Abstract
The utility model discloses a stirring head of a stirring pile. The stirring head is arranged at the end part of a rotary shaft of the stirring pile and can rotate along with the rotary shaft; the stirring head comprises a mandrel with an axial grout inlet passage; the axial grout inlet passage is communicated with a grout conveying pipeline of the rotary shaft; stirring blades rotating along with the mandrel are fixed outside the mandrel; the mandrel is provided with a guniting pipe communicated with the axial grout inlet passage at the backside surface position of the stirring blades; an axial grout outlet is formed in the front end wall of the guniting pipe; multiple radial grout outlets are formed in the side wall of the guniting pipe. The multiple radial grout outlets are formed in the side wall of the guniting pipe, so cement paste (or lime slurry) can be sprayed from multiple positions and directions in the construction stirring process, stirred soft clay and the cement paste (or the lime slurry) can be uniformly mixed, and the stirring quality is improved.
Description
Technical field
The utility model relates to a kind of stirring-head of in ground deep, cement paste (or lime mortar) and bury being forced to the agitation pile mixing.
Background technology
In building operations, the normal bury deep mixing method adopting is to utilize cement paste (or lime mortar) as curing compound, and by a kind of agitation pile, in ground deep, cement paste (or lime mortar) and bury are forced to mix, the bury finally mixing hardens into column, wall shape or the block reinforcing body with some strength with cement paste (or lime mortar).These reinforcing bodies have good globality, water stability and enough intensity, with natural ground form compound foundation, and shared upper load.
Due in stirring work progress, agitation pile is that the stirring-head rotation by driving its end band paddle is directly stirred pine by bury, and simultaneously by cement paste (or lime mortar) from the mouth spray ejection of stirring-head so that cement paste (or lime mortar) and bury are forced to mix, so stirring-head is the key factor that determines ground stabilization effect in soft sticky deep mixing method.If China Patent No. is the stirring-head of the disclosed agitation pile of patent of invention of " 200510110430X ", though it can force bury and cement paste (or lime mortar) to mix preferably, but because its shotcrete pipe only has a grout outlet that is positioned at rotating vane, only can be towards a direction ejection cement (or ash), in the process stirring in construction, can be subject to being stirred that head stirs pine and the stopping of the bury that rotates with stirring-head from the cement paste (or lime mortar) of this grout outlet ejection, cannot evenly mix with all buries that stirred pine, affect mixing quality.
Summary of the invention
The purpose of this utility model is to provide the one can be better by the stirring-head of bury and the mixed uniformly agitation pile of cement paste (or lime mortar).
The stirring-head of a kind of agitation pile described in the utility model, the end that is arranged on the axis of rotation of agitation pile also can rotate with axis of rotation, comprise the mandrel with axial slurry intake channel, the defeated slurry passage of this axial slurry intake channel and axis of rotation leads to, the outside of mandrel is fixed with the paddle with mandrel rotation, mandrel is provided with in the trailing flank position of paddle the shotcrete pipe leading to axial slurry intake channel, the front bulkhead of shotcrete pipe has axial grout outlet, it is characterized in that: the sidewall of described shotcrete pipe also has multiple radially grout outlets.
The utility model is except being provided with axial grout outlet at the front bulkhead of shotcrete pipe, also have multiple radially grout outlets at the sidewall of shotcrete pipe, in the process that can stir in construction, cement paste (or lime mortar) can be sprayed from multiple positions and direction, making to be stirred loose bury can mix more equably with cement paste (or lime mortar), thereby improves mixing quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of shotcrete pipe.
The specific embodiment
As Fig. 1, shown in Fig. 2, the stirring-head of described a kind of agitation pile, the end that is arranged on the axis of rotation (not shown) of agitation pile also can rotate with axis of rotation, comprise the mandrel 1 with axial slurry intake channel (not shown), the defeated slurry passage (not shown) of this axial slurry intake channel and axis of rotation leads to, there is the paddle 2 rotating with mandrel 1 in the outside of mandrel 1, mandrel 1 is provided with in the position of the trailing flank (side of the contrary rotation direction in paddle) of paddle the shotcrete pipe 3 leading to axial slurry intake channel, the front bulkhead 31 of shotcrete pipe 3 has axial grout outlet 32, the sidewall of described shotcrete pipe 3 also has multiple radially grout outlets 33, thereby in the process stirring in construction, cement paste (or lime mortar) can be sprayed from multiple positions and direction, making to be stirred loose bury can mix more equably with cement paste (or lime mortar), thereby raising mixing quality.
As shown in Figure 2, the spacing between adjacent radially grout outlet 33 is dwindled to its end direction gradually from its root of shotcrete pipe 3, to guarantee that bury can mix more equably with cement paste (or lime mortar).Wherein, the spacing between adjacent radially grout outlet 33 is 5cm to the maximum, and the adjacent radially spacing between grout outlet minimum is 1cm.Radially the diameter of grout outlet 33 is less than the diameter of axial grout outlet 32.
As shown in Figure 1, the length of described shotcrete pipe 3 is greater than the half of the length of paddle 2, but is less than the total length of paddle 2.
The structure that described paddle 2 and mandrel 1 are formed in one, or be weldingly fixed on the lateral surface of mandrel 1.
As shown in Figure 1, the front bulkhead 31 of described shotcrete pipe 3 detachably tightens up (for example passing through screws tighten) on shotcrete pipe 3, so that the inside of shotcrete pipe is cleared up.
