【正文】 工導(dǎo)流，基礎(chǔ)處理 Abstract The Lingjiang Hydrojunction Projects are at I level and located on the Lingjiang River. 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 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. Key words: hydraulic engineering construction, the construction diversion, foundation treatment 前 言 為使我們能把理論聯(lián)系實(shí)際，加深對(duì)所學(xué)知識(shí)的理解和掌握，為正式踏上工作崗位投入實(shí)際水利工程的規(guī)劃，勘測，設(shè)計(jì)，施工等。 裝機(jī)容量 90 萬千瓦（ 6 15 萬千瓦），它是一項(xiàng)具有防洪、發(fā)電、灌溉、航運(yùn)和養(yǎng)殖等綜合效益的改革大自然的偉大工程。 水利工程施工是一門涉及面較廣、學(xué)術(shù)性較強(qiáng)、內(nèi)容組織結(jié)構(gòu)聯(lián)系較緊密的學(xué)科。 編者 李 坡 目 錄 1 工程概況 ................................................................................................................................... 1 樞紐地理概況 ..................................................................................................................... 1 工場地及運(yùn)輸條件 ....................................................................................................... 1 水文氣象 .............................................................................................................................. 1 水文 ............................................................................................................................... 1 氣象 ............................................................................................................................... 2 工程地質(zhì)及水文地質(zhì) .......................................................................................................... 4 當(dāng)?shù)亟ㄖ牧? ...................................................................................................................... 5 砂礫石料 ....................................................................................................................... 5 粘性土料 ....................................................................................................................... 6 塊石料 ........................................................................................................................... 6 木材 ............................................................................................................................... 6 . 工程量 .......................................................................................................................... 6 2 施工導(dǎo)流設(shè)計(jì) ........................................................................................................................... 9 導(dǎo)流方式選擇和導(dǎo)流時(shí)段劃分 .......................................................................................... 9 導(dǎo)流方式選擇 ............................................................................................................... 9 導(dǎo)流時(shí)段的劃分 ......................................................................................................... 10 導(dǎo)流設(shè)計(jì)標(biāo)準(zhǔn)和導(dǎo)流設(shè)計(jì)流量 ........................................................................................ 10 導(dǎo)流 設(shè)計(jì)標(biāo)準(zhǔn) ............................................................................................................. 10 導(dǎo)流設(shè)計(jì)流量 ............................................................................................................. 12 導(dǎo)流方案的擬定 ................................................................................................................ 12 圍堰堰頂高程的確定 ........................................................................................................ 13 .................................................................................................. 14 二期圍堰高程的確定 .................................................................................................. 17 3 導(dǎo)流建筑物設(shè)計(jì) .....................................
