Description
Technical field
The utility model is related to the Construction Techniques for Cement Mixing Pile in field of civil engineering, is especially a kind of deep-layer stirring
Stake machine.
Background technology
With the fast development of national economic development, especially building construction and the extensive rise of urban construction, cement is stirred
The construction technology of stake is mixed also in continuous development and application.Foundation stabilization being applied to cement mixing pile or in foundation pit supporting system more
Make supporting construction and water-stop curtain.
Traditional cement mixing pile machine includes pile frame, unit head, hollow shaft, feed pipe for mortar, pump for mortar transmission, slurries stirring
Machine, appendix and air compressor machine；Unit head is arranged on pile frame, and shaft is arranged on unit head, shaft lower end Jing ring flanges
It is fixed with a stirring-head with blade；Stirring-head bottom is fixed with whitewashing mouth and air nozzle, whitewashing mouth Jing feed pipe for mortar and defeated slurry
Pump is connected, and pump for mortar transmission is connected with slurries mixer；Air nozzle Jing appendixs are connected with air compressor machine, and air nozzle is linked in whitewashing mouth
Outward, appendix is linked in outside feed pipe for mortar.
The formation of pile of the cement mixing pile of prior art stirs two sprays for four, specifically：After stake machine is in place；Drive stirring
Axle rotates and is drilled down in the soil body, until getting into a bottom designed elevation under stirring-head；Shaft is promoted upwards so that shaft
Rising is rotated while gunite, i.e. rotary jet grouting, until stirring-head is lifted to design of pile top absolute altitude；Second downwards
Drilling shaft, until getting into a bottom designed elevation under stirring-head；Shaft and rotary jet grouting are promoted upwards for the second time, until stirring
Mix head and reach design of pile top absolute altitude.
There is following defect in traditional stake machine：Firstly, since whitewashing mouth is located at stirring-head foot, then the essence of churning
Process is exactly first to stir the soil body by the blade cuts on whitewashing mouth top, then sprays cement mortar, but cement mortar in soil by nozzle
Poor fluidity in body, and the deeper resistance of soil layer is bigger, plus blade stirring is uneven, causes the not fine and close inequality of cement mortar of deep layer
It is even, seriously reduce pile quality；To improve pile quality, mixing time and injection pressure can only be increased, such as stir two sprays using four,
This certainly will just increase materials and cost and extend the duration；And, the stake footpath of last pile is affected by spray pressure, the soil body
Depth is deeper, and resistance is bigger, therefore under same spray pressure, stake footpath necessarily up big and down small disunity, which results in reality
During the churning of border, spray pressure is difficult to hold, and pressure is too big then to increase cement mortar consumption and cost, the too little then pile of pressure
The phenomenon that afterwards the clinch presence between stake and stake is not overlapped or effect is poor, does not have water seepage prevention effect if for water-stop curtain
Really, for support pile then build-in effect on driving birds is not good.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of energy so that soil cement dense uniform, the saving of pile
Slurries consumption, pile quality are good, it is same to guarantee the stake footpath after pile and can improve efficiency of construction, reduction of erection time, save mechanical stage
The deep-mixing pile driver of student contributions pooled to pay for class activities and labour cost.
Technical solution of the present utility model is to provide a kind of deep-mixing pile driver, it include pile frame, unit head, in
Empty shaft, feed pipe for mortar, pump for mortar transmission, slurries mixer, appendix and air compressor machine；Unit head is arranged on pile frame, shaft
On unit head, shaft lower end Jing ring flanges are fixed with stirring-head；Stirring-head is provided with whitewashing mouth and air nozzle, whitewashing
Mouth Jing feed pipe for mortar is connected with pump for mortar transmission, and pump for mortar transmission is connected with slurries mixer；Air nozzle Jing appendixs are connected with air compressor machine, jet
Mouth is linked in outside whitewashing mouth, and appendix is linked in outside feed pipe for mortar；Stirring-head is provided with the blade of at least two groups of differing heights, whitewashing
The height of mouth and air nozzle is located between two groups of blades, and whitewash mouth and air nozzle are located in stirring-head and both spouts stretch out and stir
Mix outside head, the extended line of both spouts intersects with the blade of bottom, intersection point is located at the end of the blade.
The utility model deep-mixing pile driver compared with prior art, with advantages below and effect：
Firstly, since air nozzle and whitewashing mouth are respectively positioned between two-layer blade, and it is downward angular injection, so,
From for the angle of cutting, the secondary oblique cutting of whitewashing is increased outside the horizontal resection of two blades again, therefore cutting soil is imitated
Fruit is more preferable, but importantly, in going down process, after spraying cement mortar, one group of blade above spout can also be to water
Mud is stirred in time, and equally, during upper pulling out, after spraying cement mortar, one group of blade below spout also can be right
Cement mortar is stirred in time, equivalent to after whitewashing to increased one whipping process more, therefore has increased considerably slurries in the soil body
In mobility so as to diffusion is uniform, and the uniformity and compactness after pile is significantly improved；Moreover, significantly improving pile matter
On the premise of amount, also without spray pressure and mixing time is increased as prior art, successfully the four of prior art are stirred
Two sprays are substituted for two and stir two sprays, i.e., when boring down before whitewashing, one group of blade below spout can be beforehand with a water to the soil body
Putting down to cutting causes the soil body to loosen, and is easy to slurries to spread, it is same on when pulling out before whitewashing, one group of blade above spout also can
In advance level causes the soil body to loosen to cutting, is equally easy to slurries to spread, therefore efficiently reduces spray pressure and whitewashing duration,
Reduce slurries consumption；And two stir one on the other, can also simplify construction procedure on the premise of mixing uniformity is improved, improve
Efficiency of construction, shortens the duration, saves machine-team expense and labour cost；And, air nozzle and whitewashing mouth extended line and bottom leaf
The end of piece overlaps, i.e., terminate in the end of blade from the whitewashing post of spout injection, so, no matter spray pressure size, after pile
Stake footpath it is equal all the time up and down, effective control stake footpath size prevents the hidden danger of follow-up leak or build-in effect on driving birds is not good.
Used as improvement, the length direction level of blade, but the width of blade have one and cut with the axis of shaft
Angle [alpha] is cut, thus it is ensured that the blade horizontal resection soil body on the whole, while so that blade is in width slight inclination, it is right to strengthen
The cutting effect of the soil body.
As improving again, the 3rd group of blade, so, the soil body are additionally provided with whitewashing mouth and air nozzle sustained height on stirring-head
Whitewashing after being cut is more smooth, and can further strengthen cutting and mixing effect, further improves pile quality.
