Abstract

The invention discloses a stilling pool slope angle underwater repairing device and method. The stilling pool slope angle underwater repairing device comprises a device body, the device body is composed of a fan-shaped cylindrical tube and a cylindrical tower tube communicating with the upper side of the tube, the side wall between angular radii in the length direction of the tube is open, a sealing strip is arranged on the boundary of the tube, and a communicating valve is arranged at the connecting ends of the tower tube and the tube. According to the underwater repairing device and method,underwater construction repairing can be conducted, the construction process is simplified, and the repairing efficiency of the stilling pool slope angle is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to an underwater repair device and repair method for slope angles of stilling pools. Background technique [0002] In recent decades, my country's water conservancy projects have achieved remarkable achievements and developments. In particular, the design and construction technology of high dams is at the leading level in the world, and a number of high dams and large reservoirs have been built one after another. With the completion and commissioning of these hydropower projects, my country's hydropower industry has also entered a new stage of development. A good operation and maintenance mechanism is the main issue that needs to be paid attention to in the future development of the hydropower industry. According to the data of the first national water conservancy census, there are about 60,200 dangerous reservoirs in my country's built reservoirs and dams. Th...
