Dredged sludge curing material and pipeline curing and hydraulic reclamation method
The invention discloses a dredged sludge curing material and a pipeline curing and hydraulic filling method, the curing material comprises the following components in percentage by weight: 5-18% of sea sand, 0.02-0.08% of an anti-erosion hydraulic cementing material, 0.02-0.08% of a dispersing material, 4-8% of an early strength material and 4-8% of a precipitation material, the dispersing material accounts for 1-4% of the mass of the anti-erosion hydraulic cementing material, the early strength material accounts for 0.5-2% of the mass of the anti-erosion hydraulic cementing material, and the precipitation material accounts for 5-12% of the mass of the anti-erosion hydraulic cementing material. Through strong stirring equipment such as the spiral stirrer, the stirring barrel and the stirring mixer in the conveying process, it can be ensured that various curing materials and the dredged sludge are uniformly stirred, and the curing strength of the dredged sludge is improved. The dredged sludge is generated in a marine environment, the concentration of sulfate ions is high, cracking and expansion of a solidified foundation soil body are reduced by adding an anti-erosion hydraulic cementing material in the pipeline conveying process, the structural stability is high, and the durability is high.
本发明公开了一种疏浚淤泥固化材料以及管道固化吹填方法，固化材料由海砂、减阻材料、抗侵蚀水硬胶凝材料、分散材料、早强材料和降水材料组成，其中海砂、减阻材料和抗侵蚀水硬胶凝材料按照重量比分别为疏浚淤泥质量的5‑18%、0.02‑0.08%和4‑8%，分散材料、早强材料和降水材料分别为抗侵蚀水硬胶凝材料质量的1‑4%、0.5‑2%和5‑12%。本发明通过输送过程中的螺旋搅拌机、搅拌桶和搅拌混料机等强力搅拌设备，能确保各种固化材料与疏浚淤泥搅拌均匀，提高疏浚淤泥的固化强度。疏浚淤泥产生于海洋环境，硫酸根离子浓度高，通过在的管道输送过程中添加抗侵蚀水硬胶凝材料，降低固化后基础土体的开裂和膨胀，结构稳定性高，耐久性强。
