Heavy-Duty Flood Control Sandbags with Drawstring Closure

Core Selling Points:

Superior Flood Control: L-shaped structure design utilizes water pressure for automatic reinforcement, achieving a 99.8% leak-proof rate, effectively blocking floodwaters up to 50cm height, protecting an area of 120 square meters per emergency operation.

Multi-scenario Adaptability: Angle adjustable by ±3°, perfectly adapting to various terrain elevations, can be quickly deployed in 15 common disaster scenarios including urban waterlogging, river overflow, and underground spaces.

Efficient Emergency Rescue: A single person can complete a 10-meter water barrier installation within 90 seconds without any tools, now standard equipment in 300+ flood control command centers nationwide.

Extreme Environment Adaptation: Rigorously tested to withstand extreme temperatures from -40°C to 95°C, maintaining 96% water-blocking performance under high-temperature drought or severe cold and frozen climate conditions.

Material and Craftsmanship Details:

Made of high-strength ABS engineering plastic with special surface UV-resistant coating treatment, uniform thickness of 5.2mm±5%, featuring an internal grid reinforcement structure design, controlling single piece weight at 3.8KG. The overall structure has passed impact resistance tests, capable of withstanding 30kg/cm² water pressure impact force, ensuring no deformation or displacement under extreme flood conditions, providing reliable flood protection.

Color/Style Display:

Red, with UV-resistant coating surface treatment and anti-aging design. The prominent red color is easy to identify and position at disaster sites, complying with international emergency rescue equipment standard color specifications, enhancing visibility during night and adverse weather conditions. The UV-resistant coating ensures no fading or embrittlement during long-term outdoor storage, extending service life to over 8 years. We can customize quantities and special markings according to the needs of flood control command centers, fire departments, and other institutions.

Usage Steps:

First confirm the installation location, place the bottom of the L-shaped water barrier on a flat surface with the red side facing the water source direction. Arrange and connect sequentially at designed intervals, locking adjacent panels through the built-in clip system to ensure seamless connection. For uneven ground, adjust angles by ±3° to adapt to the terrain. When encountering water, water pressure will automatically reinforce the L-shaped structure, requiring no personnel monitoring, with flood control effects lasting over 12 hours.

Application Scenarios:

Urban Waterlogging Protection: During rainy seasons, quick deployment in low-lying urban areas protects property of approximately 500 residents per 100 meters of water barrier. Applied in flood prevention systems of 20 major cities nationwide, reducing annual property losses by 28 million yuan.

River Overflow Emergency: During typhoon season, it's the first choice for riverside building protection, withstanding continuous water pressure for 12 hours per flood peak, protecting critical infrastructure. The 52×70cm size is particularly suitable for narrow river channels and quick deployment in rural areas.

Underground Space Protection: The 75×100cm size is specially designed for subway stations, underground parking garages, etc., each set blocking water level rise up to 30 centimeters. Equipped in subway systems of 40 cities nationwide, protecting underground space of 12,000 square meters daily.

Disaster Relief Supplies Protection: Build 80×100cm water barriers around temporary settlement points in disaster areas to keep relief supplies dry and safe, protecting supplies worth over 500,000 yuan per disaster relief operation.

Maintenance Guide:

Wash and dry after use, store away from direct sunlight. Conduct leak-proof testing at least once a year and check clip system integrity. Regularly apply specialized anti-aging agent to extend service life. For use in environments below -10°C, perform a 10-minute preheating treatment to maintain material toughness. Under normal use and maintenance, the product can be reused more than 50 times without significant performance degradation.
