AI Technical Summary
Existing static filling performance testing devices for expansion-type borehole fillers have problems such as inaccurate monitoring of expansion pressure and temperature rise history, sensor damage due to off-site loading and handling affecting measurement accuracy, and lack of universal support frames for multiple aperture sizes, making it difficult to achieve synchronous and accurate monitoring of "thermal-mechanical" parameters and multi-aperture adaptation.
A testing device comprising a steel pipe, a sliding support rod, a clamping assembly, and a force transmission rod was designed. Combined with a water tank cooling system, the sensor achieves targeted temperature control. The device is adapted to expansion-type borehole fillers of different diameters through a relatively sliding support rod, and expansion pressure and temperature data are collected simultaneously. This constructs a system that integrates expansion pressure testing, reaction temperature monitoring, and interface static friction testing.
It improves the accuracy and reliability of tests on expansion-type borehole fillers, reduces the influence of strain gauge thermal drift, enables unified testing and evaluation of products of different specifications, and ensures the engineering representativeness and comparability of test results.
