Problems solved by technology

[0002] With the continuous advancement of urbanization, the number of underground pipelines and lines is increasing. Inspection wells will be installed on important nodes of each underground pipeline or line. Each inspection well will have a matching manhole cover. Poor, often crushed, and because of the ventilation hole, the rainwater will flow into the inspection shaft from the ventilation hole when it rains, causing damage to the equipment and lines under the inspection shaft

Abstract

The invention relates to a manhole cover with pressure-resistant and waterproof functions, which comprises a manhole cover and a base. The manhole cover with pressure-resistant and waterproof functions is ingeniously designed, and is highly feasible. When a heavy object applies pressure on a stressed plate of the manhole cover, second supporting rods can extend out of the manhole cover, and are inserted into sockets of the base to play the role of decreasing pressure; in a rainy day, accumulated rainwater can flow into the base via drain grooves of the manhole cover, and can then flow into the ground via drain holes of the base, and thereby the water is prevented from flowing into an inspection well. Moreover, the manhole cover is provided with ventilation grooves, so that the air under the manhole cover can keep flowing. Furthermore, because the upper outlets of the ventilation grooves are higher than the water outlets of the drain grooves, the manhole cover can enable the air under the manhole cover to flow while proofing water.

Description

technical field [0001] The invention relates to a well cover with pressure-resistant and waterproof functions. Background technique [0002] With the continuous advancement of urbanization, the number of underground pipelines and lines is increasing. Inspection wells will be installed on important nodes of each underground pipeline or line. Each inspection well will have a matching manhole cover. Poor, often crushed, and because there is a ventilation hole, rainwater will flow into the inspection shaft from the ventilation hole when it rains, causing damage to the equipment and lines under the inspection shaft. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a manhole cover with pressure-resistant and waterproof functions in order to solve the deficiencies of the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is: a manhole cover with pressure-resistant ...
