Abstract
The invention belongs to the realm of building construction, prestressed concrete pipe pile blocking device is prevented more particularly to one kind, including circular steel plate, screw-thread steel and tubular pole, the screw-thread steel 90 degree of bending at one third, the screw-thread steel shorter end and circular steel plate vertical welding, the screw-thread steel are three, and uniform welding is in circular steel plate, the circular steel plate is placed on inside tubular pole, and the screw-thread steel longer end is overlapped on the pipe pile end portion surface.One kind provided by the invention prevents prestressed concrete pipe pile blocking device, Soil Surrounding slides to tubular pole when effectively preventing earth excavation, to avoid spending the soil in a large amount of manpower and material resources cleaning tubular poles, also tubular pole protective action can be played, scene self-control, it is reusable, improve construction speed.
Description
Technical field
The invention belongs to the realm of building construction, and in particular to one kind prevents prestressed concrete pipe pile blocking device.
Background technique
In building construction process, after pile foundation engineering is constructed, tamped through often there is stake core by soil after earth excavation
The phenomenon that, the later period needs a large amount of manpower and material resources to remove stake core soil, increases construction cost and influences construction speed.Therefore in order to keep away
Exempt from the blocking of prestressed concrete pipe pile stake core, being badly in need of one kind prevents prestressed concrete pipe pile blocking device, effectively prevent the earthwork
Soil Surrounding slides to stake core when excavation, to avoid spending a large amount of manpower and material resources cleaning stake core soil, can also play a core protection
Effect, improves construction speed.
Summary of the invention
For the technical problems in the prior art, the purpose of the present invention is to provide one kind to prevent prestressed concrete
Tubular pole blocking device, to achieve the goals above, the technical scheme adopted by the invention is as follows:
One kind preventing prestressed concrete pipe pile blocking device, including circular steel plate, screw-thread steel and tubular pole, the screw-thread steel
90 degree of bending at one third, the screw-thread steel shorter end and circular steel plate vertical welding, the screw-thread steel are three, uniformly
It is welded in circular steel plate, the circular steel plate is placed on inside tubular pole, and the screw-thread steel longer end is overlapped on the tubular pole
End surface.
Preferably, for the circular steel plate with a thickness of 3mm, diameter is 4~6mm smaller than tubular pole internal diameter.
Preferably, the screw-thread steel length is 15cm, diameter 12mm.
Preferably, the screw-thread steel guarantees the spiral shell with depending on circular steel plate spot welding position oblong steel plate diameter
Line steel longer end is overlapped on the lap of splice on the pipe pile end portion surface not less than 4cm.
Preferably, the tubular pole from the ground 1m when, be put into the circular steel plate.
One kind provided by the invention prevents prestressed concrete pipe pile blocking device, week when effectively preventing earth excavation
Side soil slides to pipe pile core, to avoid spending a large amount of manpower and material resources cleaning stake core soil, can also play a core protective action,
Improve construction speed.
Detailed description of the invention
Fig. 1 is that one kind prevents prestressed concrete pipe pile blocking device schematic front view；
Fig. 2 is that one kind prevents prestressed concrete pipe pile blocking device schematic top plan view；
1. circular steel plate, 2. screw-thread steel, 3. tubular pole in figure
Specific embodiment
One kind to further describe the present invention prevents prestressed concrete pipe pile blocking device, with reference to the accompanying drawing to it
It is described further.
In Fig. 1-2: one kind preventing prestressed concrete pipe pile blocking device, including circular steel plate 1, screw-thread steel 2 and tubular pole
3, the screw-thread steel 2 90 degree of bending at one third, 2 shorter end of screw-thread steel and 1 vertical welding of circular steel plate, the spiral shell
Line steel 2 is three, and uniform welding is in circular steel plate 1, and the circular steel plate 1 is placed on inside tubular pole 3, and the screw-thread steel 2
Longer end is overlapped on 3 end surface of tubular pole.
For the circular steel plate 1 with a thickness of 3mm, diameter is 4~6mm smaller than 3 internal diameter of tubular pole.
2 length of screw-thread steel is 15cm, diameter 12mm.
The screw-thread steel 2 guarantees the screw-thread steel 2 with depending on 1 spot welding position oblong steel plate of circular steel plate, 1 diameter
Longer end is overlapped on the lap of splice of 3 end surface of tubular pole not less than 4cm.
The tubular pole 3 from the ground 1m when, be put into the circular steel plate 2.
In pile foundation construction, last root canal pile is depressed at 1m from the ground, will prevent prestressed concrete pipe pile blocking dress
It puts in tubular pole, then tubular pole is depressed at absolute altitude；In this way in earth excavation, Soil Surrounding is just effectively prevent to slide to tubular pole
It is interior, it after earth excavation, then will prevent prestressed concrete pipe pile blocking device from taking out, the later period is avoided to use a large amount of manpowers
Material resources clear up the soil in tubular pole, and the device is reusable, and scene self-control, tubular pole protects before also can be used as earth excavation.
The above content is just an example and description of the concept of the present invention, not detailed place, is the art
Well-known technique, affiliated those skilled in the art make various modifications or additions to the described embodiments or
It is substituted in a similar manner, it as long as it does not deviate from the concept of invention or beyond the scope defined by this claim, should all
It belongs to the scope of protection of the present invention.
