Problems solved by technology

Since the binder is relatively small and belongs to a polymer compound, it is generally difficult to directly measure the change of its content from the soil. It is necessary to take the soil to a special research institute for measurement, which is cumbersome and complicated for engineering.

Abstract

The invention relates to a soil adhesive content tester, and belongs to the technical field of rock-soil mechanical experimental instrument manufacturing. The tester is mainly composed of a cylindrical main body, a pH sensor, an electric conductivity sensor, a servo motor, a programmable system, an up-and-down motion controller, an up-and-down feeding distance controller, a data display screen, acontrol panel and a movable support. The tester is a novel testing device and can measure the content of an adhesive in soil; and the degradation process of the adhesive in the soil is reflected by the change of the content of the adhesive, so that the research on the performance of the adhesive is facilitated.

Description

Technical field: [0001] The invention relates to the field of geotechnical engineering, in particular to a soil binder content tester. The tester can be inserted directly into the soil to measure the binder content of the soil. Background technique: [0002] Soil and water conservation is the basis of vegetation restoration. Generally, materials that do not fall off, do not run off, and have a certain degree of anti-scourability are used. Therefore, it is necessary to choose a binder to flocculate soil particles and form an aggregate structure from small to large. At present, the binder used is a water-soluble organic soil conditioner polymerized by high-molecular-weight polyacrylamide, which has strong sedimentation and flocculation of soil particles, and forms a good aggregate structure in the soil, so it constitutes an anti-scour , Anti-leakage carrier. It can be mainly used for green spraying, afforestation, etc. It has the characteristics of preventing soil loss caus...
