Description
Technical field
The utility model relates to pipe technology fields, concretely relate to coiling steel pipe.
Background technique
Coiling steel pipe includes steel pipe body, and the steel pipe body is coiled to form with steel plate, and material used is strip
The steel plate of shape, steel plate coiling more weeks form helical form, the steel plate contact site between adjacent week is welded and coils steel pipe；It is existing
Have in technology, coiling steel duct is not provided with strengthening part, since coiling steel pipe is buried in underground throughout the year, generally requires above
Place weight, such coiling steel pipe has the shortcomings that be easily deformed, bear can be poor.
Summary of the invention
The purpose of the present invention is to disadvantages mentioned above, provide it is a kind of be unlikely to deform, the coiling steel that ability to bear is strong
Pipe --- the coiling steel pipe of built-in steel loop.
The object of the present invention is achieved like this: the coiling steel pipe of built-in steel loop, including steel pipe body, the steel pipe sheet
Body is to be welded to coil steel pipe with the steel plate contact site between steel plate coiled coil, adjacent week, the steel pipe body
Inside has inner cavity；It is characterized in that: having spaced steel loop, steel loop periphery and steel pipe inside the steel pipe body inner cavity
Chamber body is contacted and is headed on around inner cavity, and the steel loop side and steel pipe body are welded and fixed.
Further speaking, the steel loop side and inside have the structure of chamfering.
Further speaking, the steel loop side is the structure of scarf.
Further speaking, the material of the steel loop is high-strength glass hard steel.
Further speaking, there are also one layer of rubber pads between the steel loop and steel pipe body inner cavity.
The beneficial effects of the present invention are: such coiling steel pipe has the advantages that be unlikely to deform, ability to bear is strong；
The steel loop side and inside have the structure of chamfering, also have and reduce the excellent of steel duct flowing water resistance
Point；
The steel loop side is the structure of scarf, also has and preferably reduces the excellent of steel duct flowing water resistance
Point；
The material of the steel loop is high-strength glass hard steel, also has the advantages that intensity is higher；
There are also one layer of rubber pad between the steel loop and steel pipe body inner cavity, also have the advantages that connection is stronger.
Detailed description of the invention
Fig. 1 is the side schematic view with the utility model.
Fig. 2 is A-part A diagrammatic cross-section in Fig. 1.
Fig. 3 is B-part B diagrammatic cross-section in Fig. 2.
Fig. 4 is enlarged drawing at C in Fig. 2.
Wherein: 1, steel pipe body 2, inner cavity 3, steel loop 4, the structure 5 of chamfering, rubber pad.
Specific embodiment
The invention will be further described with reference to the accompanying drawing.
As shown, the coiling steel pipe of built-in steel loop, including steel pipe body 1, the steel pipe body are with steel plate spiral
Steel plate contact site between coiling, adjacent week, which is welded, coils steel pipe, has inner cavity 2 inside the steel pipe body；
It is characterized in that: having spaced steel loop 3, steel loop periphery and steel pipe body lumen contact inside the steel pipe body inner cavity
And head on around inner cavity, the steel loop side and steel pipe body are welded and fixed.
Further speaking, the steel loop side and inside have the structure 4 of chamfering.
Further speaking, the steel loop side is the structure of scarf.
Further speaking, the material of the steel loop is high-strength glass hard steel.
Further speaking, there are also one layer of rubber pads 5 between the steel loop and steel pipe body inner cavity.
Above is only a specific embodiment of the present invention, but structure feature of the invention is not limited to this, any ability
Within the field of the present invention, made changes or modifications all cover in the scope of the patents of the invention the technical staff in domain.
