Abstract
The utility model discloses a stake end enlarged footing precast pile, cylindricality pile body and tapered pile point including fixed connection, be equipped with the slip casting pipe in the pile body, be equipped with highlights on the tapered pile point, highlights is equipped with the opening, the slip casting pipe is connected with the opening. The utility model discloses a change precast pile stake point appearance to set up highlights at the stake point, carry out the slip casting of stake end after the pressure stake is accomplished, a messenger highlights and a stake week soil formation community, thus strengthen the withdrawal resistance of precast pile by a wide margin.
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 stake end 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, increases the method that stake is long, the therefore greatly large increase of construction cost.The uplift resistance that the construction technologies such as expansion at the bottom of how applying improve stake is still technological gap.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of stake end enlarged footing preformed pile, by changing preformed pile pile top profile, and ledge being set in pile top, after piling completes, carrying out pile end grouting, 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 stake end enlarged footing preformed pile, comprise the cylindricality pile body and taper pile top that are fixedly connected with, Grouting Pipe is provided with in described pile body, described taper pile top is provided with ledge, described ledge is provided with opening, and described Grouting Pipe is connected with opening.
In technique scheme, described cylindricality pile body is pile tube, and described pile top is conical, and the basal diameter of described conical pile top is greater than pile tube diameter, and described ledge is the part that conical pile top bottom surface exceeds pile body.
In technique scheme, described cylindricality pile body is square pile, and described pile top is pyramid, and described ledge is positioned at the side of pyramid pile tip.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model changes preformed pile pile top profile, in pile top, ledge is set, after piling completes, pile end grouting is carried out by the Grouting Pipe being located at pile body inside, ledge and soil around pile is made to form community, significantly enhance the uplift resistance of preformed pile, and construction technology is simple, obviously can reduce cost under the condition reaching same uplift resistance design load.

Fig. 1 is the utility model structural representation in embodiment one.
Fig. 2 is the utility model structural representation in embodiment two.
Wherein: 1, pile body; 2, pile top; 3, Grouting Pipe; 4, ledge.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment one: shown in Figure 1, a kind of stake end enlarged footing preformed pile, comprise the tubular pile body 1 and conical pile top 2 that are welded and fixed, Grouting Pipe 3 is provided with in described tubular pile body, the basal diameter of described conical pile top is greater than tubular pile body diameter, described conical pile top bottom surface exceeds the part of pile body as ledge 4, and described ledge is provided with opening, and described Grouting Pipe is connected with opening.
Embodiment two: shown in Figure 2, a kind of stake end enlarged footing preformed pile, comprise the square pile pile body 1 and pyramid pile tip 2 that are welded and fixed, Grouting Pipe 3 is provided with in described square pile pile body, the side of described pyramid pile tip is provided with ledge 4, described ledge is provided with opening, and described Grouting Pipe is connected with opening.
