ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a system and method for installing a catch basin, and more particularly, a system and method for facilitating the removal of a portion of the basin such that the top edge of a basin or vertical extension and grate lie in a plane which is substantially co-planar with a surface of the ground.
2. Description of the Related Art
Modern sewage and drain systems oftentimes include catch basins for directing fluid, such as rain water, sewage and the like. The basins typically comprise a sewer cover and a vertical connector line which provides access to subterranean lines which are typically networked beneath ground level. A manhole is essentially a vertical passageway, typically beginning at ground level or at or near the street surface and extending downward into the ground into communication with the subterranean lines. The lines may be discharged directly into rivers or streams, or for sewage, to a sewage treatment facility so that waste and drainage may be properly processed.
Typically, manholes are formed through various construction techniques of bricks, tiles or concrete blocks bound together with cement mortar. Pre-cast and cast-in-place concrete manholes are also common.
The prior art reflects various types of devices for adjusting the position of the manholes or drain cover such that it is situated at substantially ground level. Without such devices, the manhole or drain cover may extend an undesirable length above the ground or too far below the ground, making access difficult and/or inhibiting or interfering with the operation of the drain or sewage system.
For example, U.S. Pat. No. 5,505,814 to Marshall discloses a roof drain receptacle for attachment to an upper surface of a roof deck for supporting the drain body at adjustable variable heights above the roof deck. Likewise, U.S. Pat. No. 4,197,031 discloses a vertically adjustable manhole cover. These references, as well as other known prior art, have numerous drawbacks, such as requiring multiple component parts and numerous steps and adjustments needed for proper assembly.
What is needed, therefore, is a simple system and method for situating a catch basin or line in the ground wherein the vertical component of the line or basin can be quickly adjusted so that its end is at ground level.
SUMMARY OF THE INVENTION
It is, therefore, an object of the invention to provide a system and method for installing a catch basin or similar drain line such that the end of the basin is at a predetermined or desired level, such as ground level.
Another object of the invention is to provide a system and method that reduces the need for numerous assemblies and components.
Still another object of the invention is to provide a system and method which, when used or followed repeatedly, requires a relatively small amount of skill and utilizes only a few installation steps.
In one aspect, a catch basin installation system comprises a basin defining a conduit through which fluid may pass, an adjustable collar for positioning around the basin, the adjustable collar providing a guide for removing an above-ground portion of the basin so that an opening of the basin is substantially co-planar with the ground, and a grate for situating in the opening.
In another aspect a catch basin installation system comprises a basin defining a conduit through which fluid may pass, a guide on the basin for identifying an above-ground portion of the basin and a below-ground portion of the basin, the guide facilitating removal of the above-ground portion of the basin, and a grate for situating on the edge.
In still another aspect, a method for installing a catch basin comprises the steps of placing the catch basin in the ground, situating a collar around a portion of the catch basin at substantially ground level, and using the collar as a guide to removing an above-ground portion of the catch basin so that a top edge of the catch basin is substantially co-planar with ground level.
In yet another aspect a catch basin installation method comprising the steps of providing a basin defining a conduit through which fluid may pass, providing a guide on the basin for identifying an above-ground portion of the basin and a below-ground portion of the basin so that the above-ground portion of the basin may be easily identified and removed, and providing a grate for situating on the edge.
In a further aspect an adjustable guide for situating on a portion of a line, comprises a guide having an opening which generally complements the shape of the catch basin and at least one fastener for adjustably securing the guide to the catch basin, the guide providing a guide surface for guiding a cutting tool to cut the basin, thereby leaving a top edge of the basin substantially co-planar with the ground surface.
These and other objects and advantages of the invention will be apparent from the following description, the accompanying drawings and the appended claims.
