What Are The Installation Inspection Contents Of Great Wall Bailey Bridge?

Bailey truss is one of the auxiliary bridge of steel basic building blocks. The combination forms, it can be used to assemble into a number of different components and equipment. Bailey bridge is so far, the wider application of popular a kind of bridge structure, bailey truss has many advantages, product structure is simple, easy to transport and erect fast, break down easily. Bailey truss at the same time also has a large carrying capacity, the structure rigidity, fatigue resistance, and many other advantages.

The design of Bailey bridge mainly meets its function, safety, economy, convenience and so on. Could berea, in the construction of the bailey beam to the first on the land or set-up good pier has good according to the size of each group of assembled, and then transported to the construction site for installation. In order to ensure that the axis of Bailey bridge does not deviate, the position of Bailey beam must be determined after laying out the line. Bailey beam after the installation is complete, need to welding positioning block and clamp, and screw to fixed. After assembling the Bailey beam, it is necessary to lay the transverse distribution beam. Through the scene to berea could berea erection construction and use process of tracking, it can be seen that the characteristic of its fast and convenient, saves time limit for a project, installation of splicing is also easy to operation can adapt to a variety of complex environment, an indispensable role in the engineering construction.

The steel frame structure of Bailey steel bridge is easy to rust. In order to avoid the bailey bridge steel rust, people will often for steel bridge maintenance. Therefore, regularly perform every quarter to bailey piece of steel bridge in antirust paint maintenance, key step is to ensure that the service life of highway Bridges, wanna do. The check content is as follows:

1. Check the various pins, anchor bolts, load-bearing beam clamps and impact resistance support rods of The Bailey piece to see whether the assembly line is complete, whether there is artificial damage, whether there is a loosening problem, in order to ensure the safety of entering.

2, phase inspection of Bailey Steel bridge highway bridge has uneven foundation settlement, if found, it should be solved immediately in many ways.

3. Apply vegetable oil around the pin to prevent precipitation from entering the high-temperature fan. Apply vegetable oil to the exposed wire mouth of all anchor bolts to prevent corrosion.

4, often accurate measurement of the span of the highway bridge stiffness, to see if there is an increase in the rate of stiffness should be and pin and pin hole damage into this.

5. Check whether the road surface is cracked, deformed or uneven, and replace it when necessary.
