摘要

PROBLEM TO BE SOLVED: To provide an auxiliary tool for pressing-in a soldier beam capable of preventing a soldier beam from leaning with almost no human power and pressing-in safely, accurately and attractively, in pressing-in the soldier beam in an earth retaining construction by a hydraulic jack into an underground.;SOLUTION: An auxiliary tool 20 for pressing-in a soldier beam comprises: a body portion 21 whose tip 21a in a lengthwise direction is curved to an inner side; an inner side piece portion 22 protruding from an inner side face at a base end portion 21b side with respect to a halfway in the lengthwise direction of the body portion 21 and fixed along a width direction; and a ground pressure receiving portion 23 outwardly protruding from an outer side face at a further base end portion 21b side of the body portion 21 and extending along the width direction. Pressing-in of a soldier beam 11 by a hydraulic jack is initiated in a state where the auxiliary tool 20 for pressing-in a soldier beam all of whose parts are formed of steel materials and are integrally fastened is diagonally inserted into a lower side of a lower end of the soldier beam 11, while an inner side face of the tip 21a of the body portion 21 is made to be in contact with a lower end edge portion 11d at a side face 11c side opposite to a side face 11b being in contact with a laid iron plate 10, of a lower end 11a of the soldier beam 11 vertically positioned and held in a ground surface 1.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2019,JPO&INPIT
