Description
Technical field
The present invention relates to a kind of cement-soil mixing pile device can changing whitewashing up and down, be mainly used in the bracing of foundation pit sealing in civilian and industrial infrastructure construction and ground stabilization.
Background technology
General bracing of foundation pit sealing and ground stabilization many employings two axle agitation pile at present, three axes agitating pile, SMW engineering method, FCW five axle agitation pile, six axle agitation piles.
Cement mixing method is for reinforcing saturated and a kind of method that is Soft Clay Foundation, it utilizes cement as curing compound, by special Mixing Machine, in ground depths by weak soil and curing compound action of forced stirring, utilize the series of physical chemical reaction produced between curing compound and weak soil, weak soil is hardened into have the high-quality ground of globality, water stability and some strength.
Conventional mouth spray is all in bottom whitewashing, and when drilling rod reversion is carried, cement paste can not get stirring and causes stirring uneven.When this invention solves and drilling rod reversion is carried, cement paste can not get stirring, and stirs uneven.
Summary of the invention
Object of the present invention is exactly uneven in order to what overcome in the middle of stirring, stirs less than the soil cement slurry just gushed out when drilling rod such as, carry.
The present invention is realized by technical scheme below:
Can change a cement-soil mixing pile device for whitewashing up and down, this device comprises Pneumatic valve, inlet pipe one, inlet pipe two, inlet pipe three, drilling rod, upper mouth spray and lower mouth spray; Described Pneumatic valve controls pulp position, and described inlet pipe one, inlet pipe two, inlet pipe three is connected to each other and leads to lower mouth spray, and described drill pipe bore leads to mouth spray.
On described drilling rod respectively on have two mouth sprays, whitewash bottom during lower brill, when above carrying top whitewashing.
Described Pneumatic valve can control the position of grout outlet, and during lower brill, Pneumatic valve stock inlet and inlet pipe one are connected, and when above carrying, Pneumatic valve stock inlet and drill pipe bore are connected.
Described inlet pipe leads to lower mouth spray once inlet pipe two, inlet pipe three.
Described drill pipe bore leads to mouth spray.
A kind of method of operating can changing whitewashing cement-soil mixing pile device up and down comprises:
(1) pull Pneumatic valve gauge tap, to Pneumatic valve inflation, cement paste source and lower mouth spray form path; Open refractory gunning equipment, main story motor, bores under drilling rod, and bottom mouth spray is whitewashed, and top mouth spray is not whitewashed.
(2) pull Pneumatic valve gauge tap, to Pneumatic valve exhaust, cement paste source and upper mouth spray form path; Open refractory gunning equipment, then reverse motors, whitewash in Ti Zuan limit, limit, bottom mouth spray is not whitewashed, and top mouth spray is whitewashed.
Described method of operating can arrange in pairs or groups multi-shaft stirring stake device use.
Following features is had with present technology:
1. mixing evenness significantly improves.
Conventional cement-soil mixing pile machine adopts bottom whitewashing, the cement paste sprayed when bottom whitewashing shortcoming is drilling rod is carried cannot obtain the stirring of stirring vane, cause stirring uneven phenomenon, and the present invention has upper and lower 2 whitewashings, whitewash bottom when boring under drilling rod, top whitewashing when drilling rod is carried, when above carrying, cement paste can obtain the stirring of stirring vane, solves when traditional cements soil mixing pile machine drilling rod is carried and stirs uneven phenomenon.
2. stir used time shortening.
Because cement paste stirs, without the need to repeatedly stirring, mixing cycle obviously shortens, and LVFS can reach 100%.
3. the multi-shaft stirring stake matched with devices such as the present invention has wide range of applications, and may be used for diaxon, three axles, five axles use.
Accompanying drawing explanation
Fig. 1 is the design diagrams of apparatus of the present invention on five axle mixing pile machines;
Fig. 2 is upper and lower mouth spray schematic diagram
Fig. 3 is the principle design figure that whitewashes up and down
Detailed description of the invention
Embodiment 1
As shown in Figure 1, agitation pile can change the supporting five axle agitation piles uses of refractory gunning equipment up and down.
As shown in Figure 3, cement paste mouth commutates through Pneumatic valve 7 and leads to upper and lower two mouth sprays of five axle drill bits respectively.When drilling rod bores for 3 times, inflate to Pneumatic valve 7, cement paste is guided to lower mouth spray 6 through Pneumatic valve 7 end opening through slurry pipe 1, slurry pipe 29, slurry pipe 3 10, bottom whitewashing when boring under realizing agitation pile; When drilling rod 3 is carried, Pneumatic valve 7 is vented, and cement paste directly flows to the supreme mouth spray 5 of drilling rod 3 endoporus, top whitewashing when realizing agitation pile is carried.Blade 2 is welded on drilling rod 3 according to figure paper size.
Be down the use of this device on five axle mixing pile machines.
