Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a river revetment synthetic mat for natural environment preservation, which is used in place of concrete products for preserving the natural environment of a seawall.

[0002]

[Prior art]

 Conventionally, concrete products such as concrete blocks have been customarily used in river revetments at locations where the river flow velocity is as low as about 2 m / sec.

[0003]

[Problems to be solved by the invention]

 When river protection is performed using concrete products as described above, the natural environment is impaired because the slope of the river is covered with a concrete layer. In addition, since heavy concrete products are handled, there is a problem that the construction is complicated, requires a lot of labor, and increases the cost of revetment.

[0004] The present invention is proposed in view of the above-mentioned problems, and its purpose is to protect natural environments, prevent erosion of slope ground, and reduce the cost of river bank protection. The point is to provide a river bank synthetic mat for environmental protection.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the river revetment synthetic mat for natural environment preservation of the present invention is provided with a hair-rooting mat having irregular voids for entangled roots of rinsed plants and vegetation, and the mat. And a root part that has irregular voids to stabilize the hair roots that extend downward through the part.The mat part and the sheet part are layered up and down in this order. Is established on the revetment slope (claim 1). The synthetic mat for river protection for natural environment according to claim 1, wherein the mat portion for laying hair roots having irregular voids is made of a porous synthetic resin material, and the sheet portion for stabilizing roots having irregular gaps is provided. It is composed of natural plant fiber such as palm (Claim 2). 2. The synthetic mat for river protection according to claim 1, wherein a fixing metal fitting fixed to each of a required number of natural stones and having a protruding tip portion is used as the hair root active mat part and the hair root stabilizing sheet part. The natural stones are settled on the follicle cultivation mat part and the follicle stabilizing sheet part is fixed on the revetment slope (Claim 3).

[0006]

[Embodiment of the invention]

 Next, the synthetic mat for river protection for natural environment preservation of the present invention will be described with reference to the embodiments shown in FIGS. A is a river revetment synthetic mat for natural environment preservation of the present invention, and the synthetic mat A is a hair root-wearing mat part 1 having irregular gaps for entanglement of hair roots of shrubs and vegetation, and a mat part 1 thereof. And a follicle stabilizing sheet portion 2 having irregular voids for entanglement and stabilization of the follicles extending downward through the mat portion 1 and the mat portion 1 and the sheet portion 2 are superimposed one on top of the other in this order, They are integrally joined.

[0007] The hair root activating mat 1 is made of a synthetic resin material such as porous polypropylene having a relatively thick layer and irregular voids in order to entangle the hair roots and activate them. On the other hand, the follicle stabilizing sheet portion 2 has a relatively thin layer thickness and a cocoon having irregular voids in order to stabilize the follicles extending downward through the follicle rooting mat portion 1. And other natural plant fibers. 3 is a natural stone, and the natural stone 3 uses as many natural stones as necessary to stabilize the structure in a range of several to a large number per synthetic mat A. 4, the base end (reverse U-shaped portion) of the inverted U-shaped fastening fitting 5 is inserted into the fitting mounting hole 4, and the solidification agent is filled into the fitting mounting hole 4, and the fastening is performed. The base end of the metal fitting 5 is integrally joined to the natural stone 3, and the distal end (bifurcated tip) of the fastening metal 5 projects downward from the lower surface of the natural stone 3.

FIG. 5 to FIG. 7 show a state in which the river bank revetment synthetic mat A for natural environment preservation of the present invention is installed on a slope. The slope ground 6 is covered with a river protection synthetic mat A for natural environment preservation, and the tip of the fastening metal 5 fixed to the natural stone 3 is passed through the hair root active mat part 1 and the hair root stabilizing sheet part 2. 6, the required number of natural stones 3 are fixed on the follicle cultivation mat part 1, the follicle stabilizing sheet part 2 is fixed on the slope ground 6, and then the roots between the natural stones 3 are fixed. Fill the living mat part 1 with earth and sand 7 (see Fig. 1), plant shrubs and plants in the earth and sand 7, entangle the follicles with the hair root mat 1, and take root. In addition, hair roots penetrating the hair root active mat portion 1 and extending downward from the mat portion 1 are entangled with the hair root stabilizing sheet portion 2 to be stabilized.

In this state, the slope ground 6 is covered with the synthetic mat A for protection of the river shore for protecting the natural environment on which rinsing and vegetation are vegetated, and the synthetic mat A is fixed by the metal fittings 5 of the natural stone 3. Since it is settled on the surface ground 6, a concrete product such as a concrete block that covers the slope ground 6 becomes unnecessary, and the natural environment is preserved. In addition, the sweeping force of the flowing water on the slope ground 6 is reduced by the synthetic mat A in which shrubs and vegetation are vegetated and the natural stones 3, so that erosion of the slope ground 6 can be prevented without a concrete product. You.

[0010]

[Effect of the invention]

 In the present invention, as described above, the slope ground is covered with a synthetic mat for river protection for natural environment preservation of shrubs and vegetation, and the synthetic mat is fixed to the slope ground with fastening fittings attached to natural stone. Therefore, concrete products such as concrete blocks that cover the slope ground can be eliminated, and the natural environment can be preserved. In addition, the riverbed synthetic mat for natural environment preservation with shrubs and vegetation and natural stones and natural stones can reduce the sweeping force of the running water against the slope ground, preventing erosion of the slope ground without concrete products.

[0011] Furthermore, a river revetment synthetic mat for protecting the natural environment is arranged on the slope ground to cover the slope ground, and a fastening fixture fixed to each natural stone is passed through the hair root active mat part and the hair root stabilizing sheet part. By penetrating the slope ground, each natural stone is fixed on the hair root mat, and the follicle stabilizing sheet is fixed on the slope ground. Filled with soil and sand, plant shrubs and plants in the soil, entangle the follicles with the hair root mat, and stabilize the follicles that extend downward through the mat. Since it is entangled with the sheet for stabilization, it is not necessary to handle heavy concrete products as in the conventional case, and the construction cost of river bank protection can be reduced.
