2. Description of the Related Art At present, it is very difficult to perform general underwater blocking work, for example, when constructing structures such as bottoms of pedestals, breakwaters, and connections between quays that are installed underwater in bridges that cross rivers. As shown in FIG. 8, the connecting structure between the quay walls is divided between both quay walls 45 by a main pile 40 that is preliminarily installed, and then an iron wire 41 is used to bind the thin sub pile 42 and each main pile 40 together. A certain area is surrounded by the cobblestone 43 and the earth and sand 44, and asphalt is laid on the cobblestone 43 and the sand 44 to create a road surface for pedestrians or vehicles to pass through. Structure There are the following points.

[0003]

[Problems to be solved by the invention]

1. Difficult to construct: main pile 40 and sub pile 4
The installation of 2 not only requires the diver to dive into the water to install or tie it down, it not only requires diving equipment, but also the diver has to dive, which is highly dangerous outside the water. At the iron wire 41,
The work of fixing the sub-pile 42 is generally difficult due to the water obstruction, and the labor cost is also high as a whole.

[0004] 2. Structure is unstable: each pile 40,
Since there is a considerable gap between 42, each pile 40,
The sand 44 and the cobblestone 43 part surrounded by 42 are washed away by water, the sand 44 is washed away from the gaps between the piles 40 and 42, and the gap between the cobblestones 43 becomes large. As a result, the asphalt-filled road surface originally fell down due to the fall of the boulders 43, and the amount of sediment 44 that was washed away was different. The asphalt that has been laid flat and has a different height,
Pedestrians or vehicles may become unsafe and, to a great extent, the asphalt may fall too steeply into the water, causing it to be washed away entirely.

3. The transportation cost of the cobblestone 44 and the earth and sand 43 is high: the cobblestone 44 and the earth and sand 43 have to be dug up from a distant production site and transported to the construction site, so that not only the transportation cost of the truck is burdened, but also the cobblestone 44 However, the cost for digging out the soil 43 must be added, and the overall cost becomes considerably high.

Accordingly, in view of the above-mentioned many drawbacks, the inventor of the present invention makes the construction of the water blocking work more convenient and faster, and reduces the cost to achieve the economical efficiency. Based on many years of experience of the inventor himself who was in charge of such construction, we hope that we will develop a new design and obtain the most economical construction method with the simplest structure,
After a long period of research, I was finally able to submit an invention that met the above criteria. BEST MODE FOR CARRYING OUT THE INVENTION Hereafter, in order to understand the structure, features and other objects of the present invention, the following description will be given with reference to the optimum embodiment and drawings.

To do.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 and 2, reference numeral 10 designates a sack, and the whole sack 10 has a long bag-like structure knitted with a braided material of plastic such as PP and PE, and the gap between the bags is very large. It is small and allows only a small amount of water to pass through it, and can reliably block the sand contained in it. Among them, the practice structure of the present invention, which is commonly used in the deep sea, has one end of the sunken bag 10 sealed and the other end provided at the sand inlet 11, which is close to the sand inlet 11 of the sunken bag 10. The side wall is provided with a water outlet 12 having a small diameter, which is used for discharging a large amount of water, and the sand inlet 11 and the water outlet 12 are provided with binding rings 13 and 140 that surround the openings. 140
In addition, tie strings 131 and 142 are attached to tie rings 13 and 14, respectively.
There is an opening 130, 141 which is provided for passing through 0, and an extra long tie string 131 is passed through the opening 130 and pulls it of the user to pull the tie ring 13, 140 and the sand inlet 11 or the water outlet 12. It is convenient to change the caliber, and the sand inlet pipe 20 and the water absorption pipe 30 at the outer edge of the edge with the protruding edge
When they respectively extend into the sand inlet 11 and the water outlet 12, they are pulled firmly with the binding string 131 of each of the binding rings 13, and the diameters of the sand inlet 11 and the water outlet 12 are set to the edges 21 of the sand containing pipe 20 and the water absorbing pipe 30, Tighten it tightly to 31 and at the end, tie it down and fix it.

The sunken bag 10 is bent inward from the periphery of the sand inlet 11, and a sand retaining net 14 for covering the drainage outlet 12 is extended toward the drainage outlet 12, so that the sand-filled pipe 2 is provided.
When the sand is drawn into the bag 10 from 0, the sand stop net 14 is impacted by the sand containing water and pressed against the opening of the water absorption pipe 30, and is not sucked into the water absorption pipe 30, and only a large amount of water is absorbed. Is extracted from the water absorption pipe 30 through the sand blocking net 14,
The submerged bag 10 is filled with earth and sand.

