Damaged hardened channel underwater repair device and using method thereof

Abstract

The invention provides a damaged hardened channel underwater repair device, and relates to the technical field of water conservancy channel repairing. The technical problem of affected water transportwork due to the fact that a damaged hardened channel is repaired by generally adopting water supply cutting off operation, the damaged hardened channel underwater repair device comprises a working cabin, a drainage device, and a channel for entering the cabin, wherein the working cabin comprises a cover body, and the cover body is placed at the channel damaged position and jointly forms the working cabin with the surface of the channel; the drainage device communicates with the working cabin, the drainage device is capable of injecting high-pressure air into the working cabin and draining water from the working cabin, and thus the inner space of the working cabin is isolated from water in the channel; and the channel for entering the cabin communicates with the working cabin, and construction personnel or maintenance equipment can enter the working cabin through the channel for entering the cabin to repair the channel damaged position. According to the damaged hardened channel underwater repair device, the damaged hardened channel can be repaired underwater.

Description

technical field [0001] The invention relates to the technical field of restoration of water conservancy canals, in particular to an underwater restoration device and method for damaged hardened canals. Background technique [0002] The South-to-North Water Diversion Project diverts water from the Danjiangkou Reservoir at the junction of the Hanshui River and its largest tributary, the Danjiang River, and supplies water to most areas of the Huanghuaihai Plain. Cities solve the problem of uneven spatial distribution of water resources in my country, and provide drinking water and agricultural irrigation water for more than 20 large and medium-sized cities along the route. It is an irreplaceable and important water source in the Beijing-Tianjin-Hebei region, ensuring its long-term stability and uninterrupted The most basic requirements for the operation and maintenance of water supply projects. [0003] Since the first phase of the middle route of the South-to-North Water Divers...
