Problems solved by technology

At present, the preparation of soil samples is mostly done by saturators, but due to structural design defects, the existing soil saturators usually have to be used by two operators, one of whom fixes the saturator, and the other layer Filling and compacting the soil, there are technical problems such as low operation efficiency, high labor intensity, complicated operation process, waste of labor, and difficulty in ensuring the accuracy of soil sample preparation

Abstract

The invention discloses a semi-automatic soil saturator and belongs to civil engineering experimental apparatuses. A motor and a lead screw are arranged at the bottom in a saturator shell cavity; a driving gear and a driven gear are respectively and fixedly arranged on the motor and the lead screw; a cylindrical mold is assembled on the lead screw in an up-and-down moving manner; a vibratory tamper is fixedly arranged on the bottom end of a shaft lever and arranged in the cylindrical mold in an up-and-down moving manner; a soil sample chamber is formed by an inner cavity of the cylindrical mold and the saturator shell cavity on the lower part of the vibratory tamper; a vibrating rod sleeves the shaft lever in an up-and-down moving manner; and an electromagnetic coil is fixedly arranged at a position, which is positioned on the outer side of the vibrating rod, of the upper part in the saturator shell cavity. The saturator is novel, reasonable and simple in structure, the semi-automatic operation is realized, the operation is simple and convenient, the operators are saved, the labor intensity is low, the soil sample preparation precision is high, and the operation is stable and reliable.

Description

technical field [0001] The invention belongs to civil engineering experiment instruments, and mainly relates to a soil saturator. Background technique [0002] In civil construction design, the determination of soil pore water pressure, strength and other characteristics is a technical basic work that must be completed, and the quality of soil sample preparation is crucial to the accuracy of characteristic determination experiments. At present, the preparation of soil samples is mostly done by saturators, but due to structural design defects, the existing soil saturators usually have to be used by two operators, one of whom fixes the saturator, and the other layer Filling and tamping have technical problems such as low operating efficiency, high labor intensity, complicated operation process, waste of labor, and difficulty in ensuring the accuracy of soil sample preparation. Contents of the invention [0003] The purpose of the invention is to design a semi-automatic soil...
