1) Confirmation direction: according to the layout plan of the construction, combined with the setting conditions of air-conditioning pipelines and electrical pipelines, convenient repair, and the density of cable route, the best route of Jiangmen bridge of Huixian line is recognized. Indoor, it is necessary to erect along the wall, column, beam and floor of the building as far as possible. If it is necessary to use induction pipe gallery, it should be erected in parallel above one side of the pipeline, and downlead should be considered If there is no other pipe support for borrowing, it is necessary to set up a prop by itself.
2) load Accounting: calculate the cable component per unit length on the vertical section of the trunk line of the convergence line bridge.
3) draw the plane and section drawings of cable tray, and draw the space diagram of local parts, and list the data sheet.
4) equipment recognition method: according to the setting conditions of the site, the fixed method of the bridge is recognized, including suspension type, vertical type, side wall type or mixed type. The connectors and fasteners are generally supplied in a complete set. In addition, the corresponding revision is selected according to the bridge structure.
5) the width of the cable tray: the type and standard of the cable tray, the length of the bracket arm, the length and distance of the pillar, the width and number of layers of the bridge are recognized according to the number of cables laid, the diameter of the cable and the distance between the cables.

How to renew the damaged Jiangmen Bridge
Jiangmen bridge plays a very important role in the power industry. The bridge is widely used. The application environment of bridge products in bridges is sometimes bad. The bridge will inevitably be damaged in operation. Usually damaged bridges need to be replaced. Pay attention to safety when replacing bridges. The material of cable bridge is mostly steel. If exposed to various environments for a long time, it will inevitably suffer from corrosion, rust, high temperature burning damage and ext
What are the maintenance steps of Jiangmen bridge and pipeline
With the continuous development of social economy, the use of bridge in Guizhou is also increasingly extensive. As for the bridge, do the usual maintenance and protection work, which can well extend its life. Let's take a look at what protection operations there are. 1. Rust treatment: generally, two layers of chlorosulfonated primer are used for two-part derusting of cable tray. The quality of surface derusting directly affects the life of anti-corrosion engineering. Generally, the field derust
What are the installation requirements for Jiangmen bridge conduit
1. In the engineering design, the bridge should be comprehensively considered according to the economic rationality, technical feasibility, operation safety and other elements, and then the optimal scheme should be confirmed, which also needs to meet the requirements of installation, maintenance and cable placement. 2. When the bridge, trunking and its supports and hangers are used in corrosive environment. Anti corrosion treatment shall be adopted, which shall meet the requirements of engineeri
How to transport Jiangmen bridge and pipeline
Jiangmen bridge is usually customized by the manufacturer. As it is a kind of unconventional product, generally only the manufacturers in the provincial capital will be transported remotely. In the process of transportation, due to the road conditions and the quality problems of the bridge itself, the products will have a certain degree of wear and damage. How to transport the cable bridge? 1. We should ensure the quality of the cable bridge. The quality can ensure the bearing capacity of the br
