中小型塔架采用构件地面现场组装整体架设旋转就位的施工方法,适用于边远山区和无大型起重设备的地区。这种施工方法所采用的主要机具——自立式中小型塔架(高100m 内)具有较好的稳定性、刚度和强度,施工架设时可充分利用其力学特性。一、施工过程1.确定塔架地面组装方案根据施工现场就位地形,使塔架的纵向中心轴线 Z 与水平面的夹角α_施≥0°(图1,图中 OAB 是塔架全高度范围)。
The small and medium tower uses the construction method of the ground assembly on the ground of the component to erect and rotate in place. It is suitable for the remote mountain areas and areas without large lifting equipment. The main machine used in this construction method, the self-supporting small and medium-sized tower (within 100m in height), has good stability, rigidity and strength, and can fully utilize its mechanical properties when it is erected and erected. First, the construction process 1. Determine the tower ground assembly plan According to the construction site in place terrain, so that the longitudinal center axis of the tower Z and the horizontal plane included angle α_ ≥ ≥ 0 ° (Figure 1, OAB in the figure is the tower full height range).
