Reservoir area diversion tunnel inlet rock plug blasting construction method
The reservoir area diversion tunnel inlet rock plug blasting construction method is suitable for the technical field of water conservancy and hydropower engineering and comprises the following steps that S1, a rock plug opening is pretreated before construction; s2, the position of a slag collecting net is selected, and the slag collecting net is arranged; s3, a gate of the gate shaft is closed, and a flexible damping device is installed; and S4, blasting for several times and setting a water flow mode to clean rock ballast. The slag collecting net and the flexible damping device are arranged, meanwhile, water flow potential energy is used for cleaning rock ballast, the construction period is shortened in the aspects of blasting, slag collecting, slag cleaning and the like, construction is facilitated, and an existing building is protected; meanwhile, the stone ballast is cleaned in a multi-time blasting and water flow mode, the investment of the construction cost can be reduced, and due to improvement of blasting and cleaning efficiency, the construction period can be shortened, and the construction cost is further reduced.
本发明公开了一种库区引水洞进口岩塞爆破施工方法，适用于水利水电工程技术领域，包括以下步骤：S1、对岩塞口进行施工前预处理；S2、选择集渣网位置并设置集渣网；S3、将闸门井的闸门关闭并安装柔性减震装置；S4、分次爆破并设置水流模式清理石渣。通过设置集渣网和柔性减震装置，同时利用水流势能清理石渣，从爆破、集渣、清渣等方面实现缩短施工工期，便于施工，保护了已有建筑物；同时，通过分次爆破和水流模式清理石渣，可以减少施工成本的投入，由于爆破和清理效率的提高，可以缩短工期，进一步降低施工成本。
