Definition - What does Control Parameter mean?
Control parameter can be defined as numerical values that are intrinsic to the controller design and affect the output of the controller on site. Trenchless construction techniques utilize data from existing records and current investigative reports to design the most desirable route for a trenchless drilling project for the purpose of installing pipelines. Having control parameters in place can help complete the project successfully while minimizing loss in terms of time and finances.
Trenchlesspedia explains Control Parameter
Any trenchless project using trenchless drilling techniques such as horizontal directional drilling (HDD), horizontal auger boring (HAB) or microtunneling are carefully designed around specific parameters in all stages of the project. The bore path will depend on parameters such as soil condition, presence of rock or other strata, presence of existing utility structures etc. passing through the planned path. These parameters become the controlling factor to design a route which is least obstructive and most economical. During the pullback process different control parameters come into play such as pullback velocity, starting acceleration, time required for execution and force during the pullback process. These parameters help contractors to decide the most suitable method, rig, cutter head or drill bit that will be required to carry out the project successfully.
