Description

Technical Field

[0001] The present application relates to the technical field of engineering survey sampling, and in particular to a soil sample box and a soil sample turnover management method. Background Art

[0002] At present, the original soil samples taken from drilling holes in engineering surveys are generally cylindrical and packaged in iron tubes. After each geotechnical sample is sealed, a paper label is filled on the surface of each iron tube with relevant information of the soil sample. When transporting geotechnical samples, special soil sample boxes are used for packaging, and soft cushioning materials are filled between the samples. According to the "Standard for Geotechnical Test Methods" GB / T50123, after the soil samples are sent to the test unit for acceptance and registration, the soil samples shall be properly stored in order. The original soil samples and disturbed soil samples that maintain the natural moisture content shall be placed in a cool place to prevent disturbance and water evaporation as much as possible. The time from the date of sampling to the start of the test should not exceed 3 weeks.

[0003] At present, in engineering survey work, after drilling and obtaining rock and soil samples in the field, there are a series of turnover links from packaging, labeling, transportation, handling, indoor storage to sample placement and preparation before testing, such as the difficulty in maintaining the original state of rock and soil samples, poor sample quality, repeated and cumbersome sample turnover process, and long storage time affecting the accuracy of test data. Specifically, there are at least the following problems:

[0004] During engineering surveys, each rock and soil sample taken from a drilling hole needs to be sealed in a tin tube and then filled with a paper label. This operation is inefficient and can easily cause unclear writing during transportation and storage. Paper labels, as a medium for circulating rock and soil sample information, are also prone to damage or loss during the circulation process.

[0005] In the existing soil sample box packaging and transportation process, spring parts are mainly used for cushioning to prevent the soil samples from being disturbed during transportation. However, if the spring length is set to be short, the cushioning effect is not obvious, and if the spring length is set to be too long, the use of the space in the box is limited.

[0006] In the existing turnover management of rock and soil samples, there is a lack of monitoring measures for the storage status and storage time of rock and soil samples. The test data is distorted due to changes in sample quality caused by too low or too high temperature and humidity, or because the samples are stored for too long after being collected in the field.

[0007] At present, after the rock and soil samples collected in the field are transported to the laboratory, laboratory personnel need to spend a lot of time selecting and placing them in order for storage. Before conducting the test, the rock and soil samples need to be placed one by one on the test bench in order and numbered to make preparations before the test, and the process efficiency is low.

The buffer mechanism 4 is arranged inside the box shell 3 and / or the base platform 1 to protect the rock and soil samples.

[0090] After the rock and soil samples collected from the field during the engineering survey are packaged, each packaged rock and soil sample is placed in a tray 2 on the base platform 1 in the cavity. During transportation, the rock and soil samples are damped and buffered in the horizontal and vertical directions by the buffer mechanism 4 arranged inside the box shell 3 and on the base platform 1, respectively, to reduce the disturbance of the rock and soil samples and improve the shockproof, seismic isolation and buffering effects. After the rock and soil samples are transported to the designated location through the soil sample box, the base platform 1 is separated from the box shell 3 by the connecting mechanism 5 between the edge of the base platform 1 and the box shell 3, leaving only the base platform 1 and the tray 2 installed on the upper surface of the base platform 1. There is no need to spend time selecting and taking out the rock and soil samples, which makes the work process simpler and smoother and improves the test efficiency of the rock and soil samples.

[0091] In some embodiments, placement marks are provided on the surface of the base platform 1, and the placement order of the rock and soil samples in the soil sample box is guided by the placement marks.

[0092] refer to Figure 3 As an optional embodiment, each tray 2 includes a tray body 21, an elastic friction ring 22 and a fixing ring 23. The tray body 21 is fixed to the upper surface of the base platform 1, and the tray body 21 is provided with a bearing groove 211 for placing the rock and soil sample in the bearing groove 211. The elastic friction ring 22 is installed in the bearing groove 211, and the inner ring of the elastic friction ring 22 acts on the surface of the rock and soil sample to limit the position of the rock and soil sample. The fixing ring 23 is pressed on the top of the elastic friction ring 22, and is used to limit the elastic friction ring 22 and press it between the fixing ring 23 and the tray body 21.

[0093] In some embodiments, the elastic friction ring 22 is made of rubber material.

