As summer approaches, many schools are preparing for runway renovation projects. With 12 years of experience as a sports facility construction supervisor, I’ve observed that 80% of schools fall into these common traps during renovations: rushing construction without proper base preparation, using adulterated materials that cause odors, or failing to meet drainage slope standards leading to water pooling. Today, I’ll share hard-earned, million-dollar insights in this "foolproof" construction guide to help you dodge these pitfalls.
1. Pre-Construction Inspection: Don’t Skip the "Checkup"
Last year, a prestigious high school skipped base inspections to meet deadlines, only to see bubbles forming across their new runway within three months. Just like a building, a weak foundation spells disaster. Before breaking ground, ensure these tests are completed:
: Sebenzisa ithuluzi lokuphenduka ukuze uqinisekise ukuthi ikhonkrithi ihlangabezana nezinga le-C25 (amanani >25 MPa).
: Gaps under a 3-meter straightedge should not exceed 3mm.
: Film test results must be <5%.
Pro Tip: Filla iikhuzi nge-epoxy resin bese uhlanganisa izindawo ezingalingani (ukwehluka kokuphakama >5mm). Ungakholwa nokuqinisekiswa okuthi "i-layer encane ingafihla amaphutha"—lokhu kuyisithako sokuhlukana kamuva.
2. Izinto Zokukhetha Zinquma Ubude Bokuphila Kwe-Runway
Na mazhinji emhando dzisina kunaka dzichipinda mumusika, tarisa pamaitiro matatu aya:
: Khetha ama-particulate e-EPDM elastic (aqinisekiswe ngombiko we-ASTM D-412).
: Must comply with China’s updated GB 36246-2018 standard.
: Khetha i-glue engena-sovent (okuqukethwe kwe-TDI okukhululekile ≤0.5%).
Quick Quality Test: Rub particles—excessive color fading indicates poor quality. Smell adhesives—if pungent, reject them. Consider premium modified TPU (used in CBA league courts), which costs 15% more but extends lifespan by 3-5 years.
3. 7-Ikhono Lokwakha (Okubalulekile!)
Lezi zinyathelo ezithile zisetshenziswe ekwakhiweni kabusha kwesikhumbuzo somasipala:
: Hlanza izendlalelo ezindala ngomshini wokugaya (ubukhulu: 3-5mm).
: Sebenzisa i-primer yokungena yeziqu ezimbili (0.2kg/m²).
: Layi 8mm-thick cushioning (temperature >15°C).
: 3 cross-coated layers for even coverage.
: Sebenzisa uphiko lwe-polyurethane olungavumi i-UV.
: Umdla wamanzi kumele uqinisekise i-0.3%-0.8% ukwehla.
: Após 48 horas de fechamento, os níveis de TVOC ≤0,5mg/m³.
Critical Note: Apply elastic layers in two passes (4-hour intervals). Halt work if rain hits—humidity >75% causes layer separation.
4. Imininingwane Yokuhlola Ezinganakiwe
Izikole zivame ukugxila ezinhlelweni zokubukeka kodwa zishoda ngalezi zilinganiso ezifihlekile:
: Random core samples (allow ±1mm variance).
: Ijolalwe yokuphambuka kufanele ibe ngu-6-10mm.
: ≥0.7MPa (kuvimbira kupwanya).
DIY Test: Beka coin ku 30-degree incline—uma ikhuluma >50cm, i-anti-slip layer iyaphumelela.
5. Iingcebiso zokugcinwa ukuze wandise ubude bokuphila
A primary school’s 8-year-old runway still looks new thanks to:
- Ukucoca kwenyanga ngethuluzi lamanzi eliphezulu (pressure ≤100 bar).
- Quarterly checks for cracks at seams.
- Banning spiked shoes or heels.
- Ukulungiswa okuphuthumayo kokulimala ngeglue ekhethekile.
Winter Warning: Clear snow promptly—avoid metal shovels or deicing salts (use rubber scrapers instead).
Final Notes
Runway renovation isn’t just "laying plastic"—it’s an engineered system. Prioritize contractors with Grade II+ municipal qualifications and material traceability over low bids. For schools planning renovations, DM us to request our 18-Point Quality Control Checklist—it helps avoid 90% of common defects. Let’s build runways that keep students safe for decades!
