2. Description of the Related Art As one of embankment methods, as shown in FIG. 6, a reinforcing net 2 (a grid-like or non-woven fabric made of a synthetic resin generally called geotextile) is formed on an upper surface on which an embankment layer 1a is formed. There is a construction method in which the embankment 1 having a predetermined height is formed by repeating the step of laying the member). In this embankment method, since the reinforcing net 2 serves as a resistor, the strength is higher than a simple embankment. In addition, as a method of processing the terminal of the reinforcing net 2, the sandbags 3 are piled up on the slope, and the terminals 2a of the reinforcing net 2 are passed through the surface of the sandbag 3.
It is wrapped around the back of the sandbag 3 and restrained.

[0003]

However, this sandbag entrapment method has various problems that the workability is poor, the stability is poor, and the aesthetic appearance is not preferable. Therefore, a method of laying a sill on the slope has been proposed as an alternative to the sandbag 3, but in this method, the opening inside the sill has no binding force against earth pressure, and there is a risk that sediment may flow out. There was a point.

The present invention has been made in view of the above-mentioned problem, and the construction on the slope is easy and reliable. The outflow of the earth and sand is prevented by giving the opening inside the law frame a binding force against the earth pressure in advance. It is an object of the present invention to provide a legal frame unit in an embankment method that can prevent the occurrence of the problem.

[0005]

In order to achieve the above-mentioned object, the legal frame unit according to the present invention alternately repeats a step of laying an embankment layer and a step of laying a reinforcing net on an upper surface of the embankment layer. In the embankment method of covering the slope by laying a slope unit on the slope of the fill while embedding the embankment of a predetermined height, the slope unit is a frame-shaped slope frame body, and a frame of the slope frame body. The legal frame to cover the inner opening
And a retaining member fixed to the back side of the main body .

It is preferable that the law frame unit has a pair of support members provided on the back of the law frame body to support the law frame body.

Further, it is preferable that the retaining member is made of a mesh member stretched over the opening of the frame body so as to cover the opening in the frame, and a cloth material fixed on the mesh member.

Alternatively, it is preferable that the retaining member is a plate-like member fixed to cover the opening in the frame of the legal frame main body.

[0009]

According to the present invention having the above construction, the earth pressure applied to the slope is restrained by the law frame body constituting the law frame unit and the retaining member provided in the opening inside the law frame body. You.

In addition, the slope angle of the slope can be set according to the angle formed between the legal frame main body and the support member fixed thereto, and the reinforcing net is clamped between legal frame units disposed above and below the reinforcing net. Terminal processing.

Further, when a combination of a net-like member and a cloth material is used as the retaining member, the outflow of earth and sand can be prevented, and vegetation can be vegetated in the inside opening of the legal frame main body to be green.

In addition, when a plate-like member is used as the retaining member, the outflow of earth and sand can be prevented, and by making the surface a decorative plate, an artificial aesthetic appearance such as color and pattern can be created.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. 1 and 2 show a first embodiment of the present invention. The same parts as those in the conventional example will be described with the same reference numerals. The legal frame unit 10 is formed in advance by factory production or the like, and includes a rectangular legal frame main body 12 and a pair of support bars 14 which are support members hinged to bottoms on both sides on the rear side of the legal frame main body 12.
An adjusting bar 16 suspended between the support bar 14 and the legal frame main body 12; a tension bar that is stretched inside the rear surface of the legal frame main body 12, and whose peripheral edge is fixed to the legal frame main body 12 via a plurality of bolts 18. A high-strength net 20 which is a mesh member such as expanded metal having a relatively large mesh;
Non-woven fabric 22 as a cloth material arranged on the back of
It consists of The legal frame main body 12 is formed of a lightweight material such as metal, plastic, fiber reinforced concrete and the like. A bolt insertion hole 23 is formed in each side 12 a of the legal frame main body 12, and a connecting bolt 24 is inserted into the bolt insertion hole 23 in a state where each legal frame unit 10 is laid on the side of the slope. By fastening the protruding end with a nut (not shown), the units 10 can be integrally connected vertically and horizontally.

In the embankment method using the above-mentioned method frame unit 10, the height pitch of the embankment layer 1a and the laying pitch of the method frame unit 10 are set to be the same. First, as shown in FIG. With the slope angle of the slope frame body 12 determined by 16 and the slope of the slope face set, the slope frame units 10 are arranged in a line at the bottom of the position to be the slope face.

Next, as shown in FIG.
a is raised to the upper edge of the legal frame main body 12 disposed at the lowermost layer, and after leveling, the reinforcing net 2 is laid on the upper surface of the embankment layer 1a, and the terminal 2a is put on the upper surface of the legal frame main body 10.

Next, as shown in FIG. 1C, the second-stage legal frame unit 10 is installed above the first-stage legal frame unit 10 and bolts are tightened between them.
2 is clamped between the upper and lower legal frame units 10, and bolts 24
The terminal is constrained in accordance with the tightening pressure by cutting off the protruding end after all the work is completed. In addition, by combining the slope frame unit 10 and the reinforcing net 12 in this way, the stability of the slope can be enhanced, and the construction can be performed even on a steep slope which was difficult in the past.

The same operation as described above is performed in the second stage, and when this operation is repeated up to the predetermined number of stages, the embankment 1 is completed as shown in FIG.

The earth pressure applied to the slope in the completed state is mainly supported by the high-strength net 20. Since the high strength net 20 is made of a large mesh for weight reduction, the nonwoven fabric 22 on the back side also supports the earth pressure applied between the meshes and also prevents the outflow of earth and sand. Since this nonwoven fabric 22 is rich in water permeability and air permeability, it can be sowed and greened by vegetation, whereby the artificial structure is concealed and the aesthetic appearance can be enhanced. Note that a woven fabric may be used instead of the nonwoven fabric 22.

FIGS. 4 and 5 show a second embodiment of the present invention. In the figure, a plate 30 is fixedly provided as a plate-like retaining member on the back surface of the legal frame main body 12. The plate 30 may be made of any material as long as the required strength and durability are secured. The plate 30 may be formed integrally with the legal frame main body 12 or may be formed by means of bolts and nuts. It is fixed to. In this embodiment, the embankment construction method is the same as that of the above embodiment. In the construction completed state, instead of the combination of the high-strength net 20 and the nonwoven fabric 22 of the embodiment, the plate 30 opposes the earth pressure applied to the slope. In this embodiment, a decorative panel having a color, a pattern, or the like on the surface of the plate 30 may be used. In this case, an aesthetic appearance of the artificially formed object can be provided.

[0020]

[Effect of the Invention] As described in detail in the above embodiments, in the method frame unit in the embankment method according to the present invention, the earth pressure applied to the slope is provided in the opening inside the body of the method frame. The slope angle of the slope can be set in accordance with the angle of each law frame unit set by the support member while being restrained by the retaining member.

Further, since the reinforcing net is processed by being clamped between the upper and lower legal frame units, the reinforcing net is reinforced in comparison with the conventional method in which the slope is reinforced using sandbags and the reinforcing net is processed. The construction is simple and reliable, and the stability of the slope is increased, so that the construction can be performed even on a steep slope, and the appearance in a finished state is improved.

In particular, when a combination of a mesh member and a cloth material is used as the retaining member, the inside of the legal frame body can be greened,
In addition, when a plate-shaped member is used as the retaining member, there is an advantage that, by using a decorative panel on the surface thereof, an artificial aesthetic appearance such as a color or a pattern can be created, and aesthetic considerations can be made.
