随着经济的快速发展,中国基础设施建设行业发展迅猛,有时需要在很多现状河道或者渠道上修建跨河、跨渠建筑物,在有条件限制时,需要对现状河道或者渠道的边坡进行开挖施工。钢板桩作为一种快速、有效并能显著减少开挖范围的临时支护方案,已经广泛应用于工程中的分离墙、河堤、码头、壁岸防护、临时围堰等。文章通过对钢板桩在南水北调总干渠渠道外坡开挖中的具体应用分析,对以后类似跨渠建筑物的修建提供参考。
With the rapid economic development, China’s infrastructure construction industry is developing rapidly. Sometimes it is necessary to construct cross-river and cross-canal buildings on many existing river channels or channels. When conditions are limited, the existing river channels or channels need to be opened Dig construction. As a kind of fast, effective and can significantly reduce the scope of excavation of the temporary support scheme, has been widely used in engineering separation walls, embankments, piers, wall protection, temporary cofferdam. Through the analysis of the concrete application of the steel sheet piles in the excavation of the outer channels of the main canal of the South-to-North Water Diversion Project, the article provides references for the construction of similar cross-ditch structures later.
