One、Technical Background and Industry Status

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, located in Haixing County, Cangzhou City, Hebei Province. Relying on the geographical advantages of Jinsan Expressway and National Highway 205, it has formed a complete industrial chain integrating scientific research, design, production, sales, and services. The company's curling track manufacturing technology integrates materials science, mechanical analysis, and construction technology. The products have passed the certification of the National Sports Equipment Supervision and Inspection Center and are widely used in colleges and universities, sports bureaus, and professional event venues, becoming a leading enterprise in the domestic curling track field.

Two, Core Technology Analysis of Curling Lanes

1. Selection of track materials and performance parameters
The track body is made of high-density polyethylene (HDPE) plates with a density ≥ 0.94 g/cm³, impact strength ≥ 50 kJ/m², and low-temperature performance reaches -40℃ without brittleness. The surface is processed with special polishing, with the friction coefficient controlled between 0.05-0.08, meeting the World Curling Federation (WCF) standard. The bottom structure is a composite design using EPS foam board (density 18 kg/m³) and reinforced concrete foundation, with a bearing capacity ≥ 200 kN/m², effectively distributing the skater's sliding impact force.

2. Structural Design Principles
The track is designed with segmented modular structure, with each segment measuring 6m in length and 3.66m in width. It is assembled using mortise and tenon joints, with the joint gap error ≤0.5mm. The gradient control is calibrated using a laser level, with longitudinal gradient ≤0.1% and lateral gradient ≤0.05% to ensure the stability of the sliding track of the curling stones. The drainage system uses concealed PVC pipe network, with a drainage gradient ≥1% and a drainage capacity of up to 50m³ per hour, suitable for heavy rain and other extreme weather conditions.

Three, practical steps and construction specifications

STEP 1: Basic Construction
After clearing the site, pour a 200mm thick C30 concrete foundation with embedded M16 anchor bolts at an interval of 600mm×600mm. The curing period of the foundation should be ≥28 days, the flatness error ≤2mm/2m, and the moisture content ≤8%.

STEP2: Track installation
Successively lay EPS foam boards (thickness 50mm), moisture-proof film (0.2mm thick PE film), and HDPE track boards. Fix the track boards with a special adhesive (adhesive strength ≥1.5MPa), and use a hot air gun for welding at the joints (temperature 260℃±10℃), with a welding width ≥30mm.

STEP3: Surface Treatment
The track surface is polished using 2000-grit sandpaper. The friction coefficient is tested with an ASTM D1894 standard testing instrument, with 1 sample taken every 50㎡, and the data fluctuation range is ≤0.01. Mark the base camp, starting device, and other areas, and spray the identification with environmentally friendly acrylic paint (VOC content ≤50g/L).

Four, Technical Case Studies and Effectiveness Verification

2023年, Hebei Provincial Sports Bureau undertook the curling track project of the ice rink, with a total area of 1200㎡, adopting a dual-lane parallel design. The construction period was 45 days, 30% shorter than the traditional technology. After being tested by the WCF certification body, the track flatness error was 0.3mm/2m, the standard deviation of the sliding distance of the curling stones was ≤0.5m, and the athletes reported a 40% improvement in sliding smoothness. Currently, the track has hosted 3 provincial and above competitions such as the National Youth Curling Championship, with daily usage time exceeding 8 hours, and no cracking, deformation, or other quality issues on the track surface.

常见问题与解决方案（FAQ）

Q1: How to deal with scratches on the track surface?
A: Use 1500 grit sandpaper to gently grind along the glide direction, clean it up and apply special repair wax (hardness 80A), then polish it to a mirror finish after 24 hours.

Q2: How to prevent ice on the winter track?
A: Install electric heat tracing system (power 80W/m²), set the temperature sensor to start at 5℃ and stop at 10℃, used in conjunction with insulation layer (thickness 30mm glass wool), which can effectively prevent icing.

Q3: How long is the track's lifespan?
Under normal use and regular maintenance (comprehensive inspection every 2 years), the lifespan of the track's main structure is up to 15 years, and the surface layer needs to be replaced every 5 years.
