Fabricated open cut tunnel joint and construction method thereof
The invention relates to the field of tunnel construction, in particular to an assembly type open cut tunnel connector which comprises at least two spliced tunnel segments, each tunnel segment comprises a prefabricated pipe body, the bottom of each prefabricated pipe body extends towards the side face to form a protruding inverted-T-shaped section, and the inverted-T-shaped sections are lower than the prefabricated pipe bodies; an L-shaped cross section is fixed in the middle of the inverted T-shaped cross section, and a plurality of U-shaped load-bearing steel bars are further included; the construction method is characterized by comprising the following steps that S1, the tunnel segments are prefabricated, the U-shaped load-bearing steel bars are embedded into the tunnel segments, and the inverted-T-shaped sections are prefabricated at the joints of the tunnel segments; one end of the U-shaped load-bearing steel bar is poured in the prefabricated pipe body, and the other end of the U-shaped load-bearing steel bar is poured in the inverted-T-shaped section. S2, bolt holes are formed in the bottoms of the inverted-T-shaped sections, two matched tunnel segments are spliced, and after splicing is completed, bolt fixing is conducted through the bolt holes; and the assembling difficulty of the tunnel segments is reduced.
本发明涉及隧道施工领域，特别涉及一种装配式明挖隧道接头，包括至少两块拼接的隧道管片，所述隧道管片包括预制管体，预制管体的底部朝侧面延伸出突出倒T型截面，所述倒T型截面的高度低于预制管体的高度，所述倒T型截面中部固定有L型截面，还包括若干U型受力钢筋；还涉及一种装配式明挖隧道接头的施工方法，其特征在于：包括以下步骤：S1：预制隧道管片，将U型受力钢筋预埋入隧道管片中，隧道管片的接头处预制成倒T型截面；U型受力钢筋的一端浇筑在预制管体中，另一端浇筑在倒T型截面内。S2：倒T型截面底部开设螺栓孔，将两块配合的隧道管片进行拼接，拼接完成后，通过螺栓孔进行螺栓固定；降低了隧道管片拼装难度。
