Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a palm mat used in a greening method of a hillside slope, which is performed to prevent surface slippage, falling rocks, rain cracks, etc. on the hillside slope and to beautify the hillside slope.

[0002]

[Prior art]

 As such a palm mat, the present inventor has already provided a palm mat for a greening method on a mountainside slope disclosed in Japanese Utility Model Registration No. 3013809 (hereinafter, this palm mat is referred to as a “conventional palm mat”).

[0003] A conventional palm mat is formed by forming a large number of cuts extending horizontally through the palm mat.

[0004] In the present specification including the claims of utility model registration, the "horizontal direction" of the palm mat means a direction in which the palm mat becomes horizontal when the palm mat is laid on the hillside, and the "vertical direction" of the palm mat. Means a direction perpendicular to the horizontal direction.

A conventional palm mat is used in a greening method on a hillside as follows.

(1) The palm mat is hung on the slope, and the palm mat is fixed to the slope with an anchor pin while being pulled downward. In this case, a number of cuts formed in the coconut mat in the horizontal direction are each pulled in the vertical direction, and are opened in, for example, a substantially elliptical shape, a substantially circular shape, or the like, to form through holes.

(2) A wire mesh is put on the palm mat, and the wire mesh is fixed to the slope through the palm mat with an anchor pin.

[0008] (3) Spraying the properly blended seeds on the slope from above the wire mesh.

(4) The wire mesh, the palm mat and the anchor pin are fixed by spraying mortar composed of the cement and the mixed solution from the wire mesh with a spraying machine.

(5) The seeds sprayed on the slope germinate and grow inside the palm mat having a water retention ability, and extend upward through the through holes of the palm mat 1.

[0011]

[Problems to be solved by the invention]

 However, the conventional palm mat has the following problems.

(A) When the palm mat is fixed to the slope with the anchor pin, the cut of the palm mat may not be uniformly opened due to the unevenness of the slope.

(B) After fixing the palm mat to the slope with an anchor pin, a wire netting must be placed on the palm mat, and the wire net must be fixed to the slope with the anchor pin through the palm mat. In other words, the palm mat and the wire mesh must be separately fixed to the slope, which is a double effort.

The present invention has been made to solve the above-mentioned problems in the conventional palm mat.

[0015]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention fixes a wire mesh on the palm mat in a state where the cut is opened by pulling up and down a palm mat formed with a large number of cuts penetrating the palm mat from front to back in a horizontal direction. The purpose of this project is to provide a palm mat for revegetation on a mountainside slope. That is, the palm mat for the greening method on the hillside slope of the present invention is a palm mat in which a number of cuts penetrating the yam mat on the front and back are formed in the horizontal direction, and the cuts are opened by pulling the palm mat up and down. And a wire mesh fixed on the palm mat.

[0016]

[Action]

 In the palm mat according to the present invention, since the wire mesh is fixed on the palm mat in a state where the cut is opened by pulling in the vertical direction in advance, even when the palm mat is fixed on a sloped surface, each cut is uniform. It is kept open. In other words, regardless of the unevenness of the slope, the palm mat has a uniform through hole by each cut.

Since the wire mesh is fixed on the palm mat in advance, the palm mat and the wire mesh can be fixed to the slope at a stroke.

The seed sprouts sprayed onto the slope from above the wire mesh freely extend upward through the through holes of the palm mat.

When the palm mat is pulled in the vertical direction, the palm mat is deformed in a zigzag shape as shown in FIG. 6, but by fixing the wire mesh on the palm mat in this state, the yam mat is fixed in this deformed state. You. The palm mat that has been deformed in this way prevents the sprayed seeds and sediment from escaping, and also prevents the slope from falling due to freezing in winter.

[0020]

[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings. The reference numeral 1 is a palm mat. The palm mat 1 is made of palm fiber in the same manner as a conventional palm mat. In the coconut mat 1, a large number of cuts 3, 3,... Each cut 3 is preferably formed in a straight line. The length of each cut 3 is, for example, 26 cm. However, the length of each cut 3 is not limited to this dimension and is arbitrarily determined according to the state of the hillside slope, the type of plant to be grown, and the like. Is what is done.

The wire mesh 9 is fixed on the palm mat 1 with the cuts 3, 3,... Opened by pulling the palm mat 1 in the vertical direction.

A number of cuts 3 formed in the palm mat 1 in the horizontal direction are each pulled in the vertical direction to open in, for example, a substantially elliptical shape, a substantially circular shape, etc., to form through holes 3a, 3a,. 3, see FIG. 5).

The elongation percentage of the palm mat 1 in the vertical direction is, for example, about 20%, and the size of each through hole 3a is, for example, 15 cm in length and 21 cm in width.

The wire mesh 9 is fixed on the palm mat 1 by a binding iron wire as an example.

The shape of the mesh of the wire mesh 9 is, for example, a tortoiseshell shape or a rhombus shape.

Next, an example of the greening method of the hillside slope performed by using the palm mat 1 of the present invention is shown below. (1) The palm mat 1 to which the wire mesh 9 is attached is hung down on the slope 5 and is fixed to the slope 5 with the anchor pins 7, 7,.

(2) Spraying the properly blended seeds onto the slope 5 from above the wire mesh 9. As the seed, for example, pampas grass, mugwort, clover and the like are preferably used. The seeds may be sprayed on the slope 5 before the palm mat 1 is laid.

(3) The mortar 11 composed of the cement and the mixed solution is sprayed on the wire net 9 by a spraying machine. The spray amount of the mortar 11 is, for example, 3 to 10 kg / square meter.

(4) The seeds sprayed on the slope 5 germinate and grow inside the palm mat 1 having a water retaining ability, and extend upward through the through holes 3a, 3a... Of the palm mat 1. The one indicated by reference numeral 13 in FIG. 8 is a growing plant.

[Effect of the invention]

 As described above, in the palm mat according to the present invention, the wire mesh is fixed on the palm mat in a state where the cut is opened by pulling in the vertical direction in advance, so that the perforations by each cut are more uniform with the wire mesh. Is fixed in the open state. Therefore, even when the coconut mat is fixed to the uneven slope, each cut is maintained in a uniform opening state. In other words, regardless of the unevenness of the slope, the palm mat is provided with a uniform through hole by each cut.

Since the wire mesh is fixed on the palm mat in advance, the palm mat and the wire mesh can be fixed to the slope at a stroke. That is, the double labor of separately fixing the palm mat and the wire mesh to the slope is eliminated. Therefore, the cost of installing palm mat on the slope is reduced.
