And the projects are posed of the power plant dam, the overflow dam, the overflow dam with big orifices, the overflow dam with deep orifices and the powerhouse behind dam. The installed capacity is about 900,000 kilowatts (615 ten thousand kilowatts), and it is an item with synthesis benefits, such as the flood prevention, electricity generation, irrigation, shipping and cultivation. It is called to be a great project for nature reform. This design includes the construction diversion and the design for foundation treatment. In the design, we have fully proven the key position terrain landform condition in the place analysis, the hydrology geology situation, and the meteorological data and so on. Considering the local construction condition, the rests on each kind of hydraulic engineering standard, we draw up the conduction current way that is to use the partition coffer dam law conduction current initially, and the conduction current time interval is perennial diversion. The conduction current standard is 20year frequency flood, according to the basic document. Through the quantitative terms and the conduction current plan economical parison, the programmer for diversion is embankment cofferdam, contracted river and the bottom orifice for releases. In the design, we use the rectangle diversion orifice in the diversion. In the construction, we determined the various types of construction machinery and the number by the calculation of works of the 華北水利水電學(xué)院畢業(yè)設(shè)計 III buildings. In the closure work design, we determined the different particle size and number of river materials the current situation through the river hydro calculation. In the reference pit drainage design, we determined the period’s drainage equipment through the displacement calculation in every period. In basic processing ponent, the use of blast by bore holes to excavate the dam foundation. Blasting parameters and the specific professional work are the main task in this design. To enhance the integrity of the dam foundation, and the bedrock bear, and increase the dense of the bedrock, and reduce leakage through the basic surface rock, we needed the consolidation grouting and the curtain grouting for the dam foundation. Because of the reasons above, this paper designed the layout and the basic parameters of the grouting.
