A test monitoring device for water and salt migration in saline soil

Abstract

The invention discloses a test monitoring device for water-salt migration in saline soil, comprising: a base, a simulation detection box is fixedly installed on the top of the base, and a rainwater simulation mechanism is fixedly installed on the top of the simulation detection box. A water supply mechanism is fixedly installed on the right side inside the analog detection box, and a semiconductor refrigerator is fixedly installed on the upper left side of the analog detection box, and the right output end of the semiconductor refrigerator is connected with the left side of the internal group of the analog detection box. Telescopic legs are fixedly installed on both sides of the bottom of the simulated detection box, a detection mechanism is hinged between the tops of the telescopic legs, and shock-absorbing legs are fixedly installed at the four corners of the bottom of the base; Simultaneously, it is more convenient to use, has strong operability, and has wide application prospects. It fills the vacancy of the test monitoring device for water and salt migration in saline soil. It has strong practicability and wide application prospects, and is worthy of promotion and use.

Description

technical field [0001] The invention relates to the technical field of monitoring water and salt migration of saline soil, in particular to a test monitoring device for water and salt migration of saline soil. Background technique [0002] Saline soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soil in which the soluble salt content in the soil reaches a significant hazard to crop growth. As a special soil, saline soil is widely distributed in my country and is a special soil with environmental sensitivity. Changes in water and temperature. In the road construction in the saline soil distribution area, the route will inevitably pass through the saline soil section, and encounter many technical problems related to the engineering characteristics of saline soil; [0003] When saline soil is used as roadbed filler, under natural precipitation environment, the migration of water and salt in saline soil ro...

Problems solved by technology

In order to ensure the normal operation of saline soil subgrade, it is necessary to study the water and salt migration law of saline soil subgrade and the law of saline soil strength attenuation after water and salt migration. , there is a lack of relevant experimental monitoring devices for water-salt migration in saline soils, and the existing experimental monitoring devices for water-salt migration in saline soils are not convenient for simulating different climates, and thus inconvenient for experimental detection. Therefore, we propose a An experimental monitoring device for water-salt migration in saline soils to solve this problem
