Problems solved by technology

[0004] However, under the background of the existing technical conditions, in the process of simulating rainfall on the expansive soil foundation, the artificial sprinkler method is mostly used, because the spraying method of the sprinkler is limited by the slope angle of the channel, and it is very easy for the sprinkler to tip over. question
The artificial watering method is greatly affected by human factors, and the problem of uneven watering often occurs, resulting in poor reliability of test results

Abstract

The invention relates to an on-site simulated rainfall test device for high filling expansive soil foundation, which comprises two tracks for laying on the embankment, and the bottom of each track is equipped with a slope adjustment mechanism that can adjust the slope of the bottom surface. The top of the track is equipped with wheels that can move along the length direction, the wheels are connected with wheel motors, the upper part of the wheel frame is connected with liftable outriggers, and the top of the two sets of outriggers is bridged with a sprinkler system. Utilizing the characteristics of the adjustable track bottom slope and the liftable legs, the whole set of test equipment can be applied to the canal embankment with different slope requirements, and then the sprinkler system is located at the top to simulate the effect of rainwater falling from top to bottom and infiltrating the embankment , thus realizing the characteristics of simulating rainfall without manual watering, reducing the labor intensity of workers in the test process, and improving the accuracy of test results.

Description

technical field [0001] The invention belongs to the field of channel exploration, in particular to an on-site simulated rainfall test device for high fill expansive soil foundation. Background technique [0002] At present, it is widely used in expansive soil high filling operations in channel construction. Expansive soil is a kind of clay with multiple cracks, expansion and contraction, and super-consolidation, which is widely distributed at home and abroad. The water infiltration and volume change of multi-fissure unsaturated expansive soil is an extremely complicated hydraulic-mechanical process. At present, there is no mature pure theoretical method that can be used to calculate the expansion-contraction deformation performance of expansive soil foundation. Laboratory experiments and The actual engineering on site has a large gap, and it is difficult to fully reflect the true properties of the undisturbed expansive soil under the condition of water infiltration. [000...
