Description
The application is that number of patent application is 201410813752.X, and patent name is the construction of the water-stop curtain of soil removal and replacement stirring
Method, the original bill applying date are the divisional application of 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 construction method based on gravel.
Background technique
When the higher Construction of Deep Excavation Engineering of underground engineering especially level of ground water, it is often necessary to be set on the outside of support pile
Water-stop curtain is set, water-stop curtain is generally formed using continuous cement mixing method.When water-stop curtain is in the depth bounds of design
It inside encounters the geological stratification for being difficult to pass through, such as when gravel layer, hard skerry and erratic boulder, is stirred using conventional soil cement
Stake machinery is mixed, such as two axis cement-soil mixing pile machines, triaxial cement mixing pile machine are difficult to completion of constructing.
For the skerry for being difficult to pass through, can be used single tube high-pressure rotary-spray equipment it is stirred point by point in advance it is loose, then
It constructs again cement mixing method, but this method can not still implement deep gravel layer and erratic boulder.
Interlocking pile or ground-connecting-wall can be used for deep gravel layer and erratic boulder, while playing supporting and sealing
Effect.It is high to the quality stability requirement of ultra-retardation concrete but when occlusion pile driving construction, and the A stake of interlocking pile and B
Between easily leaked due to being glanced off in the direction perpendicular to wall.Ground-connecting-wall seam crossing is the easy hair position for generating leakage,
It can effectively avoid joint using two-wheel flute milling machine to leak, but the high process cost, and ground-connecting-wall cost itself is higher,
Be not suitable for all engineerings.
TRD engineering method can easily cope with hardpan, such as cobblestone, sticky mud, sandstone, oil shale, limestone, Hua Gang
Rock etc., stirs evenly, and malocclusion is not present, it is ensured that the high continuity of wall 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 of the prior art and provide a kind of soil removal and replacement stirring water-stop curtain based on gravel
Construction method, design is scientific and reasonable for this method, is used for water seal for deep foundation pit curtain, and simple process, construction cost are low, makes full use of often
Water-stop curtain water-stagnating effect with construction machinery, completion is good, and construction safety is reliable.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of the step of soil removal and replacement stirring water-stop curtain construction method based on gravel, method are as follows:
(1), pilot hole stake position is discharged by cement mixing pile axis；
(2) steel pile casting, is buried, hole wall is stablized using mud, matter to be cut the earth in hole is taken out in Spiral digging machine wet work；
(3), observation drilling bucket takes out matter situation to be cut the earth, and determines and removes churning driven after pilot hole depth, drilling reach pilot hole depth
Machine continues to stablize using mud hole wall until pilot hole and backfilling operation space are met the requirements；
(4) mud in stake holes, is excluded using gaslift plasma discharge machinery, backfills pile earth material, controls plasma discharge amount and backfill amount phase
It answers；
(5) backfill completes distance and meets cement mixing pile to work continuously requirements, leads in the digging plasma discharge of cement mixing pile axis both sides
Ditch；
(6) cement mixer is in place, and cement slurry stirring system operation pump slurry, starting stake machine carries out cement mixing pile driving construction；
(7) the remaining untreated sandwich portion in adjacent two pilot holes stake holes position is completed soil removal and replacement and is stirred by Mixing Machine action of forced stirring
The water-stop curtain construction mixed.
Moreover, 1000@1200 of pilot hole stake position φ is discharged by three axes agitating pile axis in the pilot hole stake position.
Moreover, the high 2m of the steel pile casting, steel pile casting diameter are 20cm bigger than design stake diameter, it is flat that steel pile casting top surface is higher by construction
Platform 30cm.
Moreover, manual labour skill is jumped in the Spiral digging machine wet work draws stake holes, drawing stake holes is φ 1000mm.
Moreover, the matter to be cut the earth is gravel, cobble or erratic boulder.
Moreover, the starting stake machine carries out cement mixing pile driving construction as the construction of 850 1200 three axes agitating pile of φ.
The advantages and benefits of the present invention are:
1, the water-stop curtain of this soil removal and replacement stirring is to be unfavorable for pile containing taking-up in the stratum such as dust, cobble, erratic boulder
Soil property, while the material for being conducive to pile (at wall) is backfilled, continue the construction of mixing pile.This method construction quality is protected
Card, construction machinery tissue is limited smaller by market.
2, the technology maturation of water-stop curtain, simple process of this soil removal and replacement stirring, low in cost, make full use of common construction machine
The water-stop curtain water-stagnating effect of tool, completion is good.
Detailed description of the invention
Fig. 1 is the schematic diagram of rotary digging pilot hole of the present invention；
Fig. 2 is the schematic diagram that the present invention completes construction cement mixing pile.
Wherein 1 is cement mixing pile, and 2 be pilot hole, and 3 be original ground, and 4 be the unfavorable interlayers such as dust, cobble, erratic boulder, and 5 are back
The earth material filled out, 6 be level of ground water, and H1 is water-stop curtain supporting column length, H2 be dust in water-stop curtain support post depth bounds,
The unfavorable interlayer geology buried depth such as cobble, erratic boulder, H3 are unfavorable interlayer geology thickness.
