Eco-friendly Method of Removing Underwater Structure by using of Improved Worktable for Removing Underwater Structure and Air-lift pump

摘要

An object of the present invention is to provide a piercing workbench for demolishing an underwater structure and an air lift pump using the piercing workbench and an air lift pump for removing pierced pore water using an air lift pump, It is possible to discharge the purified water and improve the safety and workability by reducing the underwater work during the demolition of underwater structures by using the improved drilling workbench to maintain the perforation interval. It minimizes the noise and vibration generated during the work, Provides a method of removing eco-friendly underwater structures by using a piercing workbench for demolishing underwater structures and an air lift pump that can effectively break down and salvage underwater structures while preventing pollution of rivers or oceans by collecting and purifying the entire polluted water.In order to achieve the above object, according to the present invention, there is provided a barbed wire having a steel frame structure protruding outward from one side of a barge, a wire net is placed on the foot plate, A safety guardrail 12 is installed and a plurality of guide pipes 13 are installed on the footrest 11 at constant intervals and are extended in a predetermined length in a downward direction. 13 and a piercing and dirt collecting tank 14 is installed in a tubular shape which is opened only at an upper part of the piercing and collecting tank 14 and a transfer pipe 20 connected to the pump 15 is connected to the piercing dirt collecting tank 14, The present invention relates to an improved underwater structure demolition workbench having a plurality of sedimentation tanks 17 for transferring polluted water and purifying the polluted water, and a method for removing eco-friendly underwater structures using an air lift pump.
