 As one of the embankment methods, conventionally, as shown in FIG. 6, a reinforcing net 2 (a synthetic resin grid-like or non-woven fabric-like reinforcing member generally called geotextile) is laid on the upper surface where the embankment layer 1a is formed. There is a construction method in which the embankment 1 having a predetermined height is formed by repeating the above steps. In this embankment method, since the reinforcing net 2 serves as a resistor, the strength is higher than that of simple embankment. In addition, as a method of treating the end of the reinforcing net 2, the sandbag 3 is stacked on the slope and the end 2a of the reinforcing net 2 is wound around the back of the sandbag 3 to be restrained.

[0003]

[Problems to be solved by the device]

 However, this sandbag winding method has various problems in that it is poor in workability, lacks in stability, and is aesthetically unfavorable. Therefore, as an alternative to the sandbag 3, a method of laying a legal frame on the slope has been proposed. However, in this method, the opening inside the legal frame has no binding force against earth pressure, so there is a risk of sediment outflow. There was a point.

The present invention has been made in view of the above problems, and the construction on the slope is simple and reliable, and the opening inside the slope is provided with a binding force against earth pressure in advance, so It is an object of the present invention to provide a legal framework unit for the embankment method that can prevent runoff.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the method frame unit according to the present invention constructs an embankment with a predetermined height by alternately repeating the process of raising the embankment layer and the process of laying a reinforcing net on the upper surface of the embankment layer. In addition, in the embankment method of covering the slope by laying a slope frame unit on the slope of the embankment, the slope frame unit covers the slope-shaped slope frame main body and the opening in the frame of the slope frame main body. It is characterized by consisting of a fixed retaining member.

Further, it is preferable that the law frame unit has a pair of support members provided on a back portion of the law frame body and supporting the law frame body.

Further, it is preferable that the soil retaining member is composed of a mesh member stretched over the opening in the frame of the law frame body and a cloth material fixed to the mesh member.

Alternatively, the earth retaining member is preferably a plate-like member fixed to the opening in the frame of the law frame main body so as to cover the opening.

[0009]

[Action]

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

In addition, the inclination angle of the slope can be set according to the angle formed by the law frame main body and the support member fixed thereto, and the reinforcing net is held between the law frame units arranged above and below it. The terminal is processed by

Furthermore, when a combination of a net-like member and a cloth material is used as the soil retaining member, it is possible to prevent the outflow of earth and sand and to vegetate the inside opening of the legal frame body to be green.

【Example】

 Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2 show a first embodiment of the present invention. The same parts as those of the conventional example will be described with the same reference numerals. The law frame unit 10 is formed in advance by factory production or the like, and has a rectangular law frame main body 12 and a pair of support bars 14 that are hinge-supported support members on the bottoms on both sides of the back surface of the law frame main body 12. An adjusting bar 16 suspended between the support bar 14 and the law frame body 12, and a tension bar that is stretched on the inside of the back surface of the law frame body 12 and has its peripheral edge fixed to the law frame 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, and a cloth material which is arranged on the back surface of the net 20 and whose peripheral edge is fastened together to the method frame main body 12 by the bolt 18. Non-woven fabric 22 of. The method frame body 12 is made of a lightweight material such as metal, plastic, or fiber reinforced concrete. A bolt insertion hole 23 is formed on each side 12a of the law frame main body 12, and a connecting bolt 24 is inserted into the bolt insertion hole 23 with each law frame unit 10 spread on the slope. By tightening the protruding end with a nut (not shown), the units 10 can be integrally connected vertically and horizontally.

In the embankment method using the method frame unit 10 described above, the height pitch of the embankment layer 1a and the laying pitch of the method frame unit 10 are the same, and first, as shown in FIG. With the bar 16 defining the inclination angle of the main frame 12 and setting the slope of the slope, the normal frame units 10 are arranged in a line at the bottom of the position to be the slope.

Next, as shown in FIG. 2B, the embankment layer 1a is piled up to the upper edge of the law frame main body 12 arranged in the lowermost layer, and after laying the reinforcement net 2 the reinforcement net 2 is placed on the upper surface of the embankment layer 1a. And the terminal 2a is covered on the upper surface of the method frame body 10.

Next, as shown in FIG. 1C, the second-stage method frame unit 10 is installed on top of the first-step method frame unit 10 and bolted between the two, whereby the reinforcing net 12 Is clamped between the upper and lower legal frame units 10 and restrained according to the tightening pressure of the bolts 24, and the end portion protruding after all the construction work is cut off to be processed. Further, by combining the slope frame unit 10 and the reinforcing net 12 in this way, the stability of the slope can be enhanced, and it is possible to perform construction on a steep slope which was difficult in the past.

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

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 has a large mesh for weight reduction, the non-woven fabric 22 on the back side also supports the earth pressure applied between the meshes and at the same time prevents the outflow of sediment. Since the non-woven fabric 22 is highly water-permeable and breathable, it can be planted and vegetated so that it can be greened, which conceals the artificial structure and enhances its aesthetic appearance. A woven fabric may be used instead of the non-woven fabric 22.

4 and 5 show a second embodiment of the present invention. In the figure, a plate 30 is fixedly installed as a plate-shaped earth retaining member on the back surface of the method frame body 12. The plate 30 may be made of any material as long as the required strength and durability are secured, and it is formed integrally with the method frame body 12 or by means of screwing means such as bolts and nuts. And is fixed to the legal frame body 12. In this embodiment as well, the embankment construction method is the same as in the previous embodiment. In the construction completed state, the plate 30 counters the earth pressure applied to the slope instead of the combination of the high-strength net 20 and the non-woven fabric 22 of the embodiment. In this embodiment, the surface of the plate 30 may be a decorative panel having a color or a pattern. By doing so, it is possible to bring about an aesthetic effect of the artificially shaped object.

[0020]

[Effect of the device]

 As described above in detail with reference to each embodiment, in the case frame unit in the embankment method according to the present invention, the earth pressure applied to the slope is the earth retaining member provided in the opening inside the case body. The slope angle of the slope can be set according to the angle of each slope frame unit constrained by the support member and set by the support member.

Further, since the reinforcing net is subjected to the terminal treatment by being sandwiched between the upper and lower slope frame units, as compared with the conventional method in which the slope is reinforced by using sandbags and the terminal treatment of the reinforcing net is performed. The construction is simple and reliable, and the stability of the slope is improved, making it possible to construct even steep slopes and improving the appearance in the finished state.

In particular, when the combination of the mesh member and the cloth material is used as the soil retaining member, the inside of the method frame main body can be greened, and when the plate member is used as the soil retaining member, its surface is used as a cosmetic panel. By doing so, it is possible to create artificial aesthetics such as colors and patterns, and there are advantages such as aesthetic considerations.
