Abstract
Description
본 발명은 고성능 투수블록의 제조방법에 관한 것으로, 더욱 상세히는 집중호우나 우천시 우수의 배출과 투수율은 높이면서도 상부층의 강도저하와 균열 등을 방지하며 내구성이 우수한 고성능 투수블록의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a high-performance permeable block, and more particularly, to a method of manufacturing a high-performance permeable block having excellent durability while preventing strength reduction and cracking of the upper layer while increasing the discharge and permeability of rainwater during concentrated torrential rain or rain. .
일반적으로 보도 블록은 다양한 색깔과 모양으로 인해 보도, 광장, 지하도 등과 같이 자동차가 통행하지 않는 장소의 포장에 주로 사용된다.In general, sidewalk blocks are mainly used for paving places where cars do not pass, such as sidewalks, squares, and underpasses due to their various colors and shapes.
종래의 보도블럭은 일반 보도블럭과 같이 물을 통과시키지 아니하는 것이 주종을 이루었으나, 강우량이 일정량 이상으로 증가하게 되면 증가된 우수량을 처리할 수 있는 처리 시설의 용량부족으로 인해 저지대에 홍수 등의 침수 피해가 발생하게 된다.Conventional sidewalk blocks do not allow water to pass through like general sidewalk blocks, but when rainfall increases above a certain amount, floods in lowlands due to insufficient capacity of treatment facilities capable of handling the increased rainfall. Inundation damage will occur.
이에 따라 최근에는 자갈 등과 같은 골재를 시멘트와 물 및 에폭시 수지를 혼련하여 블럭화한 투수성 보도블럭이 생산되었다. 그러나, 종래 투수성 보도블럭은 별도의 투수를 위한 구조를 갖는 것이 아니라, 물의 배수를 용이하게 하기 위하여 그 하측에 자갈 등을 포함한 별도의 투수층을 시공함으로 인하여 시공작업이 난해하게 되며, 이에 따른 비용도 상승하게 되는 문제점이 있었다.Accordingly, in recent years, a water-permeable sidewalk block was produced in which aggregates such as gravel were mixed with cement, water, and epoxy resin to block. However, the conventional water permeable sidewalk block does not have a separate structure for permeation, but construction work becomes difficult due to the construction of a separate water permeable layer including gravel, etc. underneath it to facilitate water drainage. There was also a problem of rising.
또한, 종래 투수성 보도 블럭은 하부로 빗물 등을 원활히 투수시키지 못하기 때문에 결과적으로 표면으로 우수가 범람하여 지하수로 유입되지 못하고 표면에서 유수되어 결국 하천을 범람시키게 되는 문제점이 있었다.In addition, since the conventional water permeable sidewalk block does not smoothly permeate rainwater or the like to the bottom, as a result, rainwater overflows to the surface, so that it cannot flow into the groundwater, flows from the surface, and eventually floods the river.

본 발명은 종래의 문제점을 해결하기 위해 고성능 투수블록에 다수의 수직통공과 배수구를 형성시켜 갑작스러운 집중호우나 폭우시 우수가 빠르게 바닥으로 배출되고 지면으로 자연배수되어 지반의 부등침하 등을 방지할 수 있게 하며, 상부측에 산화그래핀을 사용하여 휨강도와 압축강도를 크게 향상시키며 내구성과 강도가 높아져 외부충격 등에 의해 상부층에 균열이 생기거나 표면이 탈리되는 것을 막을 수 있는 고성능 투수블록의 제조방법을 제공하는데 목적이 있다. In order to solve the conventional problems, the present invention forms a number of vertical holes and drains in a high-performance permeable block, so that rainwater is quickly discharged to the floor in case of sudden concentrated torrential rain or heavy rain, and is naturally drained to the ground to prevent differential subsidence of the ground. A high-performance water permeable block manufacturing method that can prevent cracks or surface separation due to external impacts due to increased bending strength and compressive strength by using graphene oxide on the upper side and increasing durability and strength. There is a purpose to provide.

본 발명은 갑작스러운 집중호우나 우천시 우수가 각 통수공에 의해 빠르게 배출되고 배출된 우수는 바닥면의 배수구로 유입되면서 지반으로 자연배수됨으로써 우수의 투수효율을 높여 우수가 넘치는 현상과 보도 표면에 우수의 고임현상과 지반의 부등침하 현상을 방지하고, 상부층의 강도와 내구성이 향상되어 외부충격에 의한 상부층의 균열이나 표면 탈리현상을 방지하여 투수블록의 수명을 오랫동안 지속시킬 수 있는 효과가 있다.In the present invention, in the event of a sudden concentrated torrential rain or rain, rainwater is rapidly discharged by each passing hole, and the discharged rainwater is naturally drained into the ground as it flows into the drain on the floor, thereby enhancing the permeability efficiency of the rainwater, and the phenomenon of overflowing rainwater and excellence on the sidewalk surface. It has the effect of preventing the phenomenon of sedimentation of the ground and the unequal settlement of the ground, and improving the strength and durability of the upper layer, preventing cracks or surface detachment of the upper layer due to external impact, thereby prolonging the life of the permeable block for a long time.

