Abstract

PROBLEM TO BE SOLVED: To perform greening of a whole surface by a method wherein a rearward stretching counterfort is built on the rear surface of a front wall, and a plurality of longitudinally extending-through through-passages for vegetation are formed in a front wall. SOLUTION: A pair of right and left counterforts 2 are integrally molded in a rearward protruding state on the right and left sides of the rear surface of a rectangular plate-form front wall 1. Longitudinally extending-through through-passages 3 for vegetation are formed in the right and left sides of the upper and lower parts and the central part of the front wall 1 to form a block A for a greening retaining wall. During construction, blocks A are stacked on a foundation block B to build a retaining wall Y. After the back is filled with back-fill soil D, plants E are vegetated in soil D through the through-passages 3. When occasion demands, a support body for preventing outflow of soil is protruded from the lower side edge of the front end opening part of the through-holes 3 to prevent outflow of the soil D. Further, an eaves body for preventing inflow of rainwater is protruded from the upper side edge of the front end opening part of the through-passage 3 to prevent inflow of rainwater to the back of the retaining wall Y. This constitution, since a moisture content and nutrient are supplied from back-fill soil, raises plants in a natural state and covers approximately the whole of the retaining wall with Japanese ivy plants.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a block for greening retaining walls.

[0002]

2. Description of the Related Art Conventionally, retaining walls are constructed by stacking concrete retaining wall blocks, and the front surface of the retaining wall is
It is formed by the front surfaces of a number of retaining wall blocks, and the entire surface is exposed as a concrete surface.

[0003] In addition, a retaining wall may be constructed by stacking greening blocks capable of vegetation. However, in such greening blocks, since only vegetation is vegetated on the vegetation of the greening block, concrete is not provided. Most of the surface is exposed.

[0004]

However, in recent years, nature conservation and greening have been promoted, and it is desired that the entire retaining wall be covered with plants as much as possible.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a front wall and a retaining wall extending rearward from a rear surface of the front wall and integrally formed with the front wall. It is an object of the present invention to provide a block for a greening retaining wall, wherein a plurality of through-passages are formed.

Further, according to the present invention, a sediment runoff prevention receiver is provided on the front surface of the front wall along the lower edge of the front end opening of the vegetation passage, and the front surface of the front wall is provided on the front surface of the front wall. Another feature is that a rainwater inflow prevention eaves is protruded along the upper edge of the front end opening of the vegetation passage.

[0007]

Embodiments of the present invention will be described below.

That is, the greening retaining block according to the present invention includes a front wall, and a retaining wall extending rearward from a rear surface of the front wall and integrally formed, and penetrates the front wall in the front-rear direction. A plurality of vegetation through passages are formed, and a sediment runoff prevention receiver is provided on the front surface of the front wall along the lower edge of the front end opening of the vegetation through passage, and the upper edge of the front end opening is provided. A rainwater inflow prevention eaves protrudes along the area.

In this manner, the retaining wall is constructed by stacking the greening retaining block blocks, the backfill soil is filled behind the retaining wall, and the plurality of vegetation penetrations are filled in the backfill soil. By vegetating ivy plants and vine plants through the road, it is possible to cover almost the entire retaining wall with these ivy plants and the like.

[0010] At this time, the ivy plant and the like can supply moisture and nutrients from the backfill soil and the ground behind the soil, and can grow the vegetated plant in a natural state.

[0011] Therefore, the growth environment of the vegetated plants can be ensured well, and the labor and cost for protection and management of the plants can be eliminated.

In addition, the backfill soil can be prevented from flowing out to the front side of the retaining wall through the vegetation through passage by the sediment runoff prevention receiver, so that the retaining wall function and the growth environment of the vegetated plants are improved. Can be secured.

Further, even when rainwater flows down along the front surface of the retaining wall, it is possible to prevent the rainwater from flowing behind the retaining wall through the vegetation through passage by the eaves for preventing rainwater inflow. As a result, a good retaining wall function can be ensured.

The shape, size, number, arrangement position, and the like of the vegetation throughways, and the shapes, sizes, and the like of the sediment outflow prevention receiver and rainwater inflow prevention eaves are determined by the construction of the retaining wall Y. It can be set appropriately according to the environmental conditions of the place.
