Construction method for improving in-position precision of swivel bridge
The invention relates to a construction method for improving the in-position precision of a swivel bridge, which is characterized in that a section of flexible body with adjustable length is arranged in the opposite direction of the rotation direction of a swivel main beam, and the flexible body has certain elastic deformation capability; when the rotation main beam rotates, a flexible body with a certain length is reserved, and the kinetic energy of the rotation main beam during rotation is removed through elastic deformation of the flexible body, and the rotation main beam is made to stop slowly; and when the rotating main beam is in place, acting force is applied to the rotating main beam through the flexible body, and the beam body posture of the rotating main beam is adjusted. The device has the advantages that the problems of consumption of applied redundant kinetic energy and no damage to the structure from rotation to static and accurate in-position of the structure when rotation is nearly finished are solved, the problem of accurate adjustment of bridge rotation in-position is solved, and the problem of easy out-of-plane rotation during fine adjustment of a bridge body is solved; the safety problem and the precision control problem of rotation in-position can be safely and effectively solved; the device is simple in structure, low in cost, controllable in swivel in-position precision, safe and controllable in swivel energy consumption and capable of being recycled.
本发明涉及一种提高转体桥就位精度的施工方法，在转体主梁的转动方向的反方向设置长度可调节的一段柔性体，柔性体具有一定的弹性变形能力；在转体主梁转动时，预留一定长度的柔性体，利用柔性体的弹性变形卸除转体主梁在转体时的动能并使其缓慢停止；在转体主梁就位时，利用柔性体向转体主梁施加作用力，调整转体主梁的梁体姿态。本发明的优点是：解决了转体临近结束时，结构从转动到静止及精确就位、施加的多余动能消耗且不损伤结构的问题，解决了桥梁转体就位精确调整的问题，解决了梁体精调时容易发生平面外转动的问题；可安全有效的解决转体就位的安全问题和精度控制问题；成本较低，转体就位精度可控，转体耗能安全可控，装置可循环使用。
