A multi-purpose, safe, anti-theft and drainage urban pavement manhole cover

Abstract

The invention provides a multipurpose urban road surface well lid for safe burglary prevention and drainage of stagnant water and belongs to the technical field of municipal engineering. The multipurpose urban road surface well lid is characterized in that a protective sleeve is arranged on a well lid base; the inner wall of the protective sleeve is provided with two layers of steps; a wedged type protection net is placed on the step of the lower layer; a porous overturning cover is arranged on the step of the upper layer; a porous rotary cover is arranged on the surface of the overturning cover. The step inside the protective sleeve of the base is provided with the protection net for preventing people and objects from falling down; the upper end of the protection net is provided with a vibration-absorption type porous interlayer well lid which can overturn and rotate for a certain angle to be opened or closed by utilizing a movable supporting point; a special handle is used for rotating to close an upper cover of the interlayer well lid to realize the safe burglary prevention; the upper cover of the interlayer well lid is unscrewed to discharge road surface deposited water or flood to decompress, and a secondary burglary prevention lock for opening the well lid by using a key is mounted on the inner side wall of a water through hole in one end of an overturning well lid corresponding to an overturning well lid support. The multipurpose urban road surface well lid disclosed by the invention has the characteristics of low production cost, convenience in operation, dual safe burglary prevention and remission of urban road surface flood, and is the urban road surface well lid with the strong practicability.

Description

technical field [0001] The invention relates to a multi-functional, safe, anti-theft and drainage urban pavement manhole cover, which belongs to the technical field of municipal engineering. Background technique [0002] Urban pavement manhole covers relate to underground water supply and drainage pipelines, postal, electricity, gas pipelines and other industries, and have a long history of development. Traditional urban pavement well covers usually only place a simple movable cover in the fixed sheath on the well head, or open the cover with a common hinge at one end of the well cover, or use a simple hinge under the well cover for safety. The mesh rope is fixed. Due to the defects of traditional manhole covers, many pedestrian casualties and vehicle accidents caused by manhole cover safety problems in our country every year, as well as countless manhole covers being stolen or disasters caused by the accumulation of water in many cities or the surge of groundwater washing ...

AI Technical Summary

Problems solved by technology

[0003] 1. The movable manhole cover placed in the traditional manhole cover is often crushed by heavy-duty vehicles, or stolen by people, or washed away by floods, resulting in the vacancy of the wellhead, causing vehicles and pedestrians to be unable to pass through, causing traffic jams, and more seriously causing pedestrians crash;

[0004] 2. Although the traditional manhole cover has been improved to fix the anti-theft by hinges at one end of the manhole cover, or install nylon ropes at one end of the manhole cover as a protective net, the deformation of the manhole cover due to the long-term extrusion of heavy-duty vehicles will cause the water level in the underground water pipe to rise. If the pressure is too high, the manhole cover will be washed away. Long-term use of the nylon rope net will be useless after years of decay. The manhole cover and the rotted protective net will also cause vehicles and pedestrians to be impassable and pedestrians to fall to death;

[0005] 3. In the traditional manhole cover, there is also a method of inserting a key to install a safety lock through a small hole that can only accommodate the key in and out on the single-layer manhole cover. However, due to the deformation of the manhole cover after being squeezed by heavy-duty vehicles driving on the road, the manhole cover cannot be installed after being dislocated. It cannot be opened after being locked or locked, which will affect the maintenance of the sewer pipe. If the manhole cover is forcibly opened, the manhole cover will be scrapped or the manhole cover lock function will fail, and it will seriously affect the work efficiency;

[0006] 4. After the traditional manhole cover is closed, the road surface water caused by the heavy rain cannot be eliminated, which will cause urban road flooding and affect the traffic of vehicles and pedestrians;

[0007] 5. After the traditional manhole cover is closed, if the water level in the underground pipeline rises to form an outward extrusion force in case of heavy rain, if the manhole cover is not opened to discharge the flood, the manhole cover will be washed away or washed away; if the manhole cover is opened, it will cause Vehicles and pedestrians cannot pass, and even cause pedestrian safety accidents
