GUI ZHILE / LIANG YUYANG / DENG SHILIN / FU JIANWU / WANG YING

The invention relates to the technical field of anti-floating anchor rod construction, and particularly discloses a rear anchor rod plug anti-seepage plugging structure and a construction method thereof.The rear anchor rod plug anti-seepage plugging structure comprises a foundation slab, a pre-buried steel sleeve arranged in the foundation slab and an anti-floating anchor rod arranged in the pre-buried steel sleeve, and two water stop flanges are arranged at the upper end of the pre-buried steel sleeve; the two water stop flanges are arranged at the top end of the embedded steel sleeve and the belly portion of the embedded steel sleeve respectively, the anti-floating anchor rod is vertically arranged in the embedded steel sleeve, the steel base plate is arranged on the anti-floating anchor rod, the top face of the steel base plate is flush with the top end face of the embedded steel sleeve, the finish rolling nut is arranged on the anti-floating anchor rod, and the finish rolling nut is welded to the steel base plate. According to the anti-floating anchor rod, a good anti-leakage effect can be achieved at the anti-floating anchor rod under various conditions, the hidden danger of leakage is reduced, and the later maintenance cost is reduced.

本发明涉及抗浮锚杆施工技术领域，具体公开了一种后置锚杆堵头防渗漏封堵结构及其施工方法，包括基础底板，设于基础底板内的预埋钢套管，以及设于预埋钢套管内的抗浮锚杆，预埋钢套管上端设有两个止水翼缘，两个止水翼缘分别设于预埋钢套管顶端和预埋钢套管腹部，抗浮锚杆竖向设于预埋钢套管内，抗浮锚杆上设有钢垫板，钢垫板顶面与预埋钢套管顶端面平齐，抗浮锚杆上设有精轧螺母，精轧螺母与钢垫板焊接，整体结构稳定，封堵效果好，保证了在各种条件下，都能够在抗浮锚杆处起到良好的防渗漏效果，减少渗漏隐患，降低后期维护成本。
