The invention relates to a manhole cover for an escape exit of a comprehensive pipe gallery, and belongs to the technical field of the comprehensive pipe gallery. The manhole cover comprises a base and a cover plate, wherein the cover plate is hinged on the base and can be opened and closed. A plurality of stiffening ribs are arranged on the cover plate, the stiffening ribs are arranged on the external surface of the cover plate, and the heights of the stiffening ribs decrease gradually from the center of the cover plate to the edge of the cover plate. The stiffening ribs arranged d on the external surface of the cover plate play the roles of strengthening the strength of the cover plate and improving the load bearing capacity and anti-deformation capacity of the cover plate, and moreoverthe raised stiffening ribs form a discontinuous inclined slope surface with a high middle and a low edge on the external surface of the cover plate. Debris accumulation is not easy to form on the cover plate with the structure, the possibility that the cover plate is difficult to be opened from the inside of the escape exit to block an escape way due to the stacking of items on the cover plate iseliminated from the design, and the smooth internal opening of the cover plate and the unobstructed escape way are ensured.
本发明涉及一种综合管廊逃生口井盖，属于综合管廊技术领域。包括底座和铰接在底座上且可启闭的盖板，所述盖板上设有若干加筋肋，所述加筋肋设于盖板的外部表面上，各加筋肋的高度从盖板中心至盖板边缘逐渐降低。在盖板的外部表面上设置的加筋肋，不仅起到加强盖板强度、提高盖板承重和防变形能力的作用，而且凸起的加筋肋在盖板的外部表面形成一个不连续的中间高、边缘低的倾斜坡面，这一结构的盖板上不易形成杂物堆积，从设计上消除因盖板上堆放物品导致难以从逃生口内部打开，堵塞逃生通道的可能性，保障盖板内部开启顺利及逃生通道畅通。
