The reconstruction and expansion of Xiaohan Avenue, the construction link of MPP pipe supporting road electric power pre-burial

The reconstruction and expansion project of Xiaohan Avenue is a key project of regional traffic upgrading. The construction quality of road power pre-embedding is directly related to the stability of subsequent municipal power supply and long-term road use safety. In this link, MPP pipes have become the core supporting materials for power pipeline pre-embedding due to their strong adaptability, corrosion resistance and high strength.

In the early stage of construction, the technical team combined the geological conditions of road reconstruction and expansion with the regional power load demand to accurately plan the laying path and pipe diameter parameters of MPP pipes to ensure that the pipes fit perfectly with the original pipelines and new road structures. During the construction process, the directional drilling trenchless process was used to cooperate with MPP pipe laying to effectively reduce the interference to existing traffic, while avoiding the damage to the geological structure caused by traditional excavation construction, and speeding up the construction progress.

During on-site operation, the connection quality of MPP pipes is strictly controlled, and the hot-melt docking process is used to ensure that the interface is firmly sealed to prevent groundwater from infiltrating and affecting the operation of power pipelines. For the risk of heavy construction machinery rolling in road reconstruction and expansion, the high strength characteristics of MPP pipes can effectively resist external impact and ensure the structural integrity of pre-embedded pipelines.

In the later stage of construction, the technicians carried out strict stress testing and anti-corrosion testing on the pre-embedded section of the MPP pipe to ensure that the pipeline fully met the acceptance standards of municipal power engineering, and built a solid foundation for the normal power supply and smooth operation of the road after the reconstruction and expansion of Xiaohan Avenue.
