Embodiment approach

[0056] In order to study the collapsing mechanism of loess under the action of washing and replenishing salt, it is necessary to study the undisturbed soil on the road site, and the present invention's implementation method to undisturbed soil is as follows:

[0057] ① Lay a layer of plastic sheet 22 of the same size on the heat insulation bottom plate 4, place the stainless steel soil sample cylinder 1 with reserved holes on the side wall on the plastic sheet 22, and place the soil sample cylinder 1 with the plastic Apply a circle of glass glue to the thin plate 22 contacts to prevent leakage (in order to ensure that the heat-insulating base plate 4 is not crushed during the filling of the soil sample, the heat-insulating base plate 4 should adopt a higher foam glass heat-insulating layer of strength); Wrap the heat transfer conduit 6 around the outer circumference of the soil sample cylinder 1 (be careful not to press the heat transfer conduit 6 against the reserved hole on t...

Abstract

The invention relates to a temperature-controllable salt leaching-adding soil test device and a method for testing a soil sample by using the same. The invention mainly aims to solve the technical problem in a current quantitative loess research method that great error exists between test data and an engineering entity. The technical scheme adopted by the invention is characterized in that the temperature-controllable salt leaching-adding soil test device consists of a soil sample barrel, a temperature control system, a salt leaching-adding system, a pressuring device and a data acquisition system. The method for testing the soil sample by using the device comprises the following steps: 1) the moisture content and the soluble salt content of the soil sample are tested; 2) the soil sample is charged into the soil sample barrel; 3) weight is applied to the pressuring plate; 4) the soil sample is heated; 5) a salt solution or water is added to the soil sample; 6), 7) and 8) the temperature is raised, lowered and then is raised, and the deformation situation of the soil sample is recorded; 9) distilled water is added to the soil sample with a water (salt) supplying container, and the deformation situation of the soil sample is recorded; 10) discharged water is collected with a collection container; the conductivity of the discharged water is tested; and the deformation situation of the soil sample is recorded.

Description

technical field [0001] The invention belongs to the technical field of geotechnical testing, and specifically relates to a temperature-controllable washing-salt-supplementing soil test device and a method for testing soil samples, especially capable of dynamically observing soil moisture, salinity, Dynamic changes in temperature and deformation. Background technique [0002] About 65% of the highway mileage in my country's loess distribution area is distributed in the collapsible loess area. Due to the limited level of early loess roadbed treatment technology, coupled with the extreme climate (such as heavy rainfall) caused by the greenhouse effect and the artificial development of agriculture Factors (such as seasonal irrigation and the intrusion of external salt) have changed the operating environment along the road, making the roadbed always in the operating state of strong increase and decrease of humidity and washing and replenishing salt cycles, which eventually lead to...
