Large-aperture composite drainage pipeline

Abstract

The invention discloses a large-aperture composite drainage pipeline, and belongs to the technical field of pipelines. The large-aperture composite drainage pipeline comprises an inner wall pipeline layer, a flexible rigidity reinforcing layer, a main body pipeline layer and an outer wall pipeline layer which are sequentially bonded and wrapped from inside to outside, wherein the inner surface of the inner wall pipeline layer is a continuous smooth solid wall; a hole path which is spirally wound in the axial direction of a pipeline main body is formed in the pipeline main body layer, a water leakage sensing cable is installed in the hole path, and the water leakage sensing cable is electrically connected with a water leakage controller outside the drainage pipeline; and the outer wall pipeline layer comprises a high-density polyethylene base layer and a reinforcing steel belt which is spirally wound and compounded in the high-density polyethylene base layer. According to the large-aperture composite drainage pipeline, a plastic-steel composite structure with the combination of rigidity and softness is adopted, so that the large-aperture drainage pipeline has good rigidity, toughness and impact resistance, the problems of an existing large-aperture pipeline are solved, and meanwhile, a water leakage detection system is arranged, so that the effect of pre-alarming of pipeline water leakage is achieved.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a large-diameter composite drainage pipeline. Background technique [0002] With the continuous development of the urbanization process, the requirements for the urban underground pipe network system are getting higher and higher, especially in the living areas where the residents are concentrated. Big. As the caliber design increases, the requirements for the strength, rigidity, and impact resistance of the pipeline are also getting higher and higher. At present, there are usually two types of drainage pipes, metal pipes and plastic pipes. Although metal pipes have strong performance in terms of strength, rigidity, and impact resistance, they are weak in soil corrosion resistance and toughness, and are heavy. , transportation and installation are very time-consuming and labor-intensive; plastic pipes are usually PE pipes, which are hygienic, corrosion-resistant and easy to t...

AI Technical Summary

Problems solved by technology

Since large-diameter drainage pipes are generally buried deep underground, it takes a long time and is inefficient to manually check the leakage points, which is not conducive to quick repair work. At the same time, repairing after serious water leakage has also made maintenance difficult Increase, the sewage leaked from the water pipes will cause serious pollution to the soil, which is not conducive to environmental protection
