Introduction to PE drag pipe technology:
PE pipe pulling technology is a non excavation pipeline laying technology used in municipal construction. Its advantages are that it does not affect the surrounding environment or has little impact, the construction site is small, and the noise is low. Moreover, deep operations can be carried out underground, which is an unparalleled advantage of excavating and burying pipelines. But pipe jacking technology also has drawbacks, such as long construction time and high engineering costs.
The advantages of this technology are: no excavation of the ground, no demolition, no damage to ground buildings, no impact on traffic, no damage to the environment, no impact from climate and environment, no impact on pipeline deformation, time-saving, efficient, safe, and low overall cost. This technology is widely used in urban underground water supply and drainage pipelines, natural gas and oil pipelines, and non excavated communication cables in economically developed coastal areas of China. It can cross roads Railways, bridges, mountains, rivers, straits, and any buildings on the ground. Adopting this technology can save a lot of land acquisition and demolition costs, and reduce environmental pollution and road congestion has significant economic and social benefits.
PE drag pipe construction process:
The horizontal directional drilling rig used for pipeline crossing construction is generally divided into two stages: drilling as accurately as possible according to the design curve; The second stage is to expand the guide hole, and the product pipeline (usually PE pipeline, optical cable sleeve, steel pipe) is dragged back along the expanded guide hole to complete the pipeline crossing.
PE drag pipe connection process:
1. Electric fusion connection: Electric fusion connection. Electric fusion saddle connection;
2. Hot melt connection: Hot melt connection, hot melt saddle connection, and hot melt butt connection.
