The Structural erformance of flexible pipe for landfill drainage

Authors:  D. F. Rogers, BSc, PhD, CEng, MICE, MIHT, Eur Ing, , The structural performance of perforated plastic pipelines used for landfill drainage is difficult to predict. This paper aims to describe their structural action on the basis of field measurements, and thereby make recommendations for their design and installation. The key requirements for structural support […]

Stress Concentrations Around Circular Holes in Perforated Drainage Pipes

Authors: R.W.I. Brachman, , and R.P. Krushelnitzky, Stress concentrations around circular holes in perforated buried pipes obtained from three-dimensional elastic finite element analysis are presented. The maximum stresses around the perforation were found to depend on the thickness and diameter of the pipe, the diameter of the perforation, the circumferential location of the perforation, and the axial and circumferential […]

Compaction Effects On Strains Within Profiled Thermoplastic Pipes

Authors:  W. I. Brachman1, , I. D. Moore2, , and S. M. Munro3, Results from laboratory tests are reported to establish how pipe deflections, strains and local bending are influenced by the selection of backfill soil and its placement for two profiled thermoplastic culverts. Lined-corrugated high-density polyethylene (HDPE) and poly vinyl chloride (PVC) pipes with a nominal […]

Performance Of Buried HDPE Pipes – Part II: Total Deflection Of The Pipe

Zhou1F. Wang2Y. J. Du3 M. D. Liu4 PhD Candidate Associate Professor Professor and Director Senior Lecturer Total deflection of buried thermoplastic pipes is extensively studied in previous work as it is a service limit state specified in design standards. In this paper, two-dimensional finite-element modeling is conducted to investigate the total deflection of buried high-density polyethylene (HDPE) pipes with a […]

Performance Of Buried HDPE Pipes- Part 1 : Peaking Deflection During Initial Backfilling Process

Zhou1 Y. J. Du2 F. Wang3 M. D. Liu4 PhD Candidate Professor and Director Associate Professor Senior Lecturer Peaking deflection caused by compacting the sidefill, referred to as the maximum change of the pipe diameter divided by the undeformed diameter, is an important parameter in the design and safety check of buried pipelines. However, quantitative equations on the deflection useful for engineering […]

HDPE-Geopipes, Soil-Structure Interaction

Zanzinger LGA, Geotechnical Institute, Nuremberg, Germany Gartung LGA, Geotechnical Institute, Nuremberg, Germany Perforated geopipes are part of the leachate collection system at the base of solid waste landfills. Their structural performance depends on the embedment which is formed by a compacted clay layer, a geomembrane and a sand-bentonite cushion below and coarse gravel above the […]

Investigation of The Failure Behavior of Polyethylene Electrofusion Sockets

Isabelle J. Berger, Andreas Frank, Gerald Pinter, David Nitsche, Dirk Petry Papers # 2018 Las-Vegas Electrofusion (EF) sockets constitute a well-established and practically proven technology for the joining of polyethylene (PE) pressure pipes. As for the pipes, the potential lifetime of such welding connections is beside other properties also depending on the resistance against slow […]
