Rejected concrete sleepers can be used as beams for foundation similar to grillage foundation to distribute load from column on wider area.
Dear Ishwar Sonar ,
It mainly depends on the damage and other reasons for rejection
suggestions for reuse
- boundary wall construction
-partition wall construction
-can be used as facing element in reinforced earth walls
-can be used to retain earth up to certain height. we can design.
-If sleeper was severely damaged then crush and make as aggregates.
- can be used as sheet pile
- may also be used as pile foundation for light structures depending on the structures primary function and subsurface condition.
all these in addition to you suggestion of as grillage foundation, beam
As Velusamy pointed out, severely damaged sleepers can be crushed and used as aggregates. If not that damaged they can be used as building blocks for walls, partitions etc. If damages are concentrated over a small area, .the remaining part can be cut to form blocks of regular shapes.. .in highly damaged cases, they can be used for soil stabilization by grinding to fine powder. They can also be used in levelling and filling up of areas as and when needed
Conversion sleepers into blocks is difficult due to pre-stressed cables available inside. Grinding sleepers into fine power looks costly solution. Thanks for participation.
Some applications suggested by Mr. Velusamy Gobinath are possible solutions where research can be conducted. Thanks
Mr. Velusamy Gobinath gave a very detailed answer to how to use a damaged sleepers.
In my opinion, it is more important to consider how to reduce sleeper damage during service (edequqte maintenance, special reinforcement for sleepers in sharp curves, etc.). Moreover, concrete sleepers should not be used where they could be subjected to impact and where there is an unstable substructure.
