一、概述无井架液压滑升模板施工混凝土烟囱,是近几年兄弟单位在烟囱施工技术上的重大革新。其特点是:取消了以往为垂直运输及操作平台提升而在筒身内搭设的工具式钢井架,操作平台上的全部荷重由埋置在筒壁内的千斤顶杆承担,通过液压千斤顶及液压传动装置,边浇灌混凝土边提升。垂直 I. Overview The construction of a concrete chimney without a hydraulic derrick sliding template is a major innovation in the construction technology of the siblings in the chimney in recent years. Its characteristic is that the tool steel derrick that was built in the barrel body for the vertical transportation and the lifting of the operation platform has been eliminated. The whole load on the operation platform is borne by the jack rod embedded in the wall of the cylinder, through the hydraulic jack and the hydraulic transmission device. , while the concrete is being raised while pouring. vertical
