摘要
文章讨论了化学灌浆在威海市垃圾处理厂截污坝防渗帷幕中的应用及效果。截污坝是垃圾处理厂的主要部分,其防渗能力直接关系工程的优劣。采用水泥灌浆后所做的压水试验证明,岩土的渗透性能虽然得到改善,但是达不到设计要求。尔后通过中间夹单排化学灌浆补强的布孔形式改进了施工工艺,进行了防渗的再处理。结果表明,结合化学灌浆后大大提高了岩体的防渗能力,效果明显,达到了设计要求。
This paper discusses the application and effect of chemical grouting in seepage proof curtain of interception--pollutant dam of Weihai waste treatment plant. Interception pollutant dam is the main part of waste treatment plant, and its seepage capabilities di- rectly influence the effect of engineering construction. The water pressure test after adop- ting cement grouting proves, although the permeability of rock improves, it can not achieve the design requirement. Then by reinforcing the chemical grouting by means of clipping single row in middle, this bunch hole patterns improve construction technology and treats the seepage again. The result indicates that the seepage capability of rocks increases greatly associating with chemical grouting.
