Abstract
The invention discloses a corrugated pipe with novel steel sheets. The corrugated pipe comprises an outer pipe and an inner pipe, and annular wavy structures uniformly distributed are formed between the outer side wall of the inner pipe and the inner wall of the outer pipe. The corrugated pipe is characterized in that compression resistance structures are installed in the annular wavy structures and are annular supports with the cross sections shaped like the letter D, and the annular wavy structures are filled with reinforced thermoplastic material. According to the invention, the compression resistance of the corrugated pipe can be improved, the corrugated pipe can be prevented from being damaged by external force, and the service life of the corrugated pipe can be prolonged; layering does not occur between the outer pipe and the inner pipe, and influence to normal use of the corrugated pipe is avoided; the compression resistance structures are arranged to be the annular supports of a D shape, the annular supports avoid edge angles, and therefore the inner wall of the corrugated pipe is prevented from being damaged.
Description
Technical field
The present invention relates to a kind of bellows drainpipe, especially a kind of bellows drainpipe with novel steel disc.
Background technique
Existing drainage pipe has employing metal tube respectively, Cement Concrete pipe and plastic film capicitor, using metal tube as waste pipe, are that the price of metal is very high on the one hand, the cost of metal tube is high, quality is large, and inconvenience is very installed in transport, on the other hand, metal tube contacts with water for a long time, metal is easy to get rusty, and makes metal tube not only very short for service life like this, and the metal tube damaged is difficult to change; Also have and adopt Cement Concrete pipe as waste pipe, Cement Concrete pipe be by concrete in a mold shaping come manufacture, although the manufacture cost of such Cement Concrete pipe is more cheap than metal, but the quality of Cement Concrete pipe is still very large, make the transport of Cement Concrete pipe and install very inconvenient, and the strength ratio metal tube of Cement Concrete pipe is poor; Therefore, have employed plastic film capicitor at present and replace metal tube and Cement Concrete pipe, the cost of plastic film capicitor is relatively low, and most importantly the quality of plastic film capicitor is little, easy transportation and installation, can save the more Pipe installing time and save more labour costs.But it is many that difference compared by existing plastic ripple pipeline intensity and metal tube and Cement Concrete pipe, therefore in use, especially the plastic film capicitor of underground is embedded in, the gravity of the earth covered on pipeline can be subject on the one hand, also can be subject to the impact force that earth sedimentation causes plastic film capicitor on the other hand, plastic film capicitor is easily destroyed, and the compression resistance of plastic film capicitor is bad, makes the serious curtailment in working life of plastic film capicitor; In order to the intensity of reinforced plastic bellows, plastic film capicitor is set to two-layer structure, but because the contractibility of two-layer material is variant, cause plastic film capicitor that the situation of layering easily occurs, affect the working life using and shorten waved plastic pipe of plastic film capicitor; Add the existing triangular supports arranged in bellows, leg-of-mutton drift angle can cause damage to bellows, affects the working life of bellows.
Summary of the invention
For the problems referred to above of the prior art, the present invention proposes a kind of bellows with novel steel disc, solve plastic film capicitor crushing resistance poor, outer tube and the easy layering of interior pipe, the technical problems such as working life is short.
Technological scheme of the present invention is: the bellows with novel steel disc, comprises outer tube and interior pipe, forms the ring-type wavelike structure be evenly distributed between the outer side wall of described interior pipe and outer tube wall; Be provided with compression-resistant structure in described ring-type wavelike structure, the annular support of described compression-resistant structure to be cross section be D font, is filled with enhancement thermoplastic material in described ring-type wavelike structure.
Further, the horizontal edge of described annular support is near the outer side wall of interior pipe, and the arc-shaped side of described annular support is near the Inner sidewall of outer tube.
Further, described enhancement thermoplastic material is glass fiber reinforced polypropylene or fibre reinforced polypropylene or nylon material etc.
Compared with prior art, the invention has the beneficial effects as follows:
1. in the present invention, the annular support that cross section is D font is installed in ring-type wavelike structure, can be good at increase bellows compression resistance and support effect, the cambered surface of D font structure can not cause damage to bellows simultaneously, prevent external force from causing damage to bellows, increase the service life of bellows.
2. cross section is selected to be the annular support structure of D font in the present invention, the structure of annular support is simple, easily manufactured, while ensure that good resistance to compression and support effect, saved manufacture annular support raw material, because this reducing the manufacture cost of whole bellows.
3. the present invention fills reinforced thermoplastic material in ring-type wavelike structure, can the compression resistance of bellows further, inner and outer tubes can be connected closely, prevent the phenomenon of inner and outer tubes generation layering, and reinforced thermoplastic material can by ring-type wave structure stable for annular support, annular support can not be slided, ensure that annular support strengthens the good crushing resistance of bellows.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the technological scheme in the present invention is further illustrated.
With reference to accompanying drawing 1, the present invention includes: outer tube 1 and interior pipe 2, between the outer side wall of interior pipe 2 and outer tube 1 inwall, form the ring-type wavelike structure be evenly distributed; In ring-type wavelike structure, compression-resistant structure is installed, increases the compression resistance of whole bellows, prevent external force from causing damage to bellows; The annular support 3 of compression-resistant structure to be cross section be D font, the structure of annular support 3 is simple, easily manufactured, save the raw material manufactured, thus also can reduce the manufacture cost of bellows, in ring-type wavelike structure, be filled with enhancement thermoplastic material 4, while the compression resistance increasing bellows further, interior pipe 2 and outer tube 1 can also be connected closely, prevent bellows generation layering, affect the normal use of bellows; Well annular support 3 can also be fixed in ring-type wavelike structure, ensure that annular support can realize good compression resistance.
The horizontal edge of annular support 3 is near the outer side wall of interior pipe, the arc-shaped side of annular support 3 is near the Inner sidewall of outer tube 1, on the outer side wall being fixed on interior pipe 2 making the horizontal edge of ring support 3 stable like this, the arc-shaped side of ring support and the area of contact of outer tube 1 inwall large, make ring support 3 can bear extraneous pressure uniformly, and the ability of bearing pressure is larger; Make the stability of annular support 3 better like this, also make the crushing resistance of bellows stronger.
Enhancement thermoplastic material 4 is glass fiber reinforced polypropylene or fibre reinforced polypropylene or nylon material etc., and the price of this several reinforced thermoplastic material 4 is relatively low, easy to process, and nontoxic.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
