在盐城发电厂六期扩建工程大型码头吊机的安装施工中。我们选用了钢丝网模套取代传统的木板模套作为设备基础的螺栓孔套。实践证明,应用于设备基础超深地脚螺栓孔是完全可行的。 1 施工程序 1.1 选用网眼5×5mm的钢丝网,根据地脚螺栓孔的设计要求,卷成单层目带底的圆柱体,搭接长度一般控制在5cm左右,再用18～20~#铅丝绑扎牢固。 1.2 为了增强钢丝网模套的强度和刚度,在钢丝网外周每隔20～30cm增加一道加强圈(即箍筋),并与钢丝绑扎成整体,这样可抵抗四周变形。
In Yancheng Power Plant Phase 6 Expansion Project Large Dock Crane Installation and Construction. We chose the wire mesh die set instead of the traditional wood die set as the bolt hole cover for the equipment foundation. Practice has proved that it is entirely feasible to apply ultra-deep foundation bolt holes to equipment foundations. 1 Construction Procedure 1.1 Mesh 5×5mm wire mesh is selected. According to the design requirements of the anchor bolt hole, the cylinder is rolled into a single layer with a bottom. The lap length is generally controlled at about 5cm, and then 18~20~# lead wire binding. firm. 1.2 In order to enhance the strength and rigidity of the steel wire mesh mold sleeve, a reinforcement ring (i.e., stirrup) is added every 20 to 30 cm around the steel wire mesh, and is integrally tied with the steel wire so that it can resist deformation around it.
