Guangzhou Rectangular Jacking Pipe Segment Mould Project Overview

The rectangular pipe jacking method is a non-excavation tunneling technology used to construct large underground spaces. Compared with traditional methods such as open-cut excavation and shield tunneling, it offers several key advantages:

• Lower overall construction cost

• Minimal traffic disruption

• Environmentally friendly construction

Thanks to these benefits, the pipe jacking method has become an indispensable solution for municipal engineering, especially when crossing busy traffic lines, rivers, or areas with dense aboveground and underground structures.

Characteristics of Large Rectangular Jacking Pipe Segments

Large-diameter rectangular jacking concrete segments have unique engineering requirements:

• Extra-large cross-sectional dimensions and heavy self-weight

• High structural strength and precision standards

• Complex production process with strict quality requirements

• Built-in self-waterproof performance, durability, and adaptability to withstand jacking construction

These challenges make the mould system a critical part of ensuring segment quality, precision, and performance.
