Anchoring construction method capable of effectively filling reaming section
The invention relates to an anchoring construction method capable of effectively filling a reaming section, and belongs to the technical field of anchoring. A first steel sleeve is arranged along the connection position of the free section and the anchoring section, a second steel sleeve is arranged at the hole bottom of the anchoring section, the first steel sleeve and the second steel sleeve are connected through waterproof geotechnical cloth, a steel plate and a bearing plate are arranged on the first steel sleeve and the second steel sleeve respectively, and the first steel sleeve, the second steel sleeve and the waterproof geotechnical cloth form a closed space. A through hole is formed in the steel plate and used for being communicated with a grouting pipe for grouting operation; ground subsidence on the outer side of the foundation pit can be avoided, safety is high, cement soil for replacing the expanded part of the anchoring section can be fully discharged through the structure of the grouting pipe and the waterproof geotechnical cloth in cooperation with the construction method, the expanded part of the anchoring section is made of pure cement paste, the condensation speed of the cement paste of the expanded part of the anchoring section is increased, and the construction efficiency is improved. And the strength of cement paste of the expanded part of the anchoring section is improved, so that the anchor cable obtains larger bearing capacity.
本发明涉及一种能有效充填扩孔段的锚固施工方法，属于锚固技术领域；沿自由段和锚固段交接位置设置第一钢套管，锚固段孔底布置第二钢套管，第一钢套管和第二钢套管之间通过防水土工布连接，且第一钢套管和第二钢套管上分别设置钢板和承载板，将第一钢套管、第二钢套管、防水土工布形成封闭空间，且钢板上设置通孔用于连通注浆管进行注浆操作；本发明能够避免基坑外侧地面沉降，安全性较高，通过注浆管和防水土工布的结构配合其施工方法，能够充分排开置换锚固段扩大部分的水泥土，使锚固段扩大部分为纯水泥浆，提升锚固段扩大部分水泥浆的凝结速度，提高锚固段扩大部分水泥浆的强度，使锚索获得较大承载力。
