AI Technical Summary
Technical Problem
The existing technology cannot conduct in-pipe pressure bearing capacity testing on site, and the existing test methods cannot truly reflect the pipeline's resistance to internal and external pressure.
Method used
An equipment for wheel-pressure load test evaluation of pipeline bearing capacity is designed, including reference beams, reaction frames and wheel set pairs. Pressure equipment is used to apply pressure on the inner wall of the pipeline and equipped with displacement monitoring sensors, which can be tested on site.
Benefits of technology
The pipeline bearing capacity is tested in situ at the project site, which can more accurately reflect the pipeline's internal and external pressure resistance and provide a faster test method.

Abstract
The invention relates to equipment for evaluating the bearing capacity of a pipeline through a wheel pressure method load test. The equipment comprises a datum beam, a counter-force frame and a plurality of wheel set pairs, the wheel set pair comprises two wheel sets which are symmetrically arranged relative to the axis of the reaction frame; the wheel set pair is mounted on the outer side of the counter-force frame through pressurizing equipment; the reference beam is provided with an independent support; and a plurality of displacement monitoring sensors are arranged between the inner wall of the test pipeline and the datum line beam. According to the equipment for evaluating the bearing capacity of the pipeline through the wheel pressure method load test, different mechanical properties of the pipe wall can be tested through asynchronous loads of a plurality of wheel sets, and the internal and external pressure bearing capacity resistance of the pipeline can be better reflected. The equipment has the characteristics of wheel sets, can be loaded and can move quickly, and a quicker method is provided for tests. Advance measurement can be carried out under a fixed pressure load condition; and after a plurality of load cycles, a certain step length can be carried out for measurement.
