Precautions when installing the Bailey bridge

1. The management, inspection, training and supervision of on-site personnel should also eliminate the problems and potential safety hazards on site in advance.

2. Some construction standards should pay more attention to: First, pile foundation: Generally, single-row piles require axis deviation ±125px, and group piles require axis deviation ±250px. When checking, use a total station or theodolite plus a rangefinder to check the stakeout point in the middle of the pile of the construction unit, and then use a small steel ruler to measure the position of the middle of the pile. The second is that the axis of the cap (tie beam) is offset by ±15mm. When checking, you can first measure the middle position of the bearing platform (tie beam), and then check with a total station or theodolite plus a rangefinder. The data obtained can be used as the error value. The third is the offset of the axis of the column and pier cap by ±10mm. When checking, you can first measure the middle position of the column and pier cap, and then check with a total station or theodolite plus a rangefinder. The data obtained can be used as the error value. Fourth, during the supervision process, the construction unit must be required to conduct self-inspection first and declare the self-inspection data, especially the self-inspection data of the construction unit of the pile site, and the inspection data of the pile site must be strictly reviewed. Generally speaking, the pile position is accurate, and there is less overshoot in the construction of the other lower part.

Every project needs detailed control. Only when the preliminary preparations are done can the work proceed in an orderly manner.
