Problems solved by technology

However, the existing soil sample storage devices have poor sealing performance, which can easily cause the true moisture content of the undisturbed soil to be low, and cannot effectively protect soil samples that are not easy to form and collapse (such as soil with high moisture content and soft soil quality). There are many models and specifications. In order to effectively match the size of the device, the soil sample size is high, and the protection of irregular soil samples is poor. Therefore, it is necessary for us to develop an undisturbed soil sample with high sealing performance and good protection performance. Sealing means

Embodiment 1

[0034] This embodiment discloses an undisturbed soil sample sealing device based on a wax sealing method, which includes a soil sample holder, a circular hollow partition 4, an inner tube sleeve 5 and a long-necked funnel 10.

[0035] See figure 1 The soil sample placing device includes a top cover 1, a bottom cover 2, an outer layer of the soil sample placing sleeve 6 and an inner layer 7 of the soil sample placing sleeve, the outer layer 6 of the soil sample placing sleeve and the inner layer of the soil sample placing sleeve 7 are cylinders with open ends and a hollow inside. The inner layer 7 of the soil sample placing sleeve is placed vertically, and the outer layer 6 of the soil sample placing sleeve is sleeved on the outer surface of the inner layer 7 of the soil sample placing sleeve.

[0036] Wherein, the outer layer 6 of the soil sample placement sleeve is made of a soft foam material with light weight and excellent cushioning effect, which can protect the sample from dama...

Embodiment 2

[0046] This embodiment discloses a sealing method of an undisturbed soil sample sealing device based on a wax sealing method. Based on the sealing device described in Example 1, the method includes the following steps:

[0047] 1) Turn on the paraffin pellet hot melter, heat the paraffin pellets, and install the bottom cover 2 to the lower end of the inner layer 7 of the soil sample placing sleeve and tighten it. Among them, paraffin wax particles melt at 47℃~64℃, and the density is about 0.9g / cm 3 , It has good physical properties such as stability and thermal properties, non-toxic and will not harm the health of test personnel, low melting point, easy to melt under heat, strong fluidity in liquid state, and insoluble in water. The main function of the paraffin particle hot melter is to heat the paraffin particles so that the sealing particles are heated from solid to liquid, and the sealing liquid is injected into the soil sample holder to seal the sample.

[0048] 2) Determine t...

Embodiment 3

[0061] This embodiment discloses an undisturbed soil sample sealing device based on a wax sealing method, which includes a soil sample holder, a circular hollow partition 4, an inner tube sleeve 5 and a long-necked funnel 10.

[0062] See figure 1 The soil sample placing device includes a top cover 1, a bottom cover 2, an outer layer of the soil sample placing sleeve 6 and an inner layer 7 of the soil sample placing sleeve, the outer layer 6 of the soil sample placing sleeve and the inner layer of the soil sample placing sleeve 7 are cylinders with open ends and a hollow inside. The inner layer 7 of the soil sample placing sleeve is placed vertically, and the outer layer 6 of the soil sample placing sleeve is glued on the outer surface of the inner layer 7 of the soil sample placing sleeve.

[0063] The top cover 1 and the bottom cover 2 are both provided with internal threads, the upper end of the inner layer 7 of the soil sample placement sleeve is provided with external threads t...

Abstract

The invention discloses an undisturbed soil sample sealing device based on a wax sealing method and a sealing method thereof, and relates to the technical field of soil sample collection. The undisturbed soil sample sealing device based on the wax sealing method comprises a soil sample placer, circular hollow partition plates, inner pipe sleeves and a long-neck funnel, wherein the soil sample placer is composed of two layers of materials, a plurality of inner pipe sleeves and a plurality of circular hollow partition plates are arranged in the soil sample placer, an undisturbed soil sample is placed in the inner pipe sleeves, liquid paraffin is injected into the soil sample placer through the long-neck funnel, and the undisturbed soil sample is poured and sealed. The undisturbed soil samplesealing device has the advantages of being higher in sealing performance on irregular soil samples, higher in protectiveness on soil samples difficult to form, tighter in fitting with the inner wallof the sealing device and the like, and the problems that an existing soil sample sealing device is poor in sealing performance, low in protection performance, high in requirement for the size of thesoil samples, single in size of the soil samples suitable for each specification and the like are solved.

Description

Technical field [0001] The invention relates to the technical field of soil sample collection, in particular to an undisturbed soil sample sealing device based on a wax sealing method and a sealing method thereof. Background technique [0002] In geological engineering and geotechnical engineering, the physical and mechanical properties of soil are the basis of engineering geological evaluation and an important parameter of geotechnical engineering design and construction. Because some experimental instruments cannot be used for field measurement, the soil samples must be brought back to the laboratory for experiments . Therefore, how to bring the undisturbed soil in the field back to the laboratory efficiently and safely has become the key to measuring the accuracy of the physical and mechanical properties of the soil. However, the existing soil sample preservation device has poor sealing performance, which may cause the actual water content of the undisturbed soil to be low, a...
