Abstract
The invention relates to an operation method of preparing transparent soil under a vacuum situation. The operation method includes following steps: (a) placing transparent solid particles and a pore solution, which have been preset and are in certain mass, into two containers respectively; (b) opening the door on a vacuum glove box, and placing the two containers respectively filled with the transparent solid particles and the pore solution into the vacuum glove box, closing the door and an air inlet, opening a vacuumizing switch to vacuumize the vacuum glove box through an air exhaust; (c) when the vacuum degree in the vacuum glove box reaches requirement, maintaining the vacuum degree in the box and completely or partially pouring the transparent solid particles into the container filled with the pore solution in a manual manner with butyl rubber gloves; and (d) closing the vacuumizing switch and opening the air inlet to recover a normal atmosphere pressure in the vacuum glove box to complete preparation of the transparent soil. The transparent soil avoid invasion of bubbles during the preparation process completely and fundamentally, thereby ensuring the transparency of the transparent soil.
Description
Technical field
The present invention relates to a kind of method of operating preparing transparent soil, the pore solution particularly utilizing glutinousness little under a kind of vacuum state prepares the method for operating of transparent soil.
Background technology
In Geotechnical Engineering model test, observe and measure the stress deformation of the soil body, usually need to be implanted into various instrument at the soil body, measure the distortion of soil, especially measure the internal modification of the soil body under various stress condition, difficulty is larger.But along with the development of modeling techniques, a kind of non-intervention type geotechnical model technology that utilize transparent soil, that can measure inside soil body continuous modification is arisen at the historic moment.Just can observe without the need to implanting apparatus in this technology and calculate the deformation displacement field of the soil body, its key is transparent soil.Therefore, how to ensure that the transparency of transparent soil is a vital problem.At present, the mode that the method preparing transparent soil is mainly manually sprinkled into is carried out, this method preparation speed is slow, efficiency is lower, in any case and in process for preparation operate, all cannot avoid being mixed into or invading a large amount of air bubbles in transparent soil, therefore had a strong impact on the transparency of transparent soil, thus the usability in later stage is caused to decline.At present, the main air extractor that adopts to be bled process to the transparent soil configured, but the method only can siphon away the more shallow bubble in transparent soil model middle and upper part, and for invading darker bubble, then effect is little.
Therefore, need the method for operating of seeking the transparent soil of preparation that a kind of bubble-free invades at present badly and seem very important.
Summary of the invention
Object of the present invention overcomes above defect exactly, prepares the method for operating of transparent soil under providing a kind of vacuum state.The object of the invention is to be achieved through the following technical solutions:
Prepare a method of operating for transparent soil under vacuum state, comprise the following steps:
Step one, the clear solid granules of the same volume set and pore solution are placed in two containers respectively;
Step 2, open the chamber door of vacuum glove box, the container filling clear solid granules and pore solution is respectively put into vacuum glove box, closes chamber door;
Step 3, closedown air intake opening, opened vacuum switch, vacuumized by bleeding point to vacuum glove box;
Step 4, after the vacuum tightness in vacuum glove box exceedes-95kPa, maintain the vacuum tightness in case, manually all or part of for clear solid granules pouring into is filled in the container of pore solution by butyl rubber gloves;
Step 5, closedown vacuum switch, open air intake opening switch, recover the normal atmosphere pressure in vacuum glove box, open chamber door, take out the transparent soil model prepared.
As preferably, in step one: the volume shared in container of clear solid granules and pore solution is no more than the half of overall vessel volume.
As preferably, in step 4: pour in the process of pore solution the pore solution that do not have at clear solid granules into and spill outside container.
As preferably, in step 2: vacuum glove box is transparent, has visuality.
The invention has the beneficial effects as follows:
The transparent soil that the present invention prepares be bubble-free invade, completely saturated, overcome the defect of the bubble intrusion effect transparency in the transparent indigenous method of tradition preparation.
The method of the transparent soil of preparation provided by the present invention saves the preparation time greatly, overcomes classic method process for preparation overlength consuming time, defect that efficiency is lower.
The method of the transparent soil of preparation provided by the present invention, in the process for preparation of transparent soil, can not cause the waste of particulate material or liquid, its consumption reaches completely controlled state, overcomes the phenomenon of waste of material in the transparent indigenous method of tradition preparation.
