JP3019041U - Spacer for greening work - Google Patents

Abstract

(57) [Summary] [Purpose] To function as a source of fertilizer and water for vegetation cover soil and stabilize the cover soil by making plants grow well. [Structure] A feature is that a fibrous, crushed, or powdery organic substance is solidified and integrated into a block.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The idea is to mix reinforced soil by mixing fiber yarn with earth and sand, and to cover the retaining wall, slope, and protective surface of the embankment, and to plant plants on this cover soil. Construction of greening existing mortar / concrete slopes, construction of spraying a plant growth base on the protective surface, or construction of plants by spraying soil cement on surface-disintegrating ground. In the above, the present invention relates to a spacer used to lay and lay a net on the surface of those protective surfaces.

[0002]

[Prior art]

 Conventionally, soil and sand are mixed with a solidifying material such as fibers and cement, and compacted by the discharge pressure of high-pressure air and the pressure of a rammer, etc., and the slope is covered as a mixed reinforcement soil with high density. Various greening methods are known, such as a method of planting plants on a base.

In order to float and stretch the net on the surface of the protective surface before the covering soil is constructed in this greening method, a spacer formed in a block shape with metal, concrete or plastic is placed on the protective surface, Through this, a pin driven into the ground holds it together with the net.

[0004]

[Problems to be solved by the device]

 The conventional spacers mentioned above are made of durable material that does not corrode or does not easily corrode, such as metal, concrete, or plastic, so when plants are planted on the cover soil to carry out revegetation, it is of no use for the growth of these plants. Met.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned conventional problems, this invention proposes a spacer for greening work in which organic substances such as fibrous, crushed, or powdery particles are consolidated and integrated in a block shape.

[0006]

[Action]

 Since the spacer 1 embedded in the soil cover 6 is a solidified organic material, it functions as a source of fertilizer for the growth of the plants planted in the soil and also a water source due to its high water retention capacity. Function as.

[0007]

【Example】

 The spacer 1 is formed by consolidating various organic substances such as fibrous materials such as peat moss, bark compost, bacas, and pulp meal, crushed particles, or granular materials, or by consolidating with a binder such as bentonite or a resin binder, to the center. It is formed in a block shape such as a quadrangle, a circle, a polygon having a pin through hole 2.

When this spacer 1 is used, the spacer 1 is placed on a protective surface 3 such as a retaining wall, slope, or embankment, and a net 4 is laid on the upper side of the spacer 1 in the same manner as in the conventional case. A state in which the spacer 1 is held on the protective surface and the net 4 is floated from the protective surface by driving through the pin through hole 2 of the stopper pin 5 having a hook-shaped locking portion at the upper end and driving into the ground of the protective surface 3. Lock and hold.

After that, the protective surface 3 is covered with a cover soil 6 such as a reinforced soil in which soil and sand are mixed with a solidifying material such as fibers or cement, or a spraying material, and tightened by the discharge pressure of high-pressure air or the pressure of a rammer. Harden and plant a suitable plant in this soil cover 6.

[0010]

[Effect of device]

 As described above, according to the present invention, the net is held as a block of the solidified body in a state of being floated from the protective surface during the lining work, and the organic matter constituting it is buried in the soil. In addition to functioning as a source of fertilizer for growing plants planted in cover soil, it also functions as a source of water due to its high water retention capacity, resulting in good plant growth and the propagation of roots to cover soil. The stability of can be increased.
