Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, and in particular to a construction method of an assembled steel trestle combination system. Background Art

[0002] With the acceleration of urbanization, the demand for infrastructure construction is increasing, especially steel trestles, as important transportation facilities, which play an important role. However, the construction method of traditional steel trestles faces many challenges in the following aspects:

[0003] The construction of traditional steel trestles often relies on on-site processing, which requires a lot of welding, cutting and assembly, resulting in a long construction period, unstable construction period, and affecting the progress of the project. During the construction process, due to the lack of real-time monitoring means, the sealing state is difficult to guarantee. If the seal fails, it may cause structural deformation or damage, posing a safety hazard to construction personnel and subsequent use. The construction of steel trestles is usually accompanied by the generation of noise and waste. Traditional construction methods have failed to effectively control noise pollution, affecting the lives of surrounding residents and the ecological environment. Because traditional construction relies on manual operation, it is difficult to achieve precise control, resulting in uneven quality of each component, affecting the stability and durability of the overall structure. Traditional construction methods have limited monitoring methods for on-site conditions and lack effective data recording and feedback systems. It is impossible to obtain construction progress and quality in real time, which increases the complexity of management.

[0004] In view of the above problems, the present invention proposes a construction method for a prefabricated steel trestle combined system, which effectively improves construction efficiency and safety while reducing environmental impact by adopting standardized prefabricated parts and intelligent monitoring technology. This method provides a new solution for infrastructure construction, conforms to the development trend of modern construction, and has important theoretical and practical significance. Summary of the invention

[0005] The present invention relates to a construction method of an assembled steel trestle combined system, which mainly includes the following key technical solutions:

[0006] Modular Design:

[0007] The steel trestle deck and its related components adopt standardized and prefabricated design to reduce on-site processing time and improve installation efficiency.

[0008] Intelligent monitoring system:

[0009] Pressure sensors and data acquisition units are installed in the inner cabin of the steel trestle board, and real-time monitoring of the sealing status is achieved through the controller.

[0010] The system sets a normal air pressure range and triggers an audible and visual alarm when the air pressure is abnormal, reminding construction workers to conduct inspections in a timely manner.

[0011] Integrated Noise Reduction System:

[0012] The inner compartment of the steel trestle deck is filled with polyurethane foam or mineral wool to reduce resonance and noise.

[0013] Noise reduction plates are welded and rubber pads are installed at the four corners of the bottom plate to further reduce the impact of noise on the surrounding environment.

[0014] Construction process optimization:

[0015] The use of prefabricated parts simplifies the installation process of the steel trestle and ensures that the components can be connected quickly and efficiently.

[0016] Introduce automated lifting devices to improve the safety and efficiency of lifting and installation.

[0017] Quality Control and Data Feedback:

[0018] During the construction process, real-time monitoring data records will provide a basis for subsequent analysis, help identify potential problems, and optimize construction management.

[0019] The system will record the detected abnormal conditions in the database for subsequent quality tracking and improvement.

[0020] The beneficial effects of the present invention are as follows: the application of prefabricated parts simplifies the on-site assembly process, reduces construction time and labor costs, and improves construction efficiency. The real-time monitoring system can quickly determine the sealing status and issue an alarm in time to effectively avoid safety hazards caused by sealing failure. Standardized materials and components are used to ensure the quality consistency of each part and improve the durability and reliability of the overall structure. Environmentally friendly materials (such as polyurethane foam or mineral wool) are used as noise reduction fillings to reduce the environmental impact during construction and meet the requirements of sustainable development. The monitoring data recorded by the system provides a basis for subsequent analysis, helps to identify potential problems, optimize construction plans, and improve the overall management level. The intelligent monitoring system can be remotely monitored, reducing dependence on on-site manpower and improving management efficiency. The system can dynamically adjust monitoring parameters and optimize according to the actual situation of the construction site, thereby improving adaptability. By improving construction efficiency and safety, possible accidents and failures are reduced, thereby reducing long-term maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
