Anti-seepage mechanism for recoverable unit of rigid hazardous waste landfill
The invention discloses an anti-seepage structure for a recoverable unit of a rigid hazardous waste landfill. The anti-seepage structure comprises a vertical face anti-seepage structure and a bottom anti-seepage structure, wherein the vertical face anti-seepage structure comprises a vertical face reinforced concrete layer, a first HDPE geomembrane layer and a first protective layer which are sequentially arranged from outside to inside, the bottom anti-seepage structure comprises a reinforced concrete bottom plate layer, a second protection layer, a second HDPE geomembrane layer, a third protection layer and a leachate flow guide layer which are sequentially arranged from bottom to top, the bottom of the first HDPE geomembrane layer is connected to the second HDPE geomembrane layer, and the bottom of the first protective layer and the third protection layer are of an integrated structure. According to the anti-seepage mechanism for recoverable unit of the rigid hazardous waste landfill, the resistance of the geotextile protection layer to the acid and alkali of the landfill is effectively enhanced, the use function of the landfill is continued, the maintenance cost is reduced, and the environmental protection and safety problems caused by the leakage of a high-pollution medium are avoided.
本发明公开了一种用于刚性危废填埋场可回取单元的防渗结构，包括立面防渗结构和底部防渗结构；立面防渗结构包括由外向内依次设置的立面钢筋混凝土层、第一HDPE土工膜层和第一保护层；底部防渗结构包括由下向上依次设置的钢筋混凝土底板层、第二保护层、第二HDPE土工膜层、第三保护层和渗滤液导流层；第一HDPE土工膜层底部与第二HDPE土工膜层连接，第一保护层底部与第三保护层为一体式结构。本发明有效增强土工布保护层对填埋物酸碱的抵抗力，延续填埋场使用功能，减少维护成本，避免了高污染介质的渗漏而造成的环保和安全问题。
