| 2. | In conclusion . it is viable and significant to use calcium carbide dust instead of lime 总之,用电石灰来替代石灰是可行的,而且具有现实的重要意义。 |
| 3. | Application of calcium carbide dust . 5 . proposal about road way structure of cangzhou 经研究分析发现,电石灰的主要成分是氢氧化钙,而石灰的主要成分也是氢氧化钙。 |
| 4. | We analyse a mass of data of experiments and conclude that calcium carbide dust can be used in place of lime completely 经过室内的大量试验和试验路的试验数据分析,电石灰完全可以替代石灰。 |
| 5. | Cangzhou is a chemical engineering city . calcium carbide dust is a sort of indutrial solid wastes discharged from chemical industry 沧州是一座化工城市,电石灰是其化工行业排放的一种工业废渣。 |
| 6. | About mixture rate of calcium carbide dust stabilization and calcium carbide dust s mixing dose , controlling methodand construct technics , we conduct large number of indoor tests and outdoor tests and educe scientific datas and methods 对于电石灰稳定土、电石灰二灰土和电石灰二灰稳定级配碎石的配合比以及电石灰的掺和剂量、控制方法、施工操作工艺等都做了大量的室内、室外试验,得出比较科学的数据和方法。 |
| 7. | We can use both calcium carbide dust and calcium carbide dust - flyash to stabilize fine - soil . as well as being used in subbase of high grade road , calcium carbide dust stabilization and calcium carbide dust - flyash stabilization can be used in basecourse of low grade road . so we can deduce that calcium carbide dust - flyash - gravel stabilization can be used in basecourse of high grade road 我们可以利用电石灰来稳定细粒土,利用电石灰和粉煤灰来稳定细粒土。通过数据分析,这种电石灰稳定土和电石灰二灰土完全可以刚于高等级公路的高级路面的底基层,也可以用于低等级公路的路面基层,同时推断,用电石灰和粉煤灰来稳定的级配碎石,可用于高等级公路的路面基层。 |
| 8. | Calcium carbide dust pollutes environment seriously and in addition , the question of storage restricted the development of the corporation . to settle the question about calcium carbide dust is imperative under the situations . the text expatiated the application of calcium carbide ash in highway building . the article includes five aspects : 1 . application of lime soil 本文主要阐述电石灰在公路工程中的应用,为说明问题,全文共分五个部分,即一、石灰土在公路工程中的应用;二、二灰土的应用;三、石灰粉煤灰稳定级配碎石;四、电石灰应用;五、对沧州地区柔性路面结构组合的建议。 |
| 9. | Cleanup corrosive substance in pipe such as internal water , clean oil , methane hydrate , ferric oxide , carbide dust , carbon bisulfide , hydrosulphurice acide , etc . ; reduce corrosion damages to inner wall of pipeline caused by corrosive substance ; clarify pipe route again ; inspect pipe deformation ; check perfectness ratio of valves along pipe ; decrease working backpressure 清除管线内部积水、轻质油、甲烷水合物、氧化铁、碳化物粉尘、二硫化碳、氢硫酸等腐蚀性物质;降低腐蚀性物质对管道内壁的腐蚀损伤;重新明确管线走向;检测管线变形;检查沿线阀门完好率;减小工作回压。 |
| 10. | By studing and analyzing , we can discover that calcium carbide dust and lime have the same primary component - ca ( oh ) 2 . if we can use calcium carbide dust instead of lime as the base material in road construction , not only solve the question of environment pollution , but also bright great vital force to the chemical industry of cangzhou . at the same time , it can reduce engineering cost . therefore , using calcium carbide dust have both economical benefit and social benefit 如果利用电石灰来替代石灰应用于公路工程中,不仅解决了当地的因“废”之忧,给沧州一片净土,也给沧州的化工行业带来了生机,同时,用电石灰代替石灰,大大降低了工程成本。因此,在公路工程中利用电石灰不仅具有明显的经济效益,还有更为显著的社会效益和环境效益。 |
