Estimating the term…
Systems and methods are described for forming a concrete trench drain channel using a slipform paving machine. The drain channel has frames that define an upper opening that can receive a grate. The slipform methods provide the slipform paving machine with moulds shaped to represent the external and internal profiles of the drain channel. One or more frames are installed in an abutting manner on a trestle that extends from the slipform paving machine so the frames are located at the upper opening of the inner profile of the drain channel in the internal mould. The slipform paving machine is actuated to continuously slipform the channel in concrete in between the exterior and interior moulds and around the frames. This process is repeated until the frames are at least partially embedded in the concrete and located across the opening of the drain channel.
A method for slipforming a concrete trench drain channel using a slipform paving machine, said concrete trench drain channel having frames defining an upper opening of said channel and adapted to receive a grate;
A frame for a concrete trench drain channel, said frame defining an upper opening of said concrete trench drain channel and adapted to receive a grate, wherein said frame is adapted for the continuous concrete slipforming of said concrete trench drain channel;
