No. 8, Japanese Unexamined Patent Publication No. 4-11117, Japanese Utility Model Publication No. 62
No. 41072). In addition, a net-like sheet material for civil engineering construction work laid on the ground surface to improve the ground on a flat soft ground surface has been put to practical use. This type of sheet is generally called a civil engineering sheet. Further, in order to form a ground surface similar to a natural turf, artificial turf in which a large number of turf-like members formed or processed in the form of turf leaves are planted on a base cloth has been put to practical use. . In this kind of artificial turf, the applicant of the present application has a configuration in which a plurality of pile yarns having open free ends are planted in a braided base fabric, and a soil region binder is sprayed or filled in a base region of the pile yarn.

This is a factor that causes an increase in construction costs. In addition, this type of construction method generally requires a means or structure for preventing the outflow of vegetation material, maintenance management of vegetation material, or complicated construction management. Is done. On the other hand, conventional civil engineering sheets and artificial turf
Although the need for maintenance and maintenance can be reduced to some extent, this type of material or product is difficult to stretch on an inclined ground surface and is not generally suitable as a slope covering material. Even if the slope can be covered with a conventional civil engineering sheet or artificial turf, the civil engineering sheet or artificial turf easily expands or contracts due to aging, and is liable to cause wrinkles and tears. It is difficult to maintain a good sloped ground covering surface. Moreover, the mesh, civil engineering sheet or artificial turf requires a relatively large number of ground anchors to withstand wind and rain. For this reason, it is not suitable for construction on a hard slope such as a slope covered with concrete.

In addition, since the wound long sheet is arranged at the upper end of the slope, and the sheet is fed out, the sheet can be stretched on the slope by rolling the wound sheet along the slope. The construction process is quick and simple. Further, since the predetermined load of the load applying portion acts on the sheet as tension, it is possible to compensate for the expansion and contraction of the covering material after or at the time of construction. Further, since the slope can be repaired by replacing or repairing the long sheet, maintenance of the slope coating is easy. In addition, according to the slope coating method having the above-described configuration, by applying a sufficient load to the load applying section, the slope coating material can be held on the slope of the slope coating material for a long period of time. Slope covering work on a hard inclined ground surface such as a concrete surface can be performed relatively easily. In a preferred embodiment of the present invention, at least two parallel load applying portions are arranged parallel to a width direction of the long sheet, and a linear core material having a predetermined own weight is inserted into the load applying portion. Is done. According to this configuration, since the load of the load applying portion can be dispersed, the cross section or diameter of the load applying portion or the linear core material can be reduced, and the convenience or workability of handling the long sheet can be improved.

The two load applying portions are arranged in the lower end region of the slope, and the load applying portion located below the slope in the inclination direction is fixed to the ground surface. According to this configuration, the lower load applying section is fixed to the ground surface, and the upper load applying section is freely or displaceably disposed on the inclined ground surface. Thus, the lower load applying section permanently fixes the lower end of the sheet to the ground, and the upper load applying section applies tension to the sheet to prevent the sheet from wrinkling or the like for a long time. Note that the relatively higher load applying section may be fixed to the ground at a time when the expansion and contraction of the sheet is converged or stabilized. In a preferred embodiment of the present invention, a portion of the long sheet located at the lower end in the inclined direction of the slope is formed in a bag, and a sediment injection part is formed in the bag, and the earth and sand is formed in the injection part. To hold the lower end of the sheet substantially parallel to the ground surface. Since the earth and sand injection portion can be deformed in accordance with unevenness of the ground surface, the lower end portion of the sheet comes into close contact with the ground. In addition, you may insert the said linear core material in earth and sand injection | pouring part. In another preferred embodiment of the present invention, the long sheet is superimposed on a seam of each long sheet spaced in the width direction of the slope, thereby continuously covering the slope having a large width.

It has a tensile strength of about 0kg / 3cm. According to the slope coating material having the above configuration, a slope coating material suitable for the above-described slope coating method is provided. In a further preferred embodiment of the present invention,
The load applying sections are arranged at substantially equal intervals in the longitudinal direction of the long sheet base material. As a result, a slope coating material in which the load applying portions are arranged at substantially equal intervals is obtained. Such a slope coating material is excellent in versatility and constitutes a coating material applicable to any slope. Moreover, the above-described slope coating material can be stored as a winding roll while simplifying production management by a regularly repeated structure or arrangement, so that mass production or stockpiling of the slope coating material becomes possible.
The manufacturing cost of the slope coating material can be reduced. Further, this slope coating material can be used not only as a seam treatment material to be overlapped with a seam of the coating material, but also as a repair material for the coating material already laid on the slope. Also, since the cross section or diameter of each load applying portion or each linear core material is reduced by the dispersion of the load, the slope coating material is excellent in handling convenience and workability.
