DETAILED DESCRIPTION Specific embodiment 1:

[0025] See also Figures 1 to 3 As shown, a prefabricated escape ladder for underpass tunnel comprises an underpass tunnel 1, an escape ladder 2, a sliding fence 3, and a controller. The tunnel entrance of the underpass tunnel 1 is provided with an escape ladder 2, and the escape ladder 2 is a foldable ladder, which is convenient for folding and fixing at ordinary times to avoid blocking the road. The upper end of the escape ladder 2 extends to the ground road, and the side wall of the underpass tunnel 1 is provided with a folding groove 4, and the escape ladder 2 is folded in the folding groove 4. The upper end of the folding groove 4 is provided with a positioning lock 5, and the positioning lock 5 is a positioning pin or a rotating clamp ring. The positioning lock 5 is connected to a driving mechanism, and the driving mechanism is used to drive the positioning lock to achieve locking or unlocking of the escape ladder. The lower end of the folding groove 4 is provided with a limit block 6, and the limit block 6 is a rubber pad. The limit block 6 limits the distance of the escape ladder sliding down. The upper end of the escape ladder 2 is provided with a positioning block 7 extending to both sides, and the positioning lock 5 cooperates with the positioning block 7 to movably fix and lock the escape ladder in the folding groove. The lower end of the escape ladder is provided with a buffer rubber pad 10 to prevent the escape ladder from violently colliding with the ground during the sliding process, thereby protecting the escape ladder. In this specific embodiment: the escape ladder 2 is composed of a first escape ladder 2-1 and a second escape ladder 2-2 in two upper and lower sections, the second escape ladder 2-2 is located at the upper end, and an intermediate rest platform 9 is provided between the first escape ladder 2-1 and the second escape ladder 2-2. The second escape ladder 2-2 is parallel to the folding groove, and the first escape ladder 2-1 is folded in the folding groove. The positioning lock adopts a rotating clamp ring, and the driving mechanism adopts a motor. The driving mechanism is connected to the controller, and the rotating clamp ring is driven to rotate by the driving mechanism, so that the rotating clamp ring rotates and clamps the positioning block, thereby locking the first escape ladder 2-1; when the driving mechanism drives the rotating clamp ring to loosen the positioning block, the first escape ladder 2-1 automatically slides down to the limit block, so that it is convenient for people to quickly reach the road surface on both sides of the tunnel through the first escape ladder 2-1 and the second escape ladder 2-2. A temporary resting platform 11 is also provided at the upper end of the second escape ladder 2-2, so that personnel can take a short rest after climbing.

[0026] The road fence on both sides of the tunnel entrance is provided with a slide rail and a sliding fence 3 that slides with the slide rail. The sliding fence 3 is located directly above the escape ladder. The sliding fence 3 is connected to a controller. The controller controls the sliding fence 3 to slide on the slide rail to open an opening on the road fence, so that people can reach the ground road through the opening. The controller is set at the tunnel entrance, and the controller is set at a height of 1.5 meters at the tunnel entrance, so that people can control the escape ladder to automatically unlock through the controller, and the first escape ladder slides down to the ground.

[0027] Possibly, an emergency safety cabinet is also provided, in which the controller is arranged, and a striking hammer is arranged next to the emergency safety cabinet to prevent malicious human activation of the escape ladder through the controller in non-emergency situations.

[0028] Possibly, the controller is provided with a wireless network, and the wireless network is used to communicate with the road monitoring center 12, and control information is sent to the controller through the road monitoring center, so as to control the unlocking of the escape ladder and the action of the sliding fence.

[0029] Possibly, a rain gauge 8 is further provided at the tunnel entrance of the underpass, and the rain gauge 8 is electrically connected to the controller. The rainfall is monitored by the rain gauge 8 and sent to the controller. The controller automatically starts the driving mechanism to unlock the escape ladder and open the sliding fence according to the preset rainfall, thereby improving the degree of intelligence.
