Integral squelch anti-stealing manhole cover

Abstract

The invention discloses various well covers on road surfaces. Integral silent anti-theft manhole cover, including reinforced concrete well shaft, embedded metal parts, well shaft chassis, well plate, well cover pressure ring, well cover, elastic collar and wedge ring, etc. The upper eaves of the reinforced concrete shaft are prefabricated and embedded with four metal parts with round holes. The reinforced concrete wellbore is fixed on the wellbore chassis, and the bolts pass through the wellpan, well cover pressure ring and the prefabricated metal parts of the wellbore upper eaves are fixed with nuts, so that the three are fixed as a whole. The cover ring is provided with a groove, and the well cover is placed on the well plate, and at the same time, it is fixed with an elastic collar embedded in the groove of the cover ring to achieve anti-theft effect. Insert a wedge ring between the well cover and the well plate. Since the contact surfaces of each component can be in good contact, vehicles passing by will not generate noise due to defects in the manhole cover itself. The present invention is characterized by reasonable design, relatively low construction cost, and simple construction operation, and is especially suitable for passages with high density of people and vehicles, high-end communities, and the like.

Description

technical field [0001] The invention belongs to various well shafts and well covers on the road surface. Background technique [0002] Pavement wells include sewage wells, tap water wells, and cable wells, which are essential facilities for municipal construction in every city. However, there are two major problems in the currently used pavement manhole covers: first, due to the lack of processing or construction quality, the gap between the edge of the manhole cover and the base; The bumps make a lot of noise; secondly, the problem of missing manhole covers has become a major public nuisance in society, and the consequences are miserable. Therefore, the development of manhole covers with quiet and anti-theft functions has become a product of interest to everyone. At present, there are many types of anti-theft manhole covers, some of which are silent, but the actual large-scale popularization and application are rare. Tracing it to its cause mainly has the following probl...

Problems solved by technology

However, there are two major problems in the currently used pavement manhole covers: first, due to the lack of processing or construction quality, the gap between the edge of the manhole cover and the base; The bumps make a lot of noise; secondly, the problem of missing manhole covers has become a major social hazard, and the consequences are miserable

The main reasons are as follows: high cost; complicated operation; limited service life and design defects, etc.
