Silica fume concrete prefabricated piping shaft
The invention relates to the field of piping shafts, in particular to a silica fume concrete prefabricated piping shaft which comprises a well body, a cover body, a protective net and an abutting ring bag, the well body is provided with an installation cavity for pipeline installation, the protective net is connected to the inner wall of the installation cavity, and the inner wall of the installation cavity is provided with a closing cavity for the cover body to rotate. The end face of the cover body abuts against the inner wall of the closed cavity and seals the mounting cavity, the abutting ring bag is connected to the inner wall of the closed cavity, and the inner ring of the abutting ring bag can abut against the circumferential outer wall of the cover body to form sealing. The well body, the protective net and the abutting ring bag are arranged, and the well body is prepared from silica fume concrete, so that the compressive strength and durability of the well body are improved, in the long-term use process of the well body, external rainwater is not prone to permeating into the mounting cavity, the protective net is not prone to being corroded by the rainwater, the pressure bearing capacity of the protective net to pedestrians is guaranteed, and the service life of the well body is prolonged. And the safety guarantee degree of the well body to pedestrians is improved, so that the use safety of the silica fume concrete prefabricated pipeline well is improved.
本申请涉及管道井的领域，尤其是一种硅灰混凝土预制管道井，包括井体、盖体、防护网和抵紧环囊，井体具有供管道安装的安装腔，防护网连接在安装腔内壁上，安装腔内壁开设有供盖体转动的闭合腔，当盖体朝靠近安装腔的方向转动时，盖体端面抵紧闭合腔内壁并封闭安装腔，抵紧环囊连接在闭合腔内壁，抵紧环囊内圈能够抵紧盖体周向外壁形成密封。本申请中井体、防护网和抵紧环囊的设置，井体是由硅灰混凝土制备而成，从而提高井体自身的抗压强度和耐久性，使井体长期使用过程中，外界雨水不易渗透进入安装腔内，防护网不易受雨水腐蚀，保证防护网对行人的承压能力，使井体对行人的安全保障程度提高，从而提升对硅灰混凝土预制管道井的使用安全性。
