Description
Technical field
The utility model relates to water construction basic field, particularly relates to a kind of hydraulic architecture foundation pile structure.
Background technology
In the pile foundation engineering of the current water conservancy and hydropower high in requirement for bearing capacity building, concrete tubular pile occupies critical role.Water conservancy and hydropower building can be subject to the impact of current usually; pile foundation must can bear larger radial load; and the profile of conventional concrete pile tube is generally straight smooth type; frictional force between this pile tube and the soil body is less; the binding force that the soil body provides pile pipe and support force more weak, for the supporting capacity improving its radial direction need increase the diameter of pile pipe usually, and during the larger bearing capacity of demand fulfillment; often need the length or the quantity that increase pile tube, this all can increase the cost of whole pile foundation engineering.
Notification number be CN102493439 A patent discloses a kind of building foundation pile element, it is made up of three stage structure, epimere is the round stake of being made up of concrete, stage casing adopts steel pipe, steel pipe side is provided with some inclined side stake holes, arrange close-fitting side stake with it in the stake holes of side, hypomere is precast pile; Described hypomere overlaps mutually with stage casing, then is connected with the precast pile anchoring of hypomere by the steel pipe in stage casing by upper Cast-in-place concrete base, 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, adds the contact area between itself and the soil body, improve between the two suit power and frictional force, improve pile body supporting capacity.But due to the existence of side stake, need to provide larger pressure at right angle when carrying out piling construction, add difficulty of construction, and when side stake is descending, destruction is formed to soil structures, reduce the restraint forces of the soil body to pile body.
Notification number be CN100408759C patent 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, being equipped with in pin-and-hole can outward extending stake pin, stake pin is ejected pile lining by inclined-plane one by one that execute utilization of hour spiral stem stem lower end, plays thus and improves the object that pile pipe sidewall and the soil body agree with power.But because stake pin adopts slidably mode to be placed in pile pipe, both positions are not relatively fix, connect firm not, therefore the support fixation of stake pin to pile pipe is not remarkable.
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 greatly, improve the hydraulic architecture foundation pile structure of pile body stability and supporting capacity greatly in construction.
For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of hydraulic architecture foundation pile structure, 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 piercing 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 most advanced and sophisticated; The lumen wall of described pile pipe upper end is provided with a wear-resistant seal cover, and the lateral wall of described wear-resistant seal cover is fixedly connected with pile pipe, and its inside wall and core bar are tightly slidably matched; Described pile pipe is made up of more piece grafting.
When the utility model uses, pile pipe is driven underground section by section, concrete perfusion in the tube chamber of pile pipe, after the tube chamber filling pile pipe, the lower end of core bar is inserted in tube chamber, and exert pressure core bar is moved down, because tube chamber upper end is sealed by wear-resistant seal cover, concrete when core bar moves down in pile pipe is subject to high-pressure extrusion and outwards flows out from the side opening of pile pipe, until core bar arrives the bottom of tube chamber, 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 extended outward, concrete in diagonal brace wing and pile pipe is structure as a whole, outward extending diagonal brace wing adds the contact area of pile pipe and the soil body, improve both adhesions.
The utility model has following beneficial effect: after it has been constructed, and pile pipe sidewall forms irregular outward extending diagonal brace wing, and these diagonal brace wings can be the support force that pile pipe provides axial and radial, improves stability and the load of pile pipe; During construction, implement extruding and form diagonal brace wing by core bar to concrete, pressure is large, easily implements.The utility model structure is simple, and construct fairly simple, convenient, the piling strtucture after final molding is stablized, and cost is lower, large with the adhesion of the soil body, overall bearing and excellent in stability.
