Modular ultra low drag sub-surface membrane installation apparatus, machine, and methods with various automated and semi-automated sub-systems including sub-surface drip tape installation

A sub-surface membrane deposition device comprising:

• a movable frame;
• at least one chisel attached to the frame;
• hydraulics to raise and lower the at least one chisel from the frame;
• and,
• a membrane deployable to a sub-surface level by the at least one chisel as the movable frame is moved;
• wherein the chisel includes a forming cone that dispenses the membrane in a wrinkle-free condition;
• wherein the forming cone includes a ten-degree angle at a bottom front edge of the forming cone that engages the membrane at non-equal points.

A method of deposing a membrane to a sub-surface level comprising:

• providing a movable frame, at least one chisel attached to the frame, hydraulics to raise and lower the at least one chisel from the frame, and a membrane;
• lowering the at least one chisel with the hydraulics to the sub-surface level;
• moving the frame and at least one chisel forward;
• deploying the membrane to the sub-surface level with the at least one chisel;
• wherein the device performs high-speed installation by cutting the membrane with a perforator disposed at the frame and by using a quick changeover shaft assembly to end and start membrane deposition through remote operation of the device.
