Product Description

Advantage:
1. No power or human labor required, fully driven by water itself
2. Lightweight structure for manual operation;
3. Can be constructed in either ramp form sitting directly or ground or embedded form flush to ground.

Product Specification:

Flood Height:
H0.6-H1.5meter to be customized as per request;
Length:
Fits the doorway width between side walls (Supply in module);
Orer-Pass Weight:
Allow vehicle within 4.5 Metric Tons (higher strength can be customized if required).

Requirement:
1. Side Wall (to attach the end retaining rubber);
2. Flat ground plastering ±3mm;
3. Require ground slotting work for containing space if flush to ground is required.
4. Drainage inside the box can be considered to be pre-constructed before start the installation or prepare a small pump to drain the water inside after flood.

NEWFLAG Automatic Flood Barrier which is hydrodynamic driven by rising flood water itself, can be customized in module supply form according to the doorway width at site. It consists of the bottom frame,floating barrier panel with non-slip surface in module supply, and the end sealing rubber attached to the side wall.The rising or retreating flood water will flip up or close down the barrier panel automatically and it does not require power or human to intervene.It can be also manual lifted by an adult due to its lightweight technology. The structure is designed simple to reduce the risk of failure and easy to repair or replace.

Installation Technical Requirements: the overall installation accuracy is ±5mm, ground flatness requirements ≤3mm/m. According to the requirements of site, it can be constructed in 1. Ramp form directly sitting on existing ground with speed bump attaching both sides (Product height when closed is approx.55-60mm above the ground); 2. Embedded form with top surface flush to ground by slotting the ground for containing space.
The weight of the lightweight barrier panel with great strength is about 18.5KGs/Square Meter which can withstand the crush of vehicle weights 4.2 metric tons. We can customize the barrier panel for the requirement even for container truck.

*Alarming system is optional if required.

Water buoyancy barrier structure

SUS304 stainless steel bottom frame, stainless steel wire rope, buoyancy baffle, EPDM flexible seal, SUS304 anti slip panel, etc.

The product adopts modular assembly technology, which can achieve rapid on-site installation. The working principle of this device is that the overall buoyancy of the baffle is less than that of water. The device is fixed on the ground, and when the area of water exceeds the height of the baffle, the buoyancy of the water pushes the baffle upward to rotate. When the accumulated water drops, the baffle synchronously drops with the water level, ultimately achieving automatic flood prevention and water blocking.

The overall barrier can be installed by ground embedding or surface installation, and the embedded installation barrier device is flush with the ground to achieve barrier free passage. If installed on the ground, the barrier device will be about 5 centimeters above the ground and can be used as a speed bump for vehicles entering and exiting.

During non flood season, there is no standing water on the ground, and the barrier is in close contact with the bottom frame, allowing pedestrians and vehicles to freely pass through.When there is water accumulation on the ground during the flood season, the accumulated water flows into the bottom cavity through the bottom frame inlet grille, and the buoyancy of the water is used to push up the baffle to achieve water blocking function.
