A Little Wisdom Helps You Become Smarter !In the video, Villagers are manually clearing silt and small rocks from under a narrow stone bridge arch. With heavy machinery unable to reach this confined space, people dig out debris using hand tools like picks and shovels.
Why it matters : Blocked arches weaken bridges during floods and disrupt water flow. While this method works, it's slow and labor-intensive.
Better solution : Use a portable gas-powered water pump (trash pump). Position it upstream to push water through a hose directed at the blockage. The high-pressure stream breaks apart silt and washes rocks into open sections of the dry riverbed. Post-flush, workers easily remove leftover stones by hand. It’s safer, 10x faster, and costs less than 2 days’ manual labor.
