Project “ Accomplishment of Bank
Strenghtening Works for Reducing Risk of Destruction by Water of the Road of Interregional Importance “
Annex to the „Record of Proceeding“ on accomplished works of the Project
• The Project has been of a very good imput for the future development of mountain valleys, their population, security of the trafic and possibility of stable and secure access of the local inhabitants to district centers and to stable food supplies.
• The Project objectives: in tune with national and international strategy of regional development as well as with general goals of Czech cooperation programme.
• The Project results: streghtening the Jagnob river bank and improvemnts of the trafic, minimization of risk of the road and other constructions innundation.
On the spot, where the road was covered (blocked) by the fragmental material of landslide flow, the road was detached from the sediments and enlarged enough to enable at leased two cars (trucks) to pass at once. The overall length of this road part - 34 meters
The road after the ladslide took place in 2007
The road after its recuperation
The river-basin of the Jagnob confluent which was blocked as the result of the landslide has been thanks to the earth works recuperated and the water was directed to the old river-basin. The concrete tubes under the road were made free from the fragmental material
The dam in the river made by the landslide material was removed and the river-basin – its right-side part of 65 м length was deepened up to 1,5 – 2 meters so that the water could pass without obstacles and does not accumulate behind the dam (as it was after the landslide in 2007)
The river margin has been strengthened on the length of 52 m
On 350 m upstreem the road was innundated by water which was running in by an aside branch. This inflow place was blocked by a wall made from gravel and ballast on 65 m. The road was stregthened in these 350 m
Concrete tube laying job by the local inhabitants
The escavators were used on the length of 2 km on which the main works were conducted. The streem-basin in these places was deepened and concrete tubes laid under the road so that its water could easily reach the Jagnoba river
The evident need in the river-basin changes
The most effective solution was to deepen the left-side of the river-basin. As the river-basin was deflected from the road its right bank will be not more destroyed by the erosion. For these operations the heavy machines had to be transported over the river-basin onto the other river bank
