Description

Technical Field

[0001] The utility model belongs to the technical field of engineering monitoring, and in particular relates to a pier settlement monitoring device. Background Art

[0002] A complete bridge is mainly composed of an upper structure, a lower structure and a support system. The lower structure mainly includes piers, abutments and foundations. As a building component supporting the upper structure, the piers transfer dead loads and live loads such as vehicles to the foundation, thereby ensuring the safety and stability of the bridge. However, under the action of load, each layer of soil within a certain depth will produce different degrees of compression deformation, resulting in settlement of the piers. In order to prevent harm caused by settlement and determine the control measures for settlement, it is necessary to monitor and feedback the settlement deformation data of the piers regularly.

[0003] A Chinese patent with publication number CN220062935U discloses a bridge settlement monitoring device, which consists of a mounting base, a mounting plate, a movable slide rail, a mobile monitoring component and a bridge connection component. A mounting groove is provided on the mounting plate in the middle position along its vertical direction, and two groups of movable slide rails are symmetrically arranged on both sides of the mounting groove. The surface of each group of mounting slide rails is fitted with a monitoring scale. Both sides of the mobile monitoring component are slidably arranged on the two groups of movable slide rails. One side of the bridge connection component is connected and fixed to the bridge, and the other side of the bridge connection component is connected to the mobile monitoring component through the mounting groove. The settlement amplitude of the bridge can be observed by comparing the monitoring scales on the mobile monitoring component and the mobile slide rail.

[0004] In actual construction, in addition to settlement, bridge piers may also tilt due to human factors, construction factors or environmental factors. When the above scheme is in use, the mounting plate is set perpendicular to the ground, and the two sides of the mobile monitoring component are slidingly set on two sets of mobile rails. When the bridge pier settles and tilts at the same time, there is an angle between the moving direction of the mobile monitoring component and the length direction of the mobile rail, which makes the measurement results of the above scheme prone to errors. Utility Model Content

[0005] The utility model aims to provide a pier settlement monitoring device to solve the problem that when the pier settles, it tilts and the measurement result is prone to errors.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pier settlement monitoring device comprises a monitoring component, a reference component, a support component and a scale rod, wherein the monitoring component comprises a mounting frame and a first sleeve, the mounting frame is transversely arranged on the side wall of the pier, and a U-shaped frame is fixedly arranged at one end of the mounting frame away from the pier, the top of the side wall of the first sleeve is rotatably connected to the side wall of the U-shaped frame, a first leveler is fixedly arranged on the top of the first sleeve, the reference component comprises a reference plate, the reference plate is transversely arranged above the adjacent soil foundation of the pier, the support component comprises a telescopic rod and a second sleeve, the telescopic rod is transversely fixedly arranged directly below the monitoring component, the second sleeve is rotatably arranged at one end of the telescopic rod away from the pier, the scale rod is slidably penetrated through the first sleeve and the second sleeve in sequence, and the bottom wall of the scale rod abuts against the top surface of the reference plate.

[0008] The principle and effect of this technical solution:

[0009] After the construction of the bridge is completed, a mounting frame is fixed on the side wall of the pier, and a reference plate is set above the adjacent soil foundation of the pier. The bottom end of the graduated rod is passed through the first sleeve and the second sleeve in turn, and abutted against the top surface of the reference plate. The length of the telescopic rod is adjusted to make the graduated rod rotate circumferentially along the top of the first sleeve until the first level indicates that the first sleeve is in a horizontal state. At this time, the graduated rod is perpendicular to the reference plate. The size of the alignment of the top of the first sleeve is recorded for the first time. In the next observation period, the above operation is repeated, and the difference with the first recorded data is compared, which is the specific settlement value of the settlement.

[0010] Through the above-mentioned arrangement, the scale rod is slid through the first sleeve and the second sleeve in sequence, and the length of the telescopic rod is adjusted to ensure that the scale rod remains vertical to the reference plate during each measurement. This can avoid errors in the measured settlement results caused by the inclination of the pier, thereby improving the accuracy of the measurement results of the utility model.

[0011] In the utility model, the monitoring component also includes a mounting plate, which is L-shaped, with side plates of the mounting plate fixedly connected to the side walls of the pier, a top plate of the mounting plate connected to the mounting frame via a first leveling member, and a second leveler fixedly arranged on the top of the mounting frame.

[0012] The principle and effect of this technical solution:

[0013] Before adjusting the length of the telescopic rod to make the first sleeve in a horizontal state, the first leveling member is first adjusted until the second leveler indicates that the mounting frame is in a horizontal state.

[0014] Through the above arrangement, it can be further ensured that the first sleeve is in a horizontal state, thereby improving the accuracy of the measurement result of the utility model.

[0015] In the utility model, a protractor is fixedly arranged on the side wall of the U-shaped frame in the vertical direction, and a reference line is arranged on a side wall of the first sleeve close to the protractor in the vertical direction.

[0016] The principle and effect of this technical solution:

[0017] When the pier tilts, the protractor and the mounting frame tilt with the pier. When the length of the telescopic rod is adjusted to make the first sleeve in a horizontal state, the reference line is perpendicular to the horizontal plane, and the angle between the protractor and the reference line is the inclination angle of the pier.

[0018] Through the above arrangement, the inclination angle of the pier can be measured while measuring the settlement of the pier, thereby improving the practicability of the utility model.

[0019] In the utility model, the reference assembly also includes an embedded plate, which is laterally arranged below the reference plate. The embedded plate and the reference plate are connected via a second leveling member, and a third leveler is fixedly arranged on the top of the reference plate.

[0020] In the utility model, a drill rod is fixedly arranged vertically on the bottom of the embedded plate.

[0021] The principle and effect of this technical solution:

[0022] Insert the drill rod into the soil foundation adjacent to the pier until the embedded plate contacts the top of the soil foundation, and adjust the second leveling member until the third leveler indicates that the reference plate is in a horizontal state.

[0023] When the pier is inclined and the scale rod is perpendicular to the horizontal plane, the contact position between the scale rod and the reference plate changes. The above arrangement ensures that during multiple measurements, the contact position between the scale rod and the reference plate is always located in the same horizontal plane, further improving the accuracy of the measurement results of the utility model.

[0024] In the utility model, the telescopic rod includes a fixed rod and a sleeve rod, one end of the fixed rod is fixedly connected to the side wall of the pier, one end of the sleeve rod is slidably sleeved on the other end of the fixed rod, a fastening bolt is threaded through the side wall of the sleeve rod, one end of the fastening bolt abuts against the fixed rod, and the other end of the sleeve rod is rotatably connected to the second sleeve. Through the above arrangement, the sleeve rod can be prevented from sliding along the fixed rod when the first sleeve is in a horizontal state, which is convenient for monitoring personnel to record data, thereby improving the practicality of the utility model.

[0025] In the utility model, the monitoring component, the reference component and the supporting component are respectively arranged in two groups and are arranged on two adjacent side walls of the pier. BRIEF DESCRIPTION OF THE DRAWINGS
