Construction of Pipe culvert by using TechFab Metal Gabions at Ghana
TechFab Metal Gabion
In October 2018, under government program of development of Ghana infrastructure, it was decided to build this Pipe culvert so that it will ease up to commute between two villages.
During monsoon, it was observed very high velocity flow in the river with 1m – 2m of water level in the River throughout the season and the access between two village was completely closed during this period, the Authority has earlier decided to construct the bridge which seems to be uneconomical at this location., Finally it was decided to construct the pipe culvert structure. The concrete pipe culvert again has some draw back during submerge condition so it was decided to construct flexible Gabion Pipe Structure in such condition.
The proposed solution here is with the RCC Pipes and Flexible Techfab Metal Gabions and Gabion Mattresses as apron.
The gabion structures become a flexible, permeable and monolithic structure and cost effective compare to the reinforced cement concrete structures. In this type hydraulic application and especially in transverse structure, the flexibility of structure play very important role., which can be constructed easily with very low foundation depth, if require can be constructed underwater up to certain depth, and gabion structure will take care of unequal settlement may occur.
So, Authority has decided to construct Gabion Pipe Culvert with flexible Gabion mattress as scour apron.
The Gabion pipe culvert is constructed successfully in September 2019 and the traffic has start moving.The Authority is very happy with the speed of construction and the working of structure as it is fulfilling the purpose for which it is constructed in well manner.
