The invention discloses a combined supporting structure for treating dangerous rock mass and a construction method thereof. The combined supporting structure comprises micro steel pipe piles arranged in two rows on the lower dangerous rock mass, wherein pile top crown beams are arranged at the tops of the micro steel pipe piles; prefabricated concrete baffles are arranged between the micro steel pipe piles, the prefabricated concrete baffles are covered with meshes in a net hanging and spraying mixing mode, and PVC drainage pipes are arranged in the micro steel pipe piles; backfill concrete is adopted between the micro steel pipe piles and the dangerous rock mass for backfill treatment; and frame beams are arranged on the upper slope surface of the dangerous rock mass, prestressed anchor cables or anchor rods are arranged at the joints of the frame beams, the bottoms of the frame beams extend to the pile top crown beams, backfill soil is arranged in the frame beams, and grass seeds are planted in the backfill soil to play a greening role. Due to the fact that the construction speed of the micro piles is high, the development of deformation of the dangerous rock mass can be preliminarily controlled within a short time, and high efficiency is achieved; and meanwhile, the pile diameter of the micro steel pipe piles is small, the design composition is simple, the requirement for driving equipment is not high, and good economic efficiency is achieved.
本发明公开了一种治理危岩体的联合支护结构及其施工方法，包括在下部危岩体设有的双排布置的微型钢管桩，该微型钢管桩顶部设置桩顶冠梁；微型钢管桩之间设置预制混凝土挡板，预制混凝土挡板采用网片挂网喷混覆盖，并且在微型钢管桩中设有PVC排水管；微型钢管桩与危岩体之间采用回填混凝土进行回填处理；危岩体上部坡面设置框格梁，框格梁节点处设置预应力锚索或锚杆，框格梁底部延伸至桩顶冠梁，框格梁内设有回填土，回填土内种植草籽，起到绿化作用。由于微型桩施工速度快，可以在短时间内对危岩体变形的发展进行初步控制，具有较高效率；同时微型钢管桩桩径小、设计组成简单，打入设备要求不高，具有良好的经济性。
