A tailings dam silting negative pressure drainage reinforcement device

Abstract

The invention provides a tailing dam clogging negative pressure seepage discharging reinforcement device, and belongs to the technical field of a tailing pond auxiliary device. The tailing dam clogging negative pressure seepage discharging reinforcement device comprises a water collection drill bit, a connecting threaded pipe, a metal net filtering pipe, a geotextile, a laminating film, a steam extraction pipe, a threaded clamp pipe cover, a negative pressure pump, a pressure gauge, an emergent grouting pump and a gas liquid separation container, wherein the water collection drill bit and themetal net filtering pipe are in segmented connection through the connecting threaded pipe; the metal net filtering pipe is tightly wrapped by the geotextile and is vertically pressed into tailing sand; the steam extraction pipe is put into the water collection drill bit; and the threaded clamp pipe cover and the metal net filtering pipe are connected in a sealed way for opening sealing. The tailing dam clogging negative pressure seepage discharging reinforcement device has the advantages that the problem of seepage discharging and clogging phenomena in different positions of a high-risk dam body can be effectively solved; the seepage line of the dam body is lowered; by aiming at the conditions such as extreme weather and geology, the stability of the damage body is improved through the reinforcement via internal grouting and through the reinforced surface on the ground surface by steel bars; the operation risk of the tailing dam is effectively reduced; and meanwhile, the reinforcementdevice can also be used for slope reinforcement in regions with rainfall precipitation, leaching mining and the like.

Description

technical field [0001] The invention relates to the technical field of tailings dam auxiliary devices, in particular to a tailings dam silting negative pressure seepage drainage reinforcement device. Background technique [0002] Tailings pond dam breaks and side slope landslides are major hazards that restrict safe production. In the past ten years, the production scale of my country's mining enterprises has expanded, and the discharge of tailings has increased. However, due to the backwardness of technology and management, the risk of tailings ponds has gradually emerged, and some tailings ponds have even become major hazards, such as extreme environments such as heavy rain and earthquake liquefaction. Once the tailings pond breaks, the consequences will be disastrous; rainy areas The long and narrow road slopes and traffic fortresses, etc., have taken many treatment methods, but the effect is not good. The main reason is that the earthwork is oversaturated due to extreme...
