Description
Technical field
The present invention relates to a kind of waterproof of building planting technique roofing, anti-plant root puncture concrete structure and construction method thereof.
Background technology
So-called planting technique roofing, refers to building roof (comprise roof, balcony, balcony etc.) or the underground building top board of paving with planting soil planting plants.Planting technique roofing is to improve urban green coverage, slow down " heat island effect ", reduce atmosphere pollution, save the energy, extend waterproofing course application life, improve the ecological environment and the effective way of beautifying city view.But at present in China, planting technique roofing is not widelyd popularize, its main cause is in anti-root puncture, waterproofing work, still to have technical difficulty.Planting plants on roofing, the water source that roofing faces is more, and also more complicated of environment of living in, particularly because the root system of plant has very strong penetration capacity, can damage effect to the water-proof function of roofing.Planting technique roofing is generally on traditional roofing flexible waterproof layer, sets up one deck rigid course, by the good flexible waterproof layer of water resistance and firm rigid protection layer compound use.
Flexible waterproof layer generally adopts polymer modified asphalt waterproof roll or polymer membranes.Because containing Plants affinant matter a---protease in pitch, this kind of material is a kind of nutriment to plant, when root system of plant approaches after this kind of material, root system can penetrate pitch and absorb this composition, result causes adopting the planted roof of polymer modified asphalt waterproofing course, root system of plant First Year has just penetrated waterproofing course, the destruction of next just having caused waterproofing system in the very short time.Polymer membranes does not contain affinant-protease of plant, plant can active attack waterproofing system, but, all root systems of plant have same growth characteristics-hydrotropism and downward property, the pressure that penetrates of root system of plant is huge, little grass and little tree can grow vigorously and be clear proof in the gap of rock, experimental results show that polymer membranes also can be destroyed by root system of plant in 1～2 year.Rigid course generally adopts cement mortar or pea gravel concreten making; but cement mortar and concrete are all fragile materials of heterogeneous body porous; its inside exists a large amount of holes; expanded with heat and contract with cold and structural stress etc. affects and is prone to crack; once cement mortar or the infiltration of pea gravel concreten cracking, root system of plant can inwardly be grown along crack, like this; the flexible waterproof material of rigid course below will suffer the destruction of root system of plant, cause planted roof seepage.
For improving the damage capability of the anti-root system of plant of flexible waterproof layer, patent CN200920097701.6 has proposed a kind of planted roof self-adhesion root resistant waterproof roll, this coiled material is by lower barrier film, anti-type self-adhesion glued membrane of lower painting, root resistant waterproof roll, anti-type self-adhesion glued membrane of upper painting and upper barrier film be order composition from the bottom to top, adopt polyethylene barrier film, polyester insulating film, polyvinyl chloride barrier film, polypropylene barrier film, nylon barrier film, one in silicone oil paper film is as upper, lower barrier film, root resistant waterproof roll is metal tire base (pewter, complex copper tire base, Copper Foil tire, aluminium tire) waterproof roll, SBS or APP modified bitumen root resistant waterproof roll, one in root-resistant puncturing polyethylene tire polymer modified bituminous waterproof sheet material and root-resistant puncturing polyvinyl composite water-proof coiled material.Patent CN201120019958.7 has proposed a kind of ethylene propylene diene single-face composite root puncture resistant waterproof roll, adopt compound making sheet technology, comprise Ethylene Propylene Terpolymer waterproofing course and lower Ethylene Propylene Terpolymer waterproofing course, sandwich aluminium tire base between upper and lower Ethylene Propylene Terpolymer waterproofing course, lower Ethylene Propylene Terpolymer waterproofing course outside is for strengthening terylene non-woven fabric; Upper and lower Ethylene Propylene Terpolymer waterproofing course and aluminium tire base composition Ethylene Propylene Terpolymer aluminium tire base waterproofing course; Ethylene-propylene-diene monomer glue-line adds plasticizing agent in polymerization process.Though these flexible waterproof sheets have the good puncture resistance of resistance to root system of plant, material cost and processing charges increase substantially, and cause expensively, have seriously limited it and have applied.
