Offshore steel trestle guide hole construction method
The invention discloses an offshore steel trestle guide hole construction method. The method comprises the following steps that S1, construction preparation is conducted; s2, bridge abutment construction; s3, steel pipe pile machining; s4, constructing the first row of steel pipe piles; s5, mounting an upper structure of a first trestle; s6, double-row auxiliary buttress construction is conducted, specifically, two temporary steel pipes are settled on each of the two sides of the steel trestle to the bed rock surface through cooperation of a crawler crane and a vibratory hammer; s7, mounting the first part of the trestle in the second hole; s8, mounting a cantilever guide frame; s9, guide hole construction of the second row of steel pipe piles is conducted, specifically, the steel pipe piles are hoisted into positioning holes of a guide frame through a crawler crane, after perpendicularity is calibrated, a vibratory hammer is started to sink the steel pipe piles to the bedrock surface, the vibratory hammer is withdrawn, a percussion drill is adopted for percussion drilling in the steel pipe piles to a certain depth, then the vibratory hammer is adopted for pile sinking, and the operation is conducted alternately in sequence; s10, a second part of the second hole trestle is installed; s11, double rows of auxiliary buttresses move forwards; and S12, the rest trestle is constructed. The method has the advantages of quickening the construction progress and reducing the construction cost.
本发明公开了一种近海钢栈桥引孔施工方法，包括以下步骤：S1：施工准备；S2：桥台施工；S3：钢管桩加工；S4：第1排钢管桩施工；S5：第1孔栈桥上部结构安装；S6：双排辅助支墩施工：采用履带吊机配合振动锤在钢栈桥两侧各沉降两根临时钢管至基岩面；S7：第2孔栈桥第一部分安装；S8：悬臂导向架安装；S9：第2排钢管桩引孔施工：采用履带吊机将钢管桩吊至导向架的定位孔内，校准垂直度后开启振动锤将钢管桩下沉至基岩面，撤出振动锤，采用冲击钻机在钢管桩内冲击钻孔至一定深度，再采用振动锤沉桩，依次交替进行；S10：第2孔栈桥第二部分安装；S11：双排辅助支墩前移；S12：剩余栈桥施工。具有加快施工进度、降低施工成本的优点。
