Abstract
The utility model discloses a novel triaxial stirring stake device, respectively stir drilling rod pivoted actuating mechanism, each including three stirring drilling rods of arranging side by side and drive stirring drilling rod bottom is connected with stirring head, the left and right sides be formed with slip casting pipeline, centre in the stirring drilling rod be formed with telescopic slip casting pipeline in stirring the drilling rod, this novel triaxial stirring stake device just designs to telescopic slip casting pipeline through forming the slip casting pipeline in the stirring drilling rod in the centre, can effectively increase the diffusion area of thick liquid for the thick liquid is abundant with soil body stirring, thereby the one -tenth stake quality of cement stirring stake reduces the possibility that the seepage takes place.
Description
Technical field
The utility model relates to geotechnical engineering construction equipment technical field, particularly a kind of three axle mixing pile devices.
Background technology
Three axle mixing piles are conventional foundation stabilization piling strtuctures, it utilizes the materials such as cement as curing agent, in ground depths, foundation soil and curing agent are forced to mix by three axle mixing pile machines, foundation soil is hardened into have stake (wall) body of continuity, impermeability and some strength. In recent years, three axle mixing pile machines obtained Rapid Popularization in coastal soft clay area such as China river, Zhejiang, were widely used in base pit engineering and went along with sb. to guard him barricade, passive area reinforcing, water seal curtain.
Three axle mixing pile machines have three stirring drilling rods arranged side by side conventionally, at present, existing three axle mixing pile machines, conventionally only in the stirring drilling rod of both sides, slurry intake channel is set, in middle stirring drilling rod, slurry intake channel is not set and this stirring drilling rod is shorter than the stirring drilling rod of both sides, in addition, the stirring-head length of blade that stirs drilling rod is less than 1/2nd of adjacent stirring drilling rod axle center spacing, make middle part at the bottom of single width three axle mixing pile stakes, not in place at layer of sand and the diffusion of rock stratum intersection slurries, slurries and the soil body stir not in place, pile quality is poor, be prone to percolating water phenomenon.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of effective raising pile quality, ensures the novel three axle mixing pile devices of pile foundation stagnant water effect.
For solving the problems of the technologies described above adopted technical scheme: a kind of novel three axle mixing pile devices, comprise three stirring drilling rods that are arranged in juxtaposition and the driving mechanism that drives each stirring drilling rod to rotate, each described stirring drilling rod bottom is connected with stirring-head, described in the left and right sides, stir in drilling rod and be formed with grouting pipe, in middle described stirring drilling rod, be formed with telescopic grouting pipe.
Further, each described stirring drilling rod is connected and is formed by multistage tube coupling, be interval with vertically some stirring vane groups at each described stirring drilling rod mid portion, staggered separating of stirring vane group on adjacent described stirring drilling rod, each described stirring vane group comprises even spaced apart stirring vane.
Further, each described stirring drilling rod bottom one section of tube coupling be formed with fixed support, described fixed support and the sleeve gasket that is provided with that stirs drilling rod of each stirring drilling rod that is connected and fixed.
Further, each described stirring-head bottom has the injected hole being connected with grouting pipe, and each described stirring-head is along being circumferentially interval with some blades, and each described length of blade is less than adjacent stirring drilling rod axle center spacing.
Beneficial effect: these novel three axle mixing pile devices by forming grouting pipe in middle stirring drilling rod, and be designed to telescopic grouting pipe, can effectively increase the diffusion area of slurries, slurries and the soil body are stirred fully, thereby the pile quality of cement mixing pile, reduces the possibility that seepage occurs.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
With reference to Fig. 1, a kind of novel three axle mixing pile devices of the utility model, comprise three stirring drilling rods that are arranged in juxtaposition 10 and the driving mechanism 30 that drives each stirring drilling rod 10 to rotate, each drilling rod 10 bottoms of stirring are connected with stirring-head 20, in three stirring drilling rods 10, be all formed with grouting pipe 11, each stirring-head 20 bottoms have the injected hole 21 being connected with grouting pipe 11, wherein, grouting pipe 11 in middle stirring drilling rod 10 is telescopic grouting pipe, adopt telescopic grouting pipe, can effectively increase the diffusion area of slurries, slurries and the soil body are stirred fully, ensure the pile quality of cement mixing pile.
In the present embodiment, each drilling rod 10 that stirs is connected and is formed by multistage tube coupling, between every section of tube coupling, adopt pin to connect, each drilling rod 10 mid portions that stir are interval with some stirring vane groups vertically, stirring vane group on adjacent stirring drilling rod 10 should be interlocked and be separated, particularly, stirring vane group on left and right sides stirring drilling rod 10 is in same level, stagger in middle stirring vane group interval of stirring on drilling rod 10, each stirring vane group comprises evenly spaced apart multiple stirring vanes 12.
As preferably, respectively stir drilling rod 10 bottom one section of tube coupling be formed with the fixed support 40 of each stirring drilling rod 10 that is connected and fixed, fixed support 40 with stir drilling rod 10 be provided with sleeve gasket 41.
Each stirring-head 20 is along being circumferentially interval with some blades 22, each blade 22 length are less than adjacent stirring drilling rod 10 axle center spacing, the size of abandoning tradition and version, can fully be uniformly mixed layer of sand and rock stratum intersection slurries and the soil body, improves pile quality.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing at described technical field those of ordinary skill, can also under the prerequisite that does not depart from the utility model aim, make various variations.
