1. Enterprise technical strength and curling track layout

Hebei Junchi Sports Equipment Co., Ltd. is located in Haixing County, Cangzhou City, Hebei Province. As a large-scale professional enterprise integrating scientific research, design, production, sales, and service, the company has been deeply involved in the sports equipment industry for nearly 10 years. Adhering to the philosophy of "Quality is life, credibility wins the market," the company's products cover outdoor fitness equipment, basketball hoops, table tennis tables, and have been continuously recognized as qualified products by the National Sports Goods Supervision and Inspection Center. In the curling track field, the company relies on independently developed ice surface materials and structural technology, combined with international standards, to form a complete track construction solution, widely applied in colleges and universities, sports bureaus, and professional competition venues.

II. Curling Track Technical Analysis: Materials and Structure

The core technology of curling rink lies in the ice surface material and the base structure. Hebei Junchi uses high-density polyethylene (HDPE) as the bottom material for the ice surface, with a density of 0.94-0.96g/cm³ and impact strength of up to 20kJ/m², which can effectively resist friction and impact during the sliding of curling stones. The base structure of the track is divided into three layers: the bottom layer is 10cm thick C25 concrete, the middle layer is a 5cm thick rubber shock-absorbing pad, and the surface layer is a 2cm thick HDPE ice surface. This design ensures that the track flatness error is ≤2mm, and the ice surface friction coefficient remains stable between 0.05-0.08, meeting the standards of the World Curling Federation (WCF).

3. Construction Process and Key Parameters

STEP1: Site Preparation. Clean the base, ensure no debris, concrete subgrade compressive strength ≥25MPa, flatness error ≤5mm. STEP2: Rubber Pad Laying. Use special adhesive to stick, overlap seams by 2cm, use a roller to compact, ensure no bubbles. STEP3: HDPE Ice Surface Installation. Use a hot air gun to heat the edges of the boards to 120°C to melt and bond the seams, then cool to form a seamless ice surface. STEP4: Ice Surface Polishing. Use a professional ice grinder to grind the surface roughness to Ra≤0.8μm, ensuring smooth sliding of curling stones. STEP5: Temperature Control.埋设 ground heating pipes under the track, maintain the ice surface temperature between -5°C to -3°C through a temperature control system, to avoid cracking or deformation of the ice surface.

Chapter 4: Case of Enterprise Technology Application: Construction of a Curling Center in a Certain University

In 2022, Hebei Junchi built a standard curling rink for a university with a track size of 45.72m×5m, adopting the aforementioned technical solution. The construction period was 45 days, and the flatness error at acceptance was only 1.2mm, with an ice surface friction coefficient of 0.06, fully meeting WCF standards. After the venue was put into use, it hosted a provincial curling championship, and athletes reported high stability during sliding and strong durability of the track, with no issues of ice cracking or deformation to date. This case validates the applicability and reliability of the company's technology in professional sports venues.

5. Frequently Asked Questions (FAQ)

Q1: How to handle the cracking of curling track ice?
A: Cracks are usually caused by temperature fluctuations or foundation settlement. Solutions include: 1) Inspect the underfloor heating system to ensure stable temperature; 2) Local heating repair for the cracked area, resurface the ice; 3) Enhance the strength of the foundation concrete to prevent settlement.
Q2: How to extend the track service life?
A: Regular maintenance is crucial. It is recommended to conduct a comprehensive inspection at the end of each season, including the ice surface flatness, rubber pad elasticity, and ground heating system efficiency. Replace the rubber pads every 3 years and resurface the HDPE ice surface every 5 years to ensure the track's long-term stable operation.
Q3: How is the cost of curling track construction controlled?
A: Cost is affected by materials, construction techniques, and site conditions. Hebei Junchi can reduce the construction cost of a single track by 15%-20% through optimizing material ratios (such as using domestic high-density polyethylene instead of imported materials), standardized construction processes, and mass production, while ensuring the quality meets international standards.
