  A first embodiment of the present invention will be described with reference to FIGS. In FIG. 1, A indicates a civil engineering package, and the civil engineering package A is a structure such as a river bank such as sandy land or a levee body attached to a coast (offshore levee, mixed levee, vertical revetment, etc.). It is laid down below, and is generally constituted by a bag body 1, a partition member 2, and a filler 4. In the present invention, sand or the like refers to sand or gravel or a mixture thereof, and sand or the like refers to ground formed by sand or the like.

  The bag body 1 is filled with a filler 4 described later, and is formed of a net material. The material of this net | network material should just be excellent in intensity | strength, elongation, and shear resistance, for example, is formed with polyester, nylon, vinylon, polyethylene, a polypropylene, polyaramid, carbon fiber etc.

  Further, the knitted net of the net material may be any one that does not easily break or unravel at the time of production, construction, and after construction of the civil engineering package A. However, it is preferable to use a Russell net in consideration of shock absorption and difficulty of unraveling.

  The mesh shape may be any shape such as a triangle, a quadrangle, a hexagon, or a rhombus, as long as the shape of the bag body can be maintained and the shear resistance is excellent. In view of the above, it is preferable that the shape is a quadrangle, and the size thereof is such that the filler 4 can be held so as not to spill out.

  The partition member 2 is provided so as to traverse the inside of the bag body 1 and divides the inside of the bag body 1 into a plurality of small chambers 3, 3,... Here, the reason why the bag body 1 is partitioned by the partition member 2 is that the small chamber 3 is formed so that the bag body 1 cannot be constricted, and suction of sand or the like through the constricted portion does not occur. In addition, since the material, structure, and mesh shape of the net | network material of the partition member 2 are the same as that of the above-mentioned bag body 1, detailed description is abbreviate | omitted.

You may do it by the method.

  Then, as shown in FIG. 2 (b), for example, the above-described bag body 1 is inserted and fixed in a standing frame W, and the filler 4 is put into each small chamber 3. In this charging, although not shown, the charging material 4 may be inserted by inserting the charging material 4 into the opening of the bag body 1. Moreover, it is more preferable that the filler 4 put into the bag body 1 is in a close-packed state in terms of preventing compressive deformation of the civil engineering package A.

  Then, as shown in FIG. 2 (c), the bag body 1 is closed with a lid body 11 formed of the same netting material as that of the bag body 1. (Shown) may be bound through a mesh, or may be performed by other methods such as heat welding if the bag 1, partition member 2, and lid 11 are formed of a heat-welding resin. .

  Incidentally, as shown in FIGS. 1 to 3, the bag body 1 may be provided with hanging rings 5, 5,... At appropriate positions on the corners of the bag body 1 and other outer peripheral portions.

Further, in order to facilitate the handling of the end packaging 8, crane lifting rings 83, 83,... May be provided at appropriate positions on the outer periphery of the exterior member 81. In addition, since the structure of the net | network material of the exterior member 81, the structure of a filler, and the filling method are the same as the thing of Example 1, detailed description is abbreviate | omitted. The end package 8 and the civil engineering package A (B) can be connected through, for example, a connecting rope (not shown) to the mesh of both mesh members.

  Here, the particle diameter of the end filler 82 in the end package 8 is larger than the particle diameter of the filler 4 in the civil engineering package A (B). This is to increase the settling speed of the end package 8, and the explanation of the function and effect will be described later.

  Next, a method for laying the civil engineering package A (B) and the waterbed laying article C as described above will be described with reference to FIGS. FIG. 9 shows the laying process of the civil engineering package A (B) and the submarine laying object C by a crane ship. For example, one end of these is hung on the hook of the crane, and the other end opposite to the one end is connected. It is lowered to a predetermined location on the bottom L, and laid on the bottom L so as to be habituated.
