Drainage Ditch Liner
1. High construction efficiency: Compared to traditional concrete construction, it can save more than 50% of time and reduce labor and equipment investment.
2. Strong adaptability: It can adhere to irregular surfaces such as slopes, ditches, and outer walls of pipelines, solving the problem of traditional concrete being difficult to cover complex terrains.
3. Cost controllable: reduces the transportation and mixing costs of sand and cement, and has a low loss rate (high cutting utilization rate).
4. Safety improvement: No heavy machinery is required during the construction process, reducing the risk of on-site operations, especially suitable for narrow spaces or high-altitude operations.
Product Introduction:
Drainage Ditch Liner is a new type of composite material that combines cement with textile fibers. Its structure is usually based on high-strength textile blanket, uniformly impregnated with cement powder and additives inside, and covered with waterproof and breathable membrane on the outer layer. When in use, simply water the blanket, and the cement components inside will solidify upon contact with water, forming a hardened layer with certain strength and integrity, combining the flexibility of textiles with the structural properties of concrete.
characteristic
1. Combination of flexibility and hardening: Before watering, it can be curled, cut, and laid like a piece of cloth to adapt to complex terrain; After watering, it solidifies into a hard solid with strength close to traditional concrete.
2. Rapid construction: No need to mix or pour like traditional concrete, just water after laying, and the curing time is short (reaching the strength within a few hours to one day).
3. Lightweight and portable: The weight is much lower than that of concrete of the same volume, making transportation and handling convenient, especially suitable for remote or inconvenient areas.
4. impermeability and durability: After curing, a dense structure is formed with good impermeability, and the fiber substrate enhances crack resistance, resulting in a longer service life.
5. Environmental friendliness: There is no dust or noise pollution during the construction process, and the materials themselves do not contain harmful substances such as heavy metals, which meets environmental standards.
