Detailed Description
Example one
As shown in fig. 1-2, the present invention provides a double-wall corrugated pipe with a peak staggering structure, which comprises an inner layer 1 and an outer layer 2. The inner layer 1 is of a circular ring tubular structure; the outer layer 2 comprises two semi-annular pipe fittings which are connected into a complete annular structure, the outer layer 2 is coaxially arranged on the outer peripheral surface of the inner layer 1, the semi-annular pipe fittings are provided with a plurality of convex wave crest parts which are arranged side by side along the axial direction, the convex wave crest part a21 is arranged on one semi-annular pipe fitting, and the convex wave crest part b23 is arranged on the other semi-annular pipe fitting; in the first semi-annular pipe fitting, a wave valley part a22 is formed between any two adjacent wave peak parts a21, and in the second semi-annular pipe fitting, a wave valley part b24 is formed between any two adjacent wave peak parts b23; the wave crest part a21 in the first semi-annular pipe fitting and the wave crest part b23 in the second semi-annular pipe fitting are distributed in a staggered mode, the deformation resistance of the corrugated pipe is guaranteed in different areas, and the wave trough part a22 in the first semi-annular pipe fitting and the wave trough part b24 in the second semi-annular pipe fitting are distributed in a staggered mode, so that soil can be filled through the different areas.
This embodiment improves the ring stiffness to improve burying stability and deformation resistance. After the corrugated pipe is buried underground, soil is filled in the wave trough parts of the semi-annular pipe fittings, the position stability of the corrugated pipe buried underground can be effectively improved due to the two rows of wave trough parts which are distributed in a staggered mode, the integral ring stiffness of the corrugated pipe is improved, the corrugated pipe is not prone to deformation under the soil pressure and breakage, the buried corrugated pipe is better in safety, and the service life is longer.
Example two
As shown in fig. 1-2, the utility model provides a peak shifting structure double-walled bellows compares in embodiment one, in this embodiment, a plurality of crest portion equidistance in the same semi-annular pipe fitting distribute, a plurality of crest portion a21 equidistance distribute promptly, and a plurality of crest portion b23 equidistance distribute, and the structure is more regular, is convenient for produce and process.
