Abstract

PURPOSE:To effectively utilize the ground by erecting a pair of wall-like concrete layers, filling a banking material inside, and penetrating, fixing, and reinforcing the concrete layers with multiple solid rods made of fiber-reinforced resin. CONSTITUTION:A pair of vertical concrete layers 7 are erected at positions corresponding to bank side faces. The concrete layers 7 are penetrated, fitted, and fixed with multiple solid bar-like rods 9 made of high-elasticity carbon fiber-reinforced resin. A banking material mixed with cement and lime is filled and tightened between the concrete layers 7 to form a bank 5. A roadbed 4 made of slag and crushed stones is provided on the bank 5. Ballast 3, crossties 2, and rails 1 are provided on the roadbed 4 for a track, and pavement with asphalt or concrete is formed on the roadbed 4 for a road. The ground can be effectively utilized while the face of slope is omitted, and dynamic and static high loads can be supported over a long period.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of embankment for orbital embankments, road embankments, etc., and more particularly to a method of embankment that can withstand a high load for a long period of time while omitting a sloped surface.

[0002]

2. Description of the Related Art Conventionally, on railroad tracks or the like, as shown in FIG. 1, a sleeper 2 is provided below a rail 1 and a ballast 3 is further laid. .
This roadbed 3 is an aggregate of granular materials such as crushed stones, which supports the sleeper at a predetermined position, disperses and transmits the dynamic and static loads of the wheels and the like acting on the sleeper, and further secures the riding comfort and the vibration noise. Relaxation,
It is intended to suppress miscellaneous growth.

In recent years, the proportion of concrete viaducts has increased in the Shinkansen and urban areas, but in conventional lines, considering economic efficiency, and improving and disaster recovery, Fig. 1 As shown, a roadbed (embankment surface layer portion) 4 that directly supports the track is provided in the lower part of the track, and an embankment 5 is overwhelmingly below the roadbed. Then, the side surfaces of the roadbed 4 and the embankment 5 are sloped surfaces 6
It is called, and the slope that is artificially made with a constant slope spreads out toward the bottom. In the past, it was sometimes called roadbed including the embankment, but at present, the roadbed and the embankment (some are also called roadbed) are clearly distinguished, and the roadbed refers to the number of surface layers of 10 cm. It was Therefore, for convenience of explanation, the roadbed will be grasped as the embankment surface layer and included in the embankment.

In such a conventional embankment method,
Since the slope 6 is provided, there is a problem that a lot of land is required. This problem is particularly noticeable in urban areas where land is scarce. In addition, there is a problem of collapse of the sloped surface 6 such that the sloped surface 6 is eroded or flows out, and therefore it is necessary to repair it regularly. In this example, the embankment for the track is taken as an example, but the same applies to the embankment for the road such as a highway.

As one means for solving such a problem, an embankment as shown in FIG. 2 has been proposed. In the figure, the same reference numerals as those in FIG. 1 denote the same parts, 7 is a vertical concrete layer, and 8 is a reinforcing bolt.

As shown in FIG. 2, all the sloping surfaces are cut out and, instead, a vertical concrete layer 7 is provided on the side surfaces. Further, the embankment 5 has a sturdy structure by compressing and stacking the earth and sand reinforced by a special net or sandbag one by one. Further, a plurality of reinforcing bolts 8 are driven into the embankment 5 and are solidified and reinforced by a coagulant. With this method, in the case of a single line, the site will be 1/4 of the conventional one, and the remaining site will be available for parking lots.

However, also in this case, there is a problem in strength of the embankment, and there is a problem that it cannot withstand a long-term dynamic or static load.

[0008]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an embankment method capable of effectively utilizing land and capable of withstanding a high load for a long period of time. .

[0009]

The above-mentioned object of the present invention is solved by penetrating a plurality of solid rod-shaped rods made of fiber reinforced resin on the side surface of the embankment and reinforcing the same.

That is, the embankment method of the present invention is characterized in that the side surface is held by the concrete layer and a plurality of solid rod-shaped rods made of fiber reinforced resin are pierced through the side surface for reinforcement.

[0011]

In the present invention, since a plurality of solid rod-shaped rods made of fiber reinforced resin are penetrated on the side surface of the embankment, there is no corrosion and, because of high elasticity, no displacement occurs. Moreover, since a long rod can be used by the pull-through method, a simple construction method can be adopted. Therefore, it is possible to withstand a high load for a long period of time.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

EXAMPLE FIG. 3 is a schematic cross-sectional view of an embankment for raceways according to the present invention. In FIG. 3, the same reference numerals as those in FIG. 2 indicate the same things, 9 is a solid rod rod made of fiber reinforced resin, Denoted at 10 are fixing means, respectively.

First, a vertical concrete layer 7 is provided at a position corresponding to the side surface of the embankment. Next, the embankment material is laminated inside. This embankment material is not particularly limited, and a general material is used. As such an embankment material, a material which has been subjected to a stable treatment such as cement mixing, lime mixing, and mixing (mixing quality) may be used. Then, these embankment materials are compacted to form the embankment 5. Further, as described above, the earth and sand reinforced by the special net or sandbag may be compressed step by step to form the embankment 5.

Next, the roadbed 4 as the surface layer of the embankment is provided on the embankment 5. The roadbed 4 may be a conventionally known soil roadbed or a reinforced slag roadbed or a crushed stone roadbed.

In the present invention, a plurality of solid rod-shaped rods 9 made of fiber reinforced resin are pierced and reinforced on the side surface of such an embankment for raceways. As the solid rod-shaped rod used here, one made of a highly elastic carbon fiber reinforced resin is particularly preferably used. It is also preferable that the rod is a pultrusion rod. If such a solid rod-shaped rod is used, the embankment can be pierced and reinforced by a simple construction method. The fixing means 10 for the solid rod 9 is not particularly limited, and bolts / nuts, conical self-clamping jigs, etc. may be used.

In this way, the embankment for tracks of the present invention is obtained. Then, the roadbed 3 is provided on the roadbed 4, and the sleepers 2 and further the rails 1 are respectively installed thereon.

In the case of road embankments, asphalt pavement, concrete pavement, etc. are made after the roadbed is reinforced.

[0019]

According to the embankment method of the present invention as described above, the land can be effectively used, and moreover, it can be used for a long period of time.
Can withstand high static loads.
