Lijiang pervious concrete flooring materials

Jing Shi pervious concrete floor, park road coagulation permeable floor. Pervious concrete pavement floor system is a way to make the ground water to be fully absorbed by the floor covering solutions. So that the vegetation has been cast, reducing the need for artificial irrigation, groundwater available to add. This system has a strong practical pavement performance and high environmental value, in line with a stormwater management and water pollution control standards. Ping pervious concrete pavement system to the following features: 1. High water permeability permeable concrete floor has 15% -25% porosity, permeability enables speeds of up to 31.18--51.96 l / m / h, much higher than the most effective rainfall in the best configuration of the drainage discharge rate . 2. Parking environmental protection material flow away is the main organic component itself from the parking lot asphalt binder of hydrocarbons (oil), and this compound is often the environment is contaminated. 3. High bearing capacity of the national testing agencies identified by the carrying capacity of permeable concrete floor is fully capable of carrying standard C30 achieve concrete, higher carrying capacity is generally permeable brick. 4. Good decorative effect permeable concrete floor has a color matching solution that can meet the designer's creativity, different environments and achieve the desired personality style. It is generally difficult to achieve permeable brick. 5. Easy maintenance feared pore clogging is not necessary, the unique permeable pavement systems so that this problem simply by way of high pressure water washing can be resolved. 6. Freeze-thaw resistance permeable pavement systems have more than the average freeze-thaw resistance of concrete pavement capability, will not be broken by the impact of freezing and thawing, because it has a larger pore structure itself. 7. Durability permeable concrete floor wear durable than asphalt, close to ordinary concrete, permeable brick avoid the general existence of a short life span, not economic and other shortcomings. It can live up to 30 years. Permeable paving floor compared to other permeable pavement systems, in addition to the above advantages, they can also reduce your unwanted inputs: 1. Little or no maintenance costs; 2. Reduce or eliminating the need for rain into the pipeline; 3. No other flood control facilities; 4. Simplified pavement and took steps to reduce the funding and construction of the project. In addition, the permeable pavement floor pore structure makes the system unique underground temperatures lower incoming ground, thereby reducing the entire pavement surface temperature. Real life, more and more buildings to reduce people's comfort and increased the scope of thermal stress; severe deterioration in air quality, toxic fumes in the hot air can easily spread, more and more smoke causes more An increasing number of people suffering from respiratory diseases, people are living in danger every day; due to the reduction in the shade, people long exposure to sunlight, the density of the building material itself is low (15-25% of the gap) decreased ground heat storage capacity, greatly increasing the chances of skin cancer. Structural characteristics of permeable concrete permeable paving system allows natural vegetation close to the ground covered in absorbing and heat storage functions, to the maximum extent to solve the problem of people's living environment.
