Field of the Invention The present invention relates to an anchor member, and more specifically, a mat body (sheet-like, such as a waterproof mat, a vegetation mat or a weed-proof mat, for reinforcing the ground, particularly soft ground, or laying on the ground. Of the above) are screwed into the ground or embedded in the ground in order to firmly fix it on the ground.

Description of the Related Art Conventionally, for fixing a mat body such as a vegetation mat laid on a slope of a river, for example, an anchor member is placed from above the laid mat toward the ground. Was driving. As a conventional anchor member, for example, a nail shape, that is, a columnar shape having a tapered tip on the driving side is formed. By using such an anchor member, the mat laid on the slope can be fixed so as not to move.
【０００３】しかしながら、時間の経過に伴って、地盤

ため、この問題を回避すべくアンカー部材における柱状
本体に返し部を設ける提案がなされた。However, with the passage of time, the anchor member driven into the ground may gradually come out, so that it has been proposed to provide a barbed portion on the columnar main body of the anchor member in order to avoid this problem.

出るという問題を防ぐことはできなかった。Indeed, by providing a return portion on the anchor member, a locking force acts in the direction in which the anchor member is going to come out, so it is possible to prevent the anchor member from coming out for the time being. However, for example, when the ground is soft or the slope of the slope is steep, the return portion does not function and the problem of the anchor member coming out cannot be prevented.

提案もされている。By the way, although the story changes, in recent years, greening movements in towns have been promoted here and there. That is, in recent years, the amount of greenery (plants) has decreased from the town and the places where people living and working there can relax are disappearing. Governments and local governments are recommending planting trees to restore the lost greenery.
It has also been proposed to subsidize companies that promote greening.

た。Therefore, the present inventor wondered if there is an anchor member that is extremely difficult to slip out even if the ground is soft or the slope of the slope is steep, and that can play a role in promoting greening. As a result of repeated thoughts and earnest studies and studies, the present invention finally came up with an anchor member of the present invention.

とになる。Then, a seedling of the plant is planted (or sown) from the upper opening of the tubular body. This seedling (or seed) begins to grow inside the tubular body, and roots begin to grow. The root seeks water and nutrients, and the tip of the root eventually comes out from the inside of the tubular body to the outside (outside of the tubular body) through the peripheral wall opening of the tubular body. As the plant continues to grow further, several roots extend to the outside and form a state in which many roots are stretched in the ground. Then, the softness of the ground is improved by a large number of roots stretched on the ground, and it becomes strong and prevents landslides and collapses, and the anchor member is firmly fixed to the ground,
It becomes very difficult to come out. Even when an anchor member is used for fixing a mat body such as a waterproof mat or a vegetation mat laid on the ground, the anchor member is firmly fixed to the ground and is very difficult to come out. The mat body will be firmly fixed on the ground.
