を繰り返すことを特徴とする。[Means for Solving the Problems] The method for attaching a sheet pile for earth retaining of the present invention is a method for attaching a sheet pile to both side walls of an excavation road. A temporary construction machine with a support device for square timbers is used, a fixing square timber is attached to the temporary construction machine, the temporary construction machine is supported at the bottom of the excavation road so that the long side faces the side wall of the excavation road, and the construction is carried out by remote control. After expanding the width of the temporary construction machine and pressing the sheet piles inserted between the temporary construction machine and both side walls against the wall surface of the excavation road, a fixing member is inserted between the square timbers for fixing on both sides, and the square timbers are held together with the sheet piles. It is characterized in that it is pressed and fixed against a wall surface, then the width of the temporary construction machine is reduced, the temporary construction machine is pulled up from the excavation road, and the above series of operations are repeated.

部が接続され、該操作部は地表に導かれる。 The present invention uses a temporary construction machine that is a rectangular frame that can be expanded and contracted in the width direction, and that has a support device for attaching a fixing square piece to the long side of the frame. As an example of the temporary machine, the long sides of the frame-like body are connected to each other by a stretchable short side, and the inner surface of the long side has a fixed part along the long side. A temporary construction machine is used, which is equipped with a support device for gripping the square plate, and is further equipped with an actuation device that expands and contracts the short sides to increase and decrease the width of the frame-like body. An operating section is connected to the temporary machine, and the operating section is guided to the ground surface.

Insert the earth retaining sheet pile from the ground surface toward the bottom of the excavation road into the gap between the long side of the temporary construction machine, the fixing square material attached to the long side, and both side walls of the excavation road. After inserting the retaining sheet pile into the entire gap, the extensible part is operated from the ground surface through the operation part, the temporary construction machine is expanded in its width direction, and the fixing square members are pressed together with the sheet pile against both side walls of the excavation road. After pressing the fixing square timbers and sheet piles against the walls on both sides until there is no loosening, the operation of the temporary construction machine is stopped, and at this point, a worker is placed to place a fixed number of square timbers between the square timbers and the sheet piles that have been pressed and fixed to both walls of the excavation road. Attach the supports and secure them so that they are stretched on both sides. When the support is completely fixed, the support device of the fixing square beam is released. Next, when the temporary machine is scaled down and returned to its original shape, the fixing squares will be removed from the temporary machine while being fixed in the pressed position, and in this state the temporary machine will be pulled up to the ground surface outside the excavation road. .

き上げる。 Side surface 2 of the excavation road formed by excavating the ground surface 1
When constructing the earth retaining sheet piles 7, the fixing square timbers 6 are first attached to the support device 11 of the temporary construction machine 10. Temporary construction machine 10 with fixing square material 6 attached
is stabilized by suspending it from the top of the excavation road to near the bottom 3 of the excavation road via the hanging fitting 12. Next, a sheet pile 7 for retaining earth is inserted into the gap 4 between the fixing square beam 6 and the excavation road side surface 2 from the excavation road outer ground surface 1 toward the excavation road bottom 3. After inserting the sheet pile 7 into the entire gap 4, the telescopic power unit 16
sends an activation signal to extend the telescoping portion 15 and widen the width of the temporary construction machine 10. As a result, the fixing square bar 6 is moved toward the left and right sides 2 of the excavation road together with the long side part 10a of the temporary construction machine 10, and the fixing square bar 6 is moved toward the left and right sides 2 of the excavation road.
And the retaining sheet pile 7 is pressed against the left and right side surfaces 2 of the excavation road. As shown in FIG. 4, the protrusions 13 provided at both ends of the long side protrude from the side ends of the sheet pile 6 to prevent the sheet pile 7 from shifting in the lateral direction. When the square timbers 6 and the sheet piles 7 are pressed until they are no longer loose, the operation of the temporary construction machine 10 is stopped, and at this point a worker is placed inside the excavation road, and the fixing machine 10 is pressed against the sides 2 on both sides of the excavation road. A fixed number of supports 20 are installed between the square members 6 and fixed so as to be stretched. After completely fixing the support 20, fixing square material 6
Release the support device 11 supporting the . Next, when the width of the temporary construction machine 10 is reduced and its shape is restored to its original shape, the fixing square material is removed from the temporary construction machine while being fixed at the pressed position. After that, the temporary machine 10 is pulled up to the ground surface.
