Novel concrete open caisson construction method adopting anchor cable pile tensioning sinking
The invention discloses a novel concrete open caisson construction method adopting anchor cable pile tensioning sinking, and the construction method specifically comprises the following steps: S100, planning a concrete open caisson construction position, and then drilling a plurality of pile position holes in the center of the wall of the concrete open caisson by using a rotary drilling rig, the depth of the pile position hole is higher than the designed depth of the concrete open caisson; s200, an anchor cable is fixed to the top end of a reinforcement cage, and the reinforcement cage is slowly placed into the pile position hole; then a proper amount of underwater concrete is injected into the pile position hole, and an anchor cable pile is formed after the underwater concrete is solidified; the anchor cable penetrates out of the ground from an empty hole above the anchor cable pile for later use; s300, concrete open caisson construction is conducted at the designed position, a concrete formwork needs to be erected at the construction position before construction, reserved holes are formed in the positions aligned with the anchor cables when the concrete formwork is erected, and the anchor cables penetrate to the top of the formwork from the bottom of the formwork; and then concrete is poured into the concrete formwork.
本发明公开了一种采用锚索桩张拉下沉的新型混凝土沉井施工方法，该施工方法的具体步骤具体如下：S100、规划好混凝土沉井施工的位置，然后再对其混凝土沉井井壁正中的位置利用旋挖钻机钻出多个桩位孔，并且桩位孔的深度要高于混凝土沉井设计的深度；S200、将锚索固定在钢筋笼顶端，并将钢筋笼缓慢的放入桩位孔内部；之后往桩位孔内部注入适量的水下混凝土，待水下混凝土凝固后形成锚索桩；而锚索从锚索桩上方的空孔穿出地面待使用；S300、在设计好的位置进行混凝土沉井施工，施工前要在施工位置搭设混凝土模板，且搭设混凝土模板时对齐锚索的位置设置预留孔，并将锚索从模板底部穿到模板顶部；然后往混凝土模板内部浇筑混凝土。
