<p>The present invention relates to a horizontal well drilling device with a hydraulic cylinder capable of increasing the diameter of an excavation case and the excavation length of the excavation case at the time of well drilling. The horizontal well drilling device with a hydraulic cylinder comprises: a drive motor which is coupled to one side surface of a support plate to provide rotational drive power; an auger member which is connected to the drive motor and rotates by the rotational drive power provided from the drive motor to excavate the ground; an excavation case which has a hollow formed therein to accommodate the auger member in the hollow and is inserted into the ground by the excavation of the auger member; a guide pipe which is inserted into the auger member and has a position tracking sensor formed on an end part thereof so that the excavation case tracks the direction that the excavation case excavates the ground; a direction switching unit controlling the direction that the excavation case excavates the ground; and four hydraulic cylinders which have one side fixed to the drive motor by compressing the excavation case toward the ground so that the excavation case performs excavation in the direction of ground bored by the auger member and the other side fixed to the excavation case. Therefore, the horizontal well drilling device with a hydraulic cylinder can be accurately constructed by controlling the direction of excavation of the front end of the horizontal well drilling device used to install a perforated drainpipe connected to an intake tube and can extend the diameter of excavation and the length of excavation by increasing the operation capacity of the hydraulic cylinder without increasing the diameter of the hydraulic cylinder.</p> |
