Earth Pressure Measurements On Buried HDPE Pipe

Authors:  M.L. TALESNICK*, H.-W. XIA†, and I.D. MOORE† An understanding of the stress distributions that act on buried pipes plays a key role in the development and use of design methods for these structures. The radial stresses that develop on buried flexible pipes have been investigated by a number of researchers through experimental, analytical and numerical methods. […]

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 […]

Perbandingan pipa pembuangan bawah tanah HDPE dengan pipa konkrit

1.Diameter pipa antara DN600-DN1600, rasio harga satuan komprehensif dengan diameter yang sama antara pipa HDPE dengan pipa konkrit/semen adalah 1:1.3. 2.Kapasitas aliran HDPE 1.3 kali dari pipa konkrit/semen. Misalnya jika menggunakan pipa konkrit/semen diameter DN800, maka pipa HDPE hanya perlu menggunakan diameter DN700(800/1.3). 3.Penyambungan HDPE yang sederhana dan cepat, meningkatkan kemajuan konstruksi. Dalam kondisi normal, […]
