Семь инженерных сценариев применения
Тяжелонагруженная инфраструктураПарковки, автомобильные дороги, портовые комплексы
Серия тяжелонагруженных модулей HD (класс нагрузки SL-Zh-8, предельная осевая нагрузка 85 тонн)
Глубина закладки 4–6 метров, рост затрат на бетонные конструкции (традиционные монолитные резервуары при глубине 6 м стоят в 2,3–4,1 раза дороже модульных систем), строительные работы с использованием кранов на стесненных городских участках.
Модули серии HD высотой 200 мм с коэффициентом пустот 92 %, усиленными ПЭ креплениями, геотекстилем плотностью 400 г/м², гидроизоляционной мембраной из HDPE толщиной 2,0 мм и чугунными люками класса D400. Монтаж осуществляется без применения кранов: бригада из двух специалистов за восьмичасовую смену собирает 40–60 модулей. Расчетный срок службы составляет 50 лет при глубине заложения до 8 м под циклическими нагрузками класса D400.

Traditional Cast-in-Place Reinforced Concrete Tank
- AspectDetail
- Construction methodExcavation → blinding → rebar fixing → formwork → concrete pour → 28-day cure → backfill. Total duration: 35-50 days for 500 m³. Requires crane for formwork and concrete skip.
- Cost at 5m burial2.3-4.1× modular system cost due to wall thickness escalation (500mm+ at 5m), double-layer rebar, and dewatering during construction.
- Void ratio100% (hollow tank — but unit cost per m³ stored is not comparable due to structural cost).
- Maintenance accessManhole only — limited visual inspection; structural defects (cracking, spalling) require confined-space entry.
- Carbon footprint250-350 kg CO₂e per m³ storage (cement is ~0.9 kg CO₂/kg).
Yingyuan Modular Geocellular System
- AspectDetail
- Construction methodExcavation → geotextile → liner (if detention) → module assembly → top geotextile → backfill. Total duration: 5-8 days for 500 m³ (4-person crew). No crane required.
- Cost at 5m burialBase cost. Lateral earth pressure carried by module columns; burial depth adds backfill material but not structural cost.
- Void ratio92% (module internal). System void ratio including perimeter: 90-92% typical.
- Maintenance accessCCTV via inspection riser — full internal surface visible; module-by-module replacement possible (top-down excavation to affected row).
- Carbon footprint40-60 kg CO₂e per m³ storage (virgin PP recycled at end-of-life; carbon benefit of avoided concrete).
System-Wide Advantages Why Modular Across All Seven Scenarios
Feature: Standardized Component Architecture
Across all three module series (HD, EW, SD), Module Dimensions and connection clip geometry are standardized. This means geotextile cutting plans, liner seam layouts, and connector clip logistics are identical regardless of which series is specified. Field crews trained on one series are immediately productive on any other. Spare parts inventory rationalization: 4 connector clip SKUs cover 3 module series across 7 scenarios. Operations benefit: site supervisors carry one reference dimension set; clip installation training is transferable; BOM generation logic is unified.
Feature: Void Ratio Advantage (92% Continuous)
At 92% void ratio, Yingyuan modules deliver 2-6% more storage volume per cubic meter of excavation than comparable geocellular systems (typical 90-92% void). For a 500 m³ storage requirement, this translates to 10-15 m³ less excavation — approximately 1-2 truckloads of spoil saved, with corresponding reduction in off-site disposal cost and carbon. The continuous (unbaffled) internal geometry also supports uninhibited CCTV inspection along any axis.
