Described sidewall punches transparent inner core and described urceolus with high.
The described sidewall transparent inner core that punches is of a size of inside radius 0.15m, the thick 0.01m of barrel, cylinder is high is 0.6m, the inside radius of described urceolus is 0.26m, the thick 0.01m of barrel, and cylinder is high is 0.6m, the radius of described base is 0.39m, thickness is 0.01 meter, and the radius of described top board is 0.15m, and thickness is 0.3m.
The measuring accuracy of described clock gauge is 0.001mm.
Adopt the solum settlement tester of technique scheme, first soil layer is filled according to certain scheme, then top board is positioned over to soil layer top, pressurize with jack pair top board, and conduct to soil layer, thereby reach the effect of simulating soil body gravity stress.Zeroing after clock gauge is contacted with top board, then control the water level between urceolus and the transparent inner core of punching by water inlet and water delivering orifice, water between urceolus and the transparent inner core of punching can immerse the soil layer in the transparent inner core of punching by the aperture on inner core sidewall, thereby reaches the effect of simulated groundwater immersion and discharge and underground water periodic cycle.This apparatus structure is reasonable in design, easily installs, easy to use, can simulate comparatively truly the solum settlement distortion under gravity stress effect above underground water periodic cycle and soil layer.
The test method of the solum settlement tester that the utility model provides, experimental procedure is as follows:
Whether step 1, checking experiment device be complete available, gets rid of the ponding in urceolus, and soil for setup test;
Step 3, open water inlet pipe, urceolus is filled up, and the soil body is reached capacity;
Step 4, top board is placed in to soil layer top, top board surrounding smears to keep its sealing and lubricity with vaseline;
Step 9, according to scheme, repeating step seven and step 8.
Above-mentioned steps six, step 7 and step 8 all adopt two pieces of clock gauges of installation jointly to measure, and the method for then averaging, to improve precision.
Adopt the solum settlement tester of technique scheme, innovation of the present utility model is: the design of punching on transparent inner core of solum settlement tester, can allow like this water infiltrate from the side the soil body, immersion and the discharge process of underground water are simulated more realistically, can regulate water level by water inlet and water delivering orifice, can carry out the simulation of underground water periodic cycle simultaneously.
The utility model can be measured the sedimentation of soil layer under the effect of underground water loop cycle and the solum settlement tester of resilience, carries out the solum settlement tester of Analysis on ground settlement especially for highway, railway and building field.Especially for solum settlement test and analysis existing in underground water periodic cycle situation, this experimental provision can be simulated the deformation situation of soil layer under gravity stress and under the effect of underground water loop cycle comparatively really, for follow-up stratum settlement research and analysis provides foundation.The utility model is a kind of for measuring device and the test method thereof of the solum settlement under underground water cycle variable effect, simulate the gravity stress on soil layer by the imposed load of controlling on soil layer, carry out the cyclical variation of simulate formation water level by the SEA LEVEL VARIATION of controlling between Inner, outer barrel, thereby obtain the solum settlement rule under underground water table cycle variable effect.
In sum, the utility model is a kind of solum settlement tester that can simulate comparatively truly the solum settlement distortion under gravity stress effect above underground water periodic cycle and soil layer.
