Production scenarios and design basis
Segmental bridge moulds are used in casting yards producing segments for span-by-span, balanced-cantilever and other approved erection methods. The mould concept follows the bridge alignment, segment family, casting curve, match-casting procedure, diaphragm and web arrangement, shear-key details, post-tensioning ducts and survey-control method.
Is this mould relevant to your project?
This mould type may be relevant when:
- Segment geometry, bridge alignment and erection method are defined
- Match casting, shear keys, ducts and survey points must be coordinated in one setup
- A short-line or long-line production method must be selected for the yard plan
- Repeated adjustment requires controlled references and positioning functions
Configuration directions
| Configuration direction | When it may be considered | Main review focus |
|---|---|---|
| Short-line mould system | Individual segments are cast against a controlled match-cast reference | Geometry control, bulkhead positioning, survey points and adjustment |
| Long-line mould system | Multiple segments follow an approved line and yard arrangement | Casting bed, alignment, segment sequence and handling space |
| Mechanical or hydraulic positioning | Repeated mould adjustment requires assisted movement | Stroke, reference system, controls, locking and maintenance |
Product performance and engineering features
- Bottom, side and bulkhead structures configured to the approved segment geometry
- Fixed and adjustable references for the selected short-line or long-line method
- Provisions for match-cast positioning and survey-control points
- Interfaces for shear keys, ducts, embedded items and lifting provisions shown on approved drawings
- Mechanical or hydraulic positioning functions selected for the agreed casting sequence
Final component tolerances and acceptance criteria remain subject to the approved project documents, production controls and applicable standards.
Required project inputs
Segment drawings, bridge alignment data, casting and erection methods, segment schedule, tolerance basis, duct and embedded-item details, target cycle, yard arrangement and survey procedure.
