(configuration example of earth auger)
Hereinafter, illustrating the outline structure example of the earth auger involved by present embodiment referring to Fig.1.Involved by present embodiment
And earth auger 5 be connected on the work car such as trailer and use.More specifically, as shown in Figure 1, in work cars such as trailers
The one end for the guide rod 2 that the front end connection of swing arm 1 extends in vertical direction.Also, the another side of the guide rod 2 is uprightly arranged
In ground exterior portion 3.It is movably equipped with the rotary unit 4 with speed reducer in the upper side of guide rod 2, it is rotatable in the rotary unit 4
Ground is vertically installed with earth auger 5.Earth auger 5 has canister portion 6 and is set to the excavation of the spiral screw-like of the periphery of the canister portion 6
The wing 7.Also, it is equipped with sharp conus portion 8 in the lower end side of earth auger 5.
(the step of foundation improvement construction method example)
Next, referring to Fig.1~Fig. 5 illustrates to have used the foundation improvement of the earth auger 5 involved by present embodiment to construct
The step of method.
Foundation improvement construction method involved by present embodiment is particularly effective for containing ground humous
Base improves construction method, even if being free from ground humous can also be applicable in.In general, containing ground humous
In, since the ingredient of the humic acid contained by the fertile soil hinders the compression effect of ground, foundation improvement becomes tired
It is difficult.Shown in embodiment as be described hereinafter, even the foundation improvement construction method whole amount involved by present embodiment is fertile soil
Also compression effect can be played, therefore, even also playing the same above effect without ground humous.
Similarly, it in the foundation improvement construction method involved by present embodiment, can also be used containing corruption as aggregate
The aggregate of soil is grown, for example, can more preferably can to use fertile soil relative to the ratio that aggregate total amount is 50 weight % or more
Aggregate whole amount is set as fertile soil.For example, the fertile soil being discharged by the excavation of earth auger can be directly used, therefore,
The expense of foundation improvement construction method can be controlled.
In foundation improvement construction method involved by present embodiment, first, carry out foundation improvement ground exterior portion 3, into
Row test drilling (boring) simultaneously takes sample from underground mining, carries out defined experiment.Aftermentioned various data are calculated as a result,.
Next, by making earth auger 5 be rotated on excavation direction, as depicted in figs. 1 and 2, the digging of prescribed depth is formed
Dig hole 11.Later, as shown in figure 3, making earth auger 5 with low speed and reverse, from ground exterior portion 3 to the excavated hole 11, input at least contains corruption
Grow the aggregate of soil 12.At this point, the axial force for the vertical load W for being applied to earth auger 5 is set as 2~3 tons or so, by earth auger 5
Rotating speed be set as 25 turns per minute or less, preferably per minute 20 turn left the right side.
By the way that the vertical load W and rotating speed that are applied to earth auger 5 are set as above-mentioned value, 14 energy of fertile soil 12 and curing materials
The power towards horizontal direction is enough effectively obtained, so as to effectively compress the ground around excavated hole 11.In addition, wrapping
When the dead weight for including earth auger 5 and rotary unit 4 is 2~3 tons or so, in the example, additionally setting is born a heavy burden etc., and can be obtained vertical
Straight load W.In addition, when vertical load W is set to larger, rotary unit 4 be arranged heavy burden (not shown) or by
Rotary unit 4 link wire rod (not shown) etc. and by the wire coil around etc. add downward load.
Fertile soil 12 can for example use the fertile soil being discharged by the excavation of earth auger 5.
Extremely it is less than 10%, preferably 6% or so as the input amount of fertile soil 12,6% or so to improve ground volume
To 7% or so.In addition, it refers to that the area in place of improveing ground is multiplied by obtained by the excavating depth of excavated hole 11 to improve ground volume
Value.
So after input fertile soil 12, on one side make the reversion of earth auger 5, while put into the fertile soil 12 of specified amount, then, such as
Shown in Fig. 4, curing materials 14 are put into excavated hole 11.Curing materials 14 are acted on by the screw conveyor of the earth auger 5 of reversion
And it is delivered to the lower part of excavated hole 11, the depth direction throughout excavated hole 11 is whole.After the input of curing materials 14, also lead to
Crossing makes earth auger 5 invert, and increases the lateral stress generated by input fertile soil 12 and curing materials 14, generates excavated hole 11
The excess pore water pressure of surrounding simultaneously promotes to drain, and thus promotes to compress.In addition it is also possible to which excavated hole 11 can be blocked in input
After the fertile soil 12 of degree, the curing materials 14 of specified amount, later, additional input fertile soil 12 are put into.
