Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a soil bag installation device for slope edging work, which is one of the slope protection methods. The purpose is to create a continuous greenery in the horizontal direction by planting trees on the existing sloped slopes, concrete retaining walls, and concrete block masonry surfaces.

[Conventional technology]

Conventionally, when carrying out greening work on bare slopes, the applicant of the present invention had to first obtain a utility model registration.
1378470 (Utility Model No. 1378470 (1987-36594)) and Utility Model Registration No. 1592242 (Utility Model No. 1592-30061).

In the former case, the technical content is that, in the soil bag installation structure on the mortar spraying slope, the soil bag for vegetation is housed and fixed in an upward pocket that is integrally molded on the mortar spraying surface. .

The above technology shortens the construction period compared to the previous method of waiting for the mortar to harden before drilling, and it is also safer because there is no need to drill at high places or on steep slopes. Effects can be obtained.

In addition, in the latter case, in the soil bag installation structure on a mortar or concrete sprayed slope, a soil bag holding frame made of bent rigid mesh material is fixed to the slope surface with anchor pins, and the holding frame and the soil bag are installed on the slope. A soil bag for planting is housed in a pocket with an approximately triangular vertical section formed between the soil bag and the soil bag, and the slope surface excluding the top surface of the soil bag is covered with lath and mortar or concrete spraying. It is something that exists.

As a result, when using a planting material on a mortar or concrete sprayed slope, once the mortar has been sprayed, the hole can be punched out and a hole made.
Furthermore, it has the effect of eliminating the need for the laborious work of digging a depression in the ground.

[Problem that the invention attempts to solve]

However, of the above-mentioned two registered utility models, in the case where a planting work is used together with the mortar or concrete sprayed slope, the completed mortar sprayed surface is punched to make a hole, and then a depression is made in the ground. This required the laborious work of digging.

The latter solves the problems of the former, but since the soil bags are fixed to the slope individually, the greening on the slope becomes sparsely scattered.
The greening effect was not necessarily sufficient.
This point is a common problem in the former as well.

[Means for solving problems]

Therefore, in order to achieve the purpose of the invention and solve the problems of the conventional technology, the present invention has been developed to provide a soil bag installation structure for slope greening work, in which the concave arc-shaped curved surface faces inward, and a predetermined length A soil bag holding frame body consisting of a plurality of horizontally long rib nets arranged along the lateral direction of the slope is arranged in multiple stages at predetermined intervals in the height direction of the slope and fixed with anchor bolts. A predetermined distance or no gap is maintained between adjacent parts of the rib net in the step, and longitudinal beams with reinforcing bars are provided at appropriate intervals perpendicularly thereto, and between the holding frame and the slope. A plurality of soil bags for planting are housed in a horizontally elongated pocket formed in the pocket, a drainage pipe is provided at the bottom of the holding frame, and the holding frame except for the opening groove at the top of the pocket is sprayed with mortar or concrete. It is something.

[Effect]

To explain the effect based on the above means, the soil bags arranged along the horizontally long pocket between the slope support frame are formed to be smaller than the pocket, and the slope side of the pocket is arranged along the slope. The holding frame side is housed with a gap formed on the curved inner surface of the ribnet.

Therefore, when mortar or concrete material is sprayed from the outside of the horizontally long rib net to the area other than the opening of the pocket, the rib net is buried and comes into contact with the convex curved outer surface of the soil bag, forming a sprayed layer. .

As a result, at the pocket opening, the top of the soil bag filled with soil is cut open and vines, shrubs, flowers and trees are continuously planted horizontally along the pocket groove, creating a green belt. becomes. In addition, the inner surface of the mortar or concrete layer on the horizontally long rib net side forms a concave curved surface, so that
It has the effect of storing some of the precipitation that has entered the pocket.
