High-altitude dismantling method for concrete chimney
The invention relates to the technical field of chimney dismantling construction, in particular to a concrete chimney high-altitude dismantling method which comprises the steps that a plurality of anchoring parts are fixed to a chimney according to preset positions; a plurality of slideways are arranged in the circumferential direction of the chimney, and a triangular support is installed on the uppermost slideway steel pipe; an operation platform is mounted on the triangular support; wall dismantling seams are chiseled in the operation platform in the circumferential direction of the chimney every 3-5 m, force towards the interior of the chimney is applied to concrete slabs between the wall dismantling seams, the connecting positions of the bottoms of the concrete slabs and the lower-layer chimney are removed, and the concrete slabs fall into the chimney; the operation platform is moved towards the next layer, dismantling operation is carried out, and the operation is repeated until dismantling operation is completely completed; the annular aerial work platform is innovatively introduced, workers carry out dismantling operation layer by layer from top to bottom on the platform and are not limited by adjacent buildings, and meanwhile flying stones and large-area flying dust are effectively avoided; and the structure integrity of the lower part of the chimney can be ensured, and accurate local dismantling is realized.
本发明涉及烟囱拆除施工技术领域，具体的说是一种混凝土烟囱高空拆除方法，包括，将若干锚固件按预设位置固定于烟囱上；滑道沿烟囱环向设置若干滑道，在最上层滑道钢管上安装三角支撑；在三角支撑上安装操作平台；在操作平台上沿烟囱环向每间隔3‑5m凿除一条拆墙缝，在拆墙缝之间的混凝土板上施加向烟囱内的力，剔除混凝土板底与下层烟囱连接位置，使混凝土板掉落至烟囱内部；向下一层移动操作平台，进行拆除作业，重复至拆除作业全部完成；本发明创新性地引入了环形高空作业平台，工人在此平台上自上而下逐层进行拆除作业，不受邻近建筑物制约，同时有效避免了飞石与大面积扬尘的产生；还能确保烟囱下部的结构完整，实现精准的局部拆除。
