1 概述
三峽工程大壩為混凝土重力壩，最大壩高181m，樞紐工程混凝土澆筑總量達2800萬m3。如此巨大的混凝土工程施工總量，導致了三峽工程混凝土施工澆筑的高強度施工。
1.1 混凝土施工強度
三峽工程混凝土澆筑高峰集中在第二階段工程，其混凝土澆筑總量達1860萬m3。根據(jù)施工進展及總進度的安排，1998年為118萬m3，1999年為458萬m3，2000年為548萬m3，2001年為403萬m3，2002年計劃完成142萬m3。施工高峰時段主要集中在1999～2001年三年間，其中，以2000年的混凝土澆筑強度為最高，要求年最高澆筑量達到500萬m3，月最高達到40萬m3，日最高達到2.0萬m3以上。
1.2 混凝土施工手段
根據(jù)對澆筑強度和施工場地分析，采用傳統(tǒng)的門塔機澆筑施工手段是不能滿足澆筑強度要求的，必須尋找新型高強度的澆筑手段。
另外，大型門塔機澆筑方案從拌和樓出機口到澆筑倉，均采取間歇式給料方式，供料的中轉環(huán)節(jié)多，供料效率低下，多座拌和樓與多座門塔機再與多個澆筑倉之間生產組合錯綜復雜，易于錯料，更增加了施工管理的難度......
Concrete construction of the Three Gorges Dam scheme and process analysis
1 Overview
Three Gorges dam is concrete gravity dam, the maximum height of 181m, concrete pouring Project reached a total of 28 million m3. Such a huge amount of concrete construction, concrete construction has led to the Three Gorges Project Construction pouring of high-intensity.
1.1 Concrete Strength
The peak concentration of the Three Gorges Project concrete placement in the second stage, the concrete pouring reached a total of 18.6 million m3. According to the general progress of the construction progress and the arrangements in 1998 to 1.18 million m3, 1999 year 4.58 million m3, 2000 year 5.48 million m3, 2001 year 4.03 million m3, 2002-year plan the completion of 1.42 million m3. The peak construction period focused on three-year period from 1999 to 2001, where in 2000 the highest strength of the concrete pouring, pouring reached the annual maximum demands 5 million m3, up to 400,000 on m3, up to date more than 20 000 m3.
1.2 concrete construction method
Based on the placement of the strength and construction site, using the traditional gate tower placement and construction methods can not meet the requirements of pouring strength, must find new means of high-strength casting.
In addition, the large gate tower placement scheme from Mixing machines exported to pouring out of position, were taken to intermittent feeding mode, feeding more than a transit link for the feed efficiency is low, more and more Block Mixing Block gate tower again production mix between the number of placement positions in complex material easy to mistake, but increased the difficulty of construction management ......
