Traditional stake machine and utilize the method for conventional piles machine pile to have a very large defect, it is cement grout poor fluidity in the soil body, be difficult to even diffusion, near the cement paste bulk deposition of the mouth that makes to whitewash, and position slurries amount wretched insufficiency slightly far away, and whitewashing mouth is also easily stopped up by hack, naturally cause the soil body to lack cement paste, therefore after stirring, the cement-soil of pile body is not fine and close, inhomogeneous, is seriously lowered into quality of pile; And, along with soil depth increases, it is large that soil body hardness becomes, and slurries are difficult to even diffusion, therefore in the larger soil body of the degree of depth, be difficult to pile, be that the pile degree of depth is limited, be generally no more than 15 meters, or in the original hardness such as sand, clay just in the larger soil body, slurries are more difficult to even diffusion, and nature cannot pile; Equally due to slurries poor fluidity in the soil body, like this, in the process of boring under shaft, the slurries that spray cannot spread, and can only take first lower boring that the soil body is bored to the way of whitewashing when pine is carried shaft on then, like this, need two heavy two to pull out ability pile, efficiency of construction is low, long in time limit, and mechanical stage student contributions pooled to pay for class activities and labour cost are many, deficiency in economic performance.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of and can make the cement-soil of pile fine and close evenly, pile quality is good, can strengthen the pile degree of depth and also can pile in the larger soil body of hardness and can improve the Biaxial Compressive gas rotary ejection type mixing pile machine of efficiency of construction, reduction of erection time, saving mechanical stage student contributions pooled to pay for class activities and labour cost.
Technical solution of the present utility model is, a kind of Biaxial Compressive gas rotary ejection type mixing pile machine is provided, it comprises pile frame, unit head, two parallel shafts, a defeated slurry house steward, two defeated slurries are in charge of, pump for mortar transmission and slurry agitation machine, unit head is arranged on pile frame, shaft is that hollow tubular and two shafts are installed on unit head, every shaft lower end is fixed with a stirring-head with stirring vane through flange, on each stirring-head, be fixed with a whitewashing mouth, each whitewashing mouth is in charge of through defeated slurry, defeated slurry house steward is communicated with pump for mortar transmission, pump for mortar transmission is communicated with slurry agitation machine, every defeated slurry is in charge of in the tube chamber that is arranged on a shaft, it also comprises two air nozzles, an air compressor machine, a gas transmission main and two gas transmissions are in charge of, each air nozzle is fixed on a stirring-head, each air nozzle is linked in outside a whitewashing mouth, each air nozzle is communicated with the tube chamber lower end of a shaft, the lower end that the tube chamber upper end of this shaft is in charge of with a gas transmission is communicated with, the upper end that this gas transmission is in charge of is communicated with one end of gas transmission main, the other end of gas transmission main is communicated with air compressor machine.
The method of utilizing this Biaxial Compressive gas rotary ejection type mixing pile machine pile, its step comprises: pile-forming machine perching is positioned on design stake position the stirring-head of shaft; Drive shaft rotation and pierce downwards and in the soil body, open pump for mortar transmission and slurry agitation machine simultaneously, open again air compressor machine, make shaft rotate lower boring and stir the soil body while whitewashing under the sweeping along of pressure-air, until stirring-head reach at the bottom of design elevation, then rotate up and promote shaft to stir the soil body, whitewashing under the sweeping along of pressure-air simultaneously, until the stirring-head of shaft arrives design of pile top absolute altitude.
The utility model Biaxial Compressive gas rotary ejection type mixing pile machine compared with prior art, has the following advantages and effect:
Adopt after this Biaxial Compressive gas rotary ejection type mixing pile machine, in whitewashing process, compressed air sweeps along slurries to spray from the surrounding of slurries ringwise, like this, spray pressure can rise to 2～4MPa from 0.2～0.4MPa of prior art, significantly increased the mobility of slurries in the soil body, ensure slurries evenly diffusion in the soil body, avoid near slurries bulk deposition and in distant positions slurries quantity not sufficient slightly whitewashing mouth, the mouth that equally also prevents from whitewashing is stopped up by hack, avoid causing due to obstruction the situation of soil body slurries quantity not sufficient, therefore be stirred after blade stirring, the cement-soil even compact of pile body, pile quality is good, and slurries also can evenly spread smoothly in the harder soil body, like this, also can pile in harder sandy soils, argillic horizon, same in the larger soil body of the degree of depth also pile smoothly, significantly increased the pile degree of depth, more than the pile degree of depth of the present utility model can reach 30m, equally because spray pressure increases, slurries mobility in the soil body is strong, like this, bore without the shaft that must first sink the body that loosens the soil and promote again shaft slip casting as prior art, but direct rotary jet grouting in lower brill shaft, by the lower brill of prior art, on pull out slip casting, lower boring again, the process of pulling out slip casting has again become lower brill of the present utility model slip casting, pull up again and slip casting, that is to say, pull out and become one heavy one and pull out two heavy two of prior art, increase substantially efficiency of construction, accelerate speed of application, reduction of erection time, save mechanical stage student contributions pooled to pay for class activities and labour cost, good in economic efficiency.
As improvement, on pile frame, be fixed with a transverse strut, transverse strut is provided with two the first spacing holes, two shaft activities are engaged in the first spacing hole, like this, this horizontal linking beam can make two shafts keep vertically, prevents in going down process that shaft is stressed and off normal is crooked.
As improving again, it also comprises a movable contact beam, movable contact beam is provided with two the second spacing holes, on every shaft, be fixed with the Horizontal limiting plate of twice differing heights, every shaft shaft part between twice Horizontal limiting plate is rotatably linked in the second spacing hole, and like this, movable contact beam can be along with two shaft liftings, in shaft going down process, keep two distances between shaft, two shafts are kept vertically.
As improving again, air nozzle is the air nozzle closing up in exit, and like this, pressure-air is from the process of air nozzle closing in ejection, and cross section of fluid channel is long-pending to be dwindled to some extent, pressure-air flow velocity is further accelerated, thereby further increased spray pressure.
As further improvement, each whitewashing mouth is with to be linked in air nozzle outside this whitewashing mouth concentric, and like this, the pressurized effect that air pressure sprays slurries is better.
