Description
Technical field
This utility model relates to technical field of civil engineering, leads with foundation engineering technology further to traffic municipal administration roadbed
Territory, specifically relates to the technical field of soft soil consolidation process.
Background technology
Along with the implementation that develops rapidly and build a well-off society in an all-round way of Urbanization Construction, to traffic, municipal administration and ground
The foundation basic construction technology that lower spatial construction relates to requires more and more higher, cement mixing method technology, as one flabbily
Base consolidation process and the green technology forming water-stop curtain, reached to widely popularize application.For this to its construction quality and construction
Efficiency proposes higher requirement.But, existing single shaft and multi-shaft cement mixing pile construction quality and construction efficiency are got over
More to meet current foundation engineering growth requirement, while affecting construction quality and duration, occur in that substantial amounts of engineering
Accident, causes huge economic loss.
For existing single shaft mixing pile machine, Double shaft stirring stake machine and the Construction Course Analysis of three axes agitating pile machine, permissible
Find out: existing single shaft mixing pile machine as shown in Figure 1A, X1 be drilling rod, X2 be blade, X3 is mouth spray, and mouth spray is positioned at drill bit
Position, lower brill is whitewashed.Its construction technological process can be seen from sequential Figure 1B, when above carrying shaft, the serosity of injection can not in time with
Soil shear failure mixes, and also can have impact on the quality of reinforcing.
Existing Double shaft stirring stake machine as shown in Figure 2 A, X1 be drilling rod, X2 be blade, X3 is mouth spray, intermediate arrangement one
Root shotcrete pipe X4, mouth spray is positioned at the top of paddle, and stirring vane is distributed near drill bit in a segment limit.Lower boring is stirred not
Whitewashing, whitewashing stirring when above carrying, when sequential shown in 2B, existing Double shaft stirring pile constructing process requires that two sprays three are stirred, and i.e. stirs
Mix a blade to push up low the circulation altogether six times of stake from stake and could meet requirement.In the bottom of mixing pile, the soil body is stirred broken, but
The serosity such as cement cannot spray into and mix with the soil body, because mouth spray is broken always situated in the top of stirring vane, the soil body of bottom
Can not get the mix and blend of cement mortar after broken, create one section of weak pile body, middle strength of the mixing pile is apparently higher than both sides, such as figure
Shown in 2C.
Existing three axes agitating pile machine as shown in Figure 3A, X1 be drilling rod, X2 be blade, X3 is mouth spray, intermediate agitation axle
X3 is jet bottom drill bit, and both sides shaft is whitewashed in the bottom of drill bit.Lower brill and on all whitewash, such as sequential chart when carrying shaft
Shown in 3B.Owing to mouth spray is positioned at both sides, the grout distribution of injection is that centre is few, and both sides are many, cause stir pile body intensity in
The distribution that middle low both sides are high, as shown in Figure 3 C.
Existing single shaft and multi-shaft stirring ram machine construction process are primarily present following problem:
1), in existing mixing pile machine, its mouth spray or be positioned at the bottom position (i.e. stirring vane bottom) of drill bit,
Being positioned at the upper position of stirring vane, when going down process is whitewashed, Rock And Soil is not stirred loosening, and the serosity of injection expands
Scattered gap is the least, and the radius of its diffusion is the least；When proposing brill whitewashing, serosity along the diffusional resistance ratio of drilling rod to the diffusion of surrounding
Resistance is little, occurs returning slurry phenomenon in a large number, and the outer liquid loss amount of serosity is bigger；
2), existing Soil-cement method fully spread requirement in order to reach serosity, increase by increasing the ratio of mud
Adding whitewashing amount, so that the water content of soil cement increases, intensity reduces；
3), the mouth spray skewness of existing mixing pile machine, make serosity stirring pile body in can not uniformly spread, lead slurry
Liquid is the most uneven with the mixing in Rock And Soil, and the intensity distributions of stirring pile body is also serious uneven；The every width of existing three axes agitating pile
Between set play connect, further exacerbate the inhomogeneities of this intensity distributions.
4), in two existing axles or triaxial cement blender, whitewash and can not carry out with stirring simultaneously so that the slurry of injection
Liquid can not stir in time, and occurs returning slurry phenomenon in a large number, wastes a large amount of reinforcement material；
5), the mixing pile machine power of single shaft and Double shaft stirring stake little, wear that to bore the ability of soil layer low, the degree of depth that stirring is reinforced is relatively
Shallow, it is impossible to meet the requirement that Deep Thick Soft Ground is reinforced；
6), the paddle of existing mixing pile machine is distributed only over the high scope of drill bit one meter above and rotating speed is relatively low, stirring
Blade is few with the contact probability of the soil body, it is impossible to is sufficiently stirred for the soil body by solidification cement mortar and cuts, often in big complete soil
Having not a particle of serosity in block, the stirring wall uniformity of formation and density are poor.The quality of water-stop curtain there is is large effect,
Be not suitable for the water-stop curtain formed in the grittiness soil body.Mouth spray is positioned to the Double shaft stirring stake on stirring vane top, meeting
Form a skylight in the bottom of mixing pile, be not suitable for use in sealing or foundation stabilization.
7), pile efficiency is low.Either single shaft, twin shaft or three axles, pile efficiency all ratios are relatively low.Single shaft mixing pile machine is every
Secondary pile effective width only has 400～700mm, the effective width of each pile of Double shaft stirring stake be only 1.0m (withDouble
As a example by axle mixing pile)；Three axes agitating pile each pile effective width is also only 1.2m.And due to pile limited width,
Cause the frequent telephone-moving of equipment, be substantially reduced working performance.
8), Mechanization Level is low.Existing uniaxially or biaxially mixing pile equipment mostly is away tubular type, and equipment moves and easily inclines slowly
Covering, the amount of labour of telephone-moving is big；Boring and promote speed under stake machine perpendicularity, drilling rod slow, moment of torsion is little, and the cutting power of drill bit is little, complete
Entirely depending on Artificial Control speed, error is relatively big, affects pile quality；
9), the control of the key index such as the ratio of mud, additive incorporation, slurry flow rely primarily on manually, exist bigger
Error, affects pile quality；
10), overlap difficult quality guarantee between every width stake stake of existing single shaft and Double shaft stirring stake, easily cause foundation ditch and ooze
Leakage.Existing single shaft cement-soil stirring pile construction equipment is as it is shown in figure 1, it can be seen that a pile of once constructing, by stake
Between overlap joint form continuous piling wall, owing to the diameter of drilling rod is less, its rigidity is little, easily deforms, in addition position error and vertical
Degree error, it will make the amount of lap of design become negative, shows as mixing pile in bottom in the axial direction or along being perpendicular to axis
The opening in direction.Formed diaphragm wall by single shaft mixing pile, owing to overlapping the slot is many, then occur that the probability of open seam is higher.
The problem of above-mentioned existence sums up and is mainly caused by limitation of both construction equipment and construction technology,
These problems the most seriously hinder application and the development of mixing pile technology.Therefore, to soil cement strengthening construction equipment and construction party
The research and development of method are very important with innovation.
