Abstract

In one or more illustrative arrangements, a utility pit system is presented that includes an inlet system that may be formed primarily of high-density polyethylene (HDPE). In one or more illustrative arrangements, the system includes a main pit that may be formed primarily of HDPE. In one or more illustrative arrangements, the system includes an outlet system that may be formed primarily of HDPE. In one or more illustrative arrangements, the inlet system is configured to operably connect to the main pit by any means of HDPE connection and thereby may form a hermetic or nearly hermetic seal. In one or more illustrative arrangements, the outlet system is configured to operably connect to the main pit by any means of HDPE connection and thereby may form a hermetic or nearly hermetic seal. In one or more illustrative arrangements, the system is configured to retain a liquid material therein.

Dependent claims

A utility pit system comprising:

an inlet system;
wherein the inlet system is formed primarily of high-density polyethylene (HDPE);
a main pit;
wherein the main pit is formed primarily of HDPE;
an outlet system;
wherein the outlet system is formed primarily of HDPE;
wherein the inlet system is configured to operably connect to the main pit through a direct HDPE-to-HDPE connection, the direct connection forming a seal therebetween that is at least watertight;
and,
wherein the main pit is configured to operably connect to the outlet system through a second direct HDPE-to-HDPE connection, the second direct connection forming a seal therebetween that is at least watertight.

6 more elements

A method of constructing a utility pit, the method comprising:

providing a prefabricated body for a main pit, the prefabricated body being cylindrical in shape with open ends, the prefabricated body being formed primarily of a high-density polyethylene (HDPE) material;
cutting the body to a desired length;
removing a portion of material from the body to create an opening therein;
securing a bottom plate to a first end of the body to form a direct HDPE-to-HDPE connection and thereby forming a hermetic or nearly hermetic seal between the bottom plate and the body;
removing a portion of material from a top plate to create an opening therein;
securing the top plate to a second end of the body to form a second direct HDPE-to-HDPE connection and thereby forming a hermetic or nearly hermetic seal between the top plate and the body;
cutting a first conduit to a desired length wherein the conduit is formed primarily of the HDPE material;
securing a fitting to the first portion of conduit, wherein a first portion of the fitting is formed primarily of a metal material and a second portion of the fitting is formed primarily of the HDPE material, and wherein the first portion of the fitting and part of the second portion of the fitting rest within the first conduit;
securing the second portion of the fitting to the conduit to form a third direct HDPE-to-HDPE connection and thereby forming a hermetic or nearly hermetic seal between the second portion of the fitting and the first conduit;
cutting a second conduit to a desired length, wherein the conduit is formed primarily of the HDPE material;
securing a plurality of tabs to an exterior surface of the second conduit;
connecting a flange to a first end of the second conduit, wherein the flange is formed primarily of the HDPE material;
connecting a second end of the second conduit to the top plate adjacent the opening in the top plate;
and,
positioning a cover over the flange.
