ภาพรวมของโครงการ
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.
ความท้าทาย
วิธีการดั้งเดิมในการทำให้ดินมีเสถียรภาพ โดยใช้โรงงานผสมหลายแห่งที่กระจายอยู่ทั่วไป ก่อให้เกิดปัญหาด้านโลจิสติกส์และการควบคุมคุณภาพอย่างมีนัยสำคัญ โครงการต้องเผชิญกับกำหนดเวลาที่เข้มงวด สถานที่ห่างไกล และข้อกำหนดทางวิศวกรรมที่เข้มงวดซึ่งต้องการความแม่นยำในการผสมที่ ±1.5% ในปริมาณน้ำ และ ±0.5% ในปริมาณปูนซีเมนต์ การผสมที่ไม่สม่ำเสมอจะนำไปสู่ส่วนที่อ่อนแอ การทรุดตัวที่อาจเกิดขึ้น และการซ่อมแซมในอนาคตที่มีค่าใช้จ่ายสูง ซึ่งอาจทำให้โครงการล่าช้าและเกินงบประมาณ.
The Solution: สถานีผสมดินเสถียร 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.
การนำไปใช้และข้อได้เปรียบทางเทคนิคในการปฏิบัติ:
- 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.
- 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.
- 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.
- 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.
ผลลัพธ์และประโยชน์ของโครงการ:
- 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.
สรุป
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.
