The utility model uses the form of pore-forming pile pipe and pore-forming pile top structure Split assembled, provides a kind of structure letter
It is single, easy for construction, low in cost, the same pore-forming and pile follower for being applied to different designs stake diameter at pore structure can be used, also overcomed
When tube drawing because soil supporting course rubs it is excessive due to be easily damaged the multiple aperture static press piling of pile pipe into pore structure.
The utility model is described further below in conjunction with attached drawing.
Referring to Fig.1 shown in -4, by existing hydraulic static pile pressing machine, multiple aperture static press piling is installed on liquid at pore structure
In the pile clamping box for pressing static pile press, foundation pile is sent to design position or reaches depth of pore forming by the active force downward by static pressure machine
Design position；A kind of multiple aperture static press piling including pore-forming pile pipe 1 and is fixedly connected on 1 bottom of pore-forming pile pipe at pore structure
Pore-forming pile top structure, wherein pore-forming pile top structure includes two semicircle guiding pile tops 4 being plugged in together, two direction pegs
Point 4 is rotatablely connected by bolt 5, and vertical connector 3 is radially connected on bolt 5, is welded in the other end of vertical connector 3
It is connected to the crossbeam rod piece 2 axially vertical with it；Two connectors 6, bolt are welded with along the both ends of basal diameter in pore-forming pile pipe 1
5 both ends are connect with two connectors 6 respectively.
The angles of two guiding pile tops 4 are θ, and angular range is 60 °≤θ≤180 °, the purpose being arranged in this way be in order to
When piling, two guiding pile tops 4 can separate automatically during pushing, play guiding, broken rock and intermal force；Two halves when pile pulling
Circle guiding pile top 4 merges automatically, so that 1 inner cavity of pore-forming pile pipe is in communication with the outside, because soil supporting course is rubbed when overcoming tube drawing
The drawbacks of being easily damaged pile pipe greatly.
Crossbeam rod piece 2 is welded on the inner wall of pore-forming pile pipe 1, bottom surface of the welding position apart from the pore-forming pile pipe 1
350mm-450mm, wherein optimal is the bottom surface 400mm for selecting welding position apart from the pore-forming pile pipe 1, correspondingly vertical connection
The distance of length cooperation the crossbeam rod piece 2 and bolt 5 of part 3.
Wherein, vertical connector 3 is connected to the middle part of bolt 5, it is ensured that in the process that static press piling is pushed and extracted
Middle stability under loading.
It is oriented to pile top 4 and is equipped with sizes when designing the aperture different variations of generation, various sizes of guiding can be replaced
Pile top 4, to realize the same pore-forming and pile follower for being applied to different designs stake diameter at pore structure.
Pore-forming pile pipe 1 is made of the steel material of Du≤1/1000 Wan Qu, and bending strength refers to material in bend loading
The maximum stress that ruptures under effect or can be born when reaching regulation moment of flexure, maximum (normal) stress when this stress is bending, with MPa
(megapascal) is unit, it reflects the resistant to bending ability of material, for measuring the bending property of material.
In conclusion pore-forming pile pipe 1 and pore-forming pile top structure form not only fixation but also a movable organic whole, work as design
When aperture becomes larger, it only replacement guiding pile top can meet drilling construction requirement, save expense and cost to enterprise, have
The features such as structure is simple, easy for construction, low in cost.
