The present invention relates to a manufacturing method and construction method of the reef block using the step-by-step method, more specifically, by pouring a mixture containing steelmaking slag ready-mixed concrete and cement in the form for manufacturing the reef block "

"Manufacturing a reef block comprising a leg having a cross-section, in the form for manufacturing the reef block, the first pouring step of placing in the lower portion of the formwork becomes narrower from the bottom to the top, to promote air release A method of manufacturing a fishery block using a step-by-step method, characterized in that it comprises a second step of placing in the upper part of the formwork, the rest stage and the width widening from the bottom to the top, and the aquatic organisms can inhabit the ocean It relates to a construction method of Echo block that can provide space efficiently.

Slag, a by-product of iron production in steelworks, is in a liquid state because it is produced in a molten state at high temperatures. The molten slag is solidified through cooling and then crushed according to its purpose. Slag produced through such a conventional treatment process will usually have a particle size of about 30mm or less. Afterwards, it has been adjusted as it is or the size of the appropriate particle size, until now, the use of slag has been mostly concentrated in the field of construction and civil engineering materials, and the research for more efficient use in this field continues.

There are two main types of slag: blast furnace slag generated in the steelmaking process and steelmaking slag generated in the steelmaking process. These two slags are used differently according to their characteristics. In other words, blast furnace slag can produce amorphous granules when rapidly cooled and solidified as water in the molten state due to the nature of the chemical composition, and when it is dried and pulverized into fine powder, it has a hydraulic property similar to cement and is used as a cement and concrete admixture. do. As it is, in case of slow cooling, after removing sulfur (S) through a separate treatment (aging) process, it can be used as a concrete aggregate as well as road aggregate or civil engineering fill material.

Steelmaking slag has a relatively high content of CaO compared to other components, it is difficult to utilize as an aggregate for civil engineering, as it remains in the expanding property without undergoing a separate treatment process. The most common aging treatment of steelmaking slag is natural aging, which is used after eliminating potential expansion by maintaining steelmaking slag in a large place for a certain period of time, and the aging period is adjusted according to the purpose of use.

A limiting factor in the use of steel slag is that it contains a lot of iron in addition to the glass lime described above. The reason why steel slag contains a lot of iron is that the oxygen blown during steelmaking operation oxidizes Fe as well as impurities in molten iron, and this oxidized Fe is slagd into an oxide form. In addition, the metal Fe is also present in the slag because it is not completely separated in the process of separating the molten steel and slag after the converter operation. As described above, iron of the steelmaking slag is present in the form of metals and oxides and accounts for about 20% by weight of Fe. Due to this, steelmaking slag is heavier than other natural aggregates, and has a characteristic of having high hardness. Indeed, this is the most fatal flaw that hampers the use of steelmaking slag. The material itself has excellent properties as civil engineering aggregates, but it is heavy and therefore expensive to transport. In general aggregates, the price of the material itself is not expensive, and most of the selling price is transportation costs. Therefore, the low price of steelmaking slag is a by-product by-product from steel mills.

However, since steelmaking slag contains a lot of lime powder and iron, it is used as a raw material for cement cleaner. Limestone (CaCO ₃ ) accounts for more than 80% of the raw materials for the production of cement clinkers. The main role of steel slag is to lower the melting point in the furnace after the mixture of clinker raw materials enters the cement kiln. It plays an important role in the synthesis of clinker minerals at temperature.

As described above, the main purpose of the slag is mainly for civil engineering because it is almost the only field that can utilize a large amount of slag that occurs in large quantities. . So, slag is now actually being recycled almost entirely.

However, the future outlook for slag utilization is not bright. It is because there are many by-products that can be replaced with slag, and this amount will continue to increase in the future. For example, construction waste. As buildings rapidly removed during the industrialization period, the amount of demolition by end of life continues to increase, and the generation of building wastes is also increasing, and they can be used as recycled aggregates through regeneration processes. Balanced resource recycling requires the development of new uses that can make the slag more environmentally friendly. Among them, the marine sector is a field that can utilize in a large amount in some cases while utilizing the advantages of slag. Among them, artificial reefs are prominent.

