Solar panel mounting stand installation method, pile and solar panel mounting stand

Abstract

A method of installing a solar panel mounting stand, the method including: forming an installation scheduled surface on which a plurality of piles are scheduled to be installed at a position deeper than an original ground surface, by digging the soil of an installation site of the solar panel mounting stand; installing the plurality of piles at the installation site by supporting the plurality of piles in a state of being relatively aligned, using a pile installation structure, and transporting the plurality of piles to the installation site of the solar panel mounting stand integrally with the pile installation structure, and placing the projecting portions on the installation scheduled surface corresponding to each projecting portion, and refilling the installation site with soil; removing the pile installation structure from the plurality of piles; and assembling a member as a framework of the solar panel mounting stand, using the plurality of piles.

1 . A method of installing a solar panel mounting stand using a pile as a supporting leg, the pile comprising: a columnar pile body, at least a lower end side thereof being buried in the soil when a solar panel mounting stand equipped with a plurality of supporting legs is installed on the ground; and a non-spiral-shaped projecting portion provided at a lower end of the pile body in a state projected in a radial direction of the pile body
 and configured to inhibit a pull-off of the pile body under a load of the soil when the lower end side of the pile body is embedded in the soil;   the method comprising:   a first step of forming an installation scheduled surface on which the plurality of piles are scheduled to be installed at a position deeper than an original ground surface, by digging the soil of an installation site of the solar panel mounting stand;   a second step of installing the plurality of piles at the installation site by supporting the plurality of piles in a state of being relatively aligned, using a pile installation structure, and while maintaining such a supporting state, transporting the plurality of piles to the installation site of the solar panel mounting stand integrally with the pile installation structure, and placing the projecting portions, which are formed at lower ends of the plurality of piles, on the installation scheduled surface corresponding to each projecting portion, and thereafter refilling the installation site with soil;   a third step of removing the pile installation structure from the plurality of piles; and   a fourth step of assembling a member as a framework of the solar panel mounting stand, using the plurality of piles.   
     
     
         2 . A solar panel mounting stand installation method according to  claim 1 , wherein
 in the second step, the pile installation structure supporting the plurality of piles, is hoisted by a crane and transported to the installation site of the solar panel mounting stand.   
     
     
         3 . A pile used as a supporting leg when a solar panel mounting stand equipped with a plurality of supporting legs is installed, comprising:
 a columnar pile body; and   a non-spiral-shaped projecting portion provided at a lower end of the pile body in a state projected in a radial direction of the pile body,   wherein at least a lower end side of the pile body is buried in the soil when the solar panel mounting stand is installed; and   the projecting portion is configured to inhibit a pull-off of the pile body under a load of the soil when the lower end side of the pile body is embedded in the soil.   
     
     
         4 . The pile according to  claim 3 , wherein
 the projecting portion is formed into a plate-like shape having a larger external size than an outer diameter of the pile body.   
     
     
         5 . The pile according to  claim 3 , wherein
 a coupling portion is provided on an upper end of the pile body, for assembling a member as a framework of the solar panel mounting stand.   
     
     
         6 . A solar panel mounting stand equipped with a plurality of supporting legs, wherein
 a pile is used as a supporting leg, said pile comprising:   a columnar pile body, at least a lower end portion thereof being buried in the soil; and   a non-spiral-shaped projecting portion provided at a lower end of the pile body in a state projected in a radial direction of the pile body, and configured to inhibit a pull-off of the pile body under the load of the soil when the lower end side of the pile body is embedded in the soil.   
     
     
         7 . The pile according to  claim 4 , wherein
 a coupling portion is provided on an upper end of the pile body, for assembling a member as a framework of the solar panel mounting stand.
