Problems solved by technology
[0003] However, when the prestressed steel cylinder is used as a concrete rapid transportation pipeline, it needs to be buried underground, so the corrosion resistance of the mortar protective layer and high-stress cold-drawn steel wire is weak, and the steel cylinder is easy to be corroded. Resulting in a reduction in the service life of a concrete rapid transport pipeline with prestressed steel cylinders

The invention relates to the pipeline transportation field, in particular to a rapid transport pipeline made of concrete. The rapid transport pipeline made of the concrete comprises a steel cylinder and a cathode protection system, wherein the outer surface of the steel cylinder, along the extension direction of the steel cylinder, is provided with a conductive steel belt. The outer surface of thesteel cylinder is further provided with reinforcing steel bars, wherein the reinforcing steel bars are wound around the outer surface of the steel cylinder, and the conductive steel belt is located between the steel cylinder and the reinforcing steel bars. The conductive steel belt is electrically connected with the cathode protection system. The inner surface of the steel cylinder is provided with an inner protective layer, the outer surface of the steel cylinder is provided with an outer protective layer, and the outer protective layer covers the conductive steel belt and the reinforcing steel bars. According to the rapid transport pipeline made of the concrete, the outer surface of the steel cylinder is provided with the conductive steel belt, the conductive steel belt is electricallyconnected with the cathode protection system, so that the steel cylinder and the cathode protection system form a loop. When buried underground for conveying liquid, the rapid transport pipeline madeof the concrete is electrically connected with the cathode protection system to enable the steer cylinder to be in a cathode state, so that the corrosion of the steer cylinder can be blocked, thus prolonging the service life of the rapid transport pipeline made of the concrete.
Description
technical field [0001] The invention relates to the field of pipeline transportation, in particular to a concrete rapid transportation pipeline. Background technique [0002] A concrete rapid transportation pipeline is a pipe made of concrete or reinforced concrete, which is used to transport fluids such as water, oil and gas. A concrete rapid transportation pipeline in the related art is divided into a plain concrete rapid transportation pipeline, a common steel reinforced concrete rapid transportation pipeline, a self-stressed steel reinforced concrete rapid transportation pipeline and a prestressed steel cylinder concrete rapid transportation pipeline. Among them, the most widely used one is a concrete rapid transportation pipeline with prestressed steel cylinder, which includes a concrete rapid transportation pipeline core containing a steel cylinder, high-strength prestressed cold-drawn steel wire, and a mortar protective layer. The steel cylinder is made of thin steel...
