따라서 본 발명의 목적은 상기한 종래의 흙포장이 갖는 제반문제점을 해소하기 위한 것으로, 하부층은 골재를 10 ~ 20cm로 포설하고 진동 로울러로 압력을 가하여 95%이상의 다짐 밀도를 확보하고, Therefore, an object of the present invention is to solve all the problems of the conventional soil pavement, the lower layer is installed in the aggregate 10 ~ 20cm and pressurized with a vibration roller to secure a compaction density of more than 95%,
토양은 일반적으로 지표에서 얻어지는 붉은 색의 진흙(적점토)과 황토 등의 점질토와, 고령토, 백토, 마사토 등의 사질토 등이 가능하며, 토양의 종류는 특별히 한정되지는 않으나, 대체로 입경이 0.8∼ 0.005mm인 실트성분과 세립질 및 과립의 입자가 30% : 40% : 30% 정도의 비율로 적당히 섞여있는 것이 바람직하다. Soil is generally red clay (red clay) and clay clay such as ocher and sandy soil such as kaolin, white clay and masato, etc., and the soil type is not particularly limited, but the particle size is generally 0.8 to 0.005. It is preferable that the silt component of mm, particles of fine granules and granules are properly mixed at a ratio of 30%: 40%: 30%.
특히, 본 발명에서는 여러 가지 점토입자의 특성이 골고루 섞여 있는 규석광산으로부터 발생된 표층토를 사용하였으며,Particularly, in the present invention, the surface soil generated from the silica mine is mixed with the characteristics of various clay particles.
본 발명에 따른 탄성 흙포장재는 MMA수지 바인더에 탄산칼슘(CaCO3)과 토사를 배합하여 이루어진다. 상기 Methyl Methy Acrylate 바인더는 에스테르, 아크릴 또는 메틸 메타크릴염을 기초로 한 화학적 합성물로서, 그 특징은 탄소 이중결합 집합체(C=C)이다. 이 제품 체계의 중요 화학구조는 CH2=(CCH3)COOH 이며, The elastic soil packaging material according to the present invention is made by mixing calcium carbonate (CaCO3) and earth and sand in the MMA resin binder. The Methyl Methy Acrylate Binder is a chemical compound based on ester, acrylic or methyl methacrylate salts, characterized by a carbon double bond aggregate (C = C). The important chemical structure of this product system is CH 2 = (CCH 3 ) COOH,
반응 수지의 경화는 제2성분으로, 분말경화 촉진제(BPO)를 첨가해서 만드는 것이다. 상기 분말경화 촉진제는 전체적 경화를 달성하기 위해서, 반응 수지에는 분말경화 촉진제가 화학적 경화를 시도하는 유일한 기능을 갖고있고 분말경화 촉진제는 화학적 반응에서 촉매제로서 작용하므로 완전히 양생된 수지의 물성에는 영향을 주지 않는 것이다.Hardening of reaction resin is made by adding a powder hardening accelerator (BPO) as a 2nd component. In order to achieve the overall curing, the powder curing accelerator has a unique function of attempting to chemically harden the powder curing accelerator in the reaction resin, and the powder curing accelerator acts as a catalyst in the chemical reaction, thus not affecting the physical properties of the fully cured resin. Will not.
따라서 분말경화 촉진제의 분량은 온도에 따라 변화될 수 있으며, 양생과정 중에는 긴 탄소분자(-C-C-C-) 고리가 생성되어, 자연환경과 사용연도의 영향하에서 견디는 특성을 부여하는 것이다. Therefore, the amount of the powder hardening accelerator can be changed according to the temperature, and during the curing process, a long carbon molecule (-C-C-C-) ring is generated, which gives the property to endure under the influence of the natural environment and the year of use.
그리고 상기 탄산칼슘과 토사는 통상적인 필러로서 사용되는 것으로, 탄산칼슘은 그 입도가 약 600mesh의 것을 이용하는바, 입경이 8㎛로서 탄성 MMA수지 바인더에 혼합되어 강도를 증진시키면서 자기수평성을 확보하기 위함이며, In addition, the calcium carbonate and the earth and sand are used as a conventional filler, the calcium carbonate is used as the particle size of about 600 mesh, the particle size is 8㎛ to be mixed in the elastic MMA resin binder to increase the strength while ensuring the self-horizontality For the sake of
상기 표층토는 입자의 크기가 212㎛ 미만(평균입경이 50㎛)인 것 30 ~ 50wt%의 범위를 가지며,212㎛ 이상 ∼ 2mm 이하의 입자가 50 ~ 70wt% 범위인 것으로 점질과 사질이 적당히 혼합되어 있는 오염되지 않은 토양을 이용하는바, 그 이유는 MMA수지 바인더와 혼합되어 강도를 증진시키면서 수밀성을 저하 시키지 않는 입경이기 때문이다. The surface soil has a particle size of less than 212㎛ (average particle diameter is 50㎛) has a range of 30 ~ 50wt%, particles of 212㎛ or more ~ 2mm or less is in the range of 50 ~ 70wt%, the viscosity and sand mixed properly The uncontaminated soil is used because it is mixed with the MMA resin binder and has a particle size that does not lower the watertightness while increasing the strength.
