In the case of inconsistent, can cause Pseudobulbus Bletillae (Rhizoma Bletillae) in soil because of each position discontinuity, make Pseudobulbus Bletillae (Rhizoma Bletillae) stably be deteriorated.
The content of the invention
The purpose of this utility model is exactly to overcome the deficiencies in the prior art, there is provided one kind is by compartment of terrain on steel pipe
Helical blade is set and is changed the size of helical blade each layering of each position of Pseudobulbus Bletillae (Rhizoma Bletillae) in soil is suffered to be held to reach
Uniformity is carried, the performance and the load formula Pseudobulbus Bletillae (Rhizoma Bletillae) in life-span of Pseudobulbus Bletillae (Rhizoma Bletillae) is improved.
To reach above-mentioned purpose, the utility model is employed the following technical solutions：
It is a kind of to carry formula Pseudobulbus Bletillae (Rhizoma Bletillae), steel pipe is provided with, the front end of steel pipe is provided with conic drill, and steel pipe rear end is provided with and ground base
The blue disk that plinth is connected, it is characterised in that drill bit helical blade is welded with conic drill, compartment of terrain is welded with stake on steel pipe
Between each pile body helical blade set in the spacing and pile body of body helical blade set, drill bit helical blade and pile body helical blade set
Away from the integral multiple for drill bit helical blade pitch, the external diameter of drill bit helical blade and every group of pile body helical-blade increases successively from the bottom to top
Ambassador's drill bit helical blade and every group of pile body helical-blade are in back taper mesa-shaped.
The flight pitch of pile body helical blade set described in the utility model is identical with drill bit helical blade pitch, makes brill
Head synchronously pierces soil with pile body.
The flight pitch of pile body helical blade set described in the utility model is the integral multiple of drill bit helical blade pitch,
To reduce the resistance of drill bit, the purpose of quick lathe turner is reached.
The taper angle of pile body helical blade described in the utility model is identical with the taper angle of drill bit helical blade, taper angle
For 20-50 ° so that every helical blade of pile body helical blade uniform force in soil layering.
The taper angle of pile body helical blade set described in the utility model is 40, so that the bearing power increase of pile body, increases
The stability of pile body, the taper angle of drill bit helical blade is 33, to reduce soil resistance, reaches the purpose of quick lathe turner.
The utility model is particularly well-suited in the soil of layering, and particularly per layer of packing gradually increases from shallow to deep
Greatly, the uniform entirety to Pseudobulbus Bletillae (Rhizoma Bletillae) of carrying of the every helical blade of Pseudobulbus Bletillae (Rhizoma Bletillae) in soil is can reach, Pseudobulbus Bletillae (Rhizoma Bletillae) is improve and is existed
Stability and service life in soil, eliminates Pseudobulbus Bletillae (Rhizoma Bletillae) because of the uneven caused sinking of stand under load, unstable etc. in soil layer
Phenomenon.
Description of the drawings
Fig. 1 is a kind of enforcement state diagram of the present utility model.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in the figure：It is a kind of to carry formula Pseudobulbus Bletillae (Rhizoma Bletillae), steel pipe 1 is provided with, the front end of steel pipe 1 is provided with conic drill 2, after steel pipe 1
End is provided with the blue disk 3 being connected with ground base, the structure and the interconnected relationship between them of above-mentioned each part
Same as the prior art, this is not repeated, of the present utility model to be characterised by being welded with drill bit helical blade 4, steel on conic drill 2
Compartment of terrain is welded with spacing H and pile body of pile body helical blade set 5, drill bit helical blade 4 and pile body helical blade set 5 on pipe 1
On each pile body helical blade set spacing L for the pitch of drill bit helical blade 4 integral multiple, drill bit helical blade 4 and per pile body
The external diameter of helical blade set 5 increases successively from the bottom to top, makes drill bit helical blade 4 and per pile body helical blade set 5 in inversed taper platform
Shape, the flight pitch of described pile body helical blade set is identical with drill bit helical blade pitch, makes drill bit brill synchronous with pile body
Enter soil, the flight pitch of described pile body helical blade set can also be the integral multiple of drill bit helical blade pitch, to subtract
The resistance of few drill bit, reaches the purpose of quick lathe turner.In addition, the taper angle and brill of pile body helical blade described in the utility model
The taper angle of head helical blade is identical, and taper angle is 20-50 ° so that every helical blade of pile body helical blade is layered in soil
Middle uniform force, particularly when the taper angle of described pile body helical blade set is 40, the taper angle of drill bit helical blade is 33
When, the bearing power increase of pile body, the stability of pile body increases, and pierces soil resistance, reaches the purpose of quick lathe turner, above-mentioned
The lower end of steel pipe 1 is provided with conic drill 2, to facilitate Pseudobulbus Bletillae (Rhizoma Bletillae) quick drill to enter figure layer, the method that upper end is connected with ground installation foundation
Blue 3, the external diameter of steel pipe 1, wall thickness, length are needed according to requirements and the condition such as construction geology determines, the stake of the same uniform pitch
The compartment of terrain of body helical blade set 5 is welded on steel pipe 1, and drill bit helical blade is welded on conic drill 2, so that conic drill is more
It is easy to early stage and pierces soil layer, pile body helical blade improves the performance for carrying formula Pseudobulbus Bletillae (Rhizoma Bletillae), the pile body helical blade of uniform pitch
When component, drill bit helical blade 4 make whole pile body screw in underground, the unified track of every helical blade peace screws in underground, prevent by
Soil layer is unscrewed, and destroys soil layer, and the internal diameter of pile body helical blade 4 is identical with diameter of steel tube, and external diameter increases one by one from the bottom to top, convenient
Pseudobulbus Bletillae (Rhizoma Bletillae) enters after underground layer, and the soil layer packing that the helical blade of various outer diameter is in is also different, the less helical blade of external diameter
In the of a relatively high soil layer of packing, the larger helical blade of external diameter makes Pseudobulbus Bletillae (Rhizoma Bletillae) in the relatively low soil layer of packing
Uniform stand under load is reached, keeps the carrying of every helical blade be close to identical, allow Pseudobulbus Bletillae (Rhizoma Bletillae) main body more to consolidate, expand Pseudobulbus Bletillae (Rhizoma Bletillae)
Performance and use range, effectively solve plain edition Pseudobulbus Bletillae (Rhizoma Bletillae) with soil layer, and the discrepant soil property of packing
It is middle the phenomenons such as sinking occur.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from the utility model know-why, some improvement and modification can also be made, these change
Enter and also should be regarded as protection domain of the present utility model with modification.
