CONCRETE MANHOLES

1 MANHOLESSHAW PIPE PRODUCT GUIDE AND TECHNICAL REFERENCE MANUALCONCRETE PIPESECTION 3 SHAW PIPE produces circular, precast , concretemanholes in diameters 1050mm through 3000mm . precast , CONCRETE MANHOLES are most frequently usedfor pipeline and sewer entry and are easy to installand low in PIPE follows various standards andspecifications in the production of precast , concretemanhole units. These standards and specificationsare listed in the "Specifications" precast , CONCRETE manhole configurationsconsist of a precast base or tee base, intermediaterings, flat top cover or eccentric cone top section,grade rings and cast iron frame and cover. Largediameter MANHOLES or rectangular MANHOLES can beprecast upon PIPE PRODUCT GUIDE AND TECHNICAL REFERENCE MANUALCONCRETE MANHOLESSECTION INFOOnce this information has been received, astandard shop drawing form is filled out for eachmanhole in the , the total height of the manhole (laid height)is determined, by calculating the difference inelevation between the top of CONCRETE cover andthe lowest pipe invert (or bottom of sump).

2 Thetop of CONCRETE cover elevation is typically set as300mm below finished grade, to provide anallowance for final grade adjustment once themanhole has been , the pipe angles, size and type are determinedand laid out. Angles and pipe inverts are checkedto ensure sufficient clearance between adjacentpipes. All angles are measured clockwise fromthe outlet opening which is taken to be 0 a manhole with two or more inlet pipes, theangle for each pipe relative to the outlet , the distance to the center of each pipeopening is determined ( + to CL). All distances aremeasured from the outside bottom of the manholesection in which the opening is located. Typicallyall openings are in the base section, unless thereis a large change in elevation between pipes.

3 Ifthis is the case, the height of the base section,and intermediate sections will be adjusted toensure that there is sufficient clearance betweenthe opening and the manhole , the manhole sections are selected andlisted, giving the laid height of each piece andany special requirements for each types are listed for each pipe, and anyspecial instructions are otherwise specified, shop drawings aresent to the contractor for review and approval bythe project engineer. Any revisions required bythe engineer or contractor are made, then thefinal approved shop drawings are issued to ourproduction staff for manufacture a manhole for a specific project,certain information is required to develop shopdrawings which are used by our production andshipping staff to manufacture and deliver theappropriate pieces which make up the which is necessary to develop a shopdrawing normally comes from a set of engineeringdrawings containing a plan and profile of the sewerline.

4 The minimum amount of information todetermine required manhole layout: Finished Grade Elevation (or top of concretecover if manhole extends above grade) Size and type of pipe entering the manhole(nominal diameter and pipe material) All pipe inverts (elevation at inside bottom of thepipe taken at the manhole wall) Angles between piping (measured clockwisefrom the outlet pipe which is taken as 0 ) Size of manhole (nominal inside diameter)Additional information which should beprovided would include: Sump depth (if required) Base configuration (with or without benching, withor without bottom slab) Opening type (water tight rubber gasket, smoothor rough cut hole, doghouse opening.) Gasket type for joints / confined rubber o-ring, Ram-Nek butyl rubber strip, no gasket Special allowances for grade adjustment Type of access hatch or cover to be used (cast ironframe and cover, aluminum access hatch, etc.)
