Protection and excavation method for steep mountains near existing roads
The invention discloses a protection and excavation method for steep mountains near existing roads. The method comprises the following steps that firstly, near roads are widened and rerouted for protection; then, GPS2 flexible active protection devices are pre-set up on the mountains of excavation sections of the near existing roads for pre-protection; then, SNS flexible passive protection devicesare adopted for double-layer pre-protection; and finally, the protected mountains are excavated in a layered and segmented mode in sequence from tops to bottoms and from insides to outsides, and whenexcavation is carried out at one working height each time, one passive protection device is dismantled till excavation is carried out at the designed elevation of the mountains. According to the method, the method is used for excavation construction of the steep mountains near the existing roads for bridges and roads, the safe operation of the roads can be guaranteed, the safety of surrounding residential buildings can be guaranteed, the damage range of excavation flying stones and mountain rolling stones can be effectively controlled, the construction is safe and reliable, compared with theprior art, the method is good in economical efficiency, and the method can be widely applied to excavation construction of the steep mountains near the existing roads for bridges and roads.
本发明公开了一种临近既有道路的陡峭山体防护及开挖方法，先对临近道路进行加宽改道防护，然后对临近既有道路开挖段山体预先搭设GPS2柔性主动防护装置预防护，再采用SNS柔性被动防护装置进行双层预防护，最后对防护后的山体采取由上到下、由内到外的顺序分层分段开挖，每开挖一个工作高度时，拆除一道被动防护装置，直至山体开挖至设计标高。本发明用于桥梁、道路的临近既有道路陡峭山体开挖施工，具有保证公路的安全运营，又能保护周边居民住宅的安全，且能有效控制开挖飞石及山体滚石的破坏范围，施工安全可靠，对比现有技术，经济性好，可广泛用于桥梁、道路的临近既有道路陡峭山体开挖施工作业中去。
