Embodiment Construction

[0035] Such as figure 1 , the curing box structural unit of each prefabricated curing box 2 is a cuboid, and three double-layer saturators 1 are usually placed in the curing box structural unit, and the number of double-layer saturators 1 can be customized and increased according to actual needs. The samples prepared by each curing box structural unit are cured at the same temperature, time or pH, which is convenient for repeated verification and sample preparation for subsequent further analysis. The curing conditions of the samples prepared by different curing box structural units are different, which are determined according to different experimental purposes. There are more than three structural units of the curing box, which can be increased or decreased according to actual needs, and are plugged into each other and have the same height. A waterproof adhesive tape is pasted on the junction of the circuit base plate 21, the constraint side plate 22 and the variable contro...

Abstract

The invention discloses a sample preparation maintenance device for strength timeliness of the steel slag; the device comprises a double-layer saturator and an assembly type maintenance box, the assembly type maintenance box is used for sample maintenance in the double-layer saturator, the double-layer saturator comprises a base, an outer saturator, an inner saturator, a top seat and a permeable pressure sample block, and the base is connected with the outer saturator. The inner saturator is nested inside the outer saturator, the inner side of the inner saturator is used for placing a sample, and one side, different from the base, of the sample is connected with the top seat or the permeable pressure sample block. The invention further discloses a use method of the sample preparation and maintenance device for improving the strength timeliness of the steel slag. Through the constraint of the outer saturator of the double-layer saturator, the problems that in the sample preparation process, due to insufficient constraint, the upper portion and the lower portion of a sample are different, and the saturator is broken are solved; demolding is more flexible and convenient, demolding is achieved by sliding the inner saturator, and damage and deformation of a sample can be effectively avoided; particle materials which are difficult to form can be cured, the curing environment can be easily controlled to be the same, and unnecessary errors of experiments are avoided.

Description

technical field [0001] The invention relates to a sample preparation and maintenance device and a use method thereof, in particular to a sample preparation and maintenance device with steel slag strength and timeliness and a use method thereof. Background technique [0002] Indoor geotechnical test is an important content and a necessary way to study soil physical and mechanical parameters, and provides an important basis for correct decision-making in geotechnical engineering design and construction. Steel slag is a derivative in the steel production process. Due to the influence of the minerals contained, these components will undergo unstable changes after contact with water, thus limiting the reuse of steel slag materials. The application of steel slag is increasing day by day, and the research on the mechanical properties of steel slag also needs further development. However, due to the difficulty of forming steel slag, it is difficult to use experimental instruments to...
