PROBLEM TO BE SOLVED: To provide a guide plate and a construction method for a batter pile foundation, which can enhance batter pile driving accuracy.;SOLUTION: This guide plate includes a center hole 10 for inserting a centering member, and a slit 20 for making the center hole 10 and a peripheral edge 1a communicate with each other. The centering member is relatively moved in such a manner as to be guided into the slit 20 from the lateral side of the centering member and lead to the center hole 10, so that the center hole 10 can correspond to the center of the batter pile foundation. Thus, the slit 20 for making the center hole 10 and the peripheral edge 1a communicate with each other is provided. The center hole 10 can correspond to the centering member through the slit 20 without the removal of a string, as the centering member is suspended by the string, and the batter pile driving accuracy is increased by virtue of an increase in the positional accuracy of the center of the batter pile foundation.;COPYRIGHT: (C)2009,JPO&INPIT