Echo blocks are installed to promote the growth of copper, phytoplankton and algae that live in the coastal waters. In conventional artificial reefs, concrete structures and waste tires are used, and there is a risk of environmental pollution due to the concrete structures and waste tires.

The present invention also provides a construction method of the reef block, after tying the rope block with a rope connected to the crane, the construction is carried out by a compact method or a clearance method so that the porosity between the reef block is 45 ~ 65%.

According to the present invention, it is possible to suppress the generation of bubbles commonly found in conventional reef blocks by using the method of pouring the raw material of the reef block several times in step, thereby producing a reef block having improved durability such as strength. Can be. In addition, it is possible to reduce the amount of fermentation of the reef block while improving the porosity during the construction of the reef block can provide an economical effect and the optimal space for algae habitat.

The present invention in one aspect, (a) preparing a mixture of steelmaking slag concrete, cement and water; (b) pouring the mixture stepwise into the formwork; (c) vibrating compaction in which the mixture is poured; (d) troweling the surface of the mixture; (e) dismantling the formwork to obtain a molding; And (f) curing the molded article to obtain a fish block, wherein the formwork including the hollow frame 21 for forming the hollow is the body portion 12 in which the hollow 11 is formed; Hollow forming center frame 21 and body frame 22 corresponding to the hollow 11, the body portion 12, and the leg portion 13 of the reef block, so as to manufacture the reef block including the leg portion 13. And a leg 23, the hollow 11 is formed, using a step-wise pour method, and a method for manufacturing a reef block comprising a body portion 12 and a leg portion 13 will be.

Echo block to be manufactured in the present invention includes a body portion 12 and the leg portion 13, the hollow portion 11 is formed in the body portion 12, the leg portion 13 is three. The hollow 11 serves to provide a habitat for seaweeds (FIG. 1).

On the other hand, the formwork for manufacturing the reef block comprising the body portion 12 and the three leg portion 13, the hollow 11 is formed is hollow 11, the body portion 12 and Hollow forming center frame 21, the body frame 22 and the leg frame 23 corresponding to the leg portion (13).

On the other hand, in the present invention, it is preferable to assemble the formwork in advance in order to manufacture the eocho block, and to look at the assembly process, as shown in Figure 2, after placing the pallet (Fig. 2 (a)), the side plate Of the installation (Fig. 2 (b)), the bottom plate installation (Fig. 2 (c)), the bottom plate installation (Fig. 2 (d) and (e)) and the top plate and the center frame installation (Fig. 2 (f)) Can be assembled through the process.

In the present invention, the step-by-step method is a pour after the first pouring step (Fig. 3 (a)), the resting step (Fig. 3 (b)) and the second pouring step (Fig. 3 (c)) It means the pour method (figure 3 (d)) to complete.

That is, in the present invention, the step-by-step of the step (b) comprises (a) a first step of pouring the mixture so that 45 to 55% of the form capacity is filled; (b) a step of restraining the generation of bubbles in the fish block produced by promoting the ejection of air generated after the first pouring step; And (c) a second pouring step of pouring the mixture to fill the entire formwork of the formwork.

Hereinafter, the reason for using the step-by-step method in the present invention. The overall appearance of the formwork used in the present invention is the form of the lower portion is wider and narrower toward the middle portion, and then wider toward the upper portion again.

When the raw material containing steelmaking slag conical and cement is fixed at once in the formwork, air generated inside the raw material is generated and moves upward. However, since the lower portion of the formwork becomes narrower from the lower end to the upper end, the pores are formed in the inside of the estuary block which is manufactured by being unable to eject to the outside by the formwork having the narrower air. In addition, traces of air remain on the contact surface with the formwork, so that traces such as pimples are formed on the surface of the prepared reef block, so that the reef block having a clean surface cannot be obtained. As a result, when the fish block is manufactured through a single casting on the formwork having a shape determined by the lower portion that becomes narrower from the lower portion to the upper portion and the upper portion that becomes wider from the lower portion to the upper portion, strength and durability And there is no choice but to produce a block of eocho blocks with poor surface properties.