도 1 및 도 2에 도시된 바와 같이, 본 발명의 고성능 투수블록은 사각형태의 몸체부(10)로 이루어지고, 몸체부(10)에는 복수의 통수공(100)과 복수의 배수구(110)가 형성된다.1 and 2, the high-performance water permeable block of the present invention is made of a

이때, 상기 통수공(100)은 원형의 형태이거나 또는 배출효율을 더욱 높이기 위해 십자의 형태로 형성될 수 있다.In this case, the water-through
상기 몸체부(10)는 투수성은 높이고 강도는 향상시킬 수 있게 입도 8~13mm의 골재 70~80중량부, 시멘트 20~30중량부로 혼합되어 조성되는 하부층(11)과, 시멘트 70~80중량부, 입도 0.5~1mm의 규사 10~20중량부, 산화그래핀 0.010~0.025중량부, 팽창제 1~5중량부, 고유동화제 0.1~2.0중량부로 혼합되어 조성되는 상부층(12)을 포함하여 이루어진다.The
상기 하부층(11)의 혼합물에 사용되는 골재는 공극률을 높여 투수성이 확보될 수 있게 입도 8~13mm의 크기를 사용하는 것으로 입도 8mm 크기 이하일 경우 골재와 골재 사이의 공간이 좁아 우수 등을 투수하기 어려우며, 13mm 크기 이상일 경우 골재와 골재 사이의 공간이 넓어 투수효과는 향상되나 그 강도 및 내구성이 저하되는 문제가 있어 골재는 입도 8~13mm 크기를 사용하는 것이 바람직하다.The aggregate used in the mixture of the lower layer 11 uses a size of 8 to 13 mm in order to secure water permeability by increasing the porosity.If the particle size is less than 8 mm, the space between the aggregate and the aggregate is narrow, so that excellent permeability, etc. It is difficult, and if the size is 13mm or more, the space between the aggregate and the aggregate is wide, so that the water permeability is improved, but there is a problem that the strength and durability are deteriorated. Therefore, it is preferable to use a particle size of 8 to 13mm for the aggregate.
상기 몸체부(10)의 하부층(11) 외주면에는 블록의 시공시 인접되는 몸체부(10)와 소정간격으로 이격되면서 몸체부(10)간에 틈새가 발생하여 시공되게 소정크기로 돌출된 이격돌부(120)가 복수개 형성되어 몸체부(10)간에 형성되는 이격공간(틈새)으로 우수의 배출이 빠르게 이루어짐으로써, 몸체부(10)간의 틈새 투수 및 자체 투수기능이 월등히 우수하여 투수블럭의 백화 현상 및 색상 탈색을 방지할 수 있게 한다.The outer circumferential surface of the lower layer 11 of the
상기 골재는 마사토, 규석, 돌로마이트, 석회석 중에서 선택된 어느 하나 또는 둘이상의 천연골재를 사용하는 것이 바람직하다.It is preferable to use one or two or more natural aggregates selected from masato, silica, dolomite, and limestone as the aggregate.
상기 마사토는 화강암이 풍화되어 생긴 흙으로 화강토로도 불리고, 지구의 지층분포상 상당량이 존재하고, 국내 지층에서는 60%이상으로 분포되어 있어서 양적으로 충분하며, 그 분포위치가 지리적으로 접근이 용이한 하천 주변에서 낮은 구릉이나 산으로 산재되어 있어서 개발이 용이하다. 마사토는 돌과 같은 형태이며 배수성과 통기성 좋은 특징이 있어 밭작물이나 조경수식재, 야생화, 분재, 화분이나 공원 및 하천 산책로 등에 많이 사용되고 있다.Masato is the soil formed by weathering granite, and is also called granite soil, and there is a significant amount of the earth's stratum distribution, and it is distributed over 60% in the domestic stratum, so it is quantitatively sufficient, and its distribution location is around a river that is geographically accessible. It is easy to develop because it is scattered in low hills or mountains in. Masato is a stone-like shape and has good drainage and breathability, so it is widely used for field crops, landscaping plants, wildflowers, bonsai, pots, parks, and river trails.
