在目前桥梁及其它高耸建(构)筑物的施工中,塔机布置是施工组织设计中的棘手问题。以斜拉索大桥为例,通常将塔机布置在大桥桥轴线方向的地面上,以获取最大工作覆盖面,但这样布置存在着塔身妨碍桥面施工的问题。因此在主塔建造到一定高度时,必须将塔机地面上的基础转移到不影响桥面施工
In the current construction of bridges and other towering structures, the tower crane layout is a thorny issue in the construction design. Taking a cable stayed bridge as an example, the tower crane is usually arranged on the ground in the axis direction of the bridge to obtain the maximum working coverage. However, there is a problem that the tower body hinders the construction of the bridge deck in this arrangement. Therefore, when the main tower is constructed to a certain height, the foundation on the tower crane must be transferred to the bridge deck without affecting the construction
