The present invention belongs to the field of construction methods of sheet bodies used for laying or covering over a long period of time.

[0002]

2. Description of the Related Art Generally, means for preventing the growth of weeds are manual weeding or mowing machines, and all of these have to be repeated every time the weeds grow. . As a means of preventing germination of weeds, application of a herbicide is known, but this has caused a problem of pollution. As a short-term countermeasure, there is a method of covering the ground surface with a polyethylene film sheet, but this involves excavating the ground, filling the side edge of the film sheet in this part, returning the soil again and fixing it Therefore, labor was required, and improvement in work efficiency could not be expected.

As a method for preventing the germination of weeds for a long period of time of about 10 years, a strong cloth such as polyester or nylon yarn is coated with a base cloth coated with vinyl chloride or the like. The slopes of cultivated land are covered and fixed. In addition, iron fence stop construction methods are known, but all of them are expensive, are not suitable for agricultural management, and have a low penetration rate.

It may be sewn with a reinforcing belt.

[0013] In the case of a sheet body to be used on a wetland, a paddy field, or a field ridge, a long perforated hole is provided at the center of the fixing device piece. In the case where the sheet itself is required to have weather resistance, for example, an ultraviolet absorber or a light stabilizer such as a benzophenone type, a salicylate type, an acrylonitrile type, a metal salt, or a binder adine type is appropriately added. . Alternatively, a sheet body using a phenol-based, amine-based, or phosphorus-based antioxidant in combination can be used for a long period of time.

A sheet containing a flame retardant is preferably used around a street or an amusement park, for example, a sheet containing a phosphorus-based, halogen-based or inorganic metal-based material. In general, a halogen compound and antimony oxide are used in combination, but a weathering agent or a flame retardant may be mixed into the sheet as required, even if the sheet is slightly more expensive. It is desirable. Examples of the composite sheet body include a sheet body in which a cross sheet is sewn on the back surface of an artificial turf, and a sheet body in which a cross sheet is sewn on the back surface of a Russell woven base fabric made of flat yarn having voids. When utilizing this, the fixing device piece can be directly attached to the cross sheet.

In the above description, the sheet member and the fixing device piece are integrated, but the simpler one is that the sheet member and the fixing device piece are separate from each other, At the tip by folding back strong tape material,
A triangular pyramid-shaped bag is formed, and the base of the bag is movably attached to the rope. In the construction, the rope is attached to the edge of the sheet against the sheet expanded at the site.
