摘要
主要针对云南省地貌,两岸陡峭的V形山谷,进行桥梁桩基施工。无工作平台,施工便道工程量大,钻机、挖掘机等大型施工设备无法就位等问题导致桩基仅能选用人工挖孔桩。人工挖孔桩不具备钢筋笼直接吊装的桩基,采用孔口绑扎技术的具体施工方法及工艺。
This article mainly focuses on the topography of Yunnan Province and the steep V-shaped valleys on both sides of the bridge pile foundation construction.There is no working platform,a large amount of construction access,and large construction equipment such as drilling rigs and excavators cannot be placed in place.As a result,only manual digging piles can be used for pile foundations.The manual digging pile does not have the pile foundation directly hoisted by the steel cage,and adopts the specific construction method and technology of the hole binding technology.
