Abstract
Description
Technical Field
[0001] This utility model relates to the field of settlement observation technology, specifically a settlement observation structure based on uneven settlement at the joint between old and new bridges. Background Technology
[0002] Bridge settlement monitoring is a crucial means of ensuring the safe operation of bridges. By monitoring bridge settlement, abnormal deformation can be detected in a timely manner, the bridge's load-bearing capacity and safety can be assessed, and a scientific basis can be provided for bridge maintenance and management.
[0003] Bridge settlement monitoring generally employs the precision leveling method: by using a precision level to measure the settlement of bridge piers and abutments, it has the advantages of high accuracy and good stability, and is suitable for monitoring various types of bridges.
[0004] However, existing settlement monitoring structures based on uneven settlement at the joint between old and new bridges have the following problems during use: traditional settlement monitoring columns are exposed to the external environment all year round and are easily subject to collisions and malicious impacts. When surveyors take measurements at regular intervals, if the settlement monitoring points are found to be damaged, measurements cannot be taken and the deformation of the bridge cannot be effectively monitored. Utility Model Content
[0005] The purpose of this invention is to provide a settlement observation structure based on uneven settlement at the joint between old and new bridges, so as to solve the related problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a settlement observation structure based on uneven settlement at the joint between new and old bridges, comprising a pier, a roadbed, side settlement observation columns, and a bottom settlement observation column. The top of the pier is provided with a roadbed, and the side walls of the roadbed are provided with side settlement observation columns. The side walls at the bottom of the pier are provided with bottom settlement observation columns. The outer wall of the pier is provided with a protective frame for protecting the position of the bottom settlement observation columns. The outer walls of the pier near the bottom settlement observation columns are all equipped with upright plates, and pressure sensors that contact the bottom settlement observation columns are provided inside the upright plates.
[0007] This technical solution provides a settlement observation structure based on uneven settlement at the joint between old and new bridges, wherein the roadbed and pier sidewalls are equipped with measurement markings that are easy to view with a level instrument.
[0008] This technical solution provides a settlement observation structure based on uneven settlement at the joint between old and new bridges, wherein the protective frame is X-shaped.
[0009] This technical solution provides a settlement observation structure based on uneven settlement at the joint between old and new bridges, with an alarm device installed on one side of the roadbed.
[0010] This technical solution provides a settlement observation structure based on uneven settlement at the joint between old and new bridges. The output of the pressure sensor is electrically connected to the input of an external host computer via Bluetooth, and the output of the host computer is electrically connected to the output of an alarm via Bluetooth.
[0011] Compared with existing technologies, this utility model provides a settlement observation structure based on uneven settlement at the joint between old and new bridges, which has the following advantages:
[0012] 1. This utility model uses a pressure sensor attached to the side wall of the bottom settlement observation column. When the bottom settlement observation column is impacted, the pressure sensor will wirelessly transmit the information to the external host computer via Bluetooth. The measurement personnel can check the host computer to know and activate the alarm.
[0013] 2. This utility model involves setting up lateral settlement observation columns and bottom settlement observation columns on both sides of the splicing of new and old roadbeds. Surveyors regularly use a level to observe the settlement. However, it is inconvenient to set up a measuring rod on both sides of the splicing of new and old roadbeds. Instead, the measurement can be carried out by observing the position of the measuring line. This establishes a curve relationship between the settlement of the newly built roadbed and time, studies the uneven settlement law at the splicing of new and old roadbeds, provides a reference for the road construction time, reduces the risk of cracking at the splicing of new and old roadbeds, and can provide construction experience reference for splicing construction under similar conditions.

[0018] 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.
