More and more owners have realized that if the hydropower reform does not follow the standard construction, it will bring various hazards to the future life. However, most people only pay attention to whether the quality of wires and pipes is qualified, and neglect the details of the slotting and sealing of hydropower reforms. For example, if the workers are a little lazy, do not fill the surface of the sealing groove, and pay attention to maintenance on the cement layer of the channel, these will not only affect the construction quality of the next process, but also cause hidden dangers for the owner's future life.
Owner: Ms. Zhang
1. The slot wall is too smooth
Description of the problem: The outer wall of the balcony has been previously affixed with ceramic tiles. When the construction workers pre-embed a balcony waterway, the outer wall is directly grooved. In order not to destroy the original wall tiles, the construction personnel cut the two sides of the pipe trough very smoothly, which easily leads to the cement mortar sticking loose when the trough is sealed, and will easily fall off in the future.
There is no color separation between the ground and the zero line, and it is difficult to repair the line in the future.
Rectification plan: The groove wall surface must retain a certain degree of roughness, cement mortar will be "patched." The owner can ask the worker to chisel the wall of the pipe with a chisel to avoid the pipe wall surface being too smooth.
2. Grooves are not evenly grooved
Description of the problem: When the supervising engineer inspected the wire ducts on the wall of the living room, he noticed that there was still a significant pit in one of the sealed ducts. The supervisor said that if you put the putty directly here in the future, you have to fill in a thick layer of putty, and once it is pasted, the sub-layer is not easy to fall off.
The distance between strong and weak electricity is too short and weak electricity is vulnerable to interference.
Reorganization plan: Workers are required to re-fill the pits with cement mortar.
3 cracking of the slot cement layer
Description of Problem: The supervising engineer discovered that the cement layer on the surface of several grooved wire troughs had been cracked. This is because the construction personnel did not wet the cement layer of the wire trough before sealing the trough, and did not pay attention to watering after filling in the cement mortar, resulting in the cement mortar drying too quickly and cracking.
The groove cutting of the groove is too smooth, which may cause the cement mortar to stick loose when sealing the groove.
Rectification plan: Cut out the cracks, re-fill the cement mortar, and cure under wet conditions.
4. Wires are not separated
Description of the problem: Some of the circuits in the site have been laid, but some of the wires are not in accordance with the provisions of the color. For example, both the ground wire and the neutral wire use yellow-green two-colored wires, which makes it difficult to maintain the lines in the future.
There are still obvious pits after the slot sealing, and the putty layer is easy to fall off.
Rectification plan: In accordance with the regulations, the wires to be laid must be distinguished from each other in color. The fire wire should be red, the neutral wire can be a blue wire, and the ground wire should be yellow-green. Nowadays, the hydropower transformation of Ms. Zhang’s new house has come to an end. If the circuit needs to be rectified, the amount of work is large. The supervisory supervisor reminds the owners that they must supervise the construction of the workers according to the specifications before the circuit transformation is completed, and timely rectify the problems once they are found.
5. The distance between strong and weak electricity is too close
Description of the problem: Construction workers connect the outlets in the living room in a row. This seems to be more beautiful. In fact, due to the close proximity of strong and weak electricity, weak signals such as TV signals are easily interfered by strong electricity.
The slot cement layer is cracked. It is recommended to remove the cracks and refill the mortar.
Rectification plan: When laying wires, the distance between strong and weak electricity should be more than 30 cm to prevent the weak signal from being disturbed.

Question Q: My family is doing a waterway reform. Will the water pipe go over the roof and go to the ground? Which method is better?
A expert replied: It is the most common practice for water pipes to go to the ground. It is practical and easy to use. Water pipes can also be used on rooftops. Both have their advantages and disadvantages. Although the pipes used to walk the roof will cost more, it is convenient for future maintenance. If water leakage occurs, the ceiling can be repaired simply by opening the ceiling. Although the pipelines save some pipes while walking on the ground, they require floor tiles for overhaul and the amount of work is relatively large.
Q Q: What is the difference between clear oil and contaminated oil?
A expert replied: The main difference between clean oil and mixed oil is that the performance of the two is different. The clear oil is good at expressing the texture of the wood, and the hardwood texture is mostly beautiful, so the clear oil is mostly used on hardwood. The main performance of the mixed oil is the color of the paint itself and the shadow change of the wood grain itself. The splints and softwood density boards with low requirements for wood can be used.
