Submarine immersed tunnel post-cast strip construction method
The invention relates to the technical field of immersed tunnel construction, in particular to a submarine immersed tunnel post-cast strip construction method. Comprising the steps of structure installation before construction of the post-cast strip, secondary water stopping of the post-cast strip of the immersed tube tunnel, through measurement of the post-cast strip of the immersed tube tunnel, steel bar binding of the post-cast strip, formwork erecting of the post-cast strip, concrete pouring of the post-cast strip and waterproof measures of the post-cast strip. According to the construction method, the construction of the immersed tunnel post-cast strip is completed by adopting the complete and detailed construction process of undersea jacking post-cast, and through the post-cast strip structure system, the problems that the underwater butt joint operation amount of a traditional undersea immersed tunnel is large, the efficiency is low, the risk is large, transportation and hoisting operation is needed, and the butt joint precision control difficulty is large are solved. Through research on the construction process of the immersed tunnel post-cast strip, the control difficulty of butt joint installation of the immersed tunnel is greatly simplified, and quality control and construction efficiency are greatly guaranteed through post-cast strip structure concrete cast-in-place.
本发明涉及沉管隧道施工技术领域，具体涉及一种海底沉管隧道后浇带施工方法。包括后浇带施工前结构安装、沉管隧道后浇带二次止水、沉管隧道后浇带贯通测量、后浇带钢筋绑扎、后浇带模板支立、后浇带混凝土浇筑、后浇带防水措施。本发明采用完整详尽的整套海下顶进后浇的施工过程完成沉管隧道后浇带的施工，通过后浇带结构体系，优化了传统海底沉管隧道水下对接作业量大、效率低、风险大、需要运输吊装操作，对接精度控制难度大等问题。通过沉管隧道后浇带的施工过程的研究，大大简化了沉管隧道对接安装的控制难度，且后浇带结构混凝土现浇对于质量控制，施工效率也有极大的保证。
