Study on continuous construction of Jinghong hydropower station RCC dam in high temperature;

The continuous construction of the Basecourse and the surface of the Lime-fly-ash Macadam is a new method that can accelerate the overall construction process, shorten the time limit for the project and further develop new characteristics of the Lime-fly-ash material.

Using cement hydration mechanism and gradation composition principle,design methods of anti-cracks base were put forward with expansive cement and skeleton and dense structure gradation;technologies of continuous construction of two layers and saw cracks in advance were used.

Analysis of the mechanical effect on rapid construction of super-long soft surrounding rock tunnel with high water content;

Concrete quick construction for shifting the temporary ship-lock to silt sluice in the Three Gorges Project;

Futhermore,the experiences of quick construction of tunnel are accumulated.

Introduce quick construction technology of reinforced concrete oblong assembly culvert following “protecting permafrost soil” principle—winter construction.

Some other construction performances and experiences are introduced and an efficienty way of reaching a high quality and speedy construction in the baserock section of the vertical shafts are also discassed.

The speedy construction with borehole, longhole drilling and blasting method at the freezing baserock section in №2 mine of Xuandong has been introduced.
