The Technology of Suspending Style Whole-Reinforcement of a Manhole Cover

During the process of traditional construction, quality problems often occur, such as loosening of manhole surroundings, cracks, sinking, losses of covers, vibration and abnormal sounds when driving, inaccurate control of the elevation of the manhole cover, inability to ensure the smoothness of the joining with the road surface, etc.. The technology of suspending style whole-reinforcement of the manhole cover can effectively resolve the above problems. This technology adopts fixed supports to suspend the manhole frame and adjust its elevation; set steel reinforced concrete perimeter beam beneath the frame to prevent the sinking of the cover; pre-buried steel bars are utilized to fix the cover, resist the horizontal push and prevent slides; pour the frame and steel reinforced concrete perimeter beam into an integral body to enhance the integrity of the structure. Make sure that no sinking occurs around the manhole and the cover is not easily lost and damaged and reduce the cost of replacing the cover. This technology bears great value of wide application.
