METHOD STATEMENT FOR INSTALLATION OF GRP PIPES FOR STORM WATER

TOOLS / EQUIPMENT

Material Handling & Storage
On receipt of GRP pipes & fittings , the materials shall be handled & stored in line with the following procedure:

  1. Pipes will be stacked on a flat surface free from sharp projections, stones or other objects likely to cause point loading or pipe deformation.
  2. The storage area shall be kept in proper level, so that the stacked pipes may be uniformly supported throughout their length.
  3. Pipes will not be dropped on hard surfaces and will not be dragged along the ground. Wherever possible the loading and unloading of pipes will be carried out manually by hand.
  4. If mechanical lifting equipment is used, ensure no metallic slings, hooks or chains will be used in direct contact with the pipe. Rope or nylon belt sling will be preferred which will not damage or cut the pipe surface.
  5. When socket pipes are stacked, the sockets will be placed at alternative ends of the stack with the socket protruding so that pipes are evenly supported along their entire length.
  6. Pipe of different sizes or wall thickness will be stored separately or where this is not possible, those with larger diameters and / or thicker walls will be placed at the bottom of the stack.
  7. The stacks will be protected from direct sunlight by covering with tarpaulin sheets.
  8. All the pipe fittings will stored in the boxes as supplied by the fittings manufacturer.
  9. When storing the pipe on ground near the trench .it is necessary that the soil must be levelled and not to contain any hard bodies exceeding 40 mm that could damage thepipe. For long storage,pipe should be placed on supports of 10 Cm.wide at every 2.5 Mts. distance with side blocks to prevent the pipe from rolling.
  10. RUBBER RING STORAGE
    Rubber rings must be stored in cool and dark place. Never let the rubber ring outside in the sun. Avoid contact of rings with grease or oil.
