Noise-free, anti-settling and easy-to-open manhole cover

Abstract

The invention relates to the technical field of engineering pipelines, in particular to an easily-locked easily-opened noise-free anti-theft return-surging-prevention subsidence-prevention novel manhole cover. The easily-locked easily-opened noise-free anti-theft return-surging-prevention subsidence-prevention novel manhole cover is composed of a base, a manhole cover body, a manhole cover elliptic cylinder, a tip cone, a pressure-resisting rubber ring, an opening jacking left-handed screw and the like; the base and a roadbase are built into a whole in a multi-layer manner, various kinds of car pressing pressure are evenly transmitted to the roadbed for achieving subsidence prevention, the tip cone is arranged in the manhole cover elliptic cylinder, the pressure-resisting rubber ring is bonded on the manhole cover body to be assembled with the base and then achieves buffer, pressure reduction and noise prevention, the opening jacking left-handed screw is screwed in from a left-handed screw thread hole, a rotating handle is grabbed, the manhole cover elliptic cylinder is put into a base elliptic box body, a torsional spring is used for enabling the tip head of the tip cone and the annular rough inner wall of the base elliptic box body to be subject to jacking, locking and anti-theft operation, and the manhole cover body is mounted in place; during opening, the opening jacking left-handed screw is screwed into the left-handed screw thread hole, the spherical jacking face of the screw rod enables the tip head of the tip cone and the base elliptic box body to be unlocked, themanhole cover body is easily jacked and opened, the rotating handle is grabbed, the manhole cover body is moved, and multiple functions of easy locking, easy opening, noise prevention, theft prevention, return surging prevention, subsidence prevention and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering pipelines. The noise-free, anti-subsidence and easy-to-open inspection well cover is applied to inspection wells of various sizes and shapes in urban construction engineering pipelines. Background technique [0002] The inspection well is the entrance and exit of various underground facilities. The inspection well cover is the gatekeeper of the inspection well. It is an indispensable facility in the urban construction engineering pipeline. With the rapid development of urban modernization, the number of various inspection wells is also increasing sharply. To ensure the smooth flow of roads and the safety of traffic and pedestrians, it is also necessary to reflect the image of the city to a certain extent; it is also necessary to prevent noise from disturbing the people, prevent subsidence and avoid digging roads. People complain too much, and some use old bicycle tires or Other ru...

[0002] The inspection well is the entrance and exit of various underground facilities. The inspection well cover is the gatekeeper of the inspection well. It is an indispensable facility in the urban construction engineering pipeline. With the rapid development of urban modernization, the number of various inspection wells is also increasing sharply. To ensure the smooth flow of roads and the safety of traffic and pedestrians, it is also necessary to reflect the image of the city to a certain extent; it is also necessary to prevent noise from disturbing the people, prevent subsidence and avoid digging roads. People complain too much, and some use old bicycle tires or Other rubbers are used as gaskets to prevent noise, but within a few days these waste bicycle tires or rubber sheets are crushed into pieces by vehicles and scattered on the road, affecting the appearance of the city, and the noise still disturbs the people

At present, there are anti-theft manhole covers in various ways such as iron chains, hinge connections, counter-rotation, bolt plugging holes, lock keys, etc. in the anti-theft technology on the market, but their anti-theft performance is still very low, and thieves can easily destroy the connectors. The inspection manhole cover is frequently stolen; in case of heavy rain, the phenomenon of urban drainage inspection well backflow frequently occurs, and the inspection manhole cover is easily washed away and displaced, and is submerged by floods. The inspection well has become a trap and is difficult to be found, resulting in casualties. Some of them are equipped with anti-drop nets, but they still leave serious safety hazards for vehicles and pedestrians; some manhole covers pay attention to anti-theft but ignore the convenience of opening, anti-noise, anti-settling, anti-backflow and anti-rust. In the end, it was also difficult for me to open it myself, and I was unable to enter the inspection well to carry out related work such as pipe wiring, cleaning and maintenance.