However, when the stepping method is applied to the formwork having a shape determined by the lower part that becomes narrower from the lower part to the upper part and the upper part that becomes wider from the lower part to the upper part, when one brewing is performed Problems that occur can be solved.

In the step-by-step method including a first pour step, a resting step and a second pour step, the first pour step is to be placed in the formwork, but only to the lower portion narrower from the bottom to the top, Preferably, the mixture is poured so that 45-55% of the form capacity is filled. The resting step following the first pouring step stops the pouring operation to minimize the generation of bubbles in the echo block produced by promoting the air from the poured raw material to be blown out to the outside, and at the same time, to prevent the occurrence of pimples on the surface of the echo block. It is a step to keep it. The second pouring step following the rest step is to place the formwork, in order to be placed in the upper portion, which is wider from the bottom to the top, so that the entire capacity of the formwork is filled.

" 형상의 단면을 가지는 다리부를 포함하는 어초 블록을 제조하기 위하여 적절한 타설법이다.A first pouring step as described above; Rest phase; By using a step-by-step casting method comprising a second pouring step, it is possible to manufacture a reef block with improved strength, durability and surface properties, in particular, the step-by-step pouring method "

Is a suitable casting method for producing a reef block comprising a leg having a cross-section in the shape.

Meanwhile, in the present invention, the mixture may be prepared by mixing 10-25 parts by weight of cement and 10-20 parts by weight of water with respect to 100 parts by weight of the steelmaking slag concrete. If the amount of the cement used is less than 10 parts by weight, it is not possible to obtain an appropriate strength as a fish block, and if it exceeds 25 parts by weight, there is no benefit from the increase in the amount used. If the amount of water used is less than 10 parts by weight or more than 20 parts by weight, molding is not easy.

In the present invention, the center frame 21, the body frame 22 and the leg 23 of the formwork are connected by a connection portion fastened by a bolt and nut coupling, to facilitate the assembly and disassembly of the formwork The nut may be formed integrally with the formwork.

Specifically, the nut is integrally formed in the formwork by welding to shorten the coupling time of the bolt and nut when assembling and disassembling the form, and to shorten the coupling time of the bolt and nut during assembly and disassembly, Disassembly can be facilitated.

The above-described method of manufacturing a reef block may be applied regardless of the weight of the reef block to be manufactured, and specifically, 0.5 to 50 ton of reef blocks may be manufactured.

In the present invention, the curing may be characterized in that the wet curing for 26 to 27 days. When the curing period is set to 26 to 27 days, the physical properties of the fish block finally produced is excellent. During curing, protect the moldings in the shape of the reef block from sunlight, cover the curing cloth to prevent cracking due to rapid drying, and do not apply the impact to the molding under curing from the outside.

After pouring the step-by-step, by removing the formwork through the vibration compaction and trowel finishing process it is possible to obtain a molded article in the form of a reef block. As shown in Figure 4, the process of disassembly of the formwork, as shown in Figure 4, the separation of the center frame (Fig. 4 (a)), the upper and lower plate separation (Fig. 4 (b)), the side plate separation (Fig. 4 (c)) The formwork can be dismantled through the steps of separating the base plate (FIG. 4 (d)), removing the pallet (FIG. 4 (e)) and obtaining the molded product (FIG. 4 (f)). At this time, when separating the center frame, the compressive strength of the molding is preferably desorbed in the initial curing step of 2.0Mpa ~ 3.0Mpa to facilitate the dismantling of the formwork.

In another aspect, the present invention is characterized in that the hollow 11 is formed and the body portion 12 and the body portion 12, characterized in that it is manufactured by a step-by-step pour method does not have a pore phenomenon of pores and surfaces therein It relates to a reef block comprising a leg portion 13 is integrally coupled to.

Since the reef block is manufactured by the stepwise pouring method, air generated during the manufacturing process is ejected, so that there is no pores therein and no pimples appear on the surface, so that the strength, durability and surface characteristics are improved compared to the conventional reef block. It features. In addition, the body portion 12 is formed with a hollow 11 can provide a sufficient space for the inhabitants, such as seaweeds.

According to another aspect of the present invention, after tying the eocho block with a rope connected to the crane, the construction method of the eocho block, characterized in that the construction by dense or marginal method so that the porosity between the eocho block is 45 ~ 65% It is about.

