側根切り部分に土砂を埋戻す。The first invention comprises the following steps. First, a root cutting B having a predetermined depth, that is, a depth corresponding to the rooting depth of the cloth foundation, is formed on the ground A, and laying sand is laid on the root cutting bottom,
Alternatively, waste concrete is poured and the liner 1 is installed on it. This liner 1 is a double-sided rail 2 with an L-shaped cross section.
Are connected by a connecting member 3, and an upper portion of the connecting member 3 has a reinforcing bar receiving portion 4, and a rising edge 5 and a receiving rail 2 form a groove shape and are arranged at predetermined intervals in the length direction. The bottom of a scrap frame 6 made of a precast concrete plate or the like with ribs is fitted to the inside of the receiving rail 2 to establish it, and the earth and sand are immediately buried in the outer root cutting portion of the scrap frame 6.

Then, the previously assembled column base rebar D is installed so as to cover the anchor bolt 10 drilled on the footing concrete 8, and the liner 1 is installed. Underground girder rebar cage C is installed with the ruler as a ruler, and underground girder rebar cage C and column base rebar D
And are connected using a grout coupler 11, then a scrap frame 6 is established around the grout coupler 11, the upper part of is connected with a stopper 12, the outside of the scrap frame 6 is backfilled, and then between the scrap frames. Place concrete.

著しい。EFFECTS OF THE INVENTION The present invention is constructed as described above, and the scrap frame also serves as the earth retaining sheet pile, and after the root cutting, the scrap frame is dropped from the top and immediately backfilled. Since it is not assembled at first and it is dropped in the first assembly, the root cutting width can be minimized except for the connecting work space of the rebar basket, and the amount of root cutting is also small, and in combination with the front assembly of the reinforcing bar, labor saving on site work The conversion is remarkable.
