A kind of duckweed type embankment loophole sealing method

Abstract

The invention relates to a duckweed type dyke-dam leak stoppage method and belongs to the technical field of emergency treatment of dykes and dams in water conservancy projects. The IPC class number of the duckweed type dyke-dam leak stoppage method is E02B 1 / 00, E02B 3 / 02. A stoppage device adopted in the duckweed type dyke-dam leak stoppage method is composed of seven portions of a leak water inlet position indicator, a duckweed-shaped floating object, a conical connecting rope, high-water-absorbing-quality resin balls, a series connection rope, a counter weight and a traction rope. When the stoppage device moves to a leak water inlet, the water pressure and the suction force of water flow enable the counter weight and the high-water-absorbing-quality resin balls connected through the series connection rope to be sucked into the leak. Water-soluble bags are dissolved through dipping in the water flow in the leak, high-water-absorbing-quality resin rapidly expands after absorbing water and is tightly combined with the wall of the leak, and a series connection type closed space is formed in the leak; and in this way, the effects of step-by-step stoppage and step-by-step sealing in the leak are achieved, and the seepage line of a dyke-dam body cannot greatly rise.

Description

Technical field: [0001] The invention relates to a duckweed-type embankment leakage sealing method, which belongs to the technical field of embankment and dam emergency rescue in water conservancy projects, and its IPC international patent classification numbers are E02B 1 / 00 ​​and E02B 3 / 02. Background technique: [0002] Leakage is a water flow channel that runs through the embankment (dam) body or embankment (dam) foundation, and is a relatively common danger in embankments. When the water depth of the leaky water inlet exceeds 1.5m, due to the difficulty of early detection and sealing, it is easy to cause the dam to burst and bring disaster losses. [0003] The principle of leak emergency rescue is "blocking the front and leading the way later, and simultaneously developing the back". The existing technology usually divides the "blocking the front" into three steps. First detect the water inlet of the leak, then use plugging or capping to seal it, and finally use clay t...

AI Technical Summary

Problems solved by technology

However, the above-mentioned device has problems such as the inability to indicate the location of the piping, the long-term preservation of the leak-stopping bag, the inability to control the underwater expansion time of the leak-stopping bag, making it difficult to enter the leak, and the position of the leak-stopping bag in the hole is difficult to fix.
