PE Replacement Pipe Usage: Construction workers did not excavate the entire road surface but instead created working pits at both ends of the construction pipeline. The surrounding walls of the pits were reinforced with cement. Once ready, a pipe bursting machine cuts the old pipeline fragments and pushes them into the surrounding soil to form pipe holes, while simultaneously pulling in a new pipeline (same or larger diameter) for pipeline replacement. This black technology, commonly known as "Static Pipe Bursting Method," has the following advantages compared to the traditional "cut and open" method: 1) Wide application range for pipelines (HDPE, steel, cast iron, cement), catering to the renovation of old and outdated pipeline facilities, meeting both structural upgrades and expansion needs; 2) Local excavation of working pits, making the pipeline replacement process simpler and more accessible, reducing road excavation and impact on public transportation; 3) Utilizing hydraulic equipment, resulting in low noise and minimizing disturbance to residents; 4) Small construction footprint, fast construction speed, short project duration, effectively reducing engineering costs, improving service performance, and benefiting the later maintenance of facilities.
