In addition, for convenience and safety, inspection wells are provided in the middle of a certain length of pipeline to facilitate the entry and exit of the pipeline.
In the sewage disposal engineering, the inspection wells with different designs can have different functions, such as a falling grade inspection well, a sand isolation inspection well and the like. The falling inspection well is that the entering water is collided with the inspection well bottom from high place to consume kinetic energy, which can reduce the kinetic energy of the exiting water, and is suitable for draining water from high place to low place. The sand-isolating inspection well is characterized in that the bottom of the inspection well is sunk to collect garbage. Because the ditch below the inspection well cover is a sealed field, the concentration of methane, carbon dioxide and other gases is often too high. The fresh air on the ground is introduced by using a ventilator before entering the work so as to avoid oxygen deficiency or air explosion and occupational disasters
The underground operation of the inspection well requires that a safety fence is arranged on the periphery of the well to ensure the personal safety of the operation site, meanwhile, ventilation is required to be kept at all times, a wellhead is provided with a temporary barrier, a certain potential safety hazard still exists, meanwhile, a visual escape passage is reserved for the wellhead, the operation of operators is convenient, pedestrians are protected, the pedestrians are prevented from falling into the well to cause personal casualties, and therefore the temporary anti-falling protection device for the wellhead of the inspection well is required to be designed.
