Abstract

The utility model relates to a kind of PHC tubular pile connecting structure, comprises lower PHC pile tube, upper PHC pile tube and jointing, and described lower PHC pile tube and upper PHC pile tube are shoulder hole structure, and described PHC pipe pile end portion aperture is greater than inner aperture; Described jointing is seamless steel pipe, and jointing outer circumference surface is provided with location annular recess; Described location annular recess is arranged on jointing axially middle part.The utility model PHC tubular pile connecting structure, structure is simple, and jointing is arranged on pile tube one end together with end plate before PHC pile tube is built, and jointing axis and pile body axis keep vertical.Stake machine elevator is utilized another root PHC pile tube non junction one end to be inserted the PHC pipe pile joint having sunk to the soil body, then the end plate at PHC pile tube two ends is welded, two PHC pile tubes are linked together, can effectively save stake dislocation deviation up and down and improve joint shear-carrying capacity by control PHC pile tube.

Description

PHC tubular pile connecting structure
Technical field
The utility model relates to a kind of building operations instrument, specifically, relates to a kind of PHC tubular pile connecting structure.
Background technology
At present, most of PHC tubular pile splicing adopts pile end board to be directly welded to connect.The defect that the method exists is: save stake dislocation deviation up and down large; in extreme terrain, PHC pipe pile joint place shear resistant capacity is low.
Utility model content
For above-mentioned deficiency of the prior art, the utility model provides a kind of structure simple, reduces pile tube and saves stake dislocation deviation up and down, improve the PHC tubular pile connecting structure of joint shear-carrying capacity.
Technical solution adopted in the utility model is:
A kind of PHC tubular pile connecting structure, comprise lower PHC pile tube, upper PHC pile tube and jointing, described lower PHC pile tube and upper PHC pile tube are shoulder hole structure, and described PHC pipe pile end portion aperture is greater than inner aperture; Described jointing is seamless steel pipe, and jointing outer circumference surface is provided with location annular recess; Described location annular recess is arranged on jointing axially middle part.
Described location ring-type recess width is 1-2 millimeter, and the degree of depth is 1-2 millimeter.
Aperture, described end is greater than inner aperture 2-3 millimeter.
The described end hole degree of depth is 200-250 millimeter; The described joint length that connects is 180-195 millimeter.
The beneficial effect of the utility model hinge structure:
The utility model PHC tubular pile connecting structure, structure is simple, and jointing is arranged on pile tube one end together with end plate before PHC pile tube is built, and jointing axis and pile body axis keep vertical.Stake machine elevator is utilized another root PHC pile tube non junction one end to be inserted the PHC pipe pile joint having sunk to the soil body, then the end plate at PHC pile tube two ends is welded, two PHC pile tubes are linked together, can effectively save stake dislocation deviation up and down and improve joint shear-carrying capacity by control PHC pile tube.

Detailed description of the invention
Referring to drawings and Examples, the utility model is described in detail:
Accompanying drawing 1-4 is known, a kind of PHC tubular pile connecting structure, comprises lower PHC pile tube 1, upper PHC pile tube 2 and jointing 3, and described lower PHC pile tube 1 and upper PHC pile tube 2 are shoulder hole structure, and described PHC pipe pile end portion aperture 4 is greater than inner aperture 5; Described jointing 3 is seamless steel pipe, and jointing 3 outer circumference surface is provided with location annular recess 6; Described location annular recess 6 is arranged on jointing axially middle part.
Described location ring-type recess width is 1-2 millimeter, and the degree of depth is 1-2 millimeter.
Aperture, described end is greater than inner aperture 2-3 millimeter.
The described end hole degree of depth is 200-250 millimeter; The described joint length that connects is 180-195 millimeter.
During the construction of the utility model PHC tubular pile connecting structure, jointing is arranged on pile tube one end together with end plate before PHC pile tube is built, and jointing axis and pile body axis keep vertical.Joint adopts seamless steel pipe, wall thickness 10mm.During PHC pile tube pile sinking, after first segment PHC pile tube sinks to, the 500mm that bassets is held in stake, stake machine elevator is utilized another root PHC pile tube non junction one end to be inserted the PHC pipe pile joint having sunk to the soil body, then the end plate at PHC pile tube two ends is welded, two PHC pile tubes are linked together, can effectively save stake dislocation deviation up and down and improve joint shear-carrying capacity by control PHC pile tube.
