Modularized drilling platform suitable for inclined bare rock condition and application of modularized drilling platform
The invention provides a modular drilling platform suitable for an inclined bare rock condition. The modular drilling platform comprises a drilling platform body and branch trestles on the periphery of the drilling platform body. The drilling platform body comprises a bottom keel, the lower portion of the bottom keel is supported by a plurality of steel casings, a cross beam structure is arranged between the tops of the steel casings and the bottom keel, and the cross beam structure transmits supporting acting force. The bottom of the branch trestle is supported by a plurality of anchor piles, and the anchor piles are all inserted into a bare rock geological layer; the cross beam structure comprises a cross beam and a longitudinal beam which are fixed to the connecting plate in a cross mode, hanging beams are installed at the two ends of the cross beam and the two ends of the longitudinal beam, and steel base plates are arranged at the lower ends of the hanging beams. According to the drilling platform structure, the cross-shaped beam structure installed at the top of the steel casing is used as a platform supporting structure, the flexibility is high, the adaptability is high, and the problem that the construction difficulty of a supporting pile of a cross-sea deepwater inclined bare rock drilling platform is large is solved.
本发明创造提供了一种适用倾斜裸岩条件下的模块化钻孔平台，包括钻孔平台本体及钻孔平台本体四周的支栈桥；钻孔平台本体包括底龙骨，底龙骨下方由多个钢护筒形成支撑，在钢护筒顶部与底龙骨间设有十字梁结构，由十字梁结构传递支撑作用力；支栈桥底部由多个锚桩形成支撑，锚桩均插设于裸岩地质层中；所述十字梁结构包括呈十字型固定于连接板的横梁和纵梁，所述横梁的两端以及所述纵梁的两端均安装有挂梁，并在挂梁下端设有钢垫板。本发明提供的钻孔平台结构利用安装在钢护筒顶部的十字梁结构作为平台支撑结构，灵活度高，适应性强，解决跨海深水倾斜裸岩钻孔平台支撑桩施工难度大的问题。
