一、永久工程 左岸8~#公路和砼生产系统已开挖至:8R0+280～340间1235～1215高程的台阶;8R0+400～500间1220～1212高程的台阶;8R0+655～720间1295～1245高程左右的便道;8R0+740左右1244高程的挡土墙砌筑;8R0+300～380间高程1238以上永久边坡的修整和部分危石及松散体的清理;并在1205高程便道上进行了相应的出渣工作。右岸7~#公路明挖段,在11月中旬在1291高程进行了放样,然后进行了预裂爆破,11月末进行了第1次爆破,爆破孔深12～15m,角度62°～65°。左坝肩开挖:通过厂房进水口的施工便道,在1150高程平台开挖了一部分属于坝肩的覆盖层,大面积开挖未开始。而且在左坝肩开挖的范围内,还有一部
First, permanent engineering Left bank 8 ~ # highway and concrete production system has been excavated to: 8R0 +280 ~ 340 1235 ~ 1215 elevation steps; 8R0 +400 ~ 500 1220 ~ 1212 elevation steps; 8R0 +655 ~ 720 1295 ~ 1245 about the height of the sidewalk; 8R0 + 740 about 1244 elevation retaining wall masonry; 8R0 +300 ~ 380 elevation above 1238 permanent slope trimming and some dangerous rock and loose body cleaning; and 1205 elevation On the corresponding slag work. Excavation of the 7 ~ # highway on the right bank was lofted in mid-November at an altitude of 1291, and then a presplitting blasting was carried out. At the end of November, the first blasting was carried out. The blasting hole depth was 12-15m and the angle was 62-65 °. Excavation of the left abutment: Through the construction access to the water inlet of the plant, a part of the cover belonging to the abutment is excavated on the 1150 elevation platform, and large-area excavation has not started. And in the scope of excavation of the left abutment, there is another one
