发明名称	BULKING WORK FOR MANHOLE PORT OF CLARIFICATION TANK OR THE LIKE
摘要	PURPOSE:To perform bulking work in a short time by a method in which a cylinder is formed on site and fitted on the port of a manhole. CONSTITUTION:A soft and strong flat plate 1 is cut into a length larger than the circumferential length of the port 2 of a manhole and bent to form a cylinder 7. A belt 5 is wound around the cylinder 7, the diameter 8 of the cylinder 7 is finely adjusted to fit the cylinder 7 on the port 2 of manhole, and the joint of the cylinder 7 is fixed. The belt 5 is removed out, the cylinder 7 is fitted on the port 2, and they are recovered with concrete 11. The bulking work for every manhole port 2 can thus be made possible and can be finished effectively at low cost in a short time.
