Steel trestle steel pipe pile anchoring method for pile bottom anchor rod reinforcement
The invention relates to a steel trestle steel pipe pile anchoring method for pile bottom anchor rod reinforcement, and belongs to the technical field of building construction. The method comprises the following steps of (1) construction preparation; (2) pile sinking construction; (3) steel pipe pile cleaning; (4) determining the positions of anchor rods; (5) mounting a drilling machine and cleaning drilling holes; (6) mounting the anchor rods and exhaust holes; (7) grouting; and (8) pouring underwater concrete. According to the method, an auxiliary steel pipe pile is erected on the outer sideof a trestle steel pipe pile, and the steel pipe pile, an anchor rod reinforcement cage in the steel pipe pile and underground rock stratum are anchored to form a whole through concrete pouring, so that stability of the steel pipe pile is greatly improved, bearing capacity of a reinforced pile support is increased, design technical requirements and structural installation quality are met, later construction and operation safety are ensured; and meanwhile, an anchor rod reinforcement cage structure is utilized, so that welding difficulty is reduced, construction progress is effectively accelerated, labor intensity of workers is reduced, less labor, convenient construction and safety and quality guarantee are achieved, and therefore obvious comprehensive economic benefits and social benefits are realized.
一种桩底锚杆加固的钢栈桥钢管桩锚固方法，属于建筑施工技术领域。它包括1）施工准备；2）沉桩施工；3）清理钢管桩；4）确定锚杆位置；5）安装钻机、钻孔清孔；6）安装锚杆、排气孔；7）压浆；8）浇筑水下混凝土。本发明通过采用在支栈桥钢管桩外侧搭设辅助用钢管桩，并通过灌注混凝土将钢管桩、钢管桩内的锚杆钢筋笼和地下岩层进行锚固形成一体，大大地增加了钢管桩的稳定性，增加了钢筋桩支座的承载力，满足设计技术要求和结构安装质量，确保了后期施工和运营安全，且利用锚杆钢筋笼结构，减少了焊接的难度，有效加快了施工进度，降低工人劳动强度，所需人工较少、方便施工、保证安全和质量，具有明显的综合经济效益和社会效益。
