Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a slope greening method.

[0002]

2. Description of the Related Art The present applicant has previously described a wire mesh on a slope,
A mesh base is formed by a plurality of coil nets extending in the horizontal direction provided in parallel in the vertical direction on the surface of the wire mesh, and a soil is used as a main component on the mesh base, a curing agent, and a greening base material. A greening base was created by spraying a greening soil mixed with A. and a planting method was proposed, in which plant seeds were sprayed on the ground (JP-B-59-40972).

[0003]

According to the above-mentioned conventional slope greening method, since a net base is interposed between the slope and the greening base formed thereon, the adhesion of the greening base to the slope is low. A strong, stable greening base can be obtained,
Since the coil net extending in the horizontal direction is provided in parallel in the vertical direction on the surface of the wire mesh, steps at regular intervals are formed on the greening base, so that it is possible to prevent the outflow of seeds and to settle the incoming seeds well. However, it is desired that a greening base such as pack linter, bark compost, and chemical fertilizer in the greening base does not flow out by rainwater and a permanent fertilizer effect is provided on the greening base.

[0004] The coil net used in the conventional slope greening method is brought to a construction site in a compressed state for convenience of transportation, and the number of nets used for the net base is stretched to the same size for construction. It is to be attached to a wire net with binding wires. However, the work of stretching a large number of compression coil networks to the same size has been troublesome and difficult due to the coil network itself having elasticity.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a greenery base in which a greenery base does not flow out due to rainwater, and in order to meet the demand for permanence of a fertilizer effect in a greenery base, and to provide a large number of compression coil networks brought to a construction site. The present invention provides a slope greening method which can be easily made to have the same size when stretched to a length.

[0006]

According to a first aspect of the present invention, a mesh base is formed on a slope by a wire mesh and a plurality of laterally extending coil nets provided in parallel in the vertical direction on the surface of the wire mesh. A slope that is formed by forming a greening base by spraying greening soil containing a soil as a main component, a curing agent, and a greening base material on the base of the net, and spraying plant seeds on the base. In the greening method, a tubular open-cell foam having a hollow portion filled with fertilizer is inserted into each of the coil networks.

According to a second aspect of the present invention, in the slope greening method according to the first aspect of the present invention, a plurality of coil nets are brought to a construction site in a compressed state, and each of the coil nets is filled with fertilizer in a hollow portion. After the insertion of the tubular open-cell foam, the compression coil network is stretched to substantially match the entire length of the tubular open-cell foam.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 2, a wire mesh (2) as shown in FIG.
A net base (4) is formed by a plurality of laterally extending coil nets (3) provided in parallel in the vertical direction on the surface of the wire net (2). The wire mesh (2) is fixed to the slope (1) by the anchor (8). In each of the coil networks (3), a hollow portion (5) is provided.
The synthetic resin tubular open-cell foam (7) filled with the fertilizer (6) is inserted in advance in the following manner. That is, the required number of coil networks (3) are brought to the construction site in a compressed state, and as shown in FIG.
A cylindrical open-cell foam (7) filled with a fertilizer (6) in a hollow part (5) is inserted into the compression coil network (3A) so that one end of the foam is open, and then the compression coil network (3A) is inserted. Attach one end to a wire mesh (2) with a binding wire (9), then open tubular open cell foam (7)
The compression coil network (3A) is stretched so as to be slightly longer than the entire length of the compression coil network (3A), and the other end of the stretched compression coil network (3A) is attached to the wire mesh (2) with a binding wire (9).

The diameter of the tubular open-cell foam (7) is 2 to 5 c.
m, the length is 2 m, and the diameter of the hollow part (5) is 0.7 ~
1.0 cm, which is almost equal to the inner diameter of the coil net (3). The length of the compression coil net (3A) is 20 cm, which is stretched to form a 2 m coil net (3). fertilizer
As (6), chemical fertilizers are used.

Each of the coil nets 3 extending in the horizontal direction is arranged on the surface of the wire net 2 with a vertical interval of 50 to 100 cm. At this time, since the tubular open-cell foam (7) is inserted into each coil net (3), both of them maintain a linear shape together, and the wire net (2) of the coil net (3) is maintained. ) Can be easily arranged.

After the formation of the mesh base (4) as described above, the coiled net (3) is sprayed almost uniformly with green soil containing the soil as a main component, a curing agent and a greening base material on the surface thereof. A stepped greening base (10) is constructed as a guest soil in which the upper part protrudes, and seeds of grass, grass, wild grass, etc. are sprayed on the greening base (10).

[0012]

According to the slope greening method according to the first aspect of the present invention, a hollow portion is formed in a plurality of laterally extending coil nets which are parallel to each other in a vertical direction on a net ground formed on the slope. Since the tubular open-cell foam filled with the fertilizer is inserted, the tubular open-cell foam has water retention, so that the greening base material in the greening base is not likely to be washed away by rainwater. Moreover, since the components of the fertilizer filled in the hollow portion of the tubular open-cell foam gradually seep into the greening base through the open cells, the conventional type that depends only on the greening base in the greening base There is much more permanent fertilizer effect compared to.

Further, according to the slope greening method according to the second aspect of the present invention, a plurality of coil nets are brought to a construction site in a compressed state, and each of the coil nets is filled with fertilizer in a hollow portion. After the foamed foam is inserted, the compression coil mesh is stretched so as to substantially match the entire length of the tubular open-cell foam. And the linear state can be maintained in combination with the presence of the tubular open-cell foam inserted in the coil net, so that the above-mentioned arrangement work can be performed reliably and efficiently.
