Problems solved by technology

The manhole cover of this technical solution has the following deficiencies in the use process: the cast iron manhole cover is prone to beating when vehicles pass by, and there is often a loud knocking sound between the cover plate and the well seat, which not only affects the nearby people Production and life, and make the driver have greater concerns and affect driving safety

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0010] Such as figure 1 The shown vibration reduction and sound-absorbing inspection well cover includes a well base 5 and a cover plate 1 mounted on the well base 5. An elastic pad 2 is housed in the cavity surrounded by the side wall of the cover plate 1 and the bottom plate 3. The side of the elastic pad 2 and the There is a gap of 20 mm between the inner surfaces of the cover plate 1, and the contact surface between the upper surface of the elastic pad 2 and the inner surface of the cover plate 1 is an arc surface, and the radius of the arc surface is between 1800 and 2000 mm; the cover plate 1 and the bottom plate 3 are glued The rear frame is installed on the well seat 5; when the vehicle passes by, the impact force of the vehicle on the inspection well cover makes the cover plate 1 and the elastic pad 2 elastically deformed, and this elastic deformation can eff...

Abstract

The invention discloses an inspection well cover having functions of vibration attenuation and sound attenuation and relates to the technical field of municipal facilities manufacturing. The inspection well cover comprises a well seat and a cover plate arranged on the well seat, and is characterized in that the cover plate is connected with a bottom plate and then erected on the well seat; an elastic cushion is arranged in a hollow cavity which is encircled by a side wall of the cover plate and the bottom plate; a contact surface of the upper surface of the elastic cushion and the inner surface of the cover plate is a cambered surface; a gap is reserved between the side of the elastic cushion and the inner side surface of the cover plate; and an elastic member is arranged between the side of the cover plate and the well seat. Compared with the prior art, the inspection well cover has the advantages that the elastic member is inlaid between the cover plate and the well seat, because of the impact force of a vehicle acted on the inspection well cover having functions of vibration attenuation and sound attenuation, when the vehicle goes by, the cover plate and the elastic cushion are elastically deformed; and moreover, by the elastic deformation, the impact force of the vehicle on the inspection well cover can be effectively absorbed to be functioned as vibration attenuation.

Description

technical field [0001] The invention relates to the technical field of municipal facilities manufacturing, in particular to a cover for closing ground entrances and exits of underground facilities. Background technique [0002] Ground entrances and exits of underground waterways and pipe network facilities are often inevitably set on ground roads. In order to ensure the normal passage of road pedestrians and vehicles, inspection well covers with a certain strength need to be covered at these exits. This is used to close underground facilities. The inspection well cover of the ground entrance and exit, the existing typical technical scheme is roughly: there is a well seat in the shape of a circle, which is used to connect with the ground buildings, and a roughly circular cover plate is installed on the well seat. When the cover plate is installed on the well base, the top surface of the cover plate is generally flush with the upper end surface of the well base. In order to fa...
