Our water‑filled triangular flood tube is a portable, reusable flood‑defense solution made of heavy‑duty PVC coated tarpaulin. It forms stable triangular cross‑section after water filling; water weight provides anchoring force against flood impact. No heavy machinery required, 1‑person quick deployment. Fold compactly after draining for storage & transport. Ideal substitute for heavy sandbags for garage entrances, streets, river temporary interception, municipal emergency flood response. Support OEM, custom color & logo for global B2B buyers.

When water fills into the tube cavity, it forms rigid triangular cross‑section. The weight of internal water creates downward anchoring pressure. Higher flood water brings better stability to hold back incoming floodwater.
Our yellow water‑filled triangular flood barrier is built with robust modular construction for flood emergency defense. Every key component is carefully engineered for field‑use reliability.
Valve: Large‑caliber filling valve for fast water injection and drainage, convenient for quick deployment and post‑use emptying.
Glassfiber plate: Built‑in glassfiber plate supports triangular shape, maintaining stable geometric structure under high water pressure.
Reflective strip: High‑visibility reflective strip improves recognition at night, enhancing site safety during flood‑rescue operations.
Exhaust vent: Reliable exhaust vent for smooth air release during filling and deflating for compact storage.
PVC coated tarpaulin: Heavy‑duty waterproof PVC coated tarpaulin, tear‑resistant, anti‑aging, adapts to harsh outdoor environments.
After water filling, the barrier forms a stable triangular structure. Relying on water weight to generate friction against ground, it achieves self‑anchoring without extra fixings. Easy to roll up and store after cleaning and drying.

Unfold flood tube and lay flat on solid ground
Open air‑vent and water inlet valve, inject water until full
Close valves when deployment is completed
After use: drain all water, clean surface, dry thoroughly, roll for storage
Q1: How many workers for deploying this flood tube? （部署这个防洪管需要几个人？）
A: Only one person can finish unfolding and water-filling deployment quickly. （只需一人即可快速完成展开和注水部署。）
Q2: What ground conditions are suitable? （适用于什么地面条件？）
A: Flat hard ground like concrete, asphalt; also works for temporary river-bank interception. （适用于混凝土、沥青等平整硬质地面；也可用于临时河岸截流。）
Q3: Can it be reused after flood use? （洪水过后可以重复使用吗？）
A: Yes. Drain water completely, clean and air-dry before rolling for storage. （可以。将水完全排干，清洗并晾干后卷起存放即可。）
Q4: Can we make custom color and print our logo? （可以定制颜色和印制 Logo 吗？）
A: OEM & ODM supported, custom color, logo printing for bulk wholesale orders. （支持 OEM 和 ODM，大批量批发订单可定制颜色和 Logo 印制。）
Q5: What is the maximum water-holding height? （最大挡水高度是多少？）
A: Standard model for max 30cm water-blocking height, customized height is available. （标准型号最大挡水高度 30 厘米，也可定制更高。）
