DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating sheet having a vegetation base, in which a landscape of a dam lake or a reservoir is covered by vegetation which is exposed when the water level is lowered, thereby protecting the landscape. Things.

[0002]

2. Description of the Related Art In conventional dam lakes or reservoirs, every time the water level drops, the ground surface is continuously exposed along the water's edge, obstructing the landscape and giving viewers discomfort.

[0003]

Therefore, in recent years, in a public area such as a recreation base or a sightseeing spot, or in a park area in particular, the entire exposed surface of the ground is covered with continuous greening, and the early A solution is desired.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been proposed in order to solve the above-mentioned disadvantages, and has a structure in which two rectangular shaped sheets having different hardness are provided. Arrangement of buoyancy materials at regular intervals and enclosing buoyancy materials in two layers
A sheet, formed continuously irregular portion on one side of the sheet, on one surface having an uneven portion of the sheet, sticking vegetation for foundation vegetation or seeding already, one side end of the sheet, dam Or fixed to a high water level ground such as a reservoir
In addition, a flexible pipe is sealed near both ends of the floating sheet, a large number of fine holes are formed in the pipe, and a prosthesis is provided between the sheets along the outside of the sheet. Rope through-holes are provided at appropriate intervals. By doing so, even if the reduced water level, and also lowered lifting sheet with decreasing water level is obtained so and preserve the natural environment covering the background exposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIGS. 1 is a lower surface sheet having a large hardness,
Numeral 2 is a columnar buoyancy material arranged at regular intervals on the lower sheet 1, and the upper sheet 3 having a small hardness is superposed on the upper surface thereof to form an uneven portion and superimpose. 4 is a vegetation for foundation vegetation or disseminated already, and tensioning the upper surface of the topsheet 3.
Reference numeral 5 denotes a flexible water supply pipe, which encloses the lower sheet 1 and the upper sheet 3 near both sides where they are overlapped. And the water pipe 5, and bored a large number of fine pores, water in the sheet and vegetation for base 4 is adapted to penetrate. 6 is
A through hole for a rope that prostheses between the sheets, formed at the outer edge of the sheet. Reference numeral 7 denotes an anchor pin which is driven at appropriate intervals on a high water level shore such as a dam lake or a reservoir, and 8 denotes a rope stretched over the anchor pin 7. Reference numeral 9 denotes a hanging metal fitting, which is composed of two upper and lower pieces, and is formed in an arc portion 10 in the middle. Hanging brackets 9 are overlapped on the upper and lower surfaces of the upper side of the sheet so that the rope 8 can be inserted into the circular arc portion 10, bolts 11 can be inserted through the hanging brackets 8, and nuts 12 can be tightened to suspend the sheet. .

[0006]

Embodiment 1 An embodiment 1 of the present invention will be described. A buoyancy material 2 is arranged at regular intervals on the upper surface of a rectangular and lightweight lower surface sheet 1 having a large hardness, and an upper surface sheet 3 having a small hardness is superimposed on the upper surface to form a continuous irregular portion. Floating on
A two-layer sheet enclosing the force material 2 is used.
The upper surface of the uneven side to tensioning the vegetation for foundation 4 of vegetation or seeding already. On the other hand, on the ground with high water level such as dam lake or reservoir,
Driving anchor pins 7 at appropriate intervals,
Wrapped around the upper and lower two pieces,
The rope 8 is attached to the circular arc portion 10 of the
And the hanging metal fittings 9 are superimposed on the upper and lower surfaces of the upper side of the sheet.
Tighten it, hang it on the rope 8 and cut one edge of the sheet.
It was fixed on the ground with high water level, such as a lake or a reservoir .

[0007]

Example 2 will be described in Example 2 two have been of the present invention. the above
Near the ends on both sides of the floating sheet of Example 1, a flexible water supply pipe 5 having a large number of fine holes is sealed, and the upper end of the pipe 5 is connected to a water source. Hole 6 for rope to prosthe between sheets
Were provided at appropriate intervals .

According to the present invention, a large number of anchor pins 7 are driven into the ground at a high water level such as a dam lake or a reservoir at an appropriate interval, and a rope 8 is wound around the anchor pins 7 or fixed with metal fittings. The sheet is fixed and suspended from above through 9, and the adjacent sheet is connected by inserting a prosthetic rope into the through hole 6 and connecting the upper part of the water supply pipe 5 to a water source.

[0009]

According to the present invention, the high water level of the ground, such as dam or reservoir, which vegetation for <br/> base 4 of vegetation or disseminated already fixing the those tensioning the surface of the sheet, The surface is always full of vegetation and rises and falls in synchrony with fluctuations in the water level. Environment can be maintained. In the event that the sheet is damaged, the sheet can be easily removed from the hanging bracket 9 for suspension, and if the water level is required for a long period of low water level and the vegetation base needs water supply, the pipe 5 is used. Since water can be supplied by introducing and flowing down water, there is an effect that the growth of plants is not hindered.
