해중림초 콘크리트 블록의 표면 처리방법{Method for surface treatment of concrete block for artificial reef}Method for surface treatment of concrete block for artificial reef

본 발명은 해중림초 콘크리트 블록의 표면 처리방법에 관한 것으로서, 보다 상세하게는 바다 속에 투입되어 각종 해양생물의 서식 및 성장 촉진의 착생에 유리한 표면조직을 가짐과 동시에 바다 속에서 오랜 기간 동안 내구성을 유지할 수 있도록 해주는 해중림초 콘크리트 블록의 표면 처리방법에 관한 것이다.The present invention relates to a surface treatment method of the seaweed forest concrete block, and more particularly has been put into the sea having a surface structure advantageous for the growth of the growth and growth of various marine life and at the same time maintain durability for a long time in the sea The present invention relates to a method of treating the surface of concrete blocks of seaweeds.

종래의 인공어초 및 해중림초는 일반적으로 콘크리트 재질 및 일반 자연석을 사용하여 왔으며, 최근에는 강제어초와 같은 새로운 재질의 인공어초 및 해중림초들이 개발되고 있다. Conventional artificial reefs and marine deforestation have generally used concrete and natural stone, and recently, artificial reefs and marine deforestation of new materials such as forced reefs have been developed.

상기 인공어초 및 해중림초는 황폐화된 연안 환경을 복원하거나 개선하여 수산자원의 생산성을 높이는 것을 목적으로 하며, 갖추어야 할 요건은 해조류 및 동물들의 서식에 친화적인 효능을 가져야 하며 제조 및 시설 비용이 저렴하면서 효과가 커야 한다는 것이다.The artificial reefs and seaweeds aim to increase the productivity of fishery resources by restoring or improving the devastated coastal environment, and the requirements to be provided should have a friendly effect on the habitat of seaweeds and animals, and the manufacturing and facility costs are low. The effect should be great.

가장 보편적인 콘크리트 인공어초 및 해중림초는의 경우 재료비가 저렴하고 제조공정이 단순하여 생산비가 적게 들기 때문에 한정된 예산으로 많은 양의 인공 어초 및 해중림초를 시설할 수 있다는 매우 좋은 장점을 가진다. 그러나 인공어초 및 해중림초가 가져야 하는 해양생물의 서식 촉진과 관련된 특별한 재질적 기능성이 없다.The most common concrete artificial reefs and deforested grasses have a very good advantage in that they can install a large amount of artificial reefs and deforested grasses on a limited budget because the material cost is low and the manufacturing process is simple and the production cost is low. However, there is no special material functionality related to the promotion of the habitat of marine life that artificial reefs and marine deforestation should have.

최근에 이러한 문제점을 해결하는데 도움이 되는 한가지 방법으로써 다공성 콘크리트를 이용한 인공어초 및 해중림초가 개발되어 실용화 초기단계에 있다. 다공성 콘크리트는 골재의 입도 범위를 조정함으로써 콘크리트의 표면에서부터 내부까지 열린 기공이 분포하도록 제작된다. Recently, as one method to help solve this problem, artificial reefs and seaweeds using porous concrete have been developed and are in the early stage of practical use. Porous concrete is made to distribute open pores from the surface of the concrete to the interior by adjusting the particle size range of the aggregate.

상기 다공성 콘크리트로 만들어진 구조물은 해조류 포자의 착생에 양호한 효과를 가지며 그리고 작은 동물류 등이 콘크리트에 존재하는 열린 기공에 서식할 수 있는 장점을 가지고 있다. The structure made of porous concrete has a good effect on the growth of seaweed spores and has the advantage that small animals and the like can inhabit the open pores present in the concrete.

그러나 상기 다공성 콘크리트 구조물은 강도가 일반 콘크리트보다 약하다는 단점이 있고, 인공어초 등에서 요구되는 압축강도 사양(210Kg/cm2)을 만족한다고 하더라도 바다 속에 시설되는 경우 열린 기공을 통해 해수의 지속적인 침투가 용이하여 내구성이 오래 지속되지 못한다는 치명적인 단점을 가진다.However, the porous concrete structure has the disadvantage that the strength is weaker than the general concrete, even if it meets the compressive strength specification (210Kg / cm 2 ) required by artificial reefs, etc., when installed in the sea is easy to continuously penetrate seawater through open pores It has a fatal disadvantage that durability does not last long.

