DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embankment method for expanding a ground such as a road, a lands or a railway platform, and more particularly to a method of utilizing waste.

[0002]

2. Description of the Related Art With the development of a transportation network, ground expansion work is being performed in various places to increase the width of roads, and ground expansion work is increasing in order to expand land for public use or private land. are doing. In these expansion works,
Usually, a retaining wall is erected at the end of the ground to be expanded, and soil, sand or gravel is buried in the expanded portion between the original ground and the retaining wall to perform embankment. However, in this method,
Due to the large weight of the material, the earth pressure is increased, so that settlement is likely to occur or a slip phenomenon is likely to occur. In addition, it took time and effort to transport. Conventionally, therefore, there has been proposed a method for reducing the weight by forming a block of polystyrene foam by in-mold or extruding polystyrene using the material characteristics of polystyrene foam to form a block of polystyrene foam and embedding it as an embankment of expanded ground.

[0003]

However, in the method of burying a large number of blocks of styrofoam, the adhesion between the original ground and the ground is lowered, so that the slip phenomenon cannot be prevented or the original ground cannot be prevented. It is difficult to completely fill the gap between the extension and the gap between the blocks, and this gap reduces the strength. In addition, polystyrene blocks could easily cause fires, as they easily dissolved in gasoline and ignited. On the other hand, the amount of garbage discarded from businesses and households has been increasing more and more in recent years, and it has become more difficult to take measures against such waste.
Therefore, it has become necessary to carry out waste treatment in civil engineering work.

The present invention solves the above-mentioned problems, and provides an embankment construction method capable of improving the adhesion to the original ground, forming an embankment as an expanded ground having no gap, and utilizing waste. The purpose is to do.

[0005]

In order to solve the above-mentioned problems, an embankment method for expanding ground according to the present invention is performed by the following method. That is, the molten liquid waste flows into the expanded ground portion, and after the liquid waste is solidified to form an embankment layer, a pavement layer is formed above the embankment layer. is there.

Preferably, a reinforcing layer is formed at an intermediate portion of the embankment layer.

[0007] More preferably, a net-like sheet is provided at an intermediate portion of the embankment layer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In the present invention, wastes from homes or factories are effectively used without detrimental effects, and wastes such as plastics and nylons are melted and made into a liquid state. Civil engineering method, especially used as an embankment layer for expanded ground.

The embodiment shown in FIG. 1 shows a construction method of an extension ground for widening a mountain road. An extension ground 1 is formed along a sloping surface 2 of a mountain toward a valley side. 1, a retaining wall 3 erected at the side end, an embankment layer 4 formed between the inclined surface 2 and the retaining wall 3, a pavement foundation layer 6 laid on the upper surface of the embankment layer 4, and a pavement foundation layer 6 And a pavement layer 7 laid on the upper surface of the sheet.

In the construction method of the expanded ground 1, first, after cutting the vegetation on the inclined surface, the retaining wall 3 is erected at a predetermined position.
The retaining wall 3 is formed in a reinforced concrete shape in which a plurality of H-shaped steels erected in the vertical direction and one H-shaped steel laid horizontally are fixed with concrete around the lower part of the retaining wall 3. Is buried below the ground via mortar concrete.

When the retaining wall 3 is formed, the embankment layer 4 is then charged. The embankment layer 4 is entirely formed of the liquid waste layer 5 in the present embodiment, and forms the waste layer 5 by flowing molten liquid waste. Therefore, the liquid waste adheres to the original ground (mountain) 8 without any gap. When the waste layer 5 is solidified by natural cooling or air cooling, ready-mixed concrete flows into the upper surface to form a pavement base layer 6, and thereafter,
The pavement layer 7 is formed by asphalt in conformity with the upper surface of the original road.

When the width and length of the expanded ground 1 become large, a plurality of anchors 9 are driven toward the mountain 8 to firmly fix the expanded ground 1 to the mountain 8 so as to cope with an earthquake. If necessary, a drain pipe for draining water is buried by burying a vinyl chloride pipe (not shown).

