Project general situationJPL 2 660 MW power station #1, #2 boiler steel structure provided by Harbin boiler factory, adopt the structure which is separate from main workshop.Roof steel structure combine by ceiling girder, secondary beam and surface support, come into a rigid surface. For here adopt A,B,C,D,E four row ceiling girder, the length of span is 28m, A ceiling girder divide in three parts, E ceiling girder divide into two parts, the main ceiling girder of B、 C、D have a big capacity、wideness span more, adopt the stop log style. 3.

Homework conditionThe main equipments delivered condition Ceiling girder arrived in order remarkarea, force emerge:a. first class panel(420 V power supply)b. Oxygen, acetylenec. The spot fire fight device with temporary pipe linePreparation condation for erection Environment:a. The construction road is unimpeded.b. The site tool building, temporary deposit area for ceiling girder. And the deposit area neat and solid.Work period 2010.05.232010.06.10Manpower The technique is 2 people, the safety be 2 people, the fire Han be 2 people, the electric welding be 4 people, install 30 people, heavy 12 people, operation 6 people, 2 electricians, the work be 8 people.Machine The 350 t track mourn(CC2200) one set, the 75 t tower mourn(FZQ1650) one set, electric welding machine 2 setWork tool electric wrench, grinding machine, chain block,big hammer, pry stick, line to fall to, the kind be blunt, live wrench, spring coil to call, 50 sling, 22 sling etc.Measure tool Spirit level, level instrument, theodolite, 100 m tape measure, 50 m tape measure, 2 m steel plate Chinese foot.etcMaterial Wood the plank, square wood, hemp cordage, level rope, soft climb steps, from the lock machine, from lock machine rope, guard rope etc5. Homework project5.1Construction schemeAccording to each ceiling girder weight and relevant data, calculation it and get result, upper parts of D、C、B ceiling girder weight is more, proceed to lifting it by 350 t track to mourn(CC2200) and 75 t the tower mourn(FZQ1650), and it will be lifted at furnace inside area. 3450t crawler crane (CC2200) adopt principal arm 72 meters and assistant arm 30 meters and 72 meters and assistant arm 42 meters SWSL work condition and arrange right side of furnace, the 75 t tower arrangement on the left side of furnace. Others ceil girder lift by 75t tower crane alone. 5.2 The construction work preface flow chart5.3 The construction prepare a work preface card Number：001Construction preparationCeiling girder and secondary beam installTotal lineation for steel structureLineation on the furnace roof steel structure1. Summarize: According to construction mission, before working well item an opening of each item preparation work. 2. Operation methodSerial number and step nameMain homework method and operation requirement quality requirement1. Acquaint with drawingTotal worker who will attend construction should know the drawing & techno ledge well, explicit construction mission, quality standard. Know well about the machine work condition.2. Work tool preparationThe construction power supply connect line, instruments, measure, sling for lift in readiness1.
