Common water and electricity cut-off phenomenon read less do not lie to me

"I read less, you do not lie to me", for the decoration of this matter, not only have to worry about the quality of decoration, but also the embankment do not be the decoration company and decoration workers "pit." A lot of decoration workers are outsourced by the decoration company. Occasionally, the quality of jobs is uneven, and the phenomenon of cutting corners and materials is frequent, especially hydropower reform. Today we will look at the jerry-building cuts in hydropower projects.

First, please don't save money for me.

In the formal construction of waterways, various types of small pipe fittings such as bridge bends, straight throughs, and tees need to be used to realize the specification of pipe laying. In the hands of bad construction teams, it is very easy for water pipelines to turn around without using interfaces. Intersections with wire ducts do not use bridge bends. Although this will save time, it will have a great impact on the quality of the pipeline and its subsequent construction.

Second, the "overload" hazardous wires also do so

According to the electrician's construction specification, the section of conductors placed shall not exceed 30% to 40% of the pipe. In order to steal work, some construction masters often put multiple wires into the same pipe. This can easily cause insufficient gaps in the tube, so that the heat generated when the wire passes through a large current in the line tube cannot be dissipated, and thus there is a risk of aging and fire.

Third, are you really confused?

Hot water pipes need to withstand thermal expansion and contraction, and the performance requirements for materials such as high temperature resistance are higher than those of cold water pipes. Hot water pipes are generally more expensive than cold water pipes. Generally blue is a cold water pipe and red is a hot water pipe. In the construction, all hot water pipes can be used, or normal hot and cold water pipes can be used. However, some unscrupulous construction teams may use cold water pipes as hot water pipes. Although this is not a problem at the moment, it is prone to leakage of cold water pipes in later stages.

Fourth, want to pass the box must be picked up

When the wires are laid, there may be cases where they are not long enough and need to be wired. Some construction teams will directly insert the tubes without passing through the box after the line is completed. To know that the interface is often the most prone to problems, the practice of keeping the thread in the tube will make repairs very difficult when problems arise later.

Fifth, do not learn to "naked"

When the supervisor inspects the circuit, after discovering that the circuit of the top lighting of the restaurant has been changed, the newly laid wire is buried directly on the top surface without the protection of the PVC sleeve. The insulation of a long wire is easily corroded and a short circuit can occur.

Wires are laid on the wall surface and must be threaded into the PVC casing for protection. If it is the top surface or the load-bearing wall cannot be grooved, the yellow wax tube must be used to protect the wires in order to bury the wires.

6. What to do if accidents happen on the same bed?

In the construction, strong electricity (such as lighting wires) and weak electricity (such as telephone lines and network cables) are placed in a pipe or box, and a pipe or box is placed less, saving time and labor. However, in doing so, there are interferences when making a call or surfing the Internet. At the same time, too much threading in the same pipe also creates a risk of fire.

Seven, milk tea, I only want to music the United States

“Reducing materials” does not only mean using less materials, but also using inferior materials instead of high-quality materials to earn the difference. In the waterway reconstruction, the pipeline is less concerned because the owners will pay more attention to it. However, due to the small size of the pipe fittings and the large number of pipes used, the owners did not pay attention. When they encountered bad decoration companies or construction workers, it was easy to connect the water pipes with poor fitting pipes. To know this approach, it can easily lead to failure at the interface.
