郑州大学本科毕业论文题目:施工工地扬尘影响因素及抑尘措施研究指导教师:刘忠玉职称:教授学生姓名:赵洋学号:20110420529专业:土木工程院(系):土木工程完成时间:2015年5月19日摘要随着现代化进程得加快,空气污染问题越来越严重。在美国环境署得报告中出,空气污染92%来自扬尘,有23%来自建筑工地。可见,治理扬尘问题能有效得改善空气状况,提高人们生活质量得水平,降低呼吸道疾病得发病率,特别就是由粉尘引起得尘肺癌等。因此,本文对于建筑工地扬尘影响因素以及抑尘措施得研究具有十分深远重大得意义。本文将从建筑工地扬尘得产生开始,通过调查,分析,实验等措施,总结分析建筑工地中扬尘产生得影响因素,以及传统抑尘方法,对比分析各中优劣。并将在抑尘剂得选用过程中,对于某树脂类液体抑尘剂得抑尘效果以及抑尘效果得影响因素进行探究,并以比例为1:4得粉体盐类抑尘剂作为对比试验。试验结果表明,比例为1:4得粉体抑尘剂得抗高温保湿能力较差,且缺乏凝并与固结作用,但其抗风保湿能力较好;液体抑尘剂具有良好得凝并作用与固结作用,还具有一定得湿润作用;对液体抑尘剂来说,抑尘剂:水=1:20~1:30为合理配比。关键词:建筑工地,扬尘,抑尘剂,影响因素AbstractWiththemodernizationisspeedingupdeveloping,theproblemofairpollutionismoreandmoreserious、theEnvironmentAgency'sreportintheUnitedStatessaysthat,92%ofairpollutionfromdust,23%efromtheconstructionsite、Obviously,theproblemofdusteffectivelyimprovetheaircondition,raisethequality,ofpeople'slife、reducetheincidenceofrespiratorydiseases,especiallycausedbydustdustlungcancer,etc、Soweshouldstudytheinfluencingfactorsofdustanddustsuppressionmeasures、Itisnecessary、Inthispaper,wewillsummarizethemaininfluencingfactorsofdustproducedintheconstructionsiteandanalysistheadvantagesanddisadvantagesofthetraditionalmethodofdustsuppressionbyreadingliterature,fieldinginvestigation,、Toexplorearesintypeliquiddustsuppressionagentappliedtothefeasibilityoftheconstructionsite,theeffectofdustsuppressionandtheinfluencefactorsofthedustsuppressioneffectindoorsimulationexperimentresearch,witharatioof1:4powdersaltdustsuppressionagentasacontrasttest、Testresultsshowthattheratioof1:4powderdustsuppressionagentofpoorabilitytoresisthightemperatureandmoisture,andlackofcoagulationandconsolidationeffect,butitsabilitytoresistwindmoisturebetter;Testwithliquiddustsuppressionagenthasgoodcoagulationfunctionandconsolidationeffect,andalsohascertainwettingeffect;Forliquiddustsuppressionagent,dustsuppressionagent:water=1~isreasonableproportioning1:30、Keywords:constructionsitedustdustsuppressionagentinfluencingfactors目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc421030603"1绪论PAGEREF_Toc421030603\h
