Large-cantilever T-structure reverse-construction cable-stayed construction method
The invention discloses a large-cantilever T-shaped structure inverse cable-stayed construction method, and relates to the technical field of bridge construction, and the technical scheme is that the method comprises the following steps: S1, pouring double thin-wall piers; s2, two webs of the pier top block are poured, and concrete is poured to the position below the longitudinal prestressed pipeline; s3, temporary connecting devices are arranged on the upper portions of the two web plates; s4, a bottom die platform is erected, the bottom die platform is connected with the web through a cable-stayed device, and the bottom die platform is connected with the cable-stayed device through a fastener; s5, a first layer of concrete is poured; s6, erecting a template and a prestressed steel beam pipeline in the beam box; s7, pouring a second layer of concrete; and S8, the bottom die platform, the cable-stayed device, the fastener and the inner template of the beam box are removed. The large cantilever T-shaped structure reverse construction support-free construction method has the beneficial effects that a support system is improved, and a support in the prior art is replaced more reasonably, safely and reliably through the cable-stayed device according to the large cantilever T-shaped structure reverse construction support-free construction method conducted through the cable-stayed device.
本发明公开了一种大悬臂T构逆作斜拉施工方法，涉及桥梁施工技术领域，技术方案为，包括以下步骤：S1、双薄壁墩浇筑；S2、墩顶块两块腹板浇筑，混凝土浇筑至纵向预应力管道的下方；S3、两块腹板的上部设置临时连接装置；S4、搭设底模平台，并将底模平台与腹板通过斜拉装置连接，底模平台与斜拉装置通过紧固件连接；S5、第一层混凝土浇筑；S6、梁箱内模板及预应力钢束管道搭设；S7、第二层混凝土浇筑；S8、底模平台、斜拉装置、紧固件及梁箱内模板拆除。本发明的有益效果是：本发明通过斜拉装置进行的大悬臂T构逆作无支架施工法，对支架体系的改进并通过斜拉装置对现有技术的支架进行更加合理、安全、可靠的替换。
