1, the construction sequence: Construction scaffolding erection → Security → manual removal facilities erection barrel garbage removal → dismantle all construction scaffolding. 2, the construction method: (1) puts up from the ground to the top of the closed steel scaffolding (1.5 m above the chimney) and after passing the acceptance, artificial began dismantling; (2) manual removal before the vent as a slag tap, using a small excavator slag. (3) construction workers standing on scaffolding, rear seat belt hung on the pipe, using picks, hand hammer from outside to inside the cylinder block by block demolition, so the whole ballast blocks falling from the interior of the cylinder; (4) Do not remove the night operation, slag can be arranged in the evening, which will help during the day to continue the removal. Do not remove the slag and at the same time; (5) Scaffolding with lower construction while reducing the surface, but the scaffolding must always be kept above the work surface from 1.5 to 2 m, in order to prevent clinker flying scaffolding protective layer; (6) oxygen, acetylene bottles placed on the platform, only gas cutting gun construction surface, side edges blown lightning split antenna (truncated length of not more than 1 meter). 3, the main construction technology: artificial removal of 45 m chimney main difficulty is the construction scaffolding erection, which is key to the safety of construction projects. 3.1 floor-fastener construction steel scaffolding erection: Scaffolding for the double scaffolding, erection height of 46.5 meters, 20 meters below the double tube pole, 20 meters above the single pipe pole, erection size: inside and outside the legislature pole center distance 1.05m, pole vertical distance 1.6m, step away from the height of 1.8m, 0.2m from the ground at a set vertical and horizontal sweep shot, efflux pole 0.6m and 1.2m each were set at the height of the longitudinal railing, pole set across six scissors, oblique angle between the club and the ground 45 degrees to 60 degrees, the scaffolding set up outside of the dense mesh safety net. WALL rod frame body structure and barrel to a two-step two-point cross to set up a Rachel, Rachel uses deadlift junction point, the points with the wrong plum-type arrangement, the end portions Rachel points should be strengthened. 4, scaffolding erection steps of: 4.1 before the erection of scaffolding, should do the following preparations: a, materials preparation (1) All pipes are made of scaffolding φ48 × 3.5 steel, weighs less than 25kg each control for easy operation. (2) surface with steel should be straight and smooth, there should be no cracks, scarring, delamination, dislocation, hard bend, burr, indentation and scratch deep channel; pipe diameter, wall thickness, cross-section and other deviations shall comply with the regulatory requirements. The depth of the old steel surface rust, bending degree should meet the specification. All pipes should be painted color. (3) should be used with regular factory fasteners, fasteners should be checked before use, cracks, deformation is prohibited to use, there slippery silk bolts must be replaced. (4) bamboo fence bamboo scaffold board should adopt production, bamboo fence should be intact without damage. (5) All components and parts should be variety, size classification, pushing put neat, smooth, stack space may not have water. (6) All admitted steel, fasteners, scaffold boards must be checked acceptance, substandard products should not be used in this project. b, before the erection of safety and technical disclosure. Construction programs for construction workers should scaffold erection requirements, step by step to set up and use of personnel into the safety technical disclosure. C, clear the ground before the erection of debris, smooth erection site, and drainage flow. 4.2 Erection of a, base mounted: (1) by scaffolding floorplan requirements actinomycetes, location. (2) According to the scene, the pole base with the 12th Yang laid concrete channel directly to aerodromes. (3) Yang shop smooth channel must not be vacant. (4) at 20cm from the ground, set the vertical and horizontal sweep shot. Set sweep shot approach with a large bar and small bar identical to fix the bottom pole, pole shift constraint and settlement. b, rod erection of scaffolding erection sequence is as follows: Sets the portrait sweep shot → pole → lateral sweep shot → Step longitudinal horizontal bar horizontal bar → → The first step in connecting wall bridging rod → → → scaffold railing fence → Article two-step longitudinal horizontal bar → Step horizontal bar. c, pole erection (1) take a long pole top step except the top, the rest of the layers each step must be butt joint fasteners. Pole adjacent docking fastener can not at the same height, stagger distance should not be less than 500mm. Pole verticality deviation over the full height range of not greater than 75mm. (2) Start erection pole, set one every six cross bracing, wall pieces until after the installation is stable, according to the situation before the demolition. (3) When the ride to have constructed points wall pieces, and in the end where the erection pole, vertical horizontal bar, horizontal bar, set the wall pieces immediately. d, the horizontal bar erection (1) longitudinal horizontal bar should be set up on the inside of the pole, its length should not be less than three span. (2) to take a long horizontal bar longitudinal butt fastener connection. Distance docking fastener connection should be staggered, two adjacent longitudinal joint should not be set in synchronization with the horizontal bar across the inside and stagger distance of not less than 500mm in the horizontal direction, each of the joint center to the nearest main node should not be greater than the vertical pole from 1/3. (3) in the same step, the longitudinal horizontal bar should be four weeks post circle, and inside and outside corners with right-angle fastening step the pole fixed, fixed spaced not more than 6m. (4) The primary node must be set to a horizontal bar, with rectangular buckle fastening and non-removal. (5) horizontal bar wall ends to the wall distance should not be greater than 200mm. (6) horizontal bar ends are applied at right angles to the pole fixed fastener. Horizontal bar on the job level at the non-primary node, should be equally spaced scaffold boards according to the required maximum spacing should not exceed a vertical distance of 1/2. (7) Scaffolding must be set vertical and horizontal sweep shot. Sweep shot from the pad 200mm. e, scissors, lateral bracing, wall pieces erection (1) scissors, lateral bracing should vary with pole erection, erection of vertical and horizontal sync to the horizontal bar and so on, in no