If earth auger 5 is made to invert, for fertile soil 12 and curing materials 14, in excavated hole 11, mainly grain size
Big curing materials 14 move to outer peripheral side.This phenomenon faster when its grain size is bigger with the sinking speed of the particle in liquid
It is similar, it changes for an example, is to occur similar phenomenon more in front with particle bigger when mud-rock flow.In addition, due to grain size
Greatly, the time is needed with reacting for moisture, therefore, is easier to move to outside.
As the type of curing materials 14, can use aluminum sulfate and quick lime, blast-furnace cinder, cement with defined point
Measure the material being obtained by mixing.For the detailed content of curing materials 14, it is described in detail below.
As the input amount of curing materials 14, usually relative to fertile soil generally 7 weight % or so.
The grain size of curing materials 14 is preferably greater than the grain size of fertile soil 12, specifically, for 30mm or more 60mm hereinafter, excellent
It is selected as 40mm or more 50mm or less.When the grain size of curing materials 14 is less than 30mm, the movement of curing materials 14 outward sometimes is not
Fully.In addition, be due to be difficult to obtain as commercially available product when the grain size of curing materials 14 is more than 50mm aspect economically, with
And it is applied to the resistance of the excavation wing 7 of earth auger 5 when more than 50mm and becomes larger and is difficult to be transmitted to the bottom of excavated hole 11.
(effect of foundation improvement construction method)
The effect of foundation improvement construction method involved by present embodiment for above description illustrates.Stirring is viscous
When property soil, cohesive soil liquid.If cohesive soil placed with the state, loses the property of fluidity and becomes hard state,
But in the stirring be random and when being pressurizeed with approaching the stress of static (close to the situation of static state coefficient of earth pressure), structural arrangement from
Incomplete orientation texture becomes orientation texture.The phenomenon is known as contact metamorphism.
On the other hand, in the Fill Test of highway etc., observe between actual shift value and theoretical value there is difference
Different, which is interpreted the increase of the shear strength caused by anisotropy compresses.That is, when studying the factor in ground, respectively
It is special situation to be compressed to the same sex, and effectively soil covering pressure is different with the lateral value of confining pressure under normal conditions.In ground
Deformation only occur on vertical (vertical) direction, and do not deform upon in the horizontal direction.Therefore, such ground will be met
In stress and the compression experiment of condition of deformation be known as present K0 experiment.The value and 0.95-sin of static coefficient of earth pressure K0
Φ ' approximate (Φ ' is the internal friction angle in soil).
Also, by one side with apply with the close power of static coefficient of earth pressure general horizontal direction stress, while delay
Slow pressurization, to which the increase of stress almost evenly occur in ground.The pressurization can be by making earth auger 5 invert and controlling
Its weight and rotating speed are adjusted.
In this way, by making to extend through the reversion of the earth auger 5 in ground, fertile soil 12 is pressed into soft soil foundation, in ground
In make native stake 15 and promote to compress effect, and using being caused by curing agent, pore water and the soil particle on 15 periphery of soil stake
A series of chemical reaction, it is a wide range of to promote the compression effect (physical effect) of ground, and can continue to bond for a long time
(cementation) (chemical result).
Physically, being made by native stake 15 makes lateral stress increase and generate excess pore water pressure and promote to drain, by
This promotes to compress.Native stake 15 hardly happens consolidation settlement in itself and support force is also big, therefore, contributes to the branch for increasing ground
Support force.
(curing materials)
As the type of the curing materials 14 in the foundation improvement construction method involved by present embodiment, can use will
The material that aluminum sulfate and quick lime, blast-furnace cinder, cement are obtained by mixing with defined component.
《Aluminum sulfate》
In general, in ground humous, pass through the foundation improvement construction method using earth auger of above description
It is unable to get the compression effect of ground.This is because the ingredient for deriving from the humic acid contained by fertile soil hinders the compression effect of ground
Fruit.
