Abstract

PURPOSE:To keep properly moistened conditions all the time by providing water-collecting and draining side trenches with plates having shoulder side walls having through holes, which are set by positioning its through holes upwards by inclining it toward the hip side, on the hip side of the tree-planting base. CONSTITUTION:A trench for side trench 3 is excavated in the contact point between the berm portion 2 and the rear portion of a slope 30, and the bottom 8 of a tree-planting base slightly inclined toward the side trench 3 connectedly to the trench for the side trench 3 is formed. Through holes B are drilled in the lower part of the side wall of the side trench 3, and a water-stop plate 4 inclined toward the rear side is provided to both ends in the longitudinal direction of the side trench 3. The side trench 3 on which the plate 5 is placed by positioning the through holes A upwards slantly along the slope of the water- stop plate 4 is embedded. A water-permeable layer 7 of gravels is formed on the bottom 8, soil is placed on the layer 7 to form a growth base 6 for shrubs, etc., and a mat 10 is covered on the surface of the base 6. The decaying and drying of roots can thus be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for creating a foundation for planting layered trees on a slope, and is particularly effective on hard slopes where it is difficult to plant trees.

Traditionally, greening has been difficult, especially on mortar sprayed slopes and rock slopes...i
Attempts have been made to improve the landscape of the slope by planting I trees by effectively utilizing the dog run area on slopes with FF slopes. These are done by simply digging a hole or groove in the Inuzashi area, adding soil and planting, and then adding soil and planting in a U-shaped groove made of concrete. .

The above method is an excellent idea in that it attempts to effectively utilize the Inuhashiri area to grow plants, but since the ground forming the Inuhashiri area is impermeable hard soil or rock, it is difficult to use during the rainy season. Rainwater flows into the holes or grooves, resulting in excess water, which causes root rot, and during dry seasons, the trees often die due to lack of water supply from the ground.

The present invention was invented by focusing on the problems of root rot due to excessive water and death due to dryness in the conventional planting methods described above. The purpose is to provide a method to keep the body hydrated.

The configuration of the present invention will be explained below based on the drawings.

FIG. 1 is a cross-sectional view showing an embodiment of the present invention. To explain this, a groove for burying a side ditch is excavated near the contact point between the slope surface (JO runner section 4 and the foot of the slope section).

When excavating this trench for filling side ditches, at the same time, excavate a continuous trough so that the bottom surface of the planting base is horizontal or slightly lower on the drainage ditch side.

After excavation, a through hole (B) is provided at the bottom of the shoulder side of the side ditch ■, and a through hole (B) is made so that it touches the bottom surface of both longitudinal ends of the side ditch.
A water stop plate (ψ) is installed which is inclined to be lower towards the foot of the slope within an angle range of 0' to 90'', and a plate (51) with a through hole (Al) is installed on one side along the slope of the water stop plate. Continuously bury side ditches made of concrete or steel, etc., with a hole at the top to collect drainage. Create a planting base partially at the Inuhashiri section (2) or at the foot of the slope. In some cases, sides 1 and q having the drainage function are used only in areas adjacent to the planting base, and are used in conjunction with regular drainage ditches.

After burying and installing the side ditch, a permeable layer (7) is formed by laying shari or palm mat in the groove part excluding the side ditch, that is, at about 20 am below the planting base.

Next, soil, organic compost, soil improvement materials, etc. are appropriately mixed and filled on top of it to form a growth base (1) and L1.
After filling with soil, etc., plant azaleas, pine trees, etc. Once the planting is completed, the effect of the method of the present invention will be even better if a mat (ρ) such as strawberry or shading net is stretched over the planting base to prevent the filled soil from being washed away by rainfall. Become.

If the present invention is implemented as described above, if there is rainfall, the water flowing down from the slope will be on the side γl'! J, flows through the triangular part formed by the plate with through holes and the side gutter wall, and as the flowing water increases, it flows into the hollow part of the side gutter through the through hole in the plate, and the water stop plates at both ends of the side gutter flow. The water that flows down the slope, which is stored by the holes in the side gutter and supplied to the planting base, is muddy water that contains clay and sand due to slope erosion, and the water that flows down the slope is muddy water that contains clay and sand due to slope erosion. The triangular shape that is formed makes it difficult for mud and earth to accumulate in the gutters because the water depth is deeper and the flow speed is faster.

The holes in the planks are located at the top of the slope, allowing the muddy water to flow in and preventing dirt from accumulating in the gutter cavities.

In addition, rainfall permeates through the planting base (6) and reaches the permeable layer and the bottom of the planting base (6), and flows into the cavity of the side gutter from the through hole (B) of the OI groove, and excess water has a through hole. Root rot due to excess water will not occur because it flows out through the through holes in the plate (5), and during the dry season, water is stored in the cavity formed by the side m), the plate with the through holes, and the water supply temporary. Since water is gradually supplied to the growing substrate, the planted trees no longer die due to dryness.
