이 발명은 생활쓰레기 및 산업폐기물 매립지의 지반처리시공법 및 그 지반의 토양고화조성물에 관한 것이다.The present invention relates to a ground treatment method for landfills and industrial waste landfills and to soil solidified compositions of the ground.
생활쓰레기 및 산업폐기물을 매립할때 매립지의 지반에 아무런 시공처리를 하지 않고 매립하며 그 생활쓰레기와 각종의 산업폐기물에서 발생하는 침출수가 매립토양을 오염시키며, 더 나아가서 그 매립지의 지하수를 오염시킨다.When landfills of industrial wastes and industrial wastes are reclaimed without any construction treatment on the ground of landfills, leachate from the household wastes and various industrial wastes contaminates the landfill soil and further contaminates the groundwater of the landfills.
이와같은 오염은 자연환경을 파괴한다.Pollution like this destroys the natural environment.
따라서, 이 발명은 이와같은 오염의 근본적인 원인을 규명하여 효과적인 대책을 연구한 결과 그 침출수의 지하수유입을 차단함과 동시에 토양의 오염을 방지하기 위하여 그 침출수를 일정한 처리장소로 유실됨이 없이 회수처리하도록 그 매립지의 지반을 토양 고화조성물에 의해 효과적으로 처리하여 그 침출수를 완전 방수되게 시공함으로써 이 발명의 목적을 달성할 수 있다.Therefore, the present invention is to investigate the root cause of such pollution and to study effective countermeasures, and in order to block the groundwater inflow of the leachate and to prevent the contamination of the soil, the leachate is recovered without being lost to a certain treatment place. The object of this invention can be achieved by effectively treating the ground of the landfill with a soil solidification composition so that the leachate is completely waterproofed.
종래에는 생활쓰레기 및 산업폐기물을 매립할때 매립지의 토양(표토)에 아무런 처리없이 임의로 매립하거나 또는 비닐시트라이닝공법(폴리에틸렌시트라이닝)과 어스라이닝공법(저점도, 벤토나이트)에 의해 그 매립지를 처리한후 매립하였으나 이들의 공법은 치수방지시공에 있어서 여러가지의 문제점이 발생하였으며 과도한 시설경비를 필요로 하였다.Conventionally, when landfills and industrial waste are buried, they are landfilled at random without any treatment, or the landfill is treated by vinyl sheet lining (polyethylene sheet lining) and earth lining (low viscosity, bentonite). Although they were landfilled, their construction methods caused various problems in the prevention of pulp and required excessive facility expenses.
즉, 그 비닐시트라이닝공법과 어스라이닝공법은 일반적으로 실용화되고 있으나 정밀시공에 문제가 있다. 해안매립지등 갯벌과 같은 연약지반에서는 시공할 수 없음은 물론, 시공후에는 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, 각종 폐기물의 부패에 의해 발생되는 유해물(독극물)은 그 시트에 손상을 주어 현실적으로 문제가 있다.That is, the vinyl sheet lining method and the earth lining method are generally used, but there is a problem in precision construction. Not only can it be installed on soft ground such as coastal landfills, but also after the construction, it can not withstand the load of landfills such as household waste and various industrial wastes, and the sheet tends to be damaged. Broken bottles, sharp 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 10-7㎝/sec 이상을 가진 점토입자의 접착에는 문제가 있어 사용할 수 없다.In addition, the earth lining method causes the outflow of leachate to the surface and the bottom surface of the landfill, but there is a problem in the adhesion of clay particles having a permeability coefficient of 10 −7 cm / sec or more and cannot be used.
더 나아가서, 연약지반주입혼합공법(한국 특허공고번호 92-4021, 1992. 5. 22. 공고)에서는 각 매립지의 현장토양을 고화시킬 수는 있으나, 그 생활쓰레기 및 산업폐기물을 매립할때 발생하는 중금속함유침출수가 그 고화된 매립지에 투수되어 지하수의 매립토양을 오염시키는 결점이 있다.Furthermore, the soft ground injection mixing method (Korean Patent Publication No. 92-4021, May 22, 1992) can solidify the site soil of each landfill, but it can be caused by landfills and industrial wastes. There is a drawback that heavy metal-containing leachate is permeated to the solidified landfill and contaminates the landfill soil of groundwater.
