Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of embankment settlement monitoring, in particular to an embankment settlement monitoring device for an underlying goaf area. Background Art
[0002] With large-scale mineral mining and the formation of underground buildings, underground or surface rock layers are removed or destroyed, and underlying goaf areas are gradually formed. Due to the complexity and instability of underlying goaf areas, underlying goaf areas are prone to collapse, causing a series of environmental geotechnical engineering geological problems, such as ground subsidence, road cracking, and reduction of arable land. In the actual infrastructure construction process, it is inevitable to construct a road surface on the ground of the underlying goaf area, and to build embankments on both sides of the road surface. The embankment is a fill roadbed with the top surface higher than the original ground. It is a common road cross-section form in transportation engineering road construction. Because it is in the underlying goaf area, settlement monitoring is required during long-term use.
[0003] Settlement monitoring is generally carried out by setting indicator arrows that sink together on the embankment and the settlement plate, and setting a scale plate on the ground near the settlement plate for the indicator arrow to point to. The settlement height is recorded by the direction of the indicator arrow on the scale plate, and the need for maintenance of the embankment of this section is determined by the settlement amount. However, in the actual settlement process of the embankment, the embankment body and the settlement plate may not only experience longitudinal vertical settlement, but also inclined settlement, that is, deflection settlement to one side of the embankment, and the height change of the indicator arrow caused by this part of the settlement cannot be obviously converted into the height change of the scale plate pointed by the indicator arrow. In other words, the embankment and the settlement plate may deflect and settle, while the direction of the indicator arrow on the scale plate may not change or change slightly, resulting in errors in the monitoring of the settlement amount.
[0004] Therefore, it is necessary to invent a device for monitoring the settlement of embankments in underlying goaf areas to solve the above problems. Utility Model Content

[0020] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.
[0021] The utility model provides Figure 1-Figure 3 The shown device is a settlement monitoring device for an underlying goaf area embankment, comprising a settlement plate 1 and an embankment body 2 cast and formed on the top surface of the settlement plate 1. A U-shaped stand 4 is detachably installed at symmetrical positions on the top surface of the settlement plate 1. A first extension rod 10 with a controllable sliding distance is longitudinally slidably arranged between the top and bottom ends of the U-shaped stand 4. A height indication arrow 11 is connected to the end of the first extension rod 10. First angle indication arrows 13 are connected to symmetrical positions on the end surface of the first extension rod 10 away from the U-shaped stand 4. A vertical plate 14 is detachably plugged into the ground to match the U-shaped stand 4. A scale line for the height indication arrow 11 to point to is arranged on one side of the vertical plate 14 close to the U-shaped stand 4. Horizontal scale lines for the height indication arrow 11 to point to are arranged on the symmetrical sides of the vertical plate 14. An angle indicating arrow 13 points to an arc-shaped angle identification plate 16, and a second extension rod 18 that can rotate with the settlement direction is detachably installed in the middle between the two U-shaped seats 4, and second angle indicating arrows 20 are connected to the symmetrical positions of the end faces of the second extension rod 18. An annular angle identification plate 22 for the second angle indicating arrow 20 to point to is detachably installed in the middle between the two vertical plates 14. The height indicating arrow 11 at the initial position is pointed to the specified scale line of the vertical plate 14, and the first angle indicating arrow 13 is pointed to the specified position of the arc-shaped angle identification plate 16, and the second angle indicating arrow 20 is pointed to the specified position of the annular angle identification plate 22, as the initial height and angle of the settlement plate 1 and the embankment body 2.
[0022] A clamping column 23 is connected to the middle of the vertical middle section of the U-shaped seat 4 near the middle of the side of the embankment body 2, and a first cross plate 17 is detachably installed on the end of the second extension rod 18 near the embankment body 2. Both ends of the first cross plate 17 are respectively rotatably mounted on the corresponding clamping column 23. When the settlement plate 1 and the embankment body 2 settle to one side, the settlement plate 1 is in an inclined state at this time, so that the first cross plate 17 deflects synchronously, so that the deflection of the second angle indication arrow 20 is synchronized and unified with the settlement plate 1.
