TYPICAL "TEE"-BASE MANHOLE TYPICAL MANHOLE SECTION 
180º TEE BASE CONFIGURATION 
TYPICAL "TEE"-BASE DETAILS LONGITUDINAL SECTION 
TRANSVERSE SECTION 
Typical 'Tee'-Base Section 'Tee'-Base sections are normally used to provide access to large diameter pipe lines. Generally, slopes are minimal and they have only an inlet and outlet of the same size although smaller inlets may be incorporated in the structure. They are available in sizes ranging from 600mm to 2400mm diameter concrete pipe. Spigots for 1050mm or 1200mm diameter shafting are cast integral with the base section. Due to the diverse applications in which they may be utilized, please contact SHAW PIPE for specific information pertaining to your project.