즉, 시험결과 그 고화된 토양은 투수계수 10-7㎝/sec 이상으로 얻지 못하여 그 고화토양을 통하여 그 지하수나 토양을 그 침출수가 오염시킨다.That is, as a result of the test, the solidified soil is not obtained with a permeability coefficient of 10 -7 cm / sec or more, and contaminates the groundwater or soil through the solidified soil.
환경처에서 시행하는 환경법규정에 미달되어 침출수를 방지할 수 없다.Leachate cannot be prevented because it falls short of environmental laws and regulations enforced by the Ministry of Environment.
따라서, 위 인용한 특허의 주입혼합공법은 사용할 수 없으며 고화기간 7일을 필요로 하는 결점이 있다.Therefore, the injection-mixing method of the above-cited patent cannot be used and has a disadvantage of requiring 7 days of solidification period.
따라서, 이 발명은 그 생활쓰레기 및 각종의 산업폐기물을 매립할때 발생하는 여러가지의 문제점을 제거하여, 그 쓰레기 및 폐기물의 매립으로 발생하는 침출수가 그 매립지의 토양과 지하수로 침투되는 것을 완전차단시킴과 동시에 그 침출수를 일정한 회수장소로 모이도록 하여 시공하는 생활쓰레기 및 각종 산업폐기물 매립지의 지반처리시공법을 제공하는데 있다.Therefore, the present invention eliminates various problems that occur when the landfill and various industrial wastes are landfilled, and completely prevents the leachate generated by the landfill of the garbage and wastes from penetrating into the soil and groundwater of the landfill. At the same time, the leachate is collected at a certain collection point to provide ground treatment and construction methods for landfills and industrial waste landfills.
또, 이 발명은 제오라이트, 야자유로 처리한 생선회, 시멘트, 매립지현장토양(산토양,해안토양 등), 토양고화혼합물(염화칼륨,염화칼슘,염화마그네슘,염화나트륨,염화코발트,규산,황산나트륨으로 조성), 투명성 방수액 및 물로 조성시켜, 고화처리에 의해 양생시간을 단축시킴(3일에서 12시간으로 단축)과 동시에 투수계수를 10-7㎝/sec 이상으로 되도록 한 토양고화조성물을 제공하는데 있다.In addition, the present invention is zeolite, sashimi treated with palm oil, cement, landfill soil (mountain soil, coastal soil, etc.), soil solidified mixture (potassium chloride, calcium chloride, magnesium chloride, sodium chloride, cobalt chloride, silicate, sodium sulfate), It is provided with a transparent waterproofing liquid and water to shorten the curing time by solidification treatment (shortening from 3 days to 12 hours) and at the same time to provide a soil solidified composition with a permeability coefficient of 10 −7 cm / sec or more.
이 발명의 목적을 실현시키기 위한 구체적 기술구성을 아래에 설명한다.Specific technical configurations for realizing the object of the present invention will be described below.
정지한 그 매립지의 지반에 처리하는 토양고화조성물에 대하여 아래에 설명한다.The soil solidification composition to be treated in the ground of the suspended landfill is described below.
이 토양고화조성물은 내수성이 우수하고, 산알칼리에 강하다.This soil solidified composition is excellent in water resistance and resistant to acid alkali.
또 집중하중면에서 볼때 강도가 강하고 폐기물중의 어떤 하중 있는 이물질이 있어서도 파손될 염려가 없고, 이 조성물에 의해 얻어진 개량토는 강도가 있으며 그 매립지에서 주로 3층으로 축조되어 있어 침출수의 투수가 발생되지 않는다. 실험결과 투수계수 10-7㎝/sec 이상이다.In terms of concentrated load, the strength is strong and there is no fear of damage in case of any loaded foreign matter in the waste, and the improved soil obtained by this composition has strength and is mainly built in three layers in the landfill, so no leachate permeate occurs. Do not. The experimental result is more than 10 -7 cm / sec permeability coefficient.
또, 이 토양고화조성물에 의해 얻어진 개량토의 특성상 볼때 유해물질의 흡착능력을 갖고 있으며, 이온교환능을 가진 흙 인공암벽을 지닌 제오라이트의 역할을 한다.In addition, due to the characteristics of the improved soil obtained by this soil solidification composition, it has the ability to adsorb harmful substances and acts as a zeolite having an artificial rock wall with ion exchange capacity.
또, 매립지의 지반이 연약하여도 강한 지지력에 의해 균등침하를 하기 때문에 안전하다. 이것은 이 조성물이 탄력성을 갖고 있기 때문이다.Moreover, even if the ground of the landfill is soft, it is safe because it is evenly settled by a strong bearing force. This is because this composition has elasticity.
