Description

Technical Field

[0001] This utility model belongs to the technical field of settlement detection, and relates to a settlement detection device for concrete bridges. Background Technology

[0002] During the construction and use of bridges, settlement may occur due to the bridge's own weight and other weights during use. Because of differences in geological conditions and load-bearing capacity at each pier location, different piers may experience varying degrees of settlement, affecting the structural quality of the bridge.

[0003] Currently, bridge settlement is primarily monitored using hydrostatic leveling systems or total stations. Hydrostatic leveling systems require establishing a benchmark at a stable location, installing a level at both the benchmark and the observation point, and setting up a water tank connected to the level at the benchmark. The degree of settlement is calculated by comparing the water pressure difference or liquid level change detected by the level at the benchmark and the observation point. However, regardless of whether it's water or other liquids like antifreeze, changes in temperature and evaporation can cause fluctuations in water pressure within the tank, potentially affecting the accuracy of the leveling instrument. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a concrete bridge settlement detection device, which effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A concrete bridge settlement detection device, comprising:

[0007] The first water tank is fixedly installed at a reference point at one end of the bridge.

[0008] A water supply tank is fixedly installed at a reference point at one end of the bridge, and the bottom and top of the water supply tank are provided with connecting pipes.

[0009] A peristaltic pump is installed in each of the connecting pipes, and a one-way valve is installed in the connecting pipe at the bottom.

[0010] The second water tank is installed at a reference point at the end of the bridge away from the first water tank;

[0011] A level instrument, which is installed at the reference point and the observation point;

[0012] Water pressure pipe and air pressure pipe, wherein the water pressure pipe and air pressure pipe are connected to the first water tank, the level instrument and the second water tank;

[0013] A level gauge is installed in the first water tank and the second water tank.

[0014] Optionally, the level gauge includes a water level gauge installed in the first water tank and the second water tank, and a hydraulic gauge installed on the water pressure pipe at the bottom of the first water tank and the second water tank.

[0015] Optionally, the water replenishment tank is equipped with the level gauge.

[0016] Optionally, the outside of the water pressure pipe is covered with an insulation layer, and a heating belt is installed between the insulation layer and the water pressure pipe. A circulation pump is installed at the water pressure pipe position at the bottom of the first water tank and the second water tank.

[0017] Optionally, the level is equipped with a gyroscope module.

[0018] Optionally, it also includes a mounting component, which is bolted to the observation point, the mounting component comprising:

[0019] Mounting plate, which is bolted to the observation point;

[0020] A hinge, which is fixedly mounted on the mounting plate;

[0021] Mounting plate, which is rotatably mounted on the end of the hinge away from the mounting plate;

[0022] A fixing bolt is threaded to the mounting plate, one end of the fixing bolt abuts against the mounting plate, and two fixing bolts are provided on both sides of the rotation axis of the hinge.

[0023] The level is mounted on the mounting plate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting up a water replenishment tank and installing a peristaltic pump on the connecting pipe, when the level gauge detects a change in the liquid level, the peristaltic pump will promptly drain or replenish water to maintain the water levels of the first and second water tanks.

[0026] 2. Temperature changes or other factors causing pipe blockage or damage can affect the level instrument's measurement results. By installing a first and a second water tank at both ends, the replenishment tank adjusts the first water tank when the water level changes. The level gauges in both tanks detect these changes. If the level changes in the second and first tanks differ, it indicates potential blockage or damage to the water pressure pipe. This allows for timely detection of abnormalities and maintenance of the water pressure pipe.

[0027] 3. At low temperatures, the liquid inside the water pressure pipe may freeze. By installing a heating belt, the pipe can be heated, and a circulating pump can be used to create flowing water, reducing the impact of freezing on the detection. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1 This utility model discloses a concrete bridge settlement detection device, including a first water tank 1 and a replenishment water tank 2. The first water tank 1 and the replenishment water tank 2 are fixedly installed at a reference point at one end of the bridge. The bottom and top of the replenishment water tank 2 are provided with connecting pipes 21, and peristaltic pumps 3 are installed in the connecting pipes 21. A one-way valve 31 is installed in the connecting pipe 21 at the bottom. A second water tank 11 is installed at the reference point at the end of the bridge away from the first water tank 1. A level 4 is installed at both the reference point and the observation point. A water pressure pipe 5 and an air pressure pipe 6 are connected between the first water tank 1, the level 4 and the second water tank 11. A level gauge 7 is installed in the first water tank 1 and the second water tank 11.

[0033] Specifically, reference positions are set at both ends of the bridge, and a first water tank 1 and a second water tank 11 are set at the two reference positions. The level instrument 4 is installed between the first water tank 1 and the second water tank 11. A water replenishment tank 2 is set at the position of the first water tank 1 and connected by two connecting pipes 21. When the water level in the first water tank 1 changes, the peristaltic pump 3 is used to drain or replenish water.

