The invention discloses a connecting structure of shield precast segments. The connecting structure of the shield precast segments comprises an upper precast segment and a lower precast segment, wherein an upper overlapping part arranged to be close to the outer surface of the upper precast segment is arranged at the tail end, close to the lower precast segment, of the upper precast segment, and the position, corresponding to the upper overlapping part, of the lower precast segment is provided with a lower overlapping part; meanwhile, a connecting and adjusting sheet is arranged between the upper precast segment and the lower precast segment; the connecting and adjusting sheet is made of cuttable materials, and comprises a connecting shell body and a penetrating connecting cavity body, and meanwhile a plurality of U-shaped connecting grooves are formed in the inner and outer surfaces, corresponding to the upper precast segment and the lower precast segment, of the connecting shell body; the upper precast segment and the lower precast segment penetrate through the U-shaped connecting grooves of the corresponding connecting and adjusting sheet through a plurality of connecting bolts correspondingly; and one of the ends, in the direction of the U-shaped connecting grooves, of the connecting and adjusting sheet can be cut. The connecting structure of the shield precast segments solves the problem of mounting gaps of shield precast segments, and is convenient and rapid to mount.
Description
technical field [0001] The invention relates to the technical field of shield tunneling prefabricated segments, in particular to a shield tunneling prefabricated segment connection structure. Background technique [0002] The shield segment is the main assembly component of shield construction and the innermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. [0003] The shield construction method has become the preferred construction method for interval tunnels in the rail transit field, and this construction method is also widely used in the fields of roads, hydraulic engineering and railways. [0004] In the subway construction, the shield prefabricated segment...
