關(guān)于排水板與HDPE土工膜組合防排水系統(tǒng)在北京第十四中學(xué)屋頂綠化工程的設(shè)計與施工,首先要了解材料的特點,才能發(fā)揮材料的作用。排水板是由高密度聚乙烯制成,具有排水功能,適用于大型廣場綠化、車庫頂板綠化等工程。有良好的隔水、隔熱、強度高、柔性好、防潮性能;HDPE土工膜也被稱為“高密度聚乙烯土工膜”,具有優(yōu)良的耐環(huán)境應(yīng)力開裂性能,抗低溫、抗老化、耐腐蝕性能,以及較大的使用溫度范圍(-60--+60)和較長的使用壽命 (70年),廣泛使用在車庫屋頂隔根層、垃圾填埋場防滲,人工湖防滲,尾礦處理等防滲工程。
北京市第十四中學(xué)屋面綠化工程在原屋面基礎(chǔ)上,選用聚乙烯丙綸雙面復(fù)合防水卷材作為普通防水層、1.5mm厚HDPE土工膜作為耐根穿刺防水層、2cm厚HDPE蓄排水板作為排水層,形成一個防滲、隔根、排水的系統(tǒng),并且隔根層的HDPE土工膜本身也具有非常強的防滲性能,所以整個屋頂綠化采用了雙道柔性防水加排水的設(shè)計,這樣的施工效果好,并種植根淺、易生長養(yǎng)護(hù)的植物形成種植屋面。該屋面荷載未超標(biāo),關(guān)鍵節(jié)點防水阻根效果好,排水通暢,景觀效果佳,被評為北京市2011年度園林綠化工程。具體技術(shù)方案可以來郵咨詢:13505480586@163.com.
On the combination of drainage plate and HDPE geotechnical membrane waterproof and drainage system in the design and construction of the fourteenth middle school in Beijing roof greening projects, we must first understand the characteristics of materials, to maximize the role of material. Drainage plate is made of high density polyethylene, with drainage function, suitable for large green square, the garage roof greening engineering. Good waterproof, heat insulation, high strength, good flexibility, moisture-proof performance; HDPE geotechnical membrane has also been called the "high density polyethylene geomembrane", which has excellent resistance to environmental stress cracking resistance, low temperature resistance, aging resistance, corrosion resistance, and large temperature range (-60--+60) use life and long (70 years), widely used in the garage roof root separation layer, landfill, the artificial lake seepage, seepage engineering tailings disposal etc..
