Method for removing steel pipe downcomer well
The invention relates to pipe well construction. The invention provides a method for removing steel pipe downcomer wells. The method comprises: uniformly arranging and welding four hanging bars on the outer wall of a pipe well when placing a downcomer steel pipe well, the hanging bars being discontinuously welded with a downcomer well pipe, welding hanging rings on the hanging bars at interval; using nylon gauze to pack the outer wall of a filter section when placing the steel pipe well, and packing outer walls of steel pipe sections and the hanging bars by plastic films, to isolate the well pipe from contact soil; after use of thedowncomer well completes, arranging a frame-shaped base on a pipe well mouth, the base being provided with four symmetric jacks, jacking positions of the jacks being provided with an undercarriage, the positions of the undercarriage, corresponding to the hanging rings on the top of the pipe well, being provided with lifting ropes, the lifting ropes being connected with the hanging rings on the top of the pipe well; then starting the jacks, and gradually pulling the pipe well out; after stroke of the jack is in place, resetting the jacks, and connecting the lifting ropes with hanging rings on next position, so as to repeat to remove pipe wells. The method reduce potential safety hazard and pollution on environment.
