【 摘 要 】

In order to design more accurately trenchless pipeline passages, a technique has been developed for calculating the passage profile, based on specific parameters of the horizontal directional drilling rig, including the range of possible drilling angles and a list of compatible drill pipe sets. The algorithm for calculating the parameters of the trenchless passage profile is shown in the paper. This algorithm is based on taking into account the features of HDD technology, namely, three different stages of production. The authors take into account that the passage profile is formed at the first stage of passage construction, that is, when drilling a pilot well. The algorithm involves calculating the profile by taking into account parameters of the drill pipes used and angles of their deviation relative to each other during the pilot drilling. This approach allows us to unambiguously calibrate the designed profile for the HDD rig capabilities and the auxiliary and navigation equipment used in the construction process.
