Abstract
A kind of tunnel immersed tube joint Horizontal concrete shear key preparation method, when sleeper beam is prefabricated, axis reinforcing bar and connector are buried between steel seals up a door locking stake, vertical reinforcement and connector are buried in front end；After the completion of leading portion immersed tube docks with back segment immersed tube, remove steel closure door, adjust leading portion immersed tube, the axis reinforcing bar on back segment immersed tube sleeper beam and connector and vertical reinforcement and connector, make the axis reinforcing bar on leading portion immersed tube sleeper beam and the axis reinforcing bar cross-shear on back segment immersed tube sleeper beam, vertical reinforcement intersects with axis reinforcing bar simultaneously, and reinforcing bar colligation is carried out to axis reinforcing bar and vertical reinforcement staggeredly, after-pouring concrete.The tunnel immersed tube joint Horizontal concrete shear key preparation method of the present invention, by burying sleeper beam axis reinforcing bar and connector and vertical reinforcement and connector during prefabricated sleeper beam, plugged into full group of shearing bond structure vertical reinforcement by reinforcing bar after chisel sleeper beam in a small amount of repair, the purpose using existed concrete bridge structures is finally reached, has reached economic and environment-friendly effect.
Description
Technical field
The present invention relates to tunnel immersed tube joint technique, especially a kind of tunnel immersed tube joint Horizontal concrete shear key makes
Method.
Background technology
Tunnel immersed tube joint connection is mainly cut by axis PC drag-lines, vertical Steel shear key and transverse horizontal armored concrete
Cut key.Reinforcement construction concrete shearing key of the prior art, it is to cut sleeper beam after tube coupling sinking docks dismounting closure door to own
Concrete, retains its vertical cage bar, is used as shear key main body vertical reinforcement after calibrated, then colligation residue reinforcing bar, pours coagulation
Soil forms.Difficulty is dug out and there is concrete in this technical scheme（Immersed tube concrete strength is high）, reinforcing bar is not easy to protect（Former pillow need to be retained
Beam vertical reinforcement）Etc. problems.
The content of the invention
Existed concrete bridge need not be cut it is an object of the invention to provide one kind or reduces the amount of cutting, and can realize that sleeper beam mixes
The recycling of soil is coagulated, to reduce the tunnel immersed tube joint Horizontal concrete shear key preparation method of production cost.
The tunnel immersed tube joint Horizontal concrete shear key preparation method of the present invention, it is characterised in that when sleeper beam is prefabricated,
Axis reinforcing bar and connector are buried between existing equally distributed steel closure door locking stake, vertical steel is buried in steel closure door locking stake front end
Muscle and connector；After the completion of leading portion immersed tube docks with back segment immersed tube, steel closure door, regulation leading portion immersed tube, back segment immersed tube sleeper beam are removed
On axis reinforcing bar and connector and vertical reinforcement and connector, the axis reinforcing bar on leading portion immersed tube sleeper beam is rested the head on back segment immersed tube
Axis reinforcing bar cross-shear on beam, while vertical reinforcement intersects with axis reinforcing bar, and to axis reinforcing bar and vertical steel staggeredly
Muscle carry out reinforcing bar colligation, after-pouring concrete, formed immersed tube joint Horizontal concrete shear key.
The tunnel immersed tube joint Horizontal concrete shear key preparation method of the present invention, by burying sleeper beam during prefabricated sleeper beam
Axis reinforcing bar and connector and vertical reinforcement and connector, plugged into full composition shearing bond by reinforcing bar after chisel sleeper beam in a small amount of repair
Structure vertical reinforcement, the purpose using existed concrete bridge structures is finally reached, realizes the utilization to existed concrete bridge structures,
The effect of economic environmental protection is reached.
