Abstract
Description
Technical Field
[0001] This application belongs to the field of bridge construction monitoring technology, specifically relating to a bridge hanging basket monitoring and alarm integrated system and construction system. Background Technology
[0002] In bridge construction, continuous beams often utilize prestressed reinforced concrete, with a straight-web box girder cross-section. Construction control of continuous beams aims to ensure the accuracy of target parameters throughout the entire construction process, particularly the effective monitoring of the stress state and alignment of the completed bridge. The core objective of construction monitoring is to correct errors during construction, especially those affecting the final bridge's structural objectives, to ensure that the final structure's stress and alignment meet design requirements.
[0003] Existing monitoring systems have the following shortcomings: they typically only focus on a single working condition, such as displacement or tilt angle, and lack comprehensive monitoring capabilities; the equipment is difficult to issue alarms the instant an anomaly occurs, which may lead to safety hazards; the data between multiple module systems is not effectively integrated, resulting in low monitoring efficiency and difficulty in ensuring construction safety; and the real-time performance is insufficient, relying heavily on manual inspections, making it difficult to detect abnormal stress on key components (such as C-hooks and support structures) in a timely manner.
[0004] To effectively control errors during construction, real-time monitoring and automated adjustment are crucial. This application, particularly in the cantilever construction phase, employs precise monitoring technology to ensure that deviations in beam segment position, stress, and internal forces remain within reasonable ranges. This avoids problems such as abnormal formwork displacement and tilt deviations caused by asymmetrical stress or asynchronous movement. By applying multi-sensor integration technology, the system can capture various factors affecting structural stress and alignment in real time, providing strong assurance for the safe implementation of cantilever construction. Utility Model Content

Detailed Implementation
[0024] The present application will be further described below with reference to specific embodiments and accompanying drawings.
[0025] Example 1
[0026] refer to Figure 1 and Figure 2 As shown, a bridge hanging basket monitoring and alarm integrated system includes a main beam stress sensor 01, a frame stress sensor 02, a truss tilt sensor 03, a track distance measuring sensor 04, a video monitor 05, an environmental monitoring sensor, an alarm terminal, and a data processing module 06.
[0027] The main beam stress sensor 01 is used to monitor the stress on the beam structure. Embedded within the concrete, it continuously records the initial strain readings during the curing period of the concrete pouring. In subsequent construction processes, as beam segments undergo stress deformation, the main beam stress sensor 01 measures the micro-strain, thereby determining the strain of the concrete at the measuring point. Its main function is to provide monitoring data before the next critical process after each beam segment's concrete pouring, such as tensioning, closure, or system conversion, to control the overall beam alignment and deflection.
[0028] The main beam stress sensor 01 can be a steel wire measuring instrument used to monitor anchor bolt stress. It is embedded in the concrete and installed on the structural reinforcement at the root section of the segment. Model SCJM, range: 2000 kN, resolution: 0.1 kN, accuracy: 0.5% FS, six-chord, suitable for suspended steel bars with a diameter of 100 mm. The strain data from the main beam stress sensor 01 is transmitted in real time to the data processing module for further analysis.
[0029] The frame stress sensor 02 is used to monitor the shear and tensile forces at the steel structure connections. It mainly monitors the strain of the main load-bearing components of the hanging basket equipment itself during preloading, pouring, and movement to ensure the safety and stability of the frame structure.
[0030] The frame stress sensor 02 can be a surface-mounted strain gauge with a range of ±2500μe. It has a built-in electronic serial number, model number, and calibration parameters, and directly displays the strain value. The strain data from the frame stress sensor 02 is transmitted to the data processing module in real time for further analysis.
[0031] The truss tilt sensor 03 is used to monitor the tilt angle of the truss, i.e. the main body of the hanging basket. This angle is based on the absolute verticality of the truss (column) to the top plate of the beam. It is used to ensure that the hanging basket maintains a stable posture during construction and avoids uneven stress or structural damage due to abnormal tilt.
[0032] The truss tilt sensor 03 can be a dual-axis inclinometer with a measurement range of ±30°, a resolution of 0.001°, and a measurement accuracy of less than 0.1%FS. Data from the truss tilt sensor 03 is transmitted in real-time to the data processing module for further analysis.
