Technical Field
The invention relates to the technical field of earthwork construction methods, in particular to the technical field of dam breach plugging construction methods.
Background
The existing method for blocking the breach of the levee uses sand and stone materials, and a large amount of sand and stone materials are needed for each breach. The sand and stone materials transported to the breach are pushed into the water and mostly washed away by the flood, i.e. the filling is carried out by using the reinforcing mesh for a plurality of times. At present, there are three main types in dike breach plugging technology: vertical plugging method, horizontal plugging method and mixed plugging method.
1) The vertical blocking method is to make the water enter from one or two ends of the breach door according to the planned blocking dyke line, and gradually narrow the breach door, and finally realize closure.
2) The block method is to fill the river bottom with stuffing material, such as willow stone pillow, stone, sand bag, etc. along the width of the gate layer by layer until the stuffing material is higher than the water surface to block the water flow.
3) The mixed plugging method is characterized in that a vertical plugging method and a horizontal plugging method are comprehensively applied according to local conditions according to the specific conditions of a port door during plugging.
However, the technical methods all consume a long time, when the large river makes a breach at a high water level in a flood season, the breach flow rate is large, the wrapping head is seriously flushed, the breach is rapidly enlarged, the filler of the conventional plugging technology cannot be fixed, the breach cannot be plugged in time, and the method often causes serious threats to lives and properties of people.
