桥桩间围堤堤基砂被施工技术的应用

Apolication of construction technology of dyke embankment sand cushion among bridge piles

本文介绍了桥桩间围堤堤基砂被施工工艺。在具体施工中,针对每个桥梁分别设计袋体形状和尺寸,在充袋施工前对袋体进行打桩固定,并在施工过程中及时调整输泥管口方向,保证了砂被原有功能且具有很强的操作性,同时确保了桥梁桥桩的安全。此工艺可为类似工程借鉴。

Cofferdam crossing harbor pier(bridge)is affected by bridge piles,it is impossible to to pave ordinary sandbags usually.In addition,the bridge pile is susceptible to extrusion of mud filling pipe bag,thereby affecting the safety of trestle(bridge).In the paper,the construction technology of dyke embankment sand cushion among bridge piles is introduced.In the construction process,the bag shape and size are respectively designed aiming at each bridge.The bags are piled and fixed before bag filling construction,and the mud pipe orifice direction is adjusted timely during construction process,thereby guaranteeing original functions of sand cushion and strong operability,and ensuring the safety of the bridge pile.This process can be used as reference for similar projects.
