The present invention relates to a streetlight foundation structure and, more specifically, to a streetlight foundation structure easy to construct, relocate, and demolish, having no necessity to form a grounding structure as a steel pipe on the ground is connected to the underground, and capable of checking a subsidence degree of a site where the structure is buried. The streetlight foundation structure according to the present invention includes: the steel pipe having the outer circumference wherein multiple stud bolts are joined; a column unit formed by placing concrete around the steel pipe to expose both end of the steel pipe at a predetermined length and of which a lower part is formed with a predetermined length and a diameter; a concrete body having a head unit of which a cross sectional diameter is larger than that of the column in the upper part and a taper unit formed in the middle part to be tapered to connect the column unit and the head unit and formed into a structure which becomes narrower to the lower part from the upper part; multiple anchor bolts embedded in the concrete body and partly protruding from the head unit; and a line pipe connected to the steel pipe by penetrating through one lateral surface of the taper unit. The streetlight foundation structure is grounded by the lower part of the steel pipe. In addition, the streetlight foundation structure is capable of checking the internal state of the site where the structure is buried by inserting a measurement means inside the steel pipe. |
