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
The present invention relates to the method that hardening of ground and stabilizing are built, more specifically relating to be that for example the ground of normal soil ground, not solid (frail) and the feature of sanitary waste or industrial waste ground are come the hardening of ground of firm ground and the method that stabilizing is built to various grounds according to the ground feature.
Background technology
Be surrounded by sea on three sides and Korea peninsula that area is little in should manage ground well.Therefore, press for and effectively utilize soil or have sanitary waste or the soil of industrial waste ground with seashore and landlocked base frailly.
Because local feature, climatic condition, soil property etc., ground have different the composition.In the ground unsound ground be can not support upper building state ground and be the ground of usually forming by the fine-grained soil of unsound clay, silt etc., organic soil etc., and owing to compressibilty and ramuscule load show unsettled machine performance greatly, when on ground, filling or excavating soil operation, setting of ground and destruction can be produced, therefore effective construction method need be set up.
In addition, sanitary waste or industrial waste ground are to be mixed with the sanitary waste that stays after people use or the ground of industrial waste.
On the other hand, foundation improvement material or the allow hardening material that is used for changing unsound ground or sanitary waste or industrial waste ground etc. is divided into two classes according to its purposes.The first kind is to be used for stablizing unsound ground for example highest organic soil earth and the hardening material with soil of high moisture content, and second class is come the hardening material of stabilizing for polluting the industrial waste that causes by sclerosis by air pollution and water.
As the stabilizing material (hardening material) of base frailly that uses in the locality, normally used is the hardening material of cement based.In the U.S., in the thirties in 20th century, as soil quality stabilizing material, the soil cement that soil and ordinary Portland cement mix begins to use with the roadbed material, as the soil stabilization material, but it is at highest organic soil earth, clay with to have in the soil of high-moisture effect relatively poor and uneconomical.Have a lot of Japan of base frailly, in the sixties in 20th century, developed lime base soil quality stabilizing material independently, but its shortcoming is for example hyperhydrated heat, processing hazardous substances, generation dust when building, and in the seventies in 20th century, developed the soil quality stabilizing material (hardening material of cement based) of cement based, used so far always, and exploitation constantly is used for the various improved hardening material of stable soil quality.
Use big water gaging as water of hydration (coupling water) and carry out gypsum and pozzolanic reaction in order to help to generate entringite, the cement based hardening material is designed, makes up and join in slag, coal ash, jet cement or the high alumina cement to improve hardening capacity, perhaps according to purposes jet cement or special cement is joined wherein to adjust their component.But, use the cement based hardening material that uses recently also to be restricted according to area, environment and geographical conditions.In the landfill of sanitary waste and industrial waste, do not take into full account the environmental effect that depends on the percolate component.
In addition, for fixing heavy metal ion, the hardening material utilization is for example adsorbed and the generation of the compound of solid dissolving, weak solubility and the fixing mechanism of replacement of heavy metal in the environment-industry.Therefore, use for example for example gypsum, slag, coal ash of quicklime or hydrated lime, calcium sulphoaluminate base (CSA) material that is used to generate entringite and secondary material of lime base material.
Unsound ground distributes wideless in China.But recently because the expansion of process of industrialization, population increase and economic scale needs comprehensive ground exploitation.Need to develop soil quality stabilizing material inevitably, needing to be used for the relative poverty area of wasteland reclamation and to be used in the mud sclerosis of water supply and draining and draining terminal processes and State owned land exploitation for example because the construction on maritime state's reclaiming land around sea engineering that is surrounded by sea on three sides and new airport as the environmental friendliness cause.
But above-mentioned conventional soil quality stabilizing material seldom is a waterproof, and does not have structural stability owing to the bad mixing of soil particle, and because there is frostbite in the winter time in temperature effect, so it has little defective.
In addition, at base stabilization construction firm ground in the road construction for example, implement to build by using the natural aggregate of gathering (aggregate).Owing to use this to gather materials water is infiltered the ground from the outside, thus the foundation strength deterioration and therefore ground become not solid, the ground durability is worsened and because the collection natural aggregate damages the problem of natural landscape so exist.
In addition,, construction material ships the problem that then exists construction cost to increase from afar if for example gathering materials.
Therefore, the inventor develops the method for a kind of hardening of ground and stabilizing construction, this method can be used for sanitary waste and industrial waste ground and unsound ground, and received Korea patent registration No.24031, exercise question is " a ground hardening and s tabilizingconstruction method (submission on December 29th, 1984) ".The method that a kind of hardening of ground of using powder composition and stabilizing are built is disclosed in patent registration No. 24031, this powder composition by with 14～16% silica (SiO) of cement mixing, 5～6% iron oxide (Fe
2O
2) (steel oxide), 51～53% calcium oxide (CaO), 10～11% alumina (AL
2O
3), 5～6% sulfuric acid (H
2SO
4), 5～6% magnesia (MgO), form with 1.0～1.6% lignosulfonates (lignin sulphonate), as clay, sand, earth, the reinforcer of organic soil, this method is included in the soil stabilization composition of 3～5% (based on cement weights) and cement mixing and regulates after the soil moisture content, mix, push and the pending soil that hardens, wherein in described soil stabilization composition, also add 0.5～1.2% stearate (stearicate), 0.4～1.1% NaOH (NaOH), 1.1～2.4% silica (SiO
2) and tripolyphosphate.
In Korea patent registration No.24031, provide a kind of can be by sclerosis firm ground composition and by using said composition can make base stabilization.But, need come firm ground according to the feature of various grounds, promptly by being that the content that the feature of normal soil ground, unsound ground or sanitary waste or industrial waste ground etc. is regulated above-mentioned composition is applied to the various soil textures according to various grounds.
