Environment-friendly mud discharge field sludge rapid consolidation system and consolidation method thereof
The invention discloses an environment-friendly mud discharge field sludge rapid consolidation system and a consolidation method thereof . The specific working principle of the consolidation method for using the environment-friendly mud discharge field sludge rapid consolidation system comprises the following steps that grouting floral pipes of an external binding mold bag is implanted into a muddischarge field foundation, vertical drainage pipes are implanted around the grouting floral pipes, and the elevation of the grouting floral pipes and drain pipe hole openings is higher than the elevation of the sludge stacking surface; after sludge is discharged and completed, the sludge slurry is sequentially poured from the grouting floral pipes of boundary rows according to sequence, the perfusion pressure is increased step by step, the mold bag slowly expands to a designed diameter, and the sludge is extruded radially; the slurry in the mold bag is quickly consolidated under the action ofpressure, the free water of the slurry in the mold bag and the super-static pore water generated by extrusion of the sludge are discharged from an earth ground together through the vertical drainagepipes, and the free water and the super-static pore water are gathered into horizontal drainage pipes to be discharged out of the field to achieve rapid consolidation. The method overcomes the problems that a traditional sludge consolidation method is long in consolidation time, complex in process, high in auxiliary measure requirement, difficult in subsequent cleaning work, poor in economy, poorin environmental protection property and the like, and has the characteristics of short consolidation time, high environmental friendliness, simple equipment and process and low construction cost.
一种环保型排泥场淤泥快速固结系统及固结方法，具体为将外部绑扎模袋的注浆花管植入排泥场地基中，管周围植入竖向排水管，注浆花管及排水管孔口高程高于淤泥堆放表面高程；淤泥排放完成后，从边界排注浆花管开始，按照排序依次灌注淤泥浆液，灌注压力逐级升高，模袋慢慢膨胀至设计直径，径向挤压淤泥；模袋内泥浆在压力作用下快速固结，模袋内泥浆的自由水与淤泥受挤压产生的超静孔隙水一起通过竖向排水管排出地表，汇入水平排水管排至场外，实现快速固结。本申请克服了传统淤泥固结方法固结时间长、工艺复杂、辅助措施要求高、后续清理工作困难、经济性和环保性差等问题，具有固结时间短、环保性高、设备及工艺简单、施工成本低的特点。
