Description

[Detailed explanation of the invention] This invention is based on an artificially created slope
When carrying out turf work in ground surface greening work such as turf work, or pine pine paste work in which seeds have been glued with fertilizer, etc., the grass and seed pine may peel off due to wind and rain before germination and rhizomes take root. This relates to a stopper used to prevent the plant from drying out or withering due to scouring.

Conventional fasteners of this type include anchors made by bending the upper part of a metal rod at a nearly right angle, anchors made by cutting an elongated flat plate to form a hook on the head, and moso bamboo cut to a predetermined length and split vertically. , Mekushi, etc., which use the knot in the middle to form a hook part, are known. However, although the former is durable, it is heavy because it is made of solid metal, making it inconvenient to carry when used in large quantities, and the cost of materials is high. In addition, in the case of the latter, if the hook formed by carving the board is straight-grained or if the thickness of the joint is thin, the strength of the hook is weak and there is a risk that it will easily break off when driven. There is. Since both have a single hook portion, there is only one pressing surface, resulting in poor fixing efficiency of the unit fastener.

The present invention has been proposed in view of the above points, and has a structure in which a split groove is formed in the axial direction at the acute-angled tip of the hollow pile, and a wedge piece is inserted into the tip, and the top of the pile The gist is that a plurality of hook rods are provided at acute angles and radially with respect to the axis of the pile body.

Embodiments of the present invention will be described below with reference to the drawings.
The pile body 1 consists of a hollow body having a tapered shape or a straight line shape and having a diameter of 5 to 15 mm and a length of about 16 cm, the tip of which is sharply pointed, and a knot 11 is formed at the top. There are two or more grooves 12 at the tip of the pile body.
are provided along the axial direction.

The wedge piece 2 has a shape such that the tip of the pile expands from the split groove 12 when it receives resistance from driving the pile, and is inserted into the tip of the pile.

The hook rod 3 has an angle θ of 10 to 60 with respect to the axis of the pile body 1.
It forms an acute angle of approximately 30 degrees (30 degrees in the example shown in the third figure), has a diameter of 5 to 15 mm, and a length of 2 to 3 cm.
In 1, two or more bases are converged and integrated, and the tip 31 becomes bifurcated or trifurcated or more radially as shown in Figs. 1 and 2 and 6 and 7. It's spreading. Each hook rod tip 3
1 is preferably sharply pointed. The base of the hook rod is located at a position slightly lower than the top end 13 of the pile body 1.

Since the present invention has the above-described structure, when the grass B or seed pine is placed on the ground surface A and the stopper of the present invention is inserted or driven, the hook rod 3 comes into contact with the grass and the seed pine and further diagonally. Immerse yourself in the direction. Therefore, the grass B or seed pine is held down as if it were supported by three or more points,
Moreover, at the tip of the pile body 1, the wedge piece 2 enters the inside of the pile body due to the pressure of the soil during pile driving, and the tip of the pile body 1 enters the dividing groove 1.
Since it expands outward from 2, it does not fall out easily, preventing it from peeling off or being washed away due to wind and rain, and is stably fixed.

In the present invention, the pile body 1 has a structure in which two or more hook rods 3 are provided radially from the head. It can be manufactured using natural bamboo such as Hachiku. In addition, as shown in Figures 6 to 8, it can be molded into a shape imitating the bamboo using a synthetic resin material, and it can be molded to be lightweight and robust.
This type of fastener is practical.
