| description | The utility model discloses an outer bell and spigot steel die for pipeline repair, which belongs to the field of X. The outer bell and spigot steel die comprises a plurality of steel pipes, one end of each steel pipe is provided with an insertion pipe, the other end of each steel pipe is provided with an insertion hole, the outer edge diameter of each insertion pipe is smaller than that of each steel pipe, and the inner edge diameter of each insertion pipe is equal to that of each steel pipe. The outer side of the insertion pipe is sleeved with a waterproof rubber ring, and the outer side wall of the waterproof rubber ring abuts against the inner side wall of the insertion hole. During installation, the outer side of the insertion pipe is sleeved with the waterproof rubber ring, the inner side of the waterproof rubber ring is inserted into the installation ring groove, installation of the waterproof rubber ring and the insertion pipe can be completed, then the insertion pipe is inserted into the insertion ho |
