図１に示すＦは，合成繊維で形成された網で、内部に中詰め材１を充填して使用する袋体である。中詰め材１を充填した袋体Ｆは、河川、海域、防波堤等において使用される。 A method for binding openings of a bag body according to an embodiment of the present invention will be described with reference to the drawings.
F shown in FIG. 1 is a bag formed of a synthetic fiber and used by filling the filling material 1 inside. The bag F filled with the filling material 1 is used in rivers, sea areas, breakwaters, and the like.

図２に示す中詰め材１は、例えば、割り石、割栗石、コンクリート塊等である。２は、袋体Ｆの開口部ＦＡ近傍に設けられ、開口部ＦＡを開閉する開口部開閉ロープである。開口部開閉ロープ２は、図７に示すように、例えば、袋体Ｆの網の目を一つ飛ばして、開口部ＦＡを環状に形成すると共に、開口部ＦＡの外方へと向かう構成となっている。
なお、開口部ＦＡは、例えば、図４に示す網の先端部Ｆ１を折り返して形成する（図２、図４〜図６参照）。 The filling material 1 shown in FIG. 2 is, for example, chopped stones, chopped stones, concrete blocks, and the like. Reference numeral 2 denotes an opening opening / closing rope that is provided near the opening FA of the bag body F and opens and closes the opening FA. As shown in FIG. 7, the opening / closing rope 2 has, for example, a structure in which one mesh of the bag body F is skipped to form the opening FA in an annular shape and toward the outside of the opening FA. It has become.
Note that the opening FA is formed, for example, by folding the tip F1 of the mesh shown in FIG. 4 (see FIGS. 2 and 4 to 6).

また、図３に示す３は吊り上げロープで、吊り上げロープ３は、袋体Ｆに取り付けられ、中詰め材１を充填した袋体Ｆを吊り上げるものである。
開口部開閉ロープ２の袋体１の取り付け部位Ａは、図３及び図４に示すように、吊り上げロープ３の袋体１の取り付け部位Ｂより開口部ＦＡに近い側に位置している。 3 is a lifting rope, and the lifting rope 3 is attached to the bag body F and lifts the bag body F filled with the filling material 1.
As shown in FIGS. 3 and 4, the attachment portion A of the opening / closing rope 2 on the bag body 1 is located closer to the opening FA than the attachment portion B of the lifting rope 3 on the bag body 1.

従って、図２の状態で、開口部ＦＡから中詰め材１を充填し、中詰め材１が所定量に達すると、中詰め材１を充填した袋体Ｆを吊り上げロープ３で吊り上げ、具体的には、吊り上げロープ３は、例えば、図示しないバックホウ等に取り付けられた部材の先端のフック１０に引っ掛けられて持ち上げられるようになっている（図３、図８及び図９参照）。
この吊り上げた状態で、開口部開閉ロープ２を図７及び図８の矢印方向に引っ張って、開口部開閉ロープ２で開口部ＦＡを閉じると共に、開口部開閉ロープ２で吊り上げロープ３の周囲を旋回して巻き付け（図９参照）、巻き付け後、開口部開閉ロープ２が解けないように開口部開閉ロープ２を結束する（図１参照）。 Therefore, in the state of FIG. 2, the filling material 1 is filled from the opening FA, and when the filling material 1 reaches a predetermined amount, the bag body F filled with the filling material 1 is lifted by the lifting rope 3, For example, the lifting rope 3 is lifted by being hooked by a hook 10 at the tip of a member attached to a backhoe or the like (not shown) (see FIGS. 3, 8, and 9).
In this suspended state, the opening opening / closing rope 2 is pulled in the direction of the arrow in FIGS. 7 and 8 to close the opening FA with the opening opening / closing rope 2 and to turn around the lifting rope 3 with the opening opening / closing rope 2. Then, after winding (see FIG. 9), the opening opening / closing rope 2 is bound so that the opening opening / closing rope 2 cannot be unwound (see FIG. 1).

従って、上述した袋体の開口部の結束方法によれば、開口部開閉ロープ２の袋体１の取り付け部位Ａは、吊り上げロープ３の袋体１の取り付け部位Ｂより開口部ＦＡに近い側に位置しているため、中詰め材１を充填した袋体Ｆを吊り上げロープ３で吊り上げ、この吊り上げた状態で開口部開閉ロープ２で開口部ＦＡを閉じれば、吊り上げロープ３の内側に位置する開口部開閉ロープ２には、吊り上げロープ３に比較し、中詰め材１の荷重がかからず、開口部ＦＡを容易に閉じることができ、しかも、開口部開閉ロープ２で吊り上げロープ３の周囲を旋回して巻き付け、巻き付け後、開口部開閉ロープ２が解けないように開口部開閉ロープ２を結束して、施工現場での作業性の改善を図ることができる。     Therefore, according to the method for binding the opening portions of the bag body described above, the attachment portion A of the opening / closing rope 2 on the bag body 1 is closer to the opening FA than the attachment portion B of the lifting rope 3 on the bag body 1. If the bag body F filled with the filling material 1 is lifted by the lifting rope 3 and the opening FA is closed by the opening opening / closing rope 2 in this lifted state, the opening located inside the lifting rope 3 Compared with the lifting rope 3, the opening / closing rope 2 is not subjected to the load of the filling material 1 and can easily close the opening FA, and the opening / closing rope 2 surrounds the lifting rope 3. After turning and winding, after winding, the opening / closing rope 2 can be bundled so that the opening / closing rope 2 cannot be unwound, and the workability at the construction site can be improved.
