DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a block such as a retaining wall which can be used for various retaining walls.

[0002]

2. Description of the Related Art Conventionally, as a method of manufacturing blocks for roads, retaining walls, and the like, split stones, slabs, cobblestones, and the like are arranged in a plane in a mold, and agar powder is mixed with water at joints of the stones. After injecting the heated liquid coagulant and setting and hardening it at room temperature, inject mortar and cast concrete,
There has been proposed a method of manufacturing a block in which a coagulant removed from a mold after being cured and attached to the surface of a stone is removed by air or water pressure (for example, see JP-A-3-159703).

Further, water is poured into the exterior material and cooled to integrate the exterior material and ice, and concrete is poured in a state of being solidified with ice, and then heat is applied to melt and remove the ice to remove the exterior wall material. A production method for obtaining a precast concrete secondary product has been proposed (see, for example, JP-A-6-31710).

[0004]

In the former of the techniques described in the prior art, it is possible to arrange various stones in a plane, but it takes time and trouble to arrange the stones in a plane. In particular, a liquid coagulant obtained by mixing and heating agar powder in water is injected into a joint between the joints, and does not have such a strong property even when set and hardened, but rather has a means of removing it later by air or water pressure. This requires a lot of trouble and raises the cost of manufacturing.

[0005] In the latter case, water is frozen to fix the stones in the exterior material in the mold, so that there is a problem that a large amount of power is consumed.

Accordingly, the present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to reduce power consumption for turning water into ice and to reduce time. It is an object of the present invention to provide a method of manufacturing a block such as a retaining wall.

[0007]

Means for Solving the Problems In order to achieve the above object, the invention according to claim 1 of the present invention spreads wet particles containing water in a bottomed form, and includes It is characterized by inserting a stone into the container, freezing and fixing, then filling and filling with ready-mixed concrete.

Here, as the freezing and fixing means, when a stone is inserted into a water-containing wet particle filled in an appropriate amount in a mold and a vibration is given to the mold, the wet particle is integrally adhered to a gap between the stones. This is a means to prevent rock from rocking during freezing, and specifically, a means to prevent concrete from being peeled by placing and contacting ready-mixed concrete to a predetermined position on the surface of the stone protruding from the surface of the particles. Say everything.

[0009] When formed in this manner, when wet particles containing water are used as a method of fixing the stone in the mold, only the amount of water absorbed into the particles is used, and the water contained therein is frozen. Not only power consumption can be saved, but also the time for freezing can be significantly reduced.

[0010] Further, as in the second aspect of the present invention, the mold is filled with wet particles containing a small amount of water, one side of a large stone is arranged on the wet particles, and vibration is given to the mold. After filling the wet particles in the gaps of the large stones, freezing and fixing the wet particles, a small stone is placed between the large stones and the large stones, and the wet particles are again laid on the formwork by giving a vibration to the form. After filling the wet particles in the gap between the large stone and the small stone, freezing and fixing the wet particles, the raw concrete is poured and filled into the upper surface of the large stone and the small stone to finish the surface of the raw concrete, covered and hardened, and then the mold is formed. Is inverted to remove particles after thawing, comrades Oishi and Koishi form a uniform degree of exposure, and concrete joints do not appear on the surface.

Further, when a stone is arranged on the bottom surface of the formwork and wet particles are put on the stone as in the third aspect of the present invention, the degree of exposure of the stone can be increased.

In order to form irregularities on the exposed surfaces of the stones, if the irregularities are formed on the bottom surface of the formwork as in the invention according to claim 4, the exposed surfaces of the stones also have irregularities according to the shape. .
