Summary:PROBLEM TO BE SOLVED: To provide a branch line anchor for supporting a branch line of preventing a utility pole from falling on the ground in which a test pit hole of the minimum range excavated to survey presence or absence of a buried object is used as a burying hole of the branch line anchor, and thereby the working hours are shortened and the work labor is reduced, and also the efficiency of probe work is promoted to exhibit a necessary anchor performance.SOLUTION: A branch line anchor has a buried body for receiving the upper loading pressure by the excavated soil back-filled while being placed on the bottom face of a test excavated hole to survey the presence or absence of the buried object as the preliminary work to bury the branch line anchor of a utility pole, and a resistor for receiving the side earth pressure by being driven into the ground from the bottom face of the test excavated hole after surveying the presence or absence of the buried object in probe inspection from the bottom face of the test excavated hole to the driving depth of the resistor. The resistor is driven in a range of probe inspection from the bottom face of the test excavated hole, while coupling a connecting member for connecting the buried body, the resistor and the branch line.SELECTED DRAWING: Figure 1 【課題】電柱の倒伏を防止する支線を地盤に支持する支線アンカであって、埋設物の有無を調査するために掘削した最少範囲の試験掘穴を支線アンカの埋設穴として利用することにより、作業時間の短縮化及び作業労力の軽減化を図ると共に、探針作業の効率化を図り、必要なアンカ性能を発揮することができる支線アンカ及び支線アンカの施工方法を提供する。【解決手段】電柱の支線アンカを埋設する事前作業として埋設物の有無を調査するために掘削した試験堀穴の底面に載置した状態で埋戻された掘削土によって上載土圧を受ける埋設体と、試験掘穴の底面から抵抗体の打込み深さまで探針検査で埋設物の有無を調査した後に試験掘穴の底面から地中に打込むことで側面土圧を受ける抵抗体とを有し、埋設体と、抵抗体と、支線を接続するための連結部材とを結合した状態で、試験掘穴の底面から探針検査の範囲に抵抗体を打込むようにした。【選択図】図１