[0094] The rock and soil sample is accommodated and positioned by the bearing groove 211, and the inner wall of the tray body 21 may be provided with a ring groove for embedding the elastic friction ring 22 so that the elastic friction ring 22 is installed in the bearing groove 211. The inner wall of the tray body 21 may also be provided with an internal thread, and the fixing ring 23 is screwed with the inner wall of the tray body 21 through the thread, so that the elastic friction ring 22 is pressed against the tray body 21. The elastic friction ring 22 acts on the surface of the rock and soil sample, and fixes the rock and soil sample through the elastic force and friction force of the elastic friction ring 22.

[0095] refer to Figure 4 and Figure 6 As an optional embodiment, a driving movement cavity is provided in the base platform 1, one end of which is connected to the outside of the base platform 1, and the box shell 3 is provided with a bayonet corresponding to the position of the driving movement cavity, and the connecting mechanism 5 includes a driving component 51 and a clamping member 52. Among them, the driving component 51 is located in the driving movement cavity. One end of the clamping member 52 is connected to the driving component 51, and the other end moves in a direction close to or away from the bayonet under the drive of the driving component 51.

[0096] As an optional embodiment, the driving assembly 51 includes a driving gear 511, a connecting rod 512 and a connecting knob 513.

The limiting flange 522 is connected to the engaging member body 521 as a whole, and the surface of the limiting flange 522 matches the inner wall of the driving moving cavity.

[0098] When the connection knob 513 is turned, the connection rod 512 and the driving gear 511 rotate synchronously with the connection knob 513, and the driving gear 511 meshes with the engaging member 52 through the meshing teeth 523 of the engaging member 52. The engaging member 52 is driven to move by the rotation of the driving gear 511. When one end of the engaging member 52 extends into the bayonet of the box shell 3 driven by the driving gear 511, the base platform 1 is connected to the box shell 3. When one end of the engaging member 52 is separated from the bayonet of the box shell 3 driven by the driving gear 511, the base platform 1 is separated from the box shell 3, so as to facilitate the placement or use of the rock and soil sample. The limiting flange 522 is used to limit the engaging member 52 when it moves along the driving moving cavity.

[0099] refer to Figure 6 As an optional embodiment, the buffer mechanism 4 includes a buffer support 41, and the buffer support 41 includes a shock absorbing core 411, a sealing plate 412 and a protective layer 413. The shock absorbing core 411 is located between the base platform 1 and the tray 2, and the shock absorbing core 411 includes an elastic sheet 4112 and a metal sheet 4111, and the metal sheet 4111 and the elastic sheet 4112 are stacked, and the metal sheet 4111 and the elastic sheet 4112 are interlaced with each other. The sealing plate 412 is arranged at the upper and lower ends of the shock absorbing core 411, and is connected to the base platform 1 and the tray 2. The protective layer 413 is coated on the surface of the shock absorbing core 411, and is used to protect the shock absorbing core 411.

[0100] The buffer support 41 vertically damps and cushions the rock and soil samples in the tray 2. The metal sheet 4111 and the elastic sheet 4112 are stacked to form a shock-absorbing core 411, so as to reduce the space occupied by the buffer support 41 in the soil sample box while satisfying the buffering effect, thereby improving the utilization rate of the space in the cavity of the soil sample box.

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

[0102] refer to Figure 7 As an optional embodiment, the buffer mechanism 4 includes a buffer frame 42. The buffer frame 42 includes a slide bar 421, a first slide frame 422, a second slide frame 423 and a stop block 424. The slide bar 421 is fixed to the inner wall of the box shell 3. One end of the first slide frame 422 is connected to the box shell 3, and the other end of the first slide frame 422 is slidably set on the slide bar 421. One end of the second slide frame 423 is connected to the box shell 3, and the other end of the second slide frame 423 is slidably set on the slide bar 421, so that it is close to or away from the first slide frame 422. The stop block 424 is fixed to the slide bar 421 and is located between the first slide frame 422 and the second slide frame 423.

