MARCH AND APRIL 2010 |
|
|
 |
Installation of new reinforcing members in sector B2 above St-Laurence River. |
|
|
|
 |
New post tension steel bars are added under the Ramp 3, direction Chateauguay. |
|
|
|
 |
Those bars are tensioned with powerful hydraulic jacks. |
|
|
|
 |
The bars are anchored to the structure so that it can take the load of the new deck. |
|
|
|
 |

|
|
 |
In B2 sector, above St-Laurent’s river direction south shore, new members are installed to accommodate the loads of the new decks. |
|
|
|
 |
Steel plates are also required on diagonals, this photo show the amount of work to bolt those plates to the actual structure. |
|
|
|
 |
Steps to install those plates are: cleaning of existing steel, adjusting the plates, drilling holes in the existing steel structure and bolting.
|
|
|
|
 |
In Ramp 3, from Montreal to Chateauguay, steel structure is enlarged to accommodate the new bike path. |

|
|
|
 |
This ramp’s configuration requires special work platform installation. |
|
|
|
 |
These works require some lane closures on ramp 2. |
|
|
|
 |
A clearance marker has been erected to control the truck height. |
|
|

FEBRUARY
2009 |
|
|
|
Platforms have been installed under the steel structure of Ramp 4. |
|
|
 |
Under the ramps, platforms are installed with boom trucks. |
|
|
 |
Platforms are installed over the entire length of Ramp 4. |
|
|
 |
Platforms, larger than the bridge, offer a roomy and safe work zone. |
|
|
|
Repairs and reinforcing steel works have started on the steel structure of Ramp 4.
These works will be carried out in the following stages: |
|
|
 |
Rivets removal. |
|
|
 |

|
|
 |
Preparing surfaces, by removal of paint and rust. |
|
|
 |
Installation of the new plates. |
|
|
|
JANUARY
2009 |
|
|
|

|
MAY TO DECEMBER 2008 |
|
|
|
Platforms were being
installed in Sector B1 and on about half of Sector B2.
Steel works in sector B1. |
| |
|
 |
In Sector B1, platforms are being installed with skylifts. |
| |
|
 |
For Sector B2, platforms were assembled on the shore. |
| |
|
 |
Platforms were then transported by boat and lifted under the structure. |
| |
|
 |
In Sector B2, scaffoldings were erected on each side of the structure to perform work on the trusses. |
| |
|
 |
Reinforcing gusset plates, by adding new steel plates, is the major work in this area. Lattice bars join in nodes where gusset plates connect them. |
| |
|
 |
The first operation on the nodes is to remove the rivets and to replace them by bolts. |
| |
|
 |
Reinforcing plates are fabricated in the shop. |
| |
|
 |
New reinforcing plates are ready to be installed. |
| |
|
 |
New plates are added one by one in a predefined order.
