BEARING JIG FOR MULTISTAGE PIPE AND METHOD OF PENETRATION OF MULTISTAGE PIPE
PROBLEM TO BE SOLVED: To provide a bearing jig of multistage pipe capable of preventing a multistage pipe from being drawn into the ground even when the multistage pipe is penetrated into a loose ground, and a penetrating method of the multistage pipe.SOLUTION: The bearing jig of a multistage pipe which includes plural pipes each having different diameter and which is penetrated into the ground. The bearing jig is engaged with the engaging portion which is disposed at the back-end part of a pipe which is exposed from the ground in the plural pipes. The bearing jig is abutted with the ground, and with respect to a pull-in force of the pipe, which is generated in a direction that the multistage pipe is penetrated the ground and acts a resistance force against the pull-in force by means of a reaction force which is generated between the ground and the bearing jig.SELECTED DRAWING: Figure 1
【課題】ゆるい状態の地盤内に貫入する場合でも、多段式パイプが地盤内に引き込まれない多段式パイプの支圧治具及び多段式パイプの貫入方法を提供すること。【解決手段】管径の異なる複数の管体を備え、地盤内に貫入される多段式パイプの支圧治具であって、前記支圧治具は、前記複数の管体のうち地盤から露出した管体の後端部に設けられる係止部に係止され、前記地盤に当接し、前記多段式パイプが地盤内に貫入される方向に発生するパイプの引き込み力に対して、前記地盤との間に生じる反力により、前記引き込み力に反発する抵抗力を作用させることを特徴とする。【選択図】図１
