Embodiment Construction

[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] see figure 2 , is a preferred embodiment of the plastic-steel winding pipe strip of the present invention, the strip is made of a metal profile 1 and a plastic body 2 coated on the surface of the metal profile 1, and the metal profile 1 and plastic The body 2 is compounded into one body with high resistance. The metal profile 1 includes a plurality of reinforcing ribs 10 with an "I" shape in longitudinal section, and the reinforcing ribs 10 are metal steel strips. The plastic body 2 is made of polyethylene plastic.

[0015] Each rib 10 includes a special...

Abstract

The invention provides a SRWPE tape, which comprises a metal profile and a plastic body. The plastic body covers the metal profile, which is provided with a reinforcing rib, and the reinforcing rib consists of an atypical profile and a stable profile, which is connected with the atypical profile; the surface of the SRWPE strip wall extends to form the reinforcing rib, which comprises the atypical profile connected with the wall surface of the pipe; the reinforcing rib also comprises a stable profile placed on outer part of the strip wall and connected with the atypical profile. The stable profile is added to the SRWPE strip, thereby ensuring that the ring steel stiffness standard is achieved, and reducing the height of the atypical profile to enable the height of the atypical profile to be smaller than the height of a straight rib steel strip with the same diameter and ring steel stiffness, and only has the atypical profile, thereby realizing high stability.

Description

【Technical field】 [0001] The invention relates to a plastic-steel winding pipe strip and a plastic-steel winding pipe made of the strip. 【Background technique】 [0002] Such as figure 1 As shown, the plastic-steel winding pipe is a plastic drainage pipe reinforced with a steel belt. Its strip structure metal profile and the plastic body 2' coated on the surface of the metal profile are composited. The metal profile includes a plurality of reinforcing ribs 1', A plurality of reinforcing ribs 1' are connected by a plastic body 2', the reinforcing ribs 1' are steel belts, and the plastic body 2' is made of polyethylene material. When the above-mentioned strips are wound into a plastic-steel winding pipe, the plastic body 2' constitutes the pipe wall, while the metal profiles extend outward from the pipe wall. [0003] In the above strip structure, the reinforcing ribs 1' are vertically arranged on the plastic body 2' connected between the reinforcing ribs 1'. Because the rin...