If the porosity between the reef blocks constructed by the above construction method is less than 45%, it is not possible to provide enough space for the aquatic life, and when it exceeds 65%, the space is formed excessively wide to cover the reef blocks The effect is reduced. Preferably, the porosity may be 56%.

In the present invention, the dense method may be characterized in that the method is constructed in the form that the legs 13 of the adjacent three reef blocks are hunted to one point (Fig. 5). When the construction is dense, there is an advantage to maximize the coating effect.

In the present invention, the clearance method may be characterized in that the construction method is constructed in such a way that the legs 13 of the six adjacent reef blocks converge to one point (FIG. 6). In case of construction by spare method, there is an advantage that can minimize the construction quantity of Eocho block.

On the other hand, when constructing the echo block using a crane, using a rope connected to the crane is tied up to lift the echo block to construct. Specifically, it is preferable to use a crane by hanging on a hook (FIG. 7).

In the present invention, the structure of the portion of the rope is in contact with the reef block is made of a fiber material on the outside and the inside is made of steel wire, the structure of the portion of the rope is not in contact with the reef block is made of a wire with strong tensile force It may be characterized by.

When using a rope as described above, there is an advantage that can be transferred and construction without damaging the surface of the echo block. In addition, the construction of the rope can be performed more efficiently by changing the rope knotting method according to the weight of the fish block.

When transferring and constructing the reef block, if the weight of the reef block is 0.5 to 10 tons depending on the weight, construct the reef block by knotting the rope using a two-line simple bundle method (Fig. 8 (a)), Up to 12 to 50 tons of weight is to construct a reef block by knotting rope using a three-line safety bundle method (Fig. 8 (b)) or a three-line upper bundle method (Fig. 8 (c)). Since the rope knot method is changed according to the weight, it is possible to improve the work efficiency, and even if the weight is heavy, there is an advantage that can be safely installed the reef block. Here, the two-line simple bundle method is a method of tying two ropes to the leg portion of the Echo block (Fig. 8 (a)), the three-line safety bundle method is made of three loops each with three ropes After inserting into the leg portion of the Echo block and tied (Fig. 8 (b)), the three-line upper bundle method is three ropes each made of three loops and inserted into the middle of the leg portion of the Echo block one It is a method of tying by connecting with a string (Fig. 8 (c)).

On the other hand, using the two-line simple bundle method and the three-line safe bundle method can be constructed in the echo block inclined place. Specifically, when using a simple two-wire bundle method, one of the two ropes (wires) can be constructed using a shorter rope than the other rope (Fig. 9 (a)). In the case of using the three-row safety bundle method, one of the three ropes (wires) can also be constructed using a shorter rope than the other two ropes (FIG. 9 (b)).

In addition, in the case of constructing the eocho block according to the dense or spare method, in addition to the construction of the eocho block in a single layer can also be installed by stacking in two stages (Fig. 10 (a)), three steps of stacking It is also possible to carry out construction by (b)) and four steps of loading (FIG. 10 (c)).

In the present invention, in order to prevent the twisting of the rope may be characterized in that the buoy is attached to the rope, the rope knot method may be characterized in that it depends on the weight of the fish block (Fig. 11).

When buoys are attached to the ropes during the construction of the Eocho block, the ropes are prevented from being twisted, which has the advantage of preventing safety accidents and improving workability of construction.

According to the present invention, by using the step-by-step method of pouring the raw material of the reef block at once without dividing it can suppress the generation of bubbles commonly found in conventional reef blocks, the durability of strength and the like Blocks could be produced and cracks could be prevented. In addition, it is possible to increase the economic effect and sometimes to increase the coating effect through the difference between construction methods through the clearance method that reduces the amount of fermentation of the reef block by maximizing the pore rate by adjusting the porosity according to the purpose of construction of the reef block. The construction method can provide an optimal space for a stable fishing port or harbor and algae habitat.

Hereinafter, the present invention will be described in more detail with reference to the following examples. These examples are intended to illustrate the present invention in more detail, and it will be apparent to those skilled in the art that the scope of the present invention is not limited to these examples.
