1. The Invention |

Title Adjustable
level, high strength street inlet The problem the inventor(s) wanted to solve The protruding objects of
the road surface are damaging the wheels (tyres, axle bearings, etc.) of the
vehicles. The inventor intended to prevent such a damaging problem creating a
high strength street inlet construction the level of which is adjustable with
respect to the road surface and this way it does not cause bumpiness and does
not cause damages to the vehicle wheels. Description. The object of the invention
is a high strength street inlet where the level of the manhole head and its
frame can be adjusted to be flush mounted with respect to the crown surface
of the road. It is simple and easy to manufacture. Presentation. The invention essence is
that the manhole head frame is quadrilateral shape and in each one of its
four corners there are adjustable lifting screws. These lifting screws can be
adjusted from the top surface of the manhole head using a special box wrench
to adjust the manhole head level with respect to the road crown. The manhole
head frame is made of cast iron while the lifting screws are made of steel.
The lifting mechanism is protected by plastic shell during the imbedding in
concrete. The manhole head frame has a conical skirt that prevents the four
lifting screws to hold the load and transfer it at the shaft wall, instead, the frame transfers the load to the upper,
concrete layer of the road crown. The level adjustment of these kind of street inlets can be done until the last phase of
the concrete and asphalt laying. This way a high precision level adjustment
can be achieved in the order of one millimetre. Application This manhole head
construction can first of all be used on the public roads to cover the
manholes of the sewage and other industrial conduits. Advantages The manhole head represents
a solution that facilitates both the rapid installation and level adjustment.
It does not bear up at an edge but a conical surface and, this way, the
damage of the concrete structure can not be expected due to the load and no
frequent road repair is required. Being monoblock
design it can be made together with the foundation that facilitates the level
adjustment in an arbitrary place and time according to the road crown site
conditions. The heavy axle load trucks do not produce bumping when they pass
over the invented manhole head construction since it does not tilt. Its use
results in a long useful lifetime, since no temporal building required and
this way energy can be spared. Stage of development. Model, prototype and final
products have already been produced. Documentation available: Technical drawings,
leaflets, video and CD are available |
