<p>PROBLEM TO BE SOLVED: To provide an implement and a material for accurate and speedy burying operation since boundary stones (hereinafter "stake") are buried frequently by intuition.SOLUTION: A "stake" is buried by observing a pole with a prism through a surveying instrument and finding a boundary predetermined position. Boundary points (three places) of the "stake" are displayed by mounting two kinds of "plates" having suitable holes bored on the pole since the center of a pole is a boundary point so as to clearly show the boundary points at a hole for "stake" burying. A cube which is of life size of the "stake" and lightweight is formed, and a level and a pole insertion hole are provided at an upper part at up to three places (hereinafter referred to as "a main body"). The insertion hole of the "main body" is selected according to the position of the boundary point of the "stake" to be buried, and the pole with the prism and a case which covers a side face of the "main body" are mounted and observed to specify an installation position. The "stake" is installed at the specified position by replacing the "main body" in the "case" with the "stake" after the hole is partially backfilled with earth, extracting the "case", and backfilling the hole completely.</p> |
