A mountainous region rotary drilling rig operation applicability discrimination method based on a design scheme

By using a design-based approach that combines geological lithology, equipment parameters, and terrain assessment, the applicability of rotary drilling rigs in overhead power transmission line construction is determined. This solves the problem of low accuracy caused by reliance on experience, ensures that the equipment can be successfully brought to the site and operated, and reduces construction risks and costs.

AI Technical Summary

Technical Problem

In the existing technology, the determination of whether rotary drilling rigs are suitable for overhead power transmission line construction mainly relies on the experience of technical personnel, which has the problems of strong subjectivity and low accuracy, resulting in the inability of the equipment to enter the site or to operate smoothly after entering the site.

Method used

By determining the lithology and rock strength of the strata at the tower site through drilling and geotechnical tests, and combining the power output torque and equipment parameters of the rotary drilling rig, a method is provided to determine whether the equipment can enter the site and operate. This includes the assessment of road width, slope, terrain flatness and foundation bearing capacity.

Benefits of technology

During the design phase, ensure the accuracy of the suitability assessment for rotary drilling rigs to avoid equipment being unable to enter the site or operate, thereby reducing the cost of mechanized construction and improving construction efficiency and safety.

Abstract

The application discloses a mountain rotary drilling rig operation applicability discrimination method based on a design scheme, determines tower site stratum lithological distribution characteristics and rock uniaxial saturated compressive strength according to actual tower site positions, determines rotary drilling rig power output torque and selects a rotary drilling rig model according to rock uniaxial saturated compressive strength of a bearing stratum at a position corresponding to a predicted foundation pile length, determines equipment width and maximum climbing ability, discriminates whether equipment built road section access conditions are met in combination with built road width and maximum longitudinal slope conditions, judges whether the rotary drilling rig has new temporary road access conditions in combination with a relative position relationship between the tower site and the built road and temporary roads, judges whether tower site terrain flatness difficulty is suitable for rotary drilling rig operation in combination with the tower site terrain slope, rechecks whether the foundation bearing capacity meets equipment operation requirements, and reduces the possibility that the equipment cannot access or cannot operate after accessing in a construction implementation process from a design source.
