Anti-floating anchor rod structure penetrating through water-rich gravel bottom layer and construction method thereof
The invention provides an anti-floating anchor rod structure penetrating through a water-rich gravel bottom layer and a construction method thereof. The anti-floating anchor rod structure comprises agrouting hose, a grouting floral tube, fixing pieces and a plurality of steel bar bundles evenly distributed in parallel in the longitudinal direction, wherein the steel bar bundles are fixed throughthe fixing pieces, the bottom ends of the steel bar bundles extend to penetrate through the water-rich gravel bottom layer, the bottom end of the grouting hose and the top end of the grouting floral tube are in butt joint, fixedly connected and longitudinally arranged, the grouting floral tube is located on the water-rich gravel bottom layer, the top end of the grouting floral tube exceeds the water-rich gravel bottom layer by at least 20 cm, a guide head is arranged at the end of the bottom end of the grouting floral tube, and the grouting floral tube is positioned among the plurality of steel bar bundles and is fixedly connected with the steel bar bundles. According to the structure and the method, the steel bar bundles directly penetrate through the water-rich gravel layer to form a pile, anti-floating and mechanical normal hole forming construction is effectively enhanced, a pile casing is avoided, and meanwhile, the quality problems that during water-rich gravel layer penetrating,hole forming cannot be achieved, the pile forming pulling resistance is insufficient, the pile head forming bearing capacity is poor, and steel bars are exposed are solved, and the structure has theadvantages of being convenient and standard to construct and easy to manufacture and practical.
本发明提供一种穿富水砂砾底层抗浮锚杆结构及其施工方法，包括注浆软管、注浆花管、固定片及若干纵向平行均布的钢筋束，所述钢筋束通过固定片进行固定，且钢筋束底端伸至穿富水砂砾底层，所述注浆软管底端与注浆花管顶端对接并固定连接且纵向设置，所述注浆花管位于穿富水砂砾底层，其顶端超出穿富水砂砾底层至少20cm，所述注浆花管底端端头设有导头，所述注浆花管处于若干钢筋束中间并与钢筋束之间固定连接。本发明使钢筋束直接穿越富水砂砾层成桩，有效增强抗浮和机械正常的成孔施工，避免使用护筒，同时解决了穿富水砂砾层无法成孔、成桩抗拔力不足、桩头成桩持力差及露筋等质量问题，具有施工方便、规范，装置制作简单、实用等特点。
