[0035] A road slope maintenance pedestrian ladder with anti-skid and centralized water discharge functions, combined with Figure 1-Figure 4As shown, it includes steps 2, ladder belts 6, water barrier brow belts 1, anti-slip grooves 4 and drain grooves 5, wherein: the steps 2 are continuously arranged from the foot of the slope to the top of the slope, forming the main body of the pedestrian ladder, which meets the main function of the ladder for people to walk; the ladder belts 6 are continuously arranged from the foot of the slope to the top of the slope, and the slope is consistent with the slope of the road side slope, and are located on both sides of the step 2. The arrangement of the ladder belt 6 is relatively consistent with that of traditional stairs, and is used to improve the safety of the pedestrian ladder; the water barrier brow belt 1 is arranged above the ladder belt 6 and is higher than the step 2, and the two water barrier brow belts are respectively arranged on the step 2 The two outer sides of the step 2 form a downwardly concave trough, and the main body of the pedestrian ladder can also serve as a rapids trough for centralized water discharge; the anti-skid groove 4 is provided with at least 3 grooves along the longitudinal slope of the road, which are concave downward from the top surface of the step 2. The anti-skid groove 4 makes the top surface of the step 2 uneven, which can play an anti-skid effect; the drainage trough 5 is provided in the direction of the decreasing longitudinal slope of the road, which is concave downward from the top surface of the step 2 and runs through the top surface of the step 2, that is, it is provided along the length direction of the step 2, guiding the water flow from the step 2 at the top of the slope to the step 2 at the foot of the slope. The step 2, the water barrier brow 5 and the drainage trough 5 can all be cast in place with C20 concrete. This embodiment combines the water retaining brow belt 1 and the drainage groove 5 to guide the water flow along the step 2 from the top of the slope to the foot of the slope, accelerate the discharge of water on the step 2, prevent water accumulation, and avoid the step 2 from being wet for a long time after rain. At the same time, this embodiment is provided with an anti-skid groove 4 to reduce the possibility of maintenance personnel slipping when walking on the step 2. In this embodiment, the depth of the drainage groove 5 is set to 3 cm, and the height of the water retaining brow belt 1 is 6 cm.

[0036] Furthermore, the top surface of the step 2 is inclined downward from the side away from the drainage trough 5 to the side close to the drainage trough 5. Due to a certain inclination, water on each step 2 can flow from a high place to a low place, that is, flow toward the drainage trough 5, preventing water from accumulating on the step 2.

[0037] Furthermore, to ensure the safety and comfort of people walking on the step 2, the slope of the top surface of the step 2 from the side away from the drain trough 5 to the side close to the drain trough 5 is controlled to be 1-2%, and most preferably 1%.

[0038] Furthermore, similarly, the anti-skid groove 4 is tilted downward from a side away from the drain groove 5 to a side close to the drain groove 5, so that water in the anti-skid groove 4 can also flow to the drain groove 5 better to prevent water accumulation.

[0039] Furthermore, to ensure the safety and comfort of people walking on the step 2, the anti-slip groove 4 has a downward slope of 1-2% from the side away from the drain groove 5 to the side close to the drain groove 5, and is most preferably 1%.

[0040] Furthermore, since people usually step on the front edge of the step 2, that is, closer to the lower step 2, when walking on the stairs, the anti-skid groove 4 is arranged at the front edge of the step 2, which is more in line with people's behavior habits and can better play an anti-skid role. In this embodiment, the step is provided with 3 steps, each of which is 0.5 cm deep, with a center spacing of 3 cm, generally running through the width direction of the step 2 and ending at the drain groove 5.

[0041] Furthermore, the drainage trough 5 is inclined toward the slope foot, that is, downwardly inclined toward the slope foot, which can guide the water flow toward the slope foot more quickly, accelerate the discharge of water on the step 2, and prevent water accumulation.

[0042] Furthermore, the slope of the drain chute 5 towards the slope foot is 1-2%, and most preferably 1%.

[0043] Further, combined with Figure 1 , Figure 5 and Figure 6 As shown, it also includes a step handrail 7, which is arranged on one side of the step 2 and fixed on the ladder belt 6. The step handrail 7 is generally arranged on the side of the step 2 away from the drain trough 5, as shown in FIG. Figure 1 As shown in FIG, the drain trough 5 is arranged on the right side, and the step handrail 7 is arranged on the left side. The step handrail 7 is closer to the step 2 relative to the water barrier brow 1 on the same side. Figure 6 As shown, the step handrail 7 is embedded in the ladder belt 6, and the installation is more stable. The step handrail 7 is provided to facilitate the maintenance personnel to climb and better prevent the maintenance personnel from falling when walking on the step 2. The step handrail 7 can be made of aluminum alloy material, which has high strength, is not easy to deform, and can also prevent rust.

[0044] Further, it also includes anti-skid ear walls 3, which are arranged at intervals on the side of the ladder belt 6 and the step 2 facing the slope. The anti-skid ear walls 3 can be arranged every 1.5m-2.0m high, so that the pedestrian ladder fits the slope more firmly.

[0045] In addition, it needs to be further explained that the slope mentioned above refers to the ratio of height to horizontal distance, that is, the ratio of the two right-angled sides of a right triangle, which is the slope of the hypotenuse.
