一种拼装式钢筋混凝土边沟结构及应用初探
|
摘要
为了避免目前公路工程建设中所使用的整体式预制边沟、浆砌片石边沟、现浇混凝土边沟在施工过程中容易受到挤压破坏的情况以及边沟附近路面压实度不合格的情况,笔者根据同步施工碾压的概念,通过水工计算等分析研究,提出了一种拼装式钢筋混凝土边沟结构形式及其技术方案,质量符合现行标准与规范要求。将其应用于工程实践,工程进度比原工期缩短了2/3,边沟附近路面压实度达到了工程质量设计要求,方法简单可行,易于工程推广。
Integral prefabricated side ditch, mortar rubble side ditch and cast-in-place concrete side ditch is easy to be crushed and damaged, and the pavement compactness near the ditch is unqualified in highway engineering construction. To avoid these problems, through the analysis and research, the concept of synchronous construction and a assembled reinforced concrete side trench structure and technical scheme are proposed, and the quality conforms to the requirements of current regulations. And it is applied to engineering practice, which is 2/3 shorter than the original construction period, and the pavement compactness near the side ditch meets the design requirements. The method is simple, feasible and easy to be promoted.