[0023] The top of the U-shaped seat 4 is threaded with a screw rod 5, and the part of the screw rod 5 located above the U-shaped seat 4 is threadedly sleeved with a nut 6 that can lock the position of the screw rod 5. The top of the screw rod 5 is connected with a turntable 7, and the bottom of the screw rod 5 is connected with a rotating column 9 that can rotate longitudinally and penetrate the bottom of the U-shaped seat 4. The end of the first extension rod 10 close to the embankment body 2 is connected with a sliding seat 8, and the sliding seat 8 is threadedly sleeved on the screw rod 5, and the end face of the sliding seat 8 is always in contact with the side surface of the vertical middle section of the U-shaped seat 4. By applying force to the turntable 7, the screw 5 is driven to rotate. Under the restriction that the end of the sliding seat 8 is in contact with the vertical middle section of the U-shaped seat 4, the sliding seat 8 slides longitudinally along the vertical middle section of the U-shaped seat 4, thereby changing the position of the scale line of the height indication arrow 11 pointing to the vertical plate 14, thereby adjusting the pointing position of the height indication arrow 11 to the initial position, and locking the rotation of the screw rod 5 by rotating the nut 6, thereby locking the position of the height indication arrow 11 and the U-shaped seat 4.
[0024] A cross frame 15 is connected to the middle of the two symmetrical side walls of the vertical plate 14, and the other ends of the cross frame 15 are respectively connected to the non-identification surfaces of the arc-shaped angle identification disk 16 at the corresponding position. A second cross plate 21 is commonly connected between the non-identification surfaces of the two vertical plates 14, and the annular angle identification disk 22 is detachably installed in the middle of one side wall of the second cross plate 21 close to the embankment body 2. On the one hand, the second cross plate 21 can strengthen the connection strength of the two vertical plates 14, and on the other hand, it can serve as an installation support for the annular angle identification disk 22.
[0025] A first chuck 12 is sleeved on one end face of the first extension rod 10 away from the U-shaped seat 4, and two first angle indication arrows 13 are respectively installed at symmetrical positions of the first chuck 12. A second chuck 19 is sleeved on one end face of the second extension rod 18 away from the embankment body 2, and two second angle indication arrows 20 are respectively installed at symmetrical positions of the second chuck 19. The centers of the first chuck 12 and the second chuck 19 can be used as the rotation centers of the first angle indication arrow 13 and the second angle indication arrow 20, and the centers of the first chuck 12 and the second chuck 19 are respectively consistent with the centers of the arc angle identification disk 16 and the annular angle identification disk 22, so that the deflection settlement amount is recorded by the first angle indication arrow 13 pointing to the arc angle identification disk 16 and the second angle indication arrow 20 pointing to the annular angle identification disk 22.
[0026] A mounting seat 3 is installed at the bottom of a side surface of the vertical middle section of the U-shaped stand 4 close to the embankment body 2 , and the mounting seat 3 can be detachably mounted on the top surface of the settlement plate 1 .
[0027] In the utility model, the initial height and angle of the settlement plate 1 and the embankment body 2 are determined by pointing the height indicating arrow 11 at the initial position to the designated scale line of the vertical plate 14, and by pointing the first angle indicating arrow 13 to the designated position of the arc angle identification disk 16, and by pointing the second angle indicating arrow 20 to the designated position of the annular angle identification disk 22. When the settlement plate 1 and the embankment body 2 undergo longitudinal height settlement, the height settlement amount is recorded by the change in the scale line of the vertical plate 14 pointed by the height indicating arrow 11; when the settlement plate 1 and the embankment body 2 undergo deflection settlement to one side, that is, the settlement plate 1 and the embankment body 2 deflect to one side, the first extension rod 10 and the second extension rod 18 are synchronously deflected with the settlement plate 1, so that the first angle indicating arrow 13 and the second angle indicating arrow 20 are synchronously deflected, so that the first angle indicating arrow 13 points to the arc angle identification disk The angle change of 16 and the angle change of the second angle indicating arrow 20 pointing to the annular angle identification disk 22 are respectively recorded at both ends and the middle of the settlement plate 1, so as to judge the actual deflection angle and deflection settlement. In the utility model, the longitudinal settlement of the settlement plate 1 and the embankment body 2 is recorded by the change of the height indicating arrow 11 pointing to the scale line of the vertical plate 14, and the deflection settlement of the settlement plate 1 and the embankment body 2 can be recorded by the angle change of the first angle indicating arrow 13 pointing to the arc angle identification disk 16 and the angle change of the second angle indicating arrow 20 pointing to the annular angle identification disk 22, so as to effectively avoid the situation that the change of the height indicating arrow 11 pointing to the scale line of the vertical plate 14 in the case of deflection settlement does not exist or the change is small, and the specific settlement of the settlement plate 1 and the embankment body 2 is judged by the height settlement and deflection settlement, so as to reduce the judgment error of the settlement and facilitate the subsequent maintenance of the embankment body 2.
[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
