This standard is also available to be included in Standards Subscriptions. The paper provides an overview of the LDS trunk sewer design and construction processes used and provides insight into both the advantages and challenges of direct design when used with very high applied load scenarios.

The LDS trunk sewers in this project range considerably in size and applied loading with extreme loading conditions that included a mm diameter reinforced concrete pipe RCP with covers approaching 16 m and a mm diameter RCP pipe with covers of 21 m.

The use of conventional RCP for this project pushed the practical limitations of both the manufacturing and installation process. Add to Alert PDF.

Direct design pipe was chosen xsce this project as it directly considers shear and radial tension within the pipe wall where traditional indirect design methods do not.

As the pipes were exposed to open cut embankment conditions as well as additional loads due to large offset embankments; ASCE Type 1 and ascce Standard Installation Direct Design SIDD installations were utilized to develop enough soil structure to reduce the bending moment forces and shear in the invert area of the pipe to within acceptable levels.

Nov 12 2: Pipelines Conference Location: This required the design process to re-visit and incorporate many of the original design concepts for SIDD as published by Frank Heger in the late ‘s.

Direct Design

The commentary provides supporting background data. This standard practice may be used as a reference in preparing project specifications based on the SIDD method. Open cut installations under high covers produce very large external loads on rigid pipes which induce considerable shear and ase tension forces within the pipe wall. We have no amendments or corrections for this standard. To account for the interaction 155-98 pipe and soil envelope when determining loads, pressure distributions, moment, thrust and shear, this volume presents the SIDD method for buried precast concrete pipe.

The mm pipeline required additional reinforcing beyond this as even SIDD Type 1 installations required reinforcing schemes that were not feasible within a standard pipe wall section. Based on contractor preference and staging logistics the pipes were designed and installed utilizing open cut methods. Four types of standard embankment installations and four types of standard trench installations are covered in the standard.

It has a population of approximatelypeople. The paper provides an overview of both as well as initial results of inspections that were carried out after representative loading had developed on the pipe to confirm that the pipe response to applied loads was consistent with the design intent.
