Embodiment Construction

[0050] Below, the present invention is described in detail with reference to accompanying drawing and embodiment:

[0051] Such as Figure 1~4 As shown, a bolt pullout test device considering the influence of temperature and pressure includes a base 6, a lower assembly plate 11 is arranged above the base 6, an assembly hole is formed in the lower assembly plate 11, and an assembly hole is set in the assembly hole. There is a workpiece cover 8 for making a test piece or a test piece cover 13 for airtight use. A high-strength glass sleeve 10 is arranged between the base 6 and the lower assembly plate 11. The base 6, the lower assembly plate 11, and the high-strength A closed temperature-controlled and pressure-controlled filling space is formed between the glass sleeve 10 and the test piece cover 13 .

[0052] The upper end of the base 6 and the lower end of the lower assembly plate 11 form an annular groove into which the high-strength glass sleeve 10 can be inserted, and a wa...

Abstract

The invention discloses an anchor rod pull-out test device and test method considering temperature and pressure influences. The test device comprises a base, a lower assembly plate is arranged above the base, a workpiece sleeve or a test piece cover is arranged in an assembly hole in the lower assembly plate, a high-strength glass sleeve is arranged between the base and the lower assembly plate, and a closed temperature-control and pressure-control filling space is formed among the base, the lower assembly plate, the high-strength glass sleeve and the test piece cover; the test method comprises the following steps: mounting the test device, filling the test device into a soil body, compacting the soil body, coating the soil body with a rubber film, grouting, inserting reinforcing steel bars, pressing and covering a test piece, and carrying out a pull-out test. The medium-high strength glass sleeve can form a filling space for temperature and pressure control, a manufactured test pieceis subjected to a temperature and pressure control test through a pipeline, the test piece is pressed through a lifting type middle lifting plate, compaction and drawing can be achieved through the pressing piece on a top pulling and pressing plate, and temperature and pressure influence factors are added to the test.

Description

technical field [0001] The invention belongs to the technical field of anchoring tests under complex conditions, and in particular relates to an anchor pullout test device and a test method considering the influence of temperature and pressure. Background technique [0002] Anchorage technology is widely used in today's engineering construction field. It has been favored by the engineering community for its outstanding advantages of reliable force, flexible construction, small interference to rock and soil, safe operation and quick results, and has almost touched the field of geotechnical engineering. Every corner: slope stabilization engineering, such as slope reinforcement, slope stability, retaining wall anchorage, landslide prevention, etc.; deep foundation pit engineering, such as basement support, anti-tilting and anti-floating of underground parking lot, stability of underground railway or underground passage, etc. ; Structural engineering to resist overturning, such ...
