DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a method for greening slopes such as roads and lands, and a gauge formwork used for the method.

[0002]

2. Description of the Related Art Generally, when greening a slope, a grid-like slope is formed on the slope, and a vegetation material containing various seeds and fertilizers is sprayed into the slope. Arranging a vegetation bag loaded with the vegetation material, and protecting the vegetation material with the law frame without causing run-off of the vegetation material; They are germinated and raised within.

The applicant of the present application has proposed a method described in Japanese Patent Publication No. 4-53212 as a method of forming a frame. The content of the proposal is to use a simple gutter-shaped formwork consisting of a plurality of horizontal wires and vertical wires, install a plurality of the forms in a grid on the slope, and add mortar or concrete to each of these forms. Is sprayed to form the legal frame.

[0004]

However, according to the above-mentioned method using the simple formwork, the construction along the unevenness of the slope can be performed without the need for a separate leveling operation of the slope. In addition, since the lawn frame is integrally and firmly connected to the slope, the runoff of the vegetation material located in the lawn frame can be reliably prevented, and the vegetation can be prevented. While various seeds in the material can be satisfactorily grown in the method frame and the erosion and weathering of the slope can be suppressed by the method frame, there are the following problems.

That is, since the mortar or concrete is sprayed as an on-site work at an unstable place on the slope, the sprayed thickness of the mortar or the like with respect to the simplified form is likely to be non-uniform. Since it is also difficult to accurately check the sprayed thickness of mortar or the like, a legal frame having a predetermined strength cannot be accurately formed. In particular, the mortar or the like is sprayed on the mold so as to have a cross-sectional shape.
For example, since the drainage of the method frame against rainwater and the like becomes good, it is possible to suppress the erosion and weathering of the method frame due to the rainwater and the like, but as described above, the mortar and the like are formed to have a sectional shape. In particular, when spraying onto the gutter-shaped formwork, the sprayed thickness of the mortar or the like tends to be non-uniform, and it is difficult to obtain a legal frame having a predetermined strength.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a method of forming a cross section having a good drainage property by spraying mortar or concrete onto a slope. However, it is an object of the present invention to provide a method for constructing a method frame capable of reliably forming a method frame having a predetermined strength by making the sprayed thickness of the mortar or the like uniform and a gauge mold used for the method.

[0007]

According to a first aspect of the present invention, there is provided a method for forming a frame by spraying concrete or mortar on a slope, the method comprising: And a vertical line erected at an intermediate portion in the longitudinal direction of the ceiling line, and the upper end of the vertical line and both ends in the longitudinal direction of the ceiling line are located on the cross-sectional outer peripheral line of the legal frame to be formed. Forming a gauge formwork arranged on the slope, installing the gauge formwork on the slope, while using the upper end of the vertical line and both ends in the length direction of the ceiling line in the gauge form as a guide. Concrete and mortar were sprayed to form a legal framework.

According to a second aspect of the present invention, there is provided a gauge formwork comprising at least a ceiling line and a vertical line erected at an intermediate portion in the longitudinal direction of the ceiling line, and an upper end of the vertical line. And both ends of the ceiling line in the longitudinal direction are formed on the cross-sectional outer peripheral line of the legal frame to be formed.

[0009]

When a slope is formed on a slope according to the first aspect of the present invention, first, a plurality of the gauge forms are installed on the slope, and upper end portions of the vertical lines in these gauge forms are formed. And the longitudinal ends of the ceiling line as a guide,
Concrete or mortar is sprayed on the slope. By doing so, the mortar or the like can be sprayed accurately to the slope with a predetermined thickness, and a legal frame having a predetermined strength can be reliably formed. It is mandatory to make the thickness of the steel (this is called fog thickness) constant (at least 5 cm from any surface of the rebar according to the current civil engineering standards) as a quality control standard to obtain a grid frame of the required strength. However, the gauge form also has the function of keeping the fog thickness constant.

In the method of the first aspect of the present invention, even when the mortar or the like is sprayed on the slope in such a manner as to have a cross-section, the above-mentioned parts of the gauge mold are sprayed as a guide. Thereby, since it can be sprayed accurately to a predetermined thickness, while maintaining the predetermined strength in the law frame, the law frame is formed into a cross-sectional shape, the drainage of the rain water and the like is improved, and the rain water is used. Erosion and weathering of the frame can be suppressed, and root rot of plants grown in the frame can be effectively prevented. Moreover, in the above-mentioned slope construction method, the mortar or the like is directly sprayed on the slope using the gauge formwork, thereby eliminating the need for a separate leveling operation of the slope as described above. Construction can be easily performed along the irregularities of the vegetation material, and since the lawn is firmly and integrally connected to the slope, the vegetation material located in the lawn can be surely prevented from flowing out. By inhibiting the growth, various seeds in the vegetation material can be satisfactorily grown in the method frame.

Further, a gauge formwork according to a second aspect of the present invention includes at least a ceiling line and a vertical line erected at an intermediate portion in the longitudinal direction of the ceiling line, and an upper end portion of the vertical line. And both ends in the length direction of the ceiling line are arranged and formed on the cross-sectional outer peripheral line of the legal frame to be formed, so that by using the legal frame method, various advantages as described above can be obtained. While being able to demonstrate, the manufacturing cost can be reduced by simplifying the entire configuration of the gauge formwork.
