Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lightweight embankment structure used when constructing structures such as roads, tracks and buildings on soft ground.

[0002]

2. Description of the Related Art Conventionally, as a lightweight embankment structure of this type, for example, as disclosed in Japanese Patent Publication No. 3-4693, in a light embankment constructed by stacking hard foam plastic blocks, hard foam plastics vertically adjacent to each other. It is known that a connecting tool having vertically protruding teeth is interposed between blocks and the teeth of the connecting tool are pierced into the upper and lower hard foam plastic blocks to connect the blocks to each other. According to this lightweight embankment structure, since the blocks are vertically connected, it is difficult for the blocks to be displaced even by a lateral force, and durability against an earthquake is improved.

[0003]

However, in the above conventional structure, since the teeth on both sides of the connector are pierced into the upper and lower blocks, the teeth of the connector are pierced into the lower block during construction and the upper block is pierced. At the stage of carrying in, the teeth of the connecting tool are raised above the lower block,
Very dangerous for workers.

Further, since only the teeth are pierced in the block, when the vibration is applied, the holes formed by the teeth being pierced gradually widen and the biting of the teeth into the block is loosened, resulting in a lightweight embankment structure. There is also a drawback that the strength of the is reduced.

The present invention has been made paying attention to such a point, and an object thereof is to simply and safely connect the blocks by the adhesive force of a member arranged between the blocks. It is to be able to construct a lightweight embankment structure, to resist external forces such as vibration, and to absorb the load to some extent.

[0006]

In order to achieve the above object, the lightweight embankment structure of claim 1 is premised on a lightweight embankment structure constructed by stacking blocks made of foamed resin, and adjacent blocks to this are It is configured to be connected to a part of each block by a reinforcing body that is adhered via an adhesive portion.

According to a second aspect of the present invention, in the light-weight embankment structure according to the above structure, the reinforcing body is a double-sided adhesive reinforcing body which is a foil body having adhesive portions formed on both sides and a foil body having an adhesive portion formed on one surface. There is a certain one-sided adhesive reinforcing body, and these are used properly according to the site.

[0008]

In the lightweight embankment structure of the first aspect, since there is only the reinforcing body having an adhesive portion other than the block, no dangerous places such as protrusions are formed. Further, since the block connecting strength is increased by the adhesive force of the adhesive portion, the block connecting is not loosened even when an external force such as vibration is applied in an arbitrary direction. Moreover, since the reinforcing body only adheres to a part of the blocks and the blocks are not solidly attached, even if the lightweight embankment structure is deformed under load, this deformation is allowed to some extent and excessive stress does not occur. .

In the lightweight embankment structure according to the second aspect of the present invention, for the double-sided adhesive reinforcement, for example, the reinforcement is bonded to an existing block,
The blocks are connected by a method of adhering the next block on the reinforcing body. For single-sided adhesive reinforcement,
For example, blocks are arranged by arranging a plurality of blocks and bonding a series of reinforcing bodies to the blocks.
