SPIDA Method for Reinforced Concrete Pipe Design
The required supporting strength of buried pipe is affected by the total load that is imposed upon the pipe and the manner in which the pipe is supported by the surrounding soil. The installation...
Creative Application of Materials Engineering
Society's demand for an aesthetically pleasing and safe constructed environment, along with the construction industry's higher and higher costs, dictate that...
Stabilizing a `Mann'-Sized Sinkhole
On Sept. 21, 1988, a sinkhole suddenly developed beneath a transmission/distribution effluent pipeline on Mann Road in Orange County, FL. Initially it measured 30 ft in diameter and 8...
Optimal Design of Small-Scale Hydro Projects
A nonlinear programming model is developed in this study to determine optimal pipe size, the type and number of turbines and the installed capacity for small scale hydro projects. The...
Appropriate Design and Construction of Conduits for Small and Mini Hydropower
The success of smaller hydro schemes often lies in identifying feasible and economic waterway systems to develop relatively high heads between low intake weir and powerstation. This paper...
Isabella Project?Retrofit of Existing Tunnel
This paper explains conceptual methods of reinforcing and lining the section of the existing tunnel downstream of the three control gates to the exit portal and bifurcation for the power...
Grout Supports Brooklyn Tunneling
At the Red Hook project in Brooklyn, microfine cement grout was injected from the surface to support underground tunneling. The hand-dug tunnel was built to connect to sewer pipes. Subsurface...
A Station With a View
The Port Authority TransHudson Corp. (PATH) is renovating and expanding Exchange Place station, the first stop in New Jersey across the Hudson River from lower Manhattan. To be completed...
The MPSP System: A New Method of Grouting Difficult Rock Formations
In unstable rock masses the traditional stage grouting methods may prove impractical or ineffective. A recent innovation has been the Multiple Packer Sleeved Pipe (MPSP) System. Akin to...
System Reliability Using Expert Opinion
The objective of the study on which this paper is based was to determine the safe performance of several different interior gas piping systems. This paper describes the piping systems...
Water Distribution Network Calibration Considering Multiple Loading Conditions
Through time a water distribution network's carrying capacity is reduced as material collects on pipe walls. The impact varies with each pipe in the system and occurs at an...
Lead: Taking it from the Tap
Medical evidence is lowering the definition of a safe concentration of lead. In turn, there has been an effort to reduce lead in drinking water. Solutions are complicated, as many lead...
Steel Pipe Foundations for Deep Water
Four innovations are helping to make steel pipe piles more popular for foundations in deep water in Southeast Asia. Until recently steel was usually rejected for these applications, because...
Priority Integrated Pipe Evaluation
The selection of the most suitable pipe for a given site involves the consideration of many factors affecting pipe performance. The factors to consider in sewer pipe evaluation and selection...
Specifications for Trenchless Excavation
Many advancements and innovations have developed recently in the utilization of trenchless excavation, techniques throughout the world. In many instances, design details and specifications...
Retrospective Look Into Design Challenges of Boston Interceptors
The purpose of this paper is to share with designers and owners a retrospective evaluation of a major sewer system design effort. The process by which a major sewer design project reaches...
Current Developments in Reinsulating/Waterproofing Underground Steam Mains in New York City
The objective of Con Edison's reinsulation project is to develop the materials and technology necessary to reinsulate those steam distribution mains having excessive thermal...
Pipeline Curvature by Polynomial Approximation
Since start-up of the trans-Alaska pipeline in June of 1977, a variety of techniques have been investigated to monitor pipe settlement and evaluate associated pipe integrity. During the...
