Background
Horizontal directional drilling machine construction principle: the directional drilling equipment is used for starting directional drilling at the entrance, and the drilling is extended according to the designed track by monitoring and control means in the drilling process. And drilling the earth surface from the other end to finish the construction of the guide hole. And if the pipeline to be installed of the drilling machine is large, the step-by-step reaming is carried out when the reaming and the back-towing operation cannot be completed simultaneously, and the diameter of each reaming is determined according to the equipment capacity, the stratum condition and the site condition. A pullback reamer may be generally employed. The pipeline back-dragging is that the directional drilling machine connects the pipeline to the drill rod at the outlet through the back-dragging head, the reaming bit and the transfer case, and the drilling equipment rotates and simultaneously drags back, and simultaneously, flushing fluid is conveyed to the reaming bit through the drill rod, and the reaming back-dragging process is continuously carried out. Long-time non-operation pauses are not allowed in the middle, etc.
The directional drilling machine technology is an advanced technology developed from the petroleum drilling field, and is a construction technology for paving public pipelines such as water supply, gas, natural gas, sewage, telecommunication cables and the like under the conditions of no digging grooves on the ground surface and minimal damage to stratum structures by using the technical means of rock drilling, directional drilling machine measurement and control and the like. The directional drilling machine has wide application range, can adopt a hole bottom motor or a rigid drill rod to drive a drill bit to rotationally drill and hole, and can also perform construction in hard rock or pebble layers.
In the control process of a general directional drilling machine, the operation condition of each component of the directional drilling machine can be monitored in real time due to the fact that the operation condition of the directional drilling machine is easily affected by the operation condition and the construction site, whether each component of the directional drilling machine fails or not can be accurately judged, and the failure of each operation component of the directional drilling machine is easily caused due to the fact that the construction environment of the directional drilling machine is severe, so that a great amount of time and labor cost are consumed for overhauling or maintaining the directional drilling machine.
To sum up, we propose an intelligent control system and method based on directional drilling machine.
