Retaining Wall Block Manufacturing Method and Retaining Wall Block Manufacturing Method {Manufacturing Method for a Block and Mold for the Block}

The present invention relates to a method for manufacturing a retaining wall block and a mold for manufacturing a retaining wall block.

Retaining wall blocks are constructed along slopes or bottom surfaces to prevent soil or wall breakdown, and are applied in all directions or in various civil works.

Since the retaining wall block manufactured for this purpose must cover a relatively wide slope or bottom surface, a sufficient amount of retaining wall block must be produced accordingly. Of course, the contractor should consider the economics, the retaining wall block will have to be manufactured in a mass production design.

However, the mass production method has the advantage of lowering the production cost, but all the retaining wall blocks produced have the same design, and the inclined surface or the bottom surface constructed by such retaining wall blocks does not fit with the surrounding natural environment due to the simple repeating appearance. I couldn't. That is, there is a problem that the uniform image of the artificial structure is strongly displayed by the simple repeating retaining wall block, which damages the surrounding natural environment.

In order to solve these problems, conventionally, the front of the retaining wall block is designed to have an irregular shape so as to have a natural stone shape. However, even if the front of the retaining wall block is designed in an irregular shape, each retaining wall block is the same design eventually, and since such retaining wall blocks are uniformly constructed, irregular shapes are repeatedly expressed regularly.

Therefore, in order to form a structure by retaining wall blocks in harmony with nature, each of the retaining wall blocks must have various shapes, and the retaining wall blocks must be constructed in an irregular order, so that the structure by the retaining wall blocks has a natural appearance.

However, in order to produce the retaining wall blocks of various designs, all the formwork for the production of the retaining wall blocks must be different, which increases the production cost, so the contractor was forced to avoid the production of the retaining wall blocks of the various designs.

As a result, the various inclined and bottom surfaces had a monotonous and artificial appearance as the retaining wall blocks of uniform design were built.

Accordingly, the present invention has been made to solve the above problems, it is possible to mass-produce economically and efficiently the production of retaining wall blocks having a variety of designs, through which the structure constructed by the retaining wall block is combined with the natural environment, the environment-friendly image Retaining wall block manufacturing method and the production of the retaining wall block manufacturing mold to be equipped with the technical problem.

A fourth step of demolding the retaining bottle block formed by curing of the cement mortar from the main body;

Retaining wall block manufacturing method comprising a.

According to the present invention, since the retaining wall blocks can be manufactured and constructed by various designs, each of the retaining wall blocks can be represented by a natural image that harmonizes with nature while showing an irregular appearance, and the retaining wall blocks of various types can be manufactured at a relatively low cost and efficiently. And since it can produce, economic effects can be expected.

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