Background

Under the condition of flood season or high water level, transverse dam or foundation seepage holes appear near a dam backwater slope or slope toe, and are called leaks. If the leak leaks muddy water, or the clear water becomes muddy, the leak is rapidly enlarged, and the dam body is possibly collapsed or even broken. Therefore, the users must take care to find the dangerous situation of the leak and pay full attention to the discovery and the rapid rescue.

The traditional leakage plugging mode of the dam is that a large amount of bricks and stones, sandbags and the like are thrown in a leakage area of the dam, the efficiency is low, and the phenomena that the leaks continue to develop and expand due to the fact that the bricks and the sandbags are overhead can occur when the bricks and the sandbags are thrown.

Furthermore, cover films among the positive pressure soil bags, the transverse soil bag barrel and the longitudinal soil bag barrel are provided with compaction soil bags which are arranged at intervals.

Advantageous effects

Compared with the prior art, the utility model, the advantage that has does:

the utility model discloses a cover the membrane and cover the seepage zone territory, reuse clay layer will cover the membrane and compress tightly the seepage entrance to a cave after surrounding the seepage entrance to a cave through malleation soil bag, compares with the stifled mode of traditional stopper, and the sand bag use amount that can significantly reduce improves efficiency.

Fig. 1 is a schematic structural diagram of the present invention.

Wherein: 1-covering film, 2-dam, 3-fixing column, 4-rib rope, 5-transverse soil bag barrel, 6-longitudinal soil bag barrel, 7-leakage hole and 8-positive pressure soil bag.

Detailed Description

The invention will be further described with reference to specific embodiments shown in the drawings.

Referring to fig. 1, an emergency disposal structure for dam leakage includes a cover film 1 for covering a leakage area, and a plurality of fixing posts 3 inserted into the top of a dam 2. A plurality of fixed column 3 interval arrangements are on dykes and dams 2, and a plurality of fixed column 3 are arranged and are parallel with the upper end that covers membrane 1, and each fixed column 3 is connected the upper end that covers membrane 1 through muscle rope 4 respectively for taut cover membrane 1 prevents to cover the bottom that membrane 1 landing to dykes and dams 2. The upper end and the lower end of the covering film 1 are respectively provided with a transverse soil bag cylinder 5, the left side and the right side of the covering film 1 are respectively provided with a longitudinal soil bag cylinder 6, and soil is filled in the transverse soil bag cylinder 5 and the longitudinal soil bag cylinder 6 and is used for pressing the periphery of the covering film 1 on the dam 2. A plurality of positive pressure soil bags 8 are pressed on the covering film 1 on the periphery of the leakage hole 7 of the leakage area, soil is filled in the positive pressure soil bags 8, the periphery of the leakage hole 7 can be effectively compressed, the covering film 1 is used for plugging the leakage hole 7, and the leakage hole 7 is completely cut off. Be equipped with in the region that a plurality of malleation soil bags 8 enclose and compress tightly the clay layer that seepage entrance to a cave 7 with covering film 1, the clay layer can further compress tightly seepage entrance to a cave 7 with covering film 1, guarantees to fill up stifled leakproofness, simultaneously, after the cover film 1 corrosion damage of seepage entrance to a cave 7 department, the clay layer can also play the effect of filling up stifled seepage entrance to a cave 7.
