Underwater anchor cable construction method
The invention provides an underwater anchor cable construction method, which relates to the technical field of anchor cable construction, and comprises the following steps: drilling and lofting; installing a first section of casing pipe and a plurality of sections of casing pipes, and drilling; drilling until the depth exceeds the depth of the first-section casing of the set hole depth; pulling out the anchor cable drill rod, retreating to inject chemical slurry, and gradually forming a plugging body in the hole bottom, the first section of sleeve and the multiple sections of sleeves; an anchor cable drilling machine is used for drilling holes, plugging bodies in the multiple sections of sleeves are cleaned, and drilling is stopped when the designed hole depth is reached; an anchor cable, a free section anchor cable protection sleeve, an isolation centering support, a primary grouting pipe and a secondary grouting pipe are lowered; performing primary grouting to form an anchor cable grouting body; multiple sections of casing pipes are pulled out section by section, and during the period, secondary grouting is carried out once when one section of casing pipe is pulled out; a water swelling wooden plug is plugged into the lower end of the hole of the diaphragm wall to block the hole; the hole opening is blocked, and a cavity grouting body behind the wall is formed; and finishing holes. The hole forming stability of the anchor cable in the underwater sandy gravel stratum is guaranteed, and fine sand gushing from the bottom of a hole is prevented from blocking a sleeve.
本发明提出了一种水下锚索施工方法，涉及锚索施工技术领域，包括以下步骤：钻孔放样；安装首节套管和多节套管，钻孔；钻进至超过设定孔深首节套管深度；拔出锚索钻杆，后退注射化学浆液，孔底、首节套管和多节套管内逐步形成封堵体；使用锚索钻机钻孔，清理多节套管内的封堵体，钻至设计孔深时停止；下放锚索、自由段锚索防护套、隔离对中支架、一次注浆管及二次注浆管；一次注浆，形成锚索注浆体；逐节拔出多节套管，期间每拔出一节套管，进行二次注浆一次；将遇水膨胀木塞塞入地连墙的孔口下端处，对其进行封堵；对孔口进行封堵，形成墙后空腔注浆体；终孔。本发明保证锚索在水下砂卵石地层中成孔的稳定性，防止孔底涌出来的细砂堵塞套管。
