Yet this drilling expanding pallet pile structure and constructing operation are all comparatively complicated, and because stake pipe perisporium is offered wall groove and groove, so the intensity of pile body self weakens to some extent.
Summary of the invention
The present invention wants the technical solution problem to be: at the shortcoming of above prior art existence, propose a kind of except that the vertical direction side friction, also have a longitudinally inserted horizontally wedged construction pile of horizontal direction wedging function, thereby significantly improve the solid steadiness of building stake, and this stake should structure comparatively simple, easy construction, the present invention simultaneously also will provide corresponding construction method.
In order to solve above technical problem, longitudinally inserted horizontally wedged construction pile of the present invention comprises hollow stake pipe, one end of described stake pipe is equipped with the taper pile crown, and its improvements are: the sidewall of described stake pipe is shaped on pin-and-hole, and being equipped with in the described pin-and-hole can outward extending stake pin.
Basic job practices of the present invention may further comprise the steps:
1), pile crown is downward, contracts in the stake pin, and the stake pipe vertically is pressed into ground;
2), treat that stake pipe is in place after, the stake pin is laterally ejected from inside to outside.
This shows that before the construction, pile lining is not stretched out in stake pin outer end, therefore can be pressed into foundation soil by static pressure equipment as common prestressing pipe pile construction, finishes vertical inserting.Afterwards, from the centre bore of stake pipe, the stake pin is outwards ejected, finish transverse wedge.Finally, the stake of whole building is embedded in underground just as wolf pressure bar shape, and not only has vertical termination bearing capacity and the side friction that produces of inserting between the foundation soil, and exist since transverse wedge produce agree with power.This agrees with power not only can produce the resistance to plucking active force more much bigger than side friction, and the supporting capacity of building stake is also increased substantially.And it is simple in structure, and easy construction is little, easy to utilize to the influence of stake pipe self intensity.
