NOT DIGGING
1900
The United States has successfully implemented the pipe jacking method
A technological breakthrough in trenchless pipeline laying

From then on, at the construction level,
People have the possibility of “not digging”

01 What is trenchless construction?
Trenchless construction refers to a construction technology that does not excavate the road surface and can cross roads, railways, rivers, ground buildings, etc.,

and is widely used in urban pipeline laying.

Commonly used trenchless construction techniques include pipe jacking and pipe drawing. It has the advantages of safe construction, fast speed,

and does not affect ground traffic.

02 Our choice
ERA flexible self-locking polyethylene winding solid wall pipe (top-drawn pipe) uses polyethylene (PE) as the main raw material,

adding additives necessary to improve the pipe processing performance, and is a new type of pipe with a winding and forming structure that is highly adaptable.

Pipe jacking and pipe drawing construction.

Self-locking sealing structure
Multi-tooth dovetail rubber ring
Multi-layer winding process
Construction is quick and convenient

Self-locking sealing structure
The socket has high precision, good interchangeability, high connection strength, earthquake resistance and shear resistance, no disconnection,

and can adapt to uneven settlement.

Multi-layer winding process
Reduce the internal stress of the material and enhance the tear resistance of the pipe through spiral winding

and hot-melt connection.

Multi-tooth dovetail rubber ring
The rubber ring adopts a new conical inverted tooth frameless design for efficient sealing.

Construction is quick and convenient
The pipe is short in length, lightweight, flexible, and high in strength, and can be used in complex geology.

03 Future prospects
With the continuous improvement of urban construction, underground pipeline industry management departments are increasingly inclined to use trenchless pipeline technology.

Even in many first- and second-tier cities, trenchless engineering will be the only option.

ERA's flexible self-locking polyethylene winding solid-wall pipes (top-drawn pipes) will also gain a greater stage in trenchless projects such as community renovation,

old pipe replacement, sewage treatment, rail transit, etc.
