Embodiment Construction

[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] like figure 1 As shown, this embodiment provides a convex manhole cover for the escape opening of a comprehensive utility gallery, including a base 1 and a cover plate 2 hinged on the base 1 and capable of opening and closing. The cover plate 2 is a pyramid-shaped shell structure with multiple sides. This structure has the characteristics of high middle and low edge, and each side is a slope surface inclined from the center to the periphery. The cover plate 2 of this structure is not easy to The accumulation of sundries is formed, so as to solve the hidden danger that it is difficult to open from the inside of the comprehensive pipe gallery due to the accumulation of sundries on the cover plate 2, and prevent people from escaping safely.

[0026] The thickness of the cover plate 2 can be equal from the center of the cover plate 2 to...

Abstract

The invention relates to a convex manhole cover for an escape opening of a comprehensive pipe gallery, and belongs to the technical field of the comprehensive pipe gallery. The convex manhole cover includes a base and a cover plate hinged to the base and capable of being opened and closed. The cover plate is of a pyramid-shaped housing structure with multiple sides. The cover plate of the pyramid-shaped structure has the characteristics of the high middle and the low edge, debris is not prone to being accumulated on the cover plate, and the hidden danger that the cover plate is difficult to open from the inside of the comprehensive pipe gallery and an escape passage is blocked due to stacked items on the cover plate is eliminated.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery and relates to a convex well cover for the escape port of comprehensive pipe gallery. Background technique [0002] As a way of laying municipal pipelines, the comprehensive pipe gallery integrates various municipal pipelines by building a linear space tunnel structure underground, and leaves an operating space for maintenance and a passage for people to walk. The pipelines in the comprehensive utility corridor are arranged in a centralized manner, and the laying and maintenance of various pipelines are carried out directly in the comprehensive utility corridor, avoiding the repeated excavation of the road due to the laying and maintenance of underground pipelines, causing interference to traffic and residents’ travel. [0003] In order to ensure the safety of the workers in the underground comprehensive pipe gallery, the comprehensive pipe gallery should be equipped with person...