[0103] The buffer rack 42 performs shock absorption and buffering on the rock and soil samples in the horizontal direction to reduce the disturbance of the rock and soil samples during transportation. After placing the rock and soil samples on the tray 2 and connecting the box shell 3 to the base platform 1, the first sliding rack 422 and the second sliding rack 423 are relatively moved along the slide bar 421, and the distance between the first sliding rack 422 and the second sliding rack 423 is reduced until the first sliding rack 422 and the second sliding rack 423 contact the limit block 424. At this time, the first sliding rack 422 and the second sliding rack 423 jointly clamp and fix the rock and soil samples. After the rock and soil samples are transported to the designated location, the first sliding rack 422 and the second sliding rack 423 are moved back to back along the slide bar 421, and the distance between the first sliding rack 422 and the second sliding rack 423 is increased and opened, and then separated from the rock and soil samples, and then the box shell 3 is separated from the base platform 1 and the box shell 3 is removed, and the rock and soil samples can be tested.

[0104] refer to Figure 8 As an optional embodiment, the first sliding frame 422 and the second sliding frame 423 each include a push rod 4201, a locking knob 4202 and a shock-absorbing locking portion 4203. The push rod 4201 is slidably connected to the sliding rod 421 through a sleeve 4204, and the push rod 4201 is provided with a connecting tube 4205. The locking knob 4202 is threadedly connected to the inner wall of the connecting tube 4205 and is located outside the box shell 3. The shock-absorbing locking portion 4203 is connected to the push rod 4201 and slides along the sliding rod 421 driven by the push rod 4201.

[0105] When the first sliding frame 422 and the second sliding frame 423 are driven to move along the sliding rod 421, the locking knob 4202 is rotated, and the locking knob 4202 is threadedly connected with the connecting tube 4205, thereby driving the connecting tube 4205 and the push rod 4201 to move. During the movement, since the sleeve 4204 is sleeved on the sliding rod 421, the moving direction of the push rod 4201 is limited, so that it moves back and forth along the direction of the sliding rod 421, avoiding the position misalignment of the shock-absorbing locking part 4203 and the rock and soil sample, and improving the effectiveness of clamping.

[0106] refer to Fig. 9 As an optional embodiment, the shock-absorbing locking part 4203 includes a shock-absorbing locking part body 4031, a clamping block 4032, and an elastic pad 4033. The shock-absorbing locking part body 4031 has a plurality of locking grooves 4034 that match the rock sample, and the locking grooves 4034 are semicircular. The clamping block 4032 is fixed to the inner wall of the locking groove 4034, and a clamping groove 4035 is formed between two adjacent clamping blocks 4032. The elastic pad 4033 is fixed in the locking groove 4034, and is clamped with the shock-absorbing locking part body 4031 through the clamping block 4032 and the clamping groove 4035.

[0107] When the buffer frame 42 fixes the rock and soil sample in the horizontal direction, the rock and soil sample is confined in the locking groove 4034, and the elastic pad 4033 provides buffering for the rock and soil sample in the horizontal direction.

One end of the buckle body 33 is connected to the box cover 32, and the other end of the buckle body 33 is buckled with the box body 31, which is used to connect the box cover 32 to the box body 31. The handle 34 is installed on at least one of the box body 31 and the box cover 32, and is used to lift the soil sample box. For example, the handle 34 is fixed to both sides of the box body 31, or the handle 34 is fixed to the top of the box cover 32. The box cover 32 is detachably connected to the box body 31 through the buckle body 33, and is used to open the box cover 32 to quickly confirm the status of the rock and soil samples in the box when there is no need to take out the rock and soil samples.

[0110] refer to Fig.10As an optional implementation, the soil sample box also includes a storage management module 6, which is arranged on the base platform 1 or the box shell 3, and is used to monitor and record the environmental status in the cavity and the status of the rock and soil samples.

The storage time of the rock and soil samples after being taken out from the engineering survey borehole is recorded by the timer in the storage management module 6, the temperature in the management box is recorded by the temperature sensor, the humidity in the management box is recorded by the humidity sensor, and the storage time, temperature and humidity sensed and recorded by the timer, temperature sensor and humidity sensor are displayed on the display screen. Based on the storage time, temperature and humidity data obtained, the storage time of the rock and soil samples is managed to ensure that the soil samples complete the test within the specified time limit, and the storage environment of the rock and soil samples is adjusted by recording and managing the temperature and humidity information in the soil sample box to make it suitable for the storage of rock and soil samples.

