Cast-in-place box culvert molds are specialized forming tools for on-site concrete pouring, featuring modular design and high-strength structures. Compatible with circular, rectangular, and custom cross-sections, they enable rapid assembly, precise positioning, and reusability. Ideal for municipal utility tunnels, transportation culverts, and hydraulic projects in complex geological conditions, these molds meet large-volume and irregular structural needs with flexibility and efficiency.
Usage
Casts concrete box culverts (circular / rectangular / multi-cell) for urban drainage systems, underpasses, and utility tunnels. Suitable for overburden depths ≥15m and complex geology (soft soil / rock layers), ensuring structural integrity and seismic resistance.
Key Applications
Municipal
Drainage culverts in rugged terrain, utility tunnel extensions.
Transportation
Mountain highway culverts, tunnel passageways, bridge footings.
Hydropower
River interception culverts, reservoir diversion tunnels, flood control systems.
Industrial
Chemical plant basins, power plant cooling channels, equipment foundations.

Key Features
Modular Flexibility
Configurable for circular / rectangular / multi-cell structures. Adapts to variable cross-sections (e.g., tapers, flared ends).
01
Rapid Construction
≤1-hour assembly / segment (3x faster than wood forms). Hydraulic auto-leveling reduces labor.
02
High Precision
Ra≤1.6μm formwork surface eliminates plastering. 3D alignment ensures ≤3mm axis deviation and ±5mm elevation error.
03
Eco-Efficiency
300+ reuse cycles (80% wood saving). Prefab parts enable zero-waste sites (ISO 14001 compliant).
04
Safety
Steel supports spaced ≤1.5m (anti-tip factor ≥2.0). Fall-prevention devices for elevated work.
05
Target Clients
Municipal Engineering Contractors
Transportation Infrastructure Firms
