破冰技术在松花江流域栈桥保护中的应用
|
摘要
针对哈大铁路客运专线第二松花江特大桥1083号、1084号水中墩施工过程中钢栈桥在凌汛期间的防护工作,详述了破冰桩施工、流冰路开设、流冰的破碎与疏导等钢栈桥的综合防凌保护措施。这些措施的成功应用,使钢栈桥顺利度过凌汛期,并为今后类似工程提供了宝贵的经验。
Based on the successful protection of the steel landing pier in the ice flood period during the construction of No.1083 and No.1084 in-water piers of the second super large bridge over the Songhuajiang River on Harbin-Dalian Passenger Railway Line,the paper describes the integrative measures to protect the steel landing pier against ice jamming floods by building ice-breaking piles,opening passages for drift-ice flowing,and breaking and channeling away of drifting ice.The successful implementation of these measures helped the steel landing pier successfully get over the ice-flood period and may provide valuable engineering experiences for other similar projects in future.
