BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete sink in which a column material and a square material are formed of concrete.

[0002]

2. Description of the Related Art Recently, as a flood control method for preventing floods, there has been a request to consider the preservation of the living environment of people, and among them, there is a need to regenerate a natural river so as to be suitable for the inhabitation of living organisms newly gathering on the waterside. For example, there is a demand for the creation of multi-natural rivers with diverse environmental conditions. Conventionally, as a river construction method satisfying such a requirement of a multi-natural type, a construction method such as a futon basket work, a cobblestone revetment work, a gabion work, a woodwork sink, a vegetation work, and the like are conventionally performed. Of these, the woodwork sinking method is a particularly traditional river construction method, which has the effect of preventing scouring of chestnut stones that are packed in a frame of several steps assembled in a roughly cross-girder plane, and can provide a hiding place for fish and small animals It has been widely used as a river construction method because it has the advantage of ensuring the preservation of ecosystems. In this woodwork sinking method, a large number of support members and square materials are formed by cutting logs having substantially the same cross-sectional area into a specified length. Then, the frame is formed by assembling a desired number of steps in such a manner that the square material is substantially opposed to the pillar material arranged substantially diagonally in the front-rear direction and the left-right direction in a plane substantially in a cross shape. Thereafter, the chestnut stone was buried in the frame and submerged at a predetermined location in the river.

[0003]

However, in recent years, it is difficult to prepare a large number of logs of the same thickness (cross-sectional area) at the same time in the above-mentioned wood sinking method. Deforestation in an attempt to obtain it has been a problem from the standpoint of forest conservation. In addition, when logs are used as square materials or struts, the logs were cut to the specified length at the construction site, and then bolt holes for inserting bolts for connection were provided in the struts and square materials. It takes a lot of time and effort to process the components such as steel and support materials, and the work efficiency in the construction is poor. Moreover, when wooden pillars and square materials are used, they have low specific gravity and are easily washed away by receiving water pressure. Therefore, it is indispensable to drive the pillars into the riverbed to prevent this. Therefore, it was difficult to fix the pillar material in a river with pumice in the riverbed, making it difficult to work. Furthermore, wooden squares and struts such as logs decayed, so their service life was short, repairs after construction were frequent, and they were not suitable for storage.

[0004] Accordingly, the present invention provides a method that does not impair the environment.
Moreover rectangular rated material and struts like components to substantially the same length without requiring post-processing of any of substantially the same cross-sectional area, the quality components can be easily obtained, and the phase to the water flow of the river in the enforcement field
In response, it is easy to assemble with sufficient planar spread and sufficient height , greatly improving work efficiency, and furthermore, robust structure
The specific gravity is large and the water is reliably fixed to the river
An object of the present invention is to make it difficult to flow even under pressure, to have no decay, to have a long service life, and to suitably repair and store components.
