Abstract

The utility model relates to pipe technology fields, title is the coiling steel pipe of external steel loop, including steel pipe body, the steel pipe body is to be welded to coil steel pipe with the steel plate contact site between steel plate coiled coil, adjacent week, has inner cavity inside the steel pipe body；It is characterized in that: having spaced steel loop outside the steel pipe body, steel loop inner circumferential and steel pipe body periphery contact and are welded to connect, there are also link up with outside the steel loop, the material of the steel loop is high-strength glass hard steel, there are also lateral dowels between adjacent steel loop, dowel both ends are welded on steel loop, and centre is welded on outside steel pipe body.Such coiling steel pipe has the advantages that be unlikely to deform, ability to bear is strong.

Description

The coiling steel pipe of external steel loop

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 pipe external is not provided with strengthening part, since coiling steel pipe is buried in underground throughout the year, often needs 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 external steel loop.

The object of the present invention is achieved like this: the coiling steel pipe of external 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 inner circumferential and steel pipe body outside the steel pipe body Periphery contacts and is welded to connect.

Further speaking, there are also link up with outside the steel loop.

Further speaking, the material of the steel loop is high-strength glass hard steel.

Further speaking, there are also lateral dowel between adjacent steel loop, dowel both ends are welded on steel loop, intermediate It is welded on outside steel pipe body.

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；

There are also linking up with outside the steel loop, also have the advantages that lifting is convenient；

The material of the steel loop is high-strength glass hard steel, and there are also lateral dowel, dowels between adjacent steel loop Both ends are welded on steel loop, and centre is welded on outside steel pipe body, also have the advantages that intensity is higher.

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. 1.

Wherein: 1, steel pipe body 2, steel loop 3, hook 4, dowel.

Specific embodiment

The invention will be further described with reference to the accompanying drawing.

As shown in Figure 1, 2, 3, the coiling steel pipe of external steel loop, including steel pipe body 1, the steel pipe body are to use steel plate Steel plate contact site between coiled coil, adjacent week, which is welded, coils steel pipe, has inside the steel pipe body interior Chamber；It is characterized in that: there is spaced steel loop 2 outside the steel pipe body, steel loop inner circumferential and the contact of steel pipe body periphery And it is welded to connect.

Further speaking, there are also hooks 3 outside the steel loop.

Further speaking, there are also lateral dowel 4 between adjacent steel loop, dowel both ends are welded on steel loop, in Between be welded on outside steel pipe body.

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.

Claims
