【 Weak current College 】 indoor comprehensive pipeline construction site coordination and control

Indoor electrical comprehensive pipeline overview
(1) ELV pipeline include: high-voltage, power, lighting, telecommunications, broadcasting, TV, building automation, security, Elevator, Internet, strong or weak electric control system of pipelines, conductors pipes, cable tray, trunkings, various kinds of boxes (boxes).
(2) air conditioner, water, storm water, sewage, water, heat (steam, hot water), gas, fire, pressure pump, etc.
(3) pipeline laying channel has strong electric shaft, weak current shaft, and drainage and thermal shaft, public sidewalk ceiling, the device layer etc pipeline distribution-intensive, pipeline layout space is small, to construction unit pipeline laying great difficulty, if the professional construction units do not consider the space geometry, secretly for pipeline installation, box, carton, Tad rework quantity big, will cause a lot of manpower and material resources, financial resources and waste, and missed deadlines.
Indoor Professional tie comprehensive pipeline
(1) electrical and civil engineering professional. First, followed by electrical construction year, month, year of construction progress plan professional project construction plan, when the civil construction plan changes, and electrical engineering should do the corresponding construction plans, guarantee not drag and civil construction back.
(2) pursuant to the civil construction schedules, the timely adjustment of engineers and technicians and construction personnel, preparation of adequate materials and spare parts, accessories, etc., to meet construction requirements.
(3) civil construction in time, the implicit target will not be guaranteed due to the embedded pipelines, boxes, cartons, reserved hole failed to timely pre-screen, implicit checkout delays resulting concrete casting.
(4) cooperate with the civil construction site security work, strict adherence to the safe production of the relevant laws and regulations.
(5) the electrical construction units follow unified command, unified by a full-time staff, coordinating construction scheduling command.
(6) pipeline construction principles; ventilation ducts in advance, no pressure pipes for pressure pipeline pilot, tubular let big pipe.
Indoor comprehensive pipeline construction control
(1) various electrical, pipeline intensive should detail drawing or plan of the integrated pipeline labelled with pipeline, slope, pipe carrier type, number, size, location, elevation, coordinates all professionals pursuant to such parameter to field measurements to verify that the review confirmed as correct before construction. On the good from the construction of the unit should be educated or punishment.
(2) pipe hangers, particularly large-diameter pipe or ventilation ducts, there should be concrete construction plan, clear loads, fixed bolt lata meets the requirements, a large pipeline of dynamic load shall be determined by designers for accounting and construction.
(3) of the pipe diameter is large, dynamic loading forces, if the lifting roof, electrical designers determine fixed bolt load-bearing load, you should consult with architects, roof is able to withstand pipeline weight and dynamic loads of impact, certified meet design requirements, and construction. If the designer has a measure does not meet the requirements, the need to take remedial measures program, confirm the feasible after construction, the construction is not allowed.
(4) the professional pipe hangers should separate fixed the pipeline, not allowed to use other professional pipe hanging bracket.
(5) control of the level and pipeline verticality, Actinomyces, hanging lines require errors in existing national standards and norms in the stipulation scope beyond the deviation should be promptly adjusted qualified.
(6) of the control pipe interface parts, such as Pittsburgh, grooved, welding, socket interface (cement twisted mouth, rubber ring interface), flange connection, etc. should be consistent with existing national standards and norms.
(7) water supply and drainage pipe PVC-u (UPVC) there are two ways to connect: Socket-bonding and thread variable connector, the pipeline closed water leakage test must not occur.
(8) wire pipe interface with welding, wire crimping, withhold connection, threaded connection, pipe and tube connection, pipe connection with cartridge boxes, tubes and connections and trunkings, should be consistent with existing national standards and norms.
(9) trunkings, bridge and other interfaces, PE protective line installation should comply with the provisions of existing standards and specifications.
(10) pipeline laying long vertically or horizontally, depending on the construction of the acceptance of requests for additional compensation.
(11) expansion joints (deformation of joints), according to the specification provides for an increase in the compensation measures.
(12): pipe pipeline condensation water, summer around product pipeline and of dew drop down, hence the need to have the condensation heat preservation measures, inspection of insulation types and sizes to choose whether or not qualified, the insulation protection layer should be strict, installed securely.
(13) indoor plumbing and gas piping interface elevation exterior locations connected with flange connection and socket connections, welding, pipeline construction in the outdoor complex, mutual communication wall and wall, a pipe length is normally reserved for 30 ~ 50cm, easy to interface construction and maintenance. The casing and the gaps between the cross tube blockage from an outside line construction professionals.
(14) the professional pipeline inspection, shall be determined by the owners, supervision, design, construction units on the quarantine order confirmation shall prevail.
