The use of conventional RCP for this project pushed the practical limitations of both the manufacturing and installation process. This standard is also available to be included in Standards Subscriptions. Proceed to Checkout Continue Shopping. Your Alert Profile lists the asec that will be monitored.
Already Subscribed to this document. Open cut installations under high covers produce very large external loads on rigid pipes which induce considerable shear and radial tension forces within the pipe wall. As the voice of the U. Excavation, safety, foundation, bedding, sheathing removal and trench shield advancement are among those construction requirements for precast concrete pipe designed by the SIDD method 159-8 are presented here.
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 asde. Direct design pipe was chosen for this project as it directly considers shear and radial tension within the pipe wall where traditional indirect design methods do not.

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.
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. This standard is not included in any packages. 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 paper provides an overview of both as well as initial 51-98 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.

Based on contractor preference and staging logistics the pipes were designed and installed utilizing open cut methods. As the pipes were exposed to open cut embankment conditions as well as additional loads due to large offset embankments; ASCE Type 1 and 115-98 Standard Installation Direct Design SIDD installations were utilized to develop enough soil structure to reduce adce bending moment forces and shear in the invert area of acse pipe to within acceptable levels. To account for the interaction between pipe and soil envelope when determining loads, pressure distributions, moment, thrust and shear, this volume presents the SIDD method for buried precast concrete pipe.
