Blocking system and blocking method for tailing-pond flood discharge tower

Abstract

The invention relates to a blocking system and a blocking method for a tailing-pond flood discharge tower. The blocking system comprises a transverse water return pipeline connecting an old tower of the tailing-pond flood discharge tower to a new tower of the tailing-pond flood discharge tower. The blocking system is characterized in that a transverse blocking and grouting pipeline connected with the new tower is arranged in the transverse water return pipeline, a blocking steel plate and a screw rod are arranged at the joint of the old tower and the transverse water return pipeline, water pipeline partitions are arranged in the transverse water return pipeline at intervals of 5-6m, the transverse blocking and grouting pipeline is arranged in the transverse water return pipeline through supports, a C-shaped elbow is connected at a corner joint of a vertical blocking pipeline and the transverse blocking and grouting pipeline through flanges, and a C-shaped elbow is further arranged at the top of the vertical blocking pipeline. The blocking system and the blocking method have the advantages that materials are less prone to blocking pipelines during transporting, blocking efficiency is effectively improved, cost is reduced, and construction period is shortened.

Description

technical field [0001] The invention relates to a plugging system and a plugging method for a tailings pond overflow tower that realizes long-distance transportation of concrete in an environment with a high drop, large vertical and difficult hoisting. Background technique [0002] The role of the tailings pond spillover tower is to build a return water pipeline at the bottom of the tower and carry out long-distance transport of the return water for flood discharge of the tailings pond, and at the same time return the backwater in the pond to the production site through the backwater pumping station for recycle. [0003] Usually, the tailings reservoir uses a spill tower on the backwater system with a service life limit. When the service life is reached, the eyes of the old tower are completely submerged, so that the entire backwater system cannot be controlled, and the water level in the reservoir increases year by year. The current water level in the reservoir is above 14...
