This embodiment stacks with traditional tubular product for example as shown in fig. 4, and required pipe pillow when this embodiment bellows carries out the multilayer and stacks need not to use circular bellows to stack, practices thrift the cost, makes tubular product lay can be more convenient and more efficient. The required ground excavation volume is small, and the compressive property is better.

Example 2

As shown in fig. 1, the corrugated tube of the present invention comprises: first connecting portion, second connecting portion, bellows main part 12, first connecting portion, second connecting portion are fixed the both ends of bellows main part 12, bellows main part 12 includes circular segment and square segment, circular segment with square segment connects in turn, includes at least one circular tube coupling 122 in every circular segment, includes at least one square tube coupling 121 in every square segment, circular tube coupling 122 is that the outer lane is a circular section body in the cross-section, square tube coupling 121 is that the cross-section outer lane is square, the cross-section inner lane is a circular section body, the length of a side of square tube coupling 121 outer lane is more than or equal to the diameter of circular tube coupling 122 outer lane, bellows main part 12 center is cylindrical through-hole.

Because the corrugated pipe adopts the structure that the square pipe joints 121 and the circular pipe joints 122 are alternately arranged, and the circular pipe joints 122 are smaller than the square pipe joints 121, namely, the cross sections of the circular pipe joints 122 are contained in the cross sections of the square pipe joints 121, when the corrugated pipe main body 12 is bent, the pipe joints are not easy to collide, and the bendable allowance is larger, so that the corrugated pipe in the embodiment has a larger bendable range compared with the existing circular corrugated pipe.

The four corners of the square pipe joints 121 are all in a chamfered structure, the square section comprises two square pipe joints 121, and the round section comprises one round pipe joint 122. The bellows main body 12 is made of polymer, and in this embodiment, the bellows main body 12 is made of high density polyethylene.

The first connecting portion and the second connecting portion are socket structures, each socket structure comprises a socket 11 and a socket 13, the socket 11 and the socket 13 are respectively located at two ends of the corrugated pipe, a convex point 111 is arranged on the outer surface of the socket 11, an L-shaped notch 131 is arranged on the socket 13, and the socket 11 and the socket 13 are connected and installed as shown in FIG. 3.

In this embodiment, the protruding point 111 is hemispherical, as shown in fig. 5, the L-shaped notch 131 is provided with a bayonet 132, the width of the L-shaped notch 131 at the bayonet 132 is smaller than the width of the protruding point 111, when the socket 11 is rotated and fixed with the socket 13, the protruding point 111 is screwed through the bayonet 132 in an interference manner, the protruding point 111 of the socket 11 is clamped with the L-shaped notch 131 of the socket 13 through the narrowed bayonet 132 on the L-shaped notch 131, and the socket 11 is tightly connected with the socket 13.
