Construction process for underwater pile foundation of oil wharf
The invention discloses an oil wharf underwater pile foundation construction process which comprises the following steps: step 1, steel pile casing sinking: a guide frame is manufactured, the guide frame adopts an upper frame body and a lower frame body, the frame bodies are connected through a vertical rod piece, a fixed rod piece is mounted on the lower frame body, and an inclined strut is connected between the fixed rod piece and the upper frame body; the guide frame is fixed; hoisting the steel casing into a gathering opening, ensuring that the plane center of the steel casing is consistent with the center of the guide frame, observing and adjusting the perpendicularity of the steel casing, lowering the steel casing to a seabed, hoisting the steel casing to be driven, installing the steel casing to a top opening of the steel casing, hoisting an impact hammer, sleeving the steel casing into an upper opening of the driven, measuring and rechecking the position and the perpendicularity, and then sinking the steel casing; 2, drilling is conducted; step 3, finishing the hole and cleaning the hole; step 4, processing and transporting the reinforcement cage: processing the reinforcement cage in sections, transporting the reinforcement cage to a construction site, and hoisting the reinforcement cage into the pile hole; and 5, concrete pouring is conducted. The steel casing welding tool can guarantee the installation perpendicularity of the steel casing and guarantee the welding quality of the steel casing.
本发明公开了一种油码头水下桩基施工工艺，包括以下步骤：步骤1：钢护筒施沉：制作导向架，导向架采用上下双层架体，架体之间通过竖向杆件连接，下部架体上安装有固定杆件，固定杆件与上部架体之间连接有斜撑；将导向架固定；起吊钢护筒入拢口，确保钢护筒在该处平面中心与导向架中心一致，观测调整钢护筒垂直度，下放钢护筒至海床，吊起钢护筒替打，安装在钢护筒顶口，起吊冲击锤，套入替打上口，测量复核好位置及垂直度后施沉钢护筒；步骤2：钻孔；步骤3：终孔、清孔；步骤4：钢筋笼加工、运输：钢筋笼分节加工并运输至施工现场，将钢筋笼吊入桩孔内；步骤5：混凝土浇筑。本申请能够保证钢护筒安装的垂直度并保证钢护筒的焊接质量。
