It has an elongation of ~ 450% and has the advantage that it fits on the laying surface due to the excellent elongation of the sheet even when it is used, for example, on surfaces with severe irregularities. However, if there is a pointed object such as a rock or a split stone on the laying surface, there is a problem that stress concentrates on a portion in contact with a tip portion of the pointed object and the sheet is torn.

いる。The above-mentioned base fabric impervious sheet is applicable, for example, to landfill soil that could not withstand the conventional sheet, and resists the earth pressure of the landfill sand due to the action of the high-strength base cloth. are doing. Therefore, when the above-mentioned base fabric-containing water-impervious sheet is used on a laid surface that has irregularities and has a sharp angle, there is an advantage that tears are unlikely to occur, but the elongation is inferior due to the base fabric and it fits on uneven surfaces. The problem of lack of sex has been pointed out.

盤,4は海を示す。Fabrics used in civil engineering and marine engineering include nonwoven fabrics, short-fiber woven fabrics, and long-fiber woven fabrics. For example, high-strength synthetic resins of medium to low elongation are used.
A woven fabric woven to about 100 to 1500 g / m 2 is used.
These fabrics have the property of high breaking strength, and are mainly used as construction materials for harbors, rivers, roads, railways, etc., as scouring prevention materials, suction prevention materials, soft ground stabilizing materials, or mud prevention materials. As shown in FIG. 3, it is laid on the ground 5 to withstand the weight of the landfill 2 and the like from above, and fulfills the function of the impermeable sheet 1. In FIG. 3, 3 indicates the ground and 4 indicates the sea.

となってしまう。The thermoplastic fibers constituting the woven fabric are 40 at room temperature.
The stress at% elongation needs to be 1.0 to 2.0 g / d or less, and is preferably 1.25 to 1.75 g / d. 80 at room temperature
The stress at% elongation needs to be 1.5 to 3.9 g / d, particularly preferably 2.95 to 3.45 g / d. If the stress at 40% elongation and / or the stress at 80% elongation of the thermoplastic fiber is too small, elongation in the weaving process is likely to occur, and a warp tension trouble occurs. While 40%
If the stress at the time of elongation and / or the stress at the time of 80% elongation is too large, sufficient elongation at break cannot be obtained, resulting in a woven fabric with poor elongation.

望ましくない。In particular, when used as a base fabric for a water-impervious sheet, the size of the mesh of the base fabric (the portion of the hole surrounded by the warp and the weft) is 10 mm.
0 mm 2 / mesh or less is preferable, and if it is too large, the effect of compounding as a base fabric cannot be sufficiently exhibited, and the tip of the pointed object easily penetrates from the eye and easily damages the water barrier sheet, which is not desirable. .

The results are as shown in Tables 1 and 2, and FIGS. 1 and 2 show the respective SS curves. The uniaxial tension was measured by the JIS L-1096 labeled strip method. When the woven fabric was laid on the side or bottom surface of the marine landfill as shown in FIG. 3 and soil was put on it, it fitted to the uneven surface as shown in FIG. 4 (b), and there was no breakage due to the sharp objects.

The tensile strength and elongation in the uniaxial direction of the base-containing cloth impermeable sheet were examined in the same manner as described above. The results are as shown in Table 3. The base fabric was stretched together with PVC, and as a result, showed a breaking strength slightly higher than that of the base fabric alone.
