Abstract

PROBLEM TO BE SOLVED: To provide a vegetation and planting method for existing surface portions with a short time period and slight labor at a low cost for construction without requiring peel off of existing block bodies or mortar to reconstruct, with respect to the method for vegetating, planting and greening the surfaces of existing revetments or slopes built with mortar or concrete. SOLUTION: A coating treating agent layer 3 is formed to a relevant existing surface portion 1 by spraying water-stop coating treating agent mixed with a waterproof material and silica to the whole of the surfaces of existing surfaced portions built with mortar or concrete to a revetment, slope or the like, a plurality of anchors 4 are placed at predetermined intervals leaving the anchor head portions of a predetermined height at the existing surface portion coated with the relevant coating treating agent layer 3, then cohesive coil 6 is laid until the relevant anchors are hidden in the existing portion, then cohesive soil 6 is laid so as to make the irregular surface of the existing surface portion 1 uniform, metal wire net 2 or the like is tensioned to the surface where the cohesive soil 6 is laid, a borrow material or a thick base material 8 is sprayed to a predetermined thickness thereby covering the whole of the existing surface portion.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for vegetation planting and greening existing revetments and slopes laid with mortar or concrete.

[0002]

2. Description of the Related Art Conventionally, the revetments and slopes of many rivers and irrigation canals have been entirely covered by block bodies, concrete and mortar construction, with the main purpose of protecting the surfaces. And since the purpose of the construction means is to protect the revetment and slopes, the revetment and slopes have no water retention capacity during rainfall or rising water, and the water of rivers and irrigation canals increases and rivers flood. Was a factor.

On the other hand, since the revetment and slopes are covered with a block body or mortar construction, the environment is not an environment where plants can prosper or organisms can live. As a result, the living environment on the waterside was not a moist and comfortable environment for humans, animals and plants.

[0004]

To perform plant vegetation or planting at an existing location where blocks or mortar has been constructed on seawalls or slopes, the existing block or mortar once constructed must be peeled off. The construction has to be re-performed, which has the problem that the construction period, labor and cost are required.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and has the following structure. The first invention to be patented is to spray a waterproofing coating agent mixed with a waterproofing material and silica sand on the entire surface of the existing surface where the revetment and slopes are laid with mortar, concrete, etc. Forming a coating agent layer on the existing surface portion, and placing a plurality of anchors at predetermined intervals until the head of the existing surface portion coated with the coating agent layer has a predetermined height. Then, lay the cohesive soil so that the anchor is hidden on the existing surface portion where the anchor is cast, and the uneven surface of the existing surface portion is uniform, and a wire mesh net or the like is laid on the surface where the cohesive soil is laid. This is a vegetation planting method for the existing surface portion, wherein the soil or the thick layer base material is sprayed to a predetermined thickness so as to cover the entire existing surface portion.

Therefore, it is not necessary to peel off the existing surface on which mortar, concrete, or the like is laid, and to perform the re-installation, and it is possible to easily perform plant vegetation or planting on the existing surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vegetation planting method for an existing surface according to the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional side view showing a state in which a vegetation planting method is applied to an existing inclined surface, and FIG. 2 is a sectional view taken along line AA in FIG.

In the drawing, reference numeral 1 denotes an existing surface portion laid with mortar, concrete, or the like on a ground surface B such as a seawall, a bank, or an inclined surface, and the existing surface portion 1 is usually formed with a convex portion 2 in block units. . The coating treatment agent layer 3 is formed by spraying the waterproofing treatment agent mixed with a waterproof material and silica sand on the entire surface of the construction surface where vegetation and planting is performed on the existing surface portion 1. Silica sand kneaded with the water-stop coating agent forms fine irregularities on the surface of the existing surface 1 of mortar or concrete, and when the cohesive soil is laid in a later process, the cohesive soil has a frictional resistance. It is easy to settle and the work is safe and easy. As the waterproof material, a silicate-based coated waterproof material or the like is preferable.

Reference numeral 4 denotes an anchor, and a plurality of the anchors 4 are cast at predetermined intervals on the existing surface 1 coated with the coating agent layer 3. The length of the anchor 4 is about 20 cm and its head is inverted U
It is bent in the character-shaped portion 4a. And, at the time of the casting, the inverted U-shaped portion 4a, which is the head portion, is cast about 5 cm so that it remains on the ground surface.

Reference numeral 5 denotes a partition stabilizer formed in the shape of a strip, which has a width of about 4 to 5 cm and a length of 1 m8.
It is formed around 0 cm. As shown in FIGS. 1 and 2, the partitioning stabilizer 5 is installed in a length direction orthogonal to the inclined existing surface 1. Then, the partition stabilizer 5 is wrapped around the inverted U-shaped portion 4a, which is the head of the anchor 4, and is placed and installed together with the anchor 4, so that the partition stabilizer 5 is installed simultaneously with the installation of the anchor 4. When the cohesive soil is laid on the inclined existing surface portion 1 which is a subsequent process, the cohesive soil does not flow out, the construction is easy, and the cohesive soil can be laid uniformly. .

Reference numeral 6 denotes a cohesive soil, which is laid on the surface of the existing surface portion 1 on which the anchor 4 and the partition stabilizer 5 have been cast. The viscous soil 6 is laid so that the head of the anchor 4 cast together with the partition stabilizer 5 is hidden and the uneven surface of the existing surface 1 is uniform. In this case, if the viscous soil 6 is laid based on the width of the partition stabilizing material 5, the viscous soil 6 can be laid uniformly even if the uneven surface of the existing surface portion 1 has a variation.

Next, a wire mesh net 7 or other net material is stretched on the surface on which the viscous soil 6 is laid, and the soil or the thick base material 8 is sprayed thereon to a predetermined thickness. Thick layer substrate 8
Has a thickness of about 3 cm.

[0013]

The first invention for which a patent is sought is a waterproof coating treatment agent obtained by kneading a waterproofing material and silica sand on the entire surface of an existing surface where a seawall or an inclined surface is laid with mortar, concrete, or the like. To form a coating agent layer on the existing surface, and a plurality of the coating agent layers are spaced at predetermined intervals until the head of the existing wall surface coated with the coating agent layer has a predetermined height. The anchor is hidden, and the anchor is hidden on the existing surface where the anchor is installed, and the clay is laid so that the uneven surface of the existing surface is uniform, and a wire mesh net or the like is laid on the surface on which the clay is laid. Is stretched to spray a soil or a thick layer base material to a predetermined thickness so that the existing surface body is covered.

Therefore, it is not necessary to peel off the existing surface on which mortar, concrete, etc. are laid on the revetment or on the slope, and to re-perform the work. And planting can be easily performed.
