Description

An afforestation-construction method of the existing concrete structure}

The present invention relates to the greening method of the existing concrete structure that is installed on the surface or slope of the bank or river bank slope, more specifically, collapse of the surface or slope of the river or river, etc. To prevent vegetation, the vegetation space is formed by drilling a plurality of vegetation holes having a predetermined interval and size in the existing concrete structure, and after installing a fixed net on the top of the perforated concrete structure, fix the fixed net with a pin. Natural friendly soils containing seeds of herbaceous plants such as gujeolcho, dianthus, evening primrose, pampas grass, and parasitic herb are installed in the vegetation hole, and the natural friendly soil is also installed in the upper part of the existing concrete structure. The simple method of greening existing concrete structures on slopes All.

In general, in order to prevent the collapse of eroded surfaces or slopes, erosion, earth and sand loss, etc. of concrete slopes, incisions, slopes of banks or banks, rock slopes, dikes, etc. In the case of constructing concrete revetment blocks, the concrete revetment blocks are continuously assembled together with the anchor blocks or anchor pins. They were firmly joined by fixing them together, and in the case of constructing concrete mats, concrete concrete was formed by pouring concrete on slopes such as embankments and curing concrete mats for a certain period of time.

However, the ecosystems of rivers constructed with such concrete structures have caused problems such as ecosystem destruction and environmental pollution due to their inherent natural environmental functions. Especially, slopes of rivers or rivers have high ecological productivity and diversity of species. As a part of the boundary between underwater and terrestrial ecosystems in natural stream ecosystems, the concrete linkages between the aquatic and terrestrial ecosystems will boil, causing the entire river ecosystem to be adversely affected by the extinction of rivers and river flora and fauna. do.

In order to solve the above problems, various types of revetment blocks have been devised and constructed, but where the existing concrete structures are constructed, the renovated revetment blocks are formed after vegetation space is completely removed from the existing concrete structures. Since the re-construction is required, the construction is complicated, the construction period is prolonged, and the construction cost is excessively neglected due to the problem of excessive consumption.

The present invention is to solve the above problems caused by the reconstruction of the existing concrete structure to be natural after drilling the vegetation hole having a predetermined size in the existing concrete structure at regular intervals without removing the existing concrete structure The purpose of this is to reconstruct the surface or slope so that greening can be done quickly and easily by attaching the soil to the vegetation hole.

In order to achieve this purpose, the vegetation hole is drilled at regular intervals in the existing concrete structure, and the fixing net is installed on the concrete structure where the vegetation hole is perforated, and then fixed with fixing pins, and then grass, gujeolcho, dianthus, evening primrose, pampas grass, The natural friendly soil containing the seeds of herbaceous plants such as parasitic plants is attached to the vegetation hole, and the natural friendly soil is attached to the upper part of the existing concrete structure with a thickness of about 5 to 7 cm, and then spraying management is carried out for a certain period of time. There is a characteristic.

As shown in Figures 1 to 4, the present invention provides a concrete revetment to prevent the collapse of eroded or eroded surface of slopes, slopes, banks of slopes, banks, banks, etc. The present invention relates to a simple and quick greening process for existing concrete structures such as blocks (1) or concrete mats (2). The specific greening methods are as follows.

<Vegetation hole drilling stage>

Boring vegetation holes (3) in concrete structures such as concrete revetment blocks (1) or concrete mats (2), which are already constructed, form vegetation spaces where plants can grow on the surface or slope and existing ground (4) and concrete The vegetation hole (3) is about 20 to 30 cylindrical vegetation holes (3) having a diameter of 35 to 40 mm per square meter of the existing concrete structure to secure air permeability and smooth flow of flowing water. Drill at regular intervals.

When the vegetation hole 3 is drilled, it is drilled using equipment such as an electric drill, and if the hole of the vegetation hole 3 is too much or the diameter of the vegetation hole 3 is too large, the construction of the existing concrete structure Since the stability is reduced and a part of the concrete structure is easily lost or collapsed during flooding or bad weather of the river or river, a proper number of vegetation holes 3 are drilled at regular intervals.

In addition, when the vegetation hole (3) in the existing concrete revetment block (1) when the vegetation hole (3) is drilled on the interface where the revetment block and the revetment block is in contact with each other, the stability of the concrete structure is reduced, so that the Drill the vegetation hole (3) in the center.

<Fixed Network Installation Steps>

A fixed net 5 is installed at the upper part of the concrete structure in which the vegetation hole 3 is perforated. The fixed net 5 is a ridged net made of various materials such as metal or fiber, and the upper part of the concrete structure as a whole. The natural friendly soil (6) to be mounted is fixed so as not to be swept away in bad weather, and at the same time the herbaceous plant seeds contained in the natural friendly soil (6) are grown so that the roots of the herbaceous plants (7) are entangled in the fixed net (5).
