Abstract
A surveying spike is described which includes a single nail portion and an end portion; the end portion is attached to the nail portion and coaxial therewith. The end portion has a body portion, and a reference surface forming portion projecting radially from the body portion and having a reference surface formed thereon parallel to the axis of the end portion. The reference surface has a dimple formed therein. When the surveying spike is driven into a vertical surface, the reference surface may then be horizontal and the dimple may receive a vertical pole; this facilitates surveying using EDM (electronic distance measurement) techniques. The surveying spike may advantageously be manufactured by providing a metal nail portion and a plastic end portion, and inserting the nail into the end portion.
Claims14
A surveying spike comprising:
- a single nail portion having an axis;
- and
- an end portion having a longitudinal axis, said end portion being attached to said nail portion and being coaxial therewith, and said end portion having a body portion and a reference surface forming portion projecting radially from the body portion, the reference surface forming portion having a reference surface formed thereon parallel to the axis of said end portion, the reference surface having a dimple formed therein.
A casing through which a nail is inserted to form a surveying spike, said casing having a longitudinal axis along which the nail is inserted, said casing comprising:
- a body portion;
- and
- a reference surface forming portion projecting radially from the body portion,
- wherein the reference surface forming portion has a reference surface formed thereon parallel to the longitudinal axis, and the reference surface has a dimple formed therein.
A method of manufacturing a surveying spike, comprising the steps of:
- providing one metal nail;
- providing a plastic member having a longitudinal axis and having a body portion and a reference surface forming portion projecting radially from the body portion with respect to the axis, the reference surface forming portion having a reference surface formed thereon parallel to the axis, the reference surface having a dimple formed therein;
- and
- inserting said nail into said plastic member along the longitudinal axis.
A surveying marker assembly, comprising:
- a surveying spike, said surveying spike comprising:
- a nail portion having an axis, and
- an end portion having a longitudinal axis, said end portion being attached to said nail portion and being coaxial therewith, and said end portion having a body portion and a reference surface forming portion projecting radially from the body portion, the reference surface forming portion having a reference surface formed thereon parallel to the axis of said end portion, the reference surface having a dimple formed therein;
- and
- an information tag adapted for being coupled to said surveying spike.