[0034] In this way, by setting up a water replenishment tank 2 and a peristaltic pump 3 on the connecting pipe 21, when the level gauge 7 senses a change in the liquid level, the peristaltic pump 3 will drain or replenish water in a timely manner to maintain the water levels of the first water tank 1 and the second water tank 11.

[0035] Meanwhile, temperature changes or other conditions causing pipe blockage or damage can also affect the measurement results of the level instrument 4. By setting up a first water tank 1 and a second water tank 11 at both ends, when the water level changes, the water supply tank 2 adjusts the first water tank 1. The level gauges 7 of the first and second water tanks 11 detect the level changes. If the level change trends of the second water tank 11 and the first water tank 1 are different, the water pressure pipe 5 may be blocked or damaged. This facilitates the timely detection of abnormalities and the maintenance of the water pressure pipe 5.

[0036] In some feasible configurations, both the first water tank 1 and the replenishment tank 2 are tanks containing water or other liquids such as antifreeze. Reference points are set at the settlement stabilization locations at both ends of the bridge. A level 4 is installed at each reference point as a control group. Observation points are set at the bridge inspection locations. After installing the level 4, it is connected to a water pressure pipe 5, an air pressure pipe 6, and a signal line. The signal line connects to a control terminal, which in turn connects to a peristaltic pump 3 and a level gauge 7 for program control. The construction and setup of the level 4, control terminal, reference points, and observation points are all existing technologies and will not be elaborated upon here. The connecting pipe 21 controls the liquid flow via the peristaltic pump 3, facilitating flow control and, consequently, level control. A one-way valve 31 is installed at the bottom of the connecting pipe 21 to prevent backflow of liquid from the replenishment tank 2 into the first water tank 1.

[0037] As a specific embodiment of the concrete bridge settlement detection device provided in the application, the level gauge 7 includes a water level gauge 71 installed in the first water tank 1 and the second water tank 11 and a hydraulic gauge 72 installed on the water pressure pipe 5 at the bottom of the first water tank 1 and the second water tank 11.

[0038] Overall, by setting up a water level gauge 71 and a hydraulic gauge 72, the liquid levels in the first water tank 1 and the second water tank 11 are monitored, making it easier to obtain liquid level information more accurately.

[0039] Furthermore, the water replenishment tank 2 is equipped with a level gauge 7.

[0040] It should be understood that by installing a level gauge 7 in the water replenishment tank 2, it is convenient to replenish the water replenishment tank 2 in a timely manner.

[0041] As another specific embodiment of the concrete bridge settlement detection device provided in the application, the outside of the water pressure pipe 5 is covered with an insulation layer, and a heating belt is installed between the insulation layer and the water pressure pipe 5. A circulation pump 51 is installed at the position of the water pressure pipe 5 at the bottom of the first water tank 1 and the second water tank 11.

[0042] Depending on the specific application scenario, the liquid inside the water pressure pipe 5 may freeze when the temperature is low. By setting up a heating belt, the pipe can be heated, and the circulating pump 51 can generate flowing water to reduce the impact of freezing on the detection.

[0043] In some feasible methods, the heating belt is arranged along the axial direction of the water pressure pipe 5, and the insulation layer is wrapped around the heating belt and the outside of the water pressure pipe 5.

[0044] As another specific implementation of a concrete bridge settlement detection device provided in the application, the level 4 is equipped with a gyroscope module.

[0045] It should be understood that by setting up a gyroscope module to sense the tilt state of the detection point, the state of the bridge can be sensed even when the height of the detection point has not changed, thereby improving the detection range of the level 4.

[0046] Further, please refer to Figure 2 It also includes mounting component 8, which includes mounting plate 81, hinge 82, mounting disc 83 and fixing bolt 84. Mounting plate 81 is bolted to the observation point. Hinge 82 is fixedly mounted on mounting plate 81. Mounting disc 83 is rotatably mounted on the end of hinge 82 away from mounting plate 81. Fixing bolt 84 is threaded to mounting disc 83. One end of fixing bolt 84 abuts against mounting plate 81. There are two fixing bolts 84 on both sides of the rotation axis of hinge 82. Level instrument 4 is mounted on mounting disc 83.

[0047] It should be understood that by setting the hinge 82 and the rotatable mounting plate 83, the level 4 can be tilted after installation, which makes it easy to adjust the level 4 to make the gyroscope horizontal, and can also make the pipeline easier to install.

[0048] In some feasible methods, the mounting plate 81 is rectangular and has through holes for bolt installation. The hinge 82 can be a hinge, and a bearing is fixedly installed on the hinge 82. The bearing of the hinge 82 is connected to the mounting plate 83, which is a circular plate. The level 4 is fixed to the mounting plate 83 by bolts. The fixing bolts 84 are located on both sides of the level 4. When the position is adjusted appropriately, the fixing bolts 84 are tightened to fix the relative position of the mounting plate 81 and the mounting plate 81. The fixing bolts 84 can be screws to facilitate a more stable position fixation on the surface of the mounting plate 81. At the same time, the fixing bolts 84 can also be spot welded after the position is fixed.

[0049] 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.