case shall exceed two-lag. Scissors should be continuously provided on the outer facade along the entire length and height. (2) bridging oblique angle with the ground control lever between 45 ° ~ 60 °, every scissors across the width of not less than four and not less than 6m. (3) Subject to the corner should be located outside the lateral bracing, intermediate 6 is set to join every cross. Lateral bracing should be between the same section, from the bottom to the top was "the" type continuous arrangement. (4) bridging connections in the form of uniform application of the lap, lap length ≥1000mm, and a lap joint on less than two steering connection fasteners; overlapping parts must be effectively connected with the pole. (5) should be the level of the connecting rod is provided connecting member. When the lower part of the scaffolding connection can not be located temporarily at intervals of 10m set bracing erection bracing, bracing must be reliably connected to the scaffold, and should only dismantled even after the erection of the wall pieces, to ensure the stability of the existing scaffolding and shelves workers safety. (6) Scaffolding in free height above the point where the top wall or must be less than 6m. When the job-storey wall pieces under its 2-step or more than 4m, on which there is no wall pieces, you must use steel structural columns and the upper end of the scaffold temporary Rachel. f, laying scaffold boards (1) scaffold boards should be paved, paved stable, away from the wall 120 ~ 150mm, operating level to take 150mm. Butt tile, corners with a diameter of 1.2mm galvanized steel wire firmly fixed in the longitudinal horizontal bar. (2) In the corner of the mouth of the chute platform scaffold boards should be securely connected with the horizontal bar to prevent slippage. (3) from the top layer of the scaffold boards down the job count, should be full every 12m layer of scaffold boards. g, dismantling scaffolding (1) shall be divided rack demolition work area, surrounded by fences or warning signs erected, the ground has a special command, prohibited non-operating personnel from entering. (2) Before scaffolding removed should be examined whether the debris and obstacles on the ground cleaned. (3) the removal of the workers in high places, must wear a helmet, wear seat belts, tie leggings, wear soft-soled shoes. (4) To dismantle the unity of command, up and down Hu should, motor coordination, when associated with another person untie the knot, you should first inform the other party, may fall. (5) removal of scaffolding follow "from top to bottom, the first ride demolition, demolition after take first" principle, ie reverse and erection work program dismantled. That is the first demolition of railings, scaffold boards, scissors, bracing, after the demolition of a small bar, a large bar, pole, etc., according to the principles of a clear step sequentially, and down at the same time be prohibited demolition. (6) the demolition of the pole, the pole should be embraced and then open the last two buckle, dismantling a large bar, bracing, scissors, should be removed in the middle button, then hold the middle, then the solution ends buckle . (7) The wall pieces should progress step by step with the demolition demolition, demolition bracing ago, should set up a temporary support, then split bracing. Wall pieces must be dismantled in order to release all of its detachable lever located on both demolished after. (8) during the removal process, who have releasable connecting rod parts should be dismantled carried away, to avoid misuse and misuse by supporting rods have loose connections. Remove the lever fittings shall be transported in a safe manner and hanging out, the non-down throw. In the removal process, good cooperation and coordination of work, a single person is prohibited hazardous heavy demolition jobs pole pieces. (9) Before demolition should be reserved for large rack ramps, loading platforms, channel jumping and other boats, first reinforcement, so that after the removal to ensure their integrity, security and stability. If there is foreign line (10) Remove the vicinity, to take quarantine measures. Non-contact wire frame bar. (11) Remove the material, the application of rope tethered, use a pulley slowly down transport, non-throwing, transported to the surface of the material should be designated locations, with the split with the transport, sorting stacking, clear day, the day of the demolition, the removed fasteners or wire to focus on recycling. (12) Dismantling process can not change horses in midstream, as time must be replaced, before leaving should explain clearly after dismantling. h, scaffolding safety measures (1) to participate in the construction workers erection and dismantling of scaffolding must be certified for the scaffolding work in construction workers to regular safety education and safety before construction of its technical disclosure. (2) Scaffolding must be acceptance by scaffolding acceptance criteria after the erection of the completion of the organization concerned, and may use all completed later after passing inspection procedures. (3) Before using scaffolding and every day after work must be performed by someone more scaffolding for routine maintenance and inspection intervals before and after a certain period of time and bad weather for inspection, inspection and maintenance of all to make a written record. (4) Do not overload the scaffolding material heap charge; the absolute prohibition of vibration equipment and scaffolding linkages; prohibit any support and scaffolding are linked. (5) the erection and dismantling of scaffolding under special climatic conditions, there must be effective and reliable safety assurance measures, rain and fog days scaffolding must be anti-slip. (6) The removal of the scaffolding should follow the removal process and construction programs. (7) The removal of staff positions after arrival, the first inspection, reinforcement loose parts, remove the material layer to stay within walking, objects and garbage blocks. All clean-up material should be safely transported to the ground, throwing prohibited altitude. i, scaffolding Fire-fighting measures (1) mine outside scaffold using a separate building at the corner of buried electrical grounding, the grounding resistance of less than 4. When applied electricity cable may not be directly embedded in the scaffold, as must tie in scaffolding, insulation should be reliable. (2) fire prevention policy, clean combustible building materials and scaffolding, setting fire extinguishers on every floor and the Master of the ramp at the use of fire to be approved, and have someone to care. Smoking is prohibited on the scaffolding, to prevent the fire source.
