长期以来,人们浇注大体积混凝土工程,常常用尽了种种办法,结果仍免不了要设置许多施工缝,无法保证真正的整体性.直到七十年代,英国水泥和混凝土协会的专家才首创了一种适用于大体积钢筋混凝土工程的连续浇注法,并已进行过较多的工程实践,取得了良好的技术和经济效果.采用这个方法,就是浇成大如山丘的人造石头,也非难事,而且能保证达到“天衣无缝”般的整体性.

For a long time, people poured large volumes of concrete and often used various methods. As a result, many construction joints were still necessary. There was no guarantee of true integrity. Until the 1970s, the experts of the British Cement and Concrete Association pioneered a kind of construction. The continuous casting method is suitable for large-scale reinforced concrete works, and has been carried out more engineering practice, and has achieved good technical and economic results. It is not difficult to use this method to cast man-made stones that are as large as hills. Can guarantee to achieve a “seamless” integrity.
