Super-huge type dangerous rock treatment construction method
The invention provides a super-huge type dangerous rock treatment construction method. The super-huge type dangerous rock treatment construction method comprises the steps that an entrance road is arranged at the top of a dangerous rock body, excavation construction is conducted on the dangerous rock body layer by layer from top to bottom, construction equipment descends along with a constructionface, and an exit road is arranged after the construction face on the lowermost layer is completed; the excavation construction specifically comprises the following steps that (1) a blasting vibrationspeed value of the dangerous rock body 20 m away from the outside of a blasting area is equal to 10 cm/s, and the maximum chemical preparation amount of a single-section hole is controlled; (2) a main blast hole, a buffer hole and a pre-splitting hole are drilled in the dangerous rock body and the mother rock, and explosive filling is carried out; (3) presplitting blasting operation is carried out along the designed profile surface of the excavated slope, and then blasting operation is carried out in the direction of being from the dangerous rock body to the mother rock; (4) blasting slag isexcavated layer by layer by an excavator; and (5) the excavated blasting slag is pushed to a lower aggregate platform. By the adoption of the method, the problems of construction arrangement, construction methods, construction procedures, construction equipment configuration, construction safety control and the like existing in extra-large dangerous rock construction are solved.
一种特大型危岩治理施工方法，危岩体顶部设置进场道路，危岩体由上向下逐层进行开挖施工，施工设备随施工面一同下降，在最下层施工面完成后设置出场道路；开挖施工具体包括以下步骤：1）以距离爆破区外20m处的危岩体爆破振动速度值=10cm/s为基准，进行单段孔最大制药量控制；2）在危岩体以及母岩上进行主爆破孔、缓冲孔和预裂孔的钻设作业，并进行炸药装填；3）沿开挖边坡设计轮廓面进行预裂爆破作业，然后由危岩体向母岩方向进行爆破作业；4）通过挖掘机逐层进行爆破渣料的开挖；5）开挖后的爆破渣料推料至下方集料平台。本发明采用上述方法，解决了特大危岩施工中存在的施工布置、施工方法、施工程序、施工设备配置、施工安全控制等问题。
