Construction method for rapidly excavating underground plant of hydropower station
The invention discloses a construction method for rapidly excavating an underground plant of a hydropower station. The construction method comprises the following steps of: preparing in the early stage of construction, excavating a first ventilating shaft, excavating a first layer, excavating a second layer, entering a fifth layer of the underground plant from a bottom construction branch hole, excavating a fifth layer of pilot tunnel, excavating a second ventilating shaft, excavating a third layer, excavating a fourth layer, entering a sixth layer from a tail water connecting hole, excavating an elbow part, expanding and excavating the fifth layer, deslagging and trimming the sixth layer, and cleaning the bottom. The construction method for rapidly excavating the underground plant of the hydropower station is beneficial to shortening the construction period and improving the construction efficiency, is convenient for ventilation and deslagging, is high in overall safety coefficient, is timely in protection of each layer, and is suitable for popularization and use.
本发明公开了一种快速开挖水电站地下厂房的施工方法，包括如下步骤：施工前期准备、开挖第一通风竖井、第一层开挖、第二层开挖并由底部施工支洞进入地下厂房第五层，开挖第五层导洞、开挖第二通风竖井、第三层开挖、第四层开挖并由尾水连接洞进入第六层，开挖肘管部分、第五层扩挖、第六层出渣并修边、清底；该发明快速开挖水电站地下厂房的施工方法有利于缩短工期，提高施工效率，便于通风、排渣且整体安全系数高，各层防护及时，适合推广使用。
