Prestressed concrete box girder transportation method
The invention provides a prestressed concrete box girder transportation method. The prestressed concrete box girder transportation method comprises the following steps that S1, a transportation platform is arranged below a prestressed concrete box girder to be transported to enter an arrangement space; s2, determining a support stress position and a key section position; s3, a plurality of SPMTs corresponding to the bearing capacity are arranged; s4, a plurality of distribution beams are erected on the SPMT; s5, the SPMT with the erected distributive girder is driven to the bottom of the prestressed concrete box girder; s6, a wedge-shaped sleeper is erected on the distribution beam; s7, the two ends of the wedge-shaped sleeper are beaten; s8, a strain gauge and an electric measurement displacement meter are attached to the prestressed concrete box girder; s9, SPMT jacks the prestressed concrete box girder through a lifting mechanism, so that the prestressed concrete box girder is separated from the original supporting position; and S10, the SPMT is controlled to move to the preassembling position. Transportation is stable, and damage such as cracking of the box girder is avoided.
本发明提供了一种预应力混凝土箱梁运输方法，包括以下步骤：步骤S1:在待运输预应力混凝土箱梁下方设置运输平台进入布置空间；步骤S2:确定支撑受力的位置及关键断面位置；步骤S3:设置对应承载力的多台SPMT；步骤S4:将多条分配梁架设在所述SPMT上；步骤S5:将架设好分配梁的SPMT开至所述预应力混凝土箱梁底部；步骤S6:在所述分配梁上搭设楔形枕木；步骤S7:敲打所述楔形枕木两端；步骤S8:所述预应力混凝土箱梁贴附应变片及电测位移计；步骤S9:SPMT通过升降机构顶升所述预应力混凝土箱梁，使其脱离原始支撑位；步骤S10:控制SPMT移动至预装位置。本发明运输平稳、避免箱梁出现开裂等损伤。
