SOIL RETAINING METHOD USING STEEL PIPE FOR RETAINING GROUND SOIL AND STEEL PLATE

摘要

The present invention relates to a mud construction method using a steel pipe and a steel plate for mud construction, it is possible to reduce the number of steel pipes inserted into the ground compared to the H beam pile under the same conditions, so that the clamping portion of the vibrating hammer can firmly grip the circular steel pipe It has its purpose. To this end, the present invention, (a) assembling the jig for gripping 40 in the upper center of the wing-shaped iron plate 20 having the wing portion 20a on both sides (S10), (b) mounted on the excavator After gripping the support member 13 of the steel pipe 10 with the single protruding plate 11 with the clamping part C of the vibratory hammer, inserting the steel pipe 10 into the ground (S20), (c) After the step S20, after gripping the jig 40 for gripping of the wing-shaped iron plate 20 with the clamping part C of the vibratory hammer, the wings are attached to a single protrusion plate 11 of the steel pipes 10 adjacent to each other. Step (S30), (d) fitting the wing portion (20a) of the mold iron plate 20, after the construction is completed, the clamping portion (C) of the vibrating hammer is the horizontal portion 43 of the jig 40 for gripping Hanging wing plate 20 includes a step of drawing out from the ground, the steel pipe 10 is inserted at a distance to the ground, as a circular steel pipe, the incision 12 and a part of the upper end of the steel pipe cut off, It characterized in that it comprises a support member (13) provided in the interior of the incision (12), and the protruding plate (11) that protrudes from both sides of the outer circumferential surface of the steel pipe so that the iron plate is fitted.
