[0025] A bridge suspended casting hanging basket preloading system according to an embodiment of the utility model is described below with reference to the accompanying drawings.

[0026] See also Figures 1 to 3 According to an embodiment of the utility model, a preloading system for a suspended cast-in-place hanging basket for a bridge comprises at least two water bags 1 for arrangement on the bottom mold platform of the hanging basket, a plurality of water bags 2 for hanging on the front lower beam and the rear lower beam of the hanging basket, and an infusion subsystem for conveying water into each water bag 1 and each water bag 2. The number of the water bags 1 and the number of the water bags 2 can be determined according to the conditions of the bridge construction site, the specific structure of the hanging basket, the volume of the water bags 1, the volume of the water bags 2, etc. As an example, in this embodiment, the number of the water bags 1 is three, and the number of the water bags 2 is six. The three water bags 1 can be arranged side by side on the bottom mold platform of the hanging basket to be preloaded. Among the six water bags 2, three are hung on the front lower beam of the hanging basket at equal distances, and the remaining three are hung on the rear lower beam of the hanging basket at equal distances.

[0027] The infusion subsystem includes a first liquid channel 3 connecting a water source and a water inlet of a corresponding water bag 1, a second liquid channel 4 connecting a water source and a water inlet of a corresponding water bag 2, a first water pump 5 for promoting water from the water source to enter the corresponding water bag 1 through the first liquid channel 3, and a second water pump 6 for promoting water from the water source to enter the corresponding water bag 2 through the second liquid channel 4. In one embodiment, the number of the first liquid channels 3 may be three, the number of the first water pumps 5 may also be three, and each water bag 1 may be individually supplied with water by a first water pump 5 and a first liquid channel 3; the number of the second liquid channels 4 may be six, the number of the second water pumps 6 may also be six, and each water bag 2 may be individually supplied with water by a second water pump 6 and a second liquid channel 4. In another embodiment, each water bag 1 may share the same first water pump 5 and a part of the first liquid channel 3, and each water bag 2 may also share the same second water pump 6 and a part of the second liquid channel 4. Figure 1 Example: This embodiment does not limit the number of the first liquid channel 3 , the second liquid channel 4 , the first water pump 5 , and the second water pump 6 .

[0028] The first liquid channel 3 and the second liquid channel 4 can be installed with a check valve 7, a flow meter 8, etc. The flow meter 8 can obtain the capacity of the water in the corresponding water bag 1 and the water bag 2, and then determine the load applied by the water bag 1 and the water bag 2 to the hanging basket.

[0029] See now Figure 4 and Figure 5The water bag 1 includes a water bag body 10, and a webbing net 11 that is bonded to the outer surface of the water bag body 10 and the outer surface of the top. The water bag body 10 can be made of soft and durable materials such as PVC and rubber, and a space for accommodating fluids such as air and water is formed inside the water bag body 10. The webbing net 11 is composed of a longitudinal webbing and a transverse webbing, and each intersection of the longitudinal webbing and the transverse webbing is fixedly connected, which can be fixed by glue or fiber thread. The webbing net 11 can enhance the pressure resistance of the water bag body 10.

[0030] The water bag body 10 is generally rectangular in shape when filled with fluid. The water bag 1 also includes a plurality of straps 12 fixedly connected to the portions of the webbing net 11 that are adhered to the outer surfaces of the water bag body 10. The straps 12 can be used to fix the water bag 1 to the bottom mold platform. When the water bag 1 is placed on the bottom mold platform of the hanging basket, the water bag 1 can be filled with air, then moved to a set position, and then fixed with the straps 12, and then filled with water. This method can accurately position and fix the water bag 1 to avoid squeezing and shifting adjacent water bags 1. Using at least two water bags 1 can reduce the amount of water collected to one side when the bottom mold platform is tilted.

[0031] The top of the water bag body 10 is provided with an air hole, and the water bag 1 also includes an air channel 13 connected to the air hole, and the air channel 13 is provided with a regulating valve. When the water bag 1 is arranged on the bottom mold platform of the hanging basket, the water bag 1 needs to be filled with air, so in the process of filling the water bag 1 with water, the corresponding flow of air needs to be discharged. In this process, the regulating valve can be used to control the gas discharge speed so that the discharged air position can be quickly occupied by the input water to avoid the water bag 1 from sinking and shifting.

[0032] See now Figure 6 The water bag 2 includes a water bag body 20 and a sling set 21 surrounding the water bag body 20. The lower ends of the slings of the sling set 21 are fixed to the same circular bearing member 22, and the upper ends of the slings are connected to the buckle 23. The sling set 21 and the circular bearing member 22 jointly support the water bag body 20 after being filled with water.

[0033] The outer surface of the water bag body 20 surrounded by the annular bearing member 22 is attached with a reinforcing film 24, which can be a membrane structure made of the same material as the water bag body 20, or a membrane structure made of a material different from the water bag body 20, for example, a membrane structure made of soft and durable materials such as PVC and rubber. The reinforcing film 24 can reduce the risk of rupture of the part surrounded by the annular bearing member 22 due to lack of the carrying capacity of the sling.

[0034] The reinforcing membrane 24 and the outer surface of the water bag body 20 together form an arc-shaped arc space 25, in which a high-energy compound and an ignition device that creates conditions for the high-energy compound to release energy are arranged. During the pre-pressing process, if an abnormal condition is found in the hanging basket, the energy released by the high-energy compound can form a large opening in the part of the water bag body 20 surrounded by the annular bearing member 22, so as to quickly discharge the water contained in the water bag body 20, quickly unload it, and prevent major accidents. The high-energy compound can be trinitrotoluene, gunpowder, etc., and the ignition device can be a detonator. The bridge suspended casting hanging basket pre-pressing system also includes a control circuit (not shown in the figure) that is communicatively connected to the ignition device.

[0035] In this embodiment, the water bag 2 further includes a circular ring-shaped support member 26, which is arranged above the water bag body 20 and fixedly connected to each sling, and is used to open the four sides of the upper part of the water bag body 20 containing water. The circular ring-shaped support member 26 and the circular ring bearing member 22 can both be ring-shaped objects made of steel material.

[0036] Preferably, an exhaust channel 27 is formed at the top of the water bag body 20, and the water bag 1 and the water bag 2 are both provided with a drain port and a drain valve installed at the drain port.

[0037] The bridge hanging basket preloading system of this embodiment can easily control the load applied to the basket. During the preloading process, if the basket is found to be abnormal, it can be quickly unloaded to prevent major accidents. After the preloading is completed, the water bag 2, the water bag 1, etc. are more convenient to recycle and more economical than traditional concrete precast blocks.