어느 정도의 비에도 시공할 수 있으며 흙 암벽을 형성하므로 영구적으로 안전하다.It can be installed in any amount of rain and is permanently safe as it forms soil rock walls.
다른 공법(시트라인링공법,어스라이닝공법)에 비하여 시공비가 염가이고 공기를 단축하며 사후관리가 간단하여 경제적이다.Compared with other construction methods (seatlining, earthing), the construction cost is cheaper, the air is shorter, and the follow-up management is simple and economical.
이와같이 토양고화조성물은 실험결과 아래와 같은 조성을 갖는 것이 바람직하다.As such, it is preferable that the soil solidified composition has the following composition.
제오라미트 25wt%, 바람직하게는 11wt%, 야자유처리생석회 2-5wt%, 현지토양(산토양,해안토양 등…) 60wt%, 토양고화혼합물(염화칼륨,염화칼슘,염화마그네슘,염화나트륨,염화코발트,규산,황산나트륨으로 조성) 1-2wt%, 특히 바람직하게는 1wt%, 투명성방수액(시중제품) 1-2wt%, 특히 바람직하게는 1wt%, 물 1-2wt%, 특히 바람직하게는 2wt%으로 조성한다.Zeolite 25wt%, preferably 11wt%, palm oil-treated quicklime 2-5wt%, local soil (mountain soil, coastal soil, etc.) 60wt%, soil solidified mixture (potassium chloride, calcium chloride, magnesium chloride, sodium chloride, cobalt chloride, Composition with silicate and sodium sulfate) 1-2wt%, particularly preferably 1wt%, transparent waterproofing liquid (commercially available) 1-2wt%, particularly preferably 1wt%, water 1-2wt%, particularly preferably 2wt% do.
위와같은 조성은 현지토양의 물성에 따라 조성비를 변화시켜 조성할 수 있다.Such a composition can be formed by changing the composition ratio according to the properties of the local soil.
이와같이 토양고화조성물에 있어서, 제오라이트는 양이온교환흡착능을 갖고 있어 침출수자체를 흡수할 수 있는 양만 흡수하고 나머지는 배척하므로 고화상태에서는 침출수방지에 효과적인 반면 토양고화혼합물과 투명성방수액이 포함되어 있어 제오라이트와 현지토양의 입자표면에 방수피막을 형성한다.Thus, in the soil solidified composition, zeolite has a cation exchange adsorption capacity, so it absorbs only the amount that can absorb the leachate itself and rejects the rest, so it is effective to prevent the leachate in the solidified state, while the soil solidified mixture and the transparent waterproofing liquid are contained, so that the zeolite and the local A waterproof film is formed on the soil surface.
동시에 수중에 회석하면 유화제역할은 물론 시멘트의 급속한 응결반응을 진행시켜 폐기물 및 갯벌과 같이 염분이 함유된 해안토양이라도 시험결과 12시간 내에 고결시킨다.At the same time, if it is immersed in water, it acts as an emulsifier as well as the rapid condensation reaction of cement and solidifies coastal soil containing salts such as waste and tidal flats within 12 hours of test results.
일반적으로 토양은 점토와 모래를 주성분으로하여 토성에 따라 여러가지의 토양형태를 취하고 있는바, 식물등에 의해 토색이 흑갈색으로 되는 것으로, 유기물이 분해하여 생성된 복잡한 고분자혼합물 등이 토양입자 주위의 부착수에 용해되어 이것이 시멘트페이스트 중의 칼슘이온과 반응하여 시멘트수화물 표면에 불유수막을 형성하고 부의 활동을 하기 때문에 잔결정화의 진행을 방해한다.In general, soil is composed mainly of clay and sand, and has various soil types according to the soil. The soil becomes dark brown by plants, and complex polymer mixtures generated by decomposition of organic matter are attached to soil particles. It dissolves in and reacts with the calcium ions in the cement paste to form a non-hydrophobic film on the surface of the cement hydrate and negatively inhibits the progress of after-crystallization.
