Abstract

PURPOSE:To enhance the strength of an embankment by burying a plate like concrete block as core material in the embankment. CONSTITUTION:In embankntent reinforcing structure, a ditch 2 is provided at the center of an embankment 1, and a plate like concrete block 3 is buried in the ditch 2. As to the concrete block 3, the concrete block 3 previously formed into plate shape is fitted and buried in the ditch 2 formed in the embankment 1, or concrete material (ready-mixed concrete) may be filled in the ditch 2 and hardened to form a plate like concrete block 3'. The strength of the embankment can be thereby enhanced by the concrete block 3 or 3' serving as the core.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for increasing the strength of a bank.

[0002]

2. Description of the Related Art Conventionally, embankments have been gradually piled up while strengthening stones and soil to increase their strength. However, there is a limit in strength only due to pressure, and the width of the levee had to be increased.

[0003]

The present invention was devised in view of the above circumstances, and its main problem is to
The purpose of the present invention is to provide a levee reinforcement structure by embedding a plate-shaped concrete block as a core material in the levee to enhance the strength.

[0004]

In order to solve the above problems, according to the invention of claim 1, (a). A plate-like concrete block extending in the length direction is embedded in a middle portion in the width direction of the embankment. We are taking technical measures to do so. Also,
In the invention of claim 2, (b). A plurality of concrete blocks are connected in a straight line, and separate concrete blocks are arranged in parallel so as to cover the joints in front of or behind the joints. The technical means of becoming. According to the third aspect of the invention, the technical means is taken as (c). The waste is built in as the core material of the concrete block. In the invention of claim 4,
(d). A technical measure is taken such that a groove is formed at an intermediate position in the width direction of the embankment, and the groove is filled with concrete to form a plate-shaped concrete block.

[0005]

According to the present invention, the embankment is provided at a midway point,
Since the plate-shaped concrete block is buried as a wall, this serves as a core material to enhance the strength of the embankment. Further, when a plurality of concrete blocks are arranged in a straight line and used, another reinforcing concrete block that overlaps the front and rear at the joint portion is used, so that the strength at the joint can be increased. Further, this concrete block can also incorporate wastes or the like as its own core material. This concrete block has a structure in which a plate-shaped concrete block is inserted and embedded in a groove formed in a bank, or a concrete material is filled in the groove and hardened to form a plate-shaped concrete block. It may be.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the embankment reinforcing structure of the present invention will be described below with reference to the drawings. In the levee reinforcement structure shown in FIG. 1, a groove 2 is provided in the center of the levee 1, and a plate-shaped concrete block 3 is embedded in the groove 2. In this concrete block 3, a concrete block 3 formed in a plate shape in advance is fitted and embedded in a groove 2 formed in a bank. In the present invention, the groove 2 may be filled with concrete material (fresh concrete) and cured to form a plate-shaped concrete block 3'instead of the above configuration. In this case, a bag 4 made of a known mesh is laid in the groove 2 and the concrete material is filled therein.

The concrete block 3 buried in the embankment 1 is arranged so as to extend in the extension (length) direction of the embankment at the approximate center in the width direction of the embankment 1. When burying the concrete plate, the concrete blocks 3 cannot be formed in a series in the extending direction of the embankment 1.
Continuation of a plurality of concrete blocks 3 in the extension direction,
Connect them so that they are on the same straight line.

In this case, a joint 31 is formed between the concrete blocks 3, 3 which are connected to each other, so that the portion cannot be reinforced. Therefore, a separate auxiliary concrete block 6 is arranged in parallel so as to cover the joint 31 in front of or behind the joint 31 (see FIG. 3). As a result, since the joint 31 portion is reinforced by the auxiliary concrete block 6, the concrete block does not have to be integrally molded in a series. In addition, when the concrete material is filled as described above, it is possible to form a series without forming a seam, and it is possible to form a plate-shaped concrete block such as a curved surface or a bent surface, not limited to a straight line.

Further, in the above-mentioned embodiment, an example in which one concrete block 6 is embedded in the bank 1 has been shown.
It can be embedded at a midway point with a gap between them in the width direction (see FIG. 2). In this case, the strength of the embankment 1 can be further increased by the concrete blocks 6 which are spaced apart in the front-rear direction and arranged in parallel.

Further, this concrete block may contain waste as a core material of itself. For example, it is also possible to use a casing made of a rigid material, in which waste (as-is or after incineration, etc.) is contained and sealed to form a concrete block using the stored casing as a core material. Good.

[0011]

According to the present invention, since the plate-shaped concrete block is embedded at a midway position in the width direction of the embankment, the embankment can be thickened because the wall can be subjected to the load applied to the embankment. The strength can be increased without having to do so.
