A box culvert is a box-shaped concrete structure placed underground beneath roadways to allow rainwater, storm-water runoff, or natural streams to flow freely without disrupting surface vehicular movement.

At Harihar Chowk, the existing drainage channel was prone to overflow during heavy monsoon spells. Additionally, older culvert structures lacked the load capacity to support Rajkot’s expanding vehicular traffic. The upgrade involves:

• Reinforced Concrete (RCC) Box Construction: Replacing old, narrow pipe culverts with heavy-duty rectangular concrete boxes built to handle high water volumes and heavy vehicle loads.
• Underground Channel Expansion: Widening the internal water channel to prevent urban flooding and waterlogging during intense rainfall.
• Surface Road Reconstruction: Applying high-density asphalt layers over the culvert deck to align it smoothly with adjoining roads, creating wider, safer junction turns.

Background Information

Harihar Chowk sits at the heart of Rajkot’s older commercial core, surrounded by bustling market zones, retail outlets, banks, and administrative centers. For years, the intersection faced a dual challenge: severe traffic bottlenecks during rush hours and localized waterlogging during monsoon downpours.

           Final Phase: Asphalt Surfacing (Damarkam) & Full Road Reopening

When heavy monsoon rains struck the region, central drainage lines passing through Harihar Chowk were overwhelmed by high runoff volumes. Water overflowed onto the surrounding asphalt, causing pavement erosion, deep potholes, and traffic slowdowns.

To resolve these recurring issues, the Rajkot Municipal Corporation (RMC) commissioned a structural upgrade. Civil engineering teams excavated the intersection, replaced outdated pipe structures with precast and cast-in-situ RCC box culverts, reinforced the road foundation, and prepared the surface for final asphalt paving.

Key Highlights

• Final Construction Phase: Concrete box culvert installation at Harihar Chowk is structurally complete, with civil teams focusing on final surface integration.
• Asphalt Paving Underway: Asphalt surfacing (damarkam) is entering its final stage to create a smooth transition between the new culvert deck and existing approach roads.
• Relief for Thousands of Commuters: The reopening will clear daily congestion for thousands of two-wheelers, cars, auto-rickshaws, and delivery vans.
• Enhanced Drainage Capacity: The enlarged box culvert prevents rainwater accumulation at the junction, protecting nearby commercial properties.
• Full Connectivity Restored: Normal traffic routes through Harihar Chowk will resume shortly, ending multi-week detours and traffic diversions.

Detailed Explanation of the Event

1. The Engineering Process Behind Box Culvert Construction

Building an RCC box culvert at a busy urban junction like Harihar Chowk requires a precise, multi-stage engineering plan. Civil contractors began by diverting traffic and trenching deep into the intersection to reach the underlying drainage channel.

Workers built a solid base slab, poured high-strength reinforced concrete walls and top slabs (or installed pre-cast concrete box modules), and treated the structure with waterproof coatings to prevent groundwater seepage.

Rectangular RCC box culverts feature wider flat-bottom floors that allow higher water velocity, reducing silt buildup and making maintenance access easier for municipal sanitation crews.

Municipal engineers note that completing the asphalt surfacing with proper compaction ensures the road can handle high traffic volumes without developing surface cracks or structural sagging over time.

Challenges and Limitations

Executing major drainage construction at a central intersection presents several real-world challenges:

• Managing High Traffic Densities: Diverting thousands of vehicles through narrow alternative routes during construction creates temporary congestion on nearby secondary streets.
• Weather and Monsoon Dependencies: Heavy rainfall during the construction phase can fill open excavation trenches with water, delaying concrete curing and asphalt paving.
• Underground Utility Networks: Excavating central junctions requires careful coordination to avoid damaging existing water pipelines, power lines, telecommunications conduits, and gas mains.

Future Outlook

The completion of the Harihar Chowk project aligns with the Rajkot Municipal Corporation’s broader commitment to upgrading city infrastructure:

• Citywide Drainage Modernization: Successful box culvert installations at high-density intersections serve as a model for replacing aging pipe culverts in other flood-prone wards across Rajkot.
