Wuhan metropolitan area power channel construction MPP pipe jacking is widely favored

MPP pipe jacking is a special pipeline laying material prepared with modified polypropylene as the main raw material. It is mainly suitable for trenchless pipe jacking construction technology, and underground pipeline burial operations can be completed without large-scale excavation of road surfaces. At present, Wuhan metropolitan area is accelerating the upgrading of power infrastructure, and the number of new, reconstruction and expansion power channel projects has steadily increased. Trenchless construction has become the mainstream construction scheme for power channel construction due to its small interference to urban traffic and surrounding residents' lives. The corresponding MPP pipe jacking materials are widely used in various power construction projects due to their strong adaptability.

The core practical advantages of this type of pipe mainly include four points: First, the insulation flame retardant performance is up to standard and meets the safety requirements of power pipelines. The pipe itself has excellent insulation performance. The breakdown voltage under normal conditions is much higher than the rated voltage of conventional power pipeline operation. After adding compliance flame retardant components, the combustion performance meets the relevant standard requirements for public pipeline laying. It can effectively reduce the safety impact of the external environment on the operation of power lines. It is suitable for the buried laying needs of various power pipelines of 10kV and below. Second, the anti-deformation and anti-corrosion ability is outstanding, and it is suitable for complex underground working conditions. The ring stiffness of the pipe meets the relevant standards of municipal buried pipes, and can withstand the superimposed force of underground soil pressure and ground load. It is not easy to deform and crack when used for a long time. At the same time, it is resistant to acid and alkali and soil corrosion, and does not need additional anti-corrosion treatment. Under normal working conditions, the service life can reach more than 50 years. It is suitable for the construction environment along the river and the complex underground soil in Wuhan metropolitan area. The third is to adapt to the trenchless pipe jacking process to improve construction efficiency. The pipe surface has high smoothness, low friction coefficient, small resistance during jacking operation, and is not easy to cause pipe failure. The pipe interface adopts hot melt connection process, which has good sealing performance. There is no risk of leakage or disconnection during jacking, which can reduce the fault investigation time during the construction process, shorten the overall construction cycle of the project, and reduce the comprehensive construction cost. Fourth, the environmental protection performance meets the requirements and adapts to green construction standards. The pipe production process does not add harmful auxiliary materials, and no harmful substances will precipitate into the soil during laying and use. It can be recycled and reused after scrapping. It meets the relevant management requirements of green construction of municipal projects in Wuhan metropolitan area, and will not cause additional burden on the surrounding ecological environment.

This type of pipe is not only suitable for the construction of high-voltage power channels and the upgrading and transformation of distribution networks within the Wuhan metropolitan area, but also can be used for the buried laying of municipal communication pipelines, the renovation of urban old pipeline networks, and the construction of trenchless pipelines across rivers and sections. Suitable groups include power engineering construction units, municipal engineering construction units, pipeline project design units, pipe procurement and supply units, etc. All parties can choose products with corresponding specifications and parameters according to the pipeline burial depth, voltage level, and construction process requirements of specific projects.

At present, all performance indicators of this type of pipe are in line with the current product standards and construction specifications of the state and the power industry. Before the product enters the market, it can provide third-party authoritative test reports as required, which can meet the bidding access requirements of various power channel construction projects in the Wuhan metropolitan area. In the future, it can also cooperate with relevant units to provide supporting services such as entry verification and technical parameter disclosure.
