SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is to the problem that exists among the background art, provides a double-deck ripples structure wall pipe that folds of stability when having improved underground.

The technical scheme of the utility model is a double-layer wave-stacked structure wall pipe, which comprises an inner pipe and an outer pipe;

the inner pipe and the outer pipe are of a rotary structure, the outer pipe is coaxially arranged on the peripheral surface of the inner pipe, the outer pipe is provided with a plurality of wave crest portions protruding outwards along the radial direction, the wave crest portions are arranged side by side along the axial direction of the outer pipe, wave trough portions are formed between adjacent wave crest portions, and the cross section formed by cutting the wave crest portions by a plane passing through the central shaft is in a tower shape.

Preferably, the edges of the wave crest part and the wave trough part are provided with chamfers.

Preferably, the wave crest part is provided with a plurality of step surfaces, the step surfaces are annular surfaces, and the step surfaces are symmetrically distributed.

Preferably, the step surface is a circular ring surface, and the diameters of the step surfaces distributed along the direction from the middle part to the two sides are gradually reduced.

Preferably, the step surface diameter gradually increases in a direction away from the middle of the peak portion.

Preferably, a cavity is formed between the outer peripheral surface of the inner pipe and the inner side surface of the wave crest part.

Compared with the prior art, the utility model discloses following profitable technological effect has:

the utility model provides high stability when burying underground. A plurality of crest portions are arranged side by side, the crest portions are cut along a plane passing through the central shaft to form a tower-shaped section, multiple layers of steps are formed, soil can be filled in each step of the tower-shaped section, each step can be limited by the soil, stability of the buried pipeline is improved, and the pipeline is not prone to position deviation.

Detailed Description

Example one

The utility model provides a double-deck ripples structure wall pipe that folds, including inner tube 1 and outer tube 2. As shown in fig. 1-2, the inner tube 1 and the outer tube 2 are of a rotary structure, the outer tube 2 is coaxially disposed on the outer circumferential surface of the inner tube 1, the outer tube 2 has radially outwardly convex crest portions 21, the crest portions 21 are disposed side by side in the axial direction of the outer tube 2, crest portions 22 are formed between adjacent crest portions 21, and the crest portions 21 have a tower-like cross section formed by cutting a plane passing through the central axis.

This embodiment improves the stability at the time of burying. The plurality of crest portions 21 are arranged side by side, the crest portions 21 are cut along a plane passing through the central shaft to form a tower-shaped section, a plurality of layers of steps are formed, soil can be filled in each step of the tower shape, each step can be limited by the soil, stability when a pipeline is buried is improved, and the pipeline is not easy to shift in position.

Example two

The utility model provides a double-deck ripples structure wall pipe that folds compares in embodiment one, and the difference of this embodiment and embodiment one lies in, and wave peak portion 21 and wave trough portion 22 edge all are provided with the chamfer, avoid stress concentration, improve life.

A cavity is formed between the outer peripheral surface of the inner tube 1 and the inner side surface of the crest part 21, so that the material amount used is saved, and the production cost is saved.

EXAMPLE III

The utility model provides a double-deck ripples structure wall pipe that folds, compare in embodiment one, in this embodiment, as shown in FIG. 2, ripples peak portion 21 has a plurality of step faces 211, step face 211 is the annular face, a plurality of step faces 211 symmetric distribution, the step face 211 that is located ripples peak portion 21 crest is the farthest away from the distance of ripples peak portion 21 center pin, a plurality of step faces 211 that distribute to both sides direction along ripples peak portion 21 are more and more nearly to the distance of crest portion 21 center pin, thereby form the echelonment structure, can obtain spacing when filling soil in radial a plurality of regions.

Example four

The utility model provides a pair of double-deck ripples structure wall pipe that folds compares in embodiment one, in this embodiment, as shown in FIG. 1, step face 211 is the torus, and the diameter of a plurality of step faces 211 that distribute along middle part to both sides direction reduces gradually, and the torus workable, the surface is regular.

EXAMPLE five

The utility model provides a pair of double-deck ripples structure wall pipe that folds, this embodiment lies in with embodiment four's difference, and step face 211 diameter is along keeping away from ripples peak portion 21 middle part direction crescent to enable step face 211 and lean on interior one end indent, form and sink, soil is filled after the inside, further obtains improving to the spacing effect of pipeline.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