[0019] Example 1, as Figure 1-2As shown, this utility model provides a technical solution: a settlement observation structure based on uneven settlement at the joint of old and new bridges, including a pier 1, a roadbed 2, lateral settlement observation columns 3, and bottom settlement observation columns 4. The roadbed 2 is set at the top of the pier 1, and the lateral settlement observation columns 3 are set on the side walls of the roadbed 2. The bottom settlement observation columns 4 are installed on the side walls of the bottom of the pier 1. Measurement markings 5 are set on the side walls of the roadbed 2 and the pier 1 for easy viewing with a level instrument. By arranging lateral settlement observation columns on both sides of the joint of the old and new roadbeds 2... The surveying personnel regularly use a level to observe the settlement at the joint between the old and new roadbeds 2, including the measuring column 3 and the bottom settlement observation column 4. However, it is inconvenient to set up measuring rods on both sides of the joint, so the measurement can usually be carried out by observing the position of the measuring line 5. The surveying personnel will conduct regular observations and record the data. By establishing a curve relationship between the settlement of the new roadbed 2 and time, the uneven settlement law at the joint between the old and new roadbeds 2 can be studied, providing a reference for the road construction time, reducing the risk of cracking at the joint between the old and new roadbeds 2, and providing construction experience reference for joint construction under similar conditions.
[0020] Example 2, as Figure 1-3 As shown, this utility model provides a technical solution: a settlement observation structure based on uneven settlement at the joint between old and new bridges, including a protective frame 6 on the outer wall of the pier 1 for protecting the bottom settlement observation column 4. The protective frame 6 is X-shaped. The bottom settlement observation column 4 is exposed at the bottom of the pier 1, and the protective frame 6 can protect the bottom settlement observation column 4. The X-shaped protective frame 6 can prevent impact on the bottom settlement observation column 4 from the top, bottom, left and right, thus preventing deformation of the bottom settlement observation column 4. This structure can protect the bottom settlement observation column 4.
[0021] Example 3, as Figure 1-3 As shown, this utility model provides a technical solution: a settlement observation structure based on uneven settlement at the joint of old and new bridges, including a vertical plate 7 installed on the outer wall of the bridge pier 1 near the bottom settlement observation column 4, and a pressure sensor 8 in contact with the bottom settlement observation column 4 is installed inside the vertical plate 7. An alarm 9 is installed on one side of the roadbed 2. The output end of the pressure sensor 8 is electrically connected to the input end of an external host computer via Bluetooth, and the output end of the host computer is electrically connected to the output end of the alarm 9 via Bluetooth. Since the pressure sensor 8 is attached to the side wall of the bottom settlement observation column 4, when the bottom settlement observation column 4 is impacted, the pressure sensor 8 will wirelessly transmit the information to the external host computer via Bluetooth. The measurement personnel can check the host computer and then know and activate the alarm 9 to issue an alarm.
[0022] Working Principle: First, an external power supply is connected. Surveyors set up lateral settlement observation posts 3 and bottom settlement observation posts 4 on both sides of the splice between the old and new roadbeds 2. Surveyors periodically observe the settlement using a level. Since setting up measuring rods on both sides of the splice is inconvenient, measurements are typically taken by observing the position of the measuring lines 5. Surveyors periodically observe and record the data. By establishing a curve relationship between the settlement of the newly constructed roadbed 2 and time, the uneven settlement pattern at the splice of the old and new roadbeds 2 is studied, providing a reference for pavement construction timing, reducing the risk of cracking at the splice of the old and new roadbeds 2, and providing construction experience reference for splicing construction under similar conditions. The bottom settlement observation column 4 at the bottom of pier 1 is exposed, and the protective frame 6 protects the bottom settlement observation column 4. The protective frame 6 is X-shaped, so it will not impact the bottom settlement observation column 4 from the top, bottom, left and right, thus preventing the bottom settlement observation column 4 from deforming. This structure can protect the bottom settlement observation column 4. Furthermore, a pressure sensor 8 is attached to the side wall of the bottom settlement observation column 4. When the bottom settlement observation column 4 is impacted, the pressure sensor 8 will wirelessly transmit the information to the external host computer via Bluetooth. The measurement personnel can check the host computer and know that the alarm 9 has been activated to issue an alarm.
