The mounting table 7 is suspended by suspension wires 9 that pass through winches 8 and 8 provided on the left and right sides, and a water-permeable bag 2 such as a nonwoven fabric or a woven fabric is placed on the mounting table 7. As shown in FIG. 1, the mounting table 7 on which the bag 3 packed with the earth and sand, which is filled with the earth and sand and the bag 2 is closed, is placed in the appropriate winch from the appropriate four points on the carriage 5 as shown in FIG. 8, and the winch 8 is used to lower the mounting table 7 toward the bottom of the water horizontally as shown in FIG. As shown in FIG. 3, the suspension wire 9 of one winch 8 of the mounting table 7 is extended, one of the mounting table 7 is brought close to the water bottom B, and then the carriage 5 is rolled up while lifting the suspension wire 9 of the other winch 8. Is moved in the F direction, the bag body 3 filled with earth and sand is slid on the mounting table 7 and is gently installed on the bottom B.
[0010]
Here, in order to smoothly install the bag body 3 filled with earth and sand on the bottom B, the hull of the carriage 5 is moved from the moment when the end of the bag 3 filled with earth and sand arrives at the bottom B. It is good to move so that it may pull on the opposite side, ie, the direction shown by the arrow F of FIG.
[0011]
In FIGS. 1, 2, and 3, reference numeral 10 denotes a fixing wire for mooring the carriage 5.
[0012]
Next, FIG.4 and FIG.5 is a schematic side view which shows the installation method in other embodiment of this invention, In this case, the mounting base 7 provided in the carriage 5 similarly to the embodiment of the said FIG. A split-type structure that can be split at the center part, the mounting table 7 in the state of FIG. 4 is lowered horizontally to an appropriate position near the bottom B of FIG. 5, and the mounting table 7 is divided into two parts at the center part as shown by the arrow S. The bag 3 filled with earth and sand on the mounting table 7 is quietly installed at a predetermined position on the bottom B. In FIG. 1 and FIG. Show.
[0013]
In the mounting table 7 described above, when the bag 2 is packed with earth and sand, etc., if the mounting table 7 is packed in the water under a certain degree of water using the winch 8 and the suspension wire 9, Due to the buoyancy, the burden on the bag 2 and the mounting table 7 due to the load of earth and sand is reduced, and the bag body can be prevented from being damaged.
[0014]
Next, FIG. 6 to FIG. 11 will be described. This is another embodiment of the present invention in which the work of filling earth and sand in the bag 2 is carried out underwater, and the equipment used in this case is shown in FIG. 6 and FIG. FIG. 6 is a schematic front sectional view thereof, and FIG. 7 is a side sectional view thereof. As shown in FIG. 7, the watertight water tank 11 is provided on the floating body 12 in the vertical penetration space 13 formed by hollowing out the central part of the floating body 12 made of a trolley or a unifloat in a rectangular shape. It is hung with the winch 14 of.
[0015]
The water tank 11 is filled with water, and a water-permeable bag 2 such as a nonwoven fabric or a woven cloth similar to that of the above-described embodiment is spread, and earth and sand injection at the end of the bag 2 in the water tank 11 is performed. Sediment or the like is injected into the bag 2 through the sediment injection hose 16 from the part or the like, and after the injection of a predetermined amount of soil or the like, the injection port is tied and sealed.
[0016]
Since the injection of the earth and sand into the bag 2 is performed in an underwater environment in the water-tight water tank 11, the tension applied to the bag 2 is only the difference in specific gravity with water compared to the case where bagging is performed on the water. The required strength of the bag 2 can be reduced.
[0017]
Next, the watertight water tank 11 is lowered toward the bottom B as shown in FIGS. 6 and 7 by the winch 14 for raising and lowering on the above-mentioned trolley or the floating body 12, and the watertightness shown in FIG. By turning the winch 15 for turning over the water tank 11 and pulling up the wire 20, the watertight water tank 11 is tilted and turned over as shown by the arrow T, and the earth and sand stuffing bag body 3 is gently lowered to the bottom B and installed. .
[0018]
FIG. 8 is a perspective view showing the floating body 12 and the water-tight water tank 11 of FIG. 6, and FIG. 9 shows that the water-tight water tank 11 of FIG. Instead, the case where the bag 3 is lowered to the water bottom B by operating the appropriate desorption device 18 from above the floating body 12 is shown at the bottom of the watertight water tank 11.
[0019]
In the embodiment shown in FIG. 6, the bag 2 is spread in two stages in the watertight water tank 11 and the soil and sand are packed in water. As shown in FIG. 10, the bag is placed in the watertight water tank 11. 2 may be expanded and packed in one bag.
[0020]
Furthermore, as shown in FIG. 11, it is also possible to increase the number of water tanks 11 positioned in the upper and lower penetrating space 13 of the floating body 12 to two or more. In this case, the water tank 11 descends to the bottom B and to the bottom of the water. The work efficiency can be improved by alternately performing the installation work of the bag body 3 for the left and right water tanks 11.
[0021]
As described above, according to the installation method described with reference to FIGS. 6 to 11, bagging of earth and sand etc. is performed in the water in the water tank 11, so that it is possible to prevent the diffusion of contaminated water generated at the time of bagging. However, instead of the watertight water tank 11, the bottom plate alone may be used, or a net-like or grid-like side surface may be provided around the bottom plate.
[0022]
Further, by changing the shape of the watertight water tank 11, the shape of the bag 3 packed in a bag can be determined as appropriate.
[0023]
Furthermore, in the present invention, if the mixture of earth and sand and solidified material such as cement is made into an unsolidified body instead of the earth and sand packed on the mounting table 7 or in the water tank 11 as described above, it is installed on the bottom B and stacked. At that time, since the mixture of the earthen sand and the solidifying material packed in the bag is solidified, the mixture of the earthy sand and the solidifying material bites into each other, and a strong mound structure can be formed.
[0024]
FIG. 12 is a side view in which a mound-like structure body is formed by orderly stacking the earth and sand stuffing bag bodies 3 on the water bottom B by the installation method according to each embodiment described in FIGS. 1, 4, and 6.

【The invention's effect】
In the method for installing the bag body filled with the earth or sand of the present invention or the mixture of earth and sand and the solidified material described above, the load is applied by adopting a mounting table or a water tank instead of hanging the bag body directly. Since it is a system that receives from below, the strength of the bag can be minimized, and an overall economical installation method can be provided.
[0026]
Further, in the present invention, a bag body filled with earth or sand or a mixture of earth and sand and a solidifying material can be accurately taken to a predetermined installation position, and can be installed quietly without the possibility of breaking a cloth bag or the like.
[0027]
Furthermore, if a mixture of bagged soil and cement or other solidified material is used as an unsolidified material, when it is installed and stacked, it is before solidification. When solidified, a strong mound structure can be formed as a whole, and once solidified, even if the cloth bag or the like is subsequently broken, there is no influence on the whole.
[0028]
Further, in the method of the present invention, since the bag body can be quietly installed on the bottom of the water, it is possible to prevent the occurrence of pollution in the water and its diffusion, and in particular, by selecting, for example, a nonwoven fabric as the bag material, Can be prevented from spreading underwater.
[0029]
In addition, according to the installation method of this invention, the bag body filled with earth and sand or the mixture of earth and sand and a solidification material can be gently installed in a predetermined position also with respect to the deep water bottom.
