Common quality problems in the key control of water engine room - construction control is not in place
1. There is leakage in the roof and side walls of the water machine room, the wall surface is uneven, not clean, cracks, hollow drums and other defects, the yin and yang angles are not straight, and the treatment behind the pipeline is not in place
2. There are sundries such as waste brackets, expansion bolts, junction boxes and so on the wall
3. There is no drainage ditch in the water machine room, and the depth, slope and width of the drainage ditch do not meet the design requirements
4. The layout of the pipeline is unreasonable, the inlet and outlet pipes are not lined up, the identification is not clear, and the installation position of the pressure gauge and valve is unreasonable
5. The rubber and plastic insulation is not fully adhered to
6. The arrangement of brackets and equipment is unreasonable
7. The vibration reduction measures of the equipment are incomplete or the settings do not meet the requirements

"Code for Acceptance of Construction Quality of Building Electrical Engineering" GB50303-2015
Code for Construction Quality Acceptance of Building Water Supply and Drainage and Heating Engineering GB50242-2002
Technical Specification for Fire Water Supply and Fire Hydrant Systems (with Explanations) GB 50974-2014
Standard Points:
The pipe is clean, straight, pollution-free, color-free, undamaged, and the paint is complete, uniform and bright
The layout of the pipeline is reasonable and beautiful, the upper and lower are staggered and the spacing is uniform, the inlet and outlet pipes are lined up, and the installation position and elevation of the pressure gauge and valve are unified
The lighting of the water machine room should be located in the lower part of the pipe, without blocking, and the illumination should meet the design requirements
Standard Points:
The color separation of the pipeline is complete, the sewage pipe is black, the air conditioning cooling pipe is blue, the fire hydrant and spray steel pipe are red, and the white arrow is marked according to the flow direction of the medium in the pipeline, one every 5m
The bracket is firm, the pipe contact is tight, the elevation of the bracket is consistent, and the support and hanger are rust-proof in place
Standard Points:
The temperature of the construction environment should not be lower than 5 °C
When the glue is applied, it must be fully applied inside the insulated pipe shell and on the outer wall of the pipe. When bonding the insulation material, the debris, dust and oil on the surface of the pipe must be cleaned
The interface and all the gaps of rubber and plastic insulation materials are required to be tightly bonded with rubber and plastic special glue
The insulation material of valves, filters, flanges, etc. is the same as that of the pipeline, and the insulation thickness is the same
