A kind of embankment loophole sealing device

Abstract

The invention relates to a dyke-dam leak stoppage device and belongs to the technical field of emergency treatment of dykes and dams in water conservancy projects. The IPC class number of the dyke-dam leak stoppage device is E02B 1 / 00, E02B 3 / 02. The dyke-dam leak stoppage device 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 dyke-dam leak stoppage device is moved 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 belongs to the technical field of emergency rescue of embankments and dams in water conservancy projects, and in particular relates to a leakage plugging device for embankments, whose IPC international patent classification numbers are E02B 1 / 00 ​​and E02B 3 / 02. Background technique: [0002] A leak is a water flow channel that runs through the dyke (dam) body or the dyke (dam) foundation, and is a common danger for dams. When the water depth of the leaky inlet exceeds 1.5m, it is difficult to detect and block it early, which will easily cause the dam to burst and bring disaster losses. [0003] The principle of loophole rescue is "blocking the front and leading the back, and doing the same while facing the back". The existing technology usually divides the "blocking front" into three steps. First, the leaky water inlet is detected, then plugged or capped, and finally closed with clay. Detection, sealing, and air closure are carried ou...

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.
