Membrane structure protective wall for dam scouring protection and application method thereof

Abstract

The invention discloses a membrane structure protective wall for dam scouring protection and an application method thereof. The protective wall has two types: A and B; a plurality of strip-shaped water-absorbing expansion bags filled with water-absorbing expansion resin are attached to the wall body of the membrane structure protective wall in the direction perpendicular to the horizontal axis ofthe wall body; after the membrane structure protective wall is placed into water, the water-absorbing expansion bags attached to the wall body of the membrane structure protective wall can absorb water to expand, so the wall body of the membrane structure protective wall is unfolded and flattened. The beneficial effects are that when a dike is scoured and damaged, the dike can be quickly separatedfrom a dike root riverbed to a dike corner, a dike body and torrent through the arrangement of the membrane structure protective wall, and scour and damage of torrent to the dike are prevented, so the purposes of stabilizing the dike foot, fixing the foundation and preventing scour are achieved, the protection is quick, and the excessive manpower and material resource input is not needed.

Description

[0001] technical background: [0002] In the flood season, it is not uncommon for the embankment foundation to become unstable due to the erosion and invasion of the embankment slope by the flood water, which in turn leads to bank collapse and other dangerous situations. Embankment scour protection and bank collapse emergency rescue have always been severe challenges for flood control and emergency rescue. [0003] In June 2017, I applied for a patent (ZL201710407106.7) entitled "A Movable Embankment Protective Floating Wall", which discloses a "protective floating wall" for embankment scour protection and bank collapse danger. The main technical characteristics of the new technology of rapid rescue are: [0004] "Protective floating wall" is a high-tech product used for embankment scour protection and rapid rescue of dangerous bank collapses. Through its layout, an isolation curtain wall can be quickly formed between the torrent and the embankment in a short time to protect th...

Problems solved by technology

[0009] After two years of application practice, it is found that there is a serious deficiency in ZL201710407106.7, that is: when the embankment is scoured and damaged by the torrent, the embankment angle and the embankment root riverbed will be scoured and damaged at the same time, as shown in the attached picture (2) As shown in the shaded part, the existing protective floating wall in ZL201710407106.7 can only effectively protect the corner part of the embankment, but cannot protect the riverbed at the root of the embankment.
