when laid to the required levels and gradients shall be no the bottom fully supported along the

entire length of the pipe. The trench shall be deepened and widened locally to receive the sockets

and to permit the joint to be made and inspected.

Before excavation is started rails shall be erected at convenient places and at all changes

of direction and gradients at a definite and as far as practicable uniform height above the

proposed invert level of the pipes the center lime being clearly marked on each horizontal rail.

The depth of excavation and level of the pipe invert shall be checked by means of benching road

of appropriate lengths.

Disposal of the Excavated Stuff :

The excavated stuff of the selected type shall be used for filling the trenches and plinth or

leveling the ground in layers including ramming and watering etc. complete. The Contractor shall

remove the balance of the excavated from the site of work to a place as directed within a lead

unto 50mm and for all lift.

Filing of Trenches:

As soon as the work in foundation has been completed and measured the sides of

foundation shall be cleared of all dedans brick bats mortar dropping etc. and filled with earth in

layers not exceeding 15 cm 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 trenches and plinths. Under no circumstances black cotton soil shall be used for filling

FILLING MATERIALS:

Filling materials may be either excavated stuff of selected materials brought from outside.

Excavated stuff or selected earth to be used shall be cleared of all rubbish large size stones brick

bats etc. complete and big clods shall be broken down to a size of 50 mm or less. The selected soil

and or murmur or any other materials shall be got approved before filling.

Refilling shall be done in a systematic manner by the contractor before refilling starts, the

contractor shall got checked the trenches ready for refilling.

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 danger to pipe line for foundation footing plinth well etc. already laid or built up.

If watering is not done by contractor with its own arrange meant watering charges at 20%

of this item rate shall be deducted from the bill against this item.

The rubber ring shall be stored in a cool dark dry and dust free environment The storage

shall not be exposed to direct sunlight or any heat radiating appliance. The rings shall not be

allowed to come in contact with any fuels and shall be stored free of tension.

Rubber rings shall be clearly labeled in bundles to indicate the type of ring. The size of

pipes for which they are to be used the manufacturer’s name or trademark and the month and

the year of manufacture.

The rings shall comply with IS 5382 regarding their material finish tolerance in dimension

and physical requirement.

The rubber rings shall be such that they shall not show any signs of deterioration for any

reason during the contract period plus the defects liability period, Entire expenses associated

with correcting defects in this regard including replacement of rubber rings shall be fully borne by

the contractor.

In jointing cast iron spigot and socket pipes and fitting with tycoon flexible joints the

contractor shall take into account the manufacturer’s recommendations as to the methods and

equipment to be used in assembling the joints. In particular the contractor shall ensure that the

spigot end of the pipe to be jointed is smooth and has been properly chamfered that the rubber

ring as per IS 5382 is correctly positioned in the socket and that the two pipes are accurately in

line, before the joint is made. The rubber rings and any recommended lubricant shall be obtained

only through the pipe supplier or as directed by the Engineer.

LEAD CALCULATING JOINTS

The jointing shall be done with molten lead and spun yam. Pin lead shall be of uniform

quality clean and free from foreign materials. It shall be of uniform softness capable of being

easily caulked or driven. It shall conform to IS: 782 Spun yarn shall be of clean hemp and of good

quality. It shall conform to IS: 6587 Its quantity shall be as follows.

Quantities of spun Yarn for Different Sizes of Pipes

(Materials for single collar joints)

Nominal Internal Spun Yarn Mass

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

QUANTITIES OF LEAD YARN FOR DIFFERENT SIZES OF PIPES

Normal Size Lead/ Joint Depth of

Pipe mm 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 the pipe.

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