The present invention can be installed directly on the surface of the water in combination with a sand sucker and an installation ship. As shown in Fig. 1 and Fig. 5, it installs a sand sucker on the upstream side of a river that constructs a water blocking structure, and the sand sucker sucks up the sediment at the position where it exists, and a sand-filled pipe. And send it to the stationary ship, and the stationary ship transports the sinker bag to the place where it is to be installed, and further connects the sinker bag 10 to the openings of the sand-filled pipe 20 and the water absorption pipe 30, respectively, and activates the sand sucker boat and the pump, Sediment heavier than water gradually enters the bag 10, and the closed end of the sunken bag 10 is naturally submerged in water, but when the sunken bag 10 is turned sideways,
After the closed end of the sunken bag 10 has sunk to the river bottom, the sunken bag 10 is moved so that the length of the sunken bag 10 corresponds to the distance between the two banks, as shown in the drawing. After the closed end sank to the bottom of the river on one of the banks, the deferred ship simultaneously sent sand into the sunken bag 10, and at the same time, gradually moved to the other beach, and when the sand suction was completed, the sand inlet 11 of the sunken bag 11 Tie string 13
1 and then pull the extra tie string 131 with a stationary ship to immerse the sunken bag 10 sideways into the water, or make the sunken bag 10 in a vertical form and remove the extra tie string 131 at the sand inlet 11. It suffices if they are firmly fixed to each other on the shore or the adjacent sunken bags 10, and if they are deposited, a water blocking structure having a solid structure can be formed. Alternatively, it can be directly used by pedestrians.

Further, as shown in FIGS.
The water discharge port 12 and the sand inlet 11 can be provided at both ends of the sunken bag 10, and the sunken bag 10 can be used in a sandbar. At the time of use, first, a shallow groove is dug at a suitable place on the sandbar, and then the sunken bag 10 is placed horizontally so that it extends along the shallow groove. Suck seawater and sand into the sunken bag 10. At this time, the earth and sand plunge into the submerged bag 10 due to the strong transport force, and the attached water is flown to the water discharge port 12 at the end, and the water suction pipe 30
Is discharged from the bag 10. Among them, the water absorption pipe 30
The sand stop net 14 folded back inside the water outlet 12 due to the wind pressure generated during the water extraction causes the water outlet 1
Since it is folded toward 2, and the water outlet 12 is covered, the sediment in the sinker bag 10 does not enter the water absorption pipe 30, and only water is sent to the water absorption pipe 30 through the sand retaining net 14 and settles. As it is discharged to the outside of the bag 10, the inside of the submerged bag 10 is filled with earth and sand, which is used as a water blocking wall when landfilling a landfill. As shown in FIG. 6, when making a landfill in a shallow sea bay 1, the sunken bag 10 is placed directly at an appropriate place in the sea bay to enclose a landfill area 2 in an appropriate area, and the nearby sand is sucked into the sunken bag 10. After a few water bags 10 are piled up and a strong water stop wall is formed, sand and stones are further landfilled and plants capable of holding soil are planted to form a sea bay landfill.

The present invention can also be used for making roads underwater. As shown in FIG. 7, it is possible to distribute several sunken bags 10 on both sides and use the sand suction method to soak the sunken bags 10 together.
Fill the inside with sea sand, form two banks first, and
A path is formed by filling the soil between the two banks and laying asphalt.

[0014]

As described above, according to the structure design of the sunken bag, the present invention surely has the following advantages. 1. Easy and easy to construct: At the time of construction, it can be put into water at the same time as the sand filling work of the sunken bag by simply moving together with the sand sucker ship and the deferred ship, and used to install a breakwater on the shore. It is even more convenient if you do not need to install a stationary ship, pull a sand-filled pipe on the shore with a simple trolley, and place it horizontally on the shore directly during the sand filling process of the sunken sacks. There is no need to combine the two, and construction is simple and easy. 2. The structure is stable: the sunken bag itself is made by the weaving method and is used for filling sand, but its narrow gap allows only water to pass through, but the sand is not washed away and is blocked in it.
When the whole bag is filled with sediment, the bags will be in a soft form, and when they are piled up or pressed against each other, they will fill the gaps with each other, resulting in a tighter overall structure, and the sediment will be washed away. It is possible to secure the flat state of the top surface without the risk of falling and creating a gap. 3. Low cost: The manufacturing cost of the structure of the sunken bag itself is lower than the cost of other piles that are normally used originally, and it is not necessary to use a diver or equipment to set the sunken bag, and it is used inside the sunken bag. The earth and sand is the earth and sand in the vicinity of the water, the acquisition of it is extremely convenient and not far away, there is no need for high transportation cost and acquisition cost of earth and sand material, the overall construction cost is very low, and it is surely effective. You can improve. 4. At the same time, you can clean up the accumulated sand on the bottom of the water. When the present invention is adopted, the sand accumulated on the bottom of the water can be directly sucked up and used, and the sand of the bottom of the water, which originally has no use, or even drastically raises the leech of the ship,
Accumulated sand that obstructs the route can be removed, and sand at the bottom of the water can be used as waste. 5. INDUSTRIAL APPLICABILITY The present invention can be used for construction of dikes underwater, is suitable for burying sandbars, burying banks, laying passages, etc., and can greatly enhance the convenience of use.
