Description of the Related Art Since ridges in paddy fields may leak due to the activity of small animals such as earthworms and moles and weathering, the surface of the existing ridges is shaved every year, and paddy soil is laid on the walls. It was used after performing a repair work that smeared like this. However, since the repair work is hard work, a method has recently been implemented in which the surface of the ridge is covered with a ridge cover and the ridge is not required to be repaired for many years until the ridge cover is damaged.

いた。[0003] The ridge cover used here is made of a soft polymer resin such as polyethylene, and has a structure in which through holes to which eyelets are fixed are formed at both edges of a band-shaped sheet portion at equal intervals along the longitudinal direction. Is common. A method of laying the ridge cover will be described. First, while repairing the ridge as described above, grooves are dug along both sides of the ridge along the longitudinal direction, and a sheet portion is placed on the surface of the ridge. Next, anchor bolts are driven into the soil from the through holes, whereby both lower edges of the sheet portion are fixed to the lower portion of the ridge (side surfaces of the groove) and the sheet portion is brought into close contact with the surface of the ridge. Finally, the soil was buried back in the groove, and both lower edges of the sheet portion were buried in the soil, and both lower edges of the sheet portion were securely held so as not to be turned up.

A gap is formed between the groove and the side surface. For this reason, when a gust of wind blows, wind enters into the inner surface side of the sheet portion from the gap, and the state of adhesion between the sheet portion and the ridge may be deteriorated, or both lower edges may be turned up, and each time an anchor bolt is There were inconveniences in the work such as re-strike and re-hanging the ridge cover.

This is made of a soft polyethylene resin, and folds both edges in the longitudinal direction of the sheet portion 2 having a long band shape in the ridge direction outward, and heat-welds the leading end of the folded portion so that both ends in the longitudinal direction are formed. An open bag-shaped storage portion 4 is formed, and the horizontal streak 3 can be inserted into the storage portion 4.

が望ましい。The above-mentioned ridge cover 1 is laid as follows. First of all, while repairing the existing ridge to the specified shape,
Dig grooves along the longitudinal direction of the ridge 11 on both sides thereof.
Is covered with the sheet portion 2, the storage portions 4 are hung down on both sides of the ridges 11, and the horizontal stripes 3 serving as cores are inserted into the storage portions 4 and held. The inner surface of No. 2 is brought into close contact. Next, at predetermined intervals along the storage section 4 into which the horizontal streaks 3 are inserted, the substantially J-shaped anchor bolts 21 are sandwiched between the bent portions 22 so as to sandwich the horizontal streaks 3, and soil is passed through the remaining portion of the bag-shaped storage section 4. Driving horizontally inside,
The storage section 4 is brought into close contact with the side surface of the groove. Finally, the soil is buried in the groove, and both lower edges of the sheet portion 2 are buried in the soil. When the anchor bolt 21 is driven into the soil, the long rod portion 23 is located above the horizontal streak 3 and the short rod portion 24 is located below the horizontal streak 3, so that it is difficult to pull out. It is desirable.

しを行えば良い。When using a ridge cover 1 having no bag-shaped storage portion 4, that is, a ridge cover 1 composed of only a band-shaped sheet portion 2, as shown in FIG. Are wound around the horizontal streak 3 several times, and then the anchor bolts 21 are driven into the soil through the sheet portion 2 to backfill the soil in accordance with the above-described procedure.

能率を格段に向上させる効果を有する。According to the method of laying the ridge cover according to the present invention, the surface of the ridge is covered with the ridge cover, and the lower edge of the ridge cover is held along the longitudinal direction with the horizontal streak covered. The ridge cover can be brought into close contact with the surface of the ridge by the weight of the horizontal streak, and the horizontal streak is anchored by driving substantially J-shaped anchor bolts into the soil at predetermined intervals along the longitudinal direction of each edge. The lower edge of the ridge cover can be tightly attached to the lower surface of the ridge by fixing it immovably while sandwiched between the bent portions of the bolts. This eliminates the need to re-install the ridge cover or re-strike the anchor bolts, which has the effect of significantly improving the efficiency of the work of laying the ridge cover.
