Field Burial Tests of Corrugated Double Wall PVC Pipe
A new lightweight PVC pipe, consisting of a smooth inner wall and a corrugated outer wall, has been introduced in the U. S. sanitary sewer market in 4 through 10 in. diameters. Field burial...
Long Term Deflection of Buried Plastic Sewer Pipes
During the 70's and the early 80's a research program has been carried out in Sweden regarding the long term behaviour of buried plastic pipes. The program has...
Dynamics of Buried Pipelines
Forced motion of pipelines due to stationary or moving loads is studied. The pipe is modeled as an elastic shell in an elastic (or viscoelastic) medium. The interaction of the shell and...
Determining the In-Place Density of Soils Using the Sleeve Method
The sleeve method of determining the in-place density was developed by Bureau of Reclamation field personnel for cohesionless, fine, gravel soils used for pipe bedding when other methods...
Earth Pressure and Surface Load Effects on Buried Pipelines
Rational techniques for analyzing earth pressure and surface load effects, based on finite element analysis methods, have been developed and applied extensively to the design of buried...
Buried Fiberglass Pipe Response to Field Installation Methods
In 1970 near Yuma, Arizona, a field test installation of 30 inch diameter fiberglass pipe was constructed. Twelve years later the pipeline was remeasured. Measurements of pipe profile,...
Long Term Testing of Centrifugally Cast Glass Fibre Reinforced Plastic Pipes (RIRP)
The paper discusses testing of pipe manufactured by centrifugal molding. The tests included external load tests, internal load, hydrostatic internal pressure, and cyclic internal pressure....
Characterization of Soil Arching Above Buried Conduits
Conventional ways of assessing the effects of soil arching over buried conduits were examined by means of finite element analyses. It was found that neither of the conventional soil arching...
A Study of Inlet Control Alternatives for SWM
A laboratory study of alternatives for effecting inlet control on urban storm sewer systems for stormwater management (SWM) is described. The test facility was a full-size physical model...
KEMCOR?A Chemical and Corrosion Resistant Piping System
KEMCOR is a new underground composite pipe system designed for chemical process use in such industries which require a high degree of corrosion resistance to varying concentrations and...
Field Testing of 84-Inch-Diameter Plastic Pipe
During the summer of 1981, a research project was initiated to monitor strains and deformation in 84-inch diameter RPM (reinforced plastic mortar) pressure pipe. Three 20-foot (6. 1-m)...
Successful Use of Centrifugally Cast Glassfiber Reinforced Plastic (GRP) Pressure Pipes for Public Works in Sweden
Centrifugally cast GRP pipes were introduced in Sweden 17 years ago for industrial applications mainly as a gravity pipe. The process of pipe manufacturing as well as the pipe itself and...
Influence of Frost Action on the Load Exerted on Buried Pipe
When work was started on revising the Swedish code for concrete pipes at the end of the 70's, a research project was carried out to evaluate the risk of increased load due...
Prediction of Fine Sedimentation in Small Marinas
Shoaling due to fine, cohesive sediment deposition in small marina-type basins is governed by basin geometry, hydrodynamic factors and sediment load in outside waters. An easily programmable...
Aggregation and Consolidation of Phosphatic Clays
The consolidation behavior of aggregated phosphatic clays has been investigated using a bench scale centrifuge. It was determined that aggregation of the clays with phosphogypsum, a waste...
Reliability Analysis of Water System Capacity
The paper presents, by means of an application, a few promising analytical methods for estimating bulk water system capacity reliability. In particular, this paper examines the applicability...
Integration of Micro, Mini, and Mainframe Computers in WES Hydraulics Studies
The U. S. Army Corps of Engineers Waterways Experiment Station (WESA) Hydraulics Laboratory is involved in hydraulic studies of navigation and flood control projects of the Army Corps...
Application of Water Budget to Seepage Loss Estimation
The seepage loss for the emergency cooling water spray pond has been calculated by performing a water balance study for the pond. A field test of the spray pond was performed to estimate...
Suspended Sediment Transport from Nonpoint Sources
Precipitation, runoff, and suspended sediment concentration data were collected in a predominantly agricultural watershed in southwestern Illinois from January 1982 through October 1984....
A Ground Water Flow Model for Protection of the Northwest Well Field, Dade County, Florida
A new study was initiated to determine the appropriate cone of depression for the Northwest Well Field and to develop land use restrictions within that area. A finite-difference ground...
