Gate-type cable bent tower construction method
The invention discloses a gate-type cable bent tower construction method. The gate-type cable bent tower construction method comprises the following steps that S1, a tower column is subjected to section division; s2, a bearing platform and a tower column head section are constructed; s3, a creeping formwork is installed; s4, upwards constructing a plurality of sections and concrete buttresses of the tower column; s5, mounting a climbing formwork on the inner side surface of the tower column, upwards constructing a plurality of sections of the tower column again, and erecting a capping support; s6, after the crawling rail is subjected to step-crossing angle adjustment, a plurality of sections of the tower column continue to be constructed upwards; s7, a plurality of sections of the tower column continue to be constructed upwards, and a capping support is erected; s8, after the crawling rail is subjected to step-passing angle adjustment, a plurality of sections of the tower column continue to be constructed, and a cross beam pi-shaped support is installed; s9, the remaining tower column sections are constructed, and construction of the tower columns and the cross beams is completed; and S10, cable bent tower construction is completed. According to the construction method, the technical problem that an existing mature construction scheme cannot be used in actual construction is solved, new design is conducted in all construction stages, and bridge cable bent tower construction supported by the method is smoothly completed.
本发明公开了一种门式索塔施工方法，包括如下步骤：S1：塔柱进行节段划分；S2：施工承台及塔柱首节段；S3：安装爬模；S4：向上施工塔柱数个节段及砼支墩；S5：安装塔柱内侧面爬模，再次向上施工塔柱数个节段，并搭设封顶支架；S6：爬行轨先进行过台阶角度调整后，继续向上施工塔柱数个节段；S7：继续向上施工塔柱数个节段，并搭设封顶支架；S8：爬行轨先进行过台阶角度调整后，继续施工塔柱数个节段，并安装横梁π型支架；S9：施工剩余的塔柱节段，完成塔柱及横梁的施工；S10：索塔施工完成。本发明的施工方法解决了实际施工中无法使用现有成熟的施工方案的技术问题，在各个施工阶段均进行了新的设计，顺利完成了本申请依托的大桥索塔施工。
