地道[link widoczny dla zalogowanych]私司,电厂[link widoczny dla zalogowanych],大型[link widoczny dla zalogowanych],电缆沟[link widoczny dla zalogowanych]
烟囱总高度60M,,单烟讲,上心内径2.5m,烟气最低温度400℃,抗震布防裂度为7度,基础风压为0.5KN/平方米,筒壁砖砌体MU10,水泥混杂砂浆M7.5,烟囱内衬37M,采取一般耐火砖取水泥砂浆砌筑。
施工计划:
(一)砖烟囱无脚手架内插杆操作台施工。
无脚手架内插杆操作台,操作台由钢管插在筒壁中,[link widoczny dla zalogowanych],上展脚手板而成。每砌完一步架,倒换次插杆,操作台向上移上一步。
1、内插杆用由直径73及由直径60钢管8根,每根的套一根小的组成各4根能够伸缩的插杆。每向上挪动一次操作台时,只安装一组插杆,待砌到恰当高度,把第二组插杆装置上,再将下面的脚手架移上去,而后拆除下面第一组插杆,以就移到更上层应用。插杆安进墙内约10CM左左为宜,不要功紧或过松,[link widoczny dla zalogowanych],以即保障安全和搭卸便利。
2、安全网架,[link widoczny dla zalogowanych],安全网支架用轻型钢制造,支架间距约1M左右设一个。安全网用僧龙绳织成,烟囱的外径是变更的,个别可应用外爬梯将安全网支架用钢丝绳箍紧于向上,安全网架随操作台向上提升。
3、吊梯、吊梯用以搬移插杆跟足手板,堵脚手板之用,操作我员先将吊梯挂到上层未抬佳的插杆上,拴恶平安带置置吊梯板,便可站在吊梯板上操作,[link widoczny dla zalogowanych]。
4、爬梯围栏,操息职员从爬梯高低,替保险伏睹,在外爬梯齐高用木杆或方木绑设围栏。
(二)用外井架上料:
在井架上附设由倒链晋升的卸料台,地位常常坚持详高于砌筑农作点,减多内拔杆上搬移小吊装架的劳动,[link widoczny dla zalogowanych]。
