た。2. Description of the Related Art It is known that a wave breaker such as a tetrapot is loaded on the outside of a breakwater, or a breakwater is built by loading a breakwater, but it damages the landscape and is dangerous if you ride on it. There were problems such as The scenery improves when rocks are placed on the existing breakwaters, but the breakwaters are piled up irregularly, and the small rocks block the gaps of the breakwaters and deteriorate the breakage performance. A large rock that is placed between the legs of the car has problems such as inconvenience in transportation and high cost.

る。Means and Actions for Solving the Problems A fish reef or a construct for a breakwater according to the present invention which achieves the above-mentioned object, is a concrete concrete body composed of upper and lower wing-like portions provided with notches and a central wall-like portion. It is characterized by arranging them side by side to form a tubular water passage between adjacent concrete units, or by arranging them in front and back and stacking them vertically. Since a water passage is formed in the above structure, wave force can be dispersed, and the water passing through the water passage receives resistance at the notch or part of it flows out of the notch, weakening the water force, and before and after the concrete alone. When arranging in a zigzag pattern in the direction, the water in the water passage branches off at the wall-like parts of the concrete placed in front and behind to further weaken the water force and perform wave-dissipating action. The above structure can be used for a breakwater, etc., but the formation of a water passage is effective for raising fish and can also be used for a fish reef.

で景観を損わない。One of the pseudo-stones of the present invention is characterized in that a downwardly projecting ridge is formed on the peripheral edge of the bottom to imitate the surface shape as a rock. Since the above pseudo stone has a downward projecting ridge at the bottom edge, placing the leg and the convex part of the breakwater on the recess formed by the ridge and placing the pseudostone on the breakwater causes Even if you try to move with force, the ridge will be difficult to move because it will lock on the legs etc.When placing the pseudo stone on the wave-dissipating object group, if the ridge interferes and stable placement is difficult, It is easy to cut a part and place it stably. In addition, when it is installed on soil or sand as garden stone or artificial rock, it is difficult for the ridges to bite into the soil or sand and move. If the artificial stone is a hollow body with an opening, it is convenient to carry even if it is upsized, and after installing it on the wave-dissipating material group, add a filling such as fresh concrete or sand from the opening to increase the weight. , You can also increase the breakwater effect, and you can also plant soil with soil. In addition, the surface shape is made to imitate a rock so that the landscape is not damaged.

Since the above pseudo stone is a hollow body, it is lightweight and convenient for transportation, and it can be placed on a group of wave-eliminating substances and then filled with ready-mixed concrete or the like. In addition, the surface shape is made to imitate rocks, so it does not spoil the landscape.

Although it may be manufactured by a conventional technique, it is resistant to freezing and thawing, and hardly absorbs water and has excellent durability when manufactured by the method described below. Water or a lime-based aqueous solution (calcium hydroxide prepared by adding water to slaked lime, quick lime, cement, etc. or an aqueous solution containing mainly this, preferably a saturated aqueous solution) and an AE agent (using Vinsol sold by Yamamune Chemical Co., Ltd.) Use it to make ready-mixed concrete of any mix, pour it into a mold and mold it, and as soon as it does not collapse with water, cover it on the surface after about 3 hours if left alone. If sealed for about 5 hours, water or a lime-based aqueous solution is accumulated on the concrete surface to prevent evaporation of water and cure to form a large amount of gel. Twenty-four hours after molding, if water or lime-based aqueous solution is not accumulated in an appropriate amount, remove it.
When air-cured at 100%, it is dried by water consumption due to hydration reaction, and after 24 hours demolding, carbonation of the mold contact surface due to water evaporation does not occur and primary white flower occurs. Not get concrete. If the formwork is adiabatic, the reaction heat gives 5
The temperature is raised to 0 ° C. or higher, and the temperature is approximately equal to the outside air temperature before demolding. The concrete thus produced has a small number of evaporation holes and low water absorbency, and it becomes harder to absorb water due to the formation of dense calcium carbonate, and the water is hard to evaporate, so that the reaction proceeds further and the strength becomes high. Moreover, air is entrained by the use of the AE agent, which is strong against freeze-thawing. Immediately after molding, it is cured with fine water droplets from an ultrasonic humidifier and then covered with water to further increase the strength. still,
Instead of accumulating water or a lime-based aqueous solution, water or a lime-based aqueous solution may be sprayed and cured in a high humidity atmosphere. Further, after the mold is removed, it is soaked in water or a lime-based aqueous solution to replenish the lacking water, and then subjected to sealed curing or curing in an atmosphere of 100% humidity to further increase the strength. Fresh concrete can be made by adding one or more of a water reducing agent, a fiber and a lightweight aggregate, and it is possible to increase the strength by reducing the water cement ratio, increase the bending strength, and reduce the weight. When the flame of a torch lamp or the combustion gas is blown to the concrete to heat it high, the white flower component is carbonated and the generation of secondary white flower can be suppressed. Even if the reaction liquid that reacts with various admixtures such as water-reducing agents and white-sintered components such as potassium stearate or carboxylic acids is impregnated so that the liquid does not collect on the surface and the reaction liquid and the white-sintered components are reacted, the secondary It is possible to suppress the occurrence of white sinter.
