Abstract
The utility model discloses a kind of building foundation pile element, it comprises pile pipe and core bar, and pile pipe is column casing shape, and lower end is provided with tip, and the sidewall of pile pipe is evenly equipped with some side openings that pierce pile pipe tube wall, and the outboard end of side opening is lower than medial extremity; Core bar can insert in the tube chamber of pile pipe, and the lower end of core bar is provided with plunger, and plunger outer wall is provided with abrasive rubber layer.When it uses, pile pipe is driven underground section by section, to concrete perfusion in the tube chamber of pile pipe, the lower end of core bar is inserted in tube chamber, and exert pressure core bar is moved down, concrete is subject to high-pressure extrusion and outwards flows out from side opening, in the annular housing forming between core bar and pile pipe, inject concrete again, after final concrete setting, core bar is firmly secured in pile pipe, and in side opening, is provided with the diagonal brace wing extending outward.The utility model is simple in structure, constructs fairly simple, convenient, and the piling strtucture after final molding is stable, and cost is lower, large with the adhesion of the soil body, overall bearing and excellent in stability.
Description
Technical field
The utility model relates to building foundation field, relates in particular to a kind of building foundation pile element.
Background technology
At present for the pile foundation engineering of highrise building and the high building lot of requirement for bearing capacity, concrete tubular pile occupies critical role, the profile of traditional concrete tubular pile is generally straight line smooth type, the shortcoming of this pile tube is that the frictional force between the soil body is less, in the time that needs meet larger bearing capacity, the length or the quantity that often need to increase pile tube, this can increase the cost of whole pile foundation engineering.
Notification number is that the patent of CN102493439 A discloses a kind of building foundation pile element, it is made up of three stage structure, epimere is the circle stake of being made up of concrete, stage casing adopts steel pipe, steel pipe side is provided with some inclined side stakes hole, close-fitting side stake is with it set in side stake hole, and hypomere is precast pile; Described hypomere overlaps mutually with stage casing, then by upper Cast-in-place concrete base, the steel pipe in stage casing is connected with the precast pile anchoring of hypomere, and the precast pile lower end of hypomere is provided with lower Cast-in-place concrete base.Due to the existence of side stake, oblique cutting, between the soil body, has increased the contact area between itself and the soil body, improved between the two suit power and frictional force, improved pile body supporting capacity.But due to the existence of side stake, while carrying out piling construction, need to provide larger pressure at right angle, increase difficulty of construction, and side stake forms and destroy soil structures when descending, reduced the restraint forces of the soil body to pile body.
Notification number is that the patent of CN100408759C discloses a kind of longitudinally inserted horizontally wedged construction pile and construction method thereof, it comprises hollow pile pipe, it is characterized in that: the sidewall of pile pipe is provided with pin-and-hole, in pin-and-hole, be equipped with and can outward extending stake sell, the inclined-plane of executing utilization of hour spiral stem stem lower end ejects pile lining by stake pin one by one, plays thus the object that improves pile pipe sidewall and the soil body and agree with power.But, be placed in pile pipe because stake pin adopts slidably mode, both positions are not relatively to fix, connect firm not, therefore stake pin is not remarkable to the support fixation of pile pipe.
Utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of scientific structure design, and more for convenience, pile body sidewall and peripheral soil active force are large, greatly improve the building foundation pile element of pile body stability and supporting capacity in construction.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of building foundation pile element, it is characterized in that: it comprises pile pipe and core bar, described pile pipe is column casing shape, lower end is provided with tip, the tube chamber lower end closed of pile pipe, the sidewall of pile pipe is evenly equipped with some side openings that pierce pile pipe tube wall, and the outboard end of described side opening is lower than medial extremity; Described core bar can insert in the tube chamber of pile pipe, and core bar outer wall and pile pipe inwall form an annular housing, and the lower end of core bar is provided with plunger, and described plunger outer wall is provided with abrasive rubber layer; Described pile pipe is pegged graft and is formed by more piece.
When the utility model uses, pile pipe is driven underground section by section, to concrete perfusion in the tube chamber of pile pipe, after filling the tube chamber of pile pipe, the lower end of core bar is inserted in tube chamber, and exert pressure core bar is moved down, concrete when core bar and plunger move down in pile pipe is subject to high-pressure extrusion and outwards flows out from the side opening of pile pipe, treat that plunger arrives the bottom of tube chamber, then in the annular housing forming between core bar and pile pipe, inject concrete, after final concrete setting, core bar is positioned at pile pipe, pass through Concrete Filled between the two, connect, firmly, and in side opening, be provided with the diagonal brace wing extending outward, concrete in diagonal brace wing and pile pipe is structure as a whole, outward extending diagonal brace wing has increased the contact area of pile foundation and the soil body, both adhesions are improved.
The utlity model has following beneficial effect: after its construction completes, pile pipe sidewall forms irregular outward extending diagonal brace wing, and these diagonal brace wings can be pile pipe support force axially and is radially provided, and have improved stability and the load of pile pipe; When construction, by core bar, plunger, concrete is implemented to extruding and form diagonal brace wing, pressure is large, easily implement, and when entering bottommost, plunger the concrete of perfusion before all can be pressed in side opening, and filler can be continued in space between stem stem and pile pipe, has greatly improved concrete groundwater increment, has improved load and the stability of pile foundation.The utility model is simple in structure, constructs fairly simple, convenient, and the piling strtucture after final molding is stable, and cost is lower, large with the adhesion of the soil body, overall bearing and excellent in stability.
