Environment-friendly mud discharge field sludge rapid consolidation system and consolidation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of river channel dredging and silt comprehensive treatment engineering, in particular to an environment-friendly sludge rapid consolidation system and a consolidation method in a sludge discharge field. Background technique [0002] In order to improve the water quality of rivers and lakes and ensure the normal function of river flood discharge and navigation, it is necessary to carry out large-scale comprehensive dredging and dredging projects for waters such as rivers and lakes, usually by means of suction, pumping or hydraulic excavation The silt is disturbed into a mud state by means of a pump, and then pumped to the planned sludge discharge field. The amount of dredging work is generally large, and the amount of silt and spoil in the mud discharge field can reach tens of millions of square meters. Compared with normal silt, the dredged silt consolidation of the sludge discharge field has the following ...
