Automatic device for evenly wetting soil and soil wetting method thereof

Abstract

The invention discloses an automatic device for evenly wetting soil and a soil wetting method thereof. The automatic device comprises a horizontally-arranged bottom plate. A soil vibrating device and a soil wetting spraying device are arranged on the upper surface of the bottom plate. The soil vibrating device comprises a vibrator and a soil-sample containing device; the vibrator comprises a vibrator body and a vibrating platform located at the top of the vibrator body; the soil-sample containing device comprises boxes and box covers, wherein the boxes and the box covers are placed on the vibrating platform. The soil wetting spraying device comprises a water tank, a water pump and a spraying head, wherein the spraying head is fixedly connected to the box covers, the water inlet end of the water pump is communicated with the bottom of the water tank through a water inlet pipe, and the water outlet end of the water pump is connected with the spraying head through a water outlet hose. According to the automatic device, an automatic control device for wetting soil is set, the water consumption is automatically calculated according to the water content obtained before soil wetting and the water content obtained after soil wetting, and the automation degree of the configuration is increased; meanwhile, wetting is carried out in the mode that soil is vibrated while spraying, so that after arrangement is completed, the soil is more evenly wetted, and the water content is more accurate.

Description

technical field [0001] The invention relates to the field of soil engineering tests, in particular to an automatic device for uniform soil wetting and a soil wetting method thereof. Background technique [0002] Shear strength is one of the soil mechanics indexes, which is of great significance to the research of rock mechanics and the practice of geotechnical engineering. Soil moisture content is one of the important factors affecting soil shear strength. At present, the measurement of soil shear strength is usually done by triaxial test. When making triaxial test soil samples, it is necessary to configure soil samples with different moisture contents, so the exact configuration is different. Soil samples with moisture content are extremely important. The traditional configuration method is: weigh a quantitative soil sample, spread the soil sample on the enamel plate, calculate the required water amount according to the required moisture content, measure the quantitative w...

Problems solved by technology

This method is all manually operated by experience, which is time-consuming, and the operation accuracy is not high, and the moisture content of the configuration is not accurate enough. The infiltration of the soil sample is only wet on the surface, and the internal moisture of the soil sample cannot be guaranteed, so that the infiltration of the soil sample is not uniform enough, resulting in large test error
