Abstract
The utility model discloses an anti -floating pile base structure, including round platform shape pile body, annular floor and bucket formula structure. Round platform shape pile body down increases on its cross sectional area follow in proper order. The surface is provided with the mat surface of increase frictional force. Arrange annular floor in that the below of round platform shape stake is even symmetrically. Annular floor constitute by the sector of a plurality of symmetries. Each sector's size of a dimension equals to all leave mutually unidimensional recess between every sector. Bucket formula structure, the surface is provided with the mat surface of increase frictional force, the bucket wall is inboard to adopt the circular arc transition with barrel head inboard junction. The utility model discloses a pile body lateral wall has symmetrical evenly distributed's annular floor to produce interlocking and interlock effect with the soil body on every side, and the application of bucket formula structure has improved stake bearing capacity and frictional resistance physically by a wide margin. On the other hand, pile body lateral wall are the round platform structure, and the round platform lateral wall has born the gravity stress of the partial soil body, have increased the frictional force between the round platform and the soil body, have strengthened the resistance to plucking performance of pile body.
Description
Technical field
This utility model relates to field of civil engineering, and specifically, this utility model relates to a kind of antitorque piling strtucture of resistance to plucking。
Background technology
Along with socioeconomic fast development, the application of uplift pile is also more and more extensive, has transmission line tower foundation, wind-power electricity generation single-pile foundation etc.。Particularly the pile foundation of marine structures to bear very big vertical load, horizontal loading and tilting moment load, load-bearing complicated condition。Under spatial load effect, pile body rotates, and action zone pile body separates with the soil body, produces crack。So the resistance to plucking anti-twisting property for pile foundation is had higher requirement, and the rheobasic raising of stake is typically via the diameter increasing pile foundation, but the increase of Pile Diameter can bring about a lot of problem。Waste construction material on the one hand, on the other hand construction equipment and construction technology be it is also proposed higher requirement。Extend the engineering construction cycle, reduce construction quality。
Therefore, there has been very great meaning for studying a kind of antitorque structure of novel resistance to plucking。
Summary of the invention
To be solved in the utility model is the not high enough technical problem of current bearing capacity of single pile, it is provided that a kind of antitorque piling strtucture of resistance to plucking。
In order to solve the problem existing for current single pile, this utility model is achieved by following technical scheme。
The antitorque structure of a kind of resistance to plucking includes the floor of a pile body and sidewall thereof。
Pile body mentioned above is by the bearing plate on top, the frustum cone structure at middle part, and the pile top of bottom is constituted。
Bearing plate mentioned above, generally circular in shape, area is between the end face and base area of round platform。
Round platform mentioned above, diameter becomes big from top to bottom successively。
Pile top mentioned above, is shaped as circular cone, and diameter is sequentially reduced from top to bottom。
Floor mentioned above, is shaped as relatively thin triangular prism, equal in magnitude。Being distributed in round platform sidewall symmetrically and evenly along pile body axis direction, single floor size is first sequentially reduced from top to bottom, and floor outer rim is vertical with the bottom edge of round platform and is on same vertical axis。
All there is the matsurface of increasing friction force on round platform mentioned above and floor surface。
Compared with existing technique effect, the beneficial effects of the utility model are, the middle part of described pile body is frustum cone structure, round platform sidewall bears the weight stress of the part soil body, increase the friction between round platform and the soil body, enhance the extraction-resistant behavior of pile body, simultaneously conical bottom pile body, make piling convenience and high-efficiency, reduce operating expenses。
The area of pile body bearing plate is between the end face and base area of frustum cone structure, it is to avoid produces stress concentration phenomenon on bearing plate and the contact surface of building, has influence on the stability of building。
Whole pile body is placed in soil layer, and the floor of round platform sidewall produces interlocking and interlocking with surrounding soil, bearing capacity and the frictional resistance of pile body is greatly improved, enhances the torsional property of pile body。
Round platform and floor surface configuration have the matsurface of increasing friction force, will further improve resistance to plucking and the resistance to torsion of pile body。
This utility model also has, simple in construction, easy to operate, saves material, it is simple to the advantage promoted the use of。
