摘言:生料均化库是水泥企业熟料生产线一重要构筑物,其主要作用是对化学成分波动大的出料磨生料进行均化和储存,使入窑生料成分相对均齐、均匀,从而稳定大窑热工工效,提高大窑熟料产量并保证熟料质量。生料库多为筒体结构,其体量大、高度高,多采用滑模法施工,如何保证该重要构筑物实体质量,文章结合工程实践,从监理工作角度提出滑模施工中质量控制的方法及措施。 相似文献

清华大学的两层库房楼,因场地存在泥炭层厚薄悬殊,导致墙体发生大裂缝33条、成为危房,经重新勘察,查明系地基持力层普通存在软弱且厚度不均的有机土、泥炭层所致。比较多种加固方案后选用树根桩托换法,取得较好效果。 相似文献

The generation of coal ash by coal-fired thermal power plants has increased in recent years. This study focuses on the use of a type of coal ash, clinker ash, in place of sandy soil as a fill material in soil structures. Clinker ash is an excellent geomaterial to use as backfill for soil structures because it is lightweight and has high shear strength and permeability. In this study, to determine the applicability of clinker ash as a backfill material for steel strip-reinforced soil walls, a series of laboratory pullout tests was conducted on different types of clinker ash to investigate the pullout behaviour of a ribbed strip from a layer of clinker ash and to evaluate the influence of the overburden pressure and the degree of compaction on the maximum pullout resistance. The correlation between the physical properties of clinker ash and the maximum pullout resistance was investigated on the basis of the test results. Additionally, the results of the pullout tests were compared with those of in-situ pullout tests. Furthermore, the usefulness of clinker ash was evaluated by applying the pullout test results to the standard design method for reinforced soil walls and comparing the results with the material constants for commonly used sandy soil. The main conclusions of the study are as follows: (1) The tests performed here confirmed that clinker ash has excellent frictional properties compared with sandy soil. (2) The frictional properties of clinker ash exceed the proposed design values given in the manual describing the reinforced soil wall method. (3) The application of clinker ash in reinforced soil walls is effective from the viewpoint of frictional properties. 相似文献
