Abstract
Flumes for manhole inverts are described and formed of integrally molded segments which interfit with each other so as to connect inlets to an outlet of a manhole independent of the shape and size of the manhole. The flumes are made in a set and in one set the flumes are formed of a pipe segment which either is integrally connected to an open channel segment or connected thereto with suitable fasteners and with the overall length of the flume being substantially less than the distance between the inlet and an outlet of the manhole. Another set of flumes has only open channel segments which are generally substantially smaller in length than the flumes which have both a pipe and an open channel segment. The open channel segments are provided with end flanges to enable their connection to similarly shaped channel segments to form inverts.
Claims19
A flume for an invert for a manhole having a base along which a flume path connects an inlet at the manhole base to an outlet at the manhole base, comprising:
- a first flume having a pipe segment and an open channel segment in fluid communication with said pipe segment;
- said pipe segment and said open channel segment having an overall length that is substantially smaller than the distance between said inlet and outlet as measured along said flume path;
- a second flume having an open channel segment and a pipe segment in fluid flow communication with said latter open channel segment, and with the overall length of said second flume being substantially less than said distance between said inlet and outlet ports along said flume path;
- the open channel segment of the second flume having a like cross-segment as said channel segment of the first flume;
- said second flume having a complementary cross-sectional shape with respect to said first flume so as to form a continuous invert between said inlet and outlet at the base of said manhole when the channel segments of said first and second flumes are in abutment with each other.
A flume for an invert for a manhole having a base along which a flume path connects an inlet at the manhole base to an outlet at the manhole base, comprising:
- a first integral flume having a pipe segment and an open channel segment in fluid communication with said pipe segment;
- said pipe segment and said channel segment having an overall length that is substantially smaller than the distance between said inlet and outlet as measured along said flume path;
- a second integral flume having an open channel segment and a pipe segment in fluid flow communication with said latter open channel segment, and with the overall length of said second flume being substantially less than said distance between said inlet and outlet ports along said flume path;
- the open channel segment of the second flume having a like cross-section as said open channel segment of the first flume;
- said second flume having an open channel segment which has a cross-section that is complementary shaped with respect to the open channel segment of said first flume so as to enable the formation of a continuous invert between said inlet and outlet at the base of said manhole when the open channel segments of said first and second flumes are in abutment with each other.
Invert forming flumes for a manhole having a base along which a flume path connects an inlet to an outlet at the manhole base, comprising:
- a first set of flumes having integrally molded pipe segments and open channel segments, with the open channel segments having like cross-sections;
- selected flumes having straight open channel segments and selected flumes having curved open channel segments so as to impart a change of direction relative to the integrally connected pipe segments;
- said flumes being interconnectable at ends of said open channel segments to form a multiple flume part connection between the inlet and outlet of the manhole.
A flume for an invert for a manhole having a base along which a flume path connects an inlet at the manhole base to an outlet at the manhole base, comprising:
- a first pipe segment and a first open channel segment sized for fluid communication with said first pipe segment;
- said first pipe segment and said first open channel segment having an overall combined length that is substantially smaller than the distance between said inlet and outlet as measured along said flume path;
- a second pipe segment sized for fluid flow communication with said first open channel segment, and with the overall combined length of said first open channel segment and said second pipe segment being substantially less than said distance between said inlet and outlet ports along said flume path;
- the first open channel and pipe segments having like cross-sections so as to form a continuous invert between said inlet and outlet at the base of said manhole when the first open channel and pipe segments are in abutment with each other.
A flume for an invert for a manhole having a base along which a flume path connects an inlet at the manhole base to an outlet at the manhole base, comprising:
- a first open channel segment and a second open channel segment sized for fluid communication with said first open channel segment;
- each of said open channel segments having an overall length that is smaller than the distance between said inlet and outlet as measured along said flume path;
- said open channel segments having end located flanges to enable their abutment connection to each other, with said first and second open channel segments having like cross-sections so as to form a continuous invert between said inlet and outlet at the base of said manhole when the first and second open channel segments are in abutment with each other.
