Prefabricated assembly type arched open-cut tunnel superposed joint structure and construction method thereof
The invention relates to the field of tunnel construction, in particular to a prefabricated assembly type arched open-cut tunnel superposed joint structure and a construction method thereof. The prefabricated assembly type arched open-cut tunnel superposed joint structure comprises a tunnel segment, the tunnel segment comprises a prefabricated structure part and a plurality of U-shaped load-bearing steel bars, the prefabricated structure part is square, the free ends of the U-shaped load-bearing steel bars are poured and fixed in the prefabricated structure part, and the bent ends of the U-shaped load-bearing steel bars extend out of one side of the prefabricated structure part; the invention further relates to a method which comprises the following steps that S1, manufacturing of the tunnel segment is completed in the prefabricated factory building, the end of the tunnel segment is prefabricated into the inverted-T-shaped section, and the U-shaped steel bars serve as load-bearing steel bars to be embedded into the tunnel segment; s2, tunnel segments are transported to a site and spliced through a crane, U-shaped steel bars of prefabricated parts are arranged in a crossed mode, and after lap joint of inverted-T-shaped webs is completed, inclined bolts are added to be inserted into pre-buried sleeves; the waterproof performance of the tunnel segment joint can be improved.
本发明涉及隧道施工领域，特别涉及一种预制装配式拱形明挖隧道叠合接头结构及其施工方法。一种预制装配式拱形明挖隧道叠合接头结构：包括隧道管片，所述隧道管片包括：预制结构部和若干U型受力钢筋，所述预制结构部成方形，U型受力钢筋的自由端浇筑固定在预制结构部内，所述U型受力钢筋的弯曲端伸出预制结构部的一侧；还涉及一种方法，包括以下步骤：S1：在预制厂房中完成隧道管片的制作，将隧道管片的端头预制成倒T型截面，且将U型钢筋作为受力钢筋预埋至隧道管片中；S2：将隧道管片运输至现场，用吊机进行拼装，预制部分的U型钢筋采用交叉布置，在倒T型腹板完成搭接后，加斜螺栓插入预埋的套筒内；能够提升隧道管片接头处的防水性能。
