随着热电工业的发展,粉煤灰的数量也日益增加,如何利用粉煤灰成了能源建设中的研究课题之一。本文介绍的两灰桩就是用粉煤灰与石灰按一定比例混合,振动挤密而成的。 为探索加固粉煤灰作为建筑物地基的可能性,笔者在江苏省电力设计院的配合下,与南通基础公司于1987年5-10月,在天生港电厂5~#灰池进行了以下一些现场试验:①粉煤灰与石灰配合比试验,本次试验选用石灰与粉煤灰体积比为1:5和1:9两种;②现场加固前后粉煤
With the development of thermal power industry, the amount of fly ash is also increasing. How to use fly ash has become one of the research topics in energy construction. The two ash piles described in this paper are mixed with fly ash and lime in a certain proportion and vibrated. In order to explore the possibility of reinforcing fly ash as a building foundation, the author worked with the Jiangsu Provincial Electric Power Design Institute, and conducted the following in the 5~# gray pool of Tianshenggang Power Plant in May and May 1987 with Nantong Basic Company. Field test: 1 fly ash and lime mix ratio test, this test uses lime and fly ash volume ratio of 1:5 and 1:9; 2 before and after site reinforcement pulverized coal
