Direct Pipe Laying Machine for Trenchless Construction
Direct pipe laying machines utilize a trenchless construction method for installing pipelines. This method allows for simultaneous excavation and pipeline laying.
Technical Specifications
Overview
Advanced Trenchless Pipeline Installation
This direct pipe laying machine represents a new-type trenchless construction method where excavation and pipeline laying are performed simultaneously. It is specifically designed for high-efficiency projects involving small diameter water diversion, drainage, and oil pipelines. By combining a tunnel boring machine with a powerful pipe thruster, it eliminates the need for pipe installation during the drive and removes the requirement for reception shafts.
