MNUFACTURING TECHNIQUE OF ARC MANHOLE
ARC-GRP manhole are produce on Helical winding machine , GRP manhole are manufaturd from
polyester resin with high class glass fiber reinforced as per the specification ASTM D-3753
HELICAL FILAMENT WINDING MACHINE
Pipes are manufactured using the Filament Winding process on fully automatic controlled machines
(CAM), by adjusting the relative speed of mandrel rotation and glass distribution head movement,
helical reinforced layer with different angles can be wound. The inside diameter of the finished pipe
is defined by the mandrel outside diameter and the designed wall thickness is achieved by repeated
passes. Therefore the outside diameter of pipe (OD) is determined by the wall thickness.
ARC MANHOLE WALL STRUCTURE
GRP manhole wa ll consist of three layers perfectly adherent one to the other and each having different
characteristic and properties in re lation to their function.
LINER
Liner or chemically resistant layer is the internal layer of the manhole; it is in direct contact with the
conveyed fluid. This layer has the function to guarantee the resistance to the chemical corrosion and
the impermeability of the whole manhole chamber. Liner has the internal surface namely the one in
contact with the conveyed fluid, particularly smooth. This characteristic of smoothness reduces to
minimum the fluid head losses and pumping heads and opposes to the growth of mineral deposits
and algae. Liner is made of two monolithic sub-layers (1) Inner, in direct contact with the fluid, is
reinforced with glass veil “C” 30 g/m2, with ratio resin content in a range 80% - 90%by weight (2)
Outer, reinforced with plies of glass mat “E” of 450 g/m2, with a resin content in a range of 60% -
70% by weight.

MECHANICAL RESISTANT LAYER
Glass reinforced layers guarantee the mechanical resistance of the whole pipe against stresses due to internal
and/or external pressure, external load due to handling and installation, and thermal loads. The layer is
obtained by applying on the previous pa rtly curved liner, continuous roving of glass wetted with resin, under
controlled tensioning. This layer can conta in aggregates (inert granula r materia l such as silica) in order to
increase the stiffness of the whole pipe. Thickness of mechanical resis tant layer depends on the design
condition.
TOP COA T
Top coat or Gel coa t is the outer layer of the pipe which consists of pure resin added with UV protectors to
protect the pipe from sun exposure. In case of severe exposure conditions, i.e. aggressive soils or very
corrosive environment, the gel coat can be reinforcement with a surfacing veil or added with fillers or
pigments...

MANHOLE TESTING
ARC has conducted a qualifying manhole test according to ASTM 3753 as explained below.
ARC GRP MANHOLE TEST
A loading test was conducted on a 1200 x 600 mm concentric manhole manufactured in order to
demonstrate that ARC standard GRP manhole could resist the loading criteria according to ASTM D
3573.
The test followed the guide lines of ASTM D3753 “Standard Specification for GRP Manholes” and
proved that ARC Standard Concentric Manhole was found to be capable of resisting the loading
requirements as stipulated in this Standard.
The goal of this test is to prove that the manhole will not crack or suffer other damage when loaded
to 40000 lbf (177929 N) approx 18.2 tons and will not be deflected vertically downwards more than
0.25 inch(6.35mm) when loaded to 24000 lbf (106757 N) approx 10.9 tons.

PROCEDUR
The specified load is applied eccentrically on (150*150*12.7 mm) steel plate resting on the manhole
cover. The centre of the steel plate is located such that it is within 102 mm from the edge cover. The
manhole is located in increments of 2 tons till the desired load is reached; deflections are not at each
point.

GRP MANHOLE ADVANTAGES
ARC GRP manholes offer benefits in four major areas compared to tradi tional concrete
manholes and vaults. These advantages are in the areas of serviceability, durability,
envi ronmental sensitivi ty, and economy
SERVICEABILITY
Manholes are often entered frequently. These entries are necessary to inspect water flow,
control water flow valves, maintain and calibrate electronic sensor packages that are reading
the water depth in the flume if existing. In all but the shallowest manholes, this is a confined
space entry. To make a safe confined space entry, the technician is burdened by the bulky safety
equipment including the safety harness. GRP manholes have more head room than traditional
pre-cast concrete manholes because the shaft diameter is maintained throughout the depth of
the shaft. Pre-cast concrete ring type manholes are generally constructed with a 30-inch neck
that only bells out to four or five feet near the bottom. This configuration makes i t difficul t to
crouch down and take depth readings or work on a sensor. In addition to that, the walls of the
ARC GRP manholes are smoother than concrete and less apt to build up a coating of slime. The
larger opening and smooth walls also allow for better lighting conditions. All of which adds up to
a better working environment for the technician. From the client’s perspective, the client will
save money on such a product that can be installed easily and quickly.

DURABILITY
ARC GRP manholes resist degradation from
groundwater, sewage, and corrosive chemicals
far more effectively than concrete. While the
ul timate life span of a given GRP manhole
would be dependent on the
Types of chemicals present in either the
groundwater or the waste-stream, it is possible
to s tate that GRP will far outlast traditional
degradable concrete in every application. In
certain industrial applications and at landfill
monitoring sites, the durability of GRP may be
the most important cri teria. GRP manholes are
extremely resistant to chemical corrosion. The
contractor’s main concern with respect to
durability is whether the product is sufficiently
rugged enough to withstand damage during
installation. In this respect, the durability of
the GRP manhole is more than sufficient.
ENVIRONMENTAL SENSITIVITY
Since ground water contamination is a major
concern, GRP manholes make sure that the
wastewater being conveyed is isolated from
the environment. This advantage is paired
with the durability of GRP manholes. An all
GRP manhole vastly reduces the possibility of
ground water intrusion. Ground water
resources are therefore protected, and
expensive manhole rehabilitation to prevent
ground water contamination can often be
avoided indefinitely.

ECONOMY
On a fi rst cost basis, GRP manholes with very large flumes are less expensive than large concrete
vaults . This is because by using GRP we are able to extend the up and downstream portions of
the flume that do not require service access outside the manhole. The laminated GRP cover
permits these parts of the flume to be di rectly buried in the soil. Using concrete construction, an
expensive vault must be built that is large enough to cover all parts of the flume. Concrete
construction has a lower fi rst cost for small flumes that can be contained in a
Four, five, or six foot diameter circle. If the greater durability of fibreglass is considered, the
lifetime cost of fibreglass may be far lower than concrete due to the high cost of rehabilitating
or replacing a concrete s tructure. At industrial sites or in cases where the municipality is
predisposed to consider the long-term costs of maintaining manholes, i t is found that fibreglass
is highly beneficial. Often at a firs t glance, the cost picture is misleading. GRP manholes provide
hidden cost benefits in the areas of installation and reduced likely-hood of spoiling the flume
during installation. Often the apparent savings offered by a cheaper pre-cast concrete manhole
evaporate when the true cost of installing a complete metering station is factored in. Not to
forget that one-piece design GRP manholes are relatively light - weight compared to concrete
manholes which eliminates the need for heavy equipment on the job si te and installation is
therefore less time consuming.
