Stormwater Solutions for Deep Burial Applications

High-Lateral Load Geocellular Systems For Urban Underground Spaces

Deep burial installations (4-6 meters) in urban underground spaces require stormwater management systems with exceptional lateral load capacity to withstand significant soil lateral pressures while maintaining high load-bearing performance.

Lateral Load Capacity: Over 45 Tons

The YYRH-MR-1000-HD series modules are engineered specifically for deep burial applications, with soil lateral pressure as a primary structural design consideration.

Vertical Load Capacity: Over 85 Tons

Maintains full structural integrity while bearing surface traffic loads from heavy-duty vehicles at burial depths of 4 to 6 meters.

Porosity: 90%–92%

High porosity maximizes rainwater storage volume within constrained urban right-of-way corridors.

Design Life: 50–60 Years

The molecularly modified polypropylene structure delivers outstanding creep resistance, ideal for long-term underground buried installations.

Critical Challenges in Deep Burial Stormwater Management

Soil Lateral Pressure

Surface Load Transfer

Urban underground stormwater systems must transfer surface loads from vehicles, buildings, and infrastructure through the burial soil to the geocellular structure. Deep installations require careful engineering to ensure load distribution does not exceed structural capacity.

Application Scenarios

0101

Urban Street Stormwater

Beneath city streets and roadways, deep burial stormwater systems manage stormwater from urban catchments while maintaining pavement structural integrity. Lateral load capacity addresses soil pressures from street excavations and adjacent foundations.

0202

Underground Parking Drainage

Subsurface parking structures utilize deep burial drainage systems beneath structural slabs where lateral load capacity and long-term durability are essential.

0303

Metro and Transit Infrastructure

Railway stations, metro systems, and transit facilities require deep burial stormwater management with proven lateral load performance for track bed and platform drainage.

0404

Utility Corridor Drainage

Utility tunnels and service corridors require stormwater management for equipment spaces and maintenance access areas.
