在充分考虑当前双连拱隧道中隔墙的施工复杂性、渗漏水易发性及其结构特征的基础上,将现有整体浇筑成型的中隔墙采用模块化生产、模块化施工完成,提出了一种双连拱隧道模块化防排水中隔墙结构及其设计方法。模块化防排水中隔墙的结构包括:中隔墙下部现浇模块和连接在中隔墙下部现浇模块顶部的多个相互连接的中隔墙上部Y形预制模块,以及由防排水板、排水管和沉淀井共同构成的中隔墙防排水系统,其中中隔墙上部Y形预制模块与双连拱隧道拱顶二次衬砌连接。模块化防排水中隔墙施工包括多个中隔墙上部Y形预制模块施工、中隔墙下部现浇模块施工及中隔墙上下部的连接与整体成型。
Based on full consideration of the construction complexity of the partition wall in the double-arch tunnel, the vulnerability of the seepage water and the structural features of the double-arch tunnel, the existing integral partition wall is molded in a modular manner and the modular construction is completed. A double-arch tunnel modular waterproofing partition wall structure and its design method. The structure of the modular water-proof partition wall includes: a middle partition wall lower cast-in module and a plurality of interconnected middle partition upper wall Y-shaped prefabricated modules connected to the top of the cast-in-place module at the lower part of the middle partition wall, Drainage and sedimentation wells together constitute the wall of the drainage system, in which the upper wall of the Y-shaped prefabricated modules and double arch tunnel secondary lining connection. Modular waterproofing in the construction of the wall includes a number of middle partition wall Y-shaped precast module construction, the lower part of the wall cast-in-place module construction and the upper and lower partition wall connection and the overall shape.
