Steel Space Frame Installation

Installation of Large-span Space Frame Coal Shed Completed

The entire construction period is shortened by 15 days compared to traditional steel structures, and the on-site welding volume is reduced by 60% through factory prefabrication, and the welding quality pass rate is increased to 99.2%. This combination of structural system and construction method not only meets the functional requirements of large-span coal storage, but also takes into account construction efficiency and structural safety.

  • Project Value Summary

  • Overview of space frame coal shed

    Core parameters:
    Span: 138 meters (without intermediate support)
    Length: 420 meters
    Clear height: 32 meters (meeting bucket wheel machine operation)
    Coverage area: 58,000㎡ (coal storage capacity 350,000 tons)
    Steel consumption: about 8,200 tons
    • delivery fast
    • Installation period: 5-7 months

  • Key performance indicators

    Core parameters:
      Construction period: Total period 7.2 months (including foundation construction), 30% faster than similar projects. Dust suppression efficiency: Coal dust emission concentration ≤1.0mg/m³ (national standard limit 5mg/m³), environmental protection acceptance passed at one time. Storage and transportation efficiency: Railway loading speed 5,500 tons/hour, 160% higher than open-pit coal yard Economic efficiency, investment recovery period 4.8 years (including loss reduction/photovoltaic income) IRR＞18%,

  •  Environmental compliance: Completely solve the dust pollution caused by open-air coal storage and meet the rigid requirements of the Law on the Prevention and Control of Air Pollution;
     Cost reduction and efficiency improvement: Reduce coal loss by 87,500 tons per year (based on 350,000 tons of reserves), with direct economic benefits of 26 million yuan per year;
     Technical demonstration: Set the record of the largest span coal shed in North China, providing a model for the upgrade of Shanxi, Shaanxi and Inner Mongolia energy base.

    Next plan: Link railway loading system debugging, expected to be put into operation within 30 days, and annual coal turnover exceeding 12 million tons.

Four major technological breakthroughs

Efficient installation process

Adopting the "ground segmented pre-assembly + hydraulic synchronous lifting" technology (32 lifting points), the single lifting weight is 1,600 tons, the accuracy error is ≤3mm, and the construction period is shortened by 45 days compared with the traditional lifting.

Environmental performance meets the standard

Fully enclosed structure integrates intelligent spray dust suppression system (coverage rate 100%), the measured PM10 emission reduction is 92%, the coal dust loss rate is reduced to 0.25%, and the annual environmental protection benefit exceeds 8 million yuan.

Advantages of space frame

The grid space saves building materials, improves the space utilization rate of the coal shed, and is green and environmentally friendly.

Intelligent operation and maintenance pre-embedded

The grid is implanted with a fiber optic sensor network (spacing 10m), real-time monitoring of stress/deformation, and synchronously reserves the bucket wheel positioning track and photovoltaic bracket interface (installed capacity 2.1MW).
