Kneel for the construction plan and safety special plan of the municipal landscape bridge and the st

I have. Do you have an email address?

The construction process is the special hoisting plan for the steel structure, which is necessary to have such as Qin Xunguo supervision requirements, but also to prepare a special plan for temporary electricity, the special plan for safety is a collective term, according to the characteristics of the project, mainly including high-altitude work, welding work, mechanical work, hot work and so on!

Construction of the steel structure of the new pedestrian bridge.

1) Machinery and equipment.

Semi-automatic cutting machine, hand-lifted bar drill, grinding machine, angle grinding machine, 25t wheeled crane, truck, flatbed trailer, electric welding, gas welding equipment, etc.

2) Main implements.

Wedges, pulleys, inverted chains, jacks, arc gouging, wire ropes, snap rings, rope clamps, feeler gauges, steel tape measures, levels, tower rulers, etc.

3) Production process.

Raw materials are corrected, lofting, blanking (shearing and gas cutting) in the factory according to the design requirements, parts are straightened and slag removed, planed, drilled, semi-finished products are classified and stacked, groove rust is cleaned, steel plate is connected, welded, ultrasonic flaw detection, leveling, weld inspection, and geometric dimensions are checked. After meeting the design and specification requirements, the semi-finished products will be transported to the site.

4) The following points should be paid attention to when processing at the manufacturer:

End milling. The design requires planing, cutting, and grinding the local unevenness with an angle grinder.

Drill. In particular, group holes and row holes require accurate hole spacing, and drilling machines can be used, and steel plate stacking drilling methods can be used. The burr should be removed after drilling.

Planing edges. Welding groove with planing machine planing, planing groove. The groove that can not be planed by the planer and the planer can be cut out of the slope with a semi-automatic cutting machine, and then grinded with a grinding machine, and the groove angle must be correct.

5) After the materials enter the site, they must be placed in batches and classification, and should be neatly stacked and covered with canvas or adhesive tape when they cannot be used immediately. Sleepers must be laid to keep them dry, and the material must not touch the ground.

6) Hoisting of semi-finished steel products. 25t rubber tyred crane is adopted. Before hoisting, the elastic line should be on the template according to the design requirements, and a single hoisting should be used when hoisting, and the lifting point should be tied at four points, and the binding point should be padded with soft material to prevent damage to the steel components.

When lifting, the component is first hoisted from the ground about 50cm, and then the hook is slowly lifted, the component is hoisted above the overpass, and then the member is rotated with a slip rope to align it with the installation site.

Ask like this, is not to get the answer, you say with a helicopter is OK, hehe, this is to have a special construction plan, find the technical person in charge to do, the specific situation is uncertain, no one can determine the construction plan, and, is the overall demolition or split, so the construction plan construction process method The selection of machinery is not the same, the following is open to traffic and people are not, how long can it be closed, etc., are uncertain, can not be determined.

A full house of professors, dismantled little by little, this is the cheapest solution.

Find the drawings and then talk about it, gradually decompose the structure according to the original drawings, and don't consider lifting the whole of 100 tons.

Can the crane be far away? Two meters of soil cover should be within a safe range, right?
