DETAILED DESCRIPTION DETAILED DESCRIPTION

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments:

[0035] The roadbed stability change monitoring device in this embodiment includes:

[0036] The protective section, which is installed at the roadbed to be observed during use, specifically includes a pre-embedded plate 1 embedded in the roadbed. In this embodiment, a connecting cylinder 2 is installed at the center of the pre-embedded plate 1, and a measuring rod 3 is threaded onto the connecting cylinder 2. To improve the protective capability, a positioning seat 10 is installed on the pre-embedded plate 1 and located outside the measuring rod 3. A protective sleeve rod 9 is detachably installed above the positioning seat 10. This embodiment, for example... Figure 1 and Figure 2 The structure shown has a ring 8 at the upper end of the measuring rod 3 on the protective sleeve 9. A first baffle 4 is installed on the ring 8 for limiting the position. The protective sleeve 9 and the positioning seat 10 can form a protective structure outside the measuring rod 3, which can prevent the measuring rod 3 from being directly damaged by external force, and improve the protective performance of the measuring rod 3.

[0037] To facilitate replacement of structures damaged by external deformation, in this embodiment, the protective sleeve 9 is detachably mounted on the positioning seat 10. Specifically, as shown... Figure 3 As shown in the structure, in this embodiment, the bottom end of the protective sleeve rod 9 is provided with a sliding groove 14. A moving block 11 is slidably installed in the sliding groove 14 through a first spring 15. A first insert block 12 is installed on the other side of the moving block 11, and a paddle 13 is installed on the moving block 11. The paddle 13 can drive the first insert block 12 to move. Under the action of the first spring 15, the protective sleeve rod 9 can be locked onto the positioning seat 10 through the first insert block 12, making the protective sleeve rod 9 easy to install and remove.

[0038] It should be noted that this embodiment requires observation of roadbed stability. If settlement occurs, its changes need to be observed. Therefore, a structure for relative motion is considered in the design, i.e., a fixing part is installed in the compacted soil section far from the roadbed to be observed. In this embodiment, the fixing part specifically includes a reference ring sleeve 5 sleeved on the measuring rod 3. The reference ring sleeve 5 is equipped with a positioning component through the connecting rod 6 and the ring support plate 7. The positioning component is as follows: Figure 4As shown, for inserting in the tampered soil section away from the observation embankment to keep the structure stable, the guard part will change in height relative to the reference ring type sleeve 5 if the embankment is unstable; a horizontally arranged pointer 31 is arranged inside the reference ring type sleeve 5, and the pointer 31 is used to read the scale data on the measuring rod 3, and the data on the measuring rod 3 before and after observation can be read to understand the stability of the embankment.

[0039] Specifically, as shown in the structure, Figure 4 The positioning assembly includes a fixed insertion rod 16 detachably mounted on the ring type supporting plate 7, and a second baffle 17 is connected to the upper end of the fixed insertion rod 16 in this embodiment. The fixed insertion rod 16 is inserted into the ring type supporting plate 7, and a connecting screw 18 is detachably mounted between the second baffle 17 and the ring type supporting plate 7 to better fix the ring type supporting plate 7 and the fixed insertion rod 16. A rotating rod 22 is rotatably mounted at the axial center of the fixed insertion rod 16 and the second baffle 17, and a rotating handle 26 is connected to the upper end of the rotating rod 22.

[0040] As shown in the structure, Figure 4 A reinforcing unit is uniformly arranged on the rotating rod 22, and a first bevel gear 23 is coaxially arranged on the rotating rod 22. The reinforcing unit includes a horizontal frame mounting bin 19 horizontally mounted in the inner cavity of the fixed insertion rod 16. A lead screw 24 is rotatably mounted in the horizontal frame mounting bin 19 in this embodiment. A reinforcing nail 20 is threadedly mounted on one end of the lead screw 24 through a sliding block 21. A second bevel gear 25 is mounted on the other end of the lead screw 24 to engage the first bevel gear 23. The rotating rod 22 is rotated by rotating the rotating handle 26, thereby driving the lead screw 24 to rotate. The threadedly mounted reinforcing nail 20 moves horizontally under the action of the sliding block 21, and the reinforcing nail 20 can be inserted into the rod wall of the fixed insertion rod 16, as shown in Figure 1 and Figure 4 The reinforcing nail 20 can be stably connected with the tampered soil section away from the observation embankment.

[0041] In order to keep the locking function of the rotating rod 22, as shown in the structure, Figure 4 and Figure 5 A pull rod 27 is vertically inserted into the rotating handle 26, a baffle 28 is threadedly mounted at the bottom end of the pull rod 27, a second spring 30 is sleeved on the pull rod 27 between the baffle 28 and the rotating handle 26, and a second insertion block 29 is mounted below the baffle 28. When the reinforcing nail 20 is extended, a hole is formed in the second baffle 17 for inserting the second insertion block 29, thereby forming a locking structure.

[0042] After the device is installed, the reading of the measuring rod 3 at the initial state when the device is placed is read according to the construction situation of the construction site. After a period of testing, the data of the measuring rod 3 is read again. The stability of the embankment is judged according to the data difference, and the observation is completed.

[0043] It should be noted that if the embodiment of the utility model has the direction indication (such as up, down, left, right, front, back, etc.), the direction indication is only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture, if the specific posture changes, the direction indication also changes accordingly.

[0044] In addition, if the embodiment of the utility model has the description of "first", "second", etc., the description of "first", "second", etc. is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features.

[0045] For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the utility model is defined by the appended claims rather than the above description, therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the utility model.
