DETAILED DESCRIPTION

[0021] The utility model will be described in detail in combination with specific implementation cases, and the following implementation cases will help the person skilled in the art to further understand the utility model, but do not limit the utility model in any form.

[0022] As Figure 1 — Figure 3As shown, this utility model relates to an asynchronous maintenance ladder suitable for steep slopes, including a concrete foundation and an asynchronous maintenance ladder set on the concrete foundation. The concrete foundation includes a walkway foundation 21 and a slope foundation 22. The asynchronous maintenance ladder includes a support column 14, on which a left main beam 11 and a right main beam 12 are inclinedly placed. A middle partition 13 is set between the left main beam 11 and the right main beam 12. A left step plate 31 is connected between the left main beam 11 and the middle partition 13, and a right step plate 32 is connected between the right main beam 12 and the middle partition 13. The support column 14 is fixedly connected to the slope foundation 22, and the bottom ends of the left main beam 11 and the right main beam 12 are fixedly connected to the walkway foundation 21.

[0023] The walkway foundation 21 and slope foundation 22 described in this solution are made of concrete, which is stable. During the pouring process, the embedded parts can be embedded in the concrete to effectively support the columns and asynchronous ladders. The left main beam 11 and right main beam 12 of the asynchronous maintenance ladder are each welded to the column 14. The bottom ends of the left main beam 11 and right main beam 12 are fixedly connected to the walkway foundation 21 to form multi-point support, which is solid and reliable as a whole. Furthermore, the width and spacing of the treads can be adjusted according to the slope, while ensuring that the treads are set horizontally, to adapt to the requirements of different steep slopes.

[0024] Once installed, this solution effectively increases tread width and reduces riser height, ensuring the safety of maintenance personnel during movement. It thus solves the problems of excessively narrow treads and excessively high risers on steep slopes, further enhancing safety.

[0025] Furthermore, the left step plate 31 and the right step plate 32 are staggered in height, that is, the left step plate 31 and the right step plate 32 are not synchronized, forming a height difference between the left and right sides, which increases the width of the tread surface and relatively reduces the height of the riser surface.

[0026] Furthermore, a walkway embedded part 23 is provided in the walkway foundation 21, and the bottom ends of the left main beam 11 and the right main beam 12 are welded to the walkway embedded part 23. A slope embedded part 24 is provided in the slope foundation 22, and the support column 14 is welded to the slope embedded part 24. The embedded parts are pre-set when the walkway foundation 21 and the slope foundation 22 are poured, which facilitates the connection. The connection is also made by welding, which ensures a reliable connection.

[0027] Furthermore, both the walkway embedded part 23 and the slope embedded part 24 are π-shaped, making connection convenient.

[0028] Furthermore, railing posts 41 are installed on the walkway foundation 21, the left main beam 11 and the right main beam 12, and handrails 42 are installed on the railing posts 41. With the handrails, the safety of construction personnel walking is further guaranteed.

[0029] During construction, the location for installing the ladder is determined based on the overall rock strata of the slope, and the excavation location of the slope foundation is calculated. The slope foundation surface is excavated during slope excavation, followed by the construction of the slope foundation concrete and embedded parts. Excavation continues to the walkway, where the base concrete is poured and embedded parts are installed. For asynchronous maintenance ladders, the columns and main beams are installed and welded first, followed by the installation of the left and right treads. All treads should be installed horizontally, with the inner edge of the lower step of the left tread coinciding with the projection line of the outer edge of the upper step. The left and right treads should be spaced out during installation, and the handrails are installed last.

[0030] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
