[0001] This application claims the benefit of U.S. Provisional
Application No. 61/005,582 filed Dec. 6, 2007.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention comprises an apparatus and a method
for raising the elevation of a catch basin during reconstruction or
repaving of roadways. In particular, the apparatus of the present
invention provides a catch basin riser that elevates the entire
profile of the catch basin. More particularly, the novel apparatus
provides for a method of installation that saves a great deal of

[0004] 2. Brief Description of the Related Art
[0005] An improved grate riser assembly is disclosed in U.S. Pat.
No. 5,320,445 to Farrelly. The disclosed device is for use with
catch basins and the like comprising vertically open rectangular
frames with two opposing frame sections. The device further
comprises inwardly projecting horizontally grate support flanges.
The cooperating grates have opposite end portions of parallel
spaced-apart grate members resting on the support flanges. The
grate riser assembly includes two or more grate risers having
vertically open, generally rectangular frames coextensive with the
catch basin frame. The grate risers define opposing vertical side
and end wall sections of a height substantially equal to the depth
of pavement overlay. The new grate riser frame rests atop the
original catch basin frame with its top edge substantially level
with the top surface of the pavement overlay. Essentially, the
patent to Farrelly discloses positioning one grate frame on top of
another.
[0006] U.S. Pat. No. 5,956,905 to Wiedrich discloses a molded
plastic extension member for increasing the height of manholes or
catch basins when resurfacing a roadway. The extension member also
defines angles of slope in order to adjust the angle of the catch
basin support frame or the manhole cover support frame. Several
sloped extension members may be stacked to create a desired angle
of slope relative to the new road surface. In addition, the
extension member includes a pocket adaptable for receiving and
retaining mortar between two stacked extensions. As with the patent
to Farrelly, the patent to Wiedrich discloses positioning one
support frame on top of another.
[0007] US Patent Application Publication No. 2002/192023A to
McNeely discloses an assembly for adjusting the elevation of a
structure such as a manhole or a catch basin to be surrounded by
pavement. A one-piece adapter is formed to be inserted between an
existing base rim and the cover of the structure. A lower member of
the adapter is received in the original base rim to be supported on
an internal shoulder. An upper member of the adapter extends
outwardly from the lower member of the adapter to receive the
original cover while engaging the upper end of the original base
rim and forming an upward extension of the rim. Additional adapters
may be inserted to further increase the elevation of the structure
with all the adapters being nestled within one another. In sum, the
disclosed device provides simple adapters to be placed within a
catch basin assembly or a manhole assembly, and then the entire
original catch basin assembly or manhole assembly is covered with
layers of asphalt. With respect to catch basins, this disclosure is
similar to the patents to Farrelly and to Wiedrich in that the
device disclosed by McNeely also teaches positioning one support
frame on top of another.
[0008] Accordingly, it is an object of the present invention to
overcome the shortcomings of the prior art stated above and provide
an economical and robust catch basin riser and an efficient method
for raising the elevation of the catch basin. It is another object
of the present invention to provide a method of installation which
would save a great deal of time, labor and expense during
reconstruction or repaving projects.
DESCRIPTION OF THE INVENTION
[0009] The present invention comprises an apparatus and a method
and for raising the elevation of a catch basin. In particular, the
catch basin riser comprises a grill spacer and a new and reinforced
catch basin top to be bonded to the existing catch basin top. The
present invention alleviates the problem of having to remove the
original underlying catch basin top during reconstruction or
repaving of a roadway. Accordingly, the present invention provides
a method of installation that saves a great deal of time, labor and
expense during reconstruction or repaving projects.
[0010] The method for raising the elevation of a catch basin
according to the present invention raises the existing catch basin
grill elevation to match the desired level of the "new" roadway.
The method of the present invention can be employed during a
variety of road construction projects including, but not limited
to, road surface reclamation, road resurfacing, road repair, and
the like, and all such road construction projects will be referred
to herein as producing a "new" roadway. The elevation of the catch
basin riser of the present invention is set to a desired elevation,
with respect to the elevation of the new roadway, by construction
and insertion of a spacer which is inserted into the existing catch
basin. Preferably, the spacer is fabricated from galvanized iron,
and also may be fabricated from any other suitable material.
[0011] The new catch basin top comprises reinforced concrete of any
desired thickness and such catch basin tops are made available for
each particular reconstruction or repaving application. Preferably,
the unit is fabricated from reinforced self-compacting concrete
settling at the desired thickness for the roadway project. Each
unit is bonded to the existing catch basin top to allow repaving
without the need to remove or replace the existing catch basin top.
The method selected for bonding one concrete surface to another may
be any one of a number of known conventional techniques. One
preferred method comprises the use of an epoxy-concrete bonding
mix.
[0012] The catch basin top according to the present invention
contains several angle iron and rebar reinforcements in order to
provide stability for transport, installation and use. As described
in more detail with reference to the figures, a preferred catch
basin top comprises galvanized angle iron reinforcement and a
galvanized flat steel bar at its front face, the curbside face. The
catch basin top further comprises galvanized angle iron
reinforcement around the open face of the top juxtaposed to the
grill spacer. Although it is preferred that the catch basin riser
of the present invention comprise angle and rebar reinforcements,
other methods of reinforcement are considered within the scope of
this invention.
[0013] The present invention also discloses a method of installing
the catch basin riser. The installation of the catch basin riser is
accomplished by removing the existing catch basin grill in the
field and exposing the ledge, flange, angle iron protrusion, or the
like in the existing catch basin top upon which the grill was
previously seated (hereinafter referred to as the "ledge"). The
prefabricated spacer is positioned within the existing catch basin
upon the exposed ledge. The new catch basin top is bonded onto the
existing catch basin top and the original grill is positioned upon
the spacer and proximate to the inner surfaces of the new catch
basin top and the existing catch basin top. Moreover, if the catch
basin grills in a particular area of a road construction project
are at risk for being pulled up or out-of-place by hot truck tires,
then the grill spacers can be tack-welded onto the existing catch
basin top angle iron ledge, and the grill can be tack-welded onto
the grill spacer to prevent any lifting problem. The catch basin is
then ready for repaving.
