照）。2. Description of the Related Art As a slope covering method for covering an exposed surface of a slope, a slope construction method is known in which a mesh is laid on the slope and a vegetation material including seeds is sprayed from above the mesh.

No. 8, Japanese Patent Laid-Open No. 4-11117, and Japanese Utility Model Publication No. 62-
No. 41072). In addition, a net-like sheet material for civil engineering and construction work that is laid on the ground surface to improve the ground on a flat and soft ground surface is put to practical use. This type of sheet is generally called a civil engineering sheet. Furthermore, in order to form a ground surface similar to that of natural grass, artificial grass made by planting a large number of grass-like members molded or processed in the form of grass leaves on a base cloth is put to practical use. . In this type of artificial turf, the applicant of the present invention has a structure in which a plurality of pile yarns having open free ends are planted in a braided base fabric and the base region of the pile yarns is sprinkled or filled with earth and sand binder.

は、適していない。However, the conventional slope construction method using a net-like body and vegetation material requires a spraying process using construction equipment such as a spraying device, which lengthens the construction period and This is a factor that causes an increase in construction costs. In addition, this type of construction method requires means or structure for preventing the outflow of vegetation material, maintenance management of vegetation material, or complicated construction management, so that construction workability or workability is generally hindered. To be done. On the other hand, conventional civil engineering sheets and artificial grass are
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 generally not suitable as a covering material for slopes. Even if the slope could be covered with a conventional civil engineering sheet or artificial turf, the civil engineering sheet or artificial turf is likely to expand or contract or deteriorate due to aging, easily causing wrinkles or tears, and thus for a long period of time. It is difficult to maintain a good sloped ground covering surface. Moreover, the mesh body, civil engineering sheet, or artificial grass requires a relatively large number of ground anchors to withstand wind and rain. Therefore, it is not suitable for construction on a hard slope such as a slope covered with concrete.

の利便性又は作業性を向上させることができる。According to the above configuration of the present invention, the load of the load applying portion extending in the width direction of the slope causes a substantially uniform tension along the inclined surface to act on the long sheet, and It is stretched and withstands rolling due to wind and rain. Further, the wound long sheet is placed at the upper end of the slope, and while the sheet is being fed out, by rolling the wound sheet along the slope, the sheet can be stretched on the slope, The construction process is quick and simple. Further, since the predetermined load of the load applying portion acts on the sheet as a tension, it is possible to compensate the expansion and contraction of the covering material after or during the construction. Furthermore, since the slope can be repaired by exchanging or repairing the long sheet, maintenance of the slope coating is easy. Further, according to the slope coating method of the above configuration, by applying a sufficient load to the load applying portion, since it can be held on the slope of the slope coating material for a long period of time, it is difficult to place a ground anchor. Slope covering work of a hard sloped 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 the width direction of the long sheet, and a linear core material having a predetermined self-weight is inserted into the load applying portions. To be done. With this configuration, the load of the load applying section can be dispersed, so that the cross section or diameter of the load applying section or the linear core can be reduced, and the convenience or workability of handling the long sheet can be improved.

One load applying part is arranged in the lower end region of the slope, and the load applying part located below the slope in the inclination direction is fixed to the ground surface. According to this configuration, the lower load applying portion is fixed to the ground surface, and the upper load applying portion is arranged on the inclined ground surface so as to be movable or displaceable. Thus, the lower load applying portion permanently fixes the lower end portion of the seat to the ground, and the upper load applying portion applies tension to the sheet to prevent the occurrence of wrinkles and the like in the sheet for a long period of time. The relatively higher load applying section may be fixed to the ground when the expansion and contraction of the seat have converged or become stable. In a preferred embodiment of the present invention, the portion of the long sheet located at the lower end of the slope of the slope is formed in a bag, and the bag is provided with a soil and sand injection part, and the sand and sand is injected into the injection part. And hold the lower end of the sheet substantially parallel to the ground surface. Since the earth and sand injection portion can be deformed according to the 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 the earth and sand pouring part. In another preferred embodiment of the present invention, the long sheets are superposed on the joints of the long sheets spaced apart in the width direction of the slope, thereby continuously covering the slope having a large width.
