Quick Overhaul Method for Corroded Plane Gate of Hydropower Station

Abstract

The invention discloses a rapid repairing method of a corroded plane gate of a hydropower station. The rapid repairing method comprises the following steps that a temporary workshop rail is installed in agate slot hole opening of the gate to be repaired; the corroded plane gate to be repaired is hoisted to the hole opening for being locked; a curved steel tube frame movable workshop is installed; the curved steel tube frame movable workshop is hoisted to the gate hole opening for being locked, and dredging operation is carried out; cutting is conducted by using a plasma cutting machine, and after detaching a gate attachment, the curved steel tube frame movable workshop is moved to shield the gate; abrasive blasting operation is conducted for removing an old zinc layer; a gate water sealing seat plate vertically-moving machining device is used to conduct vertically-moving finish machining on a gate deformed water sealing seat plate; respraying is conducted on the gate by using semi-automatic electric arc thermal spraying zinc; accessories are installed after sealing by using inorganic spraying paint; and the gate is locked. The rapid repairing method solves repairing and restoring of all kinds of corroded plane gates of the hydropower station, and especially solves the construction problem of inconvenient transportation of plane gates of large section welding.

Description

Technical field: [0001] The present invention relates to a rapid maintenance method for various types of planar corrosion gates of any hydropower station, and particularly relates to a rapid maintenance method for hydropower station corrosion planar gates that can solve the construction problem of inconvenient transportation of super-large inter-node welded planar gates. Background technique [0002] As we all know, the gate operation of a hydropower station directly affects the optimal operation of the units of the hydropower station. The normal operation of the gate is the key to ensuring the installation and operation of the power station, and the plane gate is almost indispensable in the layout and design of various power stations, so how to quickly repair the corroded plane gate Recovery technology has also become the primary consideration in the operation of various power stations. [0003] The maintenance period of the plane gates of hydropower stations is generally about 5 ...
