A vacuum pre-pressing dehydration system and implementation method for superfine tailings filling tube bag

Abstract

The invention discloses an ultrafine tailings filling bag vacuum preloading dehydration system and a dam construction implementation method. The ultrafine tailings filling bag vacuum preloading system includes a geotechnical pipe bag, a mobile vacuum preloading integrated equipment module, PVC drainage soft belt and power supply module, which can realize the functions of slot dialysis, surface bonding, vacuum cover suction, filter sand drainage, manual movement, water gas replacement, liquid level automatic control, automatic drainage and flexible transportation, etc. Filling pipe bag dams with ultra-fine tailings in reservoirs provides a mechanized, efficient and flexible low-cost solution. Due to the high cost of materials and the lack of dam construction technology, on the premise of continuing to apply domestic flat geotechnical pipe bags, the technical bottleneck of ultra-fine tailings filling pipe bag dehydration is broken, and the construction technology of pipe bag dam construction technology in tailings Provide technical support for further promotion and application in the engineering field.

Description

technical field [0001] The invention relates to the technical field of engineering pipe bag dam building, in particular to a vacuum preloading dehydration system and an implementation method for superfine tailings filling pipe bags. Background technique [0002] Geotechnical tube bag is a very suitable technology for rapid dehydration and consolidation of fine particles. The technical principle is to fill a large amount of slurry with high water content in the tube bag, and quickly and effectively discharge water and retain the slurry under the internal pressure of the tube bag. solid particles in the body. The advantages of tube bag technology are large processing capacity, small footprint, safety and environmental protection, low disposal cost and simple technical process. Since the introduction of geotechnical pipe bags from the water conservancy industry into the field of tailings engineering in 2010, it has realized fine-grained tailings pipe bag dams with a particle c...
