The construction results of expansion joints of road and bridge structures are directly related to the structural levelness and waterproofing ability of roads and bridges, and may even threaten the safety of vehicles driving on the road surface. Therefore, in the process of expansion joint construction in road and bridge projects,relevant technical personnel must formulate quality control strategies for expansion joint construction, choose high-performance construction materials, and purchase relatively advanced construction machinery and equipment to strictly control the construction quality results of expansion joints.
在我国水利工程建设中,为提高水利工程的整体防渗性能,施工单位须优化防渗处理工艺,选择合理的灌浆施工处理技术,有效增强水利工程的防渗处理效果.文章对水利工程防渗处理中的灌浆施工技术进行了详细分析,并提出处理过程中的技术要点.
低碳设计理念是我国实现绿色可持续发展的重要组成部分.从现阶段的城市化进程发展角度来看,建筑设计内涵正在不断完善,但当前部分项目在执行中仍然缺少低碳设计理念,导致周边环境受到了严重污染.为切实保证建筑设计的可靠性,文中对高层建筑设计中的低碳设计理念进行分析论述,并通过实践项目阐述相关内容,最后结合实际提出了策略.
通过正交试验研究了减水剂、保水剂、引气剂掺量对预拌砂浆表观密度、保水性及抗压强度的影响,结果表明:引气剂是影响表观密度和抗压强度的主要因素;保水剂是影响保水性的主要因素;当减水剂掺量为0.10‰,保水剂掺量为0.10‰,引气剂掺量为0.06‰时,砂浆性能指标最优.
