Precast Concrete Box Culvert

Product Description:

Our precast reinforced concrete Box Culverts provide a robust and efficient solution for various drainage, crossing, and conduit needs in Malaysian infrastructure projects. Manufactured under controlled factory conditions according to Malaysian Standards (e.g., MS 881), these units ensure consistent quality and rapid installation compared to cast-in-situ methods. Available in standard sizes and load classes, with options for integrated Dry Weather Flow (DWF) channels.

Key Features:

• Material: High-strength Precast Reinforced Concrete (Typically Grade G30/G40 or higher).
• Design Standard: Manufactured in compliance with relevant Malaysian Standards (MS 881) and/or JKR specifications (e.g., JKR/SPJ/...).
• Structure: Rectangular (box) shape, designed for earth and traffic loads.
• Dimensions: Available in a wide range of standard internal sizes (Width x Height x Length, e.g., 600x600mm up to 3000x3000mm or larger, standard lengths like 1m or 1.2m). Specify required size.
• Reinforcement: Steel reinforcement designed according to load class requirements (e.g., Class H, Class M).
• Joint Type: Typically Spigot & Socket or Rebated joints for effective connection and sealing.
• Variant Feature - Dry Weather Flow (DWF): Option available with an integrated low-flow channel at the base invert. This channel helps maintain water velocity during periods of low flow, reducing siltation and keeping the culvert cleaner. Select "With DWF" or "Without DWF" based on project needs.

Ideal for:

• Stormwater drainage systems under roads, railways, and embankments.
• Stream and small river crossings.
• Underground service conduits for utilities.
• Pedestrian or livestock underpasses.
• Attenuation tanks or channel systems.
• (DWF variant): Drains or streams with significant flow variation, ensuring self-cleansing during dry periods.

Benefits:

• Rapid Installation: Significantly reduces construction time compared to cast-in-situ culverts.
• Factory Quality: Consistent dimensions, strength, and finish due to controlled manufacturing.
• Durability: Designed for long service life under specified load conditions.
• Reduced Site Disruption: Minimizes on-site formwork, concrete pouring, and curing time.
• Structural Efficiency: Engineered design provides reliable load-bearing capacity.
• (DWF variant): Improved hydraulic efficiency and reduced maintenance in low-flow conditions.

Order our Precast Concrete Box Culverts for reliable and efficient drainage and crossing solutions! Specify internal dimensions, length, load class, and DWF requirement.

Important Notes:

• Site requires proper excavation and preparation of bedding material (sand/crushed stone).
• Requires appropriate lifting equipment (crane, excavator with lifting gear) for handling and installation. Use designated lifting points.
• Joints typically require sealant (e.g., bitumen compound, mastic strips, grout) as per project specifications.
• Delivery via crane lorry; ensure adequate site access.
