[0004] The technical solution adopted by this utility model is as follows: The pre-compression mechanism for the hanging basket of this utility model includes a truss located above the casting body, a bottom basket located below the truss and connected to the upper front crossbeam of the hanging basket through at least two first hangers, and a sliding beam located between the truss and the bottom basket. One end of the sliding beam is connected to the casting body, and the other end is connected to the upper front crossbeam through a second hanger. The feature is that a horizontal bar is fixedly connected to the casting body, and the upper end of an inclined bar is connected to the lower end of the horizontal bar, with the upper end of the inclined bar connected to the casting body. A first pull rod extending downwards is connected to the sliding beam, and the first pull rod is connected to the horizontal bar through a first driving device. The first hanger extends downwards and is connected to the bottom basket through a second driving device. During the pre-compression test, the first driving device applies a downward force to the sliding beam, and the second driving device applies a downward force to the bottom basket.
[0005] The first driving device of this utility model is any one or a combination of a cylinder, a hydraulic cylinder, a jack, and a motor.
[0006] The second driving device of this utility model is any one or a combination of a cylinder, a hydraulic cylinder, a jack, and a motor.
[0007] The present invention comprises two sliding beams, each of which is connected to two first tie rods. The lower ends of the two first tie rods are connected to a first bottom beam, and a first driving device is located between the first bottom beam and the crossbar.
[0008] The second driving device of this utility model is located between the bottom basket and the crossbar.
[0009] The second drive device of this utility model is provided with a pad beam acting on the bottom basket or crossbar below and / or above it.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] Compared with existing technologies such as surcharge preloading blocks, water tank preloading, and sandbag surcharge, which suffer from long construction times and low efficiency, this utility model uses a cast-in-place structure to fix a horizontal bar, a sliding beam to connect a first tie rod, and a first drive device to connect the first tie rod and the horizontal bar. The front upper horizontal beam is connected to the bottom basket via a first hanger, and the first hanger and the bottom basket are connected via a second drive device. When the first and second drive devices are running, they apply downward forces to the sliding beam and the bottom basket respectively, thereby simulating the usage environment to achieve preloading of the sliding beam and the bottom basket, saving manpower and material resources and improving construction efficiency.
