Deep foundation pit concrete supporting beam cutting and dismantling construction method
The invention discloses a deep foundation pit concrete supporting beam cutting and dismantling construction method. Comprising the following steps of: 1, partitioning a support beam and drawing a cutting line; 2, removing concrete of the supporting beam by using an air pick to expose upper reinforcing steel bars; 3, a cutting machine operation platform is erected; 4, the cutting machine is installed in place; 5, the truck-mounted crane and the transport vehicle are in place, specifically, the truck-mounted crane slowly lifts the segmentation block and rotates and lifts the segmentation block into the flat car; and 5.4, then the flat car transports the cut concrete blocks to a designated site outside the site for breaking treatment. According to the cutting and dismantling construction method for the concrete supporting beam of the deep foundation pit, the situation that flying dust caused by supporting beam blasting or pickaxe machine construction pollutes air is avoided, the method is not affected by the construction environment, the method can be applied to urban areas and suburbs, construction is convenient, the construction progress is facilitated, and reserved steel bars below the supporting beam are effectively protected against damage.
本发明是一种深基坑混凝土支撑梁切割拆除施工方法；包括步骤1、支撑梁分块划分并画出切割线；步骤2、用风镐将支撑梁混凝土剔除露出上部钢筋；步骤3、搭设切割机作业平台；步骤4、切割机安装就位；步骤5、汽车吊及运输车就位：汽车吊缓慢将分割快吊起，转吊在平板车内；步骤5.4、然后平板车将切割砼块运至场外指定地点进行破除处理。本发明一种深基坑混凝土支撑梁切割拆除施工方法，此方法避免了支撑梁爆破或镐头机施工造成扬尘对空气的污染，不受施工环境影响，市区、郊区均可以应用，施工便利、施工进度有利，而且对支撑梁下方的预留钢筋有效保护不受破坏。