However, the ingredient by the way that aluminum sulfate to be used as to curing materials, makes fertile soil condense, reduce surface area, thus, it is possible to
Enough inhibit the obstruction reacted caused by humic acid.In addition, aluminum sulfate is faintly acid, the pH of soil after inhibiting curing process is played
Rise and remains neutral effect.
In addition, as aluminum sulfate, anhydrous aluminium, 14~18 hydrate of aluminum sulfate etc. can be enumerated, the present invention does not have in this respect
There is restriction, but, it is preferable to use 16 hydrate of aluminum sulfate from the viewpoint of availability.
The content of aluminum sulfate is set as preferably with respect to the total weight of curing materials in the range of 3 weight of weight %~5 %.Sulphur
When the content of sour aluminium is less than 3 weight %, there is the worry for decreased effectiveness humous, in addition, when more than 5 weight %, have
Harmful effect may be brought to the exothermic reaction of quick lime.
《Quick lime》
Quick lime is with lime stone (CaCO3) it is raw material, cause decarbonization by carrying out firing in 900 DEG C or more of high temperature
(de- CO) is generated.
Quick lime CaO generates moisture and white lime Ca (OH) in fertile soil2.In the reaction, such as quick lime 10kg
When becoming white lime, the water of the about 4.3kg of the pore water in soil is made to become the crystallization water.In addition, generated heat promotes pore water
Evaporation.In the soil of the high cumulative water-oil ratio such as fertile soil, the decline of cumulative water-oil ratio goes far towards intensity performance.
The content of quick lime is set as preferably with respect to the total weight of curing materials in the range of 30 weight of weight %~35 %.
When the content of quick lime is less than 30 weight %, the reduced capability of cumulative water-oil ratio is reduced, it is possible to which intensity performance reduces, in addition, being more than
When 35 weight %, quick lime saturation, it is possible to reduce the intensity of conditioned soil.
《Blast-furnace cinder》
Blast-furnace cinder refers to that slag by-produced when will be manufactured the pig iron using the blast furnace of steel mill is carried out obtained from Crushing of Ultrafine
Substance.Blast-furnace cinder has the calcium hydroxide that is generated due to the hydration reaction with the gypsum in cement and the spy being cured
Property, thus improve the intensity of soil.
As blast-furnace cinder, slow cooling slag, granulated blast furnace slag (granulated blast furnace can be enumerated
Slag) etc., small from grain size and consider, it is preferable to use granulated blast furnace slag with the mixed uniformly viewpoint of other compositions.
The content of blast-furnace cinder is set as the range of 30 weight of weight %~35 % preferably with respect to the total weight of curing materials
It is interior.When the content of blast-furnace cinder is less than 30 weight %, there are the insufficient worries of intensity, when more than 35 weight %, it is possible to water
The zone of action of mud carrys out harmful effect.
《Cement》
Cement refers to：The object that raw material comprising lime stone, clay, silica etc. will be dried, crushed, is obtained by mixing
Matter is burnt into kiln, is quenched and clinker is made, and gypsum and other materials are added in clinker and carries out Crushing of Ultrafine and obtains
Substance.
Gypsum contained in the cement is the mineral using calcium sulfate as principal component, by being reacted with above-mentioned blast-furnace cinder
Solidification, to improve intensity humous.As the type of gypsum, do not limit in the present invention, can use anhydrous gypsum,
Semi-hydrated gypsum, dihydrate gypsum etc..
It as the type for the cement that can be used, is not particularly limited, silicic acid specified in JIS R 5210 can be used
Eco-cement etc. specified in blended cement, JIS R 5204 specified in salt cement, JIS R 5211~5213.
The content of cement is set as preferably with respect to the total weight of curing materials in the range of 25 weight of weight %~30 %.Water
When the content of mud is less than 25 weight %, intensity humous performance is likely to decrease, in addition, when more than 30 weight %, it is right
It is affected with reacting for quick lime blast-furnace cinder, it is possible to which intensity is insufficient.
In addition, in the present embodiment, the embodiment as preferred curing materials has used cement, but can also make
With gypsum, rather than cement.
