Abstract
The utility model discloses a kind of steel pipe pile foundation, the pile crown of steel pipe front end is fixed on including steel pipe and suit, the pile crown forms by the pile top of taper and with the sleeve pipe that pile top rear end is fixedly connected, the internal diameter of described sleeve pipe and the external diameter of steel pipe match, described sleeve pipe rear end axially offers otch and forms expansion type elastic card claw, the described one end of expansion type elastic card claw away from pile top is provided with the hook portion of cannula center extension, and the steel pipe is inserted into described sleeve pipe and gripped by expansion type elastic card claw.In the utility model pile top by expansion type elastic card claw realize with the connection of steel pipe, the assembling process is convenient and swift, reduces the installation that in-site installation carries out pile crown, improves operating efficiency, at the same also eliminate because welding and caused by etching problem.
Description
Technical field
The utility model belongs to building field, and in particular to a kind of steel pipe pile foundation.
Background technology
Steel pipe pile foundation is widely used in hydraulic engineering, science of bridge building, industry and the basis of civil buildings etc..Existing steel pipe
The work progress of pile foundation is：The steel-pipe pile designed and produced is transported to job site, in order to make steel-pipe pile smoothly be driven into
Or in press-in soil layer, the pile crown of taper is typically welded at the stake end of steel-pipe pile, is then sling stake with loop wheel machine, align piles position, use
Stake is squeezed into or during static pressure buries by stake machine, when pile crown enters in supporting course at designed elevation, that is, stops piling or static pressure.Pile crown needs
It is welded in pile pipe, installation is inconvenient, adds labor intensity, and high to the quality requirement of welding, influences efficiency of construction,
For operation steel pipe pile foundation in river course or in ocean, steel pipe pile foundation construction working condition is more severe, and weld is easy
Corrosion so that steel pipe pile foundation bearing capacity declines.
Utility model content
The purpose of this utility model is to provide the steel pipe pile foundation that a kind of efficiency of construction is high, bearing strength is high.
In order to solve the above technical problems, steel pipe pile foundation provided by the utility model, including steel pipe and suit are fixed on
The pile crown of steel pipe front end, the pile crown form by the pile top of taper and with the sleeve pipe that pile top rear end is fixedly connected, described sleeve pipe
The external diameter of internal diameter and steel pipe matches, and described sleeve pipe rear end axially offers otch and forms expansion type elastic card claw, the expansion
The one end of formula elastic card claw away from pile top is provided with the hook portion of cannula center extension, and the steel pipe is inserted into described sleeve pipe simultaneously
Gripped by expansion type elastic card claw.
Further, inner tube is arranged with the steel pipe, is poured between the steel pipe and inner tube formed with reinforced concrete.
Further, described outer wall of steel pipe is provided with zinc coat.
Compared with prior art, the utility model has the advantages that：Pile top passes through expansion type in the utility model
Elastic card claw realizes the connection with steel pipe, and the assembling process is convenient and swift, reduces the installation that in-site installation carries out pile crown, carries
High operating efficiency, at the same also eliminate because welding and caused by etching problem.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in Figure 1-Figure 3, steel pipe pile foundation provided by the utility model, including steel pipe 1 and suit are fixed on steel pipe 1
The pile crown 2 of front end, the pile crown 2 form by the pile top 3 of taper and with the sleeve pipe 4 that the rear end of pile top 3 is fixedly connected, described sleeve pipe 4
The external diameter of internal diameter and steel pipe 1 match, the rear end of described sleeve pipe 4 axially offers otch and forms expansion type elastic card claw 5, described
Steel pipe 1 is inserted into described sleeve pipe 4 and gripped by expansion type elastic card claw 5, is determined by the clamping of expansion type elastic card claw 5
Position steel pipe, it is convenient not assemble tightly, improves operating efficiency, at the same steel pipe 1 be sleeved in sleeve pipe after directly supported with the rear end face of pile top 3
Connect, soil layer prevents steel pipe 1 from being destroyed and influenceing whole base the reaction force of steel pipe 1 during can effectively buffering piling
The bearing capacity of plinth, the hook portion 6 of the center of sleeve pipe 1 extension is provided with the one end of expansion type elastic card claw 5 away from pile top 3, if
The insertion that the one side of hook portion 6 facilitates steel pipe is put, the holding capability of expansion type elastic card claw 5 can also be improved in addition.
As depicted in figs. 1 and 2, another specific embodiment of the present utility model, coaxial sleeve is provided with inner tube 7 in steel pipe 1,
Poured between the steel pipe 1 and inner tube 7 formed with reinforced concrete 8, integrally-built section is effectively increased by increasing reinforced concrete 8
Modulus, improve structural-load-carrying capacity；Can reduce simultaneously foundation pile displacement deformation amount during use, outer layer pipe wall thickness with again
Amount.
To improve the corrosion resistance of steel pipe 1, zinc coat is provided with the outer wall of steel pipe 1.
Work progress of the present utility model is as follows：
1st, preparation steel pipe 1, inner tube 7 and pile crown 2 and concrete；
2nd, will be abutted in the plug-in-sleeve 4 of steel pipe 1 and with the rear end face of pile top 3, expansion type elastic card claw 5 is clamped steel pipe
1；
3rd, steel pipe 1 is squeezed into ground using special pile driving equipment, pile top 3 is reached in supporting course at designed elevation,
Stop piling；
4th, inner tube 7 is lifted in steel pipe 1 using lifting appliance, while steel reinforcement cage 9 is put between steel pipe 1 and inner tube 7
Annular chamber in and placing concrete, whole steel pipe pile foundation is formed after concrete setting.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
