    With the progress of social development and construction technology, the national awareness of environmental protection is getting stronger and stronger, we all want the city a little more green, but due to the shortage of land resources, which is also the reason for the renovation and renovation of existing roofs.growing number of planted roofs and the variety of vegetation layers on them. How to design to ensure that the roof of the beautiful and drip-drip?design of waterproof roofing
    first of all, according to the owner's idea of housing cultivation, the roof carrying capacity is calculated
    China
    . Then according to the local climate environment according to local conditions to consider impermeability, drainage, anti-root system, and then combined with the local climate to determine the planting soil and vegetation. The design of the planting roof is based on the basic provisions of the Planting Roof Technical Regulations (JGJ155-2007), which are in accordance with the principles of anti-draining storage and weight, safety, environmental protection, energy conservation, economy and local conditions, and take into account the requirements of the construction environment and process.roof structure level from bottom to top is:
    1. Structure layer
    2.2mm thick BCS-231 solvent-based rubber asphalt waterproof coating
    3.4mm thick root-resistant puncture waterproof coil
    4.5mm thick reinforced fine stone concrete protective layer
    5.hydrophobic plate
    6.filter layer
    7.planting soil waterproof layer construction points granation treatment demolition of the original roof of the various structural levels, up to the structural plate. Remove the garbage, use a grinder to polish the base surface, and then blow away the dust.brush BCS-231 solvent-based rubber asphalt waterproof coatingIt is required that the scraping thickness is uniform and there is no leakage. Where cracks appear in the roof structure plate, the BCS-231 solvent-based rubber asphalt waterproof coating is applied along the seam, the brush width is 150mm, and the glass fiber cloth is used to strengthen. Pipe root, rainwater mouth and other node parts of the first 20mm×20 inserted waterproof seal paste treatment, and then the use of BCS-231 solvent-based rubber asphalt waterproof paint for painting, paste glass fiber cloth for enhanced treatment. Yin and Yang angle using BCS-231 solvent-based rubber asphalt waterproof coating for painting, glass fiber cloth for enhanced treatment.coilsusing ARC polymer modified asphalt root-resistant puncture waterproof coils thick 4mm II.TYPE PE membrane ARC-701 chemical blocking root. Take the hot melt method to cover the ARC polymer modified asphalt root-resistant puncture waterproof coil layer. Requires coil bonding no empty drum, coil bonding width of 100mm and extruded asphalt strip, no bonding bad phenomenon.water storage24-hour water storage and rain shower test, no leakage to carry out the next process construction.Reinforced concrete protective layerpoured 50mm thick C25 fine stone concrete rigid protective layer, built-in single layer of steel mesh (separated at the seams), according to 6x6m to leave a vertical and horizontal separation seam, seam width of 20mm, seams embedded with waterproof sealing material. Slope to the storm drain, slope 2%.Hydrophobic plate when laying H20 hydrophobic plate round platform up, long edge tie: tie 1-2 fulcums;20cm20cm of earth cloth, which is 20cm higher than the height of the soil being planted.the choice of planting
    medium1.  The selection of cultivated land is not only rich in organic rotting plants and nitrogen and phosphorus potassium nutrients, but also has a good granulation structure.
    2.  Doping 1/3 sawn wood powder in cultivated land can not only reduce self-weight, but also fill the gap between the soil grain structure of cultivated land, which is conducive to water absorption, discharge and supply of medium oxygen replacement, no water accumulation, and does not harm the development of plant system.
    3.  Depending on the variety of green plants, the thickness of the planting layer is different and is adjusted between 20-40cm.
    4.  A moderate amount of fermented farm fertilizer is added to the soil before planting. After planting can be based on the form of plant growth, sowing Chinese medicine residue or "bean cake" (soybean oil residue), after watering or rain inside the nutrients are absorbed by the plant, the plant grows rapidly. vegetation layer you can grow small shrubs, grass, vegetables, and climbing vines and other plants, depending on the season, different preferences, you can choose any choice. when is plentiful, plants do not need to provide additional water, and in dry and rainy seasons they can be replenished with plastic pipes with "lotus heads". advantages of growing roofs
    insulation roofs covered with green plants, summer summer, winter warmth, with good insulation effect, reduce energy consumption, improve the city's heat island effect. reduction plants absorb carbon dioxide, release oxygen through photoynalysal use, increase the environmental oxygen content, is an effective cost-effective emission reduction measures to purify the air. Eal economic benefits covering more than 20 cm of planting soil and covering the roof of green plants, can meet the requirements of roof insulation insulation, that is to say, save the insulation layer, so as to create low maintenance costs; Social benefits Planting roofs can relieve atmospheric ups and downs, reduce urban noise, help relieve urban drainage loads (sponge roofs) during heavy rains and rainstorms, beautify roofs, improve the city's environmental outlook, improve the quality of people's living and working environments, and have good social benefits.
