Segmental prefabricated single-box single-chamber variable-height prestressed concrete box girder and construction method thereof
The invention relates to a segmental prefabricated single-box single-chamber variable-height prestressed concrete box girder and a construction method thereof. According to the scheme, the construction method comprises the steps that 1, embedded parts are installed; 2, a template of the zero block is installed; 3, a zero block is poured; 4, a support of the first block is installed; 5, mounting a bridge erecting machine; 6, the first block is in place; step 7, pouring a wet joint; and 8, other prefabricated sections are installed, specifically, except for the zero block and the first block, the remaining prefabricated sections are installed in the mode of simultaneous suspension and segmented connection, and construction is completed. According to the construction method, the construction mode of the zero block formwork system is innovated, and erection of a support is avoided; the first block is placed and installed through the supporting platform, and the installation precision and efficiency of the first block are improved; and the other prefabricated sections are suspended at the same time and connected at the same time, so that the assembly efficiency is improved.
本申请涉及节段预制单箱单室变高预应力混凝土箱梁及其施工方法，该方案包括：步骤1、安装预埋件；步骤2、安装零号块的模板；步骤3、浇筑零号块；步骤4、安装壹号块的支撑；步骤5、安装架桥机；步骤6、壹号块就位；步骤7、浇筑湿接缝；步骤8、安装其余预制节段：除零号块和壹号块外，剩余的预制节段的安装采用同时悬吊、分段连接的方式，以完成施工。本申请创新了零号块模板体系的构建方式，避免了支架搭设；利用支撑平台搁置并安装壹号块，提高了壹号块的安装精度与效率；其余预制节段采用同时悬吊、分段同时连接的方式，提高了拼装效率。
