6. •A slab culvert is a reinforced concrete structure
designed to facilitate the smooth flow of water
beneath roads or railways. Serving as a channel for
water drainage, slab culverts play a crucial role in
preventing flooding and enhancing transportation
infrastructure. These structures are characterized by
a flat horizontal slab supported by abutments or
walls, effectively managing water passage while
providing stability and durability.
INTRODUCTION

7. Culverts come in various types:
• Box Culvert:
Rectangular or square-shaped culvert with a bottom slab, two side walls, and a
top slab.
• Pipe Culvert:
Circular or elliptical pipes used to convey water beneath roads or railways.
• Arch Culvert:
Semi-circular or elliptical in shape with an arch-like structure.
• Slab Culvert:
Flat, horizontal structure supported by abutments or walls.
TYPES OF CULVERT

8. The primary purpose of slab culverts is to manage the efficient flow of water beneath
roads or railways. Key objectives include:
1.Water Drainage: Facilitate the smooth passage of water, preventing accumulation
and potential flooding.
2.Infrastructure Protection: Safeguard roads and railways from water-related damage,
ensuring structural integrity.
3.Traffic Continuity: Allow uninterrupted transportation by mitigating water flow
disruptions, contributing to safer and more reliable travel.
4.Erosion Prevention: Help prevent soil erosion around and beneath transportation
infrastructure, maintaining stability.
PURPOSE

9. CULVERT DESIGN
The design of slab culverts involves several key considerations to ensure
structural integrity and effective water management. Key design aspects include:
1.Structural Elements:
1.Slab Design: Thickness and reinforcement to withstand loads and
environmental conditions.
2.Abutments and Piers: Provide support and stability to the slab, considering
water flow forces.
2.Hydraulic Considerations:
•Water Flow Analysis: Evaluate anticipated water volumes and velocities.
•Inlet and Outlet Design: Optimize for efficient water entry and exit,
minimizing erosion risks.

10. 3.Geotechnical Factors:
1.Soil Bearing Capacity: Assess the soil's ability to support the culvert structure.
2.Foundation Design: Ensure a stable base for the culvert components.
4.Materials Selection:
1.Concrete Quality: Choose durable and weather-resistant concrete for longevity.
2.Reinforcement: Include proper reinforcement to enhance structural strength.
5.Environmental Impact:
1.Ecological Considerations: Minimize disruption to local ecosystems.
2.Sustainability: Implement eco-friendly design practices and materials when possible.

11. 6.Safety Measures:
1.Traffic Load Considerations: Account for vehicle loads and potential impacts on the
structure.
2.Pedestrian Safety: If applicable, incorporate features for safe pedestrian passage.
7.Regulatory Compliance:
1.Adherence to Codes and Standards: Ensure compliance with local and national
construction regulations.
2.Permitting: Obtain necessary permits for construction in accordance with
governmental requirements.

12. ESTIMATING AND COSTING OF SLAB CULVERT
The estimation and costing of any structure is defined as the process of
determination of quantities of items of work, and its cost for completion.
Estimate of a project is therefore, a forecast of its probable cost.

28. Conclusion: A culvert might go about as a bridge for traffic to pass on it
They are regularly tracked down in a natural flow of water and fill the purpose
of a bridge or a current flow regulator. Culverts are accessible in many shapes
like
round ,curved ,level-lined ,pear molded ,and box-like constructions.
Recommendation: The structural choice of a culvert and corresponding
inlet is based on environmental consideration, risk to property, cost of
construction and maintenance and also aesthetic considerations. The capacity
of an existing culvert can be increased with an improved inlet
