Description

Technical Field

[0001] The utility model relates to the technical field of ladders for pipe jacking wells, in particular to an assembled ladder device for pipe jacking wells. Background Art

[0002] A pipe jacking well is an engineering facility used for underground pipeline construction and maintenance. It is usually a circular wellhead located on the ground to provide access to the underground pipeline system. The main uses of pipe jacking wells include the following aspects:

[0003] 1. Pipeline installation and maintenance: Pipe jacking wells are important tools for installing and maintaining underground pipeline systems. During pipeline installation, construction workers can enter the underground through pipe jacking wells to connect and arrange pipelines. During pipeline maintenance, pipe jacking wells can provide access to the underground pipeline system to facilitate inspection and repair work;

[0004] 2. Pipeline inspection and cleaning: Pipeline jacking wells can also be used for pipeline inspection and cleaning. Through the pipe jacking well, workers can send inspection equipment and cleaning equipment into the underground pipeline system to inspect and clean the pipeline to ensure the normal operation of the pipeline;

[0005] 3. Drainage and sewage: Pipe jacking wells can also be used for drainage and sewage work. In urban drainage systems, pipe jacking wells are usually used to collect and discharge rainwater and sewage. Through pipe jacking wells, rainwater and sewage can be guided into the underground pipe system and then sent to treatment facilities for treatment;

[0006] 4. Ventilation and ventilation: Pipe jacking shafts can also be used to provide ventilation and ventilation of underground spaces. In underground piping systems, some harmful gases or odors may be generated due to the airtightness of the pipes. Through pipe jacking shafts, fresh air can be introduced into the underground space, and harmful gases and odors can be discharged to ensure the safety and comfort of the underground space.

Therefore, this application proposes an assembled ladder device for pipe jacking wells, which uses prefabricated standard modular steel ladders. After production, standard modules can be used to assemble independently according to the actual situation on site. Utility Model Content
