Background

The development of modern society leads the demand of petroleum energy to be continuously increased, and under the background condition, exploration and development of petroleum energy per se are accelerated by various countries. As petroleum is produced, refined, stored, transported, used, processed, etc., crude oil and petroleum products are spilled or leaked at or below the surface.

The physical, chemical and thermal mechanical properties of the soil polluted by petroleum can be obviously changed, which causes serious environmental pollution and certain environmental geotechnical engineering problems. In order to study the environmental pollution problem and the stability problem of the engineering, the parameters involved in the above problems can be studied by preparing a sample of the petroleum-contaminated soil indoors.

Due to the difficulty in sampling the undisturbed petroleum polluted soil and the regional difference, remolded soil is mostly adopted for preparing petroleum polluted soil samples in the current laboratory; the steps for preparing the petroleum polluted soil sample by remolding soil are approximately as follows:

(1) according to the operational requirements of 'geotechnical test method Standard' (GB/T50123-2019), crushing an undisturbed soil sample, then grinding, air-drying, sieving and measuring the water content.

(2) The water and oil contents required for the formulation test. A certain amount of water and petroleum are uniformly mixed with the soil sample, and the pollution intensity and the water content required by the test are configured.

(3) Pressing a soil sample by a pressure sampling machine: and (3) putting the scattered soil which is fully stirred by a certain mass into a mould, applying axial pressure to prepare a sample for forming, keeping the axial pressure unchanged and controlling the dry density.

The traditional method for preparing the sample mostly adopts manual sample preparation, and has the following problems:

(1) when evenly mixing a certain amount of water and oil with the soil sample, manual stirring is often adopted to traditional mode, because the problem that soil self viscosity and oil just are difficult to mutually dissolve mutually with water originally, in addition can't guarantee to add water, add oil and stir three operation and go on simultaneously, lead to the sample to be difficult to the misce bene, cause the sample to have great difference in the distribution of the water content and the oil content in each region after the shaping.

(2) The scattered soil of stirring before the system appearance, traditional mode often adopts the mode of manual shovel material to pack into scattered soil and presses the appearance container, and at this in-process, manual feeding is inevitable to cause certain loss to the scattered soil material of stirring, and the soil sample after the stirring often needs the manual work to carry to pressing appearance device department and just can press the appearance, and whole process is power consuming time, has the inconvenient problem of operation.

(3) The time that traditional manual system appearance process consumed is longer, even if adopt automatic pressure appearance ware, once only can prepare a sample, presses appearance inefficiency to when carrying out sample parameter measurement, the data that a sample was measured are inaccurate inadequately, need prepare two and more generally and refer to the contrast, so can cause the different and problem of pressing appearance process time overlength of same batch soil sample pressure appearance time sequence.
