Description
Technical field
The present invention relates to a kind of prefabricated bamboo joint pile and its construction method, belong to technical field of building construction.
Background technology
It is slow borehole speed to be present in the conventional stake of Building Trade in China at present, if supporting course can cause pile body very long more deeply.Mesh
Preceding bored concrete pile system refers to form stake in foundation soil by means such as machine drilling, steel pipe soil compaction or manpower excavations in engineering site
Hole, and steel reinforcement cage, concrete perfusion and the stake made are placed in it, different according to forming hole method, it is heavy that bored concrete pile can be divided into again
Several classes such as pipe perfusion pile, cast-in-situ bored pile and digging hole filling pile.
The content of the invention
It is an object of the invention to provide a kind of prefabricated bamboo joint pile and its construction method, can effectively improve pore-forming speed
Degree, the frictional force of increase stake and soil and economizes on resources and the purpose of cost of labor.
The present invention to achieve these goals, adopts the following technical scheme that：
A kind of prefabricated bamboo joint pile, enlarging stake are divided into termination by splice sections and cut native enlarging pile cutoff and middle part splicing pile cutoff；
Cut native enlarging pile cutoff and be made up of circular pile body part and circular flared part in termination；
Circular pile body part and circular flared part surface are all uniformly provided with circular opening, and the concrete rib of circular ring type, in advance
The stitching portion of pile element processed is provided with splicing bayonet socket and splicing enlarging, and the bottom of circular flared part is provided with the steel sheath of circle；
Middle part splicing pile cutoff two ends are equipped with splicing bayonet socket and splicing enlarging, and in-between section is circular pile body part, circular stake
Body part surface is uniformly provided with circular opening, and the concrete rib of circular ring type.
A kind of construction method of prefabricated bamboo joint pile is as follows the step of this method：
A, first spoil, dig to the depth of one section of prefabricated pile cutoff；
B, the termination of prefabricated enlarging stake is cut into native pile cutoff lifting to be put into the soil body excavated, when guarantee is installed in place, pile body is protected
Hold vertical；
C, the following soil body is drilled loose by rotary digging drilling hole technology, taken out, at the same time, termination cut native pile cutoff can because deadweight and
Sink；
When D, specifying absolute altitude when sinking to the stage, the splice sections lifting of prefabricated enlarging stake is buried, carried out with termination enlarging stake
Splicing；
E, and then C, D steps are repeated, until stake bottom reaches designed elevation；
F, the casting concrete in stake, pile body structure is formed.
The equally distributed circular opening, it is in casting process, make the concrete in pile body be overflow from hole
Go out, increase with the contact surface of the soil body to reach the effect of increase frictional force.
The pile body flared part, it is in order to increase the floor space of pile body, to improve bearing capacity of pile tip.
The steel sheath, first, in order to protect end concrete wall not by soil fail, second, making pile crown part form phase
To the sharp smooth sinking cut native face, facilitate pile body.
Flared part in the middle part enlarging splice sections, it is to increase the frictional force of pile lining and soil.
Beneficial effects of the present invention：
1st, the present invention may be such that the frictional force of stake and bottom bearing get a promotion；
2nd, the present invention greatly improves the efficiency for excavating pore-forming；
3rd, the present invention can reduce manual work, reduce Contraction in Site；
4th, the invention enables job site noise is small, pollution is small；
5th, the present invention realizes factorial praluction, convenient and swift.