또한 단위중량이 1.7ton/㎥로서 흙콘크리트의 비중보다 가볍고, 전체 두께5cm의 흙포장체를 형성함으로써, 자체 중량의 감소 및 흙포장체의 자체탄성력과 인장강도 및 수밀성으로 방수성 및 내구성을 확보하는 것이다. In addition, the unit weight is 1.7ton / ㎥, which is lighter than the specific gravity of the soil concrete, and forms an earthen package with a total thickness of 5cm, thereby ensuring waterproofness and durability by reducing its own weight and its elasticity, tensile strength, and watertightness. will be.
상기와 같은 흙포장재는 충진재인 탄산칼슘과 토사 혼합물 85 ∼ 75중량%에 MMA수지 바인더 25 ∼ 15중량%에 배합되어 사용되는바, 이는 바인더의 배합비가 10중량% 미만이면 경화가 이루어지지 않아 바닥재로서의 기능이 나타나지 않고 25중량%를 초과하더라도 더 이상의 강도증진 이 안되 시공비 상승요인, 문제점이 있기 때문이다. The soil packaging material is used in combination with the calcium carbonate and earth and sand mixture 85 to 75% by weight of MMA resin binder 25 to 15% by weight, which is hardened if the binder is less than 10% by weight of the flooring material Even if it does not appear as a function and exceeds 25% by weight, it is not possible to increase the strength any more, because there is a problem of increase in construction cost.
또한 상기 충진재인 탄산칼슘과 토사는 3:7로 혼합하는 것이 가장 바람직하 나, 이를 제한하는 것은 아니며, 탄산칼슘이 25중량% 미만이거나 토사가 75중량%를 초과하면 공극이 증가하여 물성이 좋지못하므로, 탄산칼슘 25 ∼ 15중량%와 토사 85 ∼ 75중량%의 범위 내에서 적절히 혼합하여 사용하도록 한다. In addition, it is most preferable to mix the filler calcium carbonate and earth and sand to 3: 7, but this is not a limitation. Since it is impossible to use, it is suitably mixed within the range of 25 to 15% by weight of calcium carbonate and 85 to 75% by weight of soil sand.
<실시예> 상기와 같이 되는 흙포장방법은 다음과 같다. 흙 포장의 기초 면인 골재층은 10 ~ 20cm높이로 형성하며 진동 로울러를 이용하여 다짐밀도를 95%이상 되게 기층 면을 형성하며: 형성된 기층면 위에 흙포장재를 혼합, 포설하는 단계로, EXAMPLES The soil packing method as described above is as follows. The aggregate layer, which is the basic surface of the soil pavement, is formed at a height of 10 to 20 cm, and forms a base surface with a compaction density of 95% or more using a vibrating roller: mixing and laying soil packing material on the formed base surface.
재료의 특성상 현장배합을 원칙으로 하며, 이때 모빌믹서를 이용하여 생산하였다.Due to the nature of the material, in principle, on-site compounding is used.
먼저 점질과 사질이 적당히 혼합되어 있는 오염되지 않은 토사 1,700kg에 탄산칼슘320kg을 골고루 혼합한 후 MMA수지 400ℓ에 경화촉진제 100kg을 투입하여 토사에 MMA수지가 골고루 혼합되도록 믹싱 후 기층면 위에 흙포장재를 포설하고 밀대를 이용하여 포장면을 형성해 완성하였다First, mix 320kg of calcium carbonate evenly to 1,700kg of uncontaminated soil, which is a good mixture of slime and sand, and then add 100kg of curing accelerator to 400ℓ of MMA resin. It was laid and the pavement surface was formed using a straw.
상기 흙포장재는 혼합후 곧바로 포설하여야하며 경화 촉진제의 투여량에 따라 경화속도를 조절할수 있다.The soil packaging material should be installed immediately after mixing and can adjust the curing rate according to the dosage of the curing accelerator.
상기와 같이 형성되는 흙포장체는 56.5MPa의 높은 압축강도와 8.6N/㎟의 인장강도로서 기존 시멘트계 흙포장보다 인장강도가 높고 자체 탄성력이 높아 보행시 충격을 흡수하고 균열 발생을 억제할 수 있는 것이다,Soil pavement formed as described above has a high compressive strength of 56.5MPa and a tensile strength of 8.6N / ㎠, higher tensile strength than conventional cement-based soil pavement and its own elastic force is high so that it can absorb shock and prevent cracking when walking. will be,
상기 흙포장층이 완성되면, 12시간의 양생시간을 거쳐 도로를 개방한다.When the soil paving layer is completed, the road is opened through a curing time of 12 hours.
이상에서와 같이 본 발명은 상기한 실시 예에 한하여 설명하였지만 이를 반드시 제한하는 것은 아닌 것으로, 본 발명의 범주와 사상을 벗어나지 않는 범위 내 에서 다양한 변형 실시가 가능함은 물론이다.As described above, the present invention has been described with reference to the above embodiments, but it is not necessarily limited thereto, and various modifications may be made without departing from the scope and spirit of the present invention.
