PRECAST
CEMENT CONCRETE
DRAIN
SECTIONS
Introduction
It
is a Unique concept of making Precast Drain
Section with Reinforcement by Hydraulic
Vibro Pressed making machine as per IS 2185
part I of Grade ‘D’ . Precast drain section
are accurately designed and machined moulded
with uniform shape & size & clean
Finish They have extra strength as they
are manufactured under stringent quality
control measures by using concrete of high
grade M-150 to 300 .They are made upto 150
mm thick and 1500 mm in depth .Due to longer
life span & maintenance free they have
far less replacement / maintenance cost
as compared to conventional drain section.
Curing
Technique
The
fresh blocks after initial setting are covered
by jute rolls /and are continuously moist
by sprinkling water in order to retain the
initial moisture and to reduce the heat
of hydration for a period of minimum 10days
from the casting.
Testing
Blocks
after they are fully cured are tested in
our site laboratory for the crushing strength
of the core of blocks as per the IS 2185
Part I grade "D" by the help of
a compression testing machine .
Once they are tested and passed as required
are ready for dispatch to the concerned
for laying at sites .
Measurement
Measurement
of
drain
section is taken as under
Centre
line of thickness of block in Mt. x length
of section =Sqm. Area.
Nominal Length
of one block without reinforcement
shall
be 400mm ± 5mm .Nominal length of one block
with reinforcement shall be 500mm
±
10mm .
Where to
Use
These
sections can be used as City Drains , Strom
Water Drain, Cunnet, Water Courses ,Minors.
How
To Use
Precast
drain can be installed with simple laying
techniques .The Blocks are laid on directly
compacted earth or on the base of 150mm
quarry rubbish ,if needed.
Types
and Sizes
Precast
Drain Sections are available in fifteen
different shapes and
sizes
(with and without reinforcement) and can
also be made as per your size and specification
.
