Description

  The present invention relates to a structure of a retaining wall greening block constructed by selecting an improved variety of Iwadaresou as a retaining wall greening plant.

  In recent years, for the purpose of greening the retaining wall, a plant planting pocket has been formed on the front part of all or part of the retaining wall block, and soil has been put into this pocket so that plants can be planted. In fact, it is also being constructed. Therefore, the problem is the maintenance of the plants after the retaining wall construction, especially the maintenance of the water supply necessary for the continuous planting of plants.

  In order to solve this problem, in Japanese Patent No. 2732201 (Patent Document 1), a water supply pipe is arranged behind the retaining wall block, and underground water from the slope is planted by this pipe. It is designed to be taken into the planting pocket. Moreover, in patent 2828028 gazette (patent document 2), the water flow hole connected to a natural ground is opened in the block front surface part in a pocket, and it is trying to obtain the water from a natural ground by this. Furthermore, in JP-A-8-128062 (Patent Document 3), a planting part is provided with a water conduit that communicates with a natural ground, and the water on the natural mountain side is guided to the plant planting part by this water conduit. ing.

  However, in any of the above patent documents, water supply or water transfer to plants is a natural water supply request that depends on the weather, and it is possible only when there is sufficient water retention in the ground, and in reality it is to plants. There is a need for artificial water supply.

  An object of the present invention is to provide a retaining wall greening block structure that does not depend on natural water supply and does not require maintenance of artificial water supply.

  In order to achieve the above object, in the retaining wall greening block structure of the present invention, in the retaining wall greening block in which the planting pocket of the plant is integrally formed on the front portion of the retaining wall block, the plant is an improved variety And a through hole is formed in the front part of the retaining wall block from the vicinity of the bottom of the planting pocket toward the natural ground side, and the root of the improved variety of Iwadareso to the natural ground side is formed in the through hole. It is characterized in that a lead pipe that leads to is attached.

  According to the present invention, the root of the improved variety of Iwadareso grows to the natural mountain through the lead pipe and directly absorbs the water of this natural mountain, so it grows without relying on natural water supply, providing artificial water supply It can be made unnecessary.

  The improved varieties were developed by Hitoshi Kuramochi, the director of the Utsunomiya University Weed Science Research Center, the co-applicant, and developed as an evergreen cold-tolerant perennial grass that does not produce seeds by improving the native varieties. The seedlings are registered as registered No. 5871, No. 16141, No. 16142 and No. 16143. And this improved varieties have the characteristics of excellent weather resistance, fertility and water retention, and in particular, have the property of rooting deeply into the ground for water. The present invention focuses on this rooting force.

  Hereinafter, the retaining wall greening block structure for exclusive use of the rock bud according to the present invention will be described with reference to the drawings. The retaining wall greening block 10 is located on both sides of the main body 1, the embedded portion 2 that protrudes from the rear of the main body 1, the planting pocket 3 that is formed on the front surface of the main body 1, and the embedded portion 2. It consists of the guiding root pipe 4 provided. The embedded portion 2 and the pocket 3 are integrally formed with the main body portion 1. A plant is planted in the pocket 3, but in the present invention, an improved variety of Iwadareso G is planted. The top surface shape of the pocket 3 is a square shape in this embodiment, but a semicircular shape or other arbitrary shape can be selected.

  A through hole 5 is formed in the vicinity of the bottom in the pocket 3 at the left and right positions of the front surface of the main body 1 toward the natural ground side. A lead pipe 4 is attached to the through hole 5. The through-hole 5 is formed in a rectangular shape in this embodiment, but it can also be formed in a circular shape or an elliptical shape, and can be formed in one place. The root guiding pipe 4 is for guiding the roots of the improved varieties Iwadareso G to the natural ground E, and the state is filled with soil in advance. The root pipe 4 is attached along the center line L of the retaining wall greening block 10, but it is also possible to attach the lead pipe 4 by inclining downward with respect to the center line L in consideration of a case where the slope is a steep slope.

  According to the retaining wall tree planting block 10, the improved variety Iwadaresou G needs regular water supply for a while after planting in the pocket 3, but its root passes through the root pipe 4 with its growth. When reaching the natural mountain E, the roots directly absorb the water of the natural mountain E. Therefore, after this state is reached, there is no need to rely on natural water supply, and there is no need for artificial water supply.

It is a top view which shows an example of the retaining-wall greening block structure only for the rock bud according to this invention. It is sectional drawing which follows the AA line of FIG. It is sectional drawing of the state which planted the improved kind of Iwadareso along the BB line of FIG. It is the schematic sectional drawing which applied the retaining wall greening block of the present invention to retaining wall construction.