[0033] The track-mounted distance sensor 04 is used to monitor the relative distance between the truss and the traveling track, thereby analyzing the travel deviation and traveling speed, ensuring the synchronous movement of the hanging basket and avoiding uneven structural stress caused by asynchronous movement.
[0034] The track-mounting distance sensor 04 is arranged on both sides to measure the difference in travel distance between the left and right sides of the hanging basket, monitor the displacement data of the hanging basket in real time and transmit it to the data processing module in real time. The data processing module provides synchronous control signals to the traction component. The track-mounting distance sensor 04 can be a laser rangefinder with a range of 30m, accuracy of ±1mm, resolution of 0.1mm and response time of 0.2s.
[0035] The video monitor 05 is used to capture video from key locations, such as the construction surface of cast-in-place beams. Specifically, it can be monitored in real-time by high-definition cameras, such as Hikvision 4MP starlight-level bullet / PTZ cameras, and features remote monitoring and playback capabilities. The video monitor 05 transmits the data to the data processing module in real time.
[0036] Environmental monitoring sensors are used to monitor environmental conditions such as wind speed, wind direction, temperature, and humidity at the construction site to assist construction operations. These sensors can be integrated environmental monitoring instruments with air temperature monitoring capabilities (temperature range: -40~70℃, temperature accuracy: ±0.2℃), air humidity monitoring capabilities (humidity range: 0~100%, humidity accuracy: 3%), wind speed measurement range: 0~30m / s, accuracy: ±1m / s, and wind direction measurement range: 360 degrees.
[0037] The alarm terminal includes audible and visual alarms and / or mobile terminals. The system has different alarm thresholds set. When monitored data exceeds the set range, the alarm module will automatically trigger an alarm, directly notifying monitoring personnel via the audible and visual alarm, or sending an alarm message via SMS or app to the monitoring personnel's mobile terminal (phone), ensuring that construction personnel can take appropriate safety measures immediately. The system also supports adjusting the alarm thresholds to adapt to the needs of different construction stages and environmental conditions.
[0038] The main beam stress sensor 01, the frame stress sensor 02, the truss tilt sensor 03, the track distance measuring sensor 04, the video monitor 05, and the environmental monitoring sensor are all connected to the data processing module 06 via a wireless communication module. The wireless monitoring method reduces the pressure of on-site manual inspection and improves the efficiency and accuracy of construction management.
[0039] The data processing module 06 uses a monitoring cloud platform to process monitoring data from strain, tilt, and distance sensors in real time, generating curves showing changes in force, displacement, and tilt. All data is uploaded to the remote monitoring cloud platform in real time via a wireless network, enabling remote real-time monitoring and data storage.
[0040] The main beam stress sensor 01 includes a flange angle sensor 011 and a bottom angle sensor 012, specifically monitoring the internal flanges and bottom angles of the beam to effectively control the overall beam alignment and deflection. The frame stress sensor 02 includes a truss crossbeam sensor 021 and a base frame crossbeam sensor 022, specifically monitoring the stress at the far end of the cantilever arm to ensure structural stability and safety. The truss tilt sensor 03 includes a truss column sensor 031, facilitating the determination of tilt angles using the truss columns as a reference. The track distance measuring sensor 04 includes a truss longitudinal beam sensor 041, facilitating the determination of the distance between the truss longitudinal beam and the traveling track.
[0041] This application integrates multiple sensor modules via wireless transmission technology to provide real-time monitoring of the entire hanging basket process, ensuring that all working conditions during construction remain within design limits. Simultaneously, the system can respond quickly and issue alarms in case of abnormalities, effectively improving construction safety and accuracy. Furthermore, this application employs laser rangefinder and inclinometer synchronous control technology to ensure the synchronicity of the hanging basket's left and right movement and the stability of its posture, which is crucial for structural stability during cantilever construction. This application significantly improves construction efficiency and safety, reduces the workload of manual inspections, and ensures precise control of the hanging basket during construction, reducing construction risks caused by errors.
