Problems solved by technology

Since water infiltrates into the foundation from the outside using this aggregate, the strength of the foundation is deteriorated and thus the foundation becomes weak, so there are problems of deteriorating the durability of the foundation and damaging the natural scenery due to collection of natural aggregates
[0012] In addition, if construction materials such as aggregates are transported from a distance, there is a problem that construction costs increase

Embodiment approach

[0053] The soil and sand used here are clay sand (SP-SM) in which silt is mixed, and the soil mixed with cloth, vinyl, plastic, etc. is used in domestic waste as garbage.

[0054] The tests on soil and sand are shown in Table 1.

[0055] Table 1

[0056] test

[0057] A sample with a three-layer structure was prepared by the following process: domestic waste soil was mixed with soil and sand and foundation hardener (GH agent), and each layer was pressed 25 times with a pressure hammer with a weight of 5 Kg and a height of 30°, and then subjected to Natural dry hardening (temperature of 20±2° C.), wherein the domestic waste soil was reformed with soil and sand and foundation hardener and mixed with an optimum moisture content of 13.3% passing the extrusion test A of Table 1.

[0058] As shown in Figure 5, the domestic waste foundation for foundation hardening and stabilization construction was dug 2m deep and the operation space was divided into three layers (70cm, ...

Abstract

There is provided a ground hardening and stabilizing construction method. The ground hardening and stabilizing construction method which stabilizes by applying to ground a ground hardener completed by a first process of manufacturing a powder composition by mixing a silicon oxide (SiO), a steel oxide (Fe O ), a calcium oxide (CaO), an aluminum oxide (AL O ), a sulfuric acid (H 2 SO 4 ), a magnesium oxide (MgO), and a lignin sulphonate to cement as a rein- forcement filler for soil of clay, sand, dirt, organic; a second process of manufacturing a mixed soil stabilizing composition by mixing a stearicate, a sodium hydroxide (NaOH), a silica (SiO ), and a tripolyphosphate to the powder composition; a third process of manufacturing a ground hardener (GH agent) by mixing cement to the soil stabilizing composition, the method comprising: applying, mixing, paving, pressing, and cementing to a ground hardener of 1 to 15 wt% to a unit weight of the ground soil, when an object ground to be stabilized is general soil ground.

Description

technical field [0001] The present invention relates to a method of ground hardening and stabilizing construction, and more particularly to ground hardening which can stabilize a ground according to ground characteristics, i.e., characteristics of various grounds such as common soil grounds, frail grounds, and domestic waste or industrial waste grounds and methods of stabilizing builds. Background technique [0002] In the small Korean peninsula surrounded by sea on three sides, the foundation should be well managed. Therefore, there is an urgent need to effectively utilize land with weak foundations on the coast and inland or land with domestic or industrial waste foundations. [0003] Foundations have different compositions due to local characteristics, climatic conditions, soil properties, etc. The weak foundation among the foundations is a foundation in a state that cannot support the superstructure and is a foundation generally composed of fine-grained soil such as cl...
