10. a kind of construction method of the concrete filled steel tube sleeper of non-fragment orbit as claimed in claim 9, which is characterized in that packet
Include following steps:
Step 1: root long 2000mm, the hollow steel pipe of outer diameter 40mm are chosen；
Step 2: in position of the hollow steel pipe apart from open end 100mm-200mm, the extruding contracting in the length range of 0-50mm
As low as outer diameter 37mm forms several radial width diminutions portion (3)；And the intermediate stage of railway roadbed is embedded to, in 0- in hollow steel pipe
It is squeezed in the length range of 50mm and is contracted to outer diameter 37mm, form several radial width diminutions portion (3)；
Step 3: so as to form prefabricated several hollow steel pipes；
Step 4: being put into sleeper production mold for hollow steel pipe, steel reinforcement cage, sprays from one end of hollow steel pipe to the other end high
Press Concrete Filled material, until fill up the other end sleeper block die cavity and all radial width diminution portions (3), then proceed to
The sleeper block die cavity of this side is filled up, so that concrete filled steel tube (2) is poured into sleeper block (1)；
Step 5: maintenance concrete filled steel tube sleeper；
Step 6: concrete filled steel tube (2) interlude portion in the casting process of railway roadbed, including radial width diminution portion (3)
Divide to pour with railway roadbed and be integrated.
