Faced with the stringent concrete quality requirements of high-speed rail construction, Tongxin Machinery has brought together experienced engineers and industry experts to systematically innovate traditional centrales à béton, from structural design and intelligent control to full-process management, to launch a high-precision concrete mixing plant solution specifically designed for high-speed rail projects.
Solution 1: Intelligent Precision Weighing and Speed Control System - Overcoming Dynamic Precision Challenges
Aggregate Batching Innovation
We have innovatively introduced high-precision pneumatic control technology, equipping the batching bin door cylinders with high-sensitivity proximity switches to achieve intelligent coordinated operation of both doors. When unloading large quantities of material, both doors open simultaneously, ensuring efficient operation. When approaching the target weight, the system automatically closes one door, allowing the operator to precisely adjust the opening and closing angle of the other door based on real-time measurement data. This design completely eliminates metering errors caused by material inertia and mechanical response delays, maintaining dynamic batching accuracy within ±2%.
A Breakthrough in Powder Conveying
This system utilizes a unique twin-screw conveying system: the mother screw (main screw) is responsible for over 90% of the rapid conveying process, while the daughter screw (fine weighing screw) is responsible for precise feeding. An intelligent control system activates the twin screws during the bulk conveying phase and automatically switches to the daughter screw for fine feeding when the target value (90%-95%) is reached. This perfectly balances efficiency and accuracy, ensuring that powder metering errors are consistently maintained at ≤1%.
Liquid Metering Improvements
- Water Metering System: A dual-pump design for coarse and fine weighing is used in parallel. During the coarse weighing phase, high-flow, rapid water supply is provided; during the fine weighing phase, the system switches to a precise, small-diameter pipe for trickle water supply. The system intelligently predicts when to stop the pumps and utilizes the remaining water in the pipe for final metering, achieving milliliter-level control accuracy (within ±1%).
- Admixture System: To address the small dosage and high viscosity of admixtures, the system utilizes a specially designed, crystallization-resistant, corrosion-resistant precision conveying device, ensuring that even the smallest addition errors are strictly controlled within 1%.
Solution 2: Tongxin Cloud IoT Platform - Creating a Fully Transparent Digital Construction Site
Tongxin Machinery equips each high-speed rail mixing station with an intelligent control system based on the Industrial Internet architecture, seamlessly integrating it with the customer's management platform to create a comprehensive data hub.
Full-Process Data Visualization
Through a dedicated VPN and 5G network, a secure and stable data channel is established with the customer's monitoring center, allowing real-time upload of comprehensive production data, including batch records, consumption statistics, and alarm logs.
Intelligent Early Warning and Quality Intervention
When the system detects excessive batching deviations, insufficient mixing time, or abnormal raw material temperatures, it immediately activates a multi-level alarm mechanism: audible and visual alarms are issued at the local control center, real-time display is displayed on the customer's large monitoring screen, and alerts are sent to relevant personnel's mobile phones. If necessary, the system can automatically lock down the production process, establishing a comprehensive quality and safety assurance system.
Project-Level Precision Management
Production tasks can be created based on multiple dimensions, such as project, construction location, and strength grade. For example, the owner can remotely track data such as "128 cubic meters of C50 concrete poured today in Section 5, Pier 3, Section XX." All data is automatically generated into traceable reports, completely eliminating the possibility of cutting corners and falsifying data.
Option 3: Scientific Storage and Pretreatment System - Ensuring Stability from the Source
Expanding the Sand and Gravel Silo Cluster
The traditional four-silo layout has been upgraded to a large, independent silo with 12 independent silos. Based on the "first-in, first-out" principle and recycling, refined management is achieved: "Silo one for use, silo two for preparation, and silo three for storage." Each batch of incoming sand and gravel is ensured to undergo at least 72 hours of natural equilibration, minimizing moisture content fluctuations and laying a stable foundation for high-quality concrete production.
Professional Cement Storage and Temperature Control
We provide customized storage capacity planning based on the characteristics of cementitious materials. Eight large cement silos ensure that each material has sufficient residence time (≥3 days) for natural cooling, preventing high-temperature cement from entering the mill and ensuring that the incoming cementitious material temperature is consistently high.
