Nice permeable floor, cost-effective - to beautify the city Manufacturer: Shanghai hope stone production: China Shanghai Price: negotiable MOQ: 100 m2 Color: choose the model: There are a variety of molds for reference , pervious concrete road base of claim 1, pervious concrete pavement thickness: From the above reasons pervious concrete strength of color, mostly applied to sidewalks, squares, parks, gardens trail, residential roads and other places. Depending on the thickness of the surface layer different applications pavement on sidewalks, bike paths and other light load floor, generally pervious concrete thickness of not less than 8 cm; for car parks, squares and other ground in load floor, permeable concrete thickness of not less than 10 cm. 2, in order to ensure pavement structure layer has sufficient overall strength and permeability, lower surface layer of permeable base and the need for better water retention mat. Substrate requirement: compacted soil layer on the plain, equipped with the base material, the outer strength should be adequate, must have good permeability, using graded gravel or graded gravel and so on. When using graded gravel, gravel maximum particle size should be less than 0.7 times the base thickness and not more than 50mm. Cushion generally use natural gravel, particle size less than 10mm, commonly known as melon seeds, and covered with 15cm ~ 30cm thickness, laying need uniform formation. Second, the construction of the general color pervious concrete as a sidewalk by 8cm standard reference thickness, on this basis, according to different functions, design different thicknesses. 1, pre-construction preparation: pre-construction preparations to do three human, material and technology. (1) Personnel preparation: Construction project to establish a sound organizational personnel structure, tasks to be able to implement the construction project required the principle of staffing should 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 (bonding material, gravel) in construction. Material preparation should be prepared on-site, such as staff accommodation, the required water and electricity supply, construction materials stacked shed (binder requires waterproofing) structures; mixing machine settings venues and a series of preparatory work. Necessary tools (3) construction machinery, carts, bricklayer tools; water and electricity facilities in place, domestic water, electricity and construction with water and electricity. Construction Power: Three-phase electricity, construction of water: ordinary tap water is 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 the objective conditions, according to design requirements, familiar with design drawings, rational arrangement of construction of power, to develop a construction plan, the successful completion of the project and providing technical preparatory work on. 2, Construction: in preparation for full, based on the personnel and equipment before entering the construction. (1) for pervious concrete mixture the consistency of grout in large and small quantity, in order to ensure a uniform grout wrapped in aggregate, should adopt compulsory mixer, mixing time is longer than conventional concrete, as Pervious concrete mix relatively dry and hard before casting, roadbed must be wet with water, due to limited permeability of the concrete mixing water, if roadbed material mixing absorb some of the water, it will accelerate cement setting, reduce the use of pouring in the road, vibration, compaction and seam time, and quickly aggregate loss will weaken the bond strength between. Note: 1) the ratio of the construction site shall be the person responsible for the material. 2) strict control of water-cement ratio, the amount of control that is added to water, the water carved stirring 2 or 3 times to join, does not allow a one-time to join. 3) Stir the material, an appropriate extension of the mechanical stirring time, but not too long. (2) The porous concrete is dry concrete material, its initial setting quickly, usually based on the climatic conditions of the mixture control transit time, transport is generally controlled within 15 minutes, during transport, do not stop, the trolley must be stable. (3) the case of pervious concrete paving casted concrete 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. The mixture evenly on the work surface paving, identify the flatness and control certain degree pan of water, and finally with a spatula smooth, wipe together can not have clear water with scraping feet. Note: 1) loose laying paving material factor is the height above the actual height ratio, according to the pervious concrete dry humidity, generally use between 1.1 and 1.5. 2) Paving as quickly and correctly. 3) due to its high porosity porous concrete, 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. Similarly (4) maintenance pervious concrete and cement concrete properties, the construction of water conservation to be completed the next day, if the weather is hot and dry in 8 hours after pouring sprinkler maintenance, at least twice a day, curing time of less than three days. But direct shower water spray 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 and dried in about 3 days, brushing or spraying transparent brightener, enhanced durability and aesthetics. It takes too long to prevent the pores of porous concrete so that contamination and clogging. Construction process is as follows: Materials prepared by stirring transport unloading paving screed compaction received light curing cutting seam brushing brightener five, quality assurance and maintenance services company so construction floor implement 1--2 years of free maintenance (anthropogenic except for destruction). After over maintenance period, the company will charge for the cost of labor, materials and manufacturers for long-term service.
