Abstract
The utility model discloses a novel stake of reinforced concrete spiral, the ground wire pile comprises a pile body, the pile body bottom is provided with conical pile head, the top of pile body is provided with the connecting piece, be provided with the screw thread on the avris of pile body. The utility model discloses the spiral stake is because of lever principle to pile body center be the fulcrum, and screw thread lateral wall and stake point be power, rotatoryly inserts the ground, and inserts the back because its thread face and ground contact, and the production withdrawal resistance strengthens the closely knit degree of ground.
Description
Technical field
This utility model relates to a kind of Novel reinforced concrete screw pile.
Background technology
Along with people use the development and the progress of Building technology required, heavy duty industrial building, high level or super to building
High-rise civil building and public building increase increasingly, and the load of building is increasing, when subsoil can not meet
When supporting upper load and control building deformation, it is necessary to ground is carried out consolidation process, namely building is bearing in people
On the ground that work processed, this ground is referred to as artificial foundation.
Stiffening basic ground mode typically now is changed and is filled out Sand-gravel-cushion Technioue, heavy-tamping method, Sand Pile Method, rammed concrete pile
Method, CFG method, Lime Flyash Pile Method, lime-soil compaction pile method and pile foundation method etc..I mainly introduces stake
Lex fundamentalis.In pile foundation method, one of which is to squeeze into precast concrete pile, and present domestic general employing barrette and triangle cut
Face stake, these two kinds of pile driving construction efficiency are higher, and the engineering time is shorter, more apparent to ground consolidation effect.But yet suffer from squeezing into
Difficulty is there is, the defect that withdrawal resistance is not sufficiently effective during pile driving construction.
Utility model content
The technical problems to be solved in the utility model is the defect overcoming prior art, it is provided that a kind of Novel reinforced concrete
Screw pile, simple and fast, is effectively rotatably inserted in ground rapidly, and with this consolidated subsoil degree of compaction, the method is convenient and simple, construction
Difficulty is low, and the engineering time is short and effective, is greatly accelerated construction speed, effectively solves site foundation construction practical problem.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
This utility model one Novel reinforced concrete screw pile, including pile body, is provided with cone bottom described pile body
Pile crown, the top of described pile body is provided with connector, the avris of described pile body is provided with screw thread.
Further, described screw thread be the first angle outside the screw thread of triangle, and described screw thread be 45 °.
Further, the second angle that described screw thread and horizontal plane are formed is 75 °.
This utility model is reached to provide the benefit that: screw pile is because of lever principle, with pile body center as fulcrum, whorl side
Wall and pile top are power, are rotatably inserted in ground, and contact with ground due to its flank after insertion, produce withdrawal resistance, strengthen
The degree of compaction of ground.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes a part for description, with this practicality
Novel embodiment is used for explaining this utility model together, is not intended that restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
The schematic top plan view that Fig. 2 is；
In figure: 1, pile body；2, screw thread；3, connector；4, pile crown；5, the first angle；6, the second angle.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is illustrated, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain this utility model, being not used to limit this utility model.
Embodiment 1
As shown in Figure 1-2, a kind of Novel reinforced concrete screw pile, including pile body 1, bottom described pile body 1, it is provided with circle
The pile crown 4 of taper, the top of described pile body 1 is provided with connector 3, the avris of described pile body 1 is provided with screw thread 2.
Described screw thread 2 is the screw thread 2 of triangle, and the first angle outside described screw thread 2 is 45 °.
The second angle 6 that described screw thread 2 and horizontal plane are formed is 75 °.
This utility model is for difficulty of construction and consolidation effect, makes a kind of Novel reinforced concrete screw pile, this stake
Body 1 is Reinforced Concrete Circular Cylinder body structure, is with outward one layer of screw thread 2, during special foundation strengthening construction, utilizes electronic beating
Stake machine, by lever law, simple and fast, is effectively rotatably inserted in ground rapidly, with this consolidated subsoil degree of compaction, the method
Convenient and simple, difficulty of construction is low, and the engineering time is short and effective, is greatly accelerated construction speed, effectively solves site foundation construction
Practical problem.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this
Utility model, although being described in detail this utility model with reference to previous embodiment, for those skilled in the art
For, the technical scheme described in foregoing embodiments still can be modified by it, or to wherein portion of techniques feature
Carry out equivalent.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
