Pipe rehabilitation using the Re-lining method involves repairing or restoring underground pipes without the need for extensive excavation. This approach includes inserting a new lining into the existing pipe to create a smooth and durable inner surface. The method effectively seals leaks, prevents corrosion, and enhances the structural integrity of the pipe. This process can minimize disruption to the surrounding environment, reduce costs, and significantly decrease the time required for pipe rehabilitation.

 

Additionally, Cured-In-Place Pipe (CIPP) Lining is considered to be one of the quieter trenchless rehabilitation methods, in contrast to the traditional "open, cut, and replace" method. The process involves pulling deflated soft liner fabric material into the host pipe using a winch. The liner is then inflated with compressed air to fit tightly within the host pipe. Finally, the liner is cured using steam until it cools down and hardens.

原位固化內襯修復法是指在無需大規模開挖的情況下修復地下管道。這種方法包括在現有管道內插入新的內襯，以創造光滑耐用的內壁。這種方法有效地密封了滲漏，防止進一步腐蝕，並增強了管道的結構完整性。這個過程可以最小化對周圍環境的干擾、降低成本，以及大大縮短管道修復所需的時間。

此外，固化內襯（CIPP）與傳統的【開挖、切割和更換】方法相比，被認為是相對較安靜的非挖掘式修復方法。過程包括使用絞盤將折疊過的軟襯料拉進主管道。然後以壓縮空氣使襯料膨脹並緊貼在主管道內。最後，使用蒸汽固化襯料直至其冷卻硬化。
