Abstract
The utility model relates to a belled cast-in-place pile comprising a plurality of tubular precast pile bodies which are coaxially arranged and a pile head. The tubular precast pile bodies are anchored with each other through cast-in-site concrete bases, the front end of the pile head is of a conical shape, and the pile head is anchored at the lower end of the bottommost tubular precast pile body. The belled cast-in-place pile realized via the technical scheme has more stable effect. .
Description
Technical field
The utility model relates to a kind of perfusion expanded bore pile.
Background technology
In the past in the pile foundation engineering of ground, often adopt three kinds of pipe perfusion pile, preformed pile and large diameter drill hole piles.Wherein pipe perfusion pile should have the most extensively, and broken pile, necking appear in this kind stake easily in work progress, and cause quality not reach standard, and also there is the low shortcoming of bearing capacity in it.The quality of preformed pile is good, bearing capacity is also higher relatively, but its cost height generally is applied to the higher building of safe class.Wherein the large diameter borehole pile capacity is the highest, but its involve great expense, work efficiency is low, and is and seriously polluted during construction, so only be applied to highrise building and the high building of requirement for bearing capacity.So occurred highly versatile applied widely, the comparatively ideal adaptation of energy different regions soil layer geology situation of change afterwards, improved strength of materials utilization rate, made the higher building foundation perfusion expanded bore pile of bearing capacity of single pile, but there is the shortcoming on the ground that is difficult for insertion in it, and its horizontal direction does not have the shortcoming of wedging function, thereby built on the sand.
Summary of the invention
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of more firm perfusion expanded bore pile.
For achieving the above object, the utility model provides following technical scheme: a kind of perfusion expanded bore pile, the tubulose precast pile that is coaxial setting that comprises some quantity, pass through the anchoring of Cast-in-place concrete base phase between each tubulose precast pile, also include pile crown, the tapered setting of the front end of described pile crown, and pile crown is anchored at the lower end of the tubulose precast pile of bottommost.
By adopting technique scheme, because the insertion ground that expanded bore pile can be more firm is poured in the effect of pile crown.
The utility model further arranges: the periphery of described pile crown is provided with the acclivitous pawl of some quantity.
By adopting technique scheme, because the effect of pawl, the perfusion expanded bore pile can form vertically and agree with, and has further improved the steadiness of perfusion expanded bore pile.
The utility model further arranges: the prefabricated pipe shaft of described each tubulose is provided with the joint bar that extends to the prefabricated pipe shaft of tubulose that is adjacent respectively.
By adopting technique scheme, improved the steadiness of perfusion expanded bore pile.
The utility model further arranges: be provided with the radiation muscle in the described Cast-in-place concrete base.
By adopting technique scheme, further improved the steadiness of perfusion expanded bore pile.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model example structure figure.
The specific embodiment
Referring to accompanying drawing 1, the disclosed perfusion expanded bore pile of the utility model, the tubulose precast pile 1 that is coaxial setting that comprises some quantity, pass through the 2 phase anchorings of Cast-in-place concrete base between each tubulose precast pile 1, also include pile crown 3, the tapered setting of the front end of described pile crown 3, and pile crown 3 is anchored at the lower end of the tubulose precast pile 1 of bottommost.By adopting technique scheme, because the insertion ground that expanded bore pile can be more firm is poured in the effect of pile crown 3.
Present embodiment further arranges: the periphery of described pile crown 3 is provided with the acclivitous pawl 301 of some quantity.By adopting technique scheme, because the effect of pawl 301, the perfusion expanded bore pile can form vertically and agree with, and has further improved the steadiness of perfusion expanded bore pile.
Present embodiment further arranges: the prefabricated pipe shaft 1 of described each tubulose is provided with the joint bar 101 that extends to the prefabricated pipe shaft 1 of the tubulose that is adjacent respectively.By adopting technique scheme, improved the steadiness of perfusion expanded bore pile.
Present embodiment further arranges: be provided with radiation muscle 201 in the described Cast-in-place concrete base 2.By adopting technique scheme, further improved the steadiness of perfusion expanded bore pile.
