预制装配式桥梁检验标准研究分析

Research and Analysis of Inspection Standards for Prefabricated Bridges

摘要:

随着经济与技术的不断发展，桥梁建设作为传统的劳动密集型工程亟需进行工业化与产业化升级。预制装配技术的应用，能够大幅提高桥梁建设的自动化程度与生产效率，但与之对应的规范及标准的整体编制情况均滞后于现有技术发展，关于装配式混凝土桥梁的相关检验评定标准内容也尚不健全。通过对我国桥梁预制装配式构件检验的相关标准进行总结分析，对比了各标准之间的指标区别，得出结论有：现行的行业及地方标准对桥梁预制结构在尺寸、外观上的检验标准已较为系统完备，但在钢筋、灌浆套筒及管桩这类无法肉眼检测的指标规定上，仍需要进行进一步的补充修订。

Abstract:

With the continuous development of economy and technology, the bridge construction, as a traditional labor-intensive type, urgently needs industrialization and industrial upgrading. The application of prefabricated assembly technology can greatly improve the automation degree and production efficiency of the bridge construction, but the overall formulation of corresponding specifications and standards lags behind the development of the existing technology. The content of relevant inspection and evaluation standards for prefabricated concrete bridges is not yet sound. By summarizing and analyzing the relevant standards for the inspection of prefabricated components of bridges in China, the differences in indicators among various standards are compared. The conclusion is that the current industrial and local standards for the size and appearance inspection of bridge prefabricated structures have become relatively systematic and complete. However, the further supplementary revisions are still needed for indicators such as steel bars, grouting sleeves and pipe piles that cannot be visually detected.