상기 규석은 주로 석영으로 이뤄진 광물로 순도가 높은 흰을 백규석이라고 하고 그중 페그마타이트에 포함된 것을 장규석이라고 한다. The silicate is a mineral mainly composed of quartz, and white silica with high purity is called white silica, and those contained in pegmatite are called janggyuseok.
상기 규석은 경도와 강도 등을 구현하여 기계적 내구성 향상 및 내화학성을 증진시키는 물성을 갖는 것으로, 내약품성이 우수하며, 흡수율이 적어 산화 및 부식이 없어 보도블럭의 내구성을 높여주는 효과가 있고 천연광물이기 때문에 환경오염 문제가 발생하지 않는 장점이 있다.The silica stone has physical properties that improve mechanical durability and chemical resistance by implementing hardness and strength, and has excellent chemical resistance, low absorption rate, so there is no oxidation and corrosion, so it is effective to increase the durability of sidewalk blocks, and is a natural mineral. Because of this, there is an advantage that environmental pollution problems do not occur.
상기 돌로마이트는 백운석이라고도 하며 삼방정계에 속하는 탄산염 광물이며, 무색, 백색, 회색 따위의 빛깔을 띠는 마름모 모양의 결정이다. 내화 벽돌의 원료로 많이 쓰이며, 염기성염(물에 용해될 경우 물의 pH값을 높이는 염)에 해당하고 칼슘과 마그네슘을 함유하고 있다.The dolomite, also known as dolomite, is a carbonate mineral belonging to the trigonal system, and is a rhombus-shaped crystal that has colors such as colorless, white, and gray. It is widely used as a raw material for refractory bricks, corresponds to a basic salt (a salt that raises the pH value of water when dissolved in water) and contains calcium and magnesium.
돌로마이트의 주요 화학성분은 CaO, MgO, SiO2, Al2O3, 및 Fe2O3이며 원적외선 및 음이온이 방출되어 인체에 무해하며, VOC's 방출 억제 등 친환경 기능성을 발휘하는 장점이 있다. The main chemical components of dolomite are CaO, MgO, SiO 2 , Al 2 O 3 , and Fe 2 O 3, and far-infrared rays and negative ions are released, making it harmless to the human body, and exhibiting eco-friendly functions such as suppressing VOC's emission.
상기 석회석은 탄산칼슘을 주성분으로 하는 퇴적암을 말하며, 백색, 회색 또는 암회색, 흑색을 띠며, 괴상 또는 층상을 이루는 것으로 입자의 크기에 따라 석회질 루다이트, 석회질 아레나이트, 석회질 루타이트로 분류된다. 국내에서는 석회석이 100억톤 정도로 매장되어 있어 개발이 용이하여 다양한 분야에서 사용되고 있다. The limestone refers to a sedimentary rock containing calcium carbonate as a main component, and has a white, gray or dark gray, black color, and forms a lump or layer, and is classified into calcareous rudite, calcareous arenite, and calcareous rutite according to the size of the particles. In Korea, about 10 billion tons of limestone is buried, so it is easy to develop and is used in various fields.
상기 마사토, 규석, 돌로마이트, 석회석 중에서 선택된 어느 하나 또는 둘 이상의 천연골재는 70중량부 미만인 경우 시멘트의 사용량이 많아지면서 투수성이 약해지고 80중량부 이상인 경우 각 성분의 효과가 약해지고 내구성이 약해지는 문제가 발생하여 70~80중량부를 사용하는 것이 바람직하다.If any one or two or more natural aggregates selected from among the massato, silica stone, dolomite, and limestone are less than 70 parts by weight, the amount of cement used increases and the water permeability weakens, and if the amount is 80 parts by weight or more, the effect of each component is weakened and durability is weakened. It is preferable to use 70 to 80 parts by weight.
