ABSTRACT:
Mobile continuous ditch lining apparatus includes a supporting portion, a raw material supplying portion, a mixing portion, a mixture delivery portion, a matrix forming portion and a control portion. The supporting portion includes at least one base section with a carriage. The raw material supplying portion includes a plurality of reservoirs connected independently with the mixing portion through flexible conduits. A blanket support extends from the supporting portion. The mixing portion includes an elongated chamber with a plurality of deflector sections. The matrix forming portion includes elongated mixture delivery and pressure applying mechanisms. The control portion includes a pump, a valve and a flow monitor along the length of each conduit, a drive advancing a continuous porous blanket through the matrix forming portion and a programmable memory.
A method of forming a ditch liner includes dispensing continuously a solidifiable liquid mixture uniformly over a continuously moving porous blanket. Pressure is applied thereto to form a continuous matrix therein. The rate of advance of the blanket is coordinated with the flow rate of the liquid mixture and the pressure applied thereto. The resulting liner is laid into a ditch continuously while still deformable and conformed and set in the configuration thereof. Also, the product formed with the above apparatus and method.
