Description

Technical Field

[0001] This invention relates to the field of soil archaeological site deterioration simulation test technology, and in particular to a small square sample support suitable for deterioration simulation tests. Background Technology

[0002] Earthen sites, as tangible evidence of human civilization's evolution, hold irreplaceable value in their protection and research for preserving historical and cultural heritage and revealing ancient social forms and traditional construction techniques. However, earthen sites are highly susceptible to erosion and damage from natural factors. Their vulnerability stems primarily from the dynamic interaction between material properties and their environment: the migration and crystallization of salts during wet-dry cycles; thermal stress induced by diurnal temperature variations leading to the development and expansion of surface cracks; wind and sand erosion causing surface morphology and deterioration of low-density areas; and precipitation infiltration resulting in clay mineral dissociation, gully flow marks, structural damage, and overall collapse. Sites exhibit differentiated degradation patterns in different climatic zones. Establishing a scientific research system for the interaction between environment and materials has become an urgent need for the current protection of earthen sites.

[0003] The degradation simulation experiment of earthen archaeological sites, utilizing cutting-edge experimental equipment and techniques, can accurately simulate the degradation process of earthen archaeological sites under different environmental conditions. This process provides crucial technical support and guidance for the restoration and reinforcement of earthen archaeological sites. During the experiment, researchers often use 5cm×5cm×5cm cubic samples as the observation objects.

[0004] Because the cubic samples need to be placed outdoors during the experiment, researchers need to precisely control the position and stability of the samples under various environmental conditions (including temperature, humidity, wind, rain, snow, etc.) to avoid errors caused by human operation and to prevent damage or abnormalities to the samples caused by external factors. However, there is currently no support for the samples, which makes it impossible to guarantee precise control of the position and stability of the samples. This is not conducive to conducting multiple experiments and comparative analyses, and it is impossible to accurately assess the deterioration of the earthen site under different environmental conditions. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a small square sample support suitable for degradation simulation tests that can reduce degradation test errors and maintain sample stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A support for small square samples suitable for degradation simulation tests includes a fixed base plate, a front panel, a support plate, an L-shaped baffle, side panels, and a rear panel. The fixed base plate has positioning structures on both sides for fixing its position. The front panel, rear panel, and two side panels are fixedly mounted on the fixed base plate, and the front panel, rear panel, and two side panels form a square structure. Multiple support plates are arranged inside the square structure. An L-shaped baffle is fixedly mounted between the rear panel and the adjacent support plate. The L-shaped baffle has a step, and a groove is provided in the middle of the support plate. The step is flush with the bottom wall of the groove, and the bottom wall of the groove is higher than the front panel, rear panel, and two side panels.

[0008] In a further technical solution, drainage holes are provided at the top of the side panel, front panel, and rear panel.

[0009] A further technical solution involves creating calibration cross holes on the side panels, front panel, and rear panel, with each hole located at its bottom center, upper left side, and upper right side.

[0010] A further technical solution is provided, wherein the fixed base plate is an acrylic plate of 70mm×90mm×5mm, the front panel is an acrylic plate of 60mm×20mm×5mm, the side panel is an acrylic plate of 70mm×20mm×5mm, and there are a total of three support plates, each 60mm long and 5mm thick, with a maximum height of 30mm. The bottom wall height of the groove is 25mm, and the groove is 50mm long, which can just hold a 5cm sample. The three support plates are spaced 13mm apart from each other and 10mm apart from the front and rear panels, which can support the sample well. The calibrated cross hole is 10mm long horizontally, 10mm long vertically, and 5mm deep.

[0011] In a further technical solution, the L-shaped baffle is located between the rear panel and the third support plate, with a length of 10mm, a thickness of 5mm, a maximum height of 50mm, a step height of 25mm, and an overall L-shape, which serves to stabilize the sample.

[0012] A further technical solution is that the positioning structure includes screw fixing holes on both sides of the fixed base plate, and the sample holder in the test environment is fixed by passing screws through the screw fixing holes.

[0013] As can be seen from the above, the small square sample support provided by this utility model, suitable for degradation simulation tests, has the following technical effects:

[0014] 1. The front panel, back panel, and two side panels are fixedly installed on the fixed base plate, and the front panel, back panel, and two side panels form a square structure. Multiple support plates are set inside the square structure to support the sample. Since the sample will be placed on an outdoor sample rack during the test, it needs to be supported to avoid external factors affecting the sample and causing it to be damaged or abnormal.

[0015] 2. Ensuring Sample Position and Reducing External Influence: The design of this small sample support significantly reduces sample displacement during the test. Due to the inherent characteristics of soil materials, their structure is relatively loose and easily affected by external factors, leading to displacement. This support, through its stable structure and precise positioning mechanism, ensures that the sample maintains a relatively fixed position during the test, thereby improving the accuracy and reliability of the test results.

