Description

TECHNICAL FIELD

[0001] The present application relates to the field of engineering investigation sampling technology, and particularly relates to a soil sample box. BACKGROUND

[0002] At present, the undisturbed soil sample taken by drilling in engineering investigation is generally in cylindrical shape and is packaged with an iron cylinder. After each geotechnical sample is sealed, a paper label is attached to the surface of each iron cylinder, and the paper label contains the information of the soil sample. When transporting the geotechnical sample, a special soil sample box is used for packaging, and the samples are filled with soft cushioning material. According to the Standard for Soil Test Methods (GB / T 50123), after the soil sample is delivered to the test unit for acceptance and registration, the soil sample is properly stored in order. The undisturbed soil sample and the disturbed soil sample maintaining the natural water content should be placed in a cool place to prevent disturbance and water evaporation as much as possible. The time from the sampling date to the start of the test should not exceed 3 weeks.

[0003] At present, in the engineering investigation work, after the geotechnical sample is drilled in the field, there are problems such as difficulty in maintaining the original state of the geotechnical sample, poor sample quality, repeated and complicated sample turnover process, and long storage time affecting the accuracy of test data in a series of turnover links such as packaging, labeling, transportation, handling, indoor storage, and sample placement preparation before testing. Specifically, there are at least the following problems:

[0004] After each geotechnical sample taken by drilling in engineering investigation is packaged with an iron cylinder, a paper label needs to be attached, which is low in operation efficiency, and the handwriting is prone to be unclear during transportation and storage. The paper label as the turnover medium of the information of the geotechnical sample is also prone to damage or loss in the turnover link.

[0005] In the existing soil sample box packaging and transportation process, the spring piece is mainly used for buffering to prevent the disturbance of the soil sample during transportation. However, if the length of the spring piece is short, the buffering effect is not obvious, and if the length of the spring piece is too large, the space in the box is limited.

[0006] In the existing turnover management process of the geotechnical sample, there is a lack of monitoring measures for the storage state and storage time of the geotechnical sample. The sample quality is changed due to the excessively low or high temperature and humidity, or the test data is distorted due to the excessively long storage time of the sample taken in the field.

[0007] At present, after the geotechnical sample taken in the field is transported to the test room, the test room personnel need to spend a lot of time to select and store the sample in order. Before the test, the geotechnical sample needs to be placed on the test table in order and numbered, and the test preparation is completed. The process flow is low in efficiency.

[0099] Reference Figure 6 As an optional implementation, the buffering mechanism 4 comprises a buffering support 41, and the buffering support 41 comprises a damping core 411, a sealing plate 412 and a protective layer 413.

The protective layer 413 is coated on the surface of the damping core 411 and used for protecting the damping core 411.

[0100] The buffer support 41 buffers the geotechnical sample in the tray 2 in the vertical direction, and the damping core 411 is formed by laminating the metal sheet 4111 and the elastic sheet 4112, so as to reduce the space occupied by the buffer support 41 in the soil sample box and improve the utilization rate of the space in the cavity of the soil sample box while meeting the buffering effect.

[0101] In some embodiments, the elastic sheet 4112 and the protective layer 413 are rubber materials.

[0103] The buffer frame 42 buffers the geotechnical sample in the horizontal direction, so as to reduce the disturbance of the geotechnical sample during transportation. After the geotechnical sample is placed in the tray 2 and the box shell 3 is connected to the base platform 1, the first sliding frame 422 and the second sliding frame 423 are relatively moved along the sliding rod 421, the distance between the first sliding frame 422 and the second sliding frame 423 is reduced, and the first sliding frame 422 and the second sliding frame 423 are in contact with the limiting block 424. At this time, the first sliding frame 422 and the second sliding frame 423 jointly clamp and fix the geotechnical sample. After the geotechnical sample is transported to a designated position, the first sliding frame 422 and the second sliding frame 423 are moved away from each other along the sliding rod 421, the distance between the first sliding frame 422 and the second sliding frame 423 is increased to be opened, and then the box shell 3 is separated from the base platform 1, and the box shell 3 is taken away, so that the geotechnical sample can be tested.

For example, the handle 34 is fixed on both sides of the box body 31, or the handle 34 is fixed on the top of the box cover 32. The box cover 32 is detachably connected with the box body 31 through the buckle body 33, which is used to open the box cover 32 to quickly check the state of the rock-soil sample in the box when the rock-soil sample does not need to be taken out.

[0113] The information of the geotechnical sample can be managed electronically through the electronic tag 7. Each electronic tag 7 has a unique serial number and corresponds to the geotechnical sample one by one, which facilitates the identification of the geotechnical sample in the subsequent different test links, avoids the phenomenon of unclear, damaged or lost in the turnover link, reduces the repeated use of paper identification number or repeated sorting process in the traditional test process, and the electronic tag 7 can be repeatedly modified and input after all the tests of the geotechnical sample are completed.

