Method for burying drainage-seepage body of reverse filtering pipe in tailing dam

Abstract

The invention discloses a method for burying a drainage-seepage body of a reverse filtering pipe in a tailing dam. The method comprises the steps that buried water guide pipes are implanted to a tailing dam body from top to bottom; water collecting pipe grooves are formed in the tailing dam body parallel to a fill dam in an excavating mode and water collecting pipes are buried in the water collecting pipe grooves in a sectionalized mode; drainage-seepage pipe grooves are excavated along the natural gradient of a dry beach of a tailing pond and water seepage pipes are placed inside the drainage-seepage pipe grooves; the water seepage pipes are connected with the water collecting pipes and the water guide pipes are connected with the water collecting pipes. According to the method, the burying mode of the reverse drainage-seepage body in the dam is adopted, the height of a pre-seepage line of tailings is effectively controlled, the seepage line is prevented from rising, the stability of the dam body is guaranteed, the maintenance cost is lowered, and a large amount of later treatment cost is saved for enterprises. Meanwhile, the drainage-seepage structure is reasonable, the technology is simple, construction is convenient, the construction period is short, the cost is low, the drainage-seepage effect is good, and therefore the potential safety hazards that the tailing dam is in danger, collapses, breaks and the like are eliminated.

Description

Technical field [0001] The present invention involves a preventive measures that prevent the rising of dams caused by the rising of dams caused by the residue of residues in the industrial mining plant or the fire power generation industry.The buried method of pipe osmosis. Background technique [0002] The tailings dam are important facilities for the infrastructure of various types of metallurgy industry and the infrastructure of thermal power plants. It is an important part of ensuring the normal production of various types of minerals and thermal power plants., The amount of tailings excreted by the minerals and the amount of ash residue discharged from the power plant also increased sharply. Many of the followers of the safety and environmental protection issues related to the tailings dam and ash dregs dams are increasingly prominent., Collapse, dams such as damping, and other malignant accidents occur.At present, the main method of embedded and discharge of the new dam bod...
