Biodegradability Test for Bio Hori Drain® (KS M 3100-1)

 

Bio Hori Drain^® is biodegradable Prefabricated Horizontal Drain (Prefabricated Horizontal Drain) which can replace the natural aggregates for horizontal drainage for soft ground improvement work. 

Bio Hori Drain^® is eco-friendly product which can economically replace existing horizontal drainage system with its high discharge capacity (≥ 3,100cm3/s) 

Bio Prefabricated Horizontal Drain is composed of PBS(Poly Butylene Succinate) affiliated with aliphatic polyester and PLA(Poly Lactic Acid) extracted from cornstarch.

Description	Discharged pore water is drained by flowing into Bio PREFABRICATED HORIZONTAL DRAIN	Discharged pore water is drained by flowing into natural fiber mat	Discharged pore water is drained by flowing into plastic horizontal drains
Environ-mental Effciency	Excellent  (Degrades after settlement underground)	Normal  (Degrades underground)	Not good  (Stays underground after settlement)
Discharge Capacity	3,500cm3/s	Undetermined	400~1,200cm3/s
Characteristics	- Great efficiency of drainage  with open structure of water channels   - Highly economical   - Eco-friendly using biodegradable material   - Product made by DAEHAN	- Eco-friendly material using natural coir and jute   - Unstable quality as products are manually produced   - Significant reduction of water channel under surcharge	- Highly economical   - Significant reduction of water channel under surcharge   - Nod-degradable material
Recommendation	◎

 

Bio Prefabricated Horizontal Drain maintains its stable performance until the completion of the settlement. 
After 3 years from installation, it starts to biodegrade without leaving behind soil pollutant under the ground.

 

Comparison of long-term discharge capacity of Bio Prefabricated Horizontal Drain and other Plastic Horizontal Drains

According to the comparison of long-term discharge capacity of Bio PREFABRICATED HORIZONTAL DRAIN and other horizontal drains, discharge capacity of Bio Prefabricated Horizontal Drain is 2.5 ~ 8 times higher than other plastic horizontal drains.
