Small Diameter Pipe Underground Installation Work "Top Mall Method"
The "Top Mall Method" allows for extensive underground excavation without digging, enabling the installation of various communication cables, gas pipes, and plumbing for water supply and drainage. It also shortens construction time!
The Top Mall Method (Small Diameter Boring Method) is a non-excavation construction method for the installation of buried pipelines using a drill boring machine. It is suitable for construction in locations where excavation is difficult, such as national roads and railway tracks, and is a clean and simple boring method that does not produce excavated soil due to its non-excavation nature. Additionally, it is equipped with a directional correction boring method. 【Features】 ■ Boring Direction Correction Function: Curved boring is possible (Type M primarily focuses on straight boring) ■ Detection of Leading Drill Head: Can recognize angles, ensuring high safety and reliability ■ Compaction Method: No ground subsidence occurs due to the non-excavation method ■ Short Construction Period: Approximately 30m to 50m per day per location, depending on soil type, pipe size, and working environment ■ No significant traffic disruption, allowing for daytime construction ■ Environmentally friendly clean method that does not produce industrial waste due to the absence of excavation *For more details, please download the PDF or contact us.