본 발명은 상기와 같은 종래 문제점을 해결하고자 창안된 것으로서, 그 목적은 각종 해양생물의 서식 및 성장 촉진의 착생에 유리한 표면조직을 가짐은 물론, 바다 속에서 오랜 기간 동안 내구성을 지속적으로 유지할 수 있도록하여 바다 속 환경복원에 기여할 수 있도록 한 해중림초 블록 제조방법을 제공함에 있다.The present invention was devised to solve the conventional problems as described above, the object of which is to have a surface texture advantageous for the breeding and growth of various marine life, as well as to maintain durability for a long time in the sea Therefore, it is to provide a method for manufacturing seaweed forest grasses that can contribute to environmental restoration in the sea.

상기 목적을 달성하기 위한 본 발명의 과제 해결수단은, 인공어초 및 소파블록을 포함하는 해중림초 콘크리트 블록을 만들기 위하여 굵은 골재, 잔 골재, 시멘트, 물로 구성된 콘크리트 재료를 통상의 해당 거푸집에 충입하고, 상기 콘크리트가 충입된 거푸집을 탈형 후 양생 과정에서 당 수용액 또는 산 수용액 중 어느 하나를 상기 양생되는 해중림초 콘크리트 블록의 표면에 고압으로 살포하여 일부 콘크리트를 탈락시킴으로써 블록의 표면 조도를 조절하도록 구성된다.The problem solving means of the present invention for achieving the above object is filled with a concrete material consisting of coarse aggregate, fine aggregate, cement, water in the corresponding formwork in order to make the seaweed forest grass concrete block including artificial reef and sofa block, After demolding the concrete-filled formwork, it is configured to control the surface roughness of the block by dropping some concrete by spraying any one of a sugar solution or an acid solution at high pressure on the surface of the cured seaweed forest concrete block during curing.

이상과 같은 본 발명의 해중림초 블록은 내구성의 지속성을 가지면서 해양생물의 서식 및 성장 촉진에 유리한 표면조직을 가진 해중림초 블록을 제공함으로써 해중림초 조성에 우수한 효과를 가짐은 물론 그에 따른 연안환경 복원에 기여할 수 있는 효과가 있다.As described above, the marine deforestation block of the present invention has excellent durability in the composition of marine deforestation by providing a marine deforestation block having a surface structure that is advantageous in promoting the habitation and growth of marine organisms while maintaining durability, as well as restoring the coastal environment accordingly. There is an effect that can contribute to.

이하에서 본 발명에 따른 해중림초 콘크리트 블록의 표면 처리방법의 기술구성에 대해 보다 상세히 설명한다.Hereinafter will be described in more detail for the technical configuration of the surface treatment method of the seaweed forest grass concrete block according to the present invention.

본 발명은 기존에 일반 콘크리트의 치밀한 내부조직에 의한 내구성과 다공성 콘크리트의 해조류 착생에 유리한 표면조직의 장점을 모두 가지는 콘크리트 블록을 제조하는데 그 기술적 요지가 있다.The present invention has a technical gist of manufacturing a concrete block having both advantages of durability due to the dense internal structure of general concrete and surface texture advantageous for seaweed growth of porous concrete.

이를 위해 본 발명에서는 해중림초 콘크리트 블록의 재료로 최근에 많이 사 용되고 있는 다공성 콘크리트가 아니라 일반 콘크리트를 사용한다. 왜냐하면, 다공성 콘크리트는 넓은 표면적을 제공하는 대신에 엉긴 내부조직에 의해 내구성이 약하기 때문이다. 비록 다공성 콘크리트가 인공어초 등에서 요구되는 압축강도 사양(210Kg/cm2)을 만족한다 하더라도 열린 기공을 통해 해수가 지속적으로 침투하여 내구성이 저하된다는 점은 이미 상기한 바와 같다.To this end, the present invention uses general concrete, not porous concrete, which has been used a lot recently as the material of the seaweed forest grass concrete block. This is because porous concrete is weak in durability due to entangled internal structure instead of providing a large surface area. Although porous concrete satisfies the compressive strength specification (210Kg / cm 2 ) required by artificial reefs, seawater is continuously penetrated through open pores, and durability is as described above.

