Keywords: fixed structures, inspection, maintenance, qualifications, rail transit system, structures, track, training Summary: This document establishes a standard for the periodic inspection and maintenance of fixed structure rail transit tracks. This includes periodic visual, electrical and mechanical inspections of components that affect safe and reliable operation. This standard also identifies the necessary qualifications for rail transit system employees or contractors who perform periodic inspection and maintenance tasks. Scope and purpose: This standard applies to transit systems and operating entities that own or operate rail transit systems. The purpose of this standard is to verify that tracks are operating safely and as designed through periodic inspection and maintenance, thereby increasing reliability and reducing the risk of hazards and failures. This document represents a common viewpoint of those parties concerned with its provisions, namely operating/ planning agencies, manufacturers, consultants, engineers and general interest groups. The application of any standards, recommended practices or guidelines contained herein is voluntary. In some cases, federal and/or state regulations govern portions of a transit system’s operations. In those cases, the government regulations take precedence over this standard. The North American Transit Service Association (NATSA) and its parent organization APTA recognize that for certain applications, the standards or practices, as implemented by individual agencies, may be either more or less restrictive than those given in this document.

  • The Cause Analysis on the Highway Bridge Expansion Joint and The
    2nd International Conference on Machinery, Materials Engineering, Chemical Engineering and Biotechnology (MMECEB 2015) The Cause Analysis on the Highway Bridge Expansion Joints and the Maintenance of Construction Management Huadong Li Changchun Architecture and Civil Engineering College Jilin Changchun China 130607 [email protected] Keywords: Highway Bridges; Expansion joints; Reasons; Maintenance and construction Abstract. The bridge expansion joints is to adapt to the structure deformation of the bridge, the across device between the bridge structure each couplet of the beam end and the beam end and the abutment back set free deformation. Its role is to ensure that the bridge span structure under temperature change, concrete shrinkage and creep, load according to its static scheme under the influence of factors such as free expansion and deformation, to make the car comfortable, smooth, and waterproof, prevent mud debris into the seam. This paper mainly discusses for the types and their advantages and disadvantages of highway bridge expansion joints as well as expansion joints, and discusses the preventing and curing of diseases. Introduction In recent years with the rapid development of economy, all kinds of infrastructure construction in China ushered in the high speed development stage; Highway bridge project in particular, at the same time, people is becoming more and more attention to highway Bridges safety and life; The main factors are affecting the safety of the highway bridge construction in the construction are produced by the concrete in its shrinkage crack. Under the existing technology, the function of bridge expansion joints can better solve the problem, and has advantages of simple construction, low cost.
