[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1:

[0020] As Figure 1 shown, a connecting passage transition construction system includes a plurality of sleepers 1 horizontally and spacedly arranged on tunnel segments, two H-shaped steels 2 longitudinally placed at both ends of the upper sides of a plurality of sleepers 1, an upper fixing channel steel 3 and a lower fixing channel steel 4 are arranged between the two H-shaped steels 2, a rail 5 is longitudinally arranged at the upper end of each H-shaped steel 2, and a support screw rod 7 is arranged between the H-shaped steel 2 and the tunnel segment 6.

[0021] A number of wooden wedges 8 are provided between the sleeper 1 and the bottom of the tunnel segment 6. The wooden wedges 8 create a suspended space between the sleeper 1 and the bottom of the tunnel segment 6. The freezing pipe 9 is arranged in the suspended space. The sleeper 1 and the tunnel segment 6 are fixed by post-inserted bars 10. The central points of the two H-shaped steels 2 are arranged directly below the rail bottom. The connection between the H-shaped steel 2 and the sleeper 1 is fixed by spikes 11. One end of the support screw rod 7 is arranged on the pipe wall, and the other end abuts against the H-shaped steel 2. A rubber cushion plate 12 is arranged between the rail 5 and the H-shaped steel 2. A pressing plate 13 is arranged between the rail 5 and the H-shaped steel 2.

[0022] The installation method of this application includes:

[0023] 1. Installation of the sleeper 1 and the H-shaped steel 2

[0024] 1) Installation of the sleeper 1

[0025] The sleeper 1 and the H-shaped steel 2 are transported to the designated location on site by a rail car. The sleeper 1 is carried to the connection passage manually. The sleepers 1 are installed on site at an interval of 4 m. The sleepers 1 are placed horizontally on the tunnel segment. The sleepers 1 are adjusted according to the on-site measurement points. The wooden wedges 8 are used to fill the suspended part between the sleeper 1 directly below the rail and the bottom of the segment, and the wooden wedges 8 are fixed by post-inserted bars 10. When there is no filling position below, the bridging support method is adopted for fixation. During the installation process, key control is carried out on the horizontal position and elevation of the sleeper 1.

[0026] After the installation of the sleeper 1 is completed, the sleeper 1 is fixed. The post-inserted bar method is adopted. A drill is used to drill holes on both sides of the square timber and post-inserted bars 10 are inserted. C18 threaded steel is used for the post-inserted bars, and each bar is 25 cm long. There are no less than 2 post-inserted bars on each side, and no less than 4 post-inserted bars for each square timber. The drilling depth is not less than 100 mm. After drilling, a blower is used to clean the holes and inject glue. The glue injection should be carried out evenly and slowly from the bottom of the hole outwards. Attention should be paid to exhausting the air in the hole. The amount of glue injection should be such that a little glue is extruded after the steel bar is inserted.

[0027] 2) Installation of the H-shaped steel

[0028] The installation position of the H-shaped steel 2 is directly below the rail bottom. The bottom presses against the top of the sleeper 1. The H-shaped steels 2 are installed on the sleeper 1 at an interval of 4 m along the line direction. The connection between the sleeper 1 and the H-shaped steel 2 is effectively fixed by spikes 11, with no less than 2 at each location. Horizontally, after fine adjustment is completed, 8# channel steels are used to reinforce the H-shaped steel 2 in upper and lower layers. The channel steels are cross-welded to the top of the upper layer and the bottom of the lower layer of the H-shaped steel 2 by welding. The H-shaped steel 2 is fixed by the support screw rod 7. One side of the support screw rod 7 is fixed on the pipe wall, and the other side abuts against the H-shaped steel 2.

[0029] 2. Installation of the rail

[0030] The steel rail 5 is transported to the construction site by a flatbed truck, and the steel rail 5 is installed on the H-shaped steel 2 using a subway gantry replacement laying machine. Before the installation of the steel rail 5, a rubber cushion plate 12 is placed under the rail bottom, and the gauge is roughly adjusted using a gauge. After the rough adjustment, one side of the pressing piece is welded to the I-beam and pressed against the rail bottom, and the other side is reserved and welded after the track is precisely adjusted.

[0031] Embodiment 2:

[0032] The same parts of this embodiment as those of Embodiment 1 will not be described again. The differences are as follows:

[0033] As Figure 2 shown,

[0034] The support screw 7 includes a threaded sleeve 71, threaded rods 72 sleeved on both sides of the threaded sleeve 71. Fixing blocks 73 are respectively provided at both ends of the threaded rods 72, and the two fixing blocks 73 are respectively connected to the H-shaped steel 2 and the tunnel segment 6. A through hole 74 is provided on the threaded sleeve 71, and the through hole 74 is used to rotate the threaded sleeve 71. When rotating, a steel bar or a steel pipe is inserted into the through hole to rotate the threaded sleeve, realizing the telescoping of the support screw.
