[0002] With the continuous development of bridge construction, traditional bridge construction quality monitoring methods require a lot of manpower and material resources, especially in large bridge projects, where inspection work is cumbersome and time-consuming.

Stable chemical composition means that the raw material is not prone to chemical reactions or degradation during processing and use; force tolerance data reflects the tolerance of the raw material when subjected to various types of forces (such as tension, compression, shear, etc.). Then, the raw material strength index is obtained through processing using the preset raw material strength model.

Then it is compared with the preset quality index to obtain the quality index deviation rate. The quality index deviation rate is compared with the preset quality index deviation rate threshold. If the quality index deviation rate is greater than or equal to the quality index deviation rate threshold, it means that the actual construction quality is lower than the expected level, and it is necessary to send quality inspection failure information, and further measures may be taken to improve the construction process; if the quality index deviation rate is less than the quality index deviation rate threshold, it means that the actual construction quality meets or exceeds the expected level, and quality inspection pass information can be sent, and the subsequent bridge construction or delivery can continue; The calculation formula of the bridge quality inspection model is:

The cycle deviation rate is obtained and then compared with the preset cycle deviation rate threshold. If the cycle deviation rate is greater than or equal to the cycle deviation rate threshold, it means that the actual construction cycle exceeds the expected level, and there may be progress delays or inefficiency problems. It is necessary to send cycle excess information, and further measures may be taken to speed up progress or improve efficiency. If the cycle deviation rate is less than the cycle deviation rate threshold, it means that the actual construction cycle is within the expected range and the construction efficiency is normal. The normal cycle information can be sent, and subsequent work can continue as planned.

[0047] Among them, in order to obtain the bridge construction conflict index, the bridge layout consistency data, main component fit data and construction suitability data are extracted according to the bridge structure characteristic information.

Then, it is processed through the preset bridge analysis model to obtain the bridge construction conflict index. The higher the conflict index, the more conflicts and problems the bridge may encounter during the construction process, which requires more attention and solutions; The calculation formula of the bridge analysis model is:

These parameters reflect the physical response characteristics of the raw material when subjected to external forces; chemical composition stability data involves the proportion and stability of various chemical components in the raw material and the interaction between them. Stable chemical composition means that the raw material is not prone to chemical reactions or degradation during processing and use; force tolerance data reflects the tolerance of the raw material when subjected to various types of forces (such as tension, compression, shear, etc.). Then, the raw material strength index is obtained through processing using the preset raw material strength model. The higher the raw material strength index, it usually means that the raw material has better performance and stability during processing and use.

[0053] Among them, in order to obtain the bridge construction quality index and determine whether it meets the requirements, the bridge construction quality index is obtained by processing the bridge construction machine performance index, bridge construction conflict index and raw material strength index through the bridge quality inspection model. This index comprehensively reflects the overall quality level of the bridge during the construction process. Then it is compared with the preset quality index to obtain the quality index deviation rate. The quality index deviation rate is compared with the preset quality index deviation rate threshold. If the quality index deviation rate is greater than or equal to the quality index deviation rate threshold, it means that the actual construction quality is lower than the expected level, and it is necessary to send quality inspection failure information, and further measures may be taken to improve the construction process; if the quality index deviation rate is less than the quality index deviation rate threshold, it means that the actual construction quality meets or exceeds the expected level, and quality inspection pass information can be sent, and the subsequent bridge construction or delivery can continue; The calculation formula of the bridge quality inspection model is:

[0056] Among them, in order to ensure that the overall project cycle meets the requirements, the construction cycle data of multiple bridge sections within the preset time period are obtained and calculated, and the average construction cycle data is obtained and compared with the preset cycle threshold. The cycle deviation rate is obtained and then compared with the preset cycle deviation rate threshold. If the cycle deviation rate is greater than or equal to the cycle deviation rate threshold, it means that the actual construction cycle exceeds the expected level, and there may be progress delays or inefficiency problems. It is necessary to send cycle excess information, and further measures may be taken to speed up progress or improve efficiency. If the cycle deviation rate is less than the cycle deviation rate threshold, it means that the actual construction cycle is within the expected range and the construction efficiency is normal. The normal cycle information can be sent, and subsequent work can continue as planned.
