AI Technical Summary
In the construction of high-speed railway bridges, the pre-embedded PVC water pipes in the pre-embedded holes of the tenon-shaped anti-fall beams suffer from problems such as insecure reinforcement, inaccurate positioning, and easy displacement, resulting in low construction efficiency, difficulty in handling, and large material waste.
A rapid positioning device is adopted, which includes a pier top template, clamps, and horizontal and vertical adjustment mechanisms. Through the cooperation of horizontal and vertical adjustment nuts and screws, the positioning mold sleeve is accurately positioned and fixed, ensuring that gas can be smoothly discharged during concrete pouring.
This enables the rapid and accurate installation of the tenon-shaped anti-fall beam embedded parts, reducing material waste, lowering construction costs, improving construction efficiency and measurement accuracy, and reducing manual labor intensity.
