[0027] 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, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] To address the technical problems of existing auxiliary devices for inversion analysis of soil and rock parameters under complex geological conditions, this embodiment discloses the following technical content:

[0029] Please see Figures 1-6 An auxiliary device for inversion analysis of soil and rock parameters under complex geological conditions includes: a detection probe 1, a connecting cable 2, a reading instrument 3, a protective shell 4, a limiting ring 5, a mounting ring 6, a mounting cylinder 7, a fixing plate 8, a first gasket 9, a limiting rod 10, a first support spring 11, a limiting plate 12, a second gasket 13, a handle 14, a limiting block 15, and a second support spring 16.

[0030] First, as attached Figure 1As shown, a connecting cable 2 is installed on the upper end of the detection probe 1. The reader 3 is opened, and the left end of the connecting cable 2 is connected to the reader 3. The detection probe 1 is placed in the pit, and the data is read through the reader 3. The reader 3 and the detection probe 1 are mature technologies on the market. The outer side of the connecting cable 2 is provided with a limiting mechanism for easy installation and disassembly, which limits the detection probe 1 and the connecting cable 2 to facilitate monitoring operations. A protective shell 4 is fixed on the lower outer side of the reader 3 to protect the reader 3 and prevent damage to the internal parts when the reader 3 is placed on the ground. The lower longitudinal section of the protective shell 4 has an arc-shaped structure, which can effectively prevent corner deformation.

[0031] As attached Figure 2 and attached Figure 3 As shown, the limiting mechanism includes a limiting ring 5, a mounting ring 6, and a mounting cylinder 7. The limiting mechanism is installed on the foundation pit by the mounting ring 6 and the mounting cylinder 7. The mounting ring 6 is integrally provided below the limiting ring 5. The mounting cylinder 7 is fixed inside the mounting ring 6 and is connected to the outside of the foundation pit by a slot. The inner longitudinal section of the mounting cylinder 7 is inclined. The upper cross-sectional length of the mounting cylinder 7 is greater than the lower cross-sectional length, so that the mounting cylinder 7 fits tightly with the top of the foundation pit. The material of the mounting cylinder 7 can be rubber with high friction to ensure the stability of the connection with the foundation pit.

[0032] As attached Figure 4 Appendix Figure 5 and attached Figure 6 As shown, the limiting mechanism also includes a fixed plate 8, a first washer 9, a limiting rod 10, a first support spring 11, a limiting plate 12, a second washer 13, and a handle 14. Pushing the limiting block 15 downwards causes it to slide within the limiting ring 5 via the second support spring 16. The second support spring 16 is installed below the limiting block 15. The limiting block 15 compresses the second support spring 16, causing it to retract into the limiting ring 5. A handle 14 is fixed to the outside of the limiting plate 12. Pulling the handle 14 outwards causes it to move the limiting plate 12, adjusting the limiting position. The position of plate 12 is such that the limiting plate 12 is slidably connected to the limiting rod 10 via the first support spring 11, allowing the limiting plate 12 to slide on the outside of the limiting rod 10 which is connected to it in a slot. The first support spring 11 is wound around the outside of the limiting rod 10 and is installed between the limiting plate 12 and the limiting rod 10. When the limiting plate 12 compresses the first support spring 11, the limiting block 15 is released. The second support spring 16 pushes the limiting block 15 to rise, so that the limiting block 15 and the handle 14 are connected in a slot. The limiting block 15 plays a limiting role for the handle 14 and the limiting plate 12.

[0033] Adjust the connecting cable 2 to a suitable height, then press down on the limiting block 15. The elastic action of the first support spring 11 pushes the limiting plate 12 to reset. The inner side of the limiting plate 12 is fixed with a second gasket 13, so that the second gasket 13 and the connecting cable 2 are tightly fitted. The inner side of the fixing plate 8 is fixed with a first gasket 9, so that the connecting cable 2 is also tightly fitted with the first gasket 9. The inner side of the fixing plate 8 is symmetrically fixed with limiting rods 10 to ensure the stability of the limiting plate 12. The fixing plate 8 and the limiting plate 12 effectively clamp and fix the connecting cable 2, so that the limiting plate 12 is fixed.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
