One 191 and the joint face of tube coupling 2 192 are saved, the end face of pushing tow girder 22 is provided with waterstop 23, and waterstop 23 is small perpendicular to pushing tow
The end face of beam 22, the material of the girder front end waterstop 23 is natural rubber, and the end chamfer of girder is fixed on by casting die system
On, waterstop and casting die system are each perpendicular to girder end chamfer.Waterstop encloses along girder end chamfer arrangement one, jack 21
Piston rod on connect pushing tow girder 22, the pushing tow girder 22 is connected to the tube coupling 1 by girder sliding block 24
On the joint face of tube coupling 2 192, waterstop 23 contacts in the presence of pushing tow girder 22 with having installed the adjacent surface of tube coupling 25,
Waterstop 23 realizes binding cavity and extraneous sealing after being sufficiently compressed, the binding cavity draining after being easy to, form dry apply
Work environment.
Before sinking FS final spice, remaining immersed tube tube coupling has installed, and forms the breach for installing FS final spice,
Because seabed has the environmental conditions such as complicated ocean current, other mounted tube couplings intercept greatly equivalent to having built one in seabed
Dam, larger water body flow in indentation, there be present, it is difficult to ensure that zero deflection is docked between FS final spice 19 and adjacent tube coupling 25, cause
Make to deviate between the end face of adjacent tube coupling and waterstop 23.Therefore, how to ensure that waterstop 23 splices with adjacent tube coupling 25,
After FS final spice 19 is installed with adjacent tube coupling 25, the end face that waterstop 23 is smoothly fitted in adjacent tube coupling 25 seals so as to realize
Sealing, turn into the key factor for completing FS final spice installation.
In order to ensure the water-stagnating effect of waterstop, in the end set steel cap of the adjacent tube coupling spliced with FS final spice.Steel
Cap needs to provide a flatness and the minimum end face of construction error, smoothly to realize that waterstop extrudes, realizes FS final spice steel
Load smooth-going is transmitted between shell concrete and adjacent tube coupling reinforced concrete structure, and steel cap needs to bear to produce during pushing tow girder pushing tow
Raw load, and the deflection occurred under pushing tow load does not interfere with the hermetic seal of waterstop, therefore, the knot of steel cap
Structure realizes that hermetic seal plays an important roll to waterstop.
