Description

Technical Field

[0001] This utility model relates to the technical field of box girder maintenance devices, and in particular to a cast-in-place box girder maintenance device. Background Technology

[0002] With the continuous development of transportation infrastructure construction, bridge engineering, as a key component, is constantly increasing in scale and complexity. Cast-in-place box girders, with their excellent structural performance, strong adaptability, and aesthetics, have become the preferred structural form for long-span bridges and urban overpasses. Driven by the demand for increased bridge loads and shorter construction cycles, the application of cast-in-place box girders is becoming increasingly widespread. However, they are extremely sensitive to changes in temperature and humidity during the hardening process. Even slight errors in curing can cause rapid moisture loss from the concrete surface, making cracks highly likely to appear before demolding or even before final setting, seriously threatening the durability and load-bearing capacity of the cast-in-place box girder. Therefore, scientific and effective maintenance is crucial to ensuring the quality of cast-in-place box girders. As the scale of bridge construction continues to expand, higher requirements are placed on the quality and efficiency of cast-in-place box girder maintenance. In some large-scale bridge projects, the construction period is tight, and traditional maintenance methods are time-consuming and labor-intensive, seriously affecting the construction progress. Furthermore, with the increasing awareness of environmental protection, attention is being paid to the energy-saving and environmentally friendly performance of maintenance devices. Therefore, it is urgent to develop a cast-in-place box girder maintenance device that can accurately control temperature and humidity, save water efficiently, and has a high degree of automation and intelligence. This has important practical significance for improving the quality of bridge projects and promoting technological progress in the industry.

[0003] Currently, box girder curing devices on the market mainly consist of intelligent temperature control systems and high-efficiency humidity control systems. Concrete curing essentially involves the setting and hardening stage after pouring, where temperature and humidity are rationally controlled to ensure proper hydration of the cementitious materials, allowing the concrete to reach its expected strength and possess excellent properties. Proper curing can significantly reduce concrete cracks, ensure structural safety, and enhance the structure's ability to resist environmental factors. For large-volume concrete construction, it is crucial for improving the quality of the finished product. However, traditional cast-in-place box girder curing methods often combine manual watering with natural curing. This method has many drawbacks. Natural curing is greatly affected by environmental humidity and temperature, and it is difficult to maintain the desired curing conditions in dry, hot, and windy weather. The concrete surface is in a suitable moist state, causing the concrete to lose water too quickly, leading to cracks and insufficient strength. Most existing cast-in-place box girder curing devices focus on optimizing the spraying system and controlling temperature and humidity, but neglect the crucial step of curing liquid mixing. Some devices use simple storage tanks to directly supply curing liquid without any mixing measures. After long-term storage, the curing liquid stratification is particularly obvious, seriously affecting its performance. Even if some devices have mixing functions, they suffer from problems such as single mixing methods and poor mixing effects. Some devices only use manual mixing, which is not only inefficient and difficult to meet the needs of large-scale construction, but also results in uneven mixing and cannot effectively solve the problem of curing liquid stratification.
