The invention discloses a miniature pile and anchor cable combined supporting structure for treating dangerous rock mass and a construction method of the miniature pile and anchor cable combined supporting structure. The structure comprises miniature steel pipe piles arranged in double rows, wherein pile top crown beams are arranged at the tops of the miniature steel pipe piles, and the pile top crown beams connect the double rows of piles to enable the double rows of piles to be integrally and synergistically stressed; prefabricated concrete baffles are arranged between the miniature steel pipe piles, meanwhile, PVC drainage pipes are arranged between the miniature steel pipe piles to drain out crack water of the dangerous rock mass, and gaps between the miniature steel pipe piles and thedangerous rock mass are backfilled with concrete, so that the dangerous rock mass at the lower portion makes full contact with the ground; and the dangerous rock mass at the upper portion is supported by matching lattice beams with pre-stressed anchor cables, covering soil is arranged in gaps between the lattice beams for backfilling, and grass seeds are planted in the covering soil for greeningdesign. According to the miniature pile and anchor cable combined supporting structure for treating dangerous rock mass and the construction method of the miniature pile and anchor cable combined supporting structure, due to the fact that the miniature piles are high in construction speed, development of dangerous rock mass deformation can be preliminarily controlled in a short time, and high efficiency is achieved.
本发明公开了一种治理危岩体的微型桩+锚索联合支护结构及其施工方法，该结构包括双排布置的微型钢管桩，所述微型钢管桩顶部设置桩顶冠梁，桩顶冠梁将双排桩连接起来使其整体协同受力；微型钢管桩之间设置预制混凝土挡板；同时在微型桩之间设置PVC排水管将危岩体裂隙水引排出来；微型钢管桩与危岩体之间的空隙采用混凝土进行回填处理，使下部危岩体与地面之间充分接触；上部危岩体通过框格梁搭配预应力锚索进行支护处理，对框格梁之间的空隙设置覆土回填，并在覆土中种植草籽进行绿化设计。本发明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。
