Decoration owners usually see cracks in the walls. It may be that after the pipeline layout is completed, putty powder will be used to plug it, so that in the future, the use of micro-vibration in the middle of the pipeline will make the surrounding walls present such cracks. In fact, the use of Guiyang putty powder to stop the simple disposal of pipeline openings will not only crack the wall, but also easily damage the pipeline. The standard method is that the strength of the pipeline can be guaranteed only by sealing the pipeline with cement which is different from the original structure. Of course, today's construction technology also uses special pipe plugging mud. The plugging mud must be environmentally friendly and solvent-free. This new information cannot be solidified for life. It has good tracking effect on thermal shrinkage, cold shrinkage and mechanical deformation of viscous objects, and can effectively avoid wall cracking in use. In the acceptance of gas pipelines, we can grasp the following points:

　　，維護管和接線盒必需阻燃，外觀不得變形和損壞。

　　First, the maintenance pipes and junction boxes must be flame retardant, and the appearance should not be deformed or damaged.

　　第二，同一根導線必需穿入同一根根管，但導線總數不應超越8根，導線總面積不應超越導線總數的40%。

　　Secondly, the same conductor must penetrate the same root canal, but the total number of conductors should not exceed 8, and the total area of conductors should not exceed 40% of the total number of conductors.

　　第三，電線與煤氣、暖氣、熱水管道和弱電管道的平行間隔應小于300 mm。

　　Thirdly, the parallel interval between the electric wire and the gas, heating, hot water and weak current pipes should be less than 300 mm.

　　第四：穿線管轉彎應大于1200。管道內不得有接頭。一切接線頭堆疊，并排入接線盒。

　　Fourth, the turn of the threading pipe should be greater than 1200. There shall be no joints in the pipeline. All terminals are stacked and arranged side by side in the junction box.

　　第五：電源接線時，應保證電源設備的大輸出功率；同一電路接線也應分色，直徑相同。畢竟，裝飾是手工的。鼓舞總是好的。貴陽市裝修業主對裝修驗收有一點理解，為了避免裝修施工人員的投機、混雜，防止今后不用要的費事。

　　Fifth: When connecting the power supply, the maximum output power of the power supply equipment should be guaranteed; the same circuit wiring should also be color-separated, with the same diameter. After all, decoration is handmade. Encouragement is always good. Guiyang decoration owners have a little understanding of decoration acceptance, in order to avoid speculation and confusion of decoration construction personnel, to prevent unnecessary trouble in the future.