[0016] 3. Provide a benchmark for comparison: In simulation experiments of the deterioration of earthen sites, it is often necessary to compare the deterioration at different stages. By setting clear marks on the supports, researchers can easily identify different samples and conduct accurate comparisons and analyses.

[0017] 4. Preventing rainwater backflow: During the experiment, rainwater seeps back through the holding platform to the bottom of the sample, increasing the amount of rainwater absorbed. The support's elevated and drainage functions effectively prevent rainwater backflow, protecting the sample from interference and reducing experimental errors.

[0018] 5. Prevents samples from being blown over or moved by strong winds: When conducting tests outdoors or in simulated environments, strong winds may interfere with the samples. This support features an L-shaped baffle design to resist wind, ensuring the stability and safety of the samples even in harsh weather conditions.

[0019] 6. Facilitates observation and recording: Its design takes into account the observation needs of researchers, allowing them to observe and record samples from different angles. At the same time, the support itself is flexible and can be adjusted according to experimental requirements, improving the efficiency and convenience of the experiment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Example, refer to Figure 1 — Figure 4 A small square sample support suitable for degradation simulation tests includes a fixed base plate 1, a front panel 2, a support plate 4, an L-shaped baffle 5, side panels 7, and a rear panel 9. Positioning structures for fixing the position are respectively provided on both sides of the fixed base plate 1. The front panel 2, rear panel 9, and two side panels 7 are fixedly mounted on the fixed base plate 1, forming a square structure. Multiple support plates 4 are arranged inside the square structure. An L-shaped baffle 5 is fixedly mounted between the rear panel 9 and the adjacent support plate 4. The L-shaped baffle 5 has a step 11. A groove 10 is provided in the middle of the support plate 4. The step 11 is flush with the bottom wall of the groove 10, and the bottom wall of the groove 10 is higher than the front panel 2, rear panel 9, and two side panels 7.

[0028] In use, the sample support is placed on the sample holder and fixed by the positioning structure. Multiple sample supports can be set. A cube-shaped soil sample is placed on the sample support, with the bottom of the sample located inside the groove 10. The step 11 also provides support for the sample. Because northwest winds are common in the northwest region, the L-shaped baffle 5 is located in the southeast or south direction of the sample to prevent it from falling. At the same time, the support essentially elevates the sample, preventing rainwater from eroding the bottom of the sample and ensuring that the sample can have normal contact with the environment without being damaged or abnormal. The front panel 2, the back panel 9, and the two side panels 7 are bonded together with epoxy resin adhesive. The L-shaped baffle 5 is also bonded to the support plate 4. (Before this sample support, the sample was placed directly on the sample holder, which caused water to accumulate at the bottom of the sample and become damp, leading to sample damage or abnormalities.)

[0029] The top of the side panel 7, the front panel 2, and the rear panel 9 are all provided with drainage holes 3. The drainage holes 3 are used to drain water from inside the square structure to prevent excessive water accumulation and to prevent water accumulation at the bottom from causing the test sample to absorb water and disintegrate. The drainage hole (3) is 5mm high, 3mm wide, and 5mm deep.

[0030] A calibration crosshole 6 is provided on the side panel 7, the front panel 2, and the rear panel 9, specifically at the bottom center, upper left side, and upper right side of each panel. This is for positioning assistance during fitting analysis, and is necessary when positioning using software after taking photographs.

[0031] The fixed base plate 1 is a 70mm×90mm×5mm acrylic sheet, the front panel 2 is a 60mm×20mm×5mm acrylic sheet, and the side panel 7 is a 70mm×20mm×5mm acrylic sheet. There are three support plates 4, each 60mm long and 5mm thick, with a maximum height of 30mm. The bottom wall height of the groove is 25mm, and the groove length is 50mm, which can just hold a 5cm sample. The three support plates 4 are spaced 13mm apart from each other and 10mm apart from the front panel 2 and the rear panel 9, providing good sample support. The calibrated cross holes 6 are 10mm long horizontally, 10mm long vertically, and 5mm deep. The three support plates provide good sample support, and the grooves are used to hold the sample in place, preventing displacement.

[0032] The L-shaped baffle 5 is located between the rear panel 9 and the third support plate 4. It is 10mm long, 5mm thick, 50mm high at its highest point, and 25mm high at the step. It is L-shaped in shape and plays a role in stabilizing the sample and preventing it from tipping over.

[0033] The positioning structure includes screw fixing holes 8 on both sides of the fixed base plate 1. By passing screws through the screw fixing holes 8, the support is fixed to the sample holding rack in the test environment, thus achieving overall fixation of the support.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
