Method for removing UPVC double-wall corrugated precipitation tube well
The invention relates to tube well construction, in particular to precipitation plastic tube well construction. A method for removing a UPVC double-wall corrugated precipitation tube well comprises the steps: first four hanging bars are evenly arranged on the outer side of the UPVC double-wall corrugated precipitation tube well; the hanging bars are made of steel bars and externally wrapped with a plastic film, a cutting knife with a hook is welded to the bottom of each hanging bar, the inner side of the bottom of the hook of the cutting knife is provided with a blade, and the top of each hanging bar is provided with a hanging ring; the edge part of the cutting knife is embedded upwards into a tube well bottom cover, and a cutting edge of the cutting knife is placed at the bottommost part of the UPVC double-wall corrugated precipitation tube well; precipitation operation is performed; finally, after the precipitation operation is finished and drainage facilities in the tube well are recycled, a lifting appliance is used to pull upwards the hanging ring located on a tube well upper opening, a mode of multiple lifting or single lifting is adopted, the goal of cis-cutting is achieved, a UPVC double-wall bellows well tube divided into four pieces after the cutting is separated from a well opening and taken out manually. The method is simple and easy to operate, and environmental pollution is reduced.
