Definitions

  • the present invention relates to a method of sealing a manhole riser and a catch basin, as well as sealing storm sewer pipes. More particularly, it relates to an improved, economical method to seal a manhole riser and catch basin from unwanted water and other contaminants which leak therethrough.
  • Manhole risers, manhole chimneys all generically describe the top of the unit which extends from sewer pipes to the ground surface.
  • the top portion of the manhole riser comprises numerous cement adjusting rings, which sit atop each other and typically have specific dimensions. Each ring may be added to increase the height that the manhole riser extends to. As a road is repaved and new layers of pavement are added, it often times is necessary to add an additional ring such that the manhole covers stay flush with the road.
  • Catch basins are situated below storm sewer drainage grates found on roads.
  • the storm sewer grates are collection sites for water drainage from streets which flow through catch basins.
  • Catch basins generally comprise a series of rectangular cement rails or collars.
  • the cement collars are stacked in a manner to create a rectangular "basin" through which water passes.
  • Each collar of the basin generally comprises two three-sided cement rails which, when fitted together, create a rectangle.
  • the catch basins extend up to the grate, through which drainage water passes.
  • a problem that has existed with manhole risers and catch basins in the past is surface water passes through gaps and spaces in the cement rings and cement collars. Further, the water will often times freeze between and within the cement structures, and the freeze/thaw cycle will deteriorate and break up the cement structures, requiring them to be replaced.
  • Adjustment/adjusting is a process whereby the manhole riser or storm catch basin is adjusted to the height of the road surface.
  • a manhole for access to the infrastructure system is constructed according to engineering plans on a straight line. If the road has a curve, it requires more manholes than a straight road.
  • the bottom section of the manhole utility access is called a barrel, and between the barrel and riser is the "cone".
  • the cone is made of pre-cast concrete and will not leak because it is one piece. After the cone is placed in position, the adjustment process begins at the top of the cone in order to cause the manhole riser necking 'to meet flush with the road surface.
  • By using concrete adjusting rings and mixed Portland cement on top of the cone rings are stacked to bring the manhole and top casting to the road elevation. The procedure is similar for storm catch basins.
  • filter blanket is a geo-textile fabric material that is placed on new roads that have poor underlying soils.
  • the filter blanket gives strength to the road surface.
  • a contractor will simply cut off a piece of the filter blanket and wrap around the manhole neck to help prevent sand and dirt from passing into the manhole.
  • the filter blanket is not adequate for the prevention of water to pass into the adjustment rings.
  • the present invention eliminates contaminated water, sand, dirt and other debris from penetrating into water system infrastructures, and thereby eliminates or reduces the amount of water treatment needed at the city water treatment plant. It is the object of this invention to provide an economical method of sealing the intersection between two adjoining pipes.
  • the present invention also reduces the amount of ground erosion associated with cracks and leakage caused by cracks in manhole risers and catch basins.
  • the present invention describes and claims an improved method for sealing a manhole riser or catch basin.
  • the invention also describes and claims an improved kit for sealing manhole risers and catch basins.
  • the method of sealing a manhole riser, with adjusting rings is described as follows : a. selecting a first and second band of elastomeric material, said first and second band having a total height of at least the height of the manhole riser from the base of the bottom adjusting ring of the manhole riser to the top edge of the top adjusting ring of the manhole riser; b. placing the first band over the manhole adjustment area and positioning the bottom edge below the adjustment on the cone; and c. placing the second band over the manhole riser, positioning the second band such that it extends over the top edge of the first band and also extends over the top edge of the top adjusting ring.
  • the present invention also discloses a kit for sealing manhole risers.
  • the kit comprises: a first and second band of elastomeric material, the first and second band having a total height of at least the height of the manhole riser from one inch below the base of the bottom adjusting manhole riser to the top edge of the top adjusting ring of the manhole riser.
  • the present invention also addresses sealing catch basins.
  • the method for sealing catch basins comprises the following steps: a. selecting a first and second band of elastomeric material, the first and second band having a total height of at least the height of the catch basin from the base of the bottom adjusting catch basin ring to the top edge of the top adjusting ring of the catch basin; b.
  • first band over the catch basin and positioning a bottom edge of the band at the base of the catch basin, a top edge of the first band extending toward the top of the top adjusting collar; and c. if necessary, placing the second band over the catch basin, positioning the second band such that it extends over the top edge of the first band and also extends over the top adjusting ring and into the edge of the catch basin casting.
  • the present invention also describes a kit for sealing catch basins.
  • the kit comprises: a first and second band of elastomeric material, the first and second band having a total height of at least the height from one inch below the bottom of the catch basin from the base of the bottom adjusting catch basin ring to the top edge of the top adjusting ring of the catch basin.
  • a method to seal pipe intersections and barrel intersections which are sealed together underground to support a cone comprise a tape having two strips of adhesive applied to one side of the tape. The tape is dispensed, a release liner is peeled off of the adhesive, and the tape is tightly wrapped around the riser, cone or other conduit which needs to be sealed. The ends are overlapped and sealed with a block of mastic.