따라서, 이 발명의 토양고화조성물을 이용함으로써 토양의 대전상태를 제거할 수 있고 이온교환작용을 이용하여 입자간 배열을 정연하게 하며, 시멘트의 점착력을 높이고 입자간결합을 좋게 함으로써 부식토양, 점토질등의 연약지반에서도 지지력이 안정된 지반으로 향상시킬 수 있다.Therefore, by using the soil solidification composition of the present invention, it is possible to remove the state of charge of the soil, and to make the arrangement of particles by using ion exchange effect, to increase the adhesion of cement and to improve the interparticle bonding, and so on the soil, clay quality, In soft ground, the bearing capacity can be improved to a stable ground.
이 발명의 퍼이에 의한 지반은 시멘트의 성질을 이어받아 수경상태로 장기간에 걸쳐 지지력을 안정시키고 무공해물질로 2차적인 공해의 염려가 없다.The ground by the pui of the present invention inherits the properties of cement to stabilize the bearing capacity for a long time in a hydroponic state, and there is no fear of secondary pollution as a pollution-free material.
이 발명의 토양고화조성물은 소일시멘트등의 결점인 강도부족, 칼슘이온의 용출등에 의한 2차공해와 노화에 의한 결점을 제거한다.The soil solidification composition of the present invention eliminates defects due to secondary pollution and aging due to lack of strength, elution of calcium ions, and the like.
이 토양고화조성물에 포함된 각 원소는 이온화하여 활발하게 활동을 한다.Each element in this soil solidification composition ionizes and is active.
토양주에는 고분자화합물의 유기물이 물에 용해한 형태로 다량함유되어 있어 토양입자를 중심으로하여 그 부근에 이온군을 형성함으로써 칼슘이온의 침입을 저해하는 이온과 반응하여 불유수막을 형성하고 있는 R-COOH를 함유한 흡착수를 가짐과 동시에 토양입자 주변의 물분자도 이온군 밖으로 염출하는 효과를 나타낸다.Soil liquor contains a large amount of organic compounds in the form of dissolved in water, and forms a group of ions around the soil particles and reacts with ions that inhibit the invasion of calcium ions, forming an oil-free film. In addition to having adsorbed water containing COOH, water molecules around soil particles also have the effect of salting out of the ion group.
이와같은 메카니 에 의해 토양입자상호간의 간격이 좁아지고 전위 저하와 함께 토양입자의 고결화가 되어 칼슘이온의 침입을 방해하는 토양입자간의 미세한 입자가 연결됨으로써 단립화(aggregation)가 형성된다.This mechanism narrows the spacing between the soil particles, decreases the potential, causes the soil particles to solidify, and connects the fine particles between the soil particles that prevent the intrusion of calcium ions.
또, 알칼리액상을 형성하여 시멘트의 수화반응인 칼슘실리카 등의 수화물이 토양입자사이의 중간역할이 되는 반상결정을 형성하여 급속성장을 한다.In addition, by forming an alkaline liquid phase, a hydrate such as calcium silica, which is a hydration reaction of cement, forms a half-phase crystal that becomes an intermediate role between soil particles, thereby rapidly growing.
즉, 시멘트페이스트의 유동성은 소실하여 응결반응이 진행됨으로써 토양구조물에 요구되는 전단강도 변형에 대한 저항내수성이 현저하게 향상된다.That is, the fluidity of the cement paste is lost and the condensation reaction proceeds, thereby significantly improving the resistance to shear strength deformation required for the soil structure.
이와같이 구성된 토양고화조성물은 아래와 같이하여 제조된다.The soil solidification composition thus constructed is manufactured as follows.
물탱크에 필요량의 물을 주입하고 소정의 토양고화혼합물을 혼합시킨 다음 투명성 방수액(소요량)을 넣고 혼합한다. 얻어진 혼합액을 액상분사장치로 사전에 혼합한 시료(현지토양+제오라이트+시멘트+야자유처리 생석회) 1㎥에 분사하면서 레미콘 등의 혼합장치로 혼합 및 교반하여 토양고화조성물을 얻는다.Inject the required amount of water into the water tank, mix the predetermined soil solid mixture, and add the transparent waterproofing liquid (required amount). The obtained liquid mixture is sprayed onto 1 m 3 of a sample (local soil + zeolite + cement + palm oil-treated quicklime) mixed with a liquid spraying device, mixed and stirred with a mixing device such as ready-mixed concrete to obtain a soil solidified composition.
시공하고저 하는 매립지의 바닥과 법면에 그 얻어진 토양고화조성물을 부어 롤러로 다짐하여 시공을 한다.Pour the obtained soil solidified composition on the bottom and the surface of the landfill to be constructed and compact it with a roller.
