycomb structure, the brightness hit the road resulting from astigmatism, does not produce the same refraction of ordinary reflective road blocks to prevent the reflected light on the walker eye exposure, protecting people's health.
gradient porous ceramic slabs hole for of its distinctive porous honeycomb structure, can absorb the noise reduce urban noise, to effect the intention of deleting noise.
gradient afterward the rain kept in cavities beneath the permeable sand membrane ceramic paving the rain will automatically slow evaporation, and stability not merely to increase the humidity of the ventilation, and in a way ashore the absorption of automobile exhaust, air purification, reduce conveyance exhaust pollution in urban ventilation.
good security: the gradient porous ceramic slabs hole surface roughness, skid resistance, wear resistance, and Yu Xuetian not product road water, the Pacers will not slip, and discourage night reflective, so that vehicles and pedestrians with a good safety and comfort.
economy and practical: Although permeable pore gradient higher than the price of ceramic slabs of the same type The cement block bricks, but its comprehensive price rebate, with good economy practicality.
laying low cost, porous ceramic pore gradient means for laying paving slabs: the base of the taint compaction is a prime, central storage for the 300mm gravel layer, the upper hole for the dry mart ceramic permeable paving block gradient. The laying cost far less than other shops with watery concrete pavers.
gradient porous ceramic slabs hole because of its high strength, wear resistance, frost fiscal performance, its life is many higher than other types of road blocks. Therefore, the pore gradient ceramic permeable paving slabs with good economic and practical.
gradient porous ceramics as a hole for the road paving slabs laid, the sand layer and pavers can save a lot of water, reducing the city's drainage load. has been tested, per square meter of water permeable sidewalk can be 0.12m3. Thus, even heavy rain, the rain falls on the permeable sidewalk will not efflux, not only can greatly reduce the load on urban drainage and prevent overrunning the city after the storm. Where accessible, permeable pavement can be situated deep wells drilled so quickly recharge underground water may raise the city's water table, and beyond reduce the urban drainage the burden on facilities.
peerless technical performance: pore gradient ceramic permeable paving blocks are manufactured using lofty temperature sintering ceramic materials, extra than any other road material has great technical rendition.
gradient of the permeable ceramic slabs hole is sintered at high temperature, compressive strength g35MPa, flexural strength g3.5MPa. are many higher than the building materials industry, the arranging of the material standards;
As a outcome of the production process of ceramic materials, therefore, pore gradient of permeable paving blocks can be ceramic with a variety of colors, can be laid out aesthetic urban landscape, with anti-fouling nature, rain or high oppression water jets will wash; technical performance surface materials commonly used in China likened
