Solidified crushing sorting mixing device and manufacturing method thereof and method for constructing order layer using manufactured solidified soils {TH CRUSING AND SOLTING MIXER OF SOILD SOIL AND THE MANUFACTURING METHOD THEREOF AND A CONSTRUCTION METHOD USING SOILD SOIL}

The present invention relates to a solidified soil crushing mixing apparatus, a method for manufacturing the same, and a method for constructing the order layer using the manufactured solidified soil, and more specifically, a field soil input unit into which the soil soil is introduced, and a crushed soil to be crushed. And the fractionation section for sorting the crushed field soil according to the particle size, the solidification input section for inputting MCG solidified material, the raw material storage section for temporarily storing and discharging the inputted raw material, and the ratio of the soil and solidified material It consists of a solidified soil crushing mixing device consisting of a controller unit for controlling the constant metering, a stirring unit for stirring the sorted soil and the solidified fire, and a discharge portion for discharging the mixed solidified soil, the solidified soil crushing sorting mixing The method for producing solidified soil produced by the apparatus is to prepare solidified soil by uniformly agitating the sorted soil, which is crushed by a predetermined particle size, and then crushed after the input of field soil.

In addition, in the order layer construction method using the solidified soil generated by the solidified soil crushing mixing apparatus according to the present invention, an inclined surface which is integrally connected to the bottom surface and the bottom surface in the base of the waste landfill is formed, and the soil is MCG. After the solidified soil is mixed with the solidified fire to form solidified soil, the solidified soil is formed by forming a solidified soil order layer in which the resulting solidified soil is laid on the ground and inclined surface of the ground soil at a predetermined thickness and laminated to form a compacted layer two or more times. By uniform mixing of the hardened soil to improve the ordering ability of the ordered layer significantly.

Recently, with increasing interest in environmental pollution, waste disposal has become a big social problem as one of the measures to prevent environmental pollution related to waste disposal, which accounts for a large proportion of the causes of environmental pollution.

For example, when wastes were thrown away, they could be handled by natural self-cleaning long ago, so the problem of waste did not emerge as a serious social problem. It has emerged as a social problem that has a close influence on life.

Various methods such as recycling, incineration, and landfill are commonly used as treatment methods to treat such wastes.In the case of incineration, air pollution is caused by dust generated during incineration. Processing is main. However, most of the landfills installed so far are buried in an unsanitary landfill system using a simple dumping method without an environmental pollution reduction facility for leachate, odor, etc., which causes severe environmental pollution such as groundwater around the landfill.

In order to prevent this, conventionally, the landfill is used as a bottom solidification material after proceeding the dig in the upper and lower strait type, in which case dry shrinkage cracks or construction joint cracks occur due to the landfill waste load. The contaminated leachate generated by the corrosion and rain of the landfilled waste through the cracks has been leaked to the outside from the landfill has a problem of contaminating groundwater and soil.

In the case of forming a layer using high density polyethylene (HDPE) liner, ie, polyethylene sheet lining, and a solidified soil treated with Soil mortar or Soil cement, which has a suitable thickness of clay or bentonite and other additives in its lower layer. Due to the installation of clays with very high strength as the lower support layer of the polyethylene liner, there are great restrictions on the topography, soil and natural environment of the landfill site. Most of the new landfill sites in Korea Due to the limitation, most of them are located in coastal or inland soft ground or mountainous areas, and because of poor soil and soil properties, there is not enough support of the lower clay layer, resulting in floating settlement and breakage of joints between polyethylene sheets. Construction equipment during or after construction Leachate is the seat itself also damaged by the spill occurred at the landfill had problems going to soak into the underground by.

In addition, when the degree of mixing of the solidified soil forming the ordered layer is not constant and the ordered layer is sub-worked or when the ordered layer is formed in a state in which different solidified soil materials are not sufficiently mixed, the solidified soil which is the solidified material is unbalanced. As a result of the mixing, cracks are generated and the strength is lowered, causing problems such as cracks in the order layer.

An object of the present invention to improve this is to delay the movement of harmful substances to the surrounding environment for a period of time predicted by the thickness and permeation rate of the layer, to prevent the occurrence of cracks by sufficiently mixing different solidified soil materials, This is to prevent cracks from occurring and the strength decreases.
