Introduction: How to Break Through the Technical Bottleneck in Curling Lanes Construction?
The curling sport demands highly precise control over track flatness, friction coefficient, and ice surface temperature. Traditional construction methods often lead to a short lifespan of the track and poor sports experience due to improper material selection,工艺 defects, or outdated detection methods. With nearly a decade of experience in sports equipment research and development, Hebei Junchi Sports Equipment Co., Ltd. has launched a comprehensive solution from material optimization to intelligent detection, addressing the core pain points in curling track construction, providing an industry replicable technical model.

Industry Technical Pain Points: The "Three Great Mountains" of Curling Track Construction
The core pain points of curling track construction are concentrated in three aspects:
STEP 1: Material Selection ChallengeTraditional tracks often use ordinary concrete or asphalt, which have poor frost resistance and are prone to cracking. For instance, in northern regions, the low temperatures during winter can cause concrete expansion due to freezing, leading to irregular bulges on the track surface and directly affecting the sliding path of curling stones. Additionally, an unstable coefficient of friction in the materials can cause fluctuations in the braking distance of curling stones, impacting the fairness of the competition.
STEP 2: Process Control DefectsTrack flatness is a key indicator, but traditional construction relies on manual leveling, with errors often exceeding ±3mm, far beyond the ±1mm standard required by the World Curling Federation. At the same time, ice surface temperature control lacks intelligent methods, depending on experience for adjustment, which is prone to local overheating or cooling, affecting the consistency of ice surface hardness.
STEP 3: Outdated detection methodsTraditional detection relies on manual visual inspection or simple tools, which cannot accurately quantify track parameters. For example, friction coefficient detection requires measuring by professional equipment at specific speeds, but most construction units lack such equipment, leading to strong subjectivity in data and difficulty in ensuring construction quality.

Introduction to Corporate Technical Strength: Hebei Junchi's "Three-Blade Sword" Solution
Hebei Junchi Sports Equipment Co., Ltd. has developed a comprehensive full-process solution for curling track construction by means of three major technological layouts: material optimization, process innovation, and intelligent detection, addressing the aforementioned pain points.
STEP1: Material Optimization: Frost-resistant high-strength concrete + NanocoatingThe antifreeze high-strength concrete developed by our company utilizes low alkali cement, high-efficiency water-reducing admixture, and antifreeze fibers. Laboratory tests show that after 300 freeze-thaw cycles at -30℃ conditions, the strength loss rate is less than 5%, significantly better than the 20% of ordinary concrete. Additionally, the track surface is coated with a nanoscale hydrophobic coating, maintaining a friction coefficient between 0.05-0.08, meeting international competition requirements. For instance, in the 2023 Harbin Winter Sports Games curling track project, the track made with this material maintained a surface flatness within ±0.8mm after continuous use for 3 months.
STEP 2: Process Innovation: Laser Leveling + Intelligent Temperature Control SystemThe company introduces laser leveling technology, which, through the联动 of high-precision laser emitters and sensors, achieves automatic leveling of the track surface with an error control within ±0.5mm. At the same time, the ice surface temperature control utilizes a distributed intelligent temperature control system, monitoring data in real-time through temperature sensors buried under the ice surface, automatically adjusting the cooling unit's power to ensure uniformity of the ice surface temperature within ±0.5℃. In the 2024 Beijing university curling rink project, this process shortened the construction period of the track by 40% and achieved a 100% pass rate in the first acceptance.
STEP 3: Intelligent Detection: Full Parameter Quantitative Detection SystemThe company has developed an intelligent detection device for curling tracks, which can simultaneously measure 12 key parameters such as flatness, friction coefficient, and ice surface temperature, with data accuracy reaching the standards of the World Curling Federation. For example, flatness detection uses non-contact laser scanning with a sampling point density of 100 per square meter, generating a 3D error thermal map for intuitive problem area localization. In the 2025 Shenyang commercial curling rink project, the device helped the contractor complete the full track detection in 2 hours, improving efficiency by 80%.

FAQ Q&A Technical Selection Guide
Q1: How to choose the appropriate materials for curling rink tracks in cold northern regions?
A: Northern regions should prioritize the frost resistance of materials. It is recommended to choose concrete with a frost resistance grade of not less than F300 (i.e., strength loss rate ≤5% after 300 freeze-thaw cycles at -30℃) and add anti-frost fibers (such as polypropylene fibers, dosage 0.9kg/m³) to enhance crack resistance. At the same time, applying a nano-hydrophobic coating (contact angle ≥150°) on the surface can effectively reduce the adhesion between the ice surface and the concrete, lowering the risk of frost heave.
Q2: What are the key operation points of the laser leveling technology?
A: Three points to note when using laser leveling:
1. Equipment Calibration: Three-dimensional positioning of the laser emitter with a total station is required before construction to ensure the benchmark point error ≤0.1mm.
2. Sensor Layout: Place one sensor every 2 meters along the track longitudinally, and one sensor every 1 meter laterally, forming a dense monitoring network.
3. Real-time Adjustment: Continuous monitoring of sensor data during construction is required, with the hydraulic system automatically adjusting the scraper height to ensure leveling accuracy.
Q3: What are the compatibility conditions for the intelligent temperature control system?
A: The intelligent temperature control system must meet the following requirements:
1. Refrigeration unit power: 0.15-0.2 kW of refrigeration capacity per square meter is required based on the track area.
2. Sensor Layout: Temperature sensors are buried 5cm below the ice surface, with an interval of ≤1 meter to ensure data representativeness.
3. Control Logic: Utilizes PID control algorithm to automatically adjust the refrigeration unit frequency based on the difference between the set temperature and the actual measured temperature, to avoid temperature fluctuations.