[0114] For example, the corresponding electronic tag 7 is arranged at each tray 2, which is used to input the information of the geotechnical sample placed in each tray 2. The information of the geotechnical sample includes the sampling number, the sampling depth and the sample field name. The electronic tag 7 can also be fixed on the surface of the box shell 3, which is used to input the whole box engineering information of the soil sample box. The engineering information includes the engineering name, the sampling site, the sampling time, the entrusting unit and other information.

[0115] The application also provides a soil sample turnover management method using the above soil sample box, which comprises steps S101-S106.

[0116] In step S101, the rock-soil samples taken from the borehole in the engineering survey are packaged using the iron cylinder packaging engineering, and each packaged rock-soil sample is placed in the corresponding position of the tray 2.

[0117] In step S102, when the required rock-soil samples are sequentially placed in the tray 2, the box shell 3 is connected and fixed with the base platform 1 to realize the sealing of the box, so that the packaged rock-soil samples are sealed in the cavity.

[0118] In step S103, the buffering mechanism 4 acts on the rock-soil samples to fix or protect the rock-soil samples. The buffering support 41 in the buffering mechanism 4 buffers the rock-soil samples in the vertical direction, and the buffering frame 42 in the buffering mechanism 4 is tightened to buffer the rock-soil samples in the horizontal direction.

[0119] In step S104, the environment and the state of the rock-soil samples in the soil sample box are monitored.

[0120] The storage management module 6 is started by the monitoring switch, so that the timer in the storage management module 6 monitors and records the storage time of the rock-soil samples after being taken from the engineering survey borehole, and the temperature sensor and the humidity sensor monitor and record the temperature and humidity of the storage environment, respectively.

[0121] In step S105, the soil sample box is transported to the predetermined position, and the test sequence of the soil sample box is sorted according to the environment and the state of the rock-soil samples in the soil sample box.

[0122] In step S106, the base platform 1 is separated from the box shell 3 through the connecting mechanism 5. During the separation of the base platform 1 and the box shell 3, the buffering frame 42 in the soil sample box to be tested is first separated from the rock-soil samples by rotating the locking knob 4202, so that the box shell 3 is removed, and only the base platform 1 and the rock-soil samples are left, so as to test the rock-soil samples.

[0123] As an optional embodiment, the soil sample turnover management method using the above soil sample box further includes steps S107-S108.

[0124] In step S107, at least one of the information of each rock-soil sample, the whole-box engineering information of the soil sample box, and the result of the test is recorded in the electronic tag 7 at the corresponding position.

[0125] For example, after the packaged rock-soil samples are placed in the tray 2, the electronic tag 7 can be scanned by using the corresponding handheld read-write terminal, and the information of the rock-soil samples in the tray 2 at the corresponding position of the electronic tag 7, such as the sample number, the sampling depth, and the sample field name, is recorded.

[0126] Or after all the geotechnical samples are placed in the soil sample box, and the connection and sealing of the base platform 1 and the box shell 3 are completed, the hand-held read-write terminal is used to scan the electronic tag 7 on the surface of the box shell 3, and the engineering information of the corresponding whole-box engineering name, sampling site, sampling time, and entrusted unit of the soil sample box is input into the electronic tag 7 on the surface of the box shell 3.

[0127] In step S108, when the geotechnical sample is tested, the electronic tag 7 at the corresponding position is read and recorded. That is, when the information needs to be read, the corresponding electronic tag 7 is scanned by the hand-held read-write terminal in sequence to read the recorded information.

[0128] In some embodiments, the information of the electronic tag 7 corresponding to each geotechnical sample can also be read by the hand-held terminal when the test is carried out, and the information is copied to the container electronic tag of the test container corresponding to the geotechnical sample in the subsequent test link, so as to prepare for the circulation of the geotechnical sample in the subsequent test link.

[0129] As an optional implementation, step S105 includes sub-step S151 and sub-step S152.

[0130] In sub-step S151, the value of at least one of the temperature, humidity, and storage duration of the geotechnical sample in the soil sample box is recorded.

[0131] In sub-step S152, when the value is not within the preset value range, an alarm is issued.

[0132] For example, in units of days, when the recorded storage duration exceeds 20 days, or when the environmental state does not meet the temperature of about 20 degrees Celsius, or the humidity does not meet 50%-60%, the alarm light is turned on to issue an alarm. Thereby reminding the user to carry out the test as soon as possible or to adjust the environmental state of the soil sample box in time to avoid the loss of moisture or excessive moisture absorption of the geotechnical sample.

[0133] The soil sample circulation management method using the above soil sample box provided by the present application provides a safe, complete, and convenient process for packaging, labeling, transporting, and monitoring the geotechnical sample after it is taken from the field, to the registration and storage of the geotechnical sample in the laboratory, and the preparation of the geotechnical sample before the test, which ensures that the geotechnical sample can be kept close to the original state in the stratum from the time it is taken from the field to the time it is tested in the laboratory, thereby ensuring the accuracy of the test data, and also improving the work efficiency of the geotechnical sample in the circulation process.
