Dear friends, are you still worried about how to ensure the quality of air duct construction? I believe this is also the concern of consumers.
First of all, in order to make the construction effect better, we should formulate some strict implementation measures. One point is to draw the construction drawing and organization design scheme according to the construction requirements and the construction site environment before construction, and operate in strict accordance with the construction drawing and organization design scheme during implementation, which cannot be changed at will.
Second, the quality of materials to be used in construction shall be inspected. If there is no problem, they can be used in construction.
Third, the construction shall be carried out in strict accordance with the relevant national travel regulations, so as to ensure the integrity of the construction.
Four points, technical guidance should be given to the personnel in construction, so that they can master the essentials in construction, carry out field measurement, record relevant measurement data and improve the quality of construction.
Five points: the construction shall be carried out according to reasonable procedures, and the problems found in the inspection shall be repaired in time and given relevant guidance.
Six points, improve the reward and punishment system in construction, and reward the conscientious constructors under the condition of ensuring the integrity of each constructor, so as to encourage everyone to pay attention to the overall quality of construction.
After construction, relevant personnel shall carefully check the construction records, put forward and solve the problems in time, and conduct disclosure after confirming that there are no problems.
The use of ventilation pipes in modern buildings is becoming more and more scientific. In the construction process, the general principle is that small pipes give way to large pipes: small pipes are easy to bend, and the cost is low. This principle is the avoidance principle.
Small tube makes big tube: small tube is easy to bend, and the cost is low.
The branch pipe gives way to the main pipe: the diameter of the branch pipe is generally small. See 1 for the reasons for avoiding the ventilation pipe project. In addition, the influence scope and importance of the branch pipe are not as important as the main pipe.
Pressure pipe to non pressure pipe (pressure flow pipe to gravity flow pipe): the non pressure pipe (or gravity flow pipe) changes the slope and flow direction, which has a great impact on the flow.
The normal temperature pipe is replaced by the high (low) temperature pipe (the cold water pipe is replaced by the hot water pipe, and the non insulated pipe is replaced by the insulated pipe): the exhaust shall be considered when the ventilation pipeline project is higher than the normal temperature; If it is lower than normal temperature, anti condensation and thermal insulation shall be considered.
Water supply pipe and drainage pipe: in addition to the above three reasons, the diameter of the drainage pipe is usually large and there are many impurities in the water.
Low pressure pipe to high pressure pipe: high pressure pipe has high cost and high strength requirements.
Gas pipe makes water pipe: the power consumption of water flow is large.
General ventilation pipe: large volume, difficult to bend.
Metal pipe allows non-metallic pipe: metal pipe is easy to bend, cut and connect.
Small valves make more valves: installation, operation and maintenance of Shanxi oil fume purification system shall be considered.
