Description
Technical Field
The utility model relates to the field of corrugated pipes, in particular to a double-wall corrugated pipe with different axial centers.
Background
The drainage pipe is divided into a plastic drainage pipe, a Concrete Pipe (CP) and a Reinforced Concrete Pipe (RCP), and the drainage pipe mainly takes the drainage tasks of rainwater, sewage, farmland irrigation and drainage and the like, and is particularly used for longitudinal and transverse drainage and water permeation of the expressway; the back of various retaining walls and side ditches of the expressway are vertically and horizontally drained; draining water from the tunnel and the underground passage; water supply and drainage of municipal works, water purification plants, sewage plants, refuse dumps and the like; drainage of green areas such as golf courses, sports grounds, parks, etc.; slope water and soil conservation is developed on hilly land; underground drainage of land preparation works, etc. Corrugated pipes are a type of pipes widely used in the field of drainage.
For the existing corrugated pipe, after the corrugated pipe is buried underground, the soil on the corrugated pipe can apply pressure to the pipeline, the pipeline is easy to deform, and the structural strength and the bearing capacity of the existing corrugated pipe are not strong.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide an eccentric double-wall corrugated pipe with high structural strength and strong bearing capacity, aiming at the problems in the background technology.
The technical scheme of the utility model is that the non-coaxial double-wall corrugated pipe comprises:
a circular tube-shaped inner tube;
the outer tube is arranged on the peripheral surface of the inner tube and comprises outer convex portions and wave trough portions, the outer ends of the outer convex portions are wave crest portions, the outer convex portions and the wave trough portions are arranged side by side along the axial direction of the inner tube, the wave trough portions are integrally formed with the inner ends of the two adjacent outer convex portions along the axial direction of the inner tube respectively, the wave trough portions are of a circular tube-shaped structure, the wave trough portions are coaxially arranged on the peripheral surface of the inner tube, the outline of the wave crest portions is circular, and the wave crest portions and the inner tube are arranged in an eccentric mode.
Preferably, when the corrugated pipe is embedded, the center axis of the outer contour of the wave crest part is positioned right above the center axis of the wave trough part.
Preferably, the longitudinal section of the convex part comprises a circular arc structure and a linear structure connected to two ends of the circular arc structure.
Compared with the prior art, the utility model has the following beneficial technical effects:
the utility model has high structural strength and strong bearing capacity. In the outer tube, the wave valley portion is coaxial with the inner tube, and the wave peak portion is not coaxial with the inner tube, then the wave peak portion is compared in the inner tube and is the arch setting for the bearing capacity of the outer convex portion that has the wave peak portion is stronger. After the corrugated pipe is buried underground, the outer convex part has stronger capability of bearing soil pressure, higher structural strength and difficult deformation, so that the corrugated pipe can be more stably and firmly buried in the soil.

Detailed Description
Example one
As shown in fig. 1-2, the present invention provides an eccentric double-wall corrugated pipe, which includes an inner pipe 1 and an outer pipe 2.
The inner tube 1 is in the shape of a circular tube. The outer tube 2 is arranged on the outer peripheral surface of the inner tube 1, the outer tube 2 comprises outer convex parts and wave trough parts 22, the outer ends of the outer convex parts are wave crest parts 21, the outer convex parts and the wave trough parts 22 are arranged side by side along the axial direction of the inner tube 1, the wave trough parts 22 are integrally formed with the inner ends of the two adjacent outer convex parts along the axial direction of the inner tube 1 respectively, the wave trough parts 22 are of a circular tube-shaped structure, the wave trough parts 22 are coaxially arranged on the outer peripheral surface of the inner tube 1, the outer contour of the wave crest parts 21 is circular, and the wave crest parts 21 and the inner tube 1 are eccentrically arranged.
The embodiment has high structural strength and strong bearing capacity. In the outer tube 2, the wave trough part 22 is coaxial with the inner tube 1, and the wave crest part 21 is not coaxial with the inner tube 1, so that the wave crest part 21 is arranged in an arch shape compared with the inner tube 1, and the bearing capacity of the convex part with the wave crest part 21 is stronger. After the corrugated pipe is buried underground, the outer convex part has stronger capability of bearing soil pressure, higher structural strength and difficult deformation, so that the corrugated pipe can be more stably and firmly buried in the soil.
Example two
As shown in fig. 2, compared to the first embodiment, in the present embodiment, when the corrugated pipe is buried, the outer contour central axis of the crest portion 21 is located right above the central axis of the trough portion 22, that is, the end with the smallest depth of the trough portion 22 is disposed downward, the end with the largest depth of the trough portion 22 is disposed upward, and the position with the highest outward protruding degree of the outward protruding portion is disposed upward, so that the pressure-bearing capacity to soil is stronger, the structural strength is highest, and the corrugated pipe can be ensured to be in the most practical installation position.
EXAMPLE III
As shown in fig. 2, compared with the first embodiment, in the present embodiment, the longitudinal section of the external protrusion includes an arc-shaped structure and a linear structure connected to two ends of the arc-shaped structure, and the arc-shaped structure can uniformly bear force, so that soil can be guided to the valley portion 22 when soil is filled, thereby facilitating rapid burying of the corrugated pipe.
The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
