JPS605083Y2 - flexible material sheet - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a flexible sheet of material.

A reservoir made by laying a flexible material sheet such as a rubber chute, a rubberized cloth sheet, or a synthetic resin sheet such as vinyl chloride in a hollow or unearthed pond on the land is used in various areas, such as a large reservoir for securing water resources, or It is being used for wastewater treatment ponds, etc.

In a reservoir that uses this type of flexible material sheet, when the water in the reservoir runs out, the stretched sheet may flap due to strong winds, and in some cases, the sheet set on the slope or bottom may shift.

For this reason, it is necessary to anchor the sheet in some way.

Conventionally, sandbags and the like have been placed appropriately, but there are problems in handling and management, such as damage to the sandbags, hindrance to cleaning the reservoir, and a reduction in the amount of water stored when the reservoir is small.

The present invention relates to a sheet that solves these problems.

The following is a first example of a reservoir using a flexible material sheet.
, 2, the present invention will be explained in detail with reference to FIGS. 2 and 2, but is not limited thereto.

Figure 1 is a perspective view of the reservoir (one part omitted), and Figure 2 is an enlarged detailed view of the circle lined part in Figure 1. In these Figures 1 and 2, 1 is soil, 3 is ±1 The flexible material sheet of the main body is laid or stretched in the dug part, that is, the recess 2 made in the land, 4 shows the part where the end of the sheet 3 of the main body is folded and buried in the soil, and 5 shows water. .

In the present invention, a skirt 6 is attached to the main body sheet 3, and the lower end of this skirt is formed into a bag so that a complexed vinyl pipe or the like can be passed through, and a pipe 8 is passed through this bag-shaped part 7, and this skirt is bury it inside.

Note that 9 indicates the mounting position of the skirt.

The skirt buried in the soil prevents the main seat from moving, and the seat remains anchored even in the presence of wind.

This position is determined by wind direction, sheet size, slope angle, soil quality, etc.

In addition, in the above, the skirt may be extended from the main body visible material sheet in a linear manner or at intervals, and since the pipe plays the role of resisting the pull-out force, it is not limited to the pipe and can also play the above role. Any other obstacle that can be used to achieve the goal is acceptable.

Note that the present invention is not limited to the above-mentioned reservoir, but can also be used for liquid storage tanks, gas storage tanks, etc. using flexible materials.

FIG. 3 shows these fluid storage tanks, where the imaginary line of the bag-shaped body 10 shows the case of liquid, and the solid line shows the case of gas.

Note that the same reference numerals as in FIGS. 1 and 2 indicate the same parts.

The present invention as described above has the following advantages.

- For example, in a reservoir, if the skirt portion is dug in advance before the sheet is expanded, anchoring can be done by passing a pipe through the skirt during the sheet expansion and reclamation.

Therefore, it can be easily implanted on site.

■ Simply attach the skirt to the bottom of the seat.

Therefore, there are no structures or protrusions on the exterior (water side of the reservoir).

In other words, nothing can be seen from the outside.

■ Anchor rings can be fixed with a wire.

Therefore, no strain is placed on the seat.

Also, if the position and direction of the lines are considered in the design, the sheet will not be blown around by the wind.

■ Conventionally, the end of the sheet body is bent and buried in the soil as shown in 4 in Figure 1, but when using the present invention in such a case, the end of the sheet body is folded and buried in a smaller size, that is, the excavation width is reduced. It can be made smaller.

■ Since heavy objects are not loaded on the seat due to anchoring, the seat will not be damaged.
