Abstract
The utility model relates to a cement mixing pile device capable of realizing up and down slurry spraying shifting. The device is reconstructed and optimized based on an original cement mixing pile machine. The device comprises a movable hoop blade, a fixed sleeve, a mixing blade, a drill pipe and a slurry spray nozzle combination. The movable hoop blade automatically closes or opens upper and lower slurry spray nozzles under the action of mechanical force according to different mixing directions, and slurry is sprayed from the bottom when the drill pipe drills and sprayed from the upper part when the drill pipe is lifted. Compared with the prior art, the device has the advantages of uniform mixing, high mixing efficiency, low cost, high efficiency, short construction period and the like.
Description
Technical field
The present invention relates to a kind of cement mixing method device that can change whitewashing up and down, be mainly used in bracing of foundation pit sealing and ground stabilization in civilian and the industrial infrastructure construction.
Background technology
At present general bracing of foundation pit sealing and ground stabilization two agitation piles, three agitation piles, SMW worker's method, five agitation piles of FCW, six agitation piles of adopting more.
Cement mixing method is to be used to reinforce saturated and a kind of method soft clay ground, it utilizes cement as curing compound, by special Mixing Machine, in the ground depths weak soil and curing compound are forced to stir, utilize a series of physical-chemical reactions that produced between curing compound and the weak soil, weak soil is hardened become to have the high-quality ground of globality, water stability and certain intensity.
Conventional mouth spray is all in the bottom whitewashing, when carrying in the drilling rod counter-rotating cement paste can not get stirring cause stirring inhomogeneous.This invention has solved when carrying in the drilling rod counter-rotating, and cement paste can not get stirring, and stirs inhomogeneous.
Summary of the invention
Purpose of the present invention is exactly in order to overcome inhomogeneous in the middle of stirring, to stir less than the soil cement slurry that has just gushed out when for example carrying on the drilling rod.
A kind of cement mixing method device that can change whitewashing up and down, this device comprises movable anchor ear blade, fixed cover, stirring vane, mouth spray combination.Described movable anchor ear blade drilling rod direction of rotation is different and rotate, fixedly the anchor ear blade is used for described fixed cover, and described mouth spray makes up by mouth spray and rubber pad to be formed, and is used for the mouth spray switch.
On the described drilling rod respectively on have two mouth sprays, bottom whitewashing during following brill, on top whitewashing when carrying.
Described movable anchor ear blade edge is provided with groove, and movable anchor ear blade rotates in 1 °～90 ° of the angles of regulation, and automatic switch is mouth spray up and down.
Described fixed cover is welded on the drilling rod, and is provided with boss on the fixed cover limit, and restraint anchor ear blade rotates in 1 °～90 ° of the angles of regulation.
Described mouth spray is combined in the mouth spray place and is provided with a mouth spray concentric grooves, is used for fixing rubber pad, and rubber pad is with the fixing mouth spray of screw.
With present technology following characteristics are arranged:
1. mixing evenness obviously improves.
Conventional cement-soil mixing pile machine adopts the bottom whitewashing, the cement paste that is sprayed when bottom whitewashing shortcoming is to carry on the drilling rod can't obtain the stirring of stirring vane, cause stirring uneven phenomenon, and the present invention has 2 whitewashings up and down, bottom whitewashing when drilling rod bores down, top whitewashing when carrying on the drilling rod, on when carrying cement paste can obtain the stirring of stirring vane, solved and stirred uneven phenomenon when putting forward on the conventional cement-soil mixing pile machine drilling rod.
2. stir the time spent shortening.
Because of cement paste stirs, need not to stir repeatedly, obviously shorten mixing cycle, and LVFS can reach 100%.
3. the present invention has wide range of applications, and can be used for diaxon, and three, five are waited multiaxis agitation pile matched with devices to use.

The specific embodiment
Embodiment 1
As shown in Figure 1, agitation pile can be changed the supporting five agitation piles use of refractory gunning equipment up and down.
Handle assembly is installed on the drilling rod as shown in the figure, movable anchor ear blade 1 packs into drilling rod 5 and checks direction, fixed cover 2 is welded on the drilling rod, and the mouth spray on the movable anchor ear blade is aimed at the mouth spray 6.7 on the drilling rod, and assurance activity anchor ear blade rotates freely for 1 °～90 °.Blade is welded on the drilling rod according to the figure paper size.
Below this device five uses above the mixing pile machine.
Specifically may further comprise the steps:
(1) setting-out is emitted full pattern according to working drawing;
(2) open channels requires open channels according to drawing;
(3) device is in place, five cement mixing method devices is moved to treat construction location;
(4) starting backstage cement paste stirring system is delivered to slurry storage bucket to cement paste then.
(5) open integrated computer, the data that allow computer control to set in advance: spray pressure, every meter decrease speed, every meter whitewashing amount, stake end design elevation, total whitewashing amount and total mixing time.
(6) open refractory gunning equipment, main story motor, drilling rod bore bottom mouth spray whitewashing down, and the top mouth spray is not whitewashed.
(7) reverse motors again, limit are carried and are bored the limit whitewashing, and the bottom mouth spray is not whitewashed, the whitewashing of top mouth spray.
(8) as required, form gravity dam and can make Extra-Deep Foundation Pit retaining soil and sealing.
(9) one groups of end move to second group and continue construction.
Claims (5)
1. the cement mixing method device that can change whitewashing up and down, this device comprises movable anchor ear blade, fixed cover, stirring vane, drilling rod and mouth spray combination, described movable anchor ear blade is rotatable, and described fixed cover is the anchor ear blade fixedly, described mouth spray combination is made up of mouth spray and rubber pad, and is used for the mouth spray switch.
