Agent guarantees to fit closely between construction period concrete sleeper block 1 and elastomeric isolation gumshoe 7；7 peripheral edge of elastomeric isolation gumshoe
All using the rubber belt sealing of width 10cm or more between concrete sleeper block 1, guarantee entire work progress must not make sundries into
Enter in elastomeric isolation gumshoe 7.
The sleeper foundation pit size that railway roadbed digs construction is no less than 795 × 368 × 210mm (length × width × height), sleeper base
The cement film, loosening stone or the weak concrete layer of pine for cheating inner surface answer thorough cleaning clean, expose clean, fine and close new stubble,
It can just be further processed.
After first skylight point time completion sleeper foundation pit is cut, sleeper supporting rail 9 should be installed in foundation pit, guaranteed
Next day normal operation.Sleeper laying is completed within second skylight point time pours work, and the shape since second skylight point
At streamlined operation.Railway roadbed, which is cut, to dig a mode using every six, i.e., cut a former sleeper every six sleepers, more by batch
It changes, cut, until having replaced all sleepers.
Before replacing elastic sleeper, chooses side single steel rail 9 and remove 9 attachment fastener 8 of rail, dismounting range is the rail
Each 50m in pillow front and back.To unclamp rail attachment fastener 8 rail 9 raise track after, assembling can be spelled and tear elastic sleeper open and be placed into cutting
In sleeper foundation pit.This root rail 9 is dropped back into original position again, installation, which can spell, tears elastic sleeper split rail attachment fastener 8 open and restore
The rail attachment fastener 8 of remaining position is answered before construction using the other side this 9 height above rail surface of root rail of intact 9 accurate adjustment of rail
It is unified that rail cant adjustment is carried out to section to be replaced, rail cant is controlled 1/30~1/50.
Two standalone elastic sleepers friction type high strength bolt 4 and connecting plate 5 securely connect, and wing plate connecting plate uses single side
Board size is 360 × 160 × 10mm (length × width x thickness), and web connecting plate is (long having a size of 240 × 60 × 10mm using dual platen
× width x thickness).
After the completion of elastic sleeper accurate adjustment, ditch template is installed between the pairs of concrete sleeper block 1 and foundation pit,
High-performance self-compacting mortar is perfused into the gap between the foundation pit and elastomeric isolation gumshoe 7, removes ditch after mortar initial set
Template；Ying Shuichong before mortar, infiltration are poured, but must not have ponding, reaches the wet interior dry state in face, and in foundation pit after the cleaning
Wall sprays conjunction old and new concret glue.
