AI Technical Summary
After the traditional infiltration well is formed, a lead wire is wrapped in nylon cloth or wire mesh at the bottom of the filter tube. Due to the quality and material specifications of the holes, it is often impossible to effectively prevent sand from returning to the bottom of the holes and silt inside the holes.
A bottom sealing device for the drainage well of tailings ponds was designed, including permeable test blocks in stainless steel mesh cages. The permeable test blocks are composed of granite particles and polymer fiber porous concrete. They are slowly lowered to the bottom of the well by a winch to prevent sand from returning to the bottom of the hole and reduce the dam body infiltration line.
It effectively ensures a certain amount of water influx, prevents sand from returning to the bottom of the hole, reduces the dam body infiltration line, ensures stability of the dam body, and simplifies operation through automatic decoupling device and improves convenience.
