Problems in installation of Jiangmen bridge and conduit
2020-07-10 594
Jiangmen bridge line pipe summed up some problems according to the daily equipment of construction brothers. Assuming that the following situations can be avoided, most errors in equipment process can be avoided. Welcome to our lively comments! 1. The whole length of metal cable tray and its bracket is not solidly grounded (2 places); 2. The elastic joint is not set according to the standard requirements; 3. The cable tray and bracket are not fixed, and the bridge bracket is not grounded jumper;

External causes of aging of Jiangmen Bridge
2020-07-10 692
The cable tray is mainly insulated by the outer layer of the cable. If the protection is not good, the external gas will be corroded for a long time, the insulation function will gradually decline, and the aging, embrittlement or falling off will not play an insulating role. The insulation on the outside of the cable is made of plastic and rubber. Sometimes aging is found. What is the reason? Then, this small series of problems of Jiangmen bridge are analyzed. 1. The insulation is affected by ti

Matters needing attention in welding of Jiangmen Bridge
2020-07-10 692
The construction site is the primary consideration of bridge equipment welding. Because the main girder has a certain temperature difference, camber, warpage and horizontal bending will change. Therefore, when welding in the workshop, it is better to choose the equipment Jiangmen bridge, so as not to form too big temperature difference. Bridge inspection should be carried out in the morning or at night. The orientation of the pad also affects the equipment and welding of the bridge. Because the

How to care for the passivation film effect of Jiangmen bridge pipe
2020-07-10 562
Generally, most of the equipment we use is of special structure, so the effect is not so strong. Therefore, we need to pay attention to avoid the oxidation phenomenon of the equipment and adopt corresponding measures to control it. Generally, when this happens, passivation or pickling process is mostly used to avoid oxygenation, so that the anti-corrosion function of C can be advanced. It can be seen that this method is still very important and plays a key role. In general, we need to choose thi

How to maintain Jiangmen bridge pipe
2020-07-10 623
Daily maintenance: use clean soft cloth to wipe surface dust regularly. Do not use wet cloth or hard objects to wipe Jiangmen bridge surface and mirror glass. Avoid contact with acids, alkaline chemicals and greasy substances. Regular repair: generally, it can be repaired once a quarter. After wiping the dust on the surface with a soft cloth, wipe it evenly with a special polishing wax, and then wipe the surface with a clean soft cloth. Hardware accessories and metal handle can be wiped with les

Now, the profit margin of cable tray is gradually tightening, which is closely related to the price rise of raw materials. Therefore, in order to complete the better development, it is necessary to carry out some technological innovation, such as forward carrying ability. Next, Jiangmen bridge to the following three common cable tray said. 1. The structural strength of steel cable tray profile is higher than that of general plane plate. Jiangmen bridge generally adopts mechanical pulling or limi

1) Admission direction: according to the construction layout plan, combined with the setting of air-conditioning pipelines and electrical pipelines, it is convenient to repair and the density of cable route to recognize the good route of Jiangmen bridge of Huixian line. Indoor, it should be erected along the wall, column, beam and floor of the building as far as possible. If the inductive pipe gallery is needed to be used, it should be erected in parallel above one side of the pipeline, and d
