Intelligent method and system for quickly blocking gap of dam

Abstract

According to the rapid blocking method and system for the dam notch, the notch structure and water flow parameters are monitored on site, the evolution trend of the notch is calculated in combination with dam material mechanics and geometric parameters, and the size and the assembly position of a blocking body are determined according to the time condition. According to the plugging body, a hexahedral hollow box cage is modularly assembled at the position, with the small flow speed, of the upstream of a notch, and then vector propulsion is combined with water flow dragging force to be close to the notch from the upstream; the upstream end of the plugging body is located above the water surface, and the downstream end of the plugging body sinks to the upstream side of the underwater notch. According to the position and posture data collected in real time, the plugging body is tightly attached to the wall face of the dam on the upstream of the notch under the combined action of water flow and self driving through edge calculation or wired fine control of the valve and the driving device, then a ventilation or water inlet valve of the underwater box cage is closed, and sand and stone are thrown and filled on the downstream of the plugging body for stabilization.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a rapid sealing method and a sealing system for gaps in dykes and dams. Background technique [0002] Dams generally refer to buildings and structures that block water and water, usually made of earth, stone or concrete. The embankment is under high water pressure. When heavy rain or flood occurs, the water level and flow rate will increase suddenly, thus creating embankment gap. When there is a gap in the dam, if it cannot be blocked in time, the flood will submerge downstream industrial and agricultural production and transportation facilities, and even endanger people's lives and cause heavy losses. With the development of economy and society, the increase of equipment facilities and population density, the consequences of dike gap are more serious. At present, when the embankment breaks or breaches, sandbags or earth bags are used to contai...
