Bidirectional inclined prestressed arch foot construction process and equipment
The invention discloses a bidirectional inclined prestressed arch foot construction process and equipment, and relates to the technical field of bridge arch foot construction, and the bidirectional inclined prestressed arch foot construction process comprises the following steps: S1, building a drilling pile construction platform, burying a reinforcement cage framework after drilling operation, and pouring underwater concrete; s2, a ground supporting formwork structure is erected on the construction platform, reinforcing steel bars are pre-buried, and concrete is poured to form a bearing platform structure; s3, a supporting formwork is erected on the bearing platform structure, reinforcing steel bars are pre-buried, prestressed tendons are preset on the two sides, and concrete is poured to form an arch support; s4, steel jacket boxes are installed on the two sides of the skewback, and steel bars are embedded; and S5, the self-adaptive supporting structure is controlled by adjusting the height of the steel cylinder to support the steel jacket box, during arch springing construction, the contact plate is self-adaptive to the inclination of the steel jacket box, the adaptive range of construction equipment is increased, during formwork removal, the steel jacket box is extruded through the discharging part, in this way, thrust is applied to the overturning arm, and the steel jacket box can be supported through the self-adaptive supporting structure. And the contact plate and the overturning arm are automatically separated, so that the disassembly is convenient.
本发明公开了一种双向倾斜预应力拱脚施工工艺及设备，涉及桥梁拱脚施工技术领域，包括以下步骤：S1：搭设钻孔桩施工平台，钻孔作业后埋设钢筋笼骨架灌注水下砼；S2：在施工平台搭设地面支护模板结构并预埋钢筋，浇筑混凝土以形成承台结构；S3：在承台结构上搭设支护模板并预埋钢筋，并在两侧预设预应力筋，浇筑混凝土以形成拱座；S4：在拱座两侧安装钢套箱，并预埋钢筋；S5：通过调节钢筒的高度来控制自适应支撑结构对钢套箱进行支撑，本在进行拱脚施工时，接触板自适应钢套箱的斜度，增加施工设备的适配范围，在进行拆模时，通过卸料部挤压钢套箱，这样对翻转臂施加一个推力，使接触板和翻转臂自动进行分离，方便进行拆卸。
