The invention discloses a stone filling and island building construction bearing platform method for an underwater stone abrupt slope area. Grouting steel sleeves, thick steel bars and cement-water glass double-liquid slurry are used for forming composite small anti-slide piles to resist an island building body from sliding down into a river, so that the island building area and the backfill engineering quantity are reduced, the construction period and the construction cost are saved, and the construction safety can further be ensured. The grouting steel sleeves are not taken out, so that thelateral stability of a bearing platform foundation pit in the later period is improved, and foundation pit excavation safety is guaranteed. Curtain grouting of the periphery of a foundation pit and bottom sealing grouting of the bottom of the foundation pit are carried out by adopting the cement-water glass double-liquid slurry, bearing platform foundation pit water stopping is carried out, the water stopping effect is good, secondary water stopping is not needed in subsequent bearing platform foundation pit excavation, and maximization of economy, safety and practicability is achieved. Compared with the prior art, large equipment is not needed, a large number of steel structures are not needed, the structure is safe, the procedure is single, and economical efficiency is good. The problemthat the bearing platform in the underwater stone abrupt slope area is difficult to construct is solved.
本发明公开了一种水下石质陡坡区填石筑岛施工承台方法，利用注浆钢套管、粗钢筋以及水泥‑水玻璃双液浆组成复合小型抗滑桩，以抵抗填筑岛体向江中下滑移，减少了筑岛面积和回填工程量，既节省了工期和成本，又能保证施工安全。注浆钢套管不取出可提高后期承台基坑的侧向稳定性，保证基坑开挖安全。采用水泥‑水玻璃双浆液进行基坑周圈的帷幕注浆和基坑底部的封底注浆，进行承台基坑止水，止水效果好，后续承台基坑开挖无需进行二次止水，实现了经济性、安全性、实用性最大化。相对于现有技术，不需要大型设备，不需要大量钢结构，结构安全、工序较单一且经济性好。解决了水下石质陡坡区承台施工困难的问题。
