Concrete steps and content of steel temporary bridge construction

Temporary steel bridge is a temporary bridge built according to engineering construction and transportation needs. When crossing deep valleys and valleys in mountainous areas, or when the water and land transportation on both sides of the bridge cannot meet the construction and transportation requirements, temporary bridges need to be constructed.

Generally, it has the characteristics of simple structure and low cost, but it should be safe and firmly meet the requirements of engineering construction and transportation. Generally, the construction process of constructing temporary bridges is called temporary steel bridge construction or engineering. The purpose of this project is to assist in the completion of the construction of the main bridge and serve as a temporary substitute for the main bridge.

The construction process of the temporary steel bridge mainly includes the design of the temporary steel bridge, the preparation of the construction plan, the arrival of equipment and materials, the construction layout, the driving of the log pile foundation, the leveling of sleepers, the laying of channel steel, and so on. After that is the railing installation.

Use Φ200mm round wooden piles to drive into the pile foundation of the bridge pier. The driving depth is determined according to geological conditions. Set up vertical and horizontal scissor supports. The top of the stake is covered with sleepers and fixed with grab nails. Laying channel steel in layers makes the whole structure safe and stable. Railings are installed on both sides of the bridge deck. The pile foundation of the temporary steel bridge is driven by circular wooden piles with a diameter of Φ200mm and a length of 8 meters. During the construction process, first put the prepared wooden piles into the river, use a ship-type pile driver to lift the wooden piles with steel wire ropes, adjust the angle of the frame so that the wooden piles are perpendicular to the river surface, and then move them before driving the wooden piles. It is moved to the position of the bridge pier. The penetration depth is mainly controlled by penetration and penetration depth to achieve the design bearing capacity.
