Horizontal auger boring (HAB) offers several advantages over the conventional open-cut method for installation of culverts. In addition to the well-known advantages of trenchless technologies, in terms of less traffic and environmental disruptions, they can provide economic replacements. The main ...

We evaluated the success of these mitigation strategies by 1) comparing results of road surveys conducted 5 years before and 5 years after fencing installation; and 2) monitoring use of culverts by turtles using motion-activated cameras at culvert openings and stationary antennas placed to detect ...
Structural elements: Bridges, tunnels, retaining walls, culverts, and other structural components that support the rail infrastructure. Interoperability and systems integration: This pertains to integrating various subsystems within the railway infrastructure, such as signaling systems, train control systems,...
Therefore, a tail-end evaluation method based on the cost-effectiveness of the whole life cycle of the bridge is proposed. As the ultimate aim is to build a comprehensive BSHM system, it is necessary to consider not only the installation and operation maintenance cost of the bridge structure ...
There were seven culverts placed to drain stormwater. Prefabricated pre-stressed concrete simply supported box girder, and a T-beam girder was installed to support the deck. Figure 2. The route plan of the case study. The duration of the construction project was 12 months. The soil dumping...
Temporary wall support is provided by applying shotcrete (plain or fiber-reinforced), rock anchors (prestressed or passive), and/or the installation of umbrella-shaped fore-polling beams. The type of primary support depends on the geotechnical conditions monitored while excavating. For this reason, ...
3.6. Measures Against Local Inundations Traditionally, measures against local inundations in urban environments consist of engineered drainage systems with concrete channels, pipes, and culverts to quickly drain water under gravity towards larger water bodies such as lakes, rivers, or seas (Table 8)...
