Anti-seepage water stopping method for refuse landfill

The invention relates to an anti-seepage water stopping method for a refuse landfill. The method comprises the following steps that 1, viscidity soil and a geotechnical protection layer (1) are beddedand compacted, and an induction arcing and grouting device is arranged above the viscous soil and the geotechnical protection layer; 2, anti-seepage geomembrane (4) is laid above the induction arching and grouting device; and 3, after being subjected to thermal expansion and arching by solar radiation, the anti-seepage geomembrane (4) perform grouting on the induction arching and grouting device.Compared with the prior art, the anti-seepage water stopping method has the advantages of being rapidly applied, small in work amount, low in cost and good in water stopping effect. 本发明涉及种用于垃圾填埋场的防渗止水方法，该方法包括如下步骤：(1)铺垫压实粘性土及土工保护层(1)，在粘性土及土工保护层(1)上方设置诱导起拱注浆装置；(2)在诱导起拱注浆装置上方铺设防渗土工膜(4)；(3)待防渗土工膜(4)接受太阳辐射受热膨胀起拱后向诱导起拱注浆装置中注浆。与现有技术相比，本发明能够快速应用，并且工程量小，成本低，止水效果好。
