Drainage well drainage hole plugging structure

Abstract

The invention provides a draining well draining hole sealing and blocking structure, and relates to the technical field of a tailing pond. The draining well draining hole sealing and blocking structure provided by the invention comprises a variable-diameter pipe body, a blocking plate assembly and a sealing and blocking element, wherein the variable-diameter pipe body is used for penetrating through a draining hole of a draining well, and has a variable-diameter section with the gradually reduced outer diameter; the variable-diameter part is at least partially used for penetrating into the draining hole; the blocking plate assembly is arranged outside the variable-diameter pipe body in a sleeving way; the blocking plate assembly, the variable-diameter pipe body and the draining well form agrouting space; the blocking plate assembly is provided with a grouting hole; and the sealing and blocking element and the variable-diameter pipe body are connected for sealing and blocking the variable-diameter pipe body. The draining well draining hole sealing and blocking structure provided by the invention has the advantages that the operation is convenient; the structure is simple; the adaption to draining holes under different conditions can be met; the influence by draining hole shape, concrete falling conditions and the like is avoided, so that the sealing and blocking operation is convenient; the implementation is easy; and the sealing and blocking effects can be effectively ensured.

Description

technical field [0001] The invention relates to the technical field of tailings ponds, in particular to a drainage well drainage hole sealing structure. Background technique [0002] Drainage well is an important structure for flood discharge and return of tailings ponds. It has the advantages of good structural integrity and easy operation and maintenance, and is widely used in tailings ponds. [0003] The commonly used structural types of window drainage wells are reinforced concrete drainage wells and steel tower drainage wells. Among them, reinforced concrete drainage wells have round or square windows at different elevations on the well wall, which are generally made of wooden plugs, steel plates, concrete or other materials. However, for many tailings ponds with long operating hours, due to construction reasons or long service life, the drainage holes of reinforced concrete drainage wells have irregular shapes, and the concrete around the orifices has fallen off, resul...

[0003] The commonly used structural types of window drainage wells are reinforced concrete drainage wells and steel tower drainage wells. Among them, reinforced concrete drainage wells have round or square windows at different elevations on the well wall, which are generally made of wooden plugs, steel plates, concrete or other materials. However, for many tailings ponds with long operating hours, due to construction reasons or long service life, the drainage holes of reinforced concrete drainage wells have irregular shapes, and the concrete around the orifices has fallen off, resulting in plugs that cannot be installed or blocked. Strict; the well body of the steel tower drainage well is all welded by steel pipes, the drainage hole is a steel pipe welded on the side wall of the shaft, and the pipe opening is sealed with a steel plate or a blind flange, which is easy to operate, but the diameter of the steel tower drainage well is relatively small Small, thinner wall thickness, lighter weight, less anti-overturning ability, poor anti-deformation ability, generally can only be used in small flat storage
