The utility model relates to a post-expansion hanger system for removing the arch roof, which comprises the original arch culvert bottom plate, the arch roof to be demolished, the vertical suspender, the buffer sand layer and the jacking beam. The buffer sand layer is arranged on the original arch culvert bottom plate, the arch roof to be demolished is arranged above the original arch culvert bottom plate, the arch roof opening is arranged on the arch roof, the vertical suspender is arranged inside the arch roof opening, and the bottom of the vertical suspender is fixed. The top of the vertical suspender is provided with a horizontal sleeve at the top of the rod, and the horizontal suspender is arranged on the jack-up beam; the end of the vertical suspender is provided with a bottom of the rod, and the bottom of the rod bottom is formed by a hinged back expansion support plate, and the end of the hinged back expansion support plate is provided with an arc transition end. The beneficial effect of the utility model is that the cushioning sand layer is arranged on the bottom plate of the original arch culvert, so as to prevent the original arch culvert bottom plate from being damaged by falling accident during the lifting process of the arch culvert, and the vertical suspender with a stereotyped bottom is adopted when the arch culvert is lifted, thereby improving the construction efficiency of the arch roof demolition.

拱顶拆除后展吊架体系
本技术涉及一种拱顶拆除结构,特别涉及一种拱顶拆除后展吊架体系。
技术介绍
管道修复更新是指通过各种技术手段的处理,在不改变管道使用性质的前提下使管道恢复原来的功能。老城区排水管均采用雨污合流管,改造时须进行雨污分流,一般做法是作废合流管,新建雨水管和污水管。实际工作中,雨污合流管是否可以利用,如何将修复更新技术用活,降低成本值得探索,于此有关的配套技术也是施工技术创新的重要部分,若施工中需要对原拱涵进行拆除,并在原拱涵底板上部新建管涵,则重要的一步就是如何将原拱涵拱顶简单快速的拆除。鉴于此,为了提高原拱涵拱顶拆除的施工质量,亟待专利技术一种简单有效的拱顶拆除后展吊架体系,提高原拱涵拱顶拆除施工的施工质量施工效率。
技术实现思路
本技术的目的是克服现有技术中的不足,提供一种拱顶拆除后展吊架体系。这种拱顶拆除后展吊架体系,包括原拱涵底板、待拆拱顶、竖向吊杆、缓冲砂层和顶升梁,所述原拱涵底板上设置缓冲砂层,原拱涵底板上方设置待拆拱顶,待拆拱顶上设置拱顶开孔,拱顶开孔内设置竖向吊杆,竖向吊杆端部设置杆底定型化底端,所述竖向吊杆顶部设置杆顶水平套筒,所述水平套筒内设有水平吊杆,水平吊杆置于顶升梁上。作为优选:所述竖向吊杆端部设置杆底定型化底端,杆底定型化底端由铰接后展支板组成,铰接后展支板端部设置弧形过渡端。作为优选:所述水平吊杆置于顶升梁上,顶升梁两端底部设置顶升千斤顶及顶升卷扬。本技术的有益效果是:(1)本技术在原拱涵底板上设置缓冲砂层,防止在拱顶起吊过程中出现砸落意外而破坏原拱涵底板。(2)拱顶起吊时采用带有定型化底端的竖向吊杆,可提高拱顶拆除的 ...
