| (54) | Reinforced sectional gutter |
| (57) The invention describes a reinforced sectional and modular gutter (C), with improved
male (5) and female (6) joints at its extremities and with improved male joints (5)
in the intermediate zones (G) for the formation of submultiples of gutter always with
male and female joints at the extremities. It is also described the formation externally
provided with ribs of a modular gutter, which improves its rigidity, its resistance
to mechanical stresses and which improves the anchoring of the poured cement or concrete
inside which it will be embedded. Each modular gutter is provided at one end with
joints (15, 115) for pipes for the inlet o discharge of water, which are in origin
closed but can be opened easily. It is also described an improved head element (S)
for the shutter closure of the extremities of the gutter or for the closure of the
not utilised parts of a cross joint (X) which can be associated with sectional and
modular gutters in order to increase their flexibility of employment in the formation
of linear drainage channels or with interconnection of the L-, T- or cross- type.
