[0056] II. Specific usage method

[0057] Before on-site assembly, check and accept each component to ensure that the welding quality meets the requirements and each component has no defects. After the acceptance is completed, start the installation of this device. According to the width of this device, use a drill to drill eight expansion bolt holes with a depth of not less than 10 cm on the box girder wing plate 11. Use the expansion bolt 1.4 to fix the anchoring channel steel 1.1 of the lower vertical rod 1 on the bridge deck, and tighten the nut of the expansion bolt 1.4 with a wrench. Then use bolts to fix the upper vertical rod 2 and the lower vertical rod 1, use bolts to fix the upper crossbar 3 to the top of the upper vertical rod 2, and finally use bolts to connect the lower crossbar 5 with the lower vertical rod 1 to complete the installation of this device.

[0058] When installing the pump pipe 7, use the remote control to operate the electric hoist 4 to lower the chain. Then, use the steel wire rope 8 to loop around the pump pipe 7, and connect the other end of the steel wire rope 8 to the hook of the electric hoist 4. Use the remote control to retract the chain 4.10, driving the pump pipe 7 to rise to the designated position. Use the remote control to move the driving wheel 4.4 left and right to adjust the direction of the pump pipe 7 to facilitate the precise docking of the two pump pipes 7. After installation, adjust the fixed position of the lower crossbar 5 according to the required height of the pump pipe 7. Lower the chain 4.10 to place the pump pipe 7 inside the lower half hoop 6.9 of the fixing device 6. Loosen the chain 4.10, remove the hook and the steel wire rope 8, retract the chain 4.10, and use bolts to fasten the upper half hoop 6.10 and the lower half hoop 6.9 to complete the fixation of the pump pipe 7. When the pipe is blocked, the pump pipe 7 can also be quickly removed to avoid wasting resources caused by the hardening of concrete due to excessive time delay.

[0059] III. Quality Requirements

[0060] During the welding process, ensure that all members are horizontal and vertical, and full welding is performed at the welding parts. After welding, knock off the welding slag and conduct weld quality inspection to ensure that the weld length, depth, width, and reinforcement height meet the requirements. Do not hammer or press heavily during the transportation and storage of each component to prevent deformation of the connection parts of each component, which may cause difficulties in later installation. After the above steps are completed, spray anti-rust materials on this device to improve its durability, and regularly maintain the electric hoist 4 and the fixing device 6.
