Horizontal sliding type soil arching effect tester and usage thereof

Abstract

The invention relates to a horizontal sliding type soil arching effect tester and a usage thereof. The horizontal sliding type soil arching effect tester comprises a test box and a lifter; a structural unit plate and a nonstructural unit plate are arranged on the bottom of the test box; the lifter comprises a lifting power device, a top tube platform plate and a top tube; the top tube platform plate can go up and down by means of the lifting power device; and the top tube can slide in a slide way of the top tube platform plate. The usage of the horizontal sliding type soil arching effect tester includes: adjusting the position of the top tube, raising the top tube to fix the structural unit plate, and gradually lowering the structural unit plate to simulate an actual working condition. When adopted to carry out a test to compare soil arching effects of culverts at different positions, the horizontal sliding type soil arching effect tester and the usage disclosed by the invention have the effects of time and labor saving, economy, accurate results and the like.

Description

technical field [0001] The invention relates to the field of water conservancy engineering test equipment, in particular to a horizontal sliding type soil arch effect test device and a use method thereof. Background technique [0002] Soil arching effect is the most common phenomenon in nature. It is a factor that needs to be considered in hydraulic engineering and construction engineering. Due to the existence of soil arching effect, the distribution of earth pressure on structures will be significantly affected. [0003] In recent years, more and more calculation methods considering the soil arching effect have been proposed. However, the progress of related experiments is relatively slow, especially the soil arch effect experiment under the condition of multiple culverts. The reason is that the development of experimental research devices is relatively slow. [0004] For culverts, the general research is limited to the research on the middle part of the excavated backfil...

However, the progress of relevant tests is relatively slow, especially the soil arch effect test under the condition of multiple culverts. The reason is that the development of test research devices is relatively slow

[0004] For culverts, the general research is limited to the research on the middle part of the excavated backfill surface, while for the central axis of the culvert, the distance from the left side of the backfill surface is 1 / 5, 1 / 4, 1 / 5 of the total width of the excavated surface The effect of positions such as / 3 has not been studied

According to the existing test equipment, if a comparative test is to be carried out, the test device basically needs to be redesigned and manufactured every time a test is done, the test device has insufficient versatility, and the cost of each test is relatively high

This factor directly restricts the test efficiency and further restricts people's understanding of the soil arch effect.
