본 발명은 연약지반 처리용 교반토의 제조시스템에 관한 것으로, 상세하게는 저장조에서 각각 보관 중인 황토, MgO, 장석, 염화칼슘, 염화나트륨, 염화코발트, 규산, 황산나트륨, 매립지 현장토양 등의 재료들을 계량호퍼와 이송컨베이어를 통 해 분쇄기로 공급하고, 분쇄기에서 모래 정도의 크기로 분쇄된 재료들은 교반기에서 잘 혼합한 후 저장탱크에 저장하였다가 현장에서 투명성 방수액과 물을 혼합하면서 시공하도록 함으로써 연약한 지반을 콘크리트로 타설한 것과 같은 강도를 갖도록 하는 동시에 방수의 효과도 얻도록 한 연약지반 처리용 교반토의 제조시스템에 관한 것이다.The present invention relates to a manufacturing system of agitated soil for soft ground treatment, and more specifically, materials such as loess, MgO, feldspar, calcium chloride, sodium chloride, cobalt chloride, silicic acid, sodium sulfate, landfill site soil, etc., respectively stored in a storage tank. The ground material is fed to the grinder through the transfer conveyor, and the ground material is mixed in the stirrer and mixed in the stirrer and stored in the storage tank. The present invention relates to a manufacturing system of agitated soil for soft ground treatment, which has the same strength as that of pour and at the same time obtains the effect of waterproofing.

일반적으로 사람의 주거환경이나 생활환경에는 많은 종류의 지형들이 존재하게 되고, 그 중에는 자연적으로 조성된 연약한 지반도 일부 있지만, 대개는 쓰레기나 각종 폐기물을 임의 매립하는 과정에서 다른 지반보다 상대적으로 연약한 지반이 존재하게 된다.In general, there are many kinds of topography in human living and living environment, some of which are naturally formed soft ground, but most of them are relatively soft ground than other grounds in the process of random landfill of garbage or various wastes. Will exist.

더구나 생활쓰레기 및 산업폐기물을 매립할 때 매립지의 지반에 아무런 시공처리를 하지 않고 매립하여 그 생활쓰레기와 각종의 산업폐기물에서 발생하는 침출수가 매립토양을 오염시키며, 더 나아가서 그 매립지의 지하수를 오염시켜 자연환경을 파괴한다.Moreover, when landfills of industrial wastes and industrial wastes are reclaimed without any construction treatment on the ground of the landfills, the leachate generated from the household wastes and various industrial wastes contaminates the landfill soil and further contaminates the groundwater of the landfills. Destroy the natural environment.

종래에는 생활쓰레기 및 산업폐기물을 매립할 때 매립지의 토양(표토)에 아무런 처리없이 임의로 매립하거나 또는 비닐시트라이닝공법(폴리에틸렌시트라이닝)과 어스라이닝공법(저점도, 벤토나이트)에 의해 그 매립지를 처리한 후 매립하였으나 이들의 공법은 치수방지시공에 있어서 여러 가지의 문제점이 발생하였으며 과도한 시설경비를 필요로 하였다.Conventionally, when landfills of household waste and industrial wastes are landfilled, they are landfilled randomly without any treatment or treated with vinyl sheet lining (polyethylene sheet lining) and earth lining (low viscosity, bentonite). After the landfilling, the construction of these methods caused various problems in the prevention of pulp construction and required excessive facility expenses.

또, 연약지반에 토목공사를 할 때 중장비가 투입되어야 하는데 중장비의 침하로 공사를 할 수 없으므로 다량의 흙 및 돌을 이용하여 복토를 하여야 하는 문제 점이 있어 과도한 공사비를 지출해야하는 문제점이 있었다.In addition, when the civil engineering works on the soft ground, heavy equipment should be put in, but because the construction can not be done due to the sinking of heavy equipment, there is a problem to cover the soil using a large amount of soil and stone, there was a problem to spend excessive construction costs.

그 비닐시트라이닝공법과 어스라이닝공법은 일반적으로 실용화되고 있으나 정밀시공에 문제가 있었다.The vinyl sheet lining method and the earth lining method are generally used, but there is a problem in precision construction.

