The method comprises the steps that a supporting pipe is obliquely supported into a small chamber to serve as a supporting rod, the top end of the supporting rod is connected with an anti-skid plate, the anti-skid plate abuts against the side wall of the small chamber, and a bolt hole in the upper portion of the supporting rod is connected with a lifting hoist through a jack rope; a lifting hook on the lifting hoist is lowered to the position above the pipe opening of the filling pipe; a jack rope connected with the lifting hook is connected with lugs protruding out of the two ends of a flange of an upper pipe opening of the filling pipe, and the filling pipe is slowly lifted to the maximum height capable of being lifted by an electric hoist through a lifting hoist; a flange is fastened below the exposed part of the filling pipe, and the filling pipe is cut along the upper part of the flange; and the lifting, fastening and cutting processes are repeated until all the filling pipes are pulled out of the vertical steel sleeve. In the limited underground working space, the plastic filling pipe in the steel sleeve is stably taken out and replaced, and safe and efficient operation of the filling pipe is guaranteed.
本发明公开了一种竖直钢套管内更换充填管的方法，包括：将支撑管斜撑进小硐室作为支撑杆，支撑杆顶端连接防滑板且防滑板紧靠小硐室的侧帮壁，支撑杆上部插销孔通过千斤绳连接起吊葫芦；将起吊葫芦上的吊钩下放至充填管管口上方；吊钩连接的千斤绳与充填管上管口的法兰两端突出的耳朵连接，用起吊葫芦慢慢拉升充填管至电动葫芦所能起吊的最大高度；充填管露出部分下方紧固一个法兰，沿该法兰上方切割充填管；重复起吊、紧固、切割过程，直至所有充填管被拉出竖直钢套管。本发明在地下有限的作业空间内，将钢套管内的塑料充填管稳固取出更换，保证了充填管安全高效运行。
