Embodiment Construction
[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as they are within the rights of the present invention All claims are protected by patent law.
[0035] Such as figure 1 As shown, an underground connecting pipeline includes multi-section spliced pipe body 1, and adjacent pipe bodies 1 are spliced together by connecting assembly 2. The effect of cushioning in the radial direction of the pipe body 1.
[0036] Such as figure 2 with image 3 As shown, the connection assembly 2 includes a fixing ring 3 located at the splicing part of the outside of the pipe body 1 and other pipe bodies 1, and a plurality of limit posts ...

The invention discloses an underground connecting pipeline which has the advantage that the supporting strength of the pipeline is better. The underground connecting pipeline comprises a plurality of spliced pipe bodies, wherein connecting components for connecting the pipe bodies are arranged between adjacent pipe bodies; buffer parts which play the role of buffering when the pipe bodies are under a radial acting force are arranged in the connecting components; and a stainless steel protective cover with a semi-circular cross section is arranged at upper sides of the pipe bodies. When the pipe bodies are connected through the connecting components, the buffering parts play the role of radial buffering to ensure that the pipe bodies are avoided being damaged under stress under the circumstance of complete rigid connection; part of acting force is shared for the pipe bodies through the buffer deformation of the buffering parts in the radial direction to ensure that the pipeline has better strength; and in the meantime, the stainless steel protective cover with the semi-circular cross section is arranged at upper sides of the pipe bodies to ensure that the pressure can be shared by the whole pipe bodies when the pipe bodies are under stress and the pipe bodies are not easy to break.
Description
technical field [0001] The invention relates to a pipeline, in particular to an underground connecting pipeline. Background technique [0002] The invention patent with the publication number CN1785638A discloses a preparation method of a small-diameter thin-walled cement sewage pipe. The cement sewage pipe with small pipe diameter and thin pipe wall can be prepared by the method. [0003] However, the cement sewage pipe produced by this invention patent has the following problems: the supporting strength of the cement sewage pipe with small diameter and thin wall is relatively poor, and the cement sewage pipe buried underground may break when the road surface is under a relatively large pressure Case. Contents of the invention [0004] The object of the present invention is to provide an underground connecting pipeline, which has the advantage of better supporting strength of the pipeline. [0005] The above-mentioned technical purpose of the present invention is achie...
