Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to 5, which are schematic structural views of the high density polyethylene double-wall corrugated pipe provided by the present invention. The double-walled corrugated hdpe pipe comprises an outer pipe 11, an inner pipe 12 disposed inside the outer pipe, and two connectors 13 disposed at two ends of the double-walled corrugated hdpe pipe, and the double-walled corrugated hdpe pipe further comprises other functional modules, such as lubricants, fillers, etc., which should be known to those skilled in the art, and will not be described in detail herein.
The outer tube 11 may be made of High Density Polyethylene (HDPE), and a plurality of corrugated rings 111 are axially spaced in parallel on the outer side wall of the outer tube 11, and the spacing distance between the corrugated rings 111 is the same. The corrugated ring 111 has a hollow structure and is internally provided with a reinforcing steel strip 112. The reinforced steel band 112 makes the corrugated ring 111 have high deformation resistance and can bear high pressure. The integral structure of the corrugated pipe can be better protected from being damaged when the corrugated pipe is used.
The inner tube 12 may also be made of High Density Polyethylene (HDPE), and the diameter of the outer sidewall of the inner tube 12 is slightly smaller than or equal to the diameter of the inner sidewall of the outer tube 11. It is conceivable that the outer tube 11 is formed in one piece on the basis of the inner tube 12. The connection between the inner pipe 12 and the outer pipe 11 is more compact, and the influence of bubbles generated during secondary molding fusion casting molding on the overall strength of the corrugated pipe is avoided. The inner tube 12 is solid and has smooth and non-radian inner side wall. So as to avoid the influence on the use performance caused by the sediment accumulated on the convex part during the drainage.
The interface 13 can be manufactured and assembled separately, or can be formed integrally with the inner tube 12 or the outer tube 11, so that the assembly steps are reduced. The interface 13 includes a first interface 131 disposed at one end of the double-walled bellows and a second interface 132 disposed at the other end of the double-walled bellows. The end face of the first interface is provided with a clamping groove 133 in a concave mode, and the end face of the second interface is provided with a clamping convex ring 134 in a protruding mode. The clamping convex ring 134 of one section of high-density polyethylene double-wall corrugated pipe is positioned in the clamping groove 133 of the other adjacent section of high-density polyethylene double-wall corrugated pipe, the clamping groove 133 is in clamping fit with the clamping convex ring 134 and can be fixed in a self-locking mode, and the connection stability among a plurality of double-wall corrugated pipes is improved. The opening of joint groove 133 is inboard and the terminal outside of joint bulge loop 134 all is equipped with the chamfer to convenience when improving the installation. Referring to fig. 2, the inner side of the root of the first connector 131 is provided with a first slope 135, the inner side of the root of the second connector 132 is provided with a second slope 136, the first slope 135 and the second slope 136 can prevent sand from being accumulated, and a buffer slope can be naturally formed after the first slope 135 and the second slope 136 are clamped with the clamping convex ring 134 to reduce the impact speed of water flow. And a metal locking ring 137 is further arranged on the outer side of the matching position of the clamping groove 133 and the clamping convex ring 134. The metal locking ring 137 enables the connection between the clamping groove 133 and the clamping convex ring 134 to be tighter, and can bear larger external pressure, so that the service life of the interface 13 is prolonged, and the interface has higher stability when uneven settlement occurs.
Compared with the prior art, the utility model provides a high density polyethylene double-walled bellows is through setting up joint bulge loop 134 cooperation on joint groove 133 on the first interface 131 and the second interface 132 has higher connection stability when the phenomenon of differential settlement takes place for the ground, avoids breaking and leaks. The corrugated ring made of HDPE material has high pressure resistance, light weight, high corrosion resistance and other features. The utility model discloses a simple structure, it is convenient to make, has higher practicality.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
