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:

　　，维护管和接线盒必需阻燃，外观不得变形和损坏。

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

　　第二，同一根导线必需穿入同一根根管，但导线总数不应超越8根，导线总面积不应超越导线总数的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，电线与煤气、暖气、热水管道和弱电管道的平行间隔应小于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：穿线管转弯应大于1200。管道内不得有接头。一切接线头堆叠，并排入接线盒。

　　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：电源接线时，应保证电源设备的大输出功率；同一电路接线也应分色，直径相同。毕竟，装饰是手工的。鼓舞总是好的。贵阳市装修业主对装修验收有一点理解，为了避免装修施工人员的投机、混杂，防止今后不用要的费事。

　　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.