해안매립지 등 갯벌과 같은 연약지반에서는 시공할 수 없음은 물론, 시공 후에는 그 생활쓰레기와 각종 산업폐기물 등 매립물의 하중에 견디지 못하여 그 시트가 파손되는 경향이 있으며, 특히 그 매립물에 포함한 각종의 파손된 병, 뾰족한 금속파편, 예리한 석재파편 등이 그 시트에 가하여져 구멍을 형성하며, 각종폐기물의 부패에 의해 발생되는 유해물(독극물)은 그 시트에 손상을 주어 현실적으로 문제가 있었다.Not only can not be installed in soft ground such as coastal landfills, but also after the construction, the sheet is not able to withstand the load of landfills such as household waste and various industrial wastes, and the sheet tends to be damaged. Broken bottles, pointed metal debris, sharp stone debris, etc. are applied to the sheet to form holes, and harmful substances (poisons) caused by the decay of various wastes are damaged in the sheet, which is a practical problem.

또, 그 어스라이닝공법은 매립지의 법면과 바닥면에 침출수의 유출이 발생하는데 투수계수 10-7cm/sec 이상을 가진 점토입자의 접착에는 문제가 있어 사용할 수 없었다.In addition, the earth lining method has a problem of adhesion of clay particles having a permeability coefficient of 10 −7 cm / sec or more due to the outflow of leachate from the surface and the bottom surface of a landfill.

더 나아가 연약지반주입혼합공법(한국특허공고 제92-4021호)에서는 각 매립지의 현장토양을 고화시킬 수 있는 있으나, 그 생활쓰레기 및 산업폐기물을 매립할 때 발생하는 우수와 중금속함유침출수는, 완전한 방수 콘크리트화가 형성되지 않고 고화만 되어 발생한 균열내에 투수되어 지하수의 매립토양을 오염시키는 결점이 있었다.Furthermore, the soft ground injection mixing method (Korean Patent Publication No. 92-4021) can solidify the site soil of each landfill site, but the runoff and heavy metal-containing leachate generated when landfilling the household waste and industrial wastes are There was a drawback of contaminating the landfill soil of groundwater due to the permeation of cracks caused by solidification without forming waterproof concrete.

즉, 시험결과 그 고화된 토양은 투수계수 10-7cm/sec 이상으로 얻지 못하여 그 고화토양을 통하여 그 지하수나 토양을 그 침출수가 오염시켰다.That is, as a result of the test, the solidified soil did not get more than 10 -7 cm / sec permeability and contaminated the groundwater or soil through the solidified soil.

환경부에서 시행하는 환경법규정에 미달되어 침출수를 방지할 수 없었다.The leachate could not be prevented because it failed to meet the environmental legislation enforced by the Ministry of Environment.

따라서, 위 인용한 특허의 주입혼합공법은 사용할 수 없으며 고화기간 7일을 필요로 하는 결점이 있었다.Therefore, the injection-mixing method of the above-cited patent cannot be used and has a drawback requiring 7 days of solidification period.

이에 본 발명은 상기한 바와 같은 종래의 문제점을 해소시키기 위하여 안출된 것으로, 저장조에서 각각 보관 중인 황토, MgO, 장석, 염화칼슘, 염화나트륨, 염화코발트, 규산, 황산나트륨, 매립지 현장토양 등의 재료들을 계량 호퍼와 이송컨베이어를 통해 분쇄기로 공급하고, 분쇄기에서 모래 정도의 크기로 분쇄된 재료들은 교반기에서 잘 혼합한 후 저장탱크에 저장하였다가 현장에서 투명성 방수액과 물을 혼합하면서 시공하도록 함으로써 연약한 지반을 콘크리트로 타설한 것과 같은 강도를 갖도록 하는 동시에 방수의 효과도 얻도록 한 연약지반 처리용 교반토의 제조시스템을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been made in order to solve the conventional problems as described above, hopper for weighing materials such as ocher, MgO, feldspar, calcium chloride, sodium chloride, cobalt chloride, silicic acid, sodium sulfate, landfill field soil, etc. respectively stored in the storage tank The ground material is fed to the grinder through the feed conveyor, and the ground material of the sand size is mixed well in the stirrer and stored in the storage tank.

The ingredients are mixed well and mixed well to form a stirred soil.

