Method for quickly positioning and hoisting prefabricated box girder adjacent to double-crane hoisting of high-speed rail
The invention relates to a quick positioning and hoisting method for a prefabricated box girder adjacent to double-crane hoisting of a high-speed rail, which comprises the following steps: respectively arranging traction equipment at four corners of the prefabricated box girder, respectively connecting each traction equipment with the corresponding corner position of the prefabricated box girder, respectively arranging hoisting equipment at two sides of the prefabricated box girder, and connecting the hoisting equipment with the prefabricated box girder, the traction equipment and the hoisting equipment can control the position state of the prefabricated box girder during hoisting; a limiting device is installed between every two adjacent support cushion stones, and the limiting devices are used for limiting the beam falling position of the prefabricated box beam; the prefabricated box girder is moved to the designed position through traction equipment and hoisting equipment, girder falling is conducted, and the prefabricated box girder falls onto the support padstone under the limiting effect of a limiting device; and the prefabricated box girder and the support padstone are temporarily fixed, and the traction equipment and the hoisting equipment are removed. The method has the advantages that the manual labor time is shortened, the danger coefficient is reduced, the positioning precision is improved, the construction efficiency can be improved, and the construction period is effectively shortened.
本发明涉及一种用于紧邻高铁双机抬吊的预制箱梁快速定位吊装方法，在预制箱梁的四角位置分别布置牵引设备，各牵引设备分别与预制箱梁对应的一角位置连接，同时在预制箱梁的两侧分别布置吊装设备，吊装设备连接预制箱梁，牵引设备和吊装设备均可控制预制箱梁在吊装时的位置状态；在相邻的支座垫石之间安装限位装置，限位装置用于对预制箱梁的落梁位置进行限位；利用牵引设备和吊装设备将预制箱梁移动其设计位置并进行落梁，预制箱梁在限位装置的限位作用下落梁在支座垫石上；将预制箱梁与支座垫石进行临时固定，移除牵引设备和吊装设备。本发明的优点是：减少人工劳动时间，降低危险系数，提高定位精度，且可以提高施工效率，有效缩短施工工期。
