河道工程施工围堰技术与实施要点分析

为提高河道施工质量,提高水资源开发利用效率。通过对河道施工围堰进行研究,分析施工围堰技术的工艺做法和适用范围。对吹填围堰、桩模围堰、钢板桩围堰3种常见围堰技术进行论述,明确河道施工围堰在现场施工期间的实施要点。从排水堵漏和施工监测2个层面探讨河道工程施工围堰技术应用的注意事项。结果表明,通过对施工围堰技术的应用,可以有效改善河水在河道里流通性,减少在施工中对一些土石的破坏,提高施工建设的生产效率,促进河道工程的良性生产建设。

In order to improve the quality of river construction and improve the efficiency of water resources development and utilization,we conducted the research on the river construction cofferdam,and made the analysis of the technological practice and applicable scope of the construction cofferdam technology.This paper discusses three common cofferdam technologies of hydraulic fill cofferdam,pile formwork cofferdam and steel sheet pile cofferdam,thereby makes clear the implementation points of river construction cofferdam during the on-site construction.The matters needing attention in the application of cofferdam technology in river engineering construction are discussed from two aspects:drainage leakage plugging and construction monitoring.The results show that the application of construction cofferdam technology can effectively improve the fluidity of river water in the river,reduce the damage to some soil and rock during construction,improve the production efficiency of construction,and promote the benign production and construction of river engineering.
