1. Project Overview
The Tanzania Tabora–Kigoma Standard Gauge Railway Project is a major railway infrastructure project in East Africa. The bridge section was supplied by Encofrado de acero Pansol, including custom cap beam steel formwork, cylindrical pier steel formwork and matching culvert flat formwork. Six truckloads of formwork were delivered in one consolidated shipment, achieving one-stop multi-product supply.
All formwork complies with JTG/T 3650-2020 Technical Specifications for Construction of Highway Bridges and Culverts, meeting the high requirements of overseas railway bridges for accuracy, rigidity and durability.
2. Key Formwork Requirements
Overseas railway bridges feature varying pier heights and spans, long-distance transportation and strict owner acceptance. The project set three core requirements:
- Dimensional accuracy: circularity of cylindrical piers and alignment of cap beams within design tolerances;
- Structural rigidity: resistance to lateral pressure from mass concrete pouring, preventing bulging and deformation;
- Efficient unified delivery: multi-specification formwork produced and delivered centrally to simplify the supply chain and meet schedule milestones.
3. Product Configuration & Technical Parameters
Cap Beam Steel Formwork
- Face plate: 6 mm Q235B national-standard steel plate
- Vertical walers: 10# standard channel steel, spacing ≤300 mm
- Tie system: M20 tie rods, overall safety factor ≥1.5
- Sealing: tongue-and-groove joint, misalignment ≤0.3 mm
- Finish: smooth cap beam surface, no leakage, meeting railway bridge acceptance standards
Cylindrical Pier Steel Formwork
- Forming process: CNC rolling one-step forming
- Circularity tolerance: ≤2 mm; diameter deviation: ≤±2 mm
- Stiffeners: circumferential gradient layout, spacing ≤400 mm in high-load lower zone
- Joint protection: double sealing strips, preventing leakage and honeycombing
- Application: high-pier concrete pouring, deformation-resistant under lateral pressure
Both product types undergo 1:1 pre-assembly inspection before shipment, with full verification of dimensions, hole positions and joints.
4. Project Value
- Unified quality standard: all products manufactured under the Pansol Steel Formwork national-standard system, avoiding quality inconsistency from multiple suppliers;
- Reduced communication cost: one supplier handles all formwork requirements, saving time and labor;
- Reliable delivery schedule: unified production planning and consolidated shipment match construction milestones and avoid delays from split deliveries.
5. Procurement Guidance for Overseas Bridge Formwork
- Avoid splitting purchases among multiple suppliers to prevent dimensional mismatch and on-site assembly errors;
- Never skip pre-delivery pre-assembly inspection — rectification on overseas sites is extremely costly;
- Reject low-price solutions using non-standard steel or thin face plates — the cost of bulging and rework overseas far exceeds that in China.
Encofrado de acero Pansol has 15 years of experience in road and bridge steel formwork. We provide one-stop export supply for full bridge-section formwork, from lower piers and footings to upper cap beams and box girders, catering to bulk procurement for large overseas projects.
