従来より、水中にケーソン等の構造物を設置する場合などにおいて、水中の地盤に投入した捨石を錘で押圧することで均し固めて基礎を形成する水中捨石均し工法が用いられている。 Conventionally, when a structure such as a caisson is installed in water, an underwater rubble leveling method has been used in which rubble stones thrown into the ground underwater are leveled and solidified by pressing with a weight to form a foundation.

この水中捨石均し工法では、錘を上下摺動自在に装着した支柱を台座に立設した構造の水中捨石均し装置を用い、錘を台座に向けて支柱に沿って落下させることで台座で水中に投入した捨石を押圧するようにしている（たとえば、特許文献１参照。）。 In this underwater rubble leveling method, an underwater rubble leveling device with a structure in which a support with a weight slidable up and down is erected on the pedestal is used, and the weight is dropped along the support toward the pedestal to form a pedestal. The rubble stones thrown into the water are pressed (see, for example, Patent Document 1).

図１に示すように、水中捨石均し装置１は、起重機船２のクレーン３にそれぞれ独立して昇降自在に吊下げた支持体４と錘５とで構成している。 As shown in FIG. 1, the underwater rubble leveling device 1 is composed of a support 4 and a weight 5 that are independently suspended from a crane 3 of a hoisting vessel 2 so as to be able to move up and down.

そして、水中捨石均し装置１は、図２に示すように、予め水中６の所定位置に投入した捨石７の上部に支持体４と錘５とを載置し（図２（ａ））、その後、水中６で錘５だけを支持体４に沿って所定の高さまで上方に吊上げ（図２（ｂ））、その後、支持体４に沿って錘５を落下させることよって予め水中６の所定位置に投入した捨石７を押圧して均し固める（図２（ｃ））。 Then, as shown in FIG. 2, the underwater rubble leveling device 1 places the support 4 and the weight 5 on the rubble 7 which has been thrown into the water 6 at a predetermined position in advance (FIG. 2A). After that, only the weight 5 is lifted upward to a predetermined height along the support 4 in the water 6 (FIG. 2B), and then the weight 5 is dropped along the support 4 to predetermine the water 6 in advance. The rubble stone 7 thrown into the position is pressed to level and harden (FIG. 2 (c)).

この水中捨石均し装置１の支持体４は、錘ガイド体８と延長体９とを上下に着脱自在に接続した構成となっている。 The support 4 of the underwater rubble leveling device 1 has a structure in which a weight guide body 8 and an extension body 9 are detachably connected vertically.

錘ガイド体８は、図３に示すように、下部側錘ガイド構成体10と上部側錘ガイド構成体11とに分割可能に構成されている。 As shown in FIG. 3, the weight guide body 8 is configured to be separable into a lower side weight guide structure 10 and an upper side weight guide structure 11.

下部側錘ガイド構成体10は、水平な矩形板状の台座12の上部に複数本（ここでは、４本）の支柱13をそれぞれ間隔をあけて垂直に立設し、支柱13の上端部に水平な薄板状の接続体14を取付けている。 In the lower weight guide structure 10, a plurality of (here, four) columns 13 are vertically erected on the upper portion of the horizontal rectangular plate-shaped pedestal 12 at intervals, and at the upper end of the columns 13. A horizontal thin plate-shaped connector 14 is attached.

上部側錘ガイド構成体11は、水平な薄板状の接続体15の上部に複数本（ここでは、４本）の支柱16をそれぞれ間隔をあけて垂直に立設し、支柱16の上端部に水平な薄板状の接続体17を取付けている。 In the upper weight guide structure 11, a plurality of (here, four) columns 16 are vertically erected on the upper portion of the horizontal thin plate-shaped connecting body 15 at intervals, and at the upper end of the columns 16.

It can be detachably connected by fastening them with fasteners such as bolts and nuts.

この錘ガイド体８は、それぞれ上下に直線状に伸延させた複数本の支柱13,16の外側（支柱13,16の水平な外接線よりも外側）に錘５を上下に複数本の支柱13,16に沿って摺動自在に装着している。 The weight guide body 8 has a plurality of columns 13 up and down with weights 5 on the outside of the plurality of columns 13 and 16 (outside the horizontal circumscribed lines of the columns 13 and 16), respectively. It is mounted so that it can slide along 16 and 16.

錘５は、外形が矩形箱型形状となっており、中央部に上下に貫通する一つの貫通孔18を形成している。貫通孔18は、支柱13,16の水平な外接線よりも大きな水平断面を有している。なお、錘５には、上部四隅にクレーン３で吊下げるための吊下具19を取付けている。 The weight 5 has a rectangular box-shaped outer shape, and forms one through hole 18 that penetrates vertically in the central portion. The through hole 18 has a horizontal cross section larger than the horizontal circumscribed lines of the columns 13 and 16. A hanging tool 19 for hanging by a crane 3 is attached to the weight 5 at the four upper corners.

そして、錘ガイド体８は、錘５の貫通孔18を複数本の支柱13,16に挿通させている。 Then, the weight guide body 8 has the through holes 18 of the weight 5 inserted through the plurality of columns 13 and 16.
