The invention relates to a construction method of a soil replacement stir waterproof curtain based on gravels. The construction method comprises the following steps: (1) a leading hole pile position is cast according to the axis of a cement mixing pile; (2) a steel protection cylinder is embedded; a hole wall is stabilized by mud; soil to be dig in a hole is taken out by a rotary drilling machine through a wet method; (3) the hole wall of the drilled hole is stabilized by the mud until the hole leading and backfill operation space satisfies the requirements; (4) the mud in the pile hole is removed by gas lift mud removing machinery; and pile soil is filled back; (5) the backfill completion distance satisfies the continuous operation requirements of the cement mixing pile; and a mud removing ditch is dig; (6) a cement mixing machine is in place; and the cement mixing pile constructs; and (7) the remained un-treated interlayer part of two adjacent leading hole pile positions is forcedly stirred by stirring machinery to finish construction of the soil replacement stir waterproof curtain. The construction method is scientific and reasonable in design, used for a deep foundation pit waterproof curtain, simple in process and low in construction cost, fully uses common construction machinery, is excellent in waterproof effect of the finished waterproof curtain, and is safe and reliable in construction.
Description
The application is that number of patent application is 201410813752.X, and patent name is stopping of soil removal and replacement stirringThe construction method of water curtain, the divisional application that the original bill applying date is 2014.12.23.
Technical field
The invention belongs to water-stop curtain field, especially a kind of soil removal and replacement stirring water-stop curtain based on gravelCurtain construction method.
Background technology
When the underground engineering Construction of Deep Excavation Engineering that particularly level of ground water is higher, often need to prop upThe arranged outside water-stop curtain of fender pile, water-stop curtain generally adopts continuous cement mixing method to form.When water-stop curtain design depth bounds in run into the geological stratification that is difficult to pass through, as gravel layer,When hard skerry and erratic boulder etc., use conventional cement-soil mixing pile machine tool, as two axle waterEarth mixing pile machine, triaxial cement mixing pile machine etc. are difficult to construct.
For the skerry that is difficult to pass through, can adopt single tube high-pressure rotary-spray equipment in advance its pointwise to be stirredMoving loose, and then construction cement mixing method, but the method for deep gravel layer withAnd erratic boulder still cannot be implemented.
Can adopt interlocking pile or ground-connecting-wall for deep gravel layer and erratic boulder, play simultaneouslyThe effect of supporting and sealing. But when interlocking pile construction, to the quality stability of super retarded concreteRequire high, and between the A stake of interlocking pile and B stake very easily owing to sending out in the direction perpendicular to wallGive birth to deflection and seepage. Ground-connecting-wall seam crossing is an easily position that produces seepage, adopts two-wheel flute milling machineCan effectively avoid joint seepage, but this process costs is higher, and the cost of ground-connecting-wall ownHeight, is not suitable for all engineerings.
TRD engineering method can easily be tackled hardpan, as cobblestone, viscosity mud, sandstone, oil motherShale, limestone, granite etc., stir, and do not have malocclusion, guarantees that body of wall is continuously highProperty and high sealing, but TRD engineering method cost is high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of soil removal and replacement based on gravel is providedStirring water-stop curtain construction method, the method design science is reasonable, for water seal for deep foundation pit curtain, workSkill is simple, construction cost is low, makes full use of common construction machinery, the water-stop curtain sealing effect completingFruit is good, and construction safety is reliable.
The present invention solves its technical problem and is achieved through the following technical solutions:
A soil removal and replacement stirring water-stop curtain construction method based on gravel, the step of its method is:
(1), discharge and draw stake position, hole by cement mixing pile axis;
, bury steel casing underground, adopt mud to stablize hole wall, Spiral digging machine wet work is dug waiting in holeSoil property is taken out;
, observe drilling bucket and take out matter situation to be cut the earth, determine and draw hole depth, boring reaches draws hole depthAfter degree, remove rotary drilling rig, continue adopt mud stablize hole wall until draw hole and backfilling operation space expireFoot requirement;
(4), adopt mud in gaslift plasma discharge machinery eliminating stake hole, backfill pile earth material, control plasma dischargeMeasure corresponding with backfill amount;
(5) backfill completes distance and meets the cement mixing pile requirement of working continuously, at cement mixing pile axisPlasma discharge guide channel is dug on both sides;
(6) cement mixer is in place, and cement mortar stirring system process pump slurry starts stake machine and carries out cementMixing pile construction;
(7) adjacent two draw position, stake hole, hole and remain untreated sandwich portion, by Mixing Machine action of forced stirring,Complete the water-stop curtain construction that soil removal and replacement is stirred.
And the described stake position, hole of drawing is discharged and is drawn stake position, hole φ by three axle mixing pile axis10001200。
And, the described high 2m of steel casing, steel casing diameter is than the design stake large 20cm in footpath, steel casingEnd face exceeds operation platform 30cm.
And described Spiral digging machine wet work is jumped manual labour skill and drawn a hole, drawing a hole is φ 1000mm.
And described matter to be cut the earth is gravel, cobble or erratic boulder.
And it is that φ 8,501,200 3 axles stir that described startup stake machine carries out cement mixing pile driving constructionPile driving construction.
Advantage of the present invention and beneficial effect are:
1, the water-stop curtain that this soil removal and replacement is stirred is to take out containing in the stratum such as dust, cobble, erratic boulderBe unfavorable for the soil property of pile, backfill is simultaneously beneficial to the material of pile (one-tenth wall), proceeds to stirThe construction of stake. This method construction quality is guaranteed, and construction machinery tissue is subject to market restriction less.
Technology maturation, the technique of the water-stop curtain that 2, this soil removal and replacement is stirred are simple, with low cost, fullyUtilize common construction machinery, the water-stop curtain stagnant water effect completing is good.
Brief description of the drawings
Fig. 1 is that the present invention is revolved and dug the schematic diagram that draws 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, 4 for dust, cobble, floatThe 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 lengthDegree, H2 is the unfavorable interlayer geology such as dust in water-stop curtain support post depth bounds, cobble, erratic boulderBuried depth, H3 is unfavorable interlayer geology thickness.
