Abstract
The utility model relates to a building foundation pile with high bearing capacity, which has the structure that the upper part is arranged into a steel pipe; a lower steel dowel arranged at the inner part of the steel pipe directly extends into a lower tubular prefabricated pile body; a lower steel dowel of the lower prefabricated pile body, which is arranged in the lower prefabricated pile body, penetrates a cast-in-place base to be knocked into hardpan, and the upper part steel pipe and a lower part prefabricated pile body are anchored to be as a whole through an upper cast-in-place base, the upper end of the upper part steel pipe is still provided with a multi-stage prefabricated pile body, radial rebars are arranged in the upper cast-in-place concrete base and a cast-in-place base, and the diameter of the upper part steel pipe is greater than the diameter of the lower tubular prefabricated pile body. The high bearing capacity building foundation friction pile can significantly improve the bearing capacity and impact resistance and utilization ratio of a single pipe body, and has wide application.
Description
Technical field
The utility model relates to a kind of building foundation pile foundation, particularly relates to a kind of high-bearing capacity foundation pile of building of using in the highrise building foundation engineering of being adapted at.
Technical background
At present in the pile foundation engineering of ground, adopt three kinds of tube-sinking cast-in-situ pile, preformed pile and large diameter bored piles usually.Wherein the large diameter bored pile bearing capacity is the highest, but its involve great expense, work efficiency is low, and is and seriously polluted during construction, so only be used for highrise building and the high building of requirement for bearing capacity.The quality of preformed pile is good, bearing capacity is also higher, but its cost is also high, generally is used for the higher building of safe class.All belong to friction pile by the described three kinds of stakes of classifying of holding capacity situation.What wherein be most widely used is tube-sinking cast-in-situ pile, accounts for 50% of all kinds of stake total quantitys, and this pile body is a cast-in-situ steel concrete, and pile crown is prefabricated; But broken pile, necking often appear in this kind stake in work progress, thereby cause having approximately can't meet the quality requirement of tube-sinking cast-in-situ pile of 10-20%, force the designer to reduce the standard of bearing capacity of single pile, cause down stake to be gathered, cause soil body gross distortion, even jeopardize the quality of pile body; This another shortcoming is that bearing capacity is low, if for improving the bearing capacity of single pile, base diameter is excessive not only can to increase constructional difficulties, and can have a negative impact to the performance of its end load, cause the bearing capacity of demarcation to be had a greatly reduced quality, that is to say and attempt again the mode of enlarged base diameter to improve the potentiality of bearing capacity of single pile very limited, be difficult to break through.Therefore make its application be subjected to certain limitation.Simultaneously, pile body of the prior art in use exists bearing capacity and the more weak problem of anti-impact force.
The utility model content
The problem that the utility model exists at prior art, provide a kind of, solved pile body in use bearing capacity and the more weak problem of anti-impact force for highly versatile applied widely, energy adapt to different regions soil layer geology situation of change, improve strength of materials utilization rate, make the higher high-bearing capacity foundation pile of building of bearing capacity of single pile more satisfactoryly.
The technical scheme that the utility model technical solution problem is adopted is: epimere is set to steel pipe, the following joint bar of the epimere steel pipe that is provided with in the steel pipe stretches in the hypomere tubulose precast pile, the following joint bar of the hypomere precast pile that is provided with in the hypomere tubulose precast pile passes cast-in-situ base and hammers into hardpan, by last Cast-in-place concrete base epimere steel pipe and hypomere precast pile are fused, the upper end of epimere steel pipe also is provided with multistage precast pile, be provided with the radiation muscle in last Cast-in-place concrete base and the cast-in-situ base, the diameter of epimere steel pipe is greater than the diameter of hypomere tubulose precast pile.
The firmware concrete is set in the described steel pipe.
Advantage of the present utility model and effect are as follows:
The utility model compared with prior art, because the performance that is provided with the lower bottom base bearing capacity of upper bed-plate produces good influence, obviously improve the bearing capacity of single pile and the utilization rate of the strength of materials, reach the Expected Results of design easily, satisfy the needs of construction work better, no matter simultaneously applied widely is that high level or low-rise building, safe class and ground soil property situation can both be combined into the immersed tube prefabricated multistage under-reamed pile that is complementary with it.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of foundation pile of building of the present utility model.
Among the figure: 1, Cast-in-place concrete base; 2, go up the Cast-in-place concrete base; 3, hypomere tubulose precast pile; 4, epimere steel pipe; 5, the following joint bar of hypomere precast pile; 6, the following joint bar of epimere steel pipe; 7, radiation muscle, 8, concrete.
The specific embodiment
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, but protection domain of the present utility model is not limit by embodiment.
Embodiment
As shown in Figure 1, its structure is as follows: epimere is set to steel pipe 4, the firmware concrete eight is set in the steel pipe 4, the following joint bar 6 of the epimere steel pipe in the steel pipe directly stretches in the hypomere tubulose precast pile 3, the following joint bar 5 of the hypomere precast pile that is provided with in the hypomere tubulose precast pile 3 passes cast-in-situ base 1 and hammers into hardpan, by last Cast-in-place concrete base 2 epimere steel pipe 4 and hypomere precast pile 3 are fused, can also be provided with one-level in the upper end of epimere steel pipe 4 as required, two-stage or eight grades of precast piles, be provided with radiation muscle 7 in last Cast-in-place concrete base 2 and the cast-in-situ base 1, the diameter of epimere steel pipe 4 is greater than the diameter of hypomere tubulose precast pile 3.
Claims (2)
1, a kind of high-bearing capacity foundation pile of building, it is characterized in that structure is as follows: epimere is set to steel pipe, the following joint bar (6) of the epimere steel pipe that is provided with in the steel pipe stretches in the hypomere tubulose precast pile (3), the following joint bar (5) of the hypomere precast pile that is provided with in the hypomere tubulose precast pile (3) passes cast-in-situ base (1) and hammers into hardpan, by last Cast-in-place concrete base (2) epimere steel pipe (4) and hypomere precast pile (3) are fused, the upper end of epimere steel pipe (4) also is provided with multistage precast pile, be provided with radiation muscle (7) in last Cast-in-place concrete base (2) and the cast-in-situ base (1), the diameter of epimere steel pipe (4) is greater than hypomere tubulose precast pile (3) diameter.
