  • Appl. No.:
    9/173148

  • International Classification:

  • US Classification:
    404 26
  • Abstract:
    Embodiments of apparatus and a method of raising a manhole ring during construction or repair of roads are shown and described. The apparatus and method include formation of a manhole collar by use of a form that rests on a manhole cone and trimming the form to have its top edge at the correct elevation and orientation to properly receive the manhole ring. After the manhole ring is received on the form, a single monolithic pour of concrete creates a concrete collar that fills and seals the vertical space between the manhole cone and ring and the manhole ring is thus secured and sealed at the proper elevation that results in the manhole ring and its cover being level with the surrounding pavement. The apparatus includes an accurate custom-trimming assembly indexed off of the pavement surface for trimming the form to the proper dimensions for the particular site.
