Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a buried sign sheet that is buried underground in order to prevent accidents caused by excavating underground objects.

(b) Prior art and its problems Conventionally, buried sign sheets (hereinafter referred to as sheets)
Several ideas have been made regarding this. Representative examples are shown below.

(1) Utility Model 45-13330 (tape-shaped synthetic resin buried object marking sheet) Utility Model 50-30801 (same as above) (2) Utility Model 49-18407 (locked with slack in the length direction) 53-34001 (folding type) 1987-18887 (built-in filament string in a curved detour) 50-5209 (folding type spot welding) 51-5212 (tearing sheet by weakened part in width direction) (extension) Utility Model Publication No. 51-27046 (surplus length roll-up) The characteristics of these ideas are listed in parentheses to the right of each number, but even when excavated mechanically with a power shovel, the sheet will stretch and come out to the surface. Therefore, it is necessary to have slack in the length direction, use tape-shaped synthetic resins or synthetic fibers that are stretchable and have high tear strength, or lay them in a folded state, or weaken them in the width direction. This shows a sheet that has a function of being torn to stretch the sheet, or a sheet that is rolled up with extra length.

These conventional embedded sign sheets are commercialized in various sizes, such as widths of 50, 100, 150, 200, 300, and 400 mm. The reason is,
This is because the size of each buried object is different, so the width of the sheet is determined accordingly.

In recent years, the size of buried objects has become larger, and wider sheets are required. On the other hand, at the end of demand, the size of buried objects is small and the sheet can be narrow. Information about the buried object, such as the manager's name, the year it was buried, and the type of buried object, are printed on the sheet in different colors, so it is desirable to manufacture sheets of various widths, but if the quantity is small. becomes uneconomical. Therefore, the current situation is to either limit the width of the sheets and use them even if the width is too wide or too narrow depending on the buried object, or to lay multiple sheets with narrow widths. and put it into practical use. In this case, the uneconomical problem of using a wide sheet for a small buried object arises, and if a narrow sheet is used for a large buried object, the original purpose of the sheet may not be achieved and an accident may occur. Furthermore, when multiple sheets are used, there is a problem with workability when burying the sheets.

(C) Means for solving the problem The buried marker sheet of the present invention has a tape-like sheet displaying information about buried objects, and has one or more cut sections that can be divided along the length. have.

(d) Examples Examples of the buried sign sheet of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a continuous piece of buried indicator sheet 2 in the form of a roll, and in this embodiment, the sheet has an indication indicating that the buried object is a gas pipe. Preferably, this sheet is made of synthetic resin or synthetic fiber. Two separable cutting parts 3a and 3b such as perforations are provided along the length of the continuous body 1 of the sheet 2 so as to divide the width of the sheet into approximately three equal parts. For a synthetic resin sheet, a thin portion may be provided linearly to serve as a cut portion.

In Fig. 2, 1a and 1b are the sheets 1 shown in Fig. 1 that are divided into two strips with a width ratio of 2:1 by cutting portions 3a or 3b, and further cut into lengths suitable for the work. The divided sheets are cut and laid over a large diameter gas pipe 4a and a small diameter gas pipe 4b, respectively. In the above embodiment, a separation line is shown that divides the sheet into three equal parts in the length direction, but it is also possible to form a sheet having cutting parts suitable for buried objects, such as dividing the sheet into two equal parts or four equal parts. Further, it is not necessarily necessary to provide a separation line to divide the sheet into equal parts as in the embodiment, but it is also possible to provide separation lines to form sheets of different widths.

(E) Effects The buried sign sheet according to the present invention can be easily divided into a plurality of pieces in the length direction, and each divided piece can be used as a sign sheet for its own purpose. That is, one type of embedded marker sheet is suitable for several types of uses, and has excellent workability, resulting in a large economic effect.
