Abstract
The utility model discloses a kind of pile body enlarged footing preformed pile, comprise the cylindricality pile body and taper pile top that are fixedly connected with, described cylindricality pile body inner with pile body central axis for axis of symmetry is arranged with at least two Grouting Pipe, described pile body sidewall is provided with the grouting port be connected with Grouting Pipe, corresponds to grouting port lower end and be provided with jut outside described pile body.The utility model is by changing preformed pile pile body profile, at pile body, ledge is set, pile body slip casting is carried out after piling completes, ledge and soil around pile is made to form community, thus significantly strengthen the uplift resistance of preformed pile, and technique is simple, obviously can reduce cost under the condition reaching same uplift resistance design load.
Description
Technical field
The utility model relates to a kind of building unit, particularly relates to a kind of building prefabrication stake, is specifically related to a kind of pile body enlarged footing preformed pile.
Background technology
At present, construction market has various castinplace pile, preformed pile, anchor pole, anchor cable etc. for the pile-type of resistance to plucking.The anti-pulling capacity of various pile-type all by pile body side and the soil body frictional resistance provide, institute thinks improves stake anti-pulling capacity, engineers and technicians are according to engineering practice, have developed the pile-type such as enlarged footing anchor cable, bottom-enlarging filling pile, the effect of major part bottom stake can be played like this, increase resistance to plucking resistance, thus obtain larger stake uplift resistance.Preformed pile application is in the market more, and in order to improve the uplift resistance of preformed pile, general employing expands stake footpath, increase the method that stake is long, not only increase the greatly large increase of construction cost, and the connecting portion between stake is often the weak part of uplift pile, have impact on the performance of uplift resistance.How on cost-saving basis, by changing outward appearance and the construction technology of stake, the uplift resistance improving stake is still technological gap.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of pile body enlarged footing preformed pile, by changing preformed pile pile body profile, ledge being set at pile body, after piling completes, carrying out pile body slip casting, make ledge and soil around pile form community, thus significantly strengthen the uplift resistance of preformed pile.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of pile body enlarged footing preformed pile, comprise the cylindricality pile body and taper pile top that are fixedly connected with, described cylindricality pile body inner with pile body central axis for axis of symmetry is arranged with at least two Grouting Pipe, described pile body sidewall is provided with the grouting port be connected with Grouting Pipe, corresponds to grouting port lower end and be provided with jut outside described pile body.
In technique scheme, described cylindricality pile body can be pile tube or square pile.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is by changing preformed pile pile body profile, at pile body, ledge is set, pile body slip casting is carried out after piling completes, ledge and soil around pile is made to form community, thus significantly strengthen the uplift resistance of preformed pile, and technique is simple, obviously can reduce cost under the condition reaching same uplift resistance design load.