이 발명에 의한 시공방법을 도면에 따라 아래에 설명한다.The construction method by this invention is demonstrated below according to drawing.
이 발명에 의해 얻어진 토양고화조성물을 사용하여 선정한 매립지를 정지한 다음 그 매립지에 제1도에서와 같이, 법면(法面)(11)과 저반(低盤)(10)을 구성시켜 3층으로 축조시킨다. 그 3층은 제1층, 제2층 및 제3층으로 되어 있다.The landfill site selected using the soil solidification composition obtained in this invention is stopped, and then, as shown in Fig. 1, the surface 11 and the bottom 10 are formed into three layers. Construct. The three layers consist of a first layer, a second layer and a third layer.
제1층의 보조기층(12,12')은 지반을 토양고화조성물로 고화시킨 것으로 압축강도 5㎏/㎠ 이상, 투수계수 10-7㎝/sec 이상이 되도록 시공하여 고화양생하며 층두께는 0.3-0.4m가 바람직하다.The auxiliary base layer (12, 12 ') of the first layer solidifies the ground with the soil solidification composition, and it is constructed to have a compressive strength of at least 5㎏ / ㎠ and a permeability coefficient of at least 10 -7 ㎝ / sec, and the layer thickness is 0.3. -0.4 m is preferred.
제2층의 동결방지층(13,13')은 시공한 보조기층(12,12')이 고화양생된 다음에 그 보조기층상면에 그 토양고화조성물을 사용하여 고화시킨 것으로 압축강도 10㎏/㎠ 이상, 투수계수 10-7㎝/sec 이상이 되게 시공하여 고화양생한다.The freeze protection layer (13, 13 ') of the second layer is the solidified state of the auxiliary base layer (12, 12'), and then solidified using the soil solidification composition on the upper base layer. As mentioned above, it is hardened by constructing it so that permeability coefficient may be more than 10-7 cm / sec.
층두께 0.2-0.3m가 바람직하다.The layer thickness is preferably 0.2-0.3 m.
제3층의 침출수방지방수층(14,14')은 생활쓰레기나 각종 산업폐기물이 접촉되는 접촉층으로 그 생활쓰레기나 그 폐기물로부터 발생하는 침출수를 완전 방수하는 층(layer)이다. 이 침출수방지방수층(14,14')은 제2층의 동결방지층(13,13')이 고화양생된 다음 시공을 하며, 고화양생을 시킬경우 압축강도 30㎏/㎠ 이상, 투수계수 10-10㎝/sec 이상이 되도록 한다.The leachate prevention waterproofing layers 14 and 14 'of the third layer are layers for contacting household waste and various industrial wastes and are layers that completely leach the leachate generated from the household waste or its wastes. The leachate waterproofing layer (14,14 ') is constructed after the freezing prevention layer (13,13') of the second layer is hardened and cured, and when hardened, the compressive strength is more than 30㎏ / ㎠ and permeability coefficient is 10 -10. It should be more than cm / sec.
또, 매립지가 연약지반을 가질경우, 제2도에서와 같이 그 지반에 대한 매립하중으로 균열이 발생할 우려가 있어 이를 방지하기 위하여 저반을 균열방지용기둥(15) 형상으로 시공시켜 고화양생한다.In addition, when the landfill has a soft ground, there is a risk of cracking due to the landfill load on the ground, as shown in Figure 2 in order to prevent the construction of the bottom plate in the shape of a pillar for preventing cracks 15 to solidify.
더 나아가서, 제3도 및 제4도에서와 같이 그 생활쓰레기와 각종 폐기물에서 발생하는 침출수를 효과적으로 한곳으로 집수처리하기 위하여 제3층의 침출수방지방수층(14)을 일정한 경사도 θ로 경사지게 시공하며 또 침출수를 한곳으로 집수처리시켜 회수하는 골(단면이 반원형상)(침출수유입로)(a)을 하나이상 다수 구성시킨다. 그 침출수는 그 골(a)을 통해 집수하는 반원형요홈(16)을 제3층의 법면과 저반의 접속부분에 형성한다.Furthermore, in order to collect and treat the leachate generated from the household waste and various wastes into one place as shown in FIGS. 3 and 4, the leachate prevention layer 14 of the third layer is inclined at a constant inclination θ and One or more bones (cross section is semicircular) (leakage inflow path) (a) for collecting and collecting the leachate in one place are constructed. The leachate forms semicircular grooves 16, which are collected through the valleys a, at the connecting surface of the bottom surface and the bottom of the third layer.
