Bridge body transporting and locating method

Abstract

The invention relates to the field of bridge construction engineering, in particular to a bridge body transporting and locating method. L-shaped hanging hole positions are oppositely arranged at the two ends of a bridge body mounting position; the two ends of a bridge body are inverted L-shaped corresponding to the shape of each of the hanging hole positions; temporary bridge piers are oppositely arranged under the bridge body mounting position; the bridge body is transported to a specified position by utilizing a flat barge; first hydraulic equipment is mounted under the bridge body; second hydraulic equipment is arranged on the hanging hole positions or the temporary bridge piers; the first hydraulic equipment lifts and falls back the bridge body to the two ends to erect on the second hydraulic equipment; the second hydraulic equipment falls back the bridge body to the two ends to erect on the hanging hole positions again. The technical scheme adopted by the invention has the advantages that the flat barge is large in loading capacity and can load any tonnage of the bridge body; a water transporting mode is more suitable for the erection of the bridge body positioned in the middle of a bridge; the hydraulic equipment can better master the accuracy of a bridge falling position, so that the deviation of the bridge falling position is reduced; the construction safety is high.

Description

technical field [0001] The invention relates to the field of bridge construction engineering, in particular to a method for transporting and placing a bridge body. Background technique [0002] Modern bridges across rivers and rivers are generally hundreds of meters long, and some large bridges are as long as one kilometer. The longer bridge spans several bridge posts, and each section of the bridge body is erected on the piers on both sides, connected by steel bars and poured with concrete to form a stable structure. The construction of the bridge involves the need to transport and erect the bridge body to the pier. In the existing technology, the bridge body is generally transported from the land to the bridge construction site by a flatbed truck after the factory has finished processing and testing, and then the bridge is hoisted by a crane. The body is erected on the pier, which has the following disadvantages: [0003] 1) The crane or floating crane is limited by the ...

AI Technical Summary

Problems solved by technology

[0003] 1) The crane or floating crane is limited by the length of the boom. The crane is lifted from the land and cannot be applied to the bridge body with a wide river surface, while the floating crane is lifted from the water surface and cannot be applied to the bridge body with a narrow river surface; 2) The crane is in the Due to the long distance during hoisting, the accuracy of the drop beam position cannot be well controlled, resulting in position deviation of the drop beam; 3) The cost of the crane entering and leaving the site is high and the economy is poor; 4) Due to the high suspension of the crane arm, the construction safety is poor, prone to accidents
