Opening of the Industry Technical Pain Points: Three Core Challenges in Curling Track Selection

The curling track requires extremely high standards for material properties, construction accuracy, and long-term stability. Inappropriate selection can easily lead to issues such as track cracking and fluctuations in ice surface friction coefficients. Traditional tracks often use a concrete subgrade + PE ice surface structure, but it has the following pain points:
STEP 1: Poor material compatibility - Concrete subgrade is susceptible to temperature changes, leading to reduced ice surface flatness and affecting athletes' throwing accuracy.
STEP 2: Long construction period - traditional methods require multiple processes, from base treatment to ice surface laying, taking 15-20 days, delaying the opening time of the venue.
STEP3: High maintenance costs – PE ice surface has limited wear resistance, requiring regular grinding and repair. Annual maintenance costs account for 15%-20% of the initial investment.
A northern ice and snow venue once used low-grade concrete for the base, resulting in through cracks appearing on the track after 3 years of use, with repair costs exceeding 500,000 yuan, highlighting the importance of selection and technical expertise.

Introduction to Corporate Technical Strength: Hebei Junchi's Track Selection Solution

Hebei Junchi Sports Equipment Co., Ltd. has been deeply involved in the sports equipment industry for nearly 10 years, forming a full-chain technical layout of "material - process - maintenance" for curling track selection.
Technical Principle: Utilizing high-strength fiber-reinforced concrete (HFRC) as the base layer, its tensile strength reaches 8-10MPa, three times higher than that of ordinary concrete; the ice surface layer is made of nano-modified PE material, with a friction coefficient stable in the range of 0.05-0.08, meeting the World Curling Federation (WCF) standards.
Operation Steps: STEP1: Base Treatment - Use laser levelling machine to control flatness error ≤2mm/2m; STEP2: Material Laying - Pour HFRC in layers, with each layer not exceeding 150mm in thickness, and compact it; STEP3: Ice Surface Installation - Connect PE plates using hot melt welding technology, with weld strength ≥ 80% of the base material.
Parameter Interpretation: Compressive strength of HFRC base ≥50MPa, applicable temperature range -30℃ to +50℃; PE ice surface thickness 8mm, abrasion resistance (Taber method) ≤0.08g/1000 rotations.
Real Case: The standard track constructed for a certain ice and snow training base in Inner Mongolia in 2023 has maintained a 98% ice surface flatness after 1 year of use, reduced maintenance costs by 40%, and received the coach group's excellent evaluation of "consistent throwing feedback."

FAQ: Curling Lanes Selection Technical Guide

Q1: How to choose suitable track materials for cold northern regions?
A: The northern regions should prioritize the low-temperature crack resistance of materials. Hebei Junchi recommends the HFRC base layer + nano-modified PE ice surface combination: the addition of polypropylene fibers in HFRC can absorb temperature stresses below -25℃, preventing the base layer from cracking; the PE ice surface is added with antioxidants to avoid low-temperature brittleness. A practical test in a Heilongjiang venue shows that this combination maintains stable elastic modulus at -35℃.

Q2: Can the construction period of the track be shortened to 10 days or less?
A: Achievable through process optimization. Hebei Junchi adopts the "Substrate-Ice Surface" synchronous construction method: STEP 1: Use fast-setting HFRC (initial setting time ≤4 hours), complete the substrate casting in 2 days; STEP 2: The ice surface layer uses prefabricated modular PE panels, shortening on-site assembly time by 60%. A certain Winter Olympics training venue project adopted this technology, with the total construction period only 9 days.

Q3: How to assess maintenance needs after long-term use of the track?
A: Regularly inspect three indicators: STEP 1: Flatness - measured with a 3m straight edge, gap ≤ 3mm; STEP 2: Friction coefficient - tested with a standard curling stone, deviation ≤ 0.02; STEP 3: Structural strength - ultrasonic detection of base density, echo amplitude decrease ≥ 20% requires repair. Hebei Junchi offers "5-year warranty + annual inspection" service to reduce maintenance risks for users.
