Abstract

A system for marking and detecting an underground utility is provided. In particular, the present invention relates to a system of risers that are each coupled to an underground utility. Additionally, a free end of each riser is indirectly coupled to an adjacent riser via a colored cable, wherein the colored cable is positioned at a predetermined height above the underground utility. Finally, the color of the cable is selected to visually identify the type of utility to which the system of risers is coupled.

Claims

1. A system for marking an underground utility, the system comprising a plurality of risers, each riser having a first end and a second end, the first end of each riser having a contact surface to be affixed to a portion of the underground utility, the second end of each riser having an interface surface for receiving a colored cable, wherein the colored cable provides a visual indication of the underground utility.

2. The system of claim 1, further comprising a predetermined distance interposed between the contact surface and the interface surface of each riser.

3. The system of claim 1, further comprising a reflector attached to the second end of each riser.

4. The system of claim 3, wherein the reflective disk is detectable via at least one of a sonar technology, a global positioning satellite technology, a radar technology, a magnetometer technology, a radiograph technology, an electromagnetic technology, and a thermal sensing technology.

5. The system of claim 1, wherein a selected color of the colored cable corresponds to a color code representative of a specific type of underground utility.

6. The system of claim 3, wherein the reflector is positioned approximately within a plane of the ground surface.

7. The system of claim 1, further comprising a stanchion having a first end and a second end, wherein the first end of the stanchion is coupled to the second end of the riser, and the second end of the stanchion extends upwardly to a position proximal to a ground surface.

8. A method for marking an underground utility, the method comprising:

providing an underground utility;

coupling a first end of a first riser to a first portion of the underground utility;

coupling a first end of a second riser to a second portion of the underground utility;

spacing the first riser from the second riser at a predetermined distance;

interconnecting a second end of the first riser with a second end of the second riser with a colored cable; and

positioning the colored cable at a predetermined height above the underground utility, wherein the colored cable provides a visual indication of the underground utility.

9. The method of claim 8, further comprising coupling a reflector to the second end of at least one of the first and second riser, wherein the reflector is detectable via at least one of a sonar technology, a global positioning satellite technology, a radar technology, a magnetometer technology, a radiograph technology, an electromagnetic technology, and a thermal sensing technology.

10. The method of claim 8, further comprising selecting a color for the colored cable, the color of the colored cable corresponding to a color code representative of a specific type of underground utility.

11. The method of claim 8, further comprising coupling a first end of a stanchion to the second end of at least one of the first and second riser, wherein a second end of the stanchion extends upwardly to a position proximal to a ground surface.

12. The method of claim 11, further comprising coupling a reflective disk to the second end of the stanchion, wherein the reflective disk is detectable via at least one of a sonar technology, a global positioning satellite technology, a radar technology, a magnetometer technology, a radiograph technology, an electromagnetic technology, and a thermal sensing technology.

13. The method of claim 12, further comprising interconnecting the first and second risers with the colored cable such that the colored cable substantially spans the length of the underground utility at the predetermined height above the underground utility.

14. The method of claim 8, further comprising coupling a plurality of risers to the underground utility, the predetermined distance being interposed between adjacent riser of the plurality of risers, wherein the plurality of risers substantially spans a length of the underground utility.

15. A device for marking an underground utility, the device comprising a riser having a first end and a second end, the first end of the riser being coupled to the underground utility, and the second end extending upwardly from the underground utility, the second end having a surface configured to receive a colored marking cable at a predetermined height above the underground utility.

16. The device of claim 15, further comprising a retention mechanism to secure the first end of the riser to the underground utility.

17. The device of claim 16, wherein the retention mechanism is at least one of a strap, a belt, a chain, a tether and an adhesive.

18. The device of claim 16, wherein the retention mechanism comprises a receiving channel into which a portion of the underground utility is inserted and retained.

19. The device of claim 15, wherein the second end of the riser further includes a compartment for receiving a reflective disk.

20. The device of claim 15, wherein the surface configured to receive the colored marking cable comprises at least one of a channel, an indent, a protrusion, a groove, a notch, a hook, a plug, a receptacle, a cavity, a striated surface and a contoured surface.

21. The device of claim 15, wherein the second end of the riser further comprises a mounting surface for receiving a stanchion, the stanchion having a first end and a second end, the first end being coupled to the mounting surface, and the second end extending upwardly to a position proximal to a ground surface.
