あった。By the way, in the above-mentioned conventional method, when the ground to be excavated is a relatively loose gravel layer or boulder layer, even if the excavation is performed so that the cross section becomes rectangular, collapse occurs in the process. Therefore, a gap is created between the vertically built sheet pile and the side wall of the excavation groove. For this reason, there is a possibility that the earth and sand may collapse into the voids even after retaining the soil, causing road subsidence, and it takes time and money to take measures against it.

(A)). In this excavation, it will be dug vertically, but when the target ground is formed by the surface layer 25 and the loose gravel layer (crushed stone) 26 below it, the planned groove shape (two-dot chain line 27) Inevitably, the collapsed portion 13 that expands from the upper portion of the side wall to the middle portion is formed. When such a collapsed portion 13 is formed,
The airbag 1 is arranged in the collapsed portion 13. That is, the hanging pipe 11 is provided along the upper opening of the cut groove 21, and the string 12 is tied to the hanging pipe 11 to suspend the airbag 1 (see FIG. 4B). At this time, the other end of the air hose 7 is connected to the air injection fitting 5 of the airbag 1, and the one end side is extended so that the stop valve 8 is placed on the ground. Then, the support member 17 is installed inside the airbag 1. That is, the steel sheet pile 14 is vertically built in the wall surfaces on both sides in the longitudinal direction of the excavation groove 21 with a predetermined width, and the uprising material 15 is attached inside the steel sheet pile 14 in the longitudinal direction of the excavation groove 21. Beam 1 of uprising material 15
It is supported by pressing from the inside by means of 6. At this time, the airbag 1 is positioned in the space 18 formed between the cut groove 21 and the support member 17 (see FIG. 4C). In the illustrated example, the airbag 1 is first installed and then the supporting member 17 is installed. However, the airbag 1 and the steel sheet pile 14 are simultaneously lowered, or the steel sheet pile 14 is installed. After that, the airbag 1 may be inserted through the gap between the steel sheet pile 14 and the side wall.

させる。After connecting each air hose 7 and the main air pipe 10, the compressor 9 is driven to supply air at a pressure of 0.5 kgf / cm 2 or less, for example 0.1.
The air bag 1 is inflated into a shape corresponding to the shape of the gap 18 by pressure-feeding at a pressure of up to 0.2 kgf / cm 2 , and then the stop valve 8 is closed to seal the air and shape of the bag body 1. Are fixed (see FIGS. 1 and 4D). At this time, the inflation limit of the airbag 1 is normally controlled by visual observation because the inflation shape of the airbag 1 can be seen from the ground. In some cases, the injection time or injection pressure may be controlled. When the inflation of the airbag 1 is completed, a buried object 28 such as a pipe for overhead wire is laid and then backfilled with earth and sand 29. In this case, for example, after backfilling up to the middle of the digging groove 21 and rolling compaction (see FIG. 4).
(See (e)), the supporting member 17 and the deflated airbag 1 are removed (see FIG. 4 (f)), the remaining backfill is performed, and the compaction is performed to restore the road surface (ground surface) 30 to the original shape. Restore.

することができる。As described above, since the airbag 1 is inserted into the back side of the steel sheet pile 14 and expanded along the shape of the collapsing portion 13 of the excavation groove 21, it is possible to prevent the sediment from collapsing after retaining the soil. It is possible to prevent the collapse of the sediment around the excavation groove 21 and the subsidence of the road surface. Moreover, since the airbag 1 is formed by CR rubber vulcanization vulcanization on both sides of the nylon base cloth, it can have sufficient strength against earth pressure and can be adapted to various shapes. Then, by adjusting the lengths of the air hose 7 and the string 12 attached to the airbag 1, the airbag 1 can be installed according to the depth and location of the collapsed portion 13. Since the installation is performed when the airbag 1 is reduced in size, it can be performed in a short time and easily, and the air can be injected in a short time. Further, the main air pipe 10 can be removed after injecting air into each of the airbags 1 if the stop valve 8 is closed and the expanded shape is maintained, so that it does not interfere with piping burying work or the like. . Further, the air bleeding of the airbag 1 may be performed by opening the stop valve 8, but if the nipple 3 is removed, the air bleeding can be performed more rapidly. Further, since the connecting portion side of the main air pipe 10 to the compressor 9 is molded of rubber or the like, the compressor 9 can be installed at any place.

May be adjusted. Moreover, the string 1 is provided so as to surround the hanging pipe 11.
The two airbags 2 are tied two by two, but the airbag 1 is suspended, but a hook may be provided on the upper portion of the string 12 and hooked on the suspending pipe 11 to suspend the airbag 1. . Further, although the airbag 1 is shown as the bag body, the fluid to be infused is not limited to air, and other gas or liquid may be used in some cases.
