Method for preparing low-strength material from pipe jacking waste muck and flexible pipelinebackfilling method
The invention relates to the technical field of trenchless pipe jacking engineering, in particular to a method for preparing a low-strength material from pipe jacking waste muck and a flexible pipeline backfilling method. The method specifically comprises the following steps: S1, respectively weighing quantitative muck, a gel material, a water reducing agent and water; wherein the mass of the gelmaterial is 1/5-3/10 of the mass of the muck, the mass of the water reducing agent is 1/6-1/5 of the total mass of the gel material and the muck, and the mass of the water is 1/4-19/50 of the total mass of the gel material and the muck; and S2, uniformly stirring the muck, the gel material and the water weighed in the step S1, adding the water reducing agent, continuously stirring until the mixture is uniform, and standing the obtained mixture for 15-20 minutes to obtain the low-strength material. The raw materials for preparing the low-strength material are wide in adaptability and easy to obtain, waste gas muck on a pipe jacking construction site is efficiently and reasonably utilized, the environmental protection property is high, the muck conveying cost is reduced, and the engineeringconstruction cost is greatly reduced.
本发明涉及非开挖顶管工程技术领域，尤其涉及一种利用顶管废弃渣土制备低强度材料及柔性管道回填方法，其具体包括以下步骤：S1、分别称取定量的渣土、凝胶材料、减水剂和水；其中，凝胶材料的质量为渣土质量的1/5～3/10，减水剂的质量为凝胶材料与渣土总质量的1/6～1/5，水的质量为凝胶材料与渣土总质量的1/4～19/50；S2、先将S1中称取的渣土、凝胶材料和水搅拌均匀后，加入减水剂继续搅拌至均匀，将得到的混合物静置15～20min后，即可得到所述低强度材料。本发明制备低强度材料的原料适应性广泛易取得，且高效合理的利用了顶管施工现场的废气渣土，环保性强，还减少了运送渣土的费用，大大降低了工程的施工成本。
