Abstract
The utility model relates to a bidirectional cement soil mixing pile head, which structurally fixedly connecting the upper end of a frame support with an external drill rod, jacketing the lower end of the frame support on an external drill rod, wherein external blades fixedly connected from external to internal in the frame support are axially staggered with internal blades which are fixedly connected with an internal drill rod in the frame support, and the rotating direction of the external blades is opposite to that of the internal blades. The bidirectional cement soil mixing pile head overcomes the shortcomings of easily pasting drill caused by identical rotating direction of blades of two adjacent layers of a single layer bit, labor and material consumption resulting from elevating drill rods up and down to mix repeatedly and hard control quality in the prior art. By simultaneous forward and reverse rotation of the internal drill rod, the external drill rod jacketed on the internal drill rod and the frame support, the internal drill rod, the internal blades and external blades on the external drill rod are driven to rotate forwardly and reversely, and the internal blades and external blades adequately mix cement and soil while cutting force is intensified, thereby radically resolving the problems of mud pasting and drill pasting.
Description
Technical field
The utility model relates to a kind of drill bit, particularly a kind of bi-directional cement soil mixing pile head.
Background technology
Before the present utility model, in the cement mixing method base construction of Soft Ground, the drill bit that adopts is individual layer, always there is the blade of adjacent two layers to rotate in the same way, and in work progress, this rotating blades in the same way just is difficult to guarantee that it stirs, and easily sticks with paste and bore, and makes that soil layer rotates with blade in the pile body; In order to overcome this phenomenon, usually adopt and promote the way that drilling rod stirs repeatedly up and down, stir sufficient purpose to reach it, the expense of consequently taking a lot of work material, and difficult quality control.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, develops a kind of forced action type bi-directional cement soil mixing pile head.
The technical solution of the utility model is:
Forced action type bi-directional cement soil mixing pile head, its major technique is characterised in that on the fixedly connected drilling rod outside in frame support upper end, the lower end is enclosed within on the interior drilling rod, the fixedly connected outer leafs of ecto-entad in the frame support, with in frame support, be fixedly connected in intra vane on the drilling rod be axially and stagger, the direction that outer leafs is rotated is opposite with intra vane.
Advantage of the present utility model and effect are embodied in the pile foundation construction process, by interior drilling rod be enclosed within the outer outer drilling rod of drilling rod and frame support the time just, reverse rotation, drilling rod in driving, intra vane on the outer drilling rod, outer leafs is forward and reverse rotation simultaneously also, when drilling rod drives its intra vane rotation promptly, outer drilling rod rotates by the outer leafs that frame support drives on it, just realize, oppositely rotation simultaneously, make intra vane, outer leafs makes in the cement (or curing compound) and the soil body when increasing cutting force and reaches abundant stirring, bores phenomenon thereby thoroughly solve the paste clay coating.
The utility model be applicable to adopt drilling rod rotate construction as engineerings such as soil bolt, deep-mixed pile, powder spray piling, grouting piles.
Because application of the present utility model makes the stirring of pile body cement-soil abundant, thereby improve the speed of construction, in the unit interval, saved cost.To carrying out the high viscosity soil stratum of mixing pile construction in the past, also can construct simultaneously, widen application with the method.
The utility model adopts the interior drilling rod of method control of machinery, outer drilling rod to rotate in opposite directions, thereby reaches well-beaten purpose, so operation is very reliable, easy, this is very important for field construction, and its cost of manufacture is very low, is easy to promote, popularize.Description of drawings illustrates with the drill bit of single frame support
Description of drawings
Fig. 1---the utility model structural principle schematic diagram.
The specific embodiment
As shown in Figure 1, the fixing intra vane 5 in the both sides, lower end of interior drilling rod 1, the fixing frame support 3 in the both sides, lower end of drilling rod 2 outside, in frame support 3 inboard fixedly outer leafs 4, outer leafs 4 directions are ecto-entads; For gaining in strength, outer leafs 4 ends on the frame support 3 are provided with the reinforcing ring 6 of tubulose, and this reinforcing ring 6 is one with outer leafs 4.
When using the utility model, when being site operation, under the guiding of guiding awl 8, intra vane 5 drives by interior drilling rod 1 and creeps into, outer leafs 4 drives by the frame support on the outer drilling rod 23 and creeps into, interior drilling rod 1 and outer drilling rod 2 all can forward and reversely rotate, and remaining inside and outside drilling rod during operation is the rightabout rotation; When cement paste (or curing compound) is whitewashed by mouth spray 7, in being fixed on the drilling rod 1 and frame support 3 in the cement-soil and the soil body between adjacent two intra vanes 5 cut by the opposite direction of outer leafs 4, thereby reach abundant stirring purpose, guaranteed mixing quality, because of stirring thoroughly, solved paste common between adjacent two intra vanes 5 simultaneously and bored phenomenon.
A plurality of intra vanes 5 in frame support 3, a plurality of outer leafs 4 are formed intra vane group, outer leafs group respectively.
Also have intra vane 5 in the lower end of interior drilling rod 1, but outside frame support 3, further help to eliminate to stick with paste and bore phenomenon.
Principle of the present utility model can be applied to other and be similar to the described situation of this example.
Claims (6)
