Full-prefabricated lane plate system of single-layer shield tunnel and construction method of full-prefabricated lane plate system
The invention discloses a full-prefabricated lane plate system of a single-layer shield tunnel and a construction method, the lane plate system comprises a shield segment, and wing mouth-shaped pieces are sequentially arranged in the shield segment along the length direction of the shield segment; post-cast strips are arranged on the two sides of each wing square piece respectively. The construction method comprises the steps that firstly, a plurality of winged square pieces are prefabricated, then the prefabricated winged square pieces are sequentially installed in the shield segment, and top plates of the adjacent winged square pieces are connected through connecting pieces; after the settlement of the tunnel is stable, post-pouring strips are poured on the two sides of each pouring strip wing mouth-shaped piece correspondingly; on the premise that the integrity of a lane plate system can be effectively guaranteed, the arrangement of a conventional cast-in-place bracket or an arc-shaped plate is omitted, and assembling construction is facilitated; rapid construction can be achieved, on-site workload can be reduced, the construction period is shortened, efficiency is improved, meanwhile, the requirement for splicing precision is relatively low, and interference caused by dislocation deformation of shield segments and internal structures is small.
本发明公开了单层盾构隧道全预制车道板体系及施工方法，车道板体系包括盾构管片，在所述盾构管片的内部并沿所述盾构管片的长度方向，依次设置有带翼口字件；每一所述带翼口字件的两侧分别设置有后浇带；施工方法包括首先预制若干带翼口字件，而后在盾构管片内依次安装预制完成的带翼口字件，若干相邻带翼口字件的顶板之间内通过连接件进行连接；待隧道沉降稳定后，在每一浇筑带翼口字件的两侧分别浇筑后浇带；本发明在能够有效保证车道板体系整体性的前提下，取消设置常规的现浇牛腿或弧形板，便于进行拼装施工；可实现快速施工并减少现场的工作量，从而缩短工期，提高效率，同时拼装精度要求相对较低，受盾构管片及内部结构错台变形干扰小。
