A signpost for displaying positions of underground pipes in a new town is provided to prevent elimination of guiding characters and diagrams formed thereon by using a cover. A base block(10) includes an upper plate(12), a lower plate(16), and a rubber plate(14) inserted between the upper plate and the lower plate. Anchor holes(18) are formed at both ends of the base block. The base block is buried under the underground by anchors(50) penetrating the anchor holes. A signpost(20) is separably coupled with the base block in order to display a burial path buried under the underground on the surface thereof. A cover(30) is used for covering the signboard. |
