Anti-inclination anchoring method for water bored piles for main trestle construction
The invention discloses an anti-inclination anchoring method for water bored piles for main trestle construction. The anti-inclination anchoring method comprises the five steps of anchor pile presetting, prefabricated connecting beam suspension setting, connecting beam and anchor rod butt joint, anchor rod bottom end pouring method anchoring and prestressed tendon tensioning and fastening. According to the anti-inclination anchoring method, through a pouring anchoring structure of anchor rods, the bottom ends of the anchor rods are implanted into a rock layer; the anchor rods and connecting beams are additionally arranged between the bored piles, so that an integrated fastening force is formed at the top ends between the two sets of bored piles, and the water wave impact resistance is better compared with that of a single bored pile; and through a prestressed tendon tensioning mode, strong tension is formed at the two ends of a cylindrical pier and the connecting beams, so that the autorotation torsion of the anchor rods is better resisted, the anchor rods are not prone to rotating and loosening, and finally a stable two-pile connecting and permanently fixing structure is formed. The structure is durable, capable of resisting violent wind waves and suitable for complex hydrological working condition environments. The anti-inclination anchoring method can be extended to a rapid building mode of a multi-pile supported water simple platform and is worthy of popularization.
本发明公开了一种用于主栈桥施工的水上钻孔桩防倾斜锚固方法，包括锚固桩预设置、预制连接梁悬吊设置、连接梁及锚杆对接、锚杆底端浇注法锚固及预应力筋张拉紧固等五步骤。本发明通过锚杆的浇注锚固结构，使锚杆底端植入岩石层，通过在钻孔灌注桩之间加设锚杆和连接梁，使两组钻孔灌注桩之间的顶端形成一体的紧固力，相比单个钻孔灌注桩的抗水浪冲击力更好；本发明通过预应力筋张拉的方式使圆柱墩与连接梁两端形成较强的张力，从而更好地抵抗锚杆的自转扭力，使锚杆不易旋转松动，最终形成较为稳固的两桩连接永固结构，该结构经久耐用，可抗击剧烈风浪，适用于复杂水文工况环境。本发明可延伸为多桩支撑的水上简易平台的快速搭建方式，值得推广。