이러한 이유로 본 발명에서는 일반 콘크리트로 해중림초 블록을 제조한다. 일반 콘크리트 재료인 굵은 골재, 잔 골재, 시멘트, 물를 적정한 비율로 혼합하여 해중림초 블록이 요구되는 일정한 강도가 나오도록 구성된다. For this reason, in the present invention, the seaweed forest grass block is manufactured from ordinary concrete. Coarse aggregate, coarse aggregate, cement, and water, which are general concrete materials, are mixed in an appropriate ratio so that the deciduous forest blocks have a certain strength required.

상기 골재는 모래, 자갈, 쇄석(부순돌), 슬래그 등을 포함하는 것으로서 콘크리트를 만들기 위한 시멘트, 물과 함께 경화된다. 상기 시멘트는 수경성 시멘트의 대표적인 것으로서 보통 구조용이나 마감용으로 많이 사용되는 포틀랜드 시멘트(Portland Cement)나 이 포틀랜드 시멘트에 비해서 조기 강도가 크며 수화열이 높아 해수 공사에 사용하기 좋은 조강 포틀랜드 시멘트(High Early Strength Portland Cement) 등이 사용된다. The aggregate is hardened with cement, water for making concrete as including sand, gravel, crushed stone (crushed stone), slag and the like. The cement is a representative of hydraulic cement, which is usually used for structural or finishing, or Portland Cement, which has a high early strength and high heat of hydration compared to the Portland cement. Cement) and the like are used.

상기한 콘크리트 재료를 통상의 해당 거푸집에 충입하고, 상기 콘크리트가 충입된 거푸집을 탈형 후 일정 기간 동안 양생시킨다. The concrete material is filled in the usual formwork, and the formwork filled with concrete is cured for a period of time after demolding.

본 발명에 따르면, 상기 양생 과정에서 당 수용액 또는 산 수용액 중 어느 하나를 상기 양생되는 해중림초 콘크리트 블록의 표면에 고압으로 살포하여 일부 콘크리트를 탈락시킴으로써 블록의 표면 조도를 조절하도록 구성되며, 이는 본 발 명의 가장 특징적인 기술구성을 이룬다.According to the present invention, in the curing process by spraying any one of the sugar solution or the acid aqueous solution to the surface of the cured seaweed forest concrete block at high pressure is configured to control the surface roughness of the block by dropping some concrete, this foot The most characteristic technical composition of the people.

거친 표면을 가진 콘크리트 블록이 매끄러운 표면을 가진 것보다 해조류의 착생 및 성장에 더 유리하다. 따라서, 본 발명에서는 당 수용액 또는 산 수용액 중 어느 하나를 완전히 양생되지 않은 콘크리트 블록의 표면에 고압으로 분사하여 일부 콘크리트를 탈락시킴으로써 표면 조도를 증가시키는 것이다.Concrete blocks with rough surfaces are more favorable for the growth and growth of algae than with smooth surfaces. Therefore, the present invention is to increase the surface roughness by dropping some of the concrete by spraying at high pressure on the surface of the concrete block is not cured either sugar solution or acid aqueous solution.

일반 물을 사용하는 것보다 당 수용액이나 산 수용액을 사용하면 물리적인 타격에 의한 콘크리트 탈락뿐만 아니라, 화학적인 반응에 의해서도 콘크리트 탈락이 이루어지므로 더욱 효과적으로 표면 조도를 증가시킬 수 있다. 또한, 해중림초 콘크리트 블록이 투하되는 바다의 염도, 착생시키고자 하는 해조류의 종류 및 그 성질 등을 고려하여 적합한 표면 조도가 되도록 조절된다.When using an aqueous solution of sugar or acid rather than using ordinary water, not only concrete dropout due to physical impact, but also concrete dropout by chemical reaction can increase surface roughness more effectively. In addition, it is adjusted to the appropriate surface roughness in consideration of the salinity of the sea to which the seaweed forest concrete block is dropped, the type and nature of the seaweed to be engrafted.
