文章介绍了20m后张法预应力空心板预制铺底混凝土顶板下料连续浇注施工质量控制工法。该工法通过采取对空心板芯模改良、改变模板安装与混凝土浇注施工的传统次序等措施,克服了20m后张法预应力空心板预制出现的混凝土浇注不连续,质量不易保证的不足,可供公路工程施工技术管理人员从事20m后张法预应力空心板预制时参考。
The article introduced the 20m post-tensioned prestressed hollow slab prefabricated concrete roof cutting continuous casting construction quality control method. The method overcomes the shortcomings of precast concrete hollowed-out 20m post-tensioned prefabricated concrete, which is not easy to guarantee the quality by taking measures to improve the hollow core die, to change the traditional order of template installation and concrete pouring construction, etc. Highway engineering and construction management personnel engaged in prefabricated 20m prestressed hollow slab reference time.
