Jingzhou Huanggang steel wire mesh pipe, municipal water supply and drainage pipe

[Jingzhou Huanggang Municipal Water Supply and Drainage Pipeline Selection Core Requirements]

Jingzhou and Huanggang are located in the eastern part of the Jianghan Plain, with dense water networks and wide distribution of soft soil foundations. Municipal water supply and drainage pipe networks have long faced challenges such as soil corrosion, uneven foundation settlement, and short-term drainage pressure in the rainy season. Traditional cement pipes have too much weight and are easy to leak. Ordinary PE pipes have limited pressure-bearing capacity, making it difficult to adapt to the requirements of long-term stable operation of local projects. In recent years, steel mesh pipes have gradually become the mainstream selection.

The steel wire mesh pipe is reinforced with a high-strength steel wire winding layer as the skeleton, combined with the corrosion resistance of the polyethylene substrate, which can cover the pressure demand of 1.6MPa and below, and can meet the pressure requirements of large-flow water supply and drainage on the main road in the main urban area. The pipeline itself has certain flexibility, which can adapt to the uneven settlement of the local soft soil foundation within 3%, and is not prone to interface leakage problems. Under normal working conditions, the service life can reach 50 years, and the operation and maintenance cost is much lower than that of traditional pipelines.

[Core precautions for the construction of local steel wire mesh pipes]

The rainy season in Jingzhou and Huanggang is concentrated. Before construction, it is necessary to make a drainage plan for the trench in advance to avoid the foundation stability being affected by the soaking water in the foundation pit. Before the pipeline is laid, a 10-15cm thick fine sand cushion layer needs to be laid at the bottom of the trench to remove the sharp stones in the trench and avoid scratching the outer wall of the pipeline. The temperature needs to be strictly controlled between 210-230 ° C during hot melt connection. When the temperature is lower than 5 ° C in winter, the heating time needs to be appropriately extended. After the installation is completed, the closed water test needs to be carried out in accordance with the specifications. After the acceptance is qualified,

[Practical Suggestions for Local Project Selection]

When selecting the type, it is necessary to match the corresponding specifications according to the pipeline laying position and working pressure. The main pipe is recommended to choose the product with the pressure level adaptation. The branch pipe network can choose the conventional specifications according to the actual needs, and the compliance products that meet the national standard requirements are preferred to avoid improper material selection. Affect the service life of the pipe network.
