Modular manhole channel liners

Abstract

A manhole channel liner includes a plurality of channel liner sections. The manhole channel liner routes the flow between at least two pipes that enter a wall of a manhole. Each channel liner section includes a flow channel formed in a top thereof. The plurality of channel liner sections are laid in the manhole to connect the flow from at least one inlet pipe extending through a wall of the manhole to at least one outlet pipe. The manhole channel liner is preferably held in place with a wet pour material, after thereof have been aligned. The plurality of channel liner sections may be retained in place with at least one alignment key.

1 . A method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole, comprising the steps of: 
 providing a plurality of channel liner sections, each one of said plurality of channel liner sections having a flow channel formed in a top thereof;    aligning said plurality of channel liner sections to provide flow from the at least one inlet to the at least one outlet; and    placing a wet pour material on both sides of said plurality of channel liner sections.    
   
   
       2 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 1 , further comprising the step of: 
 connecting said plurality of channel liner sections with at least one alignment key.    
   
   
       3 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 1 , further comprising the step of: 
 forming at least one key slot in each one of said plurality of channel liner sections to receive said at least one alignment key.    
   
   
       4 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 1 , further comprising the step of: 
 laying a support layer under said plurality of channel liner sections.    
   
   
       5 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 1 , further comprising the step of: 
 mitering at least one end of at least one of said plurality of channel liner sections.    
   
   
       6 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 1 , further comprising the step of: 
 forming a pair of slopped surfaces on a top of each one of said plurality of channel liner sections.    
   
   
       7 . A method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole, comprising the steps of: 
 providing a plurality of channel liner sections, each one of said plurality of channel liner sections having a flow channel formed in a top thereof;    aligning said plurality of channel liner sections to provide flow from the at least one inlet to the at least one outlet;    connecting said plurality of channel liner sections with at least one alignment key; and    placing a wet pour material on both sides of said plurality of channel liner sections.    
   
   
       8 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 7 , further comprising the step of: 
 forming at least one key slot in each one of said plurality of channel liner sections to receive said at least one alignment key.    
   
   
       9 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 8 , further comprising the step of: 
 laying a support layer under said plurality of channel liner sections.    
   
   
       10 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 8 , further comprising the step of: 
 mitering at least one end of at least one of said plurality of channel liner sections.    
   
   
       11 . The method of routing flow from at least one inlet in a wall of a manhole to at least one outlet in the wall of the manhole of  claim 8 , further comprising the step of: 
 forming a pair of slopped surfaces on a top of each one of said plurality of channel liner sections.    
   
   
       12 . A method of routing flow inside a manhole to at least one outlet in the wall of the manhole, comprising the steps of: 
 providing a plurality of channel liner sections, each one of said plurality of channel liner sections having a flow channel formed in a top thereof;    aligning said plurality of channel liner sections to provide flow across a bottom of the manhole to the at least one outlet; and    placing a wet pour material on both sides of said plurality of channel liner sections.    
   
   
       13 . The method of routing flow inside a manhole to at least one outlet in the wall of the manhole of  claim 12 , further comprising the step of: 
 connecting said plurality of channel liner sections with at least one alignment key.    
   
   
       14 . The method of routing flow inside a manhole to at least one outlet in the wall of the manhole of  claim 13 , further comprising the step of: 
 forming at least one key slot in each one of said plurality of channel liner sections to receive said at least one alignment key.    
   
   
       15 . The method of routing flow inside a manhole to at least one outlet in the wall of the manhole of  claim 12 , further comprising the step of: 
 laying a support layer under said plurality of channel liner sections.    
   
   
       16 . The method of routing flow inside a manhole to at least one outlet in the wall of the manhole of  claim 12 , further comprising the step of: 
 forming a pair of slopped surfaces on a top of each one of said plurality of channel liner sections.
