Treatment method of sandstone stratum pipe jacking waste muck
The invention discloses a treatment method of sandstone stratum pipe-jacking waste muck, which comprises the following steps: uniformly mixing the sandstone stratum pipe-jacking waste muck, cement, fly ash, mineral powder and water, adding an additive, uniformly stirring, and standing for 20-30 minutes to obtain a controllable low-strength material; wherein the weight parts of the sandstone stratum pipe jacking waste muck, the cement, the fly ash, the mineral powder, the additive and the water are 2500 to 2700 parts, 300 to 340 parts, 180 to 220 parts, 70 to 90 parts, 4 to 8 parts and 800 to 900 parts respectively. As other substances such as asphalt need to be paved on the controllable low-strength material, the sandstone stratum pipe-jacking waste muck is sealed, physical and chemical reactions caused by exposure of the sandstone stratum pipe-jacking waste muck in air for a long time and pollution to soil are avoided, waste of land resources can also be avoided, and it can be known that the sandstone stratum pipe-jacking waste muck can be recycled. The treatment method is green and environment-friendly.
本发明公开了一种砂岩地层顶管废弃渣土的处理方法，将所述砂岩地层顶管废弃渣土、水泥、粉煤灰、矿粉以及水混合均匀后加入外加剂搅拌均匀后静置20～30分钟，得到可控低强度材料；其中：所述砂岩地层顶管废弃渣土、水泥、粉煤灰、矿粉、外加剂以及水的重量份分别为2500～2700份、300～340份、180～220份、70～90份、4～8份以及800～900份。砂岩地层顶管废弃渣土被固封起来(因为在可控低强度材料上面还需要铺装其它物质，如沥青)，避免了砂岩地层顶管废弃渣土长时间暴露空气中发生的物理化学反应，对土壤造成的污染，还可以避免土地资源的浪费，由此可知，该处理方法绿色环保。
