[001] The present disclosure generally relates to the field of detachable insert pockets with shim provision. More particularly, the present disclosure relates to a detachable flexible insert pocket arrangements in a mould for manufacturing of a wider base sleeper.

BACKGROUND

[002] Usually the insert pocket has great significance to maintain gauge, alignment and toe load in a sleeper. Insert pockets are fixed in moulds before casting concrete and manufacturing of sleepers. Usually the insert pockets are cut at the bottom plates of mould which may be exclusively to one kind of sleeper design only. Care must be taken about proper positioning of insert pockets and restraints are provided in all directions but not achieved as required. Uncertainty of improper sitting of insert pockets inside mould can’t be eliminated completely due to shape of insert pocket, fixing arrangement in mould. Due to high frequency vibration during casting of sleeper inserts can dislocate, tilt, and get skewed, especially as the insert pockets get worn out.

[003] Conventional systems don’t cast the sleepers with different type of insert pockets. It is not possible as the insert pocket dimensions vary for different inserts. Conventional solutions fail to give flexible inserts pockets in a mould for casting the sleeper and also lack of locking arrangements to keep the insert in position while using a vibrator for compacting the concrete.

[004] In the light of aforementioned discussion there exists a need of systems with novel methodologies that would overcome or ameliorate the above mentioned disadvantages.
