Long-term production, permeable flooring materials direct to the provinces, permeable floor construction, construction engineering price, flooding the floor around the country to undertake construction projects. Permeable floor, also known as pervious concrete, floor seepage, drainage concrete, permeable ground ecology, color and so on permeable ground. Shanghai Hope Stone Landscape Engineering Co., Ltd., is permeable floor (pervious concrete) professional manufacturer, the company specializing in the production of permeable floor (seepage floor) in a number of large sites in several provinces of the country widely used (for example: Shanghai Chongming Dongtan Wetland Park), quality and price generally appreciated by customers, specifically to inquire, permeable pervious concrete floor Product Description: pervious concrete (concrete permeable colorful floor, flooding the floor), mainly by stone and a half stone beans and other standard stone, high-grade cement, gel enhancer, emulsification, coloring pigments, stabilizers and penetration protection, and water and other materials cured together constitute. First, the pervious concrete composition of the material: eco-permeable concrete constituent materials: special binder, gravel, water. Details are as follows: (1) special binder permeable floor. Manufacturers hope stone production of a special cement, which is a high strength grade Portland cement-based materials, which together with a variety of additives to increase the strength and cohesion of the powdery material composition, and user requirements adding inorganic pigments weather so and gravel, water, mixed by a certain percentage, the composition of the different colors of pervious concrete pavement. (2) gravel. Permeable gravel floor used should have high technical requirements. Permeable floor, in order to save costs, generally stratified design, that plain colored surface layer + grassroots. Colored surface layer thickness is typically 3-4cm; stones that used stone-meter diameter of about 4-6mm. Plain base thickness is generally based on carrying capacity to design, the use of stones that pisolite, commonly known as melon slices; diameter of about 10-30mm. (3) water. You can use ordinary tap water. Usually at the end of cloudiness filtered groundwater or used dirty water, can not be used. Permeable floor (pervious concrete) Technical parameters: Specifications pervious concrete into Mixture indicators and hardened concrete indicators 1. Mixture: Slump (5mm-50mm); setting time (initial setting less than 2h) ; slurry wrap degree (wrapped in uniform, hands clenched into a group, with a metallic sheen). 2. hardened concrete: strength (C15-C30); permeability (not less than 1mm / s); porosity (10% -20%) 3. Anti-freeze-thaw cycles: no less than D100 pervious concrete pavement construction practices: Different carrying tonnage, thickness of the layers list pervious concrete pavement layers tonnage T Thickness (mm) surface layer of cushion grassroots prime soil compaction 24,080,150 compaction factor> 0.93 5,408,030,084,014,030,013 40 180 300 II. eco-permeable floor (pervious concrete floor) Performance and advantages: 1, absorb noise generated when driving the vehicle, creating a quiet and comfortable living environment and transportation; 2, rainy night to prevent surface water and pavement reflectors, improved vehicle , pedestrian traffic comfort and safety; 3, increasing urban water permeable, breathable area, strengthening heat and moisture exchanger surface and air, regulating urban climate, reduce surface temperature, will help alleviate the urban "heat island phenomenon"; 4, it can increase the infiltration of surface rainwater, groundwater level to alleviate environmental problems, such as a sharp decline in some cities. 5, pervious concrete floor integrity, long life, similar to the life of ordinary concrete; at the same time to make up for the integrity of permeable brick poor, rugged, easy to loose, short life cycle and other issues. 6, permeable concrete floor has a series of classic color matching solution that can meet the special requirements of the designer's creativity and owners to achieve different environments, different style and personality requirements of decorative ideas, other materials can not match the ground. Pervious concrete ground floor suitable for municipal areas, gardens, parks, sidewalks, sports stadiums, parking lots, residential, commercial plaza and cultural facilities such as the ideal choice of three ecological permeable floor (concrete permeable floor) construction general press 8cm sidewalk as a reference standard thickness, on this basis, according to different functions, the design of different thickness. 1, pre-construction preparation: Before construction personnel prepare to do three, material, technology. (1) personnel preparation: establish and improve construction project organization's staff set the task to be able to realize the construction project required the principle of staffing must be strictly controlled. (2) material preparation: Pervious concrete is similar to ordinary concrete, the raw material in less sand, gravel and a certain size to replace the aggregate, have a certain amount of material (binder, gravel) in construction. Material preparation should be prepared on-site, such as staff accommodation, the required water and electricity supply, construction materials piled shed (binder requires waterproofing) structures; mixing machinery is set site and a series of preparatory work. Necessary tools (3) construction machinery, carts, bricklaying tools; hydroelectric facilities in place, domestic water, electricity and construction with water and electricity. Construction of electricity: three-phase power, construction of water: ordinary tap connected to the next mixing equipment. (4) technical preparation before construction: to understand and analyze the characteristics of the project, schedule requirements, understand the construction of objective conditions, according to the design requirements, be familiar with the design drawings, construction layout reasonable force to develop a construction plan for the successful completion of the project and providing technical preparatory work on. 2. Construction: In the preparatory work on the basis of full, personnel and equipment before entering the construction. (1) pervious concrete mixture stirred slurry consistency in large and small quantities, in order to make the grout to ensure uniform wrapped in aggregate, should adopt compulsory mixer, mixing time is longer than conventional concrete, due to pervious concrete mixture relatively dry and hard before casting, roadbed must be moistened with water, because of the limited amount of water permeable concrete mixing, if the roadbed material absorbs some of mixing water, it will accelerate cement setting, reduce the use of Pouring on the road, vibration, compaction and seams of time, and rapid water loss will weaken the bond strength between the aggregate. Note: 1) the ratio of the construction site shall be the person responsible for the material. 2) strictly control water-cement ratio, the amount of control that is added water, the water in the equatorial 2 to 3 times with stirring was added, was added in one are not allowed. 3) To make the material stir, an appropriate extension of mechanical agitation time, but not too long. (2) Transportation pervious concrete is dry concrete material, its initial setting fast, generally based on a mixture of weather conditions to control the transit time, transport is generally controlled within 15 minutes, during transport, do not stop, the trolley must be stable. (3) pervious concrete paving casted concrete case of dry material, its initial setting quickly, paving must be timely. For pavement surface, large-scale construction using sub-positions paving the way, the song spread factor of 1.1. Paving mixture evenly on the work surface, identify the flatness and control certain degree pan of water, and finally with a spatula smooth, wipe out the water together with a doctor can not have feet. Note: 1) loose laying paving material factor is the ratio of the height above the actual height, according to pervious concrete dry humidity, generally use between 1.1 to 1.5. 2) When the paving as quickly and correctly. 3) due to its pervious concrete porosity, water loss quickly, when the weather temperature is above 35 ° C, the construction time should be advised to avoid the midday, in the morning and evening for construction. Similar to (4) maintenance pervious concrete and cement concrete properties, after construction is completed the next day to water conservation, if the weather is hot and dry in 8 hours after pouring sprinkler maintenance, at least twice a day, at least three days curing time. But direct water spray shower water of the concrete surface should be directed from the top down pressure water spray should not be used. 3, brushing transparent brightener: concrete surface to be molded in three days or so after drying, brushing or spraying transparent brightener, enhanced durability and aesthetics. Prevent too long to make pervious concrete pore clogging contaminated. Construction process is as follows: Material prepared by stirring transport unloaded paving leveling compaction received light curing cut four slits brushing brightener, quality assurance and maintenance services company in the construction of the floor so that the implementation of 1-2 years of free maintenance (anthropogenic except for damage). After over maintenance period, the company will be charged for the cost of labor, materials and manufacturers of long-term service.
