【正文】 m elevation of the box after preloading to readjust the Elevation of the bottom. 2, template fabrication and installation templates to create and install (1) the end of the template used chunk of plywood, shop at the top of longitudinal frame of wood, the wood and plywood with a nail fixed, transfer mode, plete the unloading mode with adjustable backwater. (2) outside the template within 5cm Heavy plate after polishing paste δ = 12mm ~ 15mm bamboo, vertical spacing of 90cm set square wooden support rib, lateral distance of 50cm set channel support outside the direct distribution of the beam mode, when assembled within the outer after the template on the pull with the screw on the pullΦ18. (3) The bination of steel used within the model, the local size change using wooden mold, the template is mainly used for pulling the fastening screw, and connected with the used in the steel box girder formwork support, direct support in the bottom bracket. (4) Plug the template due to perforation of reinforced and prestressed in the template using plywood digging holes, dug by cutting section size, perforation of reinforced and prestressed pipe must be precisely positioning the cutting. Template Installation Notes (1) Production of a template before the first familiar with the parts drawing and template processing maps, engineering structure or ponent to verify the detail size, plex structure should be like by zooming in order to proper preparation, processing and map production of the approved template, inspected and acceptedbefore use. (2) template to seal the joints, where the gap, the use of 107 plastic plug close to plasma leakage. (3) the arrangement of the bolt hole should be vertical and horizontal symmetry, a certain degree of regularity and decoration in good condition. (4) connecting seam tape adhesive template, templates, bent pitched plete acceptance of the invitation after the Commissioner of the next process. 3, steel processing and installation First test of reinforcing bars, meet the requirements for steel processing, welding the reinforced using doublesided welding, welding length of not less than 5d, smaller internal forces at the joint set, and staggered layout, welding joint area of not more than 50%.Based on the design drawings, will be reinforced in the next cutting plant material transported to the scene after the banding. Roof, floor, there are a large number of embedded web bellows, in order not to damage the bellows, welded bellows embedded all before, try not to weld pipe after installation, when the general location of steel bars and corrugated pipe into conflict whenMobile reinforcing bars, the appropriate and accurate positioning steel mesh installed to ensure accurate location of pipelines. Steel banding ago by surveyors retest the template location and elevation plane, which includes elevation calculated by the deflection of the hanger of the camber set, correct the rear of the steel banding. To enable accurate data protection layer, protective layer pads are not crushed, by setting plastic box pad pad construction. 4, bellows processing installation Position as shown in the drawings according to design layout bellows, and with the positioning ribs fixed, placed after the pipe must be smooth, nonchine. Length of all pipe joints 5d prevail, the use of corrugated pipe larger size socket to tighten the symmetry, and good joints wrapped with adhesive tape to prevent concrete slurry mixed with fine, when the pipeline location and conflict with nonprestressed reinforcement to takepipelinebased principles, the appropriate location of the mobile reinforcement to ensure that the correct pipe. Bellows the end of the embedded anchor plate should be perpendicular to the channel center line, and does not produce displacement during the concrete is installed, it will cover its end to prevent water or other debris to enter. Construction workers, mechanics, pipe vibrator can not crash. Before pouring concrete pipe carefully examined whether there
