Description
Technical field
The invention belongs to water-stop curtain field, the construction of the water-stop curtain of a kind of soil removal and replacement stirring
Method.
Background technology
During the higher Construction of Deep Excavation Engineering of underground engineering particularly level of ground water, it is often necessary to
The outside of fender pile arranges water-stop curtain, and water-stop curtain typically uses continuous print cement mixing method to be formed.
When water-stop curtain design depth bounds in run into the geological stratification being difficult to pass through, as gravel layer,
When hard skerry and erratic boulder etc., use the cement-soil mixing pile machine tool of routine, such as two axle water
Earth mixing pile machine, triaxial cement mixing pile machine etc. are difficult to construction to be completed.
For being difficult to the skerry that passes through, single tube high-pressure rotary-spray equipment can be used its pointwise to be stirred in advance
Dynamic loose, cement mixing method of constructing the most again, but the method for deep gravel layer with
And erratic boulder still cannot implement.
Interlocking pile or ground-connecting-wall can be used for deep gravel layer and erratic boulder, simultaneously work as
Supporting and the effect of sealing.But during interlocking pile construction, the quality stability to ultra-retardation concrete
Require high, and easily owing to sending out in the direction being perpendicular to wall between the A stake of interlocking pile and B stake
Raw deflection and seepage.Ground-connecting-wall seam crossing is the easily position producing seepage, uses two-wheel flute milling machine
Joint seepage can be prevented effectively from, but this process costs is higher, and the cost of ground-connecting-wall own is relatively
Height, is not suitable for all engineerings.
TRD engineering method can easily tackle hardpan, such as cobblestone, viscosity mud, sandstone, oil mother
Shale, limestone, granite etc., stir, there is not malocclusion, it is ensured that body of wall is high continuously
Property and high sealing, but TRD engineering method cost is high.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the sealing of a kind of soil removal and replacement stirring
The construction method of curtain, the method design science is reasonable, for water seal for deep foundation pit curtain, technique is simple,
Construction cost is low, makes full use of common construction machinery, and the water-stop curtain stagnant water effect completed is good, executes
Work is safe and reliable.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of construction method of the water-stop curtain of soil removal and replacement stirring, the step of its method is:
(1), discharge by cement mixing pile axis and draw stake position, hole；
(2), burying steel pile casting underground, use mud to stablize hole wall, Spiral digging machine wet work is dug waiting in hole
Soil property is taken out；
(3), observing drilling bucket and take out and treat shoveling matter situation, determine and draw hole depth, boring reaches to draw hole depth
Removing rotary drilling rig after degree, continuing to use mud stablize hole wall until drawing hole and backfilling operation space is expired
Foot requirement；
(4), use gaslift plasma discharge machinery to get rid of mud in stake holes, backfill pile earth material, control plasma discharge
Measure corresponding to backfill amount；
(5) backfilled distance to meet cement mixing pile and work continuously requirement, at cement mixing pile axis
Plasma discharge guide channel is dug on both sides；
(6) cement mixer is in place, and cement mortar stirring system runs pump slurry, starts stake machine and carries out cement
Mixing pile construction；
The most adjacent two draw stake holes position, hole remains untreated sandwich portion, by Mixing Machine action of forced stirring,
Complete the water-stop curtain construction of soil removal and replacement stirring.
And, described stake position, hole of drawing is discharged by three axes agitating pile axis and is drawn stake position, hole φ
1000@1200。
And, described steel pile casting height 2m, steel pile casting diameter is than the design big 20cm in stake footpath, steel pile casting
End face exceeds operation platform 30cm.
And, described Spiral digging machine wet work is jumped manual labour skill and is drawn stake holes, and drawing stake holes is φ 1000mm.
And, described treats that shoveling matter is gravel, cobble or erratic boulder.
And, it is the stirring of φ 850 1,200 3 axle that described startup stake machine carries out cement mixing pile driving construction
Pile driving construction.
Advantages of the present invention and having the beneficial effect that
1, the water-stop curtain of this soil removal and replacement stirring is to take out in containing stratum such as dust, cobble, erratic boulders
It is unfavorable for that the soil property of pile, backfill simultaneously are beneficial to the material of pile (one-tenth wall), proceed stirring
The construction of stake.This method construction quality is guaranteed, and construction machinery tissue is limited less by market.
2, this soil removal and replacement is stirred the technology maturation of water-stop curtain, technique are simple, with low cost, fully
Utilizing common construction machinery, the water-stop curtain stagnant water effect completed is good.
Accompanying drawing explanation
Fig. 1 is that the present invention is revolved and dug the schematic diagram drawing hole；
Fig. 2 is the schematic diagram that the present invention completes construction cement mixing pile.
Wherein 1 is cement mixing pile, and 2 for drawing hole, and 3 is original ground, and 4 is dust, cobble, drift
The unfavorable interlayer such as stone, 5 is the earth material of backfill, and 6 is level of ground water, and H1 is water-stop curtain supporting column length
Degree, H2 is the unfavorable interlayer geology such as dust, cobble, erratic boulder in water-stop curtain support post depth bounds
Buried depth, H3 is unfavorable interlayer geology thickness.
