Insertion type road inspection well operation protection frame

Abstract

The invention discloses an insertion type road inspection well operation protection frame, and relates to an inspection well operation protection frame. The insertion type road inspection well operation protection frame is characterized in that an insertion ring rod (13) slightly smaller than a wellhead (36) of an inspection well is arranged in the middle of the lower end of a frame body, three ormore screw holes B (32) are evenly distributed in the four sides of the insertion ring rod, screw rods (33) of T-shaped screws (12) matched with the screw holes B in number penetrate through the inner sides of the screw holes B of the insertion ring rod, and the outer ends of the screw rods are meshed with the lower part of an inner protruding ring (34) of a wellhead well ring (35) to obtain theanti-displacement of the frame body; and a warning lamp (1), an illuminating lamp and an ventilation fan (4) are arranged on the upper end face of the frame body, and a telescopic pipe (7) capable ofbeing inserted into the inspection well is arranged on an air outlet of the ventilation fan. The warning lamp is used for warning passersby, the ventilation fan provides fresh air for the underground,and the insertion ring rod inserted into the wellhead of the inspection well locks the inner protruding ring of the wellhead well ring through the T-shaped screws to prevent the passersby from falling into the inspection well.

Description

【Technical field】 [0001] The invention relates to a protective frame for inspection well operation, in particular to a plug-in type protective frame for inspection well operation on roads. 【Background technique】 [0002] There are usually multiple inspection wells on the roads of the city, and the inspection wells supply cables, communication lines, street lamp wires, gas pipelines, water supply pipe networks or sewage, rainwater pipes, and supply enterprises, institutions, commercial supermarkets and rainwater pipes near the road through the installation of inspection wells. Residential area infrastructure, the line interface or pipeline valves set in the inspection well will be subject to long-term erosion by moisture or rainwater, and the aging of the lines and pipelines will occur, and the affiliated units will conduct inspections or emergency repairs through the inspection well; The entry of rainwater or sewage and the lack of air flow in the inspection shaft lead to th...

Problems solved by technology

[0002] There are usually multiple inspection wells on the roads of the city, and the inspection wells supply cables, communication lines, street lamp wires, gas pipelines, water supply pipe networks or sewage, rainwater pipes, and supply enterprises, institutions, commercial supermarkets and rainwater pipes near the road through the installation of inspection wells. Residential area infrastructure, the line interface or pipeline valves set in the inspection well will be subject to long-term erosion by moisture or rainwater, and the aging of the lines and pipelines will occur, and the affiliated units will conduct inspections or emergency repairs through the inspection well; The entry of rainwater or sewage and the lack of air flow in the inspection shaft lead to the high concentration of methane, carbon dioxide and other gases in the inspection shaft. Therefore, occupational disasters such as lack of oxygen for the workers in the inspection shaft often occur, and there are also deflagration caused by careless smoking or spot welding sparks. Occurrence; There are also accidents of pedestrians falling into the inspection shaft due to the unattended wellhead or the short-term departure of the personnel on duty during the construction of the inspection shaft. Therefore, some construction workers place reflective cones near the construction inspection shaft. The reflective cone is easy to be blown away by the wind, and there are also incidents where passers-by inadvertently knock down the reflective cone, which will cause passers-by to fall into the inspection well and injure the construction workers in the inspection well
