Abstract

The invention discloses equipment, in particular a relief well washing and grappling combined system for water engineering, which comprises four parts, namely air supply equipment, hoisting equipment, grappling equipment and water outlet equipment. The air supply equipment consists of a tyre type air compressor, a flexible duct and a hard duct; the hoisting equipment consists of a triangular support, a hoisting cable, a fixed windlass and a diesel engine; the grappling equipment is a three-tooth jet-grab-cone; and the water outlet equipment is a seamless steel pipe. The relief well washing and grappling combined system has the advantages of simple, reasonable and applicable structure, convenient operation, novel design, adaption to different geographical conditions and good washing and grappling effect, and is simple and practical.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a combination system for washing and fishing of a water engineering decompression well. Background technique [0002] The safety and stability of water conservancy projects, especially reservoir dams, depend to a large extent on the confined water level of the dam foundation. If the confined water level of the dam foundation is too high, it will be very unfavorable to the safety and stability of the dam, and it will also cause swamps on the land behind the dam. In order to reduce the pressure-bearing water level of the dam foundation, improve the anti-sliding stability of the dam body, and reduce the groundwater level of the land behind the dam, it is necessary to build a seepage and pressure reduction project, and the relief well is one of the components. Generally, the depth of the relief well is about 30 meters. However, during the operation for many years, the relief well will be clogg...