상기 상부층(12)의 혼합물로 사용되는 산화그래핀은 그래핀을 전처리하여 불순물이 제거된 상태에서 산화시켜 얻어진 조성물로 그래핀은 탄소 6개가 육각형을 이루고 있고 원자 1개의 두께를 갖는 얇은 막으로 이루어진 반금속성 물질로 구조적, 화학적으로 매우 안정할 뿐만 아니라, 우수한 기계적 물성과 뛰어난 전기, 열 전도체로서의 특징을 가지고 있다. 또한, 비표면적이 2,000~3,000m2/g으로 매우 높으며, 철의 100배 정도의 인장강도, 수소나 헬륨 원소도 차단하는 높은 기밀성을 가져 내구성이 우수한 소재이다.Graphene oxide used as a mixture of the
상기 산화그래핀은 시멘트와 결합되면서 강도, 특히, 휨강도는 60%, 압축강도는 30% 향상시킴과 동시에 공극을 충진시키는 필러효과에 의해 상부층의 차염성, 방수성, 내식성, 내마모성 등의 내구성과 강도를 크게 향상시켜 외부 충격 등에 의해 상부층에 균열이 생기거나 표면이 탈리되는 것을 막을 수 있게 하는 것으로 상기 산화그래핀은 적은 양의 사용에 의해서도 강도발현이 이루질 수 있으나 0.010중량부 미만이면 강도발현 효과가 저하되고, 0.025중량부를 초과하면 강도발현 효과는 높아지나 작업성이 불량해지고, 경제성이 저하되는 문제가 있어 산화그래핀은 0.010~0.025중량부를 사용하는 것이 바람직하다. 또한, 제조시 특성에 따라 유동성이 떨어지는 경우에는 고성능감수제를 시멘트에 0.5∼1.5중량부 범위내서 사용도 가능하다.The graphene oxide is bonded with cement to improve strength, in particular, flexural strength by 60% and compressive strength by 30%, and at the same time, durability and strength of the upper layer such as flame retardancy, waterproofness, corrosion resistance, and abrasion resistance due to the filler effect that fills the voids. The graphene oxide can be used in a small amount to prevent cracking or desorption of the upper layer by greatly improving the strength.However, if it is less than 0.010 parts by weight, the effect of developing strength Is lowered, and if it exceeds 0.025 parts by weight, the effect of exhibiting strength is increased, but workability is poor, and there is a problem that economic efficiency is lowered. Therefore, it is preferable to use 0.010 to 0.025 parts by weight of graphene oxide. In addition, when the fluidity is poor according to the characteristics during manufacture, a high-performance water reducing agent can be used in the range of 0.5 to 1.5 parts by weight in cement.
상기 팽창제는 칼슘설퍼알루미네이트, 무수석고, 산화칼슘 등이 단독 또는 2가지 이상 혼합되어 사용될 수 있는 것으로 시멘트 조성물의 조직을 치밀하게 하여 균열과 수축을 방지하기 위해 사용되는 것으로, 상기 팽창제는 2중량부 미만일 경우 균열과 수축방지 효과가 미약할 수 있고, 5중량부 이상일 경우 빠른 경화특성, 과팽창으로 인해 물성에 나쁜 영향을 줄 수도 있으며, 제조 원가가 높아져 경제적이지 못한 문제가 있어 팽창제는 1~5중량부로 사용되는 것이 바람직하다.The expanding agent is calcium sulfur aluminate, anhydrite, calcium oxide, etc., which can be used alone or in combination of two or more, and is used to prevent cracking and shrinkage by densifying the structure of the cement composition. If it is less than part, the effect of preventing cracking and shrinkage may be weak, and if it is more than 5 parts by weight, it may adversely affect physical properties due to rapid hardening and over-expansion, and there is a problem that is not economical due to high manufacturing cost. It is preferably used in 5 parts by weight.
상기 상부층(12)의 혼합물에는 일라이트, 제올라이트, 벤토나이트에서 선택된 어느 하나 또는 둘 이상의 분말 5~10중량부가 더 혼합될 수 있는 것으로 상기 일라이트, 제올라이트, 벤토나이트에서 인체에 유익한 원적외선 및 음이온이 다량 방출되어 우수의 정화기능과 환경 친화적인 투수블록을 제공할 수 있게 한다.In the mixture of the
상기 고유동화제는 칼슘알루미네이트, 무수석고 등의 입자와 입자 사이에 윤활막을 형성하여 주입성을 향상시키기 위해 사용되며 고유동화제로는 폴리카르본산계 또는 나프탈렌 설폰산염계 또는 이들을 혼합하여 사용하도록 한다.The superfluidizing agent is used to improve injectability by forming a lubricating film between particles such as calcium aluminate, anhydrite, and the like, and polycarboxylic acid-based or naphthalene sulfonate-based or a mixture thereof is used as the superfluidizing agent. .
상기 고유동화제는 0.1중량부 미만이면 유동성 증진효과를 얻기 어려우며, 2중량부 이상이면 재료분리 현상이 생겨 0.1~2.0중량부를 사용하는 것이 바람직하다.If the superfluidizing agent is less than 0.1 parts by weight, it is difficult to obtain a fluidity enhancing effect, and if it is 2 parts by weight or more, it is preferable to use 0.1 to 2.0 parts by weight due to material separation.
