A municipal manhole cover which is safe and anti-theft and has anti-odor function

Abstract

The invention discloses a municipal manhole cover which is safe and anti-theft and has the function of preventing peculiar smell. There is a rotating shaft in the middle of the well cover, and the well cover is placed in the cover seat. Several triangular iron blocks are fixed on the side and bottom of the cover seat, and the bottom surface of the cover seat between the triangular iron blocks is provided with circular screw holes. , the side of the cover base is provided with a rectangular hole, and the anti-theft device passes through the rectangular hole to fix the well cover, and the upper side of the cover base is fixedly equipped with a protective cover, and the protective cover is provided with two groups of left and right symmetrical inwardly protruding iron pieces , the protective cover is provided with a detachable steel wire protective net. The manhole cover of the present invention emphasizes safety, reliability and anti-theft, and at the same time ensures that the manhole cover and the road surface fit together, avoids noise interference, enhances drainage performance, and also isolates peculiar smells discharged underground.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to a municipal manhole cover which is safe and anti-theft and has the function of preventing peculiar smell. Background technique [0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers. They are generally round and can be used for green belts, sidewalks, motorways, Manhole covers such as piers and alleys are the closures on the top of the entrances and exits leading to underground facilities. Manhole covers are required to be installed in places where tap water, telecommunications, electricity, gas, heat, fire protection, sanitation and other public facilities are installed.

[0002] Manhole covers are used to cover roads or deep wells at home to prevent people or objects from falling. According to the material, they can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers. They are generally round and can be used for green belts, sidewalks, motorways, Manhole covers such as piers and alleys are the closures on the top of the entrances and exits leading to underground facilities. Manhole covers are required to be installed in places where tap water, telecommunications, electricity, gas, heat, fire protection, sanitation and other public facilities are installed. With the rapid development of my country's economy , my country's infrastructure construction has ushered in a new cycle. The market demand for manhole covers in urban planning and road construction is huge, but manhole covers are often crushed and damaged, resulting in a decline in the safety of roads and facilities. Talking about manhole cover standards, analyzing the rationality of standard setting

[0003] The existing manhole covers generally do not have anti-theft devices, so they are often lost, which not only causes economic losses, but also endangers the safety of pedestrians and vehicles. Since the surface of the manhole cover is required to be flat, it is not easy to lock it in an ordinary way. If the fit is not tight, the tires will collide with the manhole cover when the vehicle is overrun, and the manhole cover becomes one of the noise sources in the city. The manhole cover and the road surface can be tightly attached, which not only eliminates the noise, but some manhole covers have low drainage efficiency when they are not opened, and cannot be isolated The peculiar smell emitted from underground affects the appearance of the city
