Description

Technical Field

[0001] The utility model relates to the field of inspection well construction, and particularly relates to a device for the construction of inspection well steps. Background Art

[0002] An inspection well is an important facility for managing underground facilities such as urban sewer pipes, water supply pipes, and cables. The main functions of an inspection well include providing an interface for accessing pipes or cables, facilitating inspection, cleaning, and maintenance work. The construction of inspection well steps is usually carried out after the casting of the wellbore. The inspection well wellbore, especially the sewage inspection well, is sometimes several meters deep, and the installation of ladders is extremely inconvenient; the construction of inspection well steps is an important process in inspection well construction. The construction of inspection well steps refers to setting steps around the inspection well so that operators can enter the well for inspection, maintenance, and repair work. The steps are usually installed on the walls around the wellhead or on the well wall to ensure that operators can enter and leave the well safely and conveniently.

[0003] During the construction of steps, operators often work inside the inspection well. Since the inside of the inspection well is relatively narrow and the working space is limited, when carrying out step construction at the construction site, a straight ladder or a self-made straight ladder is usually used as an operating platform. The construction workers stand on the treads of the straight ladder and use an impact drill to make holes at the designated positions, and then carry out the installation construction of the inspection well steps; the overall treads of the straight ladder are relatively narrow, and when the operators hold tools for operation, the treads will shake and be unstable, which not only affects the construction efficiency but also poses a great safety hazard.
