Direct torque helical displacement well and hydrostatic liquid pressure relief device
A helical displacement well with preassembled segments includes a preassembled shaft-forming penetrator tube including helical plates mounted to its exterior that may be rotated to propel the casing into the ground. A hydraulic drill motor rotates the penetrator tube as it moves deeper into the ground. Extension tubes may be added to and coupled to the penetrator tube. A bolt including a threaded stem sized to engage the threaded bolt opening of the male connector and a cap of larger breadth than the threaded stem and sized to fit within the unthreaded tension bolt opening of the female connector for connecting the female connector about the male connector.
