A test and detection device for highway lime improved soil

Abstract

The invention provides a test and detection device for highway lime improved soil, which includes a base, a sorting box, a detection box and a liquid storage box are arranged on the upper surface of the base, and a U-shaped frame is arranged inside the sorting box. The two inner sidewalls of the sorting box are fixedly connected with first T-shaped bars, both ends of the U-shaped frame are provided with cavities, one end of the first T-shaped bars is located inside the cavity, and the first The outer surface of the T-shaped bar is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected with the side wall of the U-shaped frame and the inner wall of the sorting box, and the middle part of the U-shaped frame is provided with a blanking port . The invention occupies a small space, is easy to operate, improves the accuracy of the test and detection by rolling and screening, and can automatically detect the chemical properties of the improved soil, improving the detection efficiency, and at the same time giving the physical properties of the improved soil. The detection test provides help, shortens the operation steps of manual detection, thereby improving the overall test detection efficiency.

Description

technical field [0001] The invention relates to the technical field of improved soil, in particular to a test and detection device for road lime improved soil. Background technique [0002] The engineering geological properties of soil directly related to engineering buildings are mainly water permeability and mechanical properties (compressibility and damage resistance), and they depend on the material composition and structural characteristics of soil. Therefore, soil improvement is essentially to improve the properties of soil by changing the composition and structure of soil. Modified soil is divided into physical modified soil and chemical modified soil. Physical modification is to change the particle size by adding crushed stone, etc., and chemical modification is to improve engineering by adding lime, cement, fly ash and other curing agent materials. performance soil. Before the lime-improved soil is used, it is necessary to test the various indicators of its physic...
