发明名称 Joint sealing method
摘要 A method for installing a mold apparatus in a manhole assembly and filling the mold apparatus with a sealing material to establish a solid bond that blocks inflow of fluids at the joint between abutting components of the manhole assembly includes providing an open ring, a retaining band for urging the open ring into contact with the manhole so that the open ring defines an annular channel at the joint, and a sealing material dispenser for conveying sealing material into the annular channel. The sealing material hardens in the annular channel to provide the solid bond at the joint between the two manhole components. The manhole components may be an abutting manhole frame and manhole, or two abutting sections of manhole.
