Abstract
A double-walled corrugated pipe comprises a corrugated wall layer, connecting layers, corrugated spaces, a round pipe space and a round pipe wall layer, and is characterized in that: the round pipe space is an isodiametric space passage defined by the round pipe wall layer, the inner wall of the passage is smooth, so that the double-walled corrugated pipe can be conveniently used in construction in technical fields related to buildings, communication and agriculture, the corrugated wall layer is arranged on the outside of the round pipe wall layer, and is distributed in the corrugated form along the axial line of the round pipe space, the crests of the corrugated wall layer are raised away from the round pipe wall layer, the corrugated spaces are formed between the raised parts of the corrugated wall layer and the round pipe wall layer, the troughs of the corrugated wall layer are sunken toward the round pipe wall layer, and the connecting layers are arranged between the troughs of the corrugated wall layer and the round pipe wall layer. The double-walled corrugated pipe has the advantages that: since the double-walled corrugated pipe is provided with the connecting layers, the inner and the outer layers of pipe walls of the double-walled corrugated pipe are firmly combined, and thereby the overall compression strength is enhanced.
Description
Technical field
The utility model belongs to the tubing technical field, a kind of double-wall corrugated pipe with double-layer tube wall of more specifically saying so.
Background technique
At present, double-wall corrugated pipe is applied to association areas such as building, communication, agricultural just more and more with its excellent performance, the double-wall corrugated pipe of prior art generally is made up of inside and outside two-layer tube wall, form a cavity between its inside and outside two-layer tube wall, with the entire compression intensity of enhancing pipeline, but in use, inside and outside two-layer tube wall is usually thrown off easily, and do not have the purpose that strengthens pipeline entire compression intensity, bring hidden danger to the pipework construction.
Summary of the invention
In order to address the above problem, the utility model provides a kind of inside and outside two-layer tube wall in conjunction with firm double-wall corrugated pipe, the technical solution of the utility model is: described double-wall corrugated pipe is by the ripple parietal layer, tie layer, the ripple space, the pipe space, the pipe parietal layer is formed, it is characterized in that the pipe space is the isometrical space pipeline that is surrounded by the pipe parietal layer, inner-walls of duct is smooth, be convenient to building, communication, the construction of agricultural correlative technology field is used, the outer installment ripple parietal layer of pipe parietal layer, the ripple parietal layer is the corrugated distribution along the axial direction in pipe space, the crest place of ripple parietal layer is to pipe parietal layer outer lug, constitute the ripple space between the ripple parietal layer of convex portion and the pipe parietal layer, the trough place of ripple parietal layer is recessed to the pipe parietal layer, between the trough recess of ripple parietal layer and the pipe parietal layer tie layer is set.
Ripple described in the utility model space is characterized in that the ripple space is a ring-type, and its cross section is semicircle.
The beneficial effects of the utility model are that double-wall corrugated pipe has designed tie layer, and its inside and outside two-layer tube wall has strengthened entire compression intensity in conjunction with firmly.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is A-A cross-sectional view of accompanying drawing 1, in the accompanying drawing:
1. ripple parietal layer, 2. tie layer, 3. ripple space, 4. pipe space, 5. pipe parietal layer.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail, so that the public grasps implementation methods of the present utility model better, the utility model specific embodiment is: described double-wall corrugated pipe is by ripple parietal layer 1, tie layer 2, ripple space 3, pipe space 4, pipe parietal layer 5 is formed, it is characterized in that pipe space 4 is the isometrical space pipelines that surrounded by pipe parietal layer 5, the outer installment ripple parietal layer 1 of pipe parietal layer 5, ripple parietal layer 1 is the corrugated distribution along the axial direction in pipe space 4, the crest place of ripple parietal layer 1 is to pipe parietal layer 5 outer lug, constitute ripple space 3 between the ripple parietal layer 1 of convex portion and the pipe parietal layer 5, the trough place of ripple parietal layer 1 is recessed to pipe parietal layer 5, between the trough recess of ripple parietal layer 1 and the pipe parietal layer 5 tie layer 2 is set.
Ripple described in the utility model space 3 is characterized in that ripple space 3 is ring-type, and its cross section is semicircle.
The beneficial effects of the utility model are that double-wall corrugated pipe has designed tie layer 2, and its inside and outside two-layer tube wall has strengthened entire compression intensity in conjunction with firmly.
