Description

[Detailed Description of the Invention] The present invention relates to a block (hereinafter referred to as a construction block) as a construction product for road retaining works, earth retaining works, river revetment work, residential land preparation work, etc.

In conventional civil engineering work, concrete block laying or concrete retaining wall work is constructed for road retaining works, earth retaining works, river revetment work, residential land preparation work, etc. It was difficult to pour concrete with the same high density as the main body. This is because it is difficult to fix the back formwork of the concrete, and even if it is suppressed by backfilling stone, the back form will move when the concrete is being compacted by vibration with a vibrator, and the density will be lowered. This is because high concrete cannot be placed. (For this reason, the actual situation is that the inappropriateness of concrete is often pointed out during completion inspections and accounting audits of construction work.) In this way, it is difficult to make concrete to the specified thickness and cleanly. (No soil, sand, etc. mixed in)
In order to enable high-density concrete to be cast, the inventor of this invention had already filed a utility model registration application in 1988.
67976, and the present invention is a further improvement.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
