Deep vertical shaft self-adaptive protection device based on constant-resistance large-deformation structure

Abstract

The invention relates to a deep vertical shaft self-adaptive protection device based on a constant-resistance large-deformation structure. The device is arranged between two of multiple sections of shaft walls which are arranged in a deep vertical shaft from top to bottom. The device comprises an upper module, a lower module, a sealing module and a constant resistance body. The upper module comprises a circular ring-shaped top plate, a hollow annular outer sealing barrel and a constant-resistance large-deformation rod body, the lower module comprises a circular ring-shaped base, a hollow annular inner sealing barrel and a constant-resistance large-deformation sleeve, the inner sealing barrel is inserted in the outer sealing barrel, the sealing module comprises a steel wire brush arranged in the inserted gap between the outer sealing barrel and the inner sealing barrel and grease with which the steel wire brush is filled, the constant resistance body is installed on the lower surface ofthe constant-resistance large-deformation rod body, the lower surface of the constant resistance body makes pressing contact with the constant-resistance large-deformation sleeve, the lower surface of the constant resistance body is pressed into the deformation sleeve when pressed by the upper portion, and therefore opening deformation of the deformation sleeve is achieved. Compared with the prior art, the deep vertical shaft self-adaptive protection device has the advantages that protection is effective, sealing performance is good, deep vertical shaft structure safety is ensured, installation is flexible, and monitoring and early warning are achieved.

Description

Technical field [0001] The invention relates to the field of protection engineering of vertical shaft structures, in particular to a deep vertical shaft self-adaptive protection device based on a constant resistance and large deformation structure. Background technique [0002] The non-mining damage of the shaft shaft during the mining process is a special mine geological disaster. It is mainly manifested in that the shaft wall of the shaft shaft is seriously deformed and severely deformed when the shaft shaft of the coal mine has sufficient security pillars. Rupture makes it difficult to lift and transport. Some wellbores are accompanied by a large amount of water influx and sand, and the non-mining failure of vertical shafts has a certain periodicity, that is, many vertical shafts undergoing repeated deformation after normal use for a period of time Therefore, the engineering geological disasters caused by non-mining damage of the shaft shaft seriously affect the normal operati...
