Description
Technical Field
The utility model relates to an inspection shaft operation appurtenance field specifically relates to a protection network device when being used for inspection shaft manual work.
Background
Inspection wells, named sand wells in Hongkong and Australia, are underground spaces for transferring and controlling urban underground pipelines, and the ground access ports are named sand well ports or inspection wells, which refer to well-shaped structures at confluence points between drainage pipelines and are convenient to inspect and dredge. The inspection shaft is usually covered by an inspection shaft cover.
In cities, all public water supplies, sewer pipes, telephone lines and optical fiber networks may be connected through underground passages under inspection wells. The inspection well is an outlet of the inspection well to the ground and is covered by an inspection well cover. The underground pipeline is mostly linear, when the underground pipeline needs to turn, an inspection well is arranged at a turning position, and the purpose is to ensure that the linear pipeline is not easy to block and a pipeline is easy to install. In addition, in order to facilitate the work and the safety, a manhole is installed in the middle of a pipeline with a certain length so as to facilitate the entrance and exit of the pipeline.
In the pollution discharge project, inspection wells with different designs can have different functions, such as a falling inspection well, a sand-separating inspection well and the like. The falling inspection well consumes kinetic energy by impacting the bottom of the inspection well from a high place to a low place when water enters the inspection well, can reduce the kinetic energy of water outlet, and is suitable for draining water from the high place to the low place. The sand-separating inspection well is characterized in that the bottom of the inspection well sinks down to collect garbage.
Because the channel below the inspection well cover is a sealed place, the concentration of gases such as methane, carbon dioxide and the like is often too high. Personnel such as cleaning workers, ditch repairing workers, telephone line technicians, firefighters for rescue and the like need to use a ventilator to introduce fresh air on the ground before entering work so as to avoid oxygen deficiency or air explosion and occupational disasters.
The inspection well has a main function of inspecting and dredging an entrance and an exit of a sewer, and has a function of draining water, and drainage systems can be largely classified into two types of confluence systems and split systems, and fine classification can be further classified into various types, such as a straight-line confluence system, a cutoff confluence system, a total treatment confluence system, and an incomplete split system.
So when taking place sewer jam, the drainage is unobstructed, and underground line is impaired, when the condition such as need overhaul, then will have the staff to open the inspection shaft lid, and the staff goes down along the cat ladder afterwards, carries out the operation in getting into the sewer. When workers carry out inspection well low operation, certain dangerousness exists, except that the concentration of underground methane, carbon dioxide and other gases is too high, and the like, when the workers carry out operation, because the inspection well cover is in an opened state, a pit hole exists on the ground, objects falling from the ground can fall from the inspection well opening, and the workers below are injured or injured by smashing, and the like. In view of the current situation, a protective device which is convenient to operate and high in reliability is sought, is used for providing protection for manual operation of an inspection well, and is a technical problem which needs to be solved urgently.
