Erecting method and dismantling method of bridge support
The invention provides an erecting method of a bridge support. The erecting method specifically comprises the following steps that S1, construction preparation of an over-crossing existing line is conducted; s2, constructing a cast-in-place support strip-shaped foundation and a manual hole digging pile; s3, steel pipe stand columns are installed; s4, installing a double-spliced I-shaped steel cross beam; s5, assembling and hoisting the Bailey beams in groups; s6, a distribution beam is installed, and the elevation of a bottom die is adjusted; s7, prepressing the support; and S8, constructing a cast-in-place beam body. According to the erecting method of the bridge support, the steel pipe stand columns are used for supporting the single-layer bailey beams to serve as a cast-in-place support main beam stress structure, the steel pipe stand column foundation is a strip-shaped foundation in the section with the gentle terrain, and the hole pile foundation is manually dug in the section where the roadbed slope is prone to collapsing and the main span section; a protective shed frame is arranged above the existing line to prevent objects from falling in the construction process. A bamboo plywood and square wood formwork system which is easy to disassemble and light is adopted, and a tower crane serves as main hoisting equipment in the construction process.
本申请提供了一种桥梁支架的搭设方法，具体包括以下步骤：S1、上跨既有线施工准备；S2、现浇支架条形基础及人工挖孔桩施工；S3、安装钢管立柱；S4、安装双拼工字钢横梁；S5、贝雷梁分组拼装、吊装；S6、分配梁安装及底模标高调整；S7、支架预压；S8、现浇梁体施工。本申请提供的桥梁支架的搭设方法，利用钢管立柱支撑单层贝雷梁作为现浇支架主梁受力结构，钢管立柱基础在场地形较平缓地段采用条形基础，在路基边坡易垮塌和主跨地段人工挖孔桩基础，在既有线上方设防护棚架以防施工过程中坠物。采用易拆卸、轻便的竹胶板和方楞木模板系统，以塔式起重机为施工过程中的主要吊装设备。
