Rectangular cable trench mold are specialized formworks for mass-producing reinforced concrete cable trenches. Utilizing advanced design concepts and precision manufacturing, these molds enable flexible construction of various trench dimensions through standardized modular configurations, significantly enhancing production efficiency and product quality. They ensure dimensional accuracy (±2mm/m), structural stability, and easy installation. Available in two types - monolithic molds for standard applications and segmental molds for complex layouts - they are widely used in power engineering, municipal infrastructure, and industrial zones to meet modern cable laying and protection requirements.

Applications

Designed for manufacturing standardized rectangular cable trenches to accommodate power cables, communication lines, and integrated utility pipelines. Ideal for urban grid upgrades, industrial park power supply, and railway/highway cable laying. Engineered to withstand challenging terrains and climatic conditions, ensuring secure and stable cable operation.

Product Features

01/

Modular Design

The modular design enables rapid assembly / disassembly for easy transportation and storage. It supports flexible production of various trench sizes to meet diverse project needs. Precisely positioned embedded parts slots facilitate subsequent accessory installation.

02/

Reliable Quality

Rigorous QC processes guarantee dimensional accuracy (±2mm) and structural integrity (≥25MPa). Fully compacted concrete yields smooth surfaces (Ra≤3.2μm) without honeycombing. Excellent impermeability (P8-P10) ensures long-term durability.

03/

Efficient Production

Monolithic molds utilize vibration forming (≤40 minutes/unit), while segmental molds employ rapid-connection technology to slash production time. Special release agents ensure smooth demolding and prolong mold life.

04/

Precision Joints

Tongue-groove joints with single NBR gaskets (IP65) prevent water ingress. Tight connections maintain ≤3mm misalignment for superior sealing and stability.

05/

Rectangular Structure Advantages

Rectangular configuration maximizes space efficiency for organized cable layout / maintenance. Flat surfaces facilitate pavement restoration and landscaping.

Target Customers

Power grid construction firms (220kV+ projects)

Municipal engineering contractors (road / utility projects)

Industrial plant builders (factories / logistics parks)

Rail transit constructors (metro / light rail systems)

Infrastructure investors / operators (PPP projects)
