Foot-pedal type compaction fixing device of soil-sample saturator

Abstract

The invention relates to a foot-pedal type compaction fixing device of a soil-sample saturator, belongs to the technical field of geotechnical test instruments and equipment and is designed for solving the problems that soil-sample manufacture and compacting operation is complex, the saturator is hard to fix and forming quality of a soil sample is poor. The foot-pedal type compaction fixing device mainly comprises a saturator fixing sleeve and a ring-shaped foot pedal, wherein each of the saturator fixing sleeve and the ring-shaped foot pedal is formed by machining a steel plate which is 3mm thick; the saturator fixing sleeve is a semi-closed hollow steel cylinder with an opening in one end and a round hole in the center of the other end, and is 80mm in outer diameter and 56mm in height, and the diameter of the opening in the semi-closed end is 50mm; the ring-shaped foot pedal is welded at the bottom end of the opening of the saturator fixing sleeve and is 400mm in outer diameter. The foot-pedal type compaction fixing device has the advantage that the structure is simple, the cost is low, the operation is convenient, the practicability is strong, and not only the labor is saved, but also the soil-sample manufacturing quality can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of geotechnical testing instruments and equipment, in particular to a soil sample saturator fixing device, in particular to a foot-operated soil sample saturator compaction fixing device. Background technique [0002] In the process of civil engineering practice and theoretical research, in order to measure the mechanical properties of soil such as strength, deformation and pore water pressure, indoor static triaxial tests, dynamic triaxial tests and unconfined compressive strength tests are generally used. The quality of preparation is an important factor affecting the accuracy of the test. Generally speaking, soil samples are obtained by compacting layers in a soil sample saturator, but there are many inaccurate factors in the actual operation of soil sample preparation.

In general, soil samples are obtained by compaction in layers in a soil sample saturator, but there are many inaccurate factors in the actual operation of soil sample preparation

In the traditional soil sample preparation process, usually two people are required to coordinate the operation manually, one of them holds the soil sample saturator with his hand, and the other performs layered soil compaction, which not only wastes manpower greatly, but also takes The position of the soil sample saturator is easy to move due to the effect of the impact force during the solidification process. At the same time, due to the need for repeated compaction of layered soil, the soil sample saturator will not be in close contact with the ground, resulting in some soil particles falling from the ground. The overflow in the gap at the bottom of the soil sample saturator will cause large errors in the preparation of soil samples. Therefore, it is necessary to invent a new fixing device for the soil sample saturator to facilitate and effectively prepare the soil samples.
