each layer shall be adequately watered rammed well and consolidated before the succeeding layer is laid.

The earth shall be rammed with iron rammers where feasible and with the butt ends in layer of crowbars

where rammer cannot be used. The plinth shall be similarly filled with earth in layers not exceeding 15 cm

adequately watered and consolidated by ramming with iron or wooden rammers. When filling reaches

finished level the surface shall be flooded with water for at least 24 hours and allowed to dry and then

rammed and consolidated. The finished level of filing shall be kept to shape and gradient intended to

receive any floor finish. The excavated stuff of the selected type only shall be allowed to be used for filling

The space between foundation masonry concrete pipe line and the sides of excavation and/or bottom of

found at ion shall be refilled to the original surface or up to plinth level with earth or selected materials in

layers of 15 cm to 20 cm each well watered and rammed.

Each layer shall be watered and compacted with heavy rammer before the upper layer is laid till the final

level is reached to form a thoroughly compacted base.

Refilling on top of pipe shall be carried out carefully with selected soft stuff out of the excavated stuff. The

refilling shall be raised about 5 cams. For subsequent settlements.

The contractor shall be responsible for any settlement during passage of time of

during monsoon and the same shall be refilled with stuff brought from the out

side if necessary.

The process of refilling brunches in plinth watering ramming shall be carried out in such a way as not to

Note: Under special circumstances the Engineer-in-charge may decide the quantities of spun yarn

depending upon the site conditions. The quantity of different diameters of C.L. pipes and fittings

shall be as follows:

QUANTITIES OF LEAD YARN FOR DIFFERENT SIZES OF PIPES

Normal Size of Lead/ Joint Depth of lead

Pipe mm Kg Joint mm

Note: The quantities of lead given are provisional and a variation of 20 percent is permissible either way.

Lead shall be heated in a melting pot kept in easy reach of the joint to be poured so that the molten metal

will not be chilled in being carried from the melting pot to the joint and shall be brought to a proper

temperature so that when stirred it will show a rapid change of color. Before pouring all scum shall

be removed. Each joint shall be made with one continuous pour filling of the entire joint space with

solid lead. Spongy or imperfectly filled joints shall be bunt out and repaired.

The joint runner shall fit snugly against the face of the socket and the outside of the pipe shall be dammed with

clay to from a pouring lip to provide for filling the joint flush with the face and to the top of the socket.

The jointed is done by first caulking in spun yam, then filling the remainder of the joint space by running in

molten lead, taking care that no dross enters the joint and then thoroughly caulking the lead. The spun

yam shall be used to center the spigot in the socket and to prevent the flow of molten lead into the bore of

After the lead has been run into the joint the lead shall be thoroughly caulked. Caulking of joints shall be done

after a convenient length of the pipes has been laid and leaded. The leading ring shall first be removed and

any lead outside the socket shall be removed with a flat chisel and then joint caulked removed with a flat

chisel and then the joint caulked around three times with caulking tools of increasing thickness and

hammer of 2 kg. Weight Lead run joints shall be preferably finished 3 mm behind the socket face. The

joints shall not be covered till the pipe line has been tested under specified hydrostatic test pressure,

though the rest of the pipe line should be covered up to prevent expansion and contraction due to

variation in temperature.

Filling available excavated earth (excluding rock) in trenches plinth sides of foundation etc. in layers not

exceeding 20 cams. In depth consolidating each deposited layer by ramming and watering.

The refilling will generally refer to refilling of pipe line trenches, foundation trenches up to plinth level or

ground level with excavated stuff selected soil brought from outside.

Clearing or Trenches or Ground:

The excavated trenches for foundation or ground over which filling is to be done shall be cleared off all

grass loose stones rubbish of all kinds brick bats as well as tress roots etc.

They shall be well watered before stuff is laid.
