Environment-friendly treatment method for silty clay in shield synchronous grouting
The invention relates to a muck resource utilization treatment method, in particular to an environment-friendly treatment method for silty clay in shield synchronous grouting, and belongs to the technical field of geotechnical engineering and tunnel engineering. The method comprises the steps: S1, collecting muck, wherein the muck is silty clay muck; S2, evaluating the pollution; S3, preparing slurry in a laboratory, taking silty clay muck as a basic material of the slurry, adding the silty clay muck into the synchronous grouting slurry to replace a bentonite component in synchronous grouting, and carrying out a uniform experiment; S4, simulating slurry diffusion; S5, establishing a stratum deformation prediction model after slurry solidification by using a neural network; S6, performing regression analysis on the performance and pollution degree of the slurry and the stone body obtained in the S3 and the ground surface settlement obtained in the S5, and determining the optimal proportion of the synchronous grouting slurry base material and the additive. By means of slurry solidification, pollution of heavy metal, inorganic salt and the like caused by the additive added for muck improvement and slurry improvement can be treated, and the treated slurry can meet the pollution control requirement.
本发明是一种渣土资源化利用处理方法，特别是一种粉质粘土在盾构同步注浆中环保处理方法，属于岩土工程及隧道工程技术领域，S1：收集渣土，所述渣土为粉质粘土渣土；S2：评价污染，S3：实验室制备浆液，将粉质粘土渣土作为浆液基本材料，加入至同步注浆浆液中，用以替换同步注浆中的膨润土组分，开展均匀实验，S4：模拟浆液扩散，S5：利用神经网络建立浆液固化后地层变形预测模型，S6：对S3中得到的浆液及结石体性能、污染程度和S5中得到的地表沉降进行回归分析，确定同步注浆浆液基体材料和外加剂最优配比，本发明，通过浆液固化，可处理因渣土改良和浆液改良所加入外加剂引起的重金属、无机盐等污染，使处理后的浆液满足污染控制要求。
