Description

Anti-drop formula pavement stealthy well lid of pavement Technical Field The utility model belongs to the technical field of well covers, and particularly relates to an anti-falling pavement invisible well cover. Background With the rapid development of cities, the urban rate is greatly increased, and new projects start to show a descending trend. The quality improvement and efficiency enhancement of the old urban area and the urban area transformation project are more and more, and especially the road transformation is more and more. The urban road planning and municipal road network system development are not synchronous, natural abrasion and various loads which are accumulated in the daily life are added, pavement and auxiliary systems built in the early years are aged, particularly pavement invisible well covers of the pavement are related to fire protection, water supply, strong and weak electricity and the like, inspection or use is required to be frequently conducted, passing loads and water flow erosion are added, a plurality of invisible well covers are seriously loosened, misplaced, fallen and even broken, the urban image appearance is affected, great difficulty is caused to the passing and drainage of the existing pavement, and potential safety hazards are inevitably formed due to untimely repair or treatment, so that underground facility equipment is damaged. At present, various projects are improved for old urban areas and streets, pavement invisible pavement manhole covers are common pavement manhole covers in the market, and the technology of pavement manhole covers, cement slurry, mortar and pavement stone is adopted. The well lid and the cementing material can not be combined after finishing, the paving face bricks and the well frame can not be completely closely adhered to each other, so that water seepage pollution or erosion is caused in the later period, and particularly, for the well which is repeatedly required to be opened for inspection or use, the paving of the whole face bricks is loosened and peeled off under the action of external force, so that the service life of the well lid is greatly shortened, and meanwhile, the loosened face bricks can cause object striking and injury to operators. In order to ensure construction quality and prolong the service life of the paved well cover, an anti-drop pavement invisible paved well cover is provided. The existing paving well cover is cast iron filling well cover manufactured by manufacturers, the well cover is only used as a receiving container for paving materials, the bottom surface of the well cover is a ribbed cast iron plate surface, and one circle of well frame is a smooth cast iron plate surface. When in construction, mortar is virtually paved to the height of the well frame, facing stone is paved on the surface layer, the facing stone is knocked and compacted by a hammer and then is formed, the facing stone is stood for one to two days after finishing, maintenance and forming are carried out, and then traffic is opened. In the prior art, the bottom surface and the side surface of the well lid are in direct contact with paving mortar and cement paste materials, the combination effect of the smooth surface of the well lid and paving cementing materials is poor, and certain gaps can exist all the time. If only receive vertical pedestrian or other vertical effort, then this well lid facing material can keep the laminating of longer time, to fire control well, water supply well, the electric power well etc. that often need open, because need often open the inspection, external disturbance is great, and the monoblock is mated formation receives vertical ascending pulling force and the downward gravity component of slant for the condition of becoming flexible, peeling off appears mating formation. Meanwhile, the prior art is not closed to the contact surface of the well lid and the paving material, a tiny gap is reserved all the time, the combination of the well lid and the paving material is easily damaged due to later water erosion, the service life of the well lid is influenced, and meanwhile loose stone is easy to permeate water, pump slurry and even fall down, so that potential safety hazards are generated. Disclosure of utility model In order to solve the problems in the prior art, the utility model aims to provide an anti-falling pavement invisible manhole cover, which can prevent face bricks from loosening or peeling under the action of gravity when the manhole cover is lifted from one side. The technical scheme adopted by the utility model is as follows: The utility model provides an anti-drop formula pavement stealthy well lid, including the well frame, it has the face brick to mat formation in the well frame, the front side of well frame is provided with the operating hole that is used for mentioning the well frame, rear side drive mechanism is installed to the rear side of well frame, be provided with the dowel steel that ex
