[0002] During the construction of a bridge, in order to ensure the safety and stability of the beam during the temporary storage stage in the beam storage area, it is usually necessary to use a strut. The design of the anti-overturning strut must not only ensure the safety and stability of the beam during the storage stage in the beam storage area, but also ensure that it is easy to disassemble during the process of lifting the beam. It is now common to use sleepers to support the cross beams at the opposite ends. In the existing sleeper support construction process, the following problems mainly exist: the support strength of the sleeper support is not enough, and when the double-layer beam is stored, it will cause the pressure of the bottom beam to increase, resulting in the fracturing of the sleepers and the overturning of the beam, causing construction safety accidents or quality accidents; and due to the different horizontal slopes of the bottom of the beam, the sleepers cannot effectively support the prefabricated T-beams of the second layer. If the support is improper, it may cause bias pressure on the first layer of stored beams, and cannot effectively support the prefabricated T-beams, causing the prefabricated beams to overturn.
