anti freeze meaning in English
防冻液
Examples
- But some difficult problems occurred , in construction due to shortage of system experiment on anti freeze of main canal lining project , it is very essential to carry out related experiment research for providing instruction of engineering practice and theory surppot of anti freeze of main canal lining project
但由于缺乏对干渠衬砌工程防冻胀的系统研究，在工程建设中出现了一些难点。为了指导工程实践，为灌区干渠防冻胀提供理论支撑，为进一步优化工程设计方案提供帮助，结合工程建设，进行防冻胀试验研究。 - The test obsvervation include air temperature , ground temperature , foundation moisture , freeze depth , freeze capicity , freeze residual capicity , groundwater table and shape transform of canal lining , etc . throught systemic observation , analysis of impact about each factor on fundation freeze capicity , evaluate effect on anti freeze of various canal lining , comparison on technology and ecnomic of different method , a kind of main canal lining format is been recommended to engineering practice with siutable to ningxia local feature , fufilling the need of main canal safey i application , economic and practical , that is using polystyrene plate laying under concrete slate and grit taking replace of filling layer and optimizing design
试验观测内容包括气温、地温、基土含水量、冻深、冻胀量、冻胀剩余量、地下水位和砌体外观变化等项目。通过系统的观测，分析各因素对基土冻胀量的影响，评价各种衬砌型式的防冻西安理工大学工程硕士专业学位论文胀效果，并进行技术和经济综合分析比较，推荐出了适合我区特点、满足干渠安全运行、经济实用、防冻胀效果好的干渠防渗衬砌型式，即混凝土板下铺设聚苯乙烯板和砂砾石换填层结构型式，加以优化设计，用于工程实践。
