In the separation wall of the road, the inside of the separation wall is formed of a core by assembling a vessel-like member having a through-hole on a surface; earth is filled inside the vessel-like member; the vessel-like member is mutually fixed; and the earth is put on for covering the core. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention belongs to a technology of a separation wall such as a guard rail or a separation fence for a central separation band for separation from a road.

Separation between roads or between roads and areas other than roads is made by guardrails or separation walls. As disclosed in Japanese Patent Publication No. 2003-176512, such as guardrails and Japanese Patent Publication No. 2003-220658, a reinforcing fiber in which foam resin is filled inside and the surface is impregnated with resin in order to absorb an impact with a car There has been a proposal of a shock absorbing material coated with. Both of them have landscape problems, especially normal guard rails are not sufficient to absorb the impact of a car colliding, and sometimes the guard rail damaged by the impact becomes a weapon and damages or gets on the car. May hurt people.

Patent Publication 2003-176512 Patent Publication 2003-220658

The present invention resides in the proposal of a separation wall that is covered with green and absorbs the impact caused by a car collision.

The present invention is a separation wall for separating roads and areas other than roads and roads, and the interior of the separation wall includes a container-shaped member having a through hole on the surface as an assembly core, and the interior of the container-shaped member. Is a separation wall of a road filled with soil, container-like members fixed to each other, and covered with soil so as to cover the core.

Since the present invention is a separation wall having a container-like member having a through hole on the surface filled with soil, the shape of the separation wall is maintained, and the soil is integrally connected from the surface to the core of the separation wall. Because of this, plants are easy to grow on the surface of the separation wall.
By fixing the container-like members to each other, in the case of an accident in which a car collides with the separation wall, impact resistance and shock absorption are also improved, reducing human and physical damage.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is an illustration of a conceptual diagram of a separation wall according to the present invention.
As shown in FIG. 1, the separation wall is (1) a container-like member whose core is filled with soil, assembled vertically and horizontally. A through hole is provided on the surface of the container-like member, and the soil in each container-like member is connected to the surface. (2) Each container-like member is fixed to each other. The fixing means may be an existing joint or a through hole of a container-like member, and may be a bar or a pile penetrated so as to connect the through holes. (3) The core is covered with soil.

The container-like member is not limited to the rectangular shape as shown in FIG. 2, and may have a shape in which a taper is provided on the side surface and stacked in a nested manner.
Even if the top can be covered, there is no problem.
If the surface through-hole has a size of about 1 to 10 cm and rain water that has fallen on the surface of the separation wall penetrates and the root of the plant to be grown can enter, there is no problem in its function. Considering the ease of manufacture and strength of the container-like member to be used, the number, size and shape of the container as long as it does not impair the penetration of rainwater and the growth of plant roots, regardless of the size of the above-mentioned through holes. Can be decided.

The fixing method of each container-like member can use the male-female joint which connects the container-like member which touches each other. An example of a joint is shown in FIG. In the figure, a male-female joint is provided directly on the container-like member, and a male joint is provided on the two side surfaces that contact each other, and a female joint is provided on the other two side surfaces that contact each other. Further, a male joint may be provided on one diagonal line on the upper side, a female joint on the other diagonal line, and a joint paired with the joint provided on the upper side may be provided on the bottom surface. Further, an independent joint member may be used instead of the one provided directly on the container-like member. In any case, an existing one can be used.
Or you may arrange | position a stick | rod or a pipe so that the through-hole of a container-shaped member may be penetrated.

The surface of the core portion made of the container-like member is covered with soil, and the surface can be planted by sowing or spraying seeds of flowers as necessary.
As shown in FIG. 4, it is also possible to cover the separation wall and prevent the soil on the surface from peeling off. The net may be a wire net or a fiber net.

The material of the container-like member is preferably an injection-moldable plastic or stainless steel from the viewpoint of ease of handling and ease of manufacture.

It is a conceptual diagram which shows the cross section of the separation wall which is this invention. It is a conceptual diagram which shows the example of the container-shaped member used as the core of the separation wall used for this invention. The example of the container-like member which provided the joint in order to connect a container-like member mutually is shown. It is a conceptual diagram which shows the cross section of the separation wall which covered the net | network on the surface. It is a conceptual diagram which shows the guardrail which is the conventional separation wall.
