Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of oedometer, specifically is a lever type oedometer. BACKGROUND

[0002] In the field of civil engineering, the consolidation characteristics of soil are very important. Consolidation test is an important means to obtain key parameters such as compressibility and permeability of soil. During the test, it is necessary to accurately apply stable vertical pressure to the soil sample. However, many oedometers are prone to pressure fluctuations during loading, which can seriously affect the accuracy of the test results. Moreover, the traditional oedometer has poor operational convenience, and the test personnel need to spend a lot of time and effort in installing the sample and adjusting the loading device. Therefore, some new oedometers have appeared on the market.

[0003] For example, the Chinese patent with publication number CN210803144U discloses a single lever type oedometer, which includes a digital dial gauge, a consolidation device, a lever, a lifting platform, and a lever type oedometer. The utility model installs a lifting platform on the equipment base, which can effectively reduce the impact force and disturbance to the sample when manually applying weights. After applying the load, immediately open the stopwatch to observe the changes of the soil sample, which can reduce the error when applying the weight. The utility model uses a positioning groove at the position of the hook, so that the weight disc support rod can be firmly fixed in the positioning groove. This increases the double reduction of shaking when adding weights, which can greatly reduce the error. A laser pen placement hole is provided in the support frame, and a laser pen can be placed in the laser pen placement hole. After turning on the laser light, a parallel laser beam is emitted. This beam can be used as a tool for auxiliary calibration standard. The laser pen itself is low in cost and efficient in calibration. It can be used as needed, reducing the error when adjusting the lever balance.

[0004] The lever type oedometer provided by the above-mentioned patent uses weights to apply different vertical pressures to the soil sample through the lever, so as to determine the relationship between axial deformation and pressure and the relationship between deformation and time of the soil sample. In actual work, according to the experimental requirements, the vertical pressure range is 12.5-1200KPa / 30cm 2 Therefore, the staff needs to add weights at intervals, which is very troublesome and increases the workload of the staff. Therefore, there is a need for an oedometer that can automatically add weights to the lever on the market. UTILITY MODEL CONTENTS
