Pipe Local Repair - Six--sided Expander
Purpose
For rapid trenchless repair of localized pipe collapses.
Overview
The “six--sided expander” localized repair technology precisely positions the jacking equipment at the collapse site via traction. Hydraulically driven, six synchronously expanding jack plates uniformly apply radial force along the pipe circumference, restoring the collapsed section to its full circularity and original design inner diameter. This achieves structural rehabilitation of the existing pipe in a single operation.
Equipment Features
Six-sided Synchronization: Hydraulically driven expansion plates expand simultaneously at equal frequency and pressure, ensuring uniform circumferential force distribution on the pipe wall and preventing stress concentration.
Automatic Centering: The device automatically aligns with the pipe center during expansion, guaranteeing concentricity between the repaired section and the original pipe to prevent eccentric damage.
Comparative Advantages: Traditional “duckbill” methods expand symmetrically at only two points, causing excessive localized stress and pipe wall damage. Six-point radial expansion eliminates secondary damage risks entirely.
Adjustable Diameter: Modular replacement covers multiple specifications from DN200 to DN700, accommodating corrugated pipes, PE pipes, corrugated steel pipes, steel-reinforced pipes, spiral-wound solid-wall pipes, and thin-walled steel pipes.
Highly efficient and economical: Single-point repair eliminates the need for excavation or relining, significantly reducing labor and material costs.
Application Scope
Trenchless repair of localized collapses, deformations, and misalignments in corrugated pipes, PE pipes, corrugated steel pipes, steel-reinforced pipes, spiral-wound solid-wall pipes, and thin-walled steel pipes within urban underground water supply/drainage, gas, power, and communication networks.
