1. Installation and construction are convenient
Light in weight, small in size, low in transportation cost, and no need for large lifting equipment.
Simple requirements for the foundation, no need for complex concrete foundations, and the construction period is usually only 1/3 - 1/5 of that of traditional dams.
It can be modularly joined and the length of the dam body can be flexibly adjusted according to the width of the river channel.
2. Flexible operation adjustment
Quickly control the dam height by inflating and deflating air, with a short response time, and the dam can be raised or lowered within a few hours.
During the dry season, it can be inflated to hold back water to ensure irrigation, water supply or power generation; during the flood season, it can be deflated to tilt and not affect flood discharge, with high safety.
It can be dynamically adjusted according to water level changes and adapt to the water resource demands of different seasons.
3. Lower overall cost
The material cost and construction cost are only 1/4 - 1/2 of those of the same-scale concrete gravity dams.
There is no complex mechanical structure, and daily maintenance only requires checking air tightness and rubber aging conditions, with low maintenance costs.
The service life can reach 15 - 20 years, and the rubber material can be recycled, with obvious advantages in the total life cycle cost.
4. Strong environmental adaptability
The dam body is a flexible structure, which can adapt to the slight settlement or displacement of the foundation and is not easily damaged due to geological changes.
It does not block the migration of fish in the river channel, has a small impact on the ecological environment, and is especially suitable for ecologically sensitive areas.
It can be used in cold regions, and some products are equipped with anti-freezing devices to avoid damage from winter ice formation.
