Abstract

PURPOSE:To prevent the degradation of soil subgrade by a method in which the legs of a metal net frame are set on sloped natural ground, cement mortar layer is formed on the ground, and a vegetating material containing seeds is packed into the space formed by the metal net frame on the ground. CONSTITUTION:Given spaces are formed on sloped normal 1, metal nets 3 are laid, and many metal net frames 4 are attached to the nets 3 by binding. The frames 4 used are ones having many legs extending downwards from their lower edges. The frames 4 are temporarily covered by a covering material, e.g., corrugated cardboard, Kraft paper, etc., and cement mortar is sprayed onto the ground 1 exclusive of the places where the metal net frames 4 are set to form a cement mortar layer on the ground 1. After the mortar layer is dried, the covering material is removed out of the frames 4, and humus along with a vegetating material containing plant seeds is packed into the spaces formed by the frames 4 on the ground 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for greening slopes that simultaneously achieves reinforcement and greening of slopes and is useful for environmental preservation. [Conventional technology] In order to reinforce the slope of a ground, there is a method of spraying mortar onto the ground from a wire mesh laid on the slope to cover the entire slope with mortar. As a greening measure to preserve the natural environment of the slope, after laying a wire mesh on the slope, soil containing an anti-corrosive agent is sprayed on the ground including the wire mesh along with plant seeds. Each method uses a construction method that creates a layer of soil for vegetation on top. (Problem to be solved by the invention 1) The construction method of covering the entire slope with mortar satisfies the slope strength and prevents collapse, but the aesthetics are impaired and the surrounding natural environment is degraded. In addition, the construction method of creating a layer of soil on the slope can achieve the purpose of greening, but the strength of the slope is relatively weak, the soil base is missing, the geology is exposed, and the original ground is not restored. [Means for solving the problem] The present invention has been made in view of the point mentioned in 1.The purpose of the present invention is to provide greening on the slope covered with mortar. A large number of spaces are constructed in advance, and after the spraying of mortar is completed in the areas excluding these spaces, the spaces are filled with vegetation material to ensure the reinforcement of the slope and greening at the same time. It is therefore an object of the present invention to provide a method for greening a slope of a ground which is improved.The above object of the present invention is to lay a wire mesh on the slope of a ground, and to install a large number of wire mesh frames at intervals on the wire mesh. At the same time as installing, the legs of the wire mesh frame are supported on the ground slope -(-, and then mortar is sprayed onto the ground slope excluding the installation part of the mixed mesh frame.
A mortar layer is formed on the slope of the ground surrounding the wire mesh frame, and the space on the slope of the ground formed by each wire mesh frame is filled with vegetation material such as soil mixed with seeds. ,
This is achieved by a greening method for Shishida ground slopes that creates a green layer partially on the slopes of the ground. [Example] Below, the ground greening method according to the present invention will be explained with reference to the attached drawings. Using the anchors 2, first, a required gap is formed on the slope 1 of the ground and the wire mesh 3 is laid. Next, a large number of wire mesh frames 4 are attached to the wire mesh 3 at intervals by means such as tying. In this case, each wire mesh frame 4 is placed on the slope 1 of the ground 111.
A water collection pipe 5 is installed in advance in correspondence with the installation part, and this water collection pipe 5 is connected to a drain pipe 6. Also, wire mesh frame 4
is a large number of legs 4-a (vertical striations) extending downward from the lower periphery.
These legs 4a pass through the mesh of the wire mesh 3 to support the tips on the ground slope 1, and the wire mesh frame 4 is installed to determine the condition and at the same time to stabilize the wire mesh 3 that has been laid. ing. Next, each wire mesh frame 4 is temporarily covered with a covering material such as cardboard or kraft paper, and mortar is sprayed on the slope 1 of the ground excluding the installation area of these wire mesh frames 4 by a normal method. , a mortar layer 7 is formed on the slope 1F of the ground.
After this mortar layer 7 has dried, the covering material is removed from the wire mesh frame 4, and the ground slope 1 formed by each wire mesh frame 4 is removed.
Each space above is filled with vegetation material such as soil mixed with anti-corrosive material and plant seeds, and the wire mesh frame = 4
- The present invention is carried out by partially creating a large number of greening layers 8 on the ground slope 1 in the area where the greenery 4 is installed. The drain pipe 6 is connected to the water collection pipe 5 in advance so as to protrude from the mortar layer 7 when the mortar layer 7 is formed. Effects of the Invention) The present invention is as described above, and the wire mesh laid on the slope of the earth has a plurality of wire mesh frames connected at intervals on the wire mesh, and legs of the wire mesh frames. Because the mortar is supported on the slope of the ground, its laying condition is stable and problems such as bending are eliminated, and the mortar spraying work can be carried out reliably and with good appearance. Therefore, according to the present invention, a space for creating a greening layer can be provided in an orderly manner on the slope of the ground, and the size of the wire mesh frame or the number of wire mesh frames can be freely selected depending on the construction site. ,
It has the advantage of being able to carry out greening work rationally and economically, and in addition, the mortar layer satisfies the slope strength of the ground, making it possible to completely achieve greening while preventing collapse accidents. It is extremely useful as a greening method for reinforcing mountain slopes and preserving nature and the environment.
