Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of civil engineering, and particularly relates to a monitoring device for exposed bridge piers. Background Art
[0002] The monitoring of exposed highway bridge piers directly affects the safety and durability of bridges. Bridge piers are usually one of the most critical parts of bridge structures. They bear the weight of the superstructure and transfer these loads to the foundation. Usually, bridge piers are buried in the soil and then hardened with cement. If the cement hardening collapses or the soil under the cement hardened surface is washed away by water, part of the bridge pier will be exposed. When the problem of exposed bridge piers occurs, it may lead to partial or complete collapse of the bridge.
[0003] The common monitoring of exposed highway bridge piers is completed through manual inspection. Specifically, when maintenance staff inspect the bridge according to the specification requirements, they use vision to check whether there is an exposed situation of the bridge piers. The disadvantages of manual inspection are as follows:
[0004] (1) The timeliness of manual inspection is poor. Manual inspection usually checks the bridges under its jurisdiction at the time intervals required by industry specifications, and only then can it check whether there is an exposed problem with the bridge piers. Due to the long operating section and the fact that the staff cannot check all the time, the timeliness of manual inspection is poor. There is a situation where the bridge piers have been exposed for a long time before being discovered by the staff.
[0005] (2) The detection efficiency of manual inspection is low. Since highway bridges are usually built among mountains, when the staff want to check the piers, they often need to climb down the bridge to check, or rent a bridge inspection vehicle to check the bridge piers. Therefore, it takes a lot of time to complete the inspection of the exposed problem of bridge piers.
[0006] (3) The safety risk of manual inspection is high. Manual inspection requires the staff to climb down the bridge or use a bridge inspection vehicle for visual inspection. It is very steep and difficult to get from the highway surface to the lower part of the bridge. If the staff are not careful, they will be injured. Although the bridge inspection vehicle does not require climbing, when the vehicle stays on the highway section, there is a risk of being collided by other vehicles.
[0007] The labor cost of manual inspection is high. Manual inspection mainly requires the staff to spend a lot of time on inspection. If the operating company wants to quickly complete the inspection of exposed bridge piers, it needs to hire more staff to work together. If a bridge inspection vehicle is used to assist in the inspection, more costs will be incurred. Content of the Utility Model
[0008] In view of the problems existing in the above-mentioned prior art, the utility model provides a monitoring device for the exposed part of a bridge pier column. The purpose is to use a distance measuring sensor to monitor the distance between the fixed plane of the bridge pier column and each splicing part in real time, monitor the change of the distance between the fixed plane of the bridge pier column and the device in real time, and transmit the distance change information to the terminal device in real time, so that the staff can view the exposed situation of the pier column of any bridge through the terminal device in time, so as to improve the detection efficiency, reduce the safety risk of checking the exposed problem of the bridge pier column and reduce the labor cost.
[0009] In order to achieve the above purpose, the specific scheme of the utility model is as follows:
[0010] The monitoring device for the exposed part of a bridge pier column includes a splicing ring, which is formed by splicing a plurality of splicing parts into a fully enclosed shape. The splicing part includes a splicing shell, a convex block, a groove adapted to the convex block, an anti-slip part and a distance measuring sensor. The convex block and the groove are respectively arranged at both ends of the splicing shell. An electromagnet is arranged on the convex block, a metal part is arranged in the groove, the anti-slip part is arranged on the side close to the surface of the bridge pier column, and the distance measuring sensor is arranged at the bottom of the splicing shell.
[0011] Furthermore, it includes a control chip, a GPS module, an NBIOT module and a power supply arranged in the splicing shell. The control chip is connected to the NBIOT module and the distance measuring sensor, and the power supply provides the working voltage for the control chip, the distance measuring sensor and the electromagnet respectively.
[0012] Furthermore, it further includes a terminal device, which is respectively connected to the GPS module and the NBIOT module. The terminal device is a mobile phone, a computer or a laptop computer.
[0013] Furthermore, the anti-slip part is hemispherical, square, circular or trapezoidal, and the anti-slip part is made of rubber material.
[0014] Furthermore, the splicing shell is square, arc-shaped, triangular, cylindrical or trapezoidal, and the splicing shell is made of nitinol, silica gel or rubber material.
[0015] Furthermore, the number of the splicing parts is set according to the size of the bridge pier column.
[0016] Furthermore, the metal part is made of iron, cobalt or nickel.
[0017] Advantages of the utility model
[0018] (1) The bridge pier column exposure monitoring device of the present utility model uses a ranging sensor to monitor the distance between the fixed plane of the bridge pier column and each splicing part in real time. When the situation of bridge pier column exposure occurs, it can timely detect the change in the distance between the fixed plane of the bridge pier column and the device, and transmit the distance change information to the terminal device in real time through the NBIOT module. The staff can directly view the exposure situation of the pier columns of any bridge through the terminal management system equipped in the terminal device, which can effectively improve the detection efficiency.
[0019] (2) This monitoring device uses a ranging sensor and an NBIOT module to automatically complete the monitoring of bridge pier column exposure remotely. The staff can view and understand the exposure situation of bridge pier columns in real time without having to climb the bridge or take a bridge inspection vehicle to the site additionally, reducing the safety risk of inspecting the exposure problem of bridge pier columns.
[0020] (3) This monitoring device only needs to invest staff for installation at the beginning, and subsequent monitoring work can be completed without manual on-site inspection, greatly reducing the labor cost. Description of the Drawings
