A portable cofferdam system for isolating a working area from water such as a culvert. The portable cofferdam system generally includes a first sidewall and a second sidewall each having an interior side, an exterior side, an upper edge, a lower edge and a rear edge. A middle wall is connected to the sidewalls opposite of the rear edges of the sidewalls forming a substantially U-shaped structure. An opening formed between the rear edges of the first sidewall and the second sidewall to allow for positioning about or near the inlet of an object or area to be kept dry such as the inlet of a culvert.
A CIPP liner reel system for managing the utilization and deployment of CIPP liners. The CIPP liner reel system generally includes a frame connected to a reel and drive unit. The drive unit is connected to the reel to control the rotation of its core. This core contains an opening that provides access to a connector unit within the core. This connector unit can be used to connect the reel to the end of a CIPP liner using a strap. Rotation of the core causes CIPP liner to wind on to or unwind from the reel. The reel may also contain a left guide member and a right guide member to assist in controlling the process of winding and unwinding the CIPP liner. The frame may also include a tractor connector that enables the CIPP liner reel system to be coupled to and transported by a tractor without affecting its operation.

A CIPP liner feed roller for manipulating and feeding CIPP liner by pulling CIPP liner from a liner source and feeding it to where it is needed. The CIPP liner feed roller generally includes a main roller attached to a frame, a clamping roller attached to the frame and configured to be in parallel with the main roller, wherein the distance between the clamping roller and the main roller can be adjusted using one or more actuators, a drive unit comprising a motor configured to control the rotation of the main roller within the frame, a controller coupled to the drive unit and the one or more actuators, wherein the controller is configured to control the rotation of the main roller and the distance between the clamping roller and the main roller, and a support beam attached the frame and configured to be in parallel with the main roller.
A system for assembling a cofferdam. In a first example embodiment, a cofferdam may be assembled on-site using a plurality of walls that couple each other to form the cofferdam. In a second example embodiment, a plurality of walls and a plurality of connectors may be assembled to form the cofferdam. The walls and/or connectors disassembled for transport and/or storage, yet quickly assembled on-site to form the cofferdam. The panels and/or the connectors may form cofferdams of various shapes and sizes. The walls and/or connectors are made of a durable material that permits multiple uses. The cofferdam may be assembled to hold back the water of a body of water from around a culvert while work or repairs are performed.