FIG. 2 shows a construction method of the expanded ground 11 for reinforcing the embankment layer in order to increase the strength of the embankment layer. The embankment layer 12 formed between the slope 2 of the mountain and the retaining wall 3 includes: A base layer 13 laid with concrete is formed at a lower portion, and a liquid waste flows into the intermediate layer of the embankment layer 12 above the base layer 13 to form a waste layer 14. Further, the burned paper or wood ash is mixed with the cement and water above the mixture, and the mixed cement stirred therein flows to form the reinforcing layer 15, and the liquid waste flows above the waste material to form the reinforcing layer 15. The layer 14 is formed. Therefore, paper and wood ash contained in the reinforcing layer 15 are effectively used as waste. Then, a pavement base layer 6 and a pavement layer 7 are formed in the same manner as in the embodiment of FIG. 1, and an anchor 9 is cast from the outside of the retaining wall 3.

The reinforcing layer 15 flowing between the waste layers 14, 14 may be formed in a plurality of stages instead of a single stage. The base layer 13 formed below the embankment layer 12 may not be formed if necessary.

FIG. 3 shows a construction method of the expanded ground 21 for reinforcing as a measure against cracking of the waste layer. The embankment layer 22 is formed by a waste layer 23 and a plurality of wire meshes 24. The wire mesh 24 is fixedly arranged in a plurality of stages on the embankment layer 22 that is formed before the liquid waste flows in. Since the liquid waste passes through the mesh 24 of the wire mesh fixedly arranged, the embankment layer 22 can be formed without gaps.

In this embodiment, a reinforcing layer 15 made of mixed cement may be provided between the waste layers 23 described with reference to FIG. 2, and if necessary, an anchor 9 may be provided. Is also good.

As described above, the method of expanding the width of the mountain road is as follows:
By flowing the molten liquid waste, the waste can be effectively used. Liquid waste is formed by melting various kinds of waste from households or factories, such as plastic products and nylon products, or paper or wood ash, into a high-temperature liquid. The liquid waste is filled into a truck tank and transported to the site. After flowing into the embankment layer at the site, it is fixed by natural cooling or air cooling. For this reason, it is possible to form an expanded ground which has no gap and has good adhesion and can be constructed by an easy operation.

[0019] The above-mentioned construction method for embedding liquid waste in liquid form is not limited to roads, but also works for expanding the premises of public land and private land,
The present invention can be applied to construction for expanding a platform of a station, construction of a factory site, and the like.

FIG. 4 shows a construction method for expanding the site of a private land. The expanded ground 31 is obtained by digging up the expanded ground and then forming a plurality of commercially available blocks 33 at the peripheral end of the embankment layer 32. The pile is fixed on the steps, and then the liquid waste is introduced to form the embankment layer 32 as the waste layer 34. Then, a pavement layer 35 is formed by laying concrete, soil, or stone on the upper surface according to the original site.

FIG. 5 is a cross-sectional view of the platform of the station, showing a method of expanding the width of the platform 40. The expanded ground 41 of the platform 40 is
The frame 42 is formed by integrally fixing the side 2a and the side portion 42b with concrete, and the liquid waste flows into the frame 42 to form the embankment layer 43. Concrete as a pavement layer 44 is laid on the upper surface of the embankment layer 43 in accordance with the upper surface of the platform 40. In this case, an anchor may be cast from the outside of the frame 42 toward the platform 40.

[0022]

According to the present invention, in the method of embankment of the expanded ground, the molten liquid waste flows into the expanded ground portion, and the liquid waste is solidified to form an embankment layer. Form a paving layer above the layer. For this reason, a large amount of waste can be effectively used, and the liquid waste can flow into the original ground without any gap, thereby improving the adhesion.

In the method for embankment of the expanded ground, since the reinforcing layer is formed in the middle of the embankment layer, the strength of the embankment layer containing liquid waste can be improved.

Further, in the method of embankment of the expanded ground, since the mesh sheet is disposed in the middle portion of the embankment layer, it is possible to easily take measures against cracking of the embankment layer.
