Abstract
The utility model discloses a pipeline provided with a built-in metal bellows and used for engineering. The pipeline comprises a pipeline body which is made of concrete or cement or cement mortar or resin cement mixture, and the metal bellows having the same coaxial line with the pipeline body is installed inside the pipeline body. The bellows is composed of a wave crest section, a first height section, a wave trough section and a second height section, wherein the wave crest section, the first height section, the wave trough and the second height section are successively connected in a circulated mode along the axial direction. A wave trough section through hole is formed in the wave trough section, a wave crest section through hole is formed in the wave crest section, and wave crest section through holes are formed in the first height section and the second height section. By means of the technical scheme, the metal bellows having the same axial line with the pipeline body is installed inside the pipeline body which is made of the concrete or the cement or the cement mortar or the resin cement mixture, so that intensity and ring stiffiness of the pipeline body are enhanced fully.
Description
Technical field
The utility model relates to a kind of pipeline, relates in particular to the pipeline that a kind of engineering is used the built-in metal bellows.
Background technique
Engineering adopts concrete or cement or slush or resin cement mixture to make with pipeline mostly, and the pipeline strength of this structure is inadequate, is easy to fragmentation.The reinforcing bar that reinforing function has been set is also arranged, but intensity does not still meet in special engineering the requirement to pipe ring rigidity in pipeline body.
The model utility content
The utility model provides the pipeline of the strong engineering of a kind of ring stiffness with the built-in metal bellows in order to solve deficiency of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of engineering pipeline of built-in metal bellows, comprise the pipeline body of being made by concrete or cement or slush or resin cement mixture, be provided with the metal bellows with the pipeline body coaxial line in the described pipeline body.
Described bellows by vertically in turn and circulation the crest section, the first height section, trough section and the second height section that connect consist of, described trough section offers trough section through hole.
Described crest section offers crest section through hole.
Described the first height section and the second height Duan Jun offer height section through hole.
The total surface area of the crest section through hole on the described crest section is less than the total surface area of the trough section through hole on the trough section.
The total surface area of the height section through hole on described one first height section or the second height section is less than the total surface area of the crest section through hole on the crest section.
Be arranged with at least one pair of in the pipeline body along the steel band of pipeline body axial direction.
Adopt technique scheme, the metal bellows of setting and pipeline body coaxial line in the pipeline body that concrete or cement or slush or resin cement mixture are made, the intensity of so abundant enhancing pipeline body and ring stiffness.Offer some trough section through holes in the trough section, offer crest section through hole in the crest section, offer height section through hole in the first height section or the second height section; Can fully reduce metallic material like this, alleviate the weight of whole bellows and reduce the cost of production of bellows.The total surface area of the crest section through hole on crest section is less than the total surface area of the height section through hole on the total surface area of the trough section through hole on the trough section, first height section or the second height section total surface area less than the trough section through hole on the trough section; Be according to the in use stressed further restriction that varies in size and carry out of different sections like this, thereby the intensity of guaranteeing whole bellows is not subjected to large impact.Better reinforing function is played in the setting of steel band.
Description of drawings
