Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering, in particular to a sample detection device used for geotechnical engineering investigation. Background Art

[0002] Geotechnical engineering surveys are a crucial component of geotechnical engineering technology and the first foundational work undertaken in engineering construction. They involve identifying, analyzing, and evaluating the geological, environmental, and geotechnical conditions of a construction site, and compiling survey documents based on the requirements of the project. Their purpose is to investigate, research, analyze, and assess construction sites using testing methods and techniques, examining the geological conditions for constructing various structures and the impact of construction on the natural geological environment; to determine measures to ensure foundation strength and stability, and to prevent unacceptable deformation, when the foundation, substructure, and superstructure work together; to determine the bearing capacity of the foundation; and to provide the project address and geotechnical data required for foundation design and construction, as well as foundation reinforcement when necessary.

[0003] In geotechnical engineering surveys, it is necessary to test the extracted samples. After searching, the Chinese patent application number is: CN202222074325.7, which discloses a sample testing device for geotechnical engineering surveys. The device includes a base and a protective plate. The base is provided with a test table, a slide rail, and a gantry frame from the inside out, and a slider is installed above the slide rail. The protective plate is installed above the slider. The gantry frame is provided with an oil cylinder, and a push plate is installed below the oil cylinder. A guide rod is provided above the push plate, and a lubrication assembly for auxiliary lubrication is installed on the outer surface of the guide rod. The lubrication assembly includes a hollow guide sleeve, a screw cap, and a ball. The screw cap is installed on one side of the outer surface of the hollow guide sleeve. Compared with existing common sample testing devices, the sample testing device for geotechnical engineering surveys can prevent the splash of rock and soil during testing by pulling the protective plate. The protective plate slides along the slide rail through the slider, closing the two sets of protective plates.

[0004] The above technical solution still has a defect, that is, it lacks a collection function. After the sample is crushed, the debris will remain on the test table and need to be collected manually, which is inconvenient to use, reduces the detection efficiency, and increases the user's workload. Therefore, we need to propose a sample detection device for geotechnical engineering surveys. Utility Model Content

A bracket 2 is welded on the workbench 1, and the top plate 3 is welded to the upper end of the bracket 2. A door panel 10 is installed on one side wall of the workbench 1. A collection box 16 for collecting samples after the rock and soil are broken is placed at the inner bottom of the cavity 9. A support column 17 is arranged between the inner top and inner bottom of the cavity 9, and four groups of support columns 17 are symmetrically arranged in the cavity 9.

[0029] A crushing mechanism for crushing rock and soil samples; the crushing mechanism includes a hydraulic cylinder 4 and a pressing head 5. The hydraulic cylinder 4 is fixedly installed at the center of the top of the top plate 3. The hydraulic rod of the hydraulic cylinder 4 penetrates through the top plate 3 and extends to the lower side of the top plate 3. The pressing head 5 is fixedly connected to the end of the hydraulic rod of the hydraulic cylinder 4;

[0030] A collection mechanism for collecting the crushed samples; the collection mechanism includes a cavity 9 opened in the workbench 1 and a funnel 12. The funnel 12 is embedded in the workbench 1, and the lower end of the funnel 12 extends into the inner cavity of the cavity 9. The funnel 12 penetrates through the outside and the inner cavity of the workbench 1. A crushing blade 15 is clamped on the funnel 12.

[0031] By providing a sample detection table including a workbench 1 and a top plate 3, a crushing mechanism including a hydraulic cylinder 4 and a pressing head 5 is provided on the top plate 3 for crushing rock and soil samples. A collection mechanism including a cavity 9 and a funnel 12 is also provided. A plurality of groups of crushing blades 15 arranged vertically and horizontally are provided at the top of the funnel 12. During actual use, the door panel 10 is opened, the collection box 16 is placed in the cavity 9, and the collection box 16 is directly opposite to the lower end of the funnel 12. The rock and soil samples are placed on the crushing blades 15. The hydraulic cylinder 4 is started to drive the pressing head 5 to descend until the pressing head 5 cooperates with the crushing blades 15 to crush the samples. The crushed debris enters the cavity 9 through the blade gaps and the funnel 12 and falls into the collection box 16. The staff can open the door panel 10 and take out the collection box 16 for detection.

[0032] Generally speaking, the structure of this device is simple and easy to use. Through the cooperation of the crushing mechanism and the collection mechanism, the rock and soil samples can be directly collected after being crushed. The rock and soil debris is not easy to remain in the working area, which not only facilitates the subsequent detection work, improves the detection efficiency, shortens the detection process, but also, there is no need for the staff to manually collect and clean, providing great convenience for the staff and is worthy of being vigorously promoted.

[0033] In addition, please refer to Figures 3-5 :

A protective plate 11 for preventing debris of the geotechnical sample from splashing is arranged on the workbench 1, and the protective plate 11 is arranged in a cylindrical shape. A clamping groove 13 is arranged at the top of the funnel 12, a clamping ring 14 is clamped in the clamping groove 13, and the crushing blade 15 is arranged inside the clamping ring 14.

[0035] By clamping the crushing blade 15 with the clamping ring 14 at the top of the funnel 12, it is convenient to quickly combine and use the blade group and the equipment, and it can be quickly replaced after the blade is worn.

[0036] By arranging the cylindrical protective plate 11 on the workbench 1, when the indenter 5 crushes the geotechnical material, it can avoid the accident of debris splashing and hurting people, improve the safety of the equipment.

The inner and outer diameters of the clamping ring 14 are the same as the inner and outer diameters of the upper end opening of the funnel 12. The indenter 5, the protective plate 11, the clamping ring 14 and the funnel 12 are arranged coaxially, and the diameter of the indenter 5 is equal to the inner diameter of the clamping ring 14.

[0038] There are also multiple groups of convex columns 6 with rounded ends distributed at the bottom of the indenter 5. By the way of the indenter 5 cooperating with the crushing blade 15 to crush the geotechnical material, the top and bottom of the geotechnical sample can be evenly stressed, making it easier to be crushed, reducing the crushing difficulty of the sample and improving the crushing efficiency.
