Example Embodiment
[0037] Example 1:
[0038] Such as figure 1 What is shown is a cut surface structure of a single-track rail transit beam with built-in U-shaped rail support, including an outer U-shaped beam body 1 and a U-shaped rail support 2a placed in the beam body 1. Among them, the bottom of the U-shaped track support 2a is connected to the bottom of the beam body 1 as a whole, and the whole adopts a prestressed reinforced concrete structure.
[0039] In addition, the two arms of the beam body 1 are two wing panels, and wing edges 4 are provided on the top of the wing panels, and a number of fourth embedded nuts 41 for installing sound barriers are arranged outside the top surface of the wing edges 4 . Among them, the outer width of the top surface of the wing edge 4 should not be less than 800mm to facilitate the installation of equipment such as signal and sound barriers.
[0040] A number of first embedded nuts 11 for installing cables 7 are provided on the inner side wall of the beam body...
Example Embodiment
[0053] Example 2:
[0054] Such as Image 6 As shown in the figure, another implementation structure of this solution is to change the structure of the U-shaped rail support 2a in Embodiment 1 to the Π-shaped rail support 2b, and the other parts remain unchanged. After this change, the advantage is that the maglev plate 6 can be directly installed on the two ends of the Π-shaped rail support 2b, so that steel sleepers can be omitted, thereby further reducing the total investment cost of maglev rail transportation.
[0055] Among them, the cross-section structure of the dual-track rail transit beam with built-in Π-shaped track support, such as Figure 7 As shown, two double-track rail transit beams supported by built-in Π-shaped rails are arranged side by side on the bridge pier 10, and in the middle part, the two wing edges 4 are spliced together to directly form an emergency evacuation channel 9.
