The concrete bridge pier is being constructed using a tremie concrete placement method: using a pipe, concrete is placed underwater and its mass displaces the water around it. The lower end of the pipe is kept immersed in fresh concrete so that the rising concrete from the bottom displaces the water without washing out the cement content. A turbidity curtain surrounds the pier’s concrete forms to isolate the pour from the canal water, and the water within the curtain is treated if required.
Pouring the cap of the concrete bridge pier using the tremie placement method. The curve of the original pier has been maintained. Piles are visible in the centre of the pier that will support and transfer the load of the bridge to the rock below when installed.
An excavator lifts sheet pile into place. The sheet pile serves as a form for an upcoming concrete pour at the centre pier of the bridge.
Concrete is pumped into the form for the centre pier of the bridge.
Workers inside an enclosure guide the pouring of concrete for a bridge abutment. The enclosure is heated to ensure that the concrete cures properly, and the temperature is monitored.
