Container Gantry Crane (265 tonnes / 295 tonnes with payload)
OBJECTIVE
To stop differential settlement of crane rail foundations and, at specific locations, restore the foundations to their design position without interrupting crane operations.
TECHNOLOGY
Soil improvement using controlled hydrofracturing combined with high-precision foundation lifting (structural re-leveling) by means of the PolyJET® injection method.
MATERIAL
PolyJet FT structural expanding polyurethane resin for soil injection, with a reaction time of less than 30 seconds.
DESCRIPTION
The crane rail foundations experienced differential settlement, resulting in operational difficulties and posing risks to the continuity of the production process.
The key technical challenge was to ensure uniform deformation characteristics of the subgrade beneath the foundations. Certain sections had already undergone settlement and required lifting to the design elevation, while adjacent sections remained stable and required only stiffness enhancement to prevent future deformation.
All works had to be performed without suspending crane operations.
RESULTS
The foundations were stabilized through subsoil improvement, specifically by reducing compressibility and increasing stiffness under both static and dynamic loading conditions.
The crane rail foundations were re-aligned to the design position with an accuracy of less than 1 mm.
All works were carried out without interruption of production activities, during intervals between crane operations.
As a result, safe and uninterrupted operation of the heavy container gantry crane was fully ensured.
