Steel band reinforced plastic drainpipe and method and apparatus for manufacturing the same

Abstract

This invention relates to a steer tape reinforced plastic drainpipe including a plastic pipe and a reinforcing rib integrated with the pipe, and inside the rib compounds the steer tape. The method for making said plastic drain-pipe comprises the following steps: 1, compounding the steer tape with the plastic to form the special section with the reinforcing rib; 2, transporting the special section to the installing place; 3, binding and fusion welding the section to form the steer tape reinforced plastic drain-pipe; 4, setting the plastic bell-and-socket joint in the drainpipe port, then fusion welding it to form the continuous drainpipe.

Description

technical field

[0001] The invention relates to a steel belt reinforced plastic drainage pipe and its manufacturing method and device. Specifically, steel strips and plastics are compounded to form special-shaped strips on the composite device, and then the compounded special-shaped strips are wound and formed into steel strip-reinforced plastic drainage pipes on a special winding device. Background technique

[0002] Existing plastic drainage pipe is a kind of pressureless drainage pipe. In order to save the consumption of raw materials and ensure the ring stiffness of the pipes during use, various plastic drainage pipes with different structures have been invented. For example, double-wall corrugated pipe, hollow winding pipe. Plastic structural wall pipes are relatively mature drainage pipes commonly used at present, and are much lighter than solid-wall plastic pipes. However, the above-mentioned pipes must be produced in the factory, and then transported to the install...