상기의 교반기(27)에서 잘 혼합된 교반토는 제6 이송컨베이어(28)를 통해 현장의 저장탱크(29)에 저장하였다가 현장에서 투명성 방수액 2～5중량%과 물 2～3중량%를 혼합하면서 시공하도록 한다.Stirred soil mixed well in the stirrer 27 is stored in the storage tank 29 of the site through the sixth conveying conveyor 28, and 2 to 5% by weight of the transparent waterproofing solution and 2 to 3% by weight of water at the site. Apply while mixing.

상기의 시공에 의하여 토양 중에 서식하는 바이러스 파스터리와 스포로사르 시나라는 두 종의 박테리아가 장석의 간극에 충전되어 일반 시멘트와는 다른 방법에 의해 토양 콘크리트화 된다.According to the above-mentioned construction, two kinds of bacteria, ie, virus pastory and sporosarcine, inhabit the soil, are filled in the feldspar gap, and the soil is concreted by a method different from ordinary cement.

또 본 발명의 교반토에 투명성 방수액과 물을 혼합하면서 제조한 토양 콘크리트화 개량토의 특성상 물에 대한 흡착능력과 배출능력을 갖고 있으며, 이온교환 능력을 가진 토양콘크리트의 역할을 한다.In addition, due to the characteristics of the soil-concrete improved soil prepared by mixing the transparent waterproofing liquid and water in the stirred soil of the present invention has the adsorption capacity and discharge capacity for water, and serves as a soil concrete with ion exchange capacity.

또, 매립지의 지반이 연약하여도 강한 콘크리트의 지지력에 의해 균등하게 침하하기 때문에 전체적으로 안전된 상태를 유지하게 되고, 이는 본 발명에 의한 개량토가 탄력성을 갖고 있기 때문이다.In addition, even if the ground of the landfill is soft, it is settled evenly by the support force of the strong concrete, so that the overall safe state is maintained, because the improved soil according to the present invention has elasticity.

어느 정도 비가 내리는 환경에서도 시공할 수 있으며 흙 암벽을 형성하므로 반영구적으로 안전하다.It can be installed even in a rainy environment and it is semi-permanently safe because it forms soil rock walls.

그리고 수중에 투하하여 콘크리트화 하여도 유화제 역할은 물론, 황토와 장석 등의 급속한 응결반응을 진행시켜 폐기물 및 갯벌과 같이 염분이 함유된 해안토양이라도 시험결과 수 시간 내에 고결시켜 시간이 흐르면 콘크리트화 된다.Also, even if it is dropped into water and concrete, it acts not only as an emulsifier but also rapidly condensation reactions such as ocher and feldspar to solidify in coastal soils containing wastes and tidal flats within a few hours. .

본 발명의 장치에 의한 지반은 황토와 장석의 성질로 인해 모래와 자갈 및 시멘트에 의한 콘크리트의 수명보다 장기간에 걸쳐 지지력을 안정시키고 무공해물질로 2차적인 공해의 염려가 없게 된다.The ground by the device of the present invention stabilizes the bearing capacity for a longer time than the life of concrete by sand, gravel and cement due to the nature of loess and feldspar, and there is no fear of secondary pollution as pollution-free material.

본 발명의 토양콘크리트화 개량토에 포함된 각 원소와 광물질성분은 이온화하여 활발하게 활동을 한다.Each element and mineral component contained in the soil concrete improved soil of the present invention is active by ionizing.

이와 같은 상호 작용에 의해 토양의 입자 상호간의 간격이 좁아지고 전위 저하와 함께 토양입자의 고결화가 되어 칼슘이온의 침입을 방해하는 토양입자간의 미 세한 입자가 연결된다.This interaction narrows the spacing between the soil particles, lowers the potential, and solidifies the soil particles, thereby connecting the fine particles between the soil particles that prevent the invasion of calcium ions.

이상에서 상세히 설명한 바와 같이 본 발명에 따른 연약지반 처리용 교반토의 제조시스템에 의하여서는 저장조에서 각각 보관 중인 황토, MgO, 장석, 염화칼슘, 염화나트륨, 염화코발트, 규산, 황산나트륨, 매립지 현장토양 등의 재료들을 계량 호퍼와 이송컨베이어를 통해 분쇄기로 공급하도록 하고,As described in detail above, according to the present invention, a system for preparing agitated soil for soft ground treatment includes materials such as ocher, MgO, feldspar, calcium chloride, sodium chloride, cobalt chloride, silicic acid, sodium sulfate, and landfill soil in storage tanks, respectively.
