Construction survey points for long-span suspension bridges of suspension bridge manufacturers
The equipment produced by the suspension bridge manufacturer has strong amusement and ornamental value due to its good height advantage. Standing on the suspension bridge to avoid surrounding obstructions, the entire scenic spot will be seen at a glance, bringing a strong impact and visual experience. . The editor of Wanrong Machinery found that the larger the span, the better the experience will be, but for the long-span suspension bridge, more details should be paid attention to during construction.
The large-span equipment engineering built by the suspension bridge manufacturers is more complicated, so it is necessary to repeatedly measure the mileage. The plane position of the main cable end point of the equipment during construction has been determined by the main cable and the loose cable saddle, so its vertical plane has also been determined. In the case of natural hanging, the horizontal distance from the fixed mileage position to the known control point will not vary with Changes, so the operator can control the elevation of the fixed mileage position to achieve the measurement purpose.
In order to accurately measure the elevation of the reference cable strand, a prism setter can be used to place it above a symmetrical position through mechanical processing. This will save a lot of work for the measurement and combine the actual measured value and the design value. In comparison, the adjustment work is better.
The above is the introduction of survey items in the construction of long-span equipment by suspension bridge manufacturers. I hope it will be helpful to everyone. For more questions, please contact Xinxiang Wanrong Machinery Co., Ltd. We will reply you in time.