여기서 경사도 θ는 5% 정도가 바람직하며, 그 요홈(16)을 중심으로 하여 방사상의 다수의 골(부채의 부채살형상)을 형성하는 것이 바람직하다.In this case, the inclination θ is preferably about 5%, and it is preferable to form a large number of radial valleys (debt-shape of the fan) around the groove 16.
이 반원형요홈(6)에 회수된 침출수는 별도의 처리수단에 의해 처리한다.The leachate collected in the semicircular groove 6 is treated by separate treatment means.
이 골(a)은 제3층의 침출수방지방수층(14)만이 아니라 그 법면(14')에도 동일하게 시공할 수도 있다.This valley (a) can be similarly applied not only to the leachate waterproofing layer 14 of the 3rd layer but also to the surface 14 '.
시공처리하여 고화양생한 제1층 내지 제3층의 전체두께는 06-1.0m가 바람직하다. 따라서, 이 발명에 의해 효과적으로 처리되는 시공순서는 다음과 같다.As for the total thickness of the 1st-3rd layer solidified by the construction process, 06-1.0m is preferable. Therefore, the construction procedure effectively processed by this invention is as follows.

a) 토양고화조성물 제조(해안지대)a) Preparation of Soil Solidified Composition (Coastal Zone)
물탱크(water tank)에 물 20ℓ를 주입하고 토양고화혼합물 1㎘를 혼합시킨다음 투명성방수액(시중제품) 1㎘를 혼합시켰다. 액상분사장치를 사용하여 사전에 혼합한 토양혼합(해안토양+제오라이트+시멘트+야자유처리 생석회) 1㎥에 위에서 얻어진 혼합물(물+토양고화혼합물+투명성방수액)을 분사시키고 레미콘으로 혼합, 교반하였다.20 liters of water was injected into a water tank and 1 cc of soil solidified mixture was mixed, followed by mixing 1 cc of a transparent waterproofing liquid (commercially available). 1 m 3 of the soil mixture (coastal soil + zeolite + cement + palm oil-treated quicklime) mixed with a liquid spraying device was sprayed, and then mixed with a ready-mixed concrete and agitated.
이와같이 하여 토양고화조성물을 얻었다.In this way, a soil solidified composition was obtained.
b) 매립지의 시공(해안지대)b) Construction of landfills (shore zones)
매립지는 해안지대(토양수분함량 20%까지 건조)를 선정하였다.Landfill sites were selected for coastal land (drying up to 20% soil moisture content).
제1층의 보조기층(12,12') 두께 0.3m, 제2층의 동결방지층(13,13') 두께 0.3m, 제3층의 침출수방지방수층(14,14') 두께 0.1m로 구성하여 전체두께 1m가 되도록 위 토양고화조성물을 사용하여 제1도의 시공순서 ①∼⑥에서와 같이 시공공정을 밟아 시공하였다.0.3m thick auxiliary base layer 12, 12 'of first layer, 0.3m thick layer of freeze protection layer 13,13' of second layer, 0.1m thick leachate-resistant waterproof layer 14, 14 'of third layer Using the above-mentioned soil solidified composition so that the total thickness is 1m, the construction process was carried out as in the construction procedure ① to ⑥ of FIG.
이때, 제3층의 침출수방지방수층(14)의 경사를 5%로 되게 경사시공하였으며 침출수유입로(골)(단면은 반원형상)(a)를 방사상으로 구성하고 한곳으로 접수시킨 반원형요홈(16)을 구성하였다. 또 매립지의 현장을 조사한 결과, 지반이 연약하여 제2도에서와 같이 균열방지용기둥(15)을 형성시켜 시공하였다.At this time, the slope of the leachate preventing waterproof layer 14 of the third layer was inclined to 5%, and the leachate inflow path (a bone) (section is semicircular) (a) was formed radially and received in one place. ). In addition, as a result of investigating the site of the landfill, the ground was soft, and thus the crack prevention column 15 was formed and constructed as shown in FIG.
층위별 압축강도 및 투수계수는 실험결과(공시방법) 아래와 같다.Compressive strength and permeability coefficient for each layer are as follows.
제1층(12,12') : 압축강도 15㎏/㎠1st layer (12,12 '): Compressive strength 15㎏ / ㎠
