Description

[Detailed explanation of the idea] (Target of invention, industrial application field) This invention is used in the field of flood prevention.

The present invention relates to a pot step device that reduces the pressure of water leakage (spring water) on an embankment.

(Prior art and its problems) As a means to prevent embankment destruction due to seepage water,
There is a so-called Kamatanko (Kamatsukuri, Kamatome).

This is a construction method in which when water leaks at the top of a back step or on a flat area near an embankment, sandbags or dohyo are piled up in a circle around the leak to reduce the gushing water using water pressure.

However, in recent years, the area has become a residential area, and it has become difficult to obtain sandbags and dohyo rings.

In addition, doai bags and sumo rings are heavy, and stacking them requires a lot of manpower and time, and it may be difficult to transport depending on the location.

Therefore, there has been a desire for a device that can easily build up a pot at a water leak location.

(Purpose of the present invention) The purpose of the present invention is to provide a pot tiering device that can easily build up a pot at a water leakage point.

(Structure of the invention) The technical means of the invention taken to solve the above problems are as follows.

That is, the present invention has the following features: A frame that is separably formed and has a cylindrical shape with an opening at the bottom when assembled; A collapsible frame that covers the inner surface of the frame and has an opening at the bottom to take in leakage water; This pot tiering device consists of a water-shielding sheet; a drainage means for discharging leakage water that gushes in and rises from the opening;

(Example) The present invention will be explained in more detail based on the example shown in the drawings.

FIG. 1 is a perspective view, and FIG. 2 is a sectional view showing the state of use.

Reference numeral 1 denotes a frame body, which is composed of a required number of curved frame panels 1a, 1b, 1c, and 1d.

Mounting flanges 2 are formed over the entire height on both sides of the frame panels 1a, 1b, 1c, and 1d, and a required number of connecting holes 21 are bored in each mounting flange 2 at the same position.

The frame panels 1a, 1b, 1c, and 1d are then joined together, and a connector 3 as shown in FIG. 3 is passed through the connecting hole 21 to connect them.
c and 1d are assembled into a cylindrical shape.

Note that the frame body 1 is not limited to a cylindrical shape, but may be a rectangular tube shape. Alternatively, a cylindrical body with a bottom may be used, and in this case, a water leakage inlet is required in the bottom plate. In short, it is sufficient as long as it can support the watertight sheet 5 described later.

A drain pipe 4 is formed in the frame panel 1a as a drainage means for discharging rising leakage water.

In this embodiment, the drain pipe 4 is used as the drainage means, but a gutter may be provided at the upper end of the frame 1.

The connector 3 may be a bolt, a nut, or the like, but a connector like the one shown in the figure is preferable because it does not take much time to attach and detach.

A watertight sheet 5 is made of a flexible vinyl sheet or the like and is formed into a cylindrical shape with a bottom so that it can be stretched inside the frame 1.

A circular opening 51 is provided at the center of the bottom of the watertight sheet 5.
However, at the position of the drain pipe 4, a drain pipe 50 is provided which is integrally formed with the watertight sheet 5.

A water-shielding tube 52 that is inserted into the soil is attached to the inner peripheral edge of the opening 51, as shown in FIG.

Further, a required number of eyelets 6 are attached to the upper peripheral edge of the watertight sheet 5 at equal intervals, and the watertight sheet 5 is hung on the frame 1 via a hook 7.

This embodiment works as follows.

As shown in FIG. 4, after assembling the frame 1 so as to surround the water leak, a watertight sheet 5 is placed inside the frame 1, and a water-blocking cylinder 52 is placed so as to surround the water leak.
When inserted into the soil, water leaks into the watertight sheet 5 from the opening and rises up. The leaked water that has built up in this way is drained from the discharge pipe 4.

(Effects of the invention) As described above, the frame according to the invention can be disassembled, and the watertight sheet can be folded, so it can be stored and stored.
Easy to transport.

It is particularly effective in preventing water leakage in areas where trucks cannot enter.
