Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of prospecting and detection, in particular to a new type of hand-pushed soil sample preservation device. Background Art
[0002] Soil is a product of nature, and its formation process and material composition are extremely complex. All kinds of projects largely depend on whether the soil can provide sufficient bearing capacity. Therefore, sampling is an essential process before indoor tests in geotechnical engineering, aiming to obtain test samples representing the sampled soil (rock) layer. However, the transportation and preservation after sampling will disturb the soil sample to varying degrees. Since the particle structure of natural clay is damaged during remolding and cannot be restored later, let alone replicated indoors, this requires us to minimize the disturbance of the soil sample as much as possible and maintain the original structure and natural humidity of the soil as much as possible to reduce the impact of test errors on the project quality. How to avoid the disturbance brought during the transportation of soil samples is a research direction.
[0003] Currently, the commonly used methods for preserving soil samples are generally simple plastic boxes or simple foam boxes, which have little buffering effect on the vibration generated during the transportation of soil samples. Secondly, they cannot effectively avoid the influence of temperature, and it is extremely easy to cause errors in indicators such as the water content of the soil sample. In addition, how to avoid the disturbance brought during the transportation of soil samples and effectively seal to prevent the water content from changing due to temperature changes is also a technical problem to be solved urgently. Summary of the Invention
[0004] The purpose of the utility model is to provide a new type of hand-pushed soil sample preservation device according to the deficiencies of the above-mentioned existing technologies. Through the structural design of the outer box and the inner storage box, and in cooperation with relevant functional structures, the quality of the soil sample is effectively improved, and the accuracy of indoor tests in geotechnical engineering is further improved.
[0005] The purpose of the utility model is achieved by the following technical solutions:
[0006] A new type of hand-pushed soil sample preservation device, characterized in that: it includes an outer box and an inner storage box, the inner storage box is embedded inside the outer box, the inner storage box is provided with mounting holes, and storage cylinders for preserving soil samples are placed in the mounting holes. A limiting plate is arranged above the storage cylinders, a rotator is arranged above the outer box, the rotator is connected with a telescopic card slot, and the rotator drives the telescopic card slot to be lowered and tightly combined with the limiting plate where the storage cylinders are placed.
[0007] A buffer layer is arranged around the mounting holes, a heat insulation layer is fixedly arranged inside the inner storage box, and the heat insulation layer is connected with the buffer layer.
[0008] Sliding rails are arranged on the inner wall of the outer box, and the inner storage box is in sliding fit connection with the sliding rails.
[0009] An opening and closing card slot for placing labels is provided on the storage cylinder.
[0010] A connecting rod is provided on one side of the outer box, and a pull rod is provided on one side of the inner storage box. The pull rod is located on the other side of the connecting rod.
[0011] Universal wheels are provided at the bottom of the outer box.
[0012] The advantages of the present utility model are as follows:
[0013] 1) It solves the problems of inconvenient transportation and large workload of sampling personnel caused by traditional soil sample preservation devices. By setting universal wheels, the transportation is made convenient and the workload of sampling personnel is reduced.
[0014] 2) It solves the problem that the traditional soil sample preservation device is jolted during transportation and the soil sample is disturbed. Through the buffer layer and fixed setting, the disturbance of the soil sample during transportation is reduced.
[0015] 3) It solves the problem that the traditional soil sample preservation device may have poor sealing, which affects the original characteristics of the soil sample, effectively reduces the influence of temperature change on the water content of the soil sample, and ensures the accuracy of the experimental results.

[0022] Embodiment: As Figures 1 to 4As shown in the figure, the new hand-pushed soil sample preservation device in this embodiment includes the following usage method:
[0023] 1) The sampling personnel control the connecting rod 5 to move the hand-pushed soil sample preservation device of this embodiment to the sampling site.
[0024] 2) The sampling personnel put the soil sample into the storage cylinder 14, accurately fill in the sampling label and put it into the openable and closable card slot 15 and close the card slot, so that the soil sample can form a one-to-one correspondence with the sampling label.
[0025] 3) Then, the inner storage box 2 is controlled to extend out of the outer box 1 along the slide rail 7 through the pull rod 6, and the storage cylinder 14 is put into the installation hole 9 of the inner storage box 2. A buffer layer 3 is arranged around the installation hole 9, and the buffer layer 3 is mainly made of EPE, which is convenient for buffering the disturbance to the soil body during the transportation of the soil sample. An insulating layer 4 is fixedly arranged inside the inner storage box 2, and the insulating layer 4 is connected to the buffer layer 3. The insulating layer 4 can be made of polystyrene foam plastic, which is convenient for isolating the temperature inside the box from the external temperature.
[0026] 4) After all the storage cylinders 14 are completely put in one by one, the inner storage box 2 is then closed into the outer box 1 through the slide rail 7, and the rotator 10 above the outer box 1 is controlled to lower the telescopic card slot 11 arranged on the outer box 1 to be tightly combined with the limiting plate 8 where the storage cylinder 14 is placed, so as to effectively limit the storage cylinder 14.
[0027] 5) Finally, the hand-pushed soil sample preservation device is transported to the laboratory for testing.
[0028] The platform vehicle in this embodiment is used for application tests. The proposed site is located in the artificial reclaimed offshore island in the southern sea area of Hailongkou Bay, Longkou City, Shandong Province, near the boundary between Longkou City and Zhaoyuan City. It is a benchmark project for the transformation of new and old driving forces in Shandong Province and a super-large engineering construction project in the domestic petrochemical industry at present. According to the site geological conditions and the actual situation on site, technical disclosure is carried out. When sampling at variable layers and the soil layer thickness is greater than 5 meters, another soil sample is taken every 5m.
