Embodiment Construction
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0014] Such as figure 1 As shown, the main components of the embodiment of the present invention include a well base 5, a well shaft 9, and a well cover 1, wherein the upper opening 51 of the well base 55 is a ring-shaped structure (or called a short cylinder structure), and the lower part of the well shaft 9 The end surface is connected with the upper opening 51 of the well base 5 , and the lower surface of the well cover 1 covers the upper end surface of the well shaft 9 .
[0015] In order to adapt to the different buried depths of the well base 5, the well shaft 9 of the present embodiment includes a plurality of sub-well shafts. For example, the well shaft 9 of the present embodiment includes three sub-well shafts 2, sub-well shafts 3, and sub-well shafts 4 of the same specification and structure. The two ends of the sub-well sh...

An inspection well comprises a well seat, a well shaft and a well cover. The well shaft comprises multiple sub well shafts, two ends of the sub well shafts are sequentially connected end to end, blocky first protrusions are arranged on the lower end face of each sub well shaft positioned above, first grooves are formed in the upper end face of each sub well shaft positioned below, the first protrusions of the sub well shafts which are adjacent and positioned above are embedded in the first grooves of the sub well shafts positioned below, a second groove is formed in the upper surface of an opening above the well seat, first through holes which vertically extend are formed in the side wall of each sub well shaft, the first through holes of each sub well shaft are up-down correspondingly through, second through holes which vertically extend are formed in the side wall of an opening above the well seat, and the first through holes and the second through hole are up-down correspondingly through, a ventilation nozzle is arranged on the lower surface of the well cover and is of a pipeline structure, the other end of the ventilation nozzle horizontally extends on the lower surface of the well cover, and second protrusions are arranged on the lower surface of the well cover. Gathering of flammable and toxic gas in the well seat can be avoided.
Description
technical field [0001] The invention relates to an inspection well. Background technique [0002] In the fields of communication cables, power cables, water supply and drainage, and other infrastructure constructions, inspection wells are indispensable equipment, which is very important for the maintenance of pipelines and the medium in them. As we all know, due to the long-term closed environment, the gas in the pipeline cannot communicate with the outside world. If humus emits methane or other sources leak flammable or toxic gases, it will cause serious consequences when workers enter the pipeline for maintenance. The media has often reported in recent years. Workers suffocate when they enter the ground, manhole covers suddenly fly out, fire falls into manholes and causes explosions, etc., all of which are caused by the accumulation of flammable or toxic gases in the pipeline. Contents of the invention [0003] The object of the present invention is to provide an inspec...
