Downhole Anchor Pile Theoretical Analysis And Experimental Study Of Ultimate Bearing Capacity

Workover of downhole equipment, and its main bear part of the load is operating derrickderrick operating the derrick space steel structure, so you need to land anchor and guy wire asauxiliary support.. The fixed derrick the land anchor the oil pipe pile Ф76.2mm, length of2500mm, car pile-driver hammer hard into the soil, and then connect guy wire to secure thederrick. The workover rig derrick safety evaluation, most researchers derrick only the mainstructure stress analysis, often neglected to anchor this part, rarely take into account the thederrick structure carrying capacity ground anchor relationships.Anchor In this paper, the mechanical characteristics, according to the actual needs ofthe work site, through the study of soil mechanics and related literature scholars, summed upthe application of theory to anchor pile bearing capacity formula. Inherited by the detectionanchor pile bearing capacity, further summary and sorting out the the transient mechanicalimpedance method to anchor the ultimate bearing capacity of the test methods and formulas,and through the on-site test, achieved a better effect. Research methods, finite elementsoftware, combined with the pile-soil constitutive model and yield criterion side, respectively,through the method of two-dimensional and three-dimensional modeling, to anchor ultimatebearing capacity of the preliminary study of the finite element method.
