Description

Technical Field

[0001] The utility model relates to the technical field of soil inclination measuring equipment, in particular to soil stability monitoring equipment. Background Art

[0002] When a large-span continuous rigid frame bridge crosses an existing line, since the main pier is close to the slope of the highway embankment and the traffic volume on the highway is dense, the vibration generated by vehicle driving will affect the stability of the bridge foundation pit excavation, and the foundation pit excavation will also disturb the stability of the Beijing-Taipei Expressway roadbed. During the construction of the large-span continuous rigid frame bridge, in order to ensure the driving safety of the existing important highway trunk line and to be able to carry out the cast-in-place construction of the main structure of the bridge normally, it is necessary to conduct real-time monitoring of the deformation of the bridge foundation pit excavation adjacent to the existing highway.

[0003] The existing monitoring method usually adopts a guide wheel fixed inclinometer. When the guide wheel fixed inclinometer is used, a screw rod needs to be set in the inclinometer tube in advance. When a small range of deviation occurs in the measured area, the inclinometer tube tilts or bends, and the screw rod is in a vertical state and cannot deviate accordingly. The inclinometer will be squeezed by the inner wall, resulting in subsequent monitoring failure and deviation. There is room for improvement, so a soil stability monitoring device is proposed to solve the above problems. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-6 The utility model discloses a soil stability monitoring device for monitoring soil in goaf area 01, comprising:

[0039] An inclinometer 1, wherein the inclinometer 1 is arranged in a soil body 01, wherein an inclinometer tube 02 is arranged in the soil body 01, wherein a pulley block 11 in contact with an inner wall of the inclinometer tube 02 is arranged on the inclinometer 1, and wherein the inclinometer tube 02 is a tube body inserted into the soil body;

[0040] A power cover 2, the power cover 2 is arranged on the inclinometer tube 02, and a power unit 7 for driving the inclinometer 1 to move is arranged inside the power cover 2;

[0041] The fixing part 3 is fixed to the bottom of the inclinometer tube 02. The fixing part 3 and the power cover 2 are both provided with movable pulleys 6. A circulating transmission rope 4 is connected between two groups of the movable pulleys 6. The inclinometer 1 is fixedly arranged on the circulating transmission rope 4. The circulating transmission rope 4 is ring-shaped. The inclinometer 1 is fixed on the transmission rope 4 on one side of the ring to move with the circulating transmission rope 4 in the inclinometer tube 02 for monitoring.

[0042] When the present application is in use, a circulating transmission structure can be formed by setting the fixing part 3 on the bottom wall of the inclinometer tube 02, and then setting the circulating transmission rope 4 between the power cover 2 and the movable pulley 6 of the fixing part 3, and the inclinometer 1 is fixedly set on the circulating transmission rope 4, so under the drive of the power unit 7, the inclinometer 1 can be driven to move up and down in the inclinometer tube 02 to monitor the soil 01. It should be noted that the number of inclinometers 1 on the circulating transmission rope 4 can be multiple, and multiple inclinometers 1 connected in series can be used to collect measurement data of a multi-point omnidirectional displacement meter, and upload the data in a wired manner for subsequent monitoring.

[0043] In this embodiment, it is easy to imagine that a placement groove corresponding to the movable pulley 6 is provided on a side of the fixing member 3 opposite to the power cover 2 .

[0044] It should also be explained that a trigger pin 5 is provided on the side of the fixing member 3 opposite to the power cover 2, and triggers 13 corresponding to the trigger pin 5 are provided at the upper and lower ends of the inclinometer 1. The trigger 13 is used to change the running direction of the power unit 7 after being triggered, so as to make the inclinometer 1 run in an up and down cycle.

[0049] With the above-mentioned structural arrangement, when the device is in use, driven by the power unit 7, the inclinometer 1 on the circulating transmission rope 4 moves up and down along the inclinometer tube 02, and after the inclinometer 1 moves to one end, the trigger 13 on the inclinometer 1 contacts the trigger ejector pin 5, and the trigger 13 provides a feedback signal to the controller, and under the control of the controller, the power unit 7 is made to run in the reverse direction, thereby achieving the purpose of cyclic detection. It should be noted that the controller may also have a timing function to control the detection frequency of the inclinometer 1.

[0050] In the case of a plurality of inclinometers 1 connected in series, only the top of the uppermost inclinometer 1 and the bottom of the lowermost inclinometer 1 have triggers 13 to achieve the above-mentioned steering movement effect.

[0051] It should be noted that the inclinometer 1 is provided with two through holes corresponding to the circulating transmission rope 4 .

[0054] It should be noted that a counterweight 12 is provided at the bottom of the inclinometer 1 .

[0055] It is easy to imagine that the power cover 2 has a larger diameter than the inclinometer tube 02. The power cover 2 is provided with a locking rod 21 for fixing to the soil body 01 to facilitate the installation of the power cover 2. At the same time, the power cover 2 can also seal the inclinometer tube 02 to prevent foreign objects from entering the inclinometer tube 02.

If the specific posture changes, the directional indication will also change accordingly.

[0057] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0058] In addition, "plurality" means two or more.
