本文介绍了充填袋(内装就地取吹填的淤泥土w≥100%)的两种用途,其一是在淤泥土上修筑子埝后进行二次吹填至要求的高程,降低主围埝的工程量,从而降低工程造价;其二是在吹填土上进行地基处理时采用充填袋作为施工设备的工作垫层,可替代常用荆芭等材料,且有好的经济效益。本文还针对真空预压时射流泵既抽真空又抽水的问题,提出增加抽水设备的建议,使得射流泵和抽水设备分工明确,提高工程的节能效益和经济效益。
In this paper, two applications of filling bags (w≥100%) are described. One is to perform secondary filling to the required elevation after sub-construction of the silt, Of the project, thereby reducing the cost of the project; the second is used in the filling of the ground when the filling bags used as a working equipment cushion, can replace the commonly used Jingba and other materials, and have good economic benefits. In this paper, aiming at the problem of vacuum pump and pumping in jet pump under vacuum preloading, the suggestion of adding pumping equipment is put forward, which makes the division of jet pump and pumping equipment clear and improves the energy saving and economic benefits of the project.
