Stesen Pencampuran Tanah Terstabil WBZ800 dalam Projek Peluasan Lebuhraya G70

Garis Besar Projek

In this WBZ800 case study, we explore the G70 Highway Expansion Project, a critical infrastructure initiative in Northwest China, which involved extending a 120-kilometer section through challenging terrain with highly variable soil quality. The primary challenge was constructing a stable, durable, and cost-effective road base capable of withstanding heavy traffic and extreme seasonal weather fluctuations. The project required a high-volume, consistent supply of high-quality cement-stabilized aggregate for the sub-base and base courses.

Cabaran

Kaedah tradisional pemantapan tanah yang menggunakan beberapa loji pengadukan terpisah menimbulkan isu logistik dan kawalan kualiti yang ketara. Projek ini menghadapi tarikh akhir yang ketat, lokasi terpencil, dan spesifikasi kejuruteraan yang ketat yang menuntut ketepatan pengadukan ±1.5% bagi kandungan air dan ±0.5% bagi dos simen. Pengadukan yang tidak konsisten akan menyebabkan bahagian yang lemah, kemungkinan penurunan, dan pembaikan masa depan yang mahal, membahayakan jadual dan bajet projek.

The Solution: Stesen Pencampuran Tanah Terstabil WBZ800

As detailed in this WBZ800 case study, the project’s lead contractor selected the equipment as the central mixing plant for the entire operation. This stationary, continuous mixing plant was chosen for its renowned reliability, massive output, and precision.

Pelaksanaan dan Kelebihan Teknikal dalam Tindakan:

1. High Efficiency & Output: The WBZ800’s continuous mixing technology delivered a theoretical output of 800 tons per hour. This immense capacity allowed the project to complete the soil stabilization phase weeks ahead of schedule, as the single station could keep pace with the rapid advancement of the paving teams.
2. Unmatched Mixing Homogeneity: The plant’s twin-shaft mixing paddle design ensured a thorough and uniform blend of soil, cement, and water. This resulted in a consistently high-quality stabilized material with excellent mechanical properties. Subsequent core sample tests confirmed that every batch met the project’s rigorous compressive strength requirements.
3. Precision Batching System: The integrated computer-controlled batching system was pivotal. Its high-precision sensors and actuators meticulously measured and delivered the exact proportions of each material. This eliminated waste of expensive binding agents like cement and guaranteed the specified water-to-cement ratio, directly contributing to the structural integrity of the road base.
4. Durability in Harsh Conditions: A key takeaway from this WBZ800 case study is how the equipment operated reliably in a dusty environment with significant temperature variations. Its robust construction and sealed components minimized downtime for maintenance, ensuring an uninterrupted supply of material.

Keluaran dan Manfaat Projek:

• Accelerated Timeline: The project’s soil stabilization phase was completed 25% faster than originally planned.
• Significant Cost Savings: Reduced fuel and transportation costs from a centralized setup, along with minimized material waste due to precise batching, led to a direct reduction in overall project costs.
• Superior Quality Assurance: The consistent quality of the mixed soil eliminated weak spots in the road base, ensuring long-term durability and reducing lifetime maintenance costs for the asset owner.
• Enhanced Environmental Compliance: The plant’s efficient mixing process and dust collection systems minimized airborne particles, helping the project adhere to strict environmental regulations.

Kesimpulan

To conclude this WBZ800 case study, the successful deployment on the G70 Highway project underscores the equipment’s value as a cornerstone for large-scale, high-standard infrastructure construction. It proved to be more than just mixing equipment; it was a strategic asset that guaranteed quality, efficiency, and cost-effectiveness, setting a new benchmark for future projects.
