Abstract

Information of the type, number, burying depth and direction of a pipe or other objects buried in the ground is identified on the ground surface. There is provided a buried marker comprising an identifying plate having indicia thereon and an interconnect band for interconnecting the identifying plate to the object buried in the ground. The position where the pipe or other object is buried is thus easily identified.

Claims

1. A buried marker comprising:

an identifying plate comprising indicia thereon for identifying a type, the number, a burying depth of an object buried in the ground;

an interconnect member for interconnecting said identifying plate and the object buried in the ground, and

a first lock affixing said interconnect member to said identifying plate and a second lock affixing said interconnect member to said buried object, said first lock and said second lock both being of the type comprising a plastic locking head having an insertion hole therein to receive an end of said interconnect member and a metal pawl supported therein to engage a respective end of said interconnect member.

2. A buried marker according to claim 1, wherein the indicia of said identifying plate comprises plural sets of slots which are markable.

3. A buried marker according to claim 2, wherein said interconnect member comprises a band for being affixed to said buried object at one end portion thereof and fixing on said identifying plate at the other end portion thereof.

4. A buried marker according to claim 3, wherein said identifying plate is placed on a spacer.

5. A buried marker according to claim 4, wherein said spacer has a cylindrical main body, and said main body has a through hole for allowing said interconnect band to extend therethrough and an opening in which said identifying plate is placed.

6. A buried marker according to claim 5, wherein said spacer has a recess portion in the bottom thereof and said through hole is formed in said recess portion.

7. A buried marker comprising:

an identifying plate comprising indicia thereon for providing information regarding an object buried under ground;

an interconnect strap having an extent extending between said identifying plate and said buried object;

a first locking element affixing said interconnect strap with said buried object;

a spacer comprising a main body having a recess therein and an intermediate wall within said recess, said body having a surface spaced from said recessed wall receiving said identifying plate thereon, said recessed wall having a hole therethrough for receiving said interconnect strap; and

a second locking element affixing said interconnect strap with said spacer.

8. A buried marker according to claim 7, wherein said second locking element is disposed within said recess between said identifying plate and said recessed wall.

9. A buried marker according to claim 7, wherein said identifying plate has a hole therethrough in substantial alignment with said hole through said recessed wall, said second locking member being disposed exteriorly of said identifying plate and affixing said identifying plate to said interconnect strap.
