Do you know all the details of the construction steps of fire fighting engineering?

Prepare to set up project team before construction of 1. fire protection works

1, the project department to understand the project overview, drawings review, review the best construction plan, according to the civil construction plan to determine our time limit for a project, schedule and employment plan;

2, the development of material plans, according to the progress of the project and construction drawings, reasonable to provide the actual amount of on-site plan, copy to the procurement department;

3. The project supervisor shall contact the construction and supervision unit to handle all commencement procedures (submit qualification, organization design, commencement report, etc.);

4. Organize construction personnel to enter the site for safety education and technical disclosure.

2. construction process

1. Quality and Safety Department shall inspect the whole process

(1) Fire water system

Organize project members → be familiar with drawings → construction qualification, organization design, start-up report, safety education, technical disclosure and plan preparation → steel pipe entry inspection → reserved hole size verification → support and hanger fabrication and installation → pipeline rust removal and oil brushing → main pipeline installation → steel pipe inspection batch and concealed works inspection → branch and piping installation → valve and fire hydrant entry inspection and valve strength tightness test → valve and fire hydrant installation → valve and fire hydrant batch inspection → nozzle entry inspection application → pressure stabilizer, water pump and water pump connector → Installation of pressure stabilizing device, water pump and water pump adapter → Inspection approval of water pump adapter → System debugging → Inspection of pipeline strength and tightness test, pipeline cleaning and disinfection record, fire hydrant test record, pipeline water supply test → Inspection of divisional (sub-divisional) project → Inspection of sub-divisional project → Production of water pump linkage debugging → Project self-inspection → Rectification → Self-inspection qualified → Inspection by inspection company → Inspection by fire department → Transfer of project → After-sales service

(2) Automatic fire alarm system

Organize project members → be familiar with drawings → construction qualification, organization design, start-up report, safety education, technical disclosure, preparation of plan → steel pipe and bridge approach for inspection → steel pipe laying (exposed steel pipe fire prevention treatment) → steel pipe and bridge inspection batch, concealed and sub-project inspection → threading wire → bridge installation and bridge internal wiring → cable approach for inspection → threading wire inside the pipe → wiring (solder) → threading inspection batch inside the pipe and sub-project inspection → line insulation test → insulation resistance test record inspection

→ Equipment mobilization for inspection → Equipment base installation → Equipment installation → Equipment installation inspection batch and sub-divisional and sub-divisional works for inspection → System commissioning → System commissioning sub-divisional works for inspection → Point position layout making → Project self-inspection → Rectification → Self-inspection → Inspection → Inspection by Inspection Company → Inspection → Acceptance by Fire Department → Project handover → After-sales service.

Self-inspection of 3. Engineering Department

1. Inspection basis for fire fighting water system: DB64/T404-410-2005 "Code for Quality Inspection and Evaluation of Fire Fighting System" and GB50261-96 "Code for Construction and Acceptance of Automatic Sprinkler System". Inspection items: fire water pump, water pump adapter, outdoor fire hydrant, water delivery pipe network, pressure, main equipment, fire water tank, air pressure water supply device, alarm valve group, hydraulic alarm bell, water flow indicator, nozzle and system linkage test.

2. Inspection basis for automatic fire alarm system: DB64/T404-410-2005 "Code for Quality Inspection and Evaluation of Fire Protection System" and GB50166-98 "Code for Construction and Acceptance of Automatic Fire Alarm System". Inspection items: piping, system wiring, installation of detectors, manual alarm button, fire alarm controller, floor display, fire control room and system linkage test above two items need to pass self-inspection.

4. declaration inspection

1, testing company testing;

2. Test qualified;

3. Apply for acceptance by fire department;

4. Acceptance is qualified.

5. acceptance qualified

1, the user system operation training trainees signed confirmation;

2. Hand over relevant engineering data, prepare final accounts data, and cooperate with the Finance Department to do a good job in the recovery of engineering funds;

3. Establish project after-sales service files to track users.