[0112] refer to Figure 1 and Fig.10 As an optional implementation, the soil sample box also includes an electronic tag 7, which is set on at least one of the base platform 1 and the box shell 3, and is used to enter, modify or read information corresponding to the rock and soil sample.

[0113] The information of the rock and soil samples is managed electronically through the electronic tag 7. Each electronic tag 7 has a unique serial number and corresponds to the rock and soil sample one by one, which facilitates the circulation and identification of the rock and soil samples in subsequent different test links, avoids the phenomenon of unclear handwriting, damage or loss in the turnover link, and reduces the repeated use of paper identification numbers or repeated sorting processes in the traditional test process. In addition, the electronic tag 7 can be repeatedly modified and entered after all tests on the rock and soil samples are completed.

[0114] For example, a corresponding electronic tag 7 is provided at each tray 2 for recording the information of the rock and soil samples placed in each tray 2, and the rock and soil sample information includes sampling number, sampling depth, field naming of the sample, etc. The electronic tag 7 can also be fixed on the surface of the box shell 3, and the electronic tag 7 fixed on the surface of the box shell 3 is used to record the whole box project information of the soil sample box, and the project information includes project name, sampling location, sampling time, commissioning unit, etc.

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

[0116] In step S101, the rock and soil samples obtained by drilling in the engineering survey are packaged in iron tubes, and each packaged rock and soil sample is placed on a tray 2 at a corresponding position.

[0117] In step S102, after all required rock and soil samples are placed in the tray 2 in sequence, the box shell 3 is connected and fixed to the base platform 1 to achieve box sealing, so that the packaged rock and soil samples are sealed in the cavity.

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

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

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

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

[0122] In step S106, the base platform 1 is separated from the box shell 3 through the connecting mechanism 5. During the separation process of the base platform 1 and the box shell 3, it is necessary to first rotate the locking knob 4202 to separate the buffer rack 42 in the soil sample box to be tested from the rock and soil sample, so as to remove the box shell 3 and leave only the base platform 1 and the rock and soil sample to test the rock and soil sample.

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

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

[0125] For example, after placing the packaged rock and soil samples on the tray 2, the handheld reader / writer terminal corresponding to the electronic tag 7 can be used to scan it, and the number, sampling depth, field naming and other information of the rock and soil samples in the tray 2 at the position corresponding to the electronic tag 7 can be entered.

[0126] Or after all the rock and soil samples are placed in the soil sample box and the base platform 1 is connected and sealed with the box shell 3, the electronic tag 7 on the surface of the box shell 3 is scanned using a handheld reader / writer terminal, and the engineering information corresponding to the entire box of the soil sample box, such as the name of the project, sampling location, sampling time, and the entrusting unit, is entered into the electronic tag 7 on the surface of the box shell 3.

[0127] In step S108, when the rock and soil samples are tested, the electronic tags 7 at the corresponding positions are read and registered. That is, when information needs to be read, the corresponding electronic tags 7 are scanned in turn by the handheld reader / writer terminal to read the information recorded therein.

[0128] In some embodiments, when conducting experiments, a handheld terminal can also be used to read the information of the electronic tag 7 corresponding to each rock and soil sample, and copy the information to the container electronic tag of the test container corresponding to the rock and soil sample in the subsequent test link, so as to prepare for the circulation of rock and soil samples 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 time of the soil sample in the soil sample box is recorded.

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

[0132] For example, in days, when the recorded storage time exceeds 20 days, or when the environmental conditions do not meet the temperature of about 20 degrees Celsius, or the humidity does not meet the 50%-60% range, the warning light will be turned on to issue a warning, thereby reminding the user to conduct the test as soon as possible or adjust the environmental conditions of the soil sample box in time to avoid water loss or excessive moisture absorption of the rock and soil samples.

[0133] The soil sample turnover management method using the above-mentioned soil sample box provided by this application provides a safe, complete and convenient process for packaging, labeling, boxing and transportation, monitoring of rock and soil samples after they are collected in the field, to indoor registration and storage, and preparation of rock and soil samples before testing. It ensures that the rock and soil samples can continue to be close to their original state in the formation from the time they are drilled in the field to the time they are tested indoors, thereby ensuring the accuracy of the test data, and also improving the work efficiency of the rock and soil samples during the turnover process.
