17 hours ago · In several countries, manhole covers made of steel are being stolen, with significant economic losses for private and public entities, and even causing accidents. In this work, a new manhole cover is developed using fibre-reinforced cementitious (FRC) materials and glass fibre-reinforced polymer (GFRP) gratings. Since the GFRP gratings are immune to corrosion, and FRC is a relatively low-cost ...

3 days ago · The choice between sand casting and investment casting depends on a careful evaluation of the specific requirements of the project. Understanding the strengths and limitations of each process, along with considering the various decision-making factors, can lead to the selection of the most suitable casting method for optimal manufacturing outcomes.
5 days ago · Following being extracted from the Yellow River, the alluvial fill is principally in a fluid state, and it is challenging to use vertical drainage measures such as manholes for construction. Nevertheless, drainage measures including the setting of geotextile mats at the bottom of the alluvial fill are more feasible.